This TOE is represented by a number of various products. They all differentiate by different mask sets
2
with slight - neither functional nor security relevant - modifications, various configuration
3
possibilities, done either by Infineon settings during production or, after delivery, by means of
4
blocking at customer premises. Despite these variation possibilities, all products are derived from the
5
same hardware design results, the M9900 A22, the M9900 G11, the M9905 A11 and the M9906 A11.
6
The TOE can be identified with the Generic Chip Identification Mode (GCIM). The M-number hardware
7
is identified by the bytes 05 and 06, which are the first two bytes of the chip identification number,
8
having for the M9900 always the hexadecimal value of 0x0007, for the M9905 the value 0x0010 and for
9
the M9906 the value 0x0011, the design step, firmware identifier, mask identifier, temperature range
10
and system frequency are also included in the GCIM. Additionally the customer can read the
11
configuration area as defined in the SLE97 Programmer´s Reference Manual [11].
12
Remark 1:
13
The derivatives of the TOE produced in the factory Dresden with the additional top layer on board
14
(WLP, WLB) are managed with an own design step. These derivatives output a C22 in the GCIM for the
15
WLP derivative and a D22 for the WLB derivative, which is always linked to the A22 design step. The
16
C22 and D22 design step is only outputted at the derivatives with the additional top layer. All other
17
identification options, i.e. the various metal option identifiers of the GCIM remain unchanged.
18
The derivatives of the TOE produced in the factory TSMC coming with the additional top layer on
19
board (WLB) are managed with the same design step. These derivatives output a G11 in the GCIM for
20
WLB derivative. All other identification options, i.e. the various metal option identifiers of the GCIM
21
remain unchanged.
22
All products are identical with respect to module design and layout, but may include further package
23
options require flexibility in design and could also depend on user requirements. In these cases one or
24
more additional metal layer are added on top of one of the TOE mask set. These additional metal
25
layers, it could also be more than one, just reroute the pads. Therefore, this last rerouting on top does
26
not change the function of the TOE itself and is depending on the package only. These top metal
27
layers are flexible in design, could depend also on user requirements and are of course not relevant
28
for the security of the TOE. For these reasons, the metal layers are out the scope of the certification
29
and do not belong to the TOE. Of course, in all cases passivation and isolation coating is applied on
30
top of the last layers carrying wires. Further clear declaration and overview is given in chapter 2.1
31
Definition of the TOE.

Despite all these options and the resulting flexibility, all differences are comparable to the scenario
1
where for example someone takes a piece of wire and reconnects the pads of the TOE using a
2
soldering bolt. This does not change anything on the TOE security or security policy.
3
To each of the TOE relevant optional different mask set variants, an individual value is assigned, which
4
is part of the data output of the Generic Chip Identification Mode (GCIM). By that the various hardware
5
mask sets can be clearly identified and differentiated by the GCIM output. The interpretation of the
6
output GCIM data is clearly explained in the user guidance, Hardware Reference Manual [7].
7
There are no other differences between the mask sets the TOE is produced with, and all these changes
8
have no impact on the TOEs security policies and related functions. Details are explained in the user
9
guidance Hardware Reference Manual [7] and in the Errata Sheet [12].
10
In addition to these hardware differences, the M9900, M9905, M9906 allows a maximum of
11
configuration possibilities defined by the customer order following the market needs. A detailed
12
description of the TOE configuration possibilities is given in chapter 2.1.8 TOE Configuration.

1.2 Target of Evaluation overview
1
The TOE comprises the Infineon Technologies AG security controller M9900, M9905, M9906 with
2
specific IC dedicated software and optional RSA, EC, SCL, PSL, HCL, Toolbox and Flash Translation
3
Layer (FTL) libraries.
4
The TOE is a member of the Infineon Technologies AG security controller family SLE97 meeting high
5
requirements in terms of performance and security. The SLE97 family has been developed with a
6
modular concept and different memory configurations, sets of peripherals and interfaces as well as
7
different security features to satisfy market requirements. A summary product description is given in
8
this Security Target (ST).
9
The TOE offer all functions that are both required and useful in security systems, and integrated
10
peripherals that are typically needed in chipcard applications, such as information security,
11
identification, access control, GSM and UMTS projects, electronic banking, digital signature and multi-
12
application cards, ID cards, transportation and e-purse applications.
13
The TOE implements a dedicated security 32-bit RISC CPU designed on the basis of the ARMv7_M
14
architecture designed in 90 nm CMOS technology. The integrated peripheral combine enhanced
15
performance and optimized power consumption for a minimized die size to make the SLE97
16
controllers ideal for chipcard applications. The TOE offer a wide range of peripherals, including a
17
UART (using the ISO interface), four timers, two watchdogs, a CRC module, a true RNG (TRNG),
18
coprocessors for symmetric (e.g. DES, AES) and asymmetric (e.g. RSA, EC) cryptographic algorithms.
19
Additionally a range of communication interfaces, such as GPIO, I2C, SWP, USB, SSC/SPI and a Mifare-
20
compatible Interface are offered to provide maximum flexibility in terms of simultaneously
21
communication ability.
22
The TOE provides a real 32-bit CPU-architecture and is compatible to the ARMv7-M instruction set
23
architecture. The major components of the core system are the 32-bit CPU as a variant of the ARM
24
Secure Core SC300, the Cache system, the Memory Protection Unit and the Memory
25
Encryption/Decryption Unit. The TOE implements a full 32-bit addressing with up to 4 GByte linear
26
addressable memory space, a simple scalable memory management concept and a scalable stack
27
size. The flexible memory concept is built on the non volatile memory, respectively SOLID FLASH™
28
NVM1
. For the SOLID FLASH™ NVM the Unified Channel Programming (UCP) memory technology is
29
used. Additionally an optional external Flash-memory connected via the SPI interface is available.
30
The TOE provides the low-level firmware components Boot Software (BOS) and Resource
31
Management System (RMS) and the high-level firmware Flash Loader (FL) and Mifare-compatible
32
software. The RMS firmware providing some functionality via an API to the Smartcard Embedded
33
Software contains for example SOLID FLASH™ NVM service routines and functionality for the tearing
34
save write into the SOLID FLASH™ NVM. The BOS firmware (BOS-V1 and BOS-V2) is used for test
35
purposes during start-up and the FL allows downloading of user software to the NVM during the
36
manufacturing process. The BOS is implemented in a separated Test-ROM being part of the TOE. For
37
the M9900 two different versions of the BOS are provided (BOS-V1 and BOS-V2). The version BOS-V1
38
(Firmware Identifier 80001141, 80001150, 80001151) executes the UMSLC test during the startup
39
phase, the version BOS-V2 (Firmware Identifier 80001142) does not execute the UMSLC test during the
40
startup phase to short the time duration of the startup phase. The derivate M9906 with Firmware
41
Identifier 80001150 includes the feature “hardening” and the derivate M9905 with Firmware Identifier
42
80001151 includes the features “hardening” and the “Burn-In Test”. The feature “hardening”

that are losing their charge, and, in this very unlikely case, the page is rewritten. The “Burn-In Test”
1
during production is used to stress the chip in a high temperature, high internal voltage and active
2
operation for a certain time and filtering out defect parts to get a low failure rate. The derivatives
3
M9905 and M9906 are qualified for an extended temperature range from -40°C to +105°C.
4
The two cryptographic co-processors serve the need of modern cryptography: The symmetric co-
5
processor (SCP) combines both AES and Triple-DES with dual-key or triple-key hardware acceleration.
6
The Asymmetric Crypto Co-processor, called Crypto2304T in the following, supports RSA-2048 bit
7
(4096-bit with CRT) and Elliptic Curve (EC) cryptography with high performance.
8
A True Random Number Generator (TRNG) specially designed for smart card applications is
9
implemented. The TRNG fulfils the requirements from the functionality class PTG.2 of the AIS31 and
10
produces genuine random numbers which then can be used internally or by the user software.
11
The software part of the TOE consists of the cryptographic libraries RSA and EC and the supporting
12
Toolbox and asymmetric Base libraries and the optional Flash Translation Layer (FTL), the optional
13
Symmetric Crypto Libraries (SCL) and Platform Support Layer (PSL) libraries. The FTL can be used to
14
communicate with the optional external Flash-memory. If a RSA or EC or Toolbox library is part of the
15
shipment, the corresponding asymmetric Base library is automatically included. If the PSL library
16
v4.00.10 is part of the shipment, the RSA, EC, Base libraries v2.05.005 and the SCL library v2.01.011 are
17
automatically included. If the PSL library v5.00.06 is part of the shipment, the RSA, EC, Base libraries
18
v2.07.003, the SCL library v2.04.003 and the HCL library v1.01.003 are automatically included.
19
The RSA library is used to provide a high-level interface to RSA (Rivest, Shamir, Adleman)
20
cryptography implemented on the hardware component Crypto2304T and includes countermeasures
21
against SPA, DPA and DFA attacks. The routines are used for the generation of RSA key pairs1
, RSA
22
signature verification, RSA signature generation and RSA modulus recalculation.The hardware
23
Crypto2304T unit provides the basic long number calculations (add, subtract, multiply, square with
24
1100 bit numbers) with high performance. The RSA library is delivered as object code. The RSA library
25
can perform RSA operations from 512 to 4096 bits. Following the BSI2
recommendations, key lengths
26
below 1976 bits are not included in the certificate.
27
The EC library is used to provide a high-level interface to Elliptic Curve cryptography implemented on
28
the hardware component Crypto2304T and includes countermeasures against SPA, DPA and DFA
29
attacks. The routines are used for ECDSA signature generation, ECDSA signature cerification, ECDSA
30
key generation and Elliptic Curve Diffie-Hellman key agreement. The EC library is delivered as object
31
code. The certification covers the standard NIST [DSS] and Brainpool [ECC] Elliptic Curves with key
32
lengths of 160, 163, 192, 224, 233, 256, 283, 320, 384, 409, 512 or 521 Bits, due to national AIS32
33
regulations by the BSI. Note that there are numerous other curve types, being also secure in terms of
34
side channel attacks on this TOE, which can the user optionally add in the composition certification
35
process.
36
The Toolbox library does not provide cryptographic support or additional security functionality as it
37
provides only the following basic long integer arithmetic and modular functions in software,
38
supported by the cryptographic coprocessor: Addition, subtraction, division, multiplication,
39
comparison, reduction, modular addition, modular subtraction, modular multiplication, modular
40
inversion and modular exponentiation. No security relevant policy, mechanism or function is
41
supported. The toolbox library is deemed for software developers as support for simplified
42
implementation of long integer and modular arithmetic operations.
43
1
Key generation functions are only provided by versions v2.05.005 and v2.07.003 of the RSA library

The asymmetric Base library provides the low level interface to the asymmetric cryptographic
1
coprocessor and has no user available interface. The asymmetric Base library does not provide any
2
security functionality, implements no security mechanisms and does not contribute to a security
3
functional requirement.
4
The Flash Translation Layer Library provides the interface to the external Flash-memory. The Flash
5
Translation Layer Library does not provide any security functionality, implements no security
6
mechanism, and does not contribute to a security functional requirement.
7
The Symmetric Crypto library (SCL) is used to provide a high level interface to DES/3DES and AES
8
symmetric cryptographic operations. It uses the SCP of the underlying hardware but implements also
9
countermeasures against all known weaknesses of the SCP (e.g. dummy calculations and block
10
repetitions). The symmetric crypto library consists of three C-library files Cipher.lib, AES.lib and
11
DES.lib. Those library files will not be distributed individually. Therefore we call those three library
12
files simply the Symmetric Crypto Library (SCL)
13
14
The Hash Library (HCL) provides the hash functions form the SHA-1 and SHA-2 family. The hash
15
functions are hardened against SPA template attacks.
16
The Platform Support Layer (PSL) library is used to provide a standardized interface to the hardware
17
by making use of the RSA, ECC, SCL and HCL libraries. The provided interfaces are syntactically similar
18
to Windows NT device driver calls. The drivers consist merely of wrapper code with no inherent
19
security relevant parts.
20
To fulfill the high security standards for smartcards today and also in the future, this TOE utilizes an
21
integral security concept comprising countermeasure mechanisms specially designed against
22
possible attack scenarios. The TOE provide a robust set of sensors for the purpose of monitoring
23
proper chip operating conditions and detecting fault attack scenarios. The sensors are complemented
24
with digital error detection mechanisms such as parities, error detection codes and instruction stream
25
signatures. Probing and forcing attacks will be counteracted by the security optimized wiring
26
approach, implemented by an Infineon-specific shielding combined with secure wiring of security
27
critical signals, partly masking of security critical signals and by encryption of all memories inside the
28
chip (RAM, ROM, NVM). A decentralized alarm propagation and system deactivation principle is
29
implemented, further decreasing the risk of manipulating and tampering. Additionally, an online
30
check of the security mechanisms is available by using the User Mode Security Life Control (UMSLC).
31
Side-channel attacks (e.g. Timing Attack, SPA, DPA, EMA) are typically defeated using a combination of
32
hardware and software mechanisms, for this the TOE provides several supporting features e.g. trash
33
register writes and instruction interrupt prevention. The Instruction Stream Signature Checking (ISS)
34
is a powerful countermeasure against fault attacks that try to manipulate the execution sequence of
35
the instruction stream. All executed instructions are hashed in the CPUs signature register and the
36
hardware automatically checks the fitting of the values.
37
In this security target the TOE is described and a summary specification is given. The security
38
environment of the TOE during its different phases of the lifecycle is defined. The assets are identified
39
which have to be protected through the security policy. The threats against these assets are
40
described. The security objectives and the security policy are defined, as well as the security
41
requirements. These security requirements are built up of the security functional requirements as part
42
of the security policy and the security assurance requirements. These are the steps during the
43
evaluation and certification showing that the TOE meets the targeted requirements. In addition, the
44
functionality of the TOE matching the requirements is described.

The user software can be implemented in various options depending on the user’s choice and
7
described in chapter 2.1.8. Thereby the user software can be implemented the NVM or coming
8
without user software. In the latter case, the user downloads his entire software on his own using
9
the Flash Loader software.
10
11
The TOE uses also Special Function Registers SFR. These SFR registers are used for general purposes
12
and chip configuration. These registers are located in the SOLID FLASH™ NVM as configuration area

A shielding algorithm finishes the upper layers above security critical signals and wires, finally
15
providing the so called “security optimized wiring”.

The TOE with its integrated security features meets the requirements of all smart card applications
17
such as information integrity, access control, mobile telephone and identification, as well as uses
18
in electronic funds transfer and healthcare systems.

To sum up, the TOE is a powerful smart card IC with a large amount of memory and special peripheral
20
devices with improved performance, optimized power consumption, at minimal chip size while
21
implementing high security.

2 Target of Evaluation Description
1
The TOE description helps to understand the specific security environment and the security policy. In
2
this context the assets, threats, security objectives and security functional requirements can be
3
employed. The following is a more detailed description of the TOE than in [1] as it belongs to the
4
specific TOE.

2.1 Definition of the TOE
7
The TOE comprises three parts:
8
 Hardware of the smart card security controller including all configurations and derivatives
9
 Associated firmware, software and optional software
10
 Documents.
11
The hardware configuration options and configuration methods are described in the chapters 1.1 and
12
2.1.8. The second part of this TOE includes the associated firmware and software required for
13
operation. The TOE can be delivered in various configurations, achieved by means of blocking and
14
depending on the customer order.
15
The documents as described in section 2.1.5 and listed in Table 1, are supplied as user guidance. All
16
product derivatives of this TOE, including all configuration possibilities differentiated by the GCIM
17
data and the configuration information output, are manufactured by Infineon Technologies AG. In the
18
following descriptions, the term “manufacturer” stands short for Infineon Technologies AG, the
19
manufacturer of the TOE. The Smartcard Embedded Software respectively user software is not part of
20
the TOE. New configurations can occur at any time depending on the user blocking or by different
21
configurations applied by the manufacturer. In any case the user is able to clearly identify the TOE
22
hardware, its configuration and proof the validity of the certificate independently, meaning without
23
involving the manufacturer. The various blocking options, as well as the means used for the blocking,
24
are done during the manufacturing process or at user premises. Entirely all means of blocking and the
25
for the blocking involved firmware respectively software parts, used at Infineon Technologies AG
26
and/or the user premises, are subject of the evaluation. All resulting configurations of a TOE derivative
27
are subject of the certificate. All resulting configurations are either at the predefined limits or within
28
the predefined configuration ranges.
29
One or more additional metal layer may be added on top of one of the TOE mask set. These additional
30
metal layers, it could also be more than one, just reroute the pads. Therefore, this last rerouting on
31
top does not change the function of the TOE itself and is depending on the package only, and are not
32
relevant for the security of the TOE. For these reasons, the metal layers are out the scope of the
33
certification and do not belong to the TOE. Of course, in all cases passivation and isolation coating is
34
applied on top of the last layers carrying wires.
35
The firmware used for the TOE internal testing and TOE operation, the firmware and software parts
36
exclusively used for the blocking, the parts of the firmware and software required for cryptographic
37
support are part of the TOE and therefore part of the certification. The documents as described in
38
chapter 2.1.5 are supplied as user guidance.
39
Not part of the TOE and not part of the certification are:
40
 the Smartcard Embedded Software respectively user software, and
41
 the piece of software running at user premises and collecting the BPU receipts coming from the
42
TOE. This BPU software part is the commercially deemed part of the BPU software, not running on

Security Target Lite

Public
The TOE consists of smart card ICs (Security Controllers) meeting high requirements in terms of
1
performance and security. They are manufactured by Infineon Technologies AG in a 90 nm CMOS-
2
technology (L90). This TOE is intended to be used in smart cards for particularly security-relevant
3
applications and for its previous use as developing platform for smart card operating systems
4
according to the lifecycle model from [1]
5
The term Smartcard Embedded Software is used in the following for all operating systems and
6
applications stored and executed on the TOE. The TOE is the platform for the Smartcard Embedded
7
Software. The Smartcard Embedded Software itself is not part of the TOE.
8
The TOE consists of a core system, memories, co-processors, security peripherals, control logic and
9
peripherals. The major components of the core system are the 32-bit CPU (Central Processing Unit),
10
the MPU (Memory Protection Unit), the MED (Memory Encryption/Decryption Unit), the Nested
11
Vectored Interrupt Controller (NVIC), the Instruction Stream Signature Checking (ISS) and the Cache
12
system. The TOE contains the co-processors for RSA/EC (Crypto2304T) and DES/AES (SCP) processing,
13
a CRC module and the peripherals random number generator, four timers and two watchdog timers
14
and several external interface services. All data of the memory block is encrypted, RAM and ROM are
15
equipped with an error detection code (EDC) and the SOLID FLASH™ NVM is equipped in addition with
16
an error correction code (ECC).
17
The memories are connected to the Core with the Memory Bus and the peripherals are connected
18
with the Peripheral Bus.
19
The Analog Modules (ANA) serve for operation within the specified range and manage the alarms. A set
20
of sensors (temperature sensor, backside light detector, glitch sensor) is used to detect excessive
21
deviations from the specified operational range and serve for robustness of the TOE and the UMSLC
22
function can be used to test the alarm lines.
23
The CPU is compatible with the instruction set of the ARMv7_M architecture. Despite its compatibility
24
the CPU implementation is entirely proprietary and not standard.
25
The CPU accesses the memory via the integrated Memory Encryption and Decryption unit (MED). The
26
memory model of the TOE provides two distinct, independent levels. Additionally up to eight regions
27
can be defined with different access rights controlled by the Memory Protection Unit (MPU). Errors in
28
RAM and ROM are automatically detected (EDC, Error Detection Code), in terms of the SOLID FLASH™
29
NVM errors are detected and 1-Bit-errors are also corrected (ECC, Error Correction Code).
30
The controller of this TOE stores both code and data in a linear 4-GByte memory space, allowing direct
31
access without the need to swap memory segments in and out of memory using a memory protection
32
unit.
33
Additionally an optional external Flash-memory (EXF) connected via the SSC/GPIO interfaces is
34
available. The data stored in the external Flash-memory are not protected as the external Flash-
35
memory is not part of the security functional requirements (SFR) of the TOE and not in the scope of
36
the evaluation.
37
The CACHE is a high-speed memory-buffer located between the CPU and the (external) main
38
memories holding a copy of some of the memory contents to enable access, which is considerably
39
faster than retrieving the information from the main memory. In addition to its fast access speed, the
40
CACHE also consumes less power than the main memories. The CACHE is equipped with a integrity
41
check to verify the contents of the cache memories.
42
A True Random Number Generator (TRNG) specially designed for smart card applications is
43
implemented. The TRNG fulfils the requirements from the functionality class PTG.2 of the AIS31 and
44
produces genuine random numbers which then can be used internally or by the user software.
45

Security Target Lite

Public
The implemented sleep mode logic (clock stop mode per ISO/IEC 7816-3) is used to reduce the overall
1
power consumption. The timers permits easy implementation of communication protocols such as
2
T=1 and all other time-critical operations. The UART-controlled I/O interface allows the smart card
3
controller and the terminal interface to be operated independently.
4
The Clock Unit (CLKU) supplies the clocks for all components of the TOE. It generates the system clock
5
and an approximately 1MHz clock for the timers. The 1MHz clock is derived from an internal oscillator,
6
while the system clock may either be based on the internal oscillator clock (internal clock mode) or on
7
an external clock (external clock mode). Additionally a sleep mode is available. When operating in the
8
internal clock mode the system frequency can be configured by the user software combined with the
9
current limitation functionality. In the external clock mode the clock is derived from the external clock
10
and a parameter with the range of 1 to 8. The system frequency may be 1 up to 8 times the externally
11
applied frequency but is of course limited to the maximum system frequency and can be combined
12
with the current limitation function.
13
Two co-processors for cryptographic operations are implemented on the TOE. The Crypto2304T for
14
calculation of asymmetric algorithms like RSA and Elliptic Curve (EC) and the Symmetric
15
Cryptographic Processor (SCP) for dual-key or triple-key triple-DES and AES calculations. These co-
16
processors are especially designed for smart card applications with respect to the security and power
17
consumption. The SCP module computes the complete DES algorithm within a few clock cycles and is
18
especially designed to counter attacks like DPA, EMA and DFA. The Crypto2304T module provides
19
basic functions for the implementation of RSA and EC cryptographic libraries.
20
Note that this TOE can be delivered with both crypto co-processors accessible, or with a blocked SCP
21
or with a blocked Crypto2304T, or with both crypto co-processors blocked. The blocking depends on
22
the customer demands prior to the production of the hardware. No accessibility of the deselected
23
cryptographic co-processors is without impact on any other security policy of the TOE; it is exactly
24
equivalent to the situation where the user decides just not to use the cryptographic co-processors.
25
The cyclic redundancy check (CRC) module is a 16-bit checksum generator, which shall not be used for
26
security-critical data. The TOE includes two timer modules each with two 16-bit general purpose
27
timers. The timer module can be used also as watchdog timer to monitor system operation for
28
possible timeouts and to check the correct order of operation.
29
An Interface Management module, located in the System Module (SYS), provides the TOE with the
30
possibility to maintain two or more data interfaces simultaneously. The TOE is provided with,
31
dependent on the configuration, different peripherals and interfaces as the Universal Serial Bus (USB),
32
the SWP Slave Peripheral (SWP), the Synchronous Serial Communication (SSC), which provides the
33
serial Peripheral Interface (SPI), the GPIO module (GPIO), the Inter-Integrated Cirquit Module (I2C) and
34
the Standard ISO Interface (PAD) to satisfy the different market requirements.
35
36
2.1.2 Firmware of the TOE
37
The entire firmware and software of the TOE consists of different parts:
38
The BOS (Boot Software) and the RMS (Resource Management System) compose the TOE firmware
39
stored in the ROM and the patches hereof in the SOLID FLASH™ NVM. All mandatory functions for start-
40
up and internal testing (BOS) are protected by a dedicated hardware firewall. Additionally two levels
41
are provided, the privileged level and the non-privilege level, both are protected by a hardwired
42
Memory Protection Unit (MPU) setting. For the TOE two different versions of the BOS are provided
43
(BOS-V1 and BOS-V2). The version BOS-V1 (Firmware Identifier 80001141, 80001150, 80001151)
44
executes the UMSLC test during the startup phase, the version BOS-V2 (Firmware Identifier 80001142)
45
19
Security Target Lite
M9900, M9905, M9906
Public
does not execute the UMSLC test during the startup phase to shorten the time duration of the startup
1
phase. For the M9906 the BOS-V1 version (Firmware Identifier 80001150) includes the feature
2
“hardening” and for the M9905 the BOS-V1 version (Firmware Identifier 80001151) includes the
3
features “hardening” and the “Burn-In Test”. The feature “hardening” analyzing a random SOLID
4
FLASHTM
NVM page after every regular program operation for written bits that are losing their charge,
5
and, in this very unlikely case, the page is rewritten. The “Burn-In Test” during production is used to
6
stress the chip in a high temperature, high internal voltage and active operation for a certain time and
7
filtering out defect parts to get a low failure rate. The derivatives M9905 and M9906 are qualified for an
8
extended temperature range from -40°C to +105°C.
9
The RMS is accessible in privileged level only. The FL (Flash Loader) and the Mifare-compatible
10
software compose the TOE software stored in the SOLID FLASH™ NVM. The FL allows downloading of
11
user software to the NVM during the manufacturing process and can be completely deactivated.
12
13
The Mifare-compatible software includes the Mifare-compatible Operating System and additionally
14
the optional library Management of Mifare-compatible Cards (version 01.03.0927 and 01.04.1275) and
15
the optional library Mifare-compatible Reader Mode Support (01.02.0800). The Management of Mifare-
16
compatible Cards provides an API for the management and generation of Mifare-compatible Cards
17
(note that the version 01.04.1275 provides an additionally command). The optional Mifare-compatible
18
Reader Mode support library (01.02.0800) enables an access to external Mifare-compatible cards.
19
The Mifare-compatible software is not part of the certification scope.
20
21
2.1.3 Optional software of the TOE
22
23
The optional software part of the TOE consists of the cryptographic libraries RSA and EC, the
24
supporting Toolbox and asymmetric Base libreries, the optional SCL, the optional Flash Translation
25
Layer (FTL), the optional Platform Support Library (PSL) and the Management of Mifare-compatible
26
Cards library and the Mifare-compatible Reader Mode Support library.
27
The Mifare-compatible software includes support for the optional Management of Mifare-compatible
28
Cards as well as support to ease the implementation of the optional Mifare-compatible Reader Mode
29
Support functionality. It does not support any security relevant policy or function.
30
The RSA library is used to provide a high-level interface to the RSA cryptography implemented on the
31
hardware component Crypto2304T and includes countermeasures against SPA, DPA and DFA attacks.
32
The routines are used for the generation of RSA Key Pairs1
, the RSA signature verification, the RSA
33
signature generation and the RSA modulus recalculation. The module provides the basic long number
34
calculations (add, subtract, multiply, square with 1100-bit numbers) with high performance.
35
The RSA library is delivered as object code and is integrated in this way into the user software. The
36
RSA library can perform RSA operations from 512 to 4096 bits. Depending on the customer’s choice,
37
the TOE can be delivered with the 4096 code portion or with the 2048 code portion only. The 2048
38
code portion is included in both.
39
Part of the evaluation are the RSA straight operations with key lengths from 1024 bits to 2048 bits, and
40
the RSA CRT operations with key lengths of 1024 bits to 4096 bits. Note that key lengths below 1024
41
bits are not included in the certificate.
42
The EC library is used to provide a high level interface to Elliptic Curve cryptography and includes
43
countermeasures against SPA, DPA and DFA attacks. The routines are used for ECDSA signature
44
generation, ECDSA signature verification, ECDSA key generation and Elliptic Curve Diffie-Hellman key
45
agreement. The EC library is delivered as object code and integrated in this way into the user
46
1
Key generation functions are only provided by versions v2.05.005 and v2.07.003 of the RSA library

software. The certification covers the standard NIST [DSS] and Brainpool [ECC] Elliptic Curves with key
1
lengths of 160, 163, 192, 224, 233, 256, 283, 320, 384, 409, 512 or 521 Bits, due to national AIS32
2
regulations by the BSI. Note that there are numerous other curve types, being also secure in terms of
3
side channel attacks on this TOE, which can the user optionally add in the composition certification
4
process.
5
The Toolbox library provides long integer and modular arithmetic operations. It does not support any
6
security relevant policy or function.
7
The Asymmetric Base library provides the low level interface to the asymmetric cryptographic
8
coprocessor for the RSA and ECC cryptographic libraries and has no user available interface. It does
9
not support any security relevant policy or function. The Base, ECC and RSA library can optionally be
10
delivered in two versions:
11
 The version v2.05.005 for the PSL library v4.00.10
12
 The version v2.07.003 for the PSL library v5.00.06
13
14
The Flash Translation Layer (FTL) is the interface to the external Flash-memory and is provided
15
optional to the customer as a binary link library.
16
The Symmetric Crypto library (SCL) is used to provide a high level interface to DES/3DES and AES
17
symmetric cryptographic operations. It uses the SCP of the underlying hardware but implements also
18
countermeasures against all known weaknesses of the SCP (e.g. dummy calculations). The symmetric
19
crypto library consists of three C-library files Cipher.lib, AES.lib and DES.lib. Those library files will not
20
be distributed individually. Therefore we call those three library files simply the Symmetric Crypto
21
Library (SCL). The SCL library can optionally delivered in three versions
22
 The legacy version v2.01.011 for backward compatibility and the PSL v4.00.09
23
 The legacy version v2.02.010 for backward compatibility
24
 The most recent version v2.04.003 for the PSL v5.00.06
25
26
The Hash Cryptographic Library (HCL) provides interfaces to the SHA-1 and SHA-2 family. The HCL can
27
optionally be delivered.
28
29
The Platform Support Layer (PSL) library is used to provide a standardized interface to the hardware,
30
directly or via the RSA, ECC and SCL library. The provided interfaces are syntactically similar to
31
Windows NT device driver calls. The drivers consist only of wrapper code with no inherent security
32
relevant parts. The PSL library can optionally be delivered in two versions

2.1.4 Interfaces of the TOE
2
 The physical interface of the TOE to the external environment is the entire surface of the IC.
3
 The electrical interface of the TOE to the external environment is constituted by the pads of the
4
chip:
5
− The five ISO 7816 pads consist particularly of the contacted RES, I/O, CLK lines and supply lines
6
VCC and GND. The contact based communication is according to ISO 7816/ETSI/EMV.
7
The I2C communication can be driven via the ISO 7816 pads. In this case no other
8
communication using the ISO 7816 pads is possible.
9
− The GPIO interface consists of 4 pads which can be individually configured and combined in
10
various ways.
11
− Also the I2C and the SSC/SPI communication can be exclusively driven via the GPIO pads. In this
12
case no other communication using the GPIO pads is possible.
13
− The USB interface is build out of two dedicated pads for data communication and two pads
14
used from the ISO 7816 interface supplying power and ground.
15
− The SWP interface is build out of one pad to support the SWP slave functionality.
16
 The data-oriented I/O interface to the TOE is formed by the I/O pad.
17
 The interface to the firmware is constituted by special registers used for hardware configuration
18
and control (Special Function Registers, SFR).
19
 The interface of the TOE to the operating system is constituted on one hand by the RMS routine
20
calls and on the other by the instruction set of the TOE.
21
 The interface of the TOE to the test routines is formed by the BOS test routine call, i.e. entry to test
22
mode (OS-TM entry).
23
 The interface to the RSA calculations is defined by the RSA library (optionally).
24
 The interface to the EC calculations is defined by the EC library (optionally).
25
 The interface to the Toolbox basic arithmetic functions is defined by the Toolbox library
26
(optionally).
27
 The interface to the external Flash-memory is defined by the Flash Translation Layer (optionally).
28
 The interface to the symmetric crypto operations DES/3DES/AES is defined by the SCL library
29
(optionally).
30
 The interface to the PSL library is defined by the PSL Specification (optionally).
31
2.1.5 Guidance documentation
32
The guidance documentation is listed in Table 1
33
Finally the certification report may contain an overview of the recommendations to the software
34
developer regarding the secure use of the TOE. These recommendations are also included in the
35
ordinary documentation.

2.1.6 Forms of delivery
1
The TOE can be delivered in form of bare dies, in form of plain wafers, in form of complete modules
2
(wire bond module M4.x, provided as single chip wire bond or as stacked wire bond), or in one of the
3
following an IC cases: MFC5.8 (FCOS), PG-VQFN-8-1, PG-VQFN-32-13 (SMD) and P-M2M4.7-8-1 (for
4
M9905 and M9906). The form of delivery does not affect the TOE security and it can be delivered in any
5
form, as long as the processes applied and sites involved have been subject of the appropriate audit.
6
The delivery can therefore be at the end of phase 3 or at the end of phase 4 which can also include
7
pre-personalization steps according to PP [1]. Nevertheless in both cases the TOE is finished and the
8
extended test features are removed. In this document are always both cases mentioned to avoid
9
incorrectness but from the security policy point of view the two cases are identical.
10
The delivery to the software developer (phase 2  phase 1) contains the development package and is
11
delivered in form of documentation as described above, data carriers containing the tools and
12
emulators as development and debugging tool.
13
Part of the software delivery could also be the Flash Loader program, provided by Infineon
14
Technologies, running on the TOE and receiving via the UART interface the transmitted information of
15
the user software to be loaded into the SOLID FLASH™ NVM memory. The download is only possible
16
after successful authentication. The user software can also be downloaded in an encrypted way. In
17
addition, the user can permanently block further use of the Flash Loader. Whether the Flash Loader
18
program is present or not depends on the procurement order.

2.1.8 TOE Configuration
4
This TOE is represented by various configurations called products, which are all derived from the
5
equal hardware design M9900, M9905 and M9906. The same mask is used to produce different
6
products of the TOE. The first metal mask (called the M1 mask) contains the specific information to
7
identify the TOE.
8
The M9900, M9905 and M9906 product offers different configuration options, which a customer can
9
choose. The mechanism to choose a configuration can be done by the following methods:
10
1. by product selection or dialog-based in Tools,
11
2. via Bill-per-Use (BpU) and Flash Loader (FL),
12
The degree of freedom for configuring the TOE is predefined by Infineon Technologies AG. The list of
13
predefined TOE configurations is given, as an example in Table 5 and in the SLE97 Hardware
14
Reference Manual [7], section 18. Additional the Table 5 gives an overview about the maximum
15
configurable memory and frequency sizes of the TOE.
16
All these possible TOE configurations equal and/or within the specified ranges are covered by the
17
certificate.
18
19
For details about the TOE configurations, please see [ST]
20
21
Beside fix TOE configurations, which can be ordered as usual, this TOE implements optionally the so
22
called Bill-Per-Use (BPU) ability. This solution enables the customer to tailor the product on his own
23
to the required configuration by blocking parts of the chip on demand into the final configuration at
24
his own premises, without further delivery or involving support by Infineon Technology AG.
25
Customers, who are intended to use this feature receiving the TOE in a predefined configuration
26
including the Flash Loader software, enhanced with the BPU blocking software. The blocking
27
information is part of a chip configuration area and can be modified by customers using specific
28
APDUs. Once a final blocking is done, further modifications are disabled.
29
The BPU software part is only present on the products which have been ordered with the BPU option.
30
In all other cases this software is not present on the product.
31
Additionally the user can choose between different firmware BOS versions and optional software
32
libraries.
33
For the M9900 derivative the user can choose the TOE with the BOS firmware in the version BOS-V1 or
34
BOS-V2.
35
The user can choose between one of the Management of Mifare-compatible Cards libraries (version
36
01.03.0927 or 01.04.1275) and the Mifare-compatible Reader Mode Support library (01.02.0800) or the
37
user can choose only one of the three libraries.
38
In the case the TOE is equipped with the External Flash memory the user can choose the Flash
39
Translation Layer (V1.01.0008) library.
40
The hardware of this TOE can be delivered with the following configuration options:
41
 both crypto co-processors accessible
42
 with a blocked SCP
43
24
Security Target Lite
M9900, M9905, M9906
Public
 with a blocked Crypto2304T
1
 both crypto co-processors blocked
2
In case the SCP is blocked, no AES and 3DES computation supported by hardware is possible. In the
3
case the Crypto2304T is blocked, no RSA and EC computation supported by hardware is possible. No
4
accessibility of the deselected cryptographic co-processors is without impact on any other security
5
policy of the TOE; it is exactly equivalent to the situation where the user decides just not to use the
6
cryptographic co-processors.
7
The TOE can be delivered with the following optional libraries
8
 RSA
9
 ECC
10
 Asymmetric Base library for RSA and ECC
11
 Toolbox
12
 SCL for AES/DES
13
 PSL
14
 FTL
15
16
The libraries of this TOE can be delivered according to the following dependencies:
17
 If one of the libraries RSA, EC or Toolbox is delivered, the corresponding asymmetric Base library is
18
automatically part of it.
19
 If the PSL library v4 is delivered, the RSA, EC and Base v2.05.005 libraries as well as the SCL
20
v2.01.011 library are automatically part of it.
21
 If the PSL library v5 is delivered, the RSA, EC and Base v2.07.003 libraries as well as the SCL
22
v2.04.003 library are automatically part of it.
23
24
In case of deselecting one or several of these libraries the TOE does not provide the respective
25
functionality.
26
27
2.1.9 TOE initialization with Customer Software
28
Beside the various TOE configurations further possibilities of how the user inputs his software on the
29
TOE are in place. This provides a maximum of flexibility and for this an overview is given in the
30
following table:

3.4 Conformance Rationale
1
This security target claims strict conformance only to one PP, the PP [1].
2
The Target of Evaluation (TOE) is a typical security IC as defined in PP chapter 1.2.2 comprising:
3
 the circuitry of the IC (hardware including the physical memories),
4
 configuration data, initialisation data related to the IC Dedicated Software and the behaviour of
5
the security functionality
6
 the IC Dedicated Software with the parts
7
 the IC Dedicated Test Software,
8
 the IC Dedicated Support Software.
9
The TOE is designed, produced and/or generated by the TOE Manufacturer.
10
Security Problem Definition:
11
Following the PP [1], the security problem definition is enhanced by adding an additional threat, an
12
organization security policy and an augmented assumption. Including these add-ons, the security
13
problem definition of this security target is consistent with the statement of the security problem
14
definition in the PP [1], as the security target claimed strict conformance to the PP [1].
15
Conformance Rationale:
16
The augmented organizational security policy P.Add-Functions, coming from the additional security
17
functionality of the cryptographic libraries, the augmented assumption A.Key-Function, related to the
18
usage of key-depending function, and the threat memory access violation T.Mem-Access, due to
19
specific TOE memory access control functionality, have been added. These add-ons have no impact
20
on the conformance statements regarding CC [2] and PP [1], with following rational:
21
The security target remains conformant to CC [2], claim 482 as the possibility to introduce additional
22
restrictions is given.
23
The security target fulfils the strict conformance claim of the PP [1] due to the application notes 5, 6
24
and 7 which apply here. By those notes the addition of further security functions and security services
25
are covered, even without deriving particular security functionality from a threat but from a policy.
26
Due to additional security functionality, one coming from the cryptographic libraries - O.Add-
27
Functions, the memory access control - O.Mem-Access, and the hash additional security objectives
28
have been introduced. These add-ons have no impact on the conformance statements regarding CC
29
[2] and PP [1], with following rational:
30
The security target remains conformant to CC [2], claim 482 as the possibility to introduce additional
31
restrictions is given.
32
The security target fulfils the strict conformance of the PP [1] due to the application note 9 applying
33
here. This note allows the definition of high-level security goals due to further functions or services
34
provided to the Security IC Embedded Software.
35
Therefore, the security objectives of this security target are consistent with the statement of the
36
security objectives in the PP [1], as the security target claimed strict conformance to the PP [1].

4 Security Problem Definition (ASE_SPD)
1
The content of the PP [1] applies to this chapter completely.
2
4.1 Threats
3
The threats are directed against the assets and/or the security functions of the TOE. For example,
4
certain attacks are only one step towards a disclosure of assets while others may directly lead to a
5
compromise of the application security. The more detailed description of specific attacks is given later
6
on in the process of evaluation and certification. An overview on attacks is given in PP [1] section 3.2.
7
The threats to security are defined and described in PP [1] section 3.2.

T.Phys-Probing Physical Probing
T.Malfunction Malfunction due to Environmental Stress
T.Leak-Inherent Inherent Information Leakage
T.Leak-Forced Forced Information Leakage
T.Abuse-Func Abuse of Functionality
T.RND Deficiency of Random Numbers
4.1.1 Additional Threat due to TOE specific Functionality
10
The additional functionality of introducing sophisticated privilege levels and access control allows the
11
secure separation between the operation system(s) and applications, the secure downloading of
12
applications after personalization and enables multitasking by separating memory areas and
13
performing access controls between different applications. Due to this additional functionality “area
14
based memory access control” a new threat is introduced.
15
The Smartcard Embedded Software is responsible for its User Data according to the assumption
16
“Treatment of User Data (A.Resp-Appl)”. However, the Smartcard Embedded Software may comprise
17
different parts, for instance an operating system and one or more applications. In this case, such parts
18
may accidentally or deliberately access data (including code) of other parts, which may result in a
19
security violation.
20
The TOE shall avert the threat “Memory Access Violation (T.Mem-Access)” as specified below.
21
T.Mem-Access Memory Access Violation
22
Parts of the Smartcard Embedded Software may cause security violations by accidentally or
23
deliberately accessing restricted data (which may include code) or privilege levels. Any restrictions are
24
defined by the security policy of the specific application context and must be implemented by the
25
Smartcard Embedded Software.

4.1.2 Assets regarding the Threats
1
The primary assets concern the User Data which includes the user data as well as program code
2
(Security IC Embedded Software) stored and in operation and the provided security services. These
3
assets have to be protected while being executed and or processed and on the other hand, when the
4
TOE is not in operation.
5
This leads to four primary assets with its related security concerns:
6
 SC1 Integrity of User Data and of the Security IC Embedded Software (while being
7
executed/processed and while being stored in the TOE’s memories),
8
 SC2 Confidentiality of User Data and of the Security IC Embedded Software (while being processed
9
and while being stored in the TOE’s memories)
10
 SC3 Correct operation of the security services provided by the TOE for the Security IC Embedded
11
Software.
12
 SC4 Continuous availability of random numbers
13
SC4 is an additional security service provided by this TOE which is the availability of random numbers.
14
These random numbers are generated either by a true random number or a deterministic random
15
number generator or by both, when a true random number is used as seed for the deterministic
16
random number generator. Note that the generation of random numbers is a requirement of the PP
17
[1].
18
To be able to protect the listed assets the TOE shall protect its security functionality as well. Therefore
19
critical information about the TOE shall be protected. Critical information includes:
20
 logical design data, physical design data, IC Dedicated Software, and configuration data
21
 Initialisation Data and Pre-personalisation Data, specific development aids, test and
22
characterisation related data, material for software development support, and reticles.
23
The information and material produced and/or processed by the TOE Manufacturer in the TOE
24
development and production environment (Phases 2 up to TOE Delivery) can be grouped as follows:
25
 logical design data,
26
 physical design data,
27
 IC Dedicated Software, Security IC Embedded Software, Initialisation Data and Pre-personalisation
28
Data,
29
 specific development aids,
30
 test and characterisation related data,
31
 material for software development support, and
32
 reticles and products in any form
33
as long as they are generated, stored, or processed by the TOE Manufacturer.
34
For details see PP [1] section 3.1.
35
4.2 Organizational Security Policies
36
The TOE has to be protected during the first phases of their lifecycle (phases 2 up to TOE delivery
37
which can be after phase 3 or phase 4). Later on each variant of the TOE has to protect itself. The
38
organizational security policy covers this aspect.
39
P.Process-TOE Protection during TOE Development and Production

31
Security Target Lite

Public
An accurate identification must be established for the TOE. This requires that each instantiation of the
1
TOE carries this unique identification.
2
The organizational security policies are defined and described in PP [1] section 3.3. Due to the
3
augmentations of PP [1] an additional policy is introduced and described in the next chapter.

4.2.1 Augmented Organizational Security Policy
6
Due to the augmentations of the PP [1] an additional policy is introduced.
7
The TOE provides specific security functionality, which can be used by the Smartcard Embedded
8
Software. In the following specific security functionality is listed which is not derived from threats
9
identified for the TOE’s environment because it can only be decided in the context of the smartcard
10
application, against which threats the Smartcard Embedded Software will use the specific security
11
functionality.
12
The IC Developer / Manufacturer must apply the policy “Additional Specific Security Functionality
13
(P.Add-Functions)” as specified below.
14
15
P.Add-Functions Additional Specific Security Functionality
16
The TOE shall provide the following specific security functionality to the Smartcard Embedded
17
Software:
18
 Advanced Encryption Standard (AES)
19
 Triple Data Encryption Standard (3DES)
20
 Rivest-Shamir-Adleman Cryptography (RSA)
21
 Elliptic Curve Cryptography (EC)
22
 Hash Cryptographic Functions (SHA)
23
24
Note:This TOE can be delivered with the SCP accessible or blocked. The blocking depends on the
25

4.3 Assumptions
7
The TOE assumptions on the operational environment are defined and described in PP [1] section 3.4.
8
The assumptions concern the phases where the TOE has left the chip manufacturer.
9
10
A.Process-Sec-IC Protection during Packaging, Finishing and Personalization:
11
It is assumed that security procedures are used after delivery of the TOE by the TOE Manufacturer up
12
to delivery to the end-consumer to maintain confidentiality and integrity of the TOE and of its
13
manufacturing and test data (to prevent any possible copy, modification, retention, theft or
14
unauthorised use).
15
16
A.Plat-Appl Usage of Hardware Platform:
17
The Security IC Embedded Software is designed so that the requirements from the following
18
documents are met: (i) TOE guidance documents (refer to the Common Criteria assurance class AGD)
19
such as the hardware data sheet, and the hardware application notes, and (ii) findings of the TOE
20
evaluation reports relevant for the Security IC Embedded Software as documented in the certification
21
report.
22
23
A.Resp-Appl Treatment of User Data:
24
All User Data are owned by Security IC Embedded Software. Therefore, it must be assumed that
25
security relevant User Data (especially cryptographic keys) are treated by the Security IC Embedded
26
Software as defined for its specific application context.
27
28
The support of cipher schemas needs to make an additional assumption.

The TOE provides “Additional Specific Security Functionality (O.Add-Functions)” as specified below.
15
O.Add-Functions : Additional Specific Security Functionality
16
The TOE must optionally provide the following specific security functionality to the Smartcard
17

18
 Advanced Encryption Standard (AES)
19
 Triple Data Encryption Standard (3DES)
20
 Rivest-Shamir-Adleman (RSA)

The TOE shall provide “Area based Memory Access Control (O.Mem-Access)” as specified below.
10
O.Mem-Access: Area based Memory Access Control
11
The TOE must provide the Smartcard Embedded Software with the capability to define restricted
12
access memory areas. The TOE must then enforce the partitioning of such memory areas so that
13
access of software to memory areas and privilege levels is controlled as required, for example, in a
14
multi-application environment.

The security objectives for the security IC embedded software development environment and the
19
operational environment is defined in PP [1] section 4.2 and 4.3. The table below lists the security
20
objectives.

Phase 4
OE.Process-Sec-IC Protection during composite
product manufacturing
5.2.1 Clarification of “Usage of Hardware Platform (OE.Plat-Appl)”
23
Regarding the cryptographic services this objective of the environment has to be clarified. The TOE
24
supports cipher schemes as additional specific security functionality. If required the Smartcard
25
Embedded Software shall use these cryptographic services of the TOE and their interface as specified.
26
When key-dependent functions implemented in the Smartcard Embedded Software are just being
27
executed, the Smartcard Embedded Software must provide protection against disclosure of
28
confidential data (User Data) stored and/or processed in the TOE by using the methods described
29
under “Inherent Information Leakage (T.Leak-Inherent)” and “Forced Information Leakage (T.Leak-
30
Forced)“.
31
The objectives of the environment regarding the memory, software and firmware protection and the
32
SFR and peripheral-access-rights-handling have to be clarified. For the separation of different
33
36
Security Target Lite

Public
applications the Smartcard Embedded Software (Operating System) may implement a memory
1
management scheme based upon security functions of the TOE.
2
5.2.2 Clarification of “Treatment of User Data (OE.Resp-Appl)”
3
Regarding the cryptographic services this objective of the environment has to be clarified. By
4
definition cipher or plain text data and cryptographic keys are User Data. The Smartcard Embedded
5
Software shall treat these data appropriately, use only proper secret keys (chosen from a large key
6
space) as input for the cryptographic function of the TOE and use keys and functions appropriately in
7
order to ensure the strength of cryptographic operation.
8
This means that keys are treated as confidential as soon as they are generated. The keys must be
9
unique with a very high probability, as well as cryptographically strong. For example, it must be
10
ensured that it is beyond practicality to derive the private key from a public key if asymmetric
11
algorithms are used. If keys are imported into the TOE and/or derived from other keys, quality and
12
confidentiality must be maintained. This implies that appropriate key management has to be realized
13
in the environment.
14
Regarding the memory, software and firmware protection and the SFR and peripheral access rights
15
handling these objectives of the environment has to be clarified. The treatment of User Data is also
16
required when a multi-application operating system is implemented as part of the Smartcard
17
Embedded Software on the TOE. In this case the multi-application operating system should not
18
disclose security relevant user data of one application to another application when it is processed or
19
stored on the TOE.
20
5.2.3 Clarification of “Protection during Composite product
21
manufacturing (OE.Process-Sec-IC)”
22
The protection during packaging, finishing and personalization includes also the personalization
23
process (Flash Loader software) and the personalization data (TOE software components) during
24
Phase 4, Phase 5 and Phase 6.
25
5.3 Security Objectives Rationale
26
The security objectives rationale of the TOE are defined and described in PP [1] section 4.4. For
27
organizational security policy P.Add-Functions, OE.Plat-Appl and OE.Resp-Appl the rationale is given
28
in the following description.

30
Assumption, Threat or Organisational
Security Policy
Security Objective
P.Add-Functions O.Add-Functions
A.Key-Function OE.Plat-Appl
OE.Resp-Appl
T.Mem-Access O.Mem-Access
31
The justification related to the security objective “Additional Specific Security Functionality
32
(O.Add-Functions)” is as follows: Since O.Add-Functions requires the TOE to implement exactly the
33
same specific security functionality as required by P.Add-Functions; the organizational security policy
34
is covered by the objective.
35
37
Security Target Lite
M9900, M9905, M9906
Public
Nevertheless the security objectives O.Leak-Inherent, O.Phys-Probing, O.Malfunction, O.Phys-
1
Manipulation and O.Leak-Forced define how to implement the specific security functionality required
2
by P.Add-Functions. (Note that these objectives support that the specific security functionality is
3
provided in a secure way as expected from P.Add-Functions.) Especially O.Leak-Inherent and O.Leak-
4
Forced refer to the protection of confidential data (User Data or TSF data) in general. User Data are
5
also processed by the specific security functionality required by P.Add-Functions.
6
Compared to PP [1] clarification has been made for the security objective “Usage of Hardware
7
Platform (OE.Plat-Appl)”: If required the Smartcard Embedded Software shall use these cryptographic
8
services of the TOE and their interface as specified. In addition, the Smartcard Embedded Software
9
must implement functions which perform operations on keys (if any) in such a manner that they do
10
not disclose information about confidential data. The non disclosure due to leakage A.Key-Function
11
attacks is included in this objective OE.Plat-Appl. This addition ensures that the assumption
12
A.Plat-Appl is still covered by the objective OE.Plat-Appl although additional functions are being
13
supported according to O.Add-Functions.
14
Compared to the PP [1] a clarification has been made for the security objective “Treatment of User
15
Data (OE.Resp-Appl)”: By definition cipher or plain text data and cryptographic keys are User Data. So,
16
the Smartcard Embedded Software will protect such data if required and use keys and functions
17
appropriately in order to ensure the strength of cryptographic operation. Quality and confidentiality
18
must be maintained for keys that are imported and/or derived from other keys. This implies that
19
appropriate key management has to be realized in the environment. That is expressed by the
20
assumption A.Key—Function which is covered from OE.Resp–Appl. These measures make sure that
21
the assumption A.Resp-Appl is still covered by the security objective OE.Resp-Appl although
22
additional functions are being supported according to P.Add-Functions.
23
Compared to the PP [1] an enhancement regarding memory area protection has been established.
24
The clear definition of privilege levels for operated software establishes the clear separation of
25
different restricted memory areas for running the firmware, downloading and/or running the
26
operating system and to establish a clear separation between different applications. Nevertheless, it
27
is also possible to define a shared memory section where separated applications may exchange
28
defined data. The privilege levels clearly define by using a hierarchical model the access right from
29
one level to the other. These measures ensure that the threat T.Mem-Access is clearly covered by the
30
security objective O.Mem-Access.
31
The justification of the additional policy and the additional assumption show that they do not
32
contradict to the rationale already given in the Protection Profile for the assumptions, policy and
33
threats defined there.

6 Extended Component Definition (ASE_ECD)
1
There are four extended components defined and described for the TOE:
2
 the family FCS_RNG at the class FCS Cryptographic Support
3
 the family FMT_LIM at the class FMT Security Management
4
 the family FAU_SAS at the class FAU Security Audit
5
 the component FPT_TST.2 at the class FPT Protection of the TSF
6
The extended components FMT_LIM and FAU_SAS are defined and described in PP [1] section 5. The
7
components FPT_TST.2 and FCS_RNG are defined in the following sections.
8
6.1 “Subset TOE security testing (FPT_TST)”
9
The security is strongly dependent on the correct operation of the security functions. Therefore, the
10
TOE shall support that particular security functions or mechanisms are tested in the operational
11
phase (Phase 7). The tests can be initiated by the Smartcard Embedded Software and/or by the TOE or
12
is done automatically and continuously.
13
Part 2 of the Common Criteria provides the security functional component “TSF testing (FPT_TST.1)”.
14
The component FPT_TST.1 provides the ability to test the TSF’s correct operation.
15
For the user it is important to know which security functions or mechanisms can be tested. The
16
functional component FPT_TST.1 does not mandate to explicitly specify the security functions being
17
tested. In addition, FPT_TST.1 requires verification of the integrity of TSF data and of the stored TSF
18
executable code which might violate the security policy. Therefore, the functional component”Subset
19
TOE security testing (FPT_TST.2)” of the family TSF self test has been newly created. This component
20
allows that particular parts of the security mechanisms and functions provided by the TOE are tested.
21
6.2 Definition of FPT_TST.2
22
The functional component “Subset TOE security testing (FPT_TST.2)” has been newly created
23
(Common Criteria Part 2 extended). This component allows that particular parts of the security
24
mechanisms and functions provided by the TOE can be tested after TOE Delivery or are tested
25
automatically and continuously during normal operation transparent for the user.
26
This security functional component is used instead of the functional component FPT_TST.1 from
27
Common Criteria Part 2. For the user it is important to know which security functions or mechanisms
28
can be tested. The functional component FPT_TST.1 does not mandate to explicitly specify the
29
security functions being tested. In addition, FPT_TST.1 requires verifying the integrity of TSF data and
30
stored TSF executable code which might violate the security policy.
31
The functional component “Subset TOE testing (FPT_TST.2)” is specified as follows (Common Criteria
32

The above marked extended components FMT_LIM.1 and FMT_LIM.2 are introduced in PP [1] to define
4
the IT security functional requirements of the TOE as an additional family (FMT_LIM) of the Class FMT
5
(Security Management). This family describes the functional requirements for the Test Features of the
6
TOE. The new functional requirements were defined in the class FMT because this class addresses the
7
management of functions of the TSF.

TOE of the Class FAU (Security Audit). This family describes the functional requirements for the
10
storage of audit data and is described in the next chapter.
11
The requirement FPT_TST.2 is the subset of TOE testing and originated in [3]. This requirement is
12
given as the correct operation of the security functions is essential. The TOE provides mechanisms to

7.1.1.2 FAU_SAS
11
To define the security functional requirements of the TOE an additional family (FAU_SAS) of the Class
12
FAU (Security Audit) is defined here. This family describes the functional requirements for the storage
13
of audit data. It has a more general approach than FAU_GEN, because it does not necessarily require
14
the data to be generated by the TOE itself and because it does not give specific details of the content
15
of the audit records.
16
The TOE shall meet the requirement “Audit storage (FAU_SAS.1)” as specified below (Common
17
Criteria Part 2 extended).

FAU_SAS.1.1 The TSF shall provide the test process before TOE Delivery with the capability
23
to store the Initialization Data and/or Pre-personalization Data and/or
24
supplements of the Security IC Embedded Software in the not changeable
25
configuration page area and non-volatile memory.
26
7.1.2 Subset of TOE testing
27
The security is strongly dependent on the correct operation of the security functions. Therefore, the
28
TOE shall support that particular security functions or mechanisms are tested in the operational
29
phase (Phase 7). The tests can be initiated by the Smartcard Embedded Software and/or by the TOE.

The TOE shall meet the requirement “Subset TOE testing (FPT_TST.2)” as specified below (Common
31

7.2 Memory access control
6
Usage of multiple applications in one Smartcard often requires code and data separation in order to
7
prevent that one application can access code and/or data of another application. For this reason the
8
TOE provides Area based Memory Access Control. The underlying Memory Protection Unit (MPU) is
9
documented in section 4 of the [7].
10
The security service being provided is described in the Security Function Policy (SFP) Memory Access
11
Control Policy. The security functional requirement “Subset access control (FDP_ACC.1)” requires that
12
this policy is in place and defines the scope were it applies. The security functional requirement
13
“Security attribute based access control (FDP_ACF.1)” defines security attribute usage and
14
characteristics of policies. It describes the rules for the function that implements the Security
15
Function Policy (SFP) as identified in FDP_ACC.1. The decision whether an access is permitted or not is
16
taken based upon attributes allocated to the software. The Smartcard Embedded Software defines
17
the attributes and memory areas. The corresponding permission control information is evaluated “on-
18
the-fly” by the hardware so that access is granted/effective or denied/inoperable.
19
The security functional requirement “Static attribute initialisation (FMT_MSA.3)” ensures that the
20
default values of security attributes are appropriately either permissive or restrictive in nature.
21
Alternative values can be specified by any subject provided that the Memory Access Control Policy
22
allows that. This is described by the security functional requirement “Management of security
23
attributes (FMT_MSA.1)”. The attributes are determined during TOE manufacturing (FMT_MSA.3) or
24
set at run-time (FMT_MSA.1).
25
From TOE’s point of view the different roles in the Smartcard Embedded Software can be
26
distinguished according to the memory based access control. However the definition of the roles
27
belongs to the user software.
28
The following Security Function Policy (SFP) Memory Access Control Policy is defined for the
29
requirement “Security attribute based access control (FDP_ACF.1)”:
30
31
32
7.2.1 Memory Access Control Policy
33
The TOE shall support the standard ARMv7 Protected Memory System Architecture model.
34
The MPU provides full support for:
35
 Protection regions.
36
 Overlapping protection regions, with ascending region priority:
37
− Region 7 = highest priority.
38
− Region 0 = lowest priority.
39
 Access permissions.
40
46

Public
 MPU mismatches and permission violations invoke the programmable-priority MemManage fault
1
handler.
2
The MPU can be used to:
3
 Enforce privilege rules, preventing user applications from corrupting operating system data.
4
 Separate processes, blocking the active task from accessing other tasks’ data.
5
 Enforce access rules, allowing memory regions to be defined as read-only or detecting unexpected
6
memory accesses.
7
8
Subjects, Objects and Operations of the policy
9
 Subjects: privilege or non-privilege level of the ARM processor
10
 Objects: memory/code addresses
11
 Operations: Read a/o write a/o execute access
12
13
Attributes of the policy:
14
 MPU enable/disable bit.
15
 8 regions with the following attributes
16
− A unique priority
17
− The enable bit
18
− the start address and size
19
− an access matrix which defines if an Operation of a Subject to an Object lying in the region is
20
allowed or denied
21
 The default region with the following security attribute:
22
− A bit which defines if an Operation for the Subject (privilege level) is allowed or if no Operation
23
is allowed for any Subject.
24
25
Roles of the policy:
26
The roles correspond 1-1 to the subjects.
27
28
Properties of the policy:
29
 If an address is contained in multiple enabled regions, then the region with the highest priority
30
defines the access rights.
31
 If an address is contained in no region then the default region defines the access rights.
32
 The region defining the access rights checks in the access matrix if the Subject has access to the
33
Object with respect to the desired Operation. In case the access is denied the MPU throws an
34
access violation exception.

The following additional specific security functionality is implemented in the TOE:
2
FCS_COP.1 Cryptographic operation requires a cryptographic operation to be performed in
3
accordance with a specified algorithm and with a cryptographic key of specified sizes. The specified
4
algorithm and cryptographic key sizes can be based on an assigned standard; dependencies are
5
discussed in Section 7.6.1.1.
6
The following additional specific security functionality is implemented in the TOE:
7
 Advanced Encryption Standard (AES)
8
 Triple Data Encryption Standard (3DES)
9
 Elliptic Curve Cryptography (EC)
10
 Rivest-Shamir-Adleman (RSA)1

Preface regarding Security Level related to Cryptography:
14
The strength of the cryptographic algorithms was not rated in the course of the product certification
15
(see BSIG Section 9, Para.4, Clause 2). But Cryptographic Functionalities with a security level of
16
lower than 100 bits can no longer be regarded as secure without considering the application
17
context. Therefore for these functionalities it shall be checked whether the related crypto
18
operations are appropriate for the intended system. Some further hints and guidelines can be
19
derived from the 'Technische Richtlinie BSI TR-02102', www.bsi.bund.de.
20
Any Cryptographic Functionality that is marked in column 'Security Level above 100 Bits' of the
21
following table with 'no' achieves a security level of lower than 100 Bits (in general context).

The table above gives an overview, how the security functional requirements are combined to meet
5
the security objectives. The detailed justification is given in the following:
6
The justification related to the security objective “Additional Specific Security Functionality
7
(O.Add-Functions)” is as follows:
8
The security functional requirement(s) “Cryptographic operation (FCS_COP.1)” exactly requires those
9
functions to be implemented which are demanded by O.Add-Functions. FCS_CKM.1/RSA supports the
10
generation of RSA keys, FCS_CKM.1/EC supports the generation of EC keys needed for this
11
cryptographic operations. Therefore, FCS_COP.1/RSA, FCS_COP.1/RSA_PSL, FCS_COP.1/ECDSA,
12
FCS_COP.1/ECDSA_PSL, FCS_COP.1/ECDH, FCS_COP.1/ECDH_PSL and FCS_CKM.1/RSA and
13
FCS_CKM/EC are suitable to meet the security objective. The use of the supporting libraries Toolbox
14
1
Key generation functions are only provided by versions v2.05.005 and v2.07.003 of the RSA library
67
Security Target Lite

Public
and Base has no impact on any security functional requirement nor does its use generate additional
1
requirements.
2
Nevertheless, the developer of the Smartcard Embedded Software must ensure that the additional
3
functions are used as specified and that the User Data processed by these functions are protected as
4
defined for the application context. These issues are addressed by the specific security functional
5
requirements:
6
 [FDP_ITC.1 Import of user data without security attributes or
7
FDP_ITC.2 Import of user data with security attributes or
8
FCS_CKM.1 Cryptographic key generation],
9
 FCS_CKM.4 Cryptographic key destruction.
10
All these requirements have to be fulfilled to support OE.Resp-Appl for FCS_COP.1/DES,
11
FCS_COP.1/DES_SCL, FCS_COP.1/DES_PSL, FCS_COP.1/DES_MAC_PSL and for FCS_COP.1/AES,
12
FCS_COP.1/AES_SCL, FCS_COP.1, FCS_COP.1/AES_PSL, FCS_COP.1/AES_MAC_PSL. For the
13
FCS_COP.1/RSA , FCS_COP.1/RSA _PSL and FCS_COP.1/ECDSA , FCS_COP.1/ECDSA_PSL and
14
FCS_COP.1/ECDH, FCS_COP.1/ECDH_PSL the FCS_CKM.1/RSA and FCS_CKM.1/EC are optional, since
15
they are fulfilled by the TOE or may be fulfilled by the environment as the user can generate keys
16
externally additionally.
17
The security functional requirements required to meet the security objectives O.Leak-Inherent,
18
O.Phys-Probing, O.Malfunction, O.Phys-Manipulation and O.Leak-Forced define how to implement the
19
specific security functionality. However, key-dependent functions could be implemented in the
20
Smartcard Embedded Software.
21
The usage of cryptographic algorithms requires the use of appropriate keys. Otherwise these
22
cryptographic functions do not provide security. The keys have to be unique with a very high
23
probability, and must have a certain cryptographic strength etc. In case of a key import into the TOE
24
(which is usually after TOE delivery) it has to be ensured that quality and confidentiality are
25
maintained. Keys for 3DES and AES are provided by the environment, the keys for RSA and EC
26
algorithms can be provided either by the TOE or the environment.
27
In this ST the objectives for the environment OE.Plat-Appl and OE.Resp-Appl have been clarified. The
28
Smartcard Embedded Software defines the use of the cryptographic functions FCS_COP.1 provided by
29
the TOE. The requirements for the environment FDP_ITC.1, FDP_ITC.2, FCS_CKM.1 and FCS_CKM.4
30
support an appropriate key management. These security requirements are suitable to meet OE.Resp-
31
Appl.
32
The justification of the security objective and the additional requirements (both for the TOE and its
33
environment) show that they do not contradict to the rationale already given in the Protection Profile
34
for the assumptions, policy and threats defined there.
35
The security functional component Subset TOE security testing (FPT_TST.2) has been newly created
36
(Common Criteria Part 2 extended). This component allows that particular parts of the security
37
mechanisms and functions provided by the TOE can be tested after TOE Delivery. This security
38
functional component is used instead of the functional component FPT_TST.1 from Common Criteria
39
Part 2. For the user it is important to know which security functions or mechanisms can be tested. The
40
functional component FPT_TST.1 does not mandate to explicitly specify the security functions being
41
tested. In addition, FPT_TST.1 requires verification of the integrity of TSF data and stored TSF
42
executable code which might violate the security policy.
43
The tested security enforcing functions are SF_DPM Device Phase Management and SF_PMA
44
Protection against modifying attacks.
45
68
Security Target Lite
M9900, M9905, M9906
Public
The security functional requirement FPT_TST.2 will detect attempts to conduce a physical
1
manipulation on the monitoring functions of the TOE. The objective of FPT_TST.2 is O.Phys-
2
Manipulation. The physical manipulation will be tried to overcome security enforcing functions.
3
The security functional requirement “Subset access control (FDP_ACC.1)” with the related Security
4
Function Policy (SFP) “Memory Access Control Policy” exactly require the implementation of an area
5
based memory access control as required by O.Mem-Access. The related TOE security functional
6
requirements FDP_ACC.1, FDP_ACF.1, FMT_MSA.3, FMT_MSA.1 and FMT_SMF.1 cover this security
7
objective. The implementation of these functional requirements is represented by the dedicated
8
privilege level concept.
9
The justification of the security objective and the additional requirements show that they do not
10
contradict to the rationale already given in the Protection Profile for the assumptions, policy and
11
threats defined there. Moreover, these additional security functional requirements cover the
12
requirements by [3] user data protection of chapter 11 which are not refined by the PP [1].
13
Nevertheless, the developer of the Smartcard Embedded Software must ensure that the additional
14
functions are used as specified and that the User Data processed by these functions are protected as
15
defined for the application context. The TOE only provides the tool to implement the policy defined in
16
the context of the application.
17
The justification related to the security objective “Protection against Malfunction due to
18
Environmental Stress (O.Malfunction)” is as follows:
19
The security functional requirement “Stored data integrity monitoring (FDP_SDI.1)” requires the
20
implementation of an Error Detection (EDC) algorithm which detects integrity errors of the data stored
21
in RAM, ROM and SOLID FLASH™ NVM (in the SOLID FLASH™ NVM more bit errors are detected). By this
22
the malfunction of the TOE using corrupt data is prevented. Therefore FDP_SDI.1 is suitable to meet
23
the security objective.
24
The security functional requirement “Stored data integrity monitoring and action (FDP_SDI.2)”
25
requires the implementation of an integrity observation and correction which is implemented by the
26
Error Detection (EDC) and Error Correction (ECC) measures. The EDC is present in RAM and ROM of the
27
TOE while the ECC is realized in the SOLID FLASH™ NVM. These measures detect and inform about one
28
and more bit errors. In case of the SOLID FLASH™ NVM 1 bit errors of the data are corrected
29
automatically. By the ECC mechanisms it is prevented that the TOE uses corrupt data. Therefore
30
FDP_SDI.2 is suitable to meet the security objective.
31
The CC part 2 defines the component FIA_SOS.2, which is similar to FCS_RNG.1, as follows:
32
33
FIA_SOS.2 TSF Generation of secrets
34
Hierarchical to: No other components.
35
Dependencies: No dependencies.
36
FIA_SOS.2.1 The TSF shall provide a mechanism to generate secrets that meet
37
[assignment:adefined quality metric].
38
FIA_SOS.2.2 The TSF shall be able to enforce the use of TSF generated secrets for
39
[assignment: list of TSF functions].
40
41
The CC part 2, annex G.3 [3], states: “This family defines requirements for mechanisms that enforce
42
defined quality metrics on provided secrets, and generate secrets to satisfy the defined metric“. Even
43
69
Security Target Lite
M9900, M9905, M9906
Public
the operation in the element FIA_SOS.2.2 allows listing the TSF functions using the generated secrets.
1
Because all applications discussed in annex G.3 are related to authentication, the component
2
FIA_SOS.2 is also intended for authentication purposes while the term “secret” is not limited to
3
authentication data (cf. CC part 2, paragraphs 39-42).
4
Paragraph 685 in the CC part 2 [3] recommends to use the component FCS_CKM.1 to address random
5
number generation. However, this may hide the nature of the secrets used for key generation and
6
does not allow describing random number generation for other cryptographic methods (e.g.,
7
challenges, padding), authentication (e.g., password seeds), or other purposes (e.g., blinding as a
8
countermeasure against side channel attacks).
9
The component FCS_RNG addresses general RNG, the use of which includes but is not limited to
10
cryptographic mechanisms. FCS_RNG allows specifying requirements for the generation of random
11
numbers including necessary information for the intended use. These details describe the quality of
12
the generated data where other security services rely on. Thus by using FCS_RNG a ST or PP author is
13
able to express a coherent set of SFRs that include or use the generation of random numbers as a
14
security service.

The security functional requirement “Cryptographic key management (FCS_CKM)” met by TOE, has
1
the following dependencies:
2
 [FCS_CKM.2 Cryptographic key distribution, or
3
 FCS_COP.1 Cryptographic operation]
4
 FCS_CKM.4 Cryptographic key destruction.
5
These requirements all address the appropriate management of cryptographic keys used by the
6
specified cryptographic function and are not part of the PP [1]. Most requirements concerning key

management shall be fulfilled by the environment since the Smartcard Embedded Software is

19
environment shall meet the requirements FDP_ITC.1 or FDP_ITC.2 as defined in [3], section 11.7.

For the security functional requirement FCS_COP.1/RSA, FCS_COP.1/RSA_PSL, FCS_COP.1/ECDSA,
21
and FCS_COP.1/ECDH, the respective dependency FCS_CKM.1 has to be fulfilled by the TOE with the
22
security functional requirement FCS_CKM.1/RSA (for FCS_COP.1/RSA) and FCS_CKM.1/EC (for
23
FCS_COP.1/ECDSA and FCS_COP.1/ECDH) as defined in section 7.1.4. Additionally the requirement
24
FCS_CKM.1 can be fulfilled by the environment as defined in [3], section 10.1.
25
For the security functional requirement FCS_COP.1/ECDSA_PSL and FCS_COP.1/ECDH_PSL, the
26
respective dependency FCS_CKM.1 does not apply, because the PSL does not provide a key
27
generation operation for elliptic curves.
28
For the security functional requirement FCS_CKM.1/RSA and FCS_CKM.1/EC the respective
29
dependency FCS_COP.1 is fulfilled by the TOE. The respective dependency FCS_CKM.4 has to be
30
fulfilled by the environment. That means, the environment shall meet the requirement FCS_CKM.4 as
31
defined in [3], section 10.1.
32
For the security functional requirement FCS_COP.1/SHA and FCS_COP.1/SHA_PSL the respective
33
dependencies are not applicable, because no keys are involved.
34
The cryptographic libraries RSA and EC and the Toolbox library are delivery options. If one of the
35
libraries RSA, EC or Toolbox are delivered, the asymmetric Base Lib is automatically part of it.
36
Therefore the user may choose a free combination of these libraries. In case of deselecting one or
37
several of these libraries the TOE does not provide the respective functionality Additional Specific
38
Security Functionality Rivest-Shamir-Adleman Cryptography (RSA) and/or Elliptic Curve Cryptography
39
(EC). The Toolbox and asymmetric Base Library are no cryptographic libraries and provide no

7.6.2 Rationale of the Assurance Requirements
2
The chosen assurance level EAL5 and the augmentation with the requirements ALC_DVS.2 and
3
AVA_VAN.5 were chosen in order to meet the assurance expectations explained in the following
4
paragraphs. In Table 18 the different assurance levels are shown as well as the augmentations. The
5
augmentations are in compliance with the Protection Profile.
6
An assurance level EAL5 with the augmentations ALC_DVS.2 and AVA_VAN.5 are required for this type
7
of TOE since it is intended to defend against highly sophisticated attacks without protective
8
environment. This evaluation assurance package was selected to permit a developer to gain
9
maximum assurance from positive security engineering based on good commercial practices. In order
10
to provide a meaningful level of assurance that the TOE provides an adequate level of defence against
11
such attacks, the evaluators should have access to all information regarding the TOE including the
12
TSF internals, the low level design and source code including the testing of the modular design.
13
Additionally the mandatory technical document “Application of Attack Potential to Smartcards” [10]
14
shall be taken as a basis for the vulnerability analysis of the TOE.
15
16
17
ALC_DVS.2 Sufficiency of security measures
18
Development security is concerned with physical, procedural, personnel and other technical
19
measures that may be used in the development environment to protect the TOE.
20
In the particular case of a Security IC the TOE is developed and produced within a complex and
21
distributed industrial process which must especially be protected. Details about the implementation,
22
(e.g. from design, test and development tools as well as Initialization Data) may make such attacks
23
easier. Therefore, in the case of a Security IC, maintaining the confidentiality of the design is very
24
important.
25
This assurance component is a higher hierarchical component to EAL5 (which only requires
26
ALC_DVS.1). ALC_DVS.2 has no dependencies.
27

M9900, M9905, M9906
Public
AVA_VAN.5 Advanced methodical vulnerability analysis
1
Due to the intended use of the TOE, it must be shown to be highly resistant to penetration attacks.
2
This assurance requirement is achieved by the AVA_VAN.5 component.
3
Independent vulnerability analysis is based on highly detailed technical information. The main intent
4
of the evaluator analysis is to determine that the TOE is resistant to penetration attacks performed by
5
an attacker possessing high attack potential.
6
AVA_VAN.5 has dependencies to ADV_ARC.1 “Security architecture description”, ADV_FSP.2 “Security
7
enforcing functional specification”, ADV_TDS.3 “Basic modular design”, ADV_IMP.1 “Implementation
8
representation of the TSF”, AGD_OPE.1 “Operational user guidance”, and AGD_PRE.1 “Preparative
9
procedures”.
10
All these dependencies are satisfied by EAL5.
11
It has to be assumed that attackers with high attack potential try to attack Security ICs like smart
12
cards used for digital signature applications or payment systems. Therefore, specifically AVA_VAN.5
13
was chosen in order to assure that even these attackers cannot successfully attack the TOE.

8 TOE Summary Specification (ASE_TSS)
1
The product overview is given in section 2.1. In the following the Security Features are described and
2
the relation to the security functional requirements is shown.
3
The TOE is equipped with following Security Features to meet the security functional requirements:
4
 SF_DPM Device Phase Management
5
 SF_PS Protection against Snooping
6
 SF_PMA Protection against Modification Attacks
7
 SF_PLA Protection against Logical Attacks
8
 SF_CS Cryptographic Support
9
10
The following description of the Security Features is a complete representation of the TSF.
11
8.1 SF_DPM: Device Phase Management
12
The life cycle of the TOE is split-up in several phases. Chip development and production (phase 2, 3, 4)
13
and final use (phase 4-7) is a rough split-up from TOE point of view. These phases are implemented in
14
the TOE as test mode (phase 3) and user mode (phase 4-7).
15
In addition a chip identification mode exists which is active in all phases. The chip identification data
16
(O.Identification) is stored in a in the not changeable configuration page area and non-volatile
17
memory. In the same area further TOE configuration data is stored. In addition, user initialization data
18
can be stored in the non-volatile memory during the production phase as well. During this first data
19
programming, the TOE is still in the secure environment and in Test Mode.
20
The covered security functional requirement is FAU_SAS.1 “Audit storage”.
21
During start-up of the TOE the decision for one of the various operation modes is taken dependent on
22
phase identifiers. The decision of accessing a certain mode is defined as phase entry protection. The
23
phases follow also a defined and protected sequence. The sequence of the phases is protected by
24
means of authentication.
25
The covered security functional requirements are FMT_LIM.1 “Limited capabilities” and FMT_LIM.2

27
During the production phase (phase 3 and 4) or after the delivery to the customer (phase 5 or phase 6),
28
the TOE provides the possibility to download a user specific encryption key and user code and data
29
into the empty (erased) SOLID FLASH™ NVM memory area as specified by the associated control
30
information of the Flash Loader software. After finishing the load operation, the Flash Loader can be
31
permanently deactivated, so that no further load operation with the Flash Loader is possible. These
32
procedures are defined as phase operation limitation.

8.2 SF_PS: Protection against Snooping
13
Several mechanisms protect the TOE against snooping the design or the user data during operation
14
and even if it is out of operation (power down).
15
The entire design is kept in a non standard way to prevent attacks using standard analysis methods.
16
Important parts of the chip are especially designed to counter leakage or side channel attacks like
17
DPA/SPA or EMA/DEMA. Therefore, even the physical data gaining is difficult to perform, since timing
18
and current consumption is independent of the processed data. In the design a number of
19
components are automatically synthesized and mixed up to disguise an attacker and to make an
20
analysis more difficult.
21
The covered security functional requirement is FPT_PHP.3 “Resistance to physical attack”.
22
A further protective design method used is secure wiring. All security critical wires have been
23
identified and protected by special routing measures against probing. Additionally the wires are
24
embedded into shield lines and used as normal signal lines for operation of the chip to prevent
25
successful probing. This measurement is called “security optimized wiring”.
26
The covered security functional requirements are FPT_PHP.3 “Resistance to physical attack”,
27
FPT_ITT.1 “Basic internal TSF data transfer protection”, FPT_FLS.1 “Failure with preservation of
28
secure state” and FDP_ITT.1 “Basic internal transfer protection”.
29
All contents of the memories RAM, ROM and SOLID FLASH™ NVM of the TOE are encrypted on chip to
30
protect them against data analysis. The external Flash-memory is not encrypted and not a part of the
31
security functional requirements.
32
In addition the data transferred over the memory bus to and from (bi-directional encryption) the CPU,
33
Co-processor (Crypto2304T and SCP), the special SFRs and the peripheral devices (CRC, RNG and
34
Timer) are transported encrypted with an automatically dynamic key change.
35
The encryption of the memory content is done by the MED using a proprietary cryptographic
36
algorithm and a complex key management providing protection against cryptographic analysis
37
attacks. This means that the SOLID FLASH™ NVM, RAM, ROM and the bus are encrypted with module
38
dedicated and dynamic keys. The only key remaining static over the product life cycle is the specific
39
ROM key changing from mask to mask.
40
All security relevant transfer of addresses or data via the peripheral bus is dynamically masked and
41
thus protected against readout and analysis.
42
The function Trash Register Writes can be activated by the user to hide the fact if an register has been
43
written.

8.3 SF_PMA: Protection against Modifying Attacks
7
The TOE is equipped with an error detection code (EDC) for protecting RAM and ROM and an ECC,
8
which is realized in the SOLID FLASH™ NVM. Thus introduced failures are securely detected and, in
9
terms of single bit errors in the SOLID FLASH™ NVM also automatically corrected (FDP_SDI.2). For
10
SOLID FLASH™ NVM in case of more than one bit errors and for RAM in case of any bit errors detected,
11
a security alarm is triggered.
12
In order to prevent accidental bit faults during production in the ROM, over the data stored in ROM an
13
EDC value is calculated (FDP_SDI.1).
14
The covered security functional requirements are FRU_FLT.2 “Limited fault tolerance“, FDP_PHP.3
15
“Resistance to physical attack“, FDP_SDI.1 “Stored data integrity monitoring” and FDP_SDI.2 “Stored
16
data integrity monitoring and action”.
17
If a user tears the card resulting in a power off situation during an SOLID FLASH™ NVM programming
18
operation or if other perturbation is applied, no data or content loss occurs and the TOE restarts
19
power on. The NVM tearing save write functionality covers FDP_SDI.1 “Stored data integrity
20
monitoring” as the new data to be programmed are checked for integrity and correct programming
21
before the page with the old data becomes valid.
22
23
The covered security functional requirement are FPT_PHP.3 “Resistance to physical attack“, since
24
these measures make it difficult to manipulate the write process of the NVM, FPT_FLS.1 “Failure with
25
preservation of secure state“and FDP_SDI.1 “Stored data integrity monitoring”.
26
In the case that a physical manipulation or a physical probing attack is detected, the processing of the
27
TOE is immediately stopped and the TOE enters a secure state called security reset.
28
The covered security functional requirements are FPT_FLS.1 “Failure with preservation of secure
29
state”, FPT_PHP.3 “Resistance to physical attack” and FPT_TST.2 “Subset TOE security testing“.
30
As physical effects or manipulative attacks may also address the program flow of the user software,
31
two watchdog timers each with a check point register function are implemented. This feature allows
32
the user to check the correct processing time and the integrity of the program flow of the user
33
software.
34
The Instruction Stream Signature Checking (ISS) calculates a hash about all executed instructions and
35
automatically checks the correctness of this hash value. If the code execution follows an illegal path
36
an alarm is triggered.
37
Another measure against modifying and perturbation respectively differential fault attacks (DFA) is
38
the implementation of backward calculation in the SCP. By this induced errors are discovered.
39
The covered security functional requirements are FPT_FLS.1 “Failure with preservation of secure
40
state”, FDP_IFC.1 “Subset information flow control”, FPT_ITT.1 “Basic internal transfer protection”,
41

During start up, the TOE performs various configurations and subsystem tests. After the TOE startup
1
has finished, the operating system or application can call the User Mode Security Life Control (UMSLC)
2
test provided by the Resource Management System. The UMSLC checks the alarm lines and/or the
3
different security functions and sensors for correct operation. The test can be triggered by user
4
software during normal operation. As attempts to modify the security features will be detected from
5
the test, the covered security functional requirement is FPT_TST.2 “Subset TOE security testing“.
6
The correct function of the TOE is only given in the specified range of the environmental operating
7
parameters. To prevent an attack exploiting that circumstance the TOE is equipped with a
8
temperature sensor, glitch sensor and backside light detection. The TOE falls into the defined secure
9
state in case of a specified range violation. The defined secure state causes the chip internal reset
10
process. Note that the specified range checking can only work when the TOE is running and can not
11
prevent reverse engineering.

8.4 SF_PLA: Protection against Logical Attacks
19
The memory model of the TOE provides two distinct, independent levels called the privileged and
20
non-privilege level and the possibility to define up to eight memory regions with different access
21
rights enforced by the Management Protection Unit (MPU). This gives the user software the possibility
22
to define different access rights for the regions 0 to 7 for privilege or non-privilege level. In the case of
23
an access violation the MPU will trigger a trap. The policy of setting up the MPU and specifying the
24
memory ranges for the regions (0 to 7) is defined from the user software.
25
The covered security functional requirements are FDP_ACC.1 “Subset access control”, FDP_ACF.1
26
“Security attribute based access control”, FMT_MSA.1 “Management of security attributes”,
27

28
All memories present on the TOE (NVM, ROM, RAM) are encrypted using individual keys assigned by
29
complex key management. In case of security critical error a security alarm is generated and the TOE
30
ends up in a secure state.
31
The covered security functional requirements are FDP_ACF.1 “Security attribute based access
32
control” and FPT_FLS.1 “Failure with preservation of secure state”.

Crypto2304T. If the optional ECC library is not delivered then this TSF is not provided.
26
Note: The TOE can be delivered with the optional PSL library. The PSL library contains a
27
standardized interface to the functions of the ECC library.
28
8.5.7 Toolbox Library
29
The toolbox provides the following basic long integer arithmetic and modular functions in software,
30
supported by the cryptographic coprocessor: Addition, subtraction, division, multiplication,
31
comparison, reduction, modular addition, modular subtraction, modular multiplication, modular
32
inversion and modular exponentiation. No security relevant policy, mechanism or function is
33
supported. The toolbox library is deemed for software developers as support for simplified
34
implementation of long integer and modular arithmetic operations.
35
The toolbox does not cover security functional requirements.

8.5.8 Asymmetric Base Library
1
The asymmetric Base library provides the low level interface to the asymmetric cryptographic
2
coprocessor and has no user available interface. The asymmetric Base library does not provide
3
any security functionality, implements no security mechanism, and does not provide additional
4
specific security functionality. The asymmetric Base library does not cover security functional
5
requirements.
6
8.5.9 Symmetric Crypto Library (SCL)
7
The symmetric crypto Library provides an interface to the SCP for AES and 3DES operations. The
8
SCL contains additional software countermeasures to harden the restance against side channel
9
and fault attacks. The SCL consists of three files “AES.lib”, “DES.lib” and “cipher.lib”. Those
10
library files will only distributes together.
11
The covered security functional requirements are FCS_COP.1/DES_SCL, FSC_COP.1/AES_SCL.
12
8.5.1 Hash Crypto Library (HCL)
13
The hash crypto Library provides an interface to SHA-1 and SHA-2 hash operations. The HCL
14
contains additional software countermeasures to harden the restance against single side channel
15
template attacks. The HCL consists of the files “HCL97-CPU-L90-hash.lib” and “HCL97-CPU-L90-
16
sha.lib”
17
The covered security functional requirements are FCS_COP.1/SHA.
18
19
8.5.2 Platform Support Layer (PSL)
20
The Platform Support Layer (PSL) library is used to provide a standardized interface to the hardware,
21
directly or via the RSA, ECC and SCL lib
22
rary. The provided interfaces are syntactically similar to Windows NT device driver calls. The PSL
23
provides as additional cryptographic operations a MAC calculation with AES and 3DES keys.
24
The covered security functional requirements are FCS_COP.1/DES_PSL, FCS_COP.1/DES_MAC_PSL,
25
FSC_COP.1/AES_PSL, FSC_COP.1/AES_MAC_PSL, FCS_COP.1/RSA_PSL, FSC_COP.1/ECDSH_PSL,

8.5.3 TRNG
29
Random data is essential for cryptography as well as for security mechanisms. The TOE is equipped
30
with a physical True Random Number Generator (TRNG, FCS_RNG.1/HW and FCS_RNG.1/PSL). The
31
random data can be used from the Smartcard Embedded Software and is also used from the security
32
features of the TOE, like masking. The TRNG implements also self testing features. The TRNG fulfils the
33
requirements from the functionality class PTG.2 of [6].
34
The covered security functional requirement is FCS_RNG.1/HW and FCS_RNG.1/PSL “Quality metric
35
for random numbers”, FPT_PHP.3 “Resistance to physical attack”, FDP_ITT.1 “Basic internal transfer
36
protection”, FPT_ITT.1 “Basic internal TSF data transfer protection, FDP_IFC.1 “Subset information
37

Security Functionality
5
The justification and overview of the mapping between security functional requirements (SFR) and
6
the TOE’s security functionality (SF) is given in sections the sections above. The results are shown in
7
Table 21. The security functional requirements are addressed by at least one relating security feature.
8
The various functional requirements are often covered manifold. As described above the
9
requirements ensure that the TOE is checked for correct operating conditions and if a not correctable
10
failure occurs that a stored secure state is achieved, accompanied by data integrity monitoring and
11
actions to maintain the integrity although failures occurred. An overview is given in following table:

8.7 Security Requirements are internally Consistent
3
For this chapter the PP [1] section 6.3.4 can be applied completely.
4
In addition to the discussion in section 6.3 of PP [1] the security functional requirement FCS_COP.1 is
5
introduced. The security functional requirements required to meet the security objectives O.Leak-
6
Inherent, O.Phys-Probing, O.Malfunction, O.Phys-Manipulation and O.Leak-Forced also protect the
7
cryptographic algorithms implemented according to the security functional requirement FCS_COP.1.
8
Therefore, these security functional requirements support the secure implementation and operation
9
of FCS_COP.1.
10
As disturbing, manipulating during or forcing the results of the test checking the security functions
11
after TOE delivery, this security functional requirement FPT_TST.2 has to be protected. An attacker
12
could aim to switch off or disturb certain sensors or filters and preserve the detection of his
13
manipulation by blocking the correct operation of FPT_TST.2. The security functional requirements
14
required to meet the security objectives O.Leak-Inherent, O.Phys-Probing, O.Malfunction, O.Phys-
15
Manipulation and O.Leak-Forced also protect the security functional requirement FPT_TST.2.
16
Therefore, the related security functional requirements support the secure implementation and
17
operation of FPT_TST.2.
18
The requirement FPT_TST.2 allows testing of some security mechanisms by the Smartcard Embedded
19
Software after delivery. In addition, the TOE provides an automated continuous user transparent
20
testing of certain functions.
21
The implemented level concept represents the area based memory access protection enforced by the
22
MPU. As an attacker could attempt to manipulate the privilege level definition as defined and present
23
in the TOE, the functional requirement FDP_ACC.1 and the related other requirements have to be
24
protected themselves. The security functional requirements required to meet the security objectives
25
O.Leak-Inherent, O.Phys-Probing, O.Malfunction, O.Phys-Manipulation and O.Leak-Forced also
26
protect the area based memory access control function implemented according to the security
27
functional requirement described in the security functional requirement FDP_ACC.1 with reference to
28
the Memory Access Control Policy and details given in FDP_ACF.1. Therefore, those security functional
29
requirements support the secure implementation and operation of FDP_ACF.1 with its dependent
30
security functional requirements.

The requirement FDP_SDI.2.1 allows detection of integrity errors of data stored in memory.
1
FDP_SDI.2.2 in addition allows correction of one bit errors or taking further action. Both meet the
2
security objective O.Malfunction. The requirements FRU_FLT.2, FPT_FLS.1, and FDP_ACC.1 which also
3
meet this objective are independent from FDP_SDI.2 since they deal with the observation of the
4
correct operation of the TOE and not with the memory content directly.
