1. SECURITY TARGET INTRODUCTION
1.1 ST Reference
ST Title: AKiS-Pasaport v1.4N Security Target Lite, rev 6,
18.04.2011
This Security Target describes the TOE, intended IT environment (terminal, inspection system,
and basic inspection system), security objectives, security requirements, security functions and
all necessary rationale.
1.1.1 Operation Notation for Functional Requirements
The CC allows several operations to be performed on functional requirements; refinement,
selection, assignment, and iteration. Each of these operations is used in this ST.
The refinement operation is used to add detail to a requirement, and thus further restricts a
requirement. Refinement of security requirements is denoted by the word “refinement” in bold
text and the added/changed words are in bold text. In cases where words from a CC
requirement were deleted, a separate attachment indicates the words that were removed.
The selection operation is used to select one or more options provided by the CC in stating a
requirement.
The assignment operation is used to assign a specific value to an unspecified parameter, such
as the length of a password.
The iteration operation is used when a component is repeated with varying operations. Iterated
functional requirement components are shown with a “/IDENTIFIER” for the components which used
more than once with varying operations.
1.2 TOE Reference
TOE Identification: AKiS-Pasaport version 1.4N
1.3 TOE Overview
1.3.1 TOE definition
AKiS-Pasaport v1.4N is a smart card which is designed to be used as Machine Readable Travel
Document (MRTD). The Target of Evaluation (TOE) is the contactless integrated circuit chip
of machine readable travel document (AKiS-Pasaport) programmed according to the Logical
Data Structure (LDS) and providing the Basic Access Control according to ‘ICAO Doc 9303’.
1.3.2 TOE usage and security features for operational use
The usage and security features are as defined in the MRTD with ICAO Application, Basic
Access Control protection profile:
A State or Organization issues MRTDs to be used by the holder for international travel. The
traveler presents a MRTD to the inspection system to prove his or her identity. The MRTD in
context of this ST contains
(i) visual (eye readable) biographical data and portrait of the holder,

(ii) a separate data summary (MRZ data) for visual and machine reading using
OCR methods in the Machine readable zone (MRZ) and
(iii) data elements on the MRTD’s chip according to LDS for contactless machine reading.
The authentication of the traveler is based on
(i) the possession of a valid MRTD personalized for a holder with the claimed identity as given
on the biographical data page and
(ii) optional biometrics using the reference data stored in the MRTD.
The issuing State or Organization ensures the authenticity of the data of genuine MRTD’s. The
receiving State trusts a genuine MRTD of an issuing State or Organization.
1.3.3 Non-TOE hardware/software/firmware required by the TOE
There is no explicit non-TOE hardware, software or firmware required by the TOE to perform
its claimed security features. The TOE is defined to comprise the chip and the complete
operating system and application. Note, the inlay holding the chip as well as the antenna and the
booklet (holding the printed MRZ) are needed to represent a complete MRTD, nevertheless
these parts are not inevitable for the secure operation of the TOE.

1.4 TOE Description
AKiS v1.4N algorithms and crypto specifications are;
Basic Access Control;
ISO/IEC11770-2 Key Establishment Mechanism 6
3DES CBC as block cipher
Cryptographic checksum ISO/IEC9797-1 MAC Algorithm 3
Active Authentication;
ISO/IEC9796-2 Digital Signature Scheme 1
1.4.1 Physical Scope of TOE
The TOE comprises
• the circuitry of the MRTD’s chip (the integrated circuit, IC): NXP P5CD081
• the IC Embedded Software (AKiS-Pasaport v1.4N OS),
• the MRTD application and
• the MRTD User Manual.
1.4.1.1 MRTD Chip
The integrated circuit of the MRTD’s chip is NXP P5CD081. NXP-P5CD081 has CC EAL 5+

is loaded into the ROM of the NXP chip (P5CD081) during the manufacturing of the IC.
1.4.1.2 AKiS v1.4N Operating System
Smart cards are used as electronic authentication keys, digital signs, GSM cards and bank cards.
Also, they are used as electronic passports and e-government cards such as personal
identification and health care cards.
Basically a smart card consists of 3 main parts:
• Metallic unit on plastic material which is called plastic module (physical plastic card)
• Silicon chip located in the metallic unit on the plastic module. This chip consists of
microprocessor, ROM, RAM, EEPROM and some hardware units
• Operating system (written in ROM and enables the operation of card functions using
hardware units)
From the 3 parts listed above, only the third one is developed by TÜBİTAK-UEKAE. The first
part is developed by a card manufacturer company (who provides the conditions that are
presented in AKiS_TeslimveIsletim document) and the second part is developed by NXP
Company. The second part has EAL 5+ (compatible with BSI0002) certificate. TOE operates
on NXP P5CD081 chip. Chip consists of; 8051 based microprocessor, ROM, EEPROM, RAM,
Advanced Crypto Engine (ACE), Random Number Generator, MMU, UART, Timers and

• File Manager
• Command Interpreter
• Communication Handler
Message is received by UART which is managed by communication handler in TOE. The
message comes in TPDU format which is mentioned above. Incoming TPDU packet is analysed
and block type decision is made by the communication handler. TPDU may include 3 different
types of blocks, named R, S and I block. R and S blocks are used to control the transmission
protocol (ISO 7816-3). I block carries the command which is transmitted to the command
interpreter and executed in TOE. When command execution is finished, communication handler
sends the answer to the reader via UART. If the command is related with the file system,
command interpreter calls the file manager. File manager is responsible for the operations in the
file field which is in the EEPROM. Memory manager is used to open new file, close file, delete
page and attach new page.

1.4.2 Logical Scope of TOE
For this ST the MRTD is viewed as unit of
(a) the physical MRTD as travel document in form of paper, plastic and chip. It presents
visual readable data including (but not limited to) personal data of the MRTD holder
(1) the biographical data on the biographical data page of the passport book,
(2) the printed data in the Machine-Readable Zone (MRZ) and
(3) the printed portrait.
(b) the logical MRTD as data of the MRTD holder stored according to the Logical Data
Structure as specified by ICAO on the contactless integrated circuit. It presents contactless
readable data including (but not limited to) personal data of the MRTD holder
(1) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1),
(2) the digitized portraits (EF.DG2),
(3) the other data according to LDS (EF.DG5 to EF.DG16) and
(4) the Document security object.
The issuing State or Organization implements security features of the MRTD to maintain the
authenticity and integrity of the MRTD and their data. The MRTD as the passport book and the
MRTD’s chip is uniquely identified by the Document Number.
The physical MRTD is protected by physical security measures (e.g. watermark on paper,
security printing), logical (e.g. authentication keys of the MRTD’s chip) and organizational
security measures (e.g. control of materials, personalization procedures). These security
measures include the binding of the MRTD’s chip to the passport book.
The logical MRTD is protected in authenticity and integrity by a digital signature created by the
document signer acting for the issuing State or Organization and the security features of the
MRTD’s chip.
The ICAO defines the baseline security methods Passive Authentication and the optional
advanced security methods Basic Access Control to the logical MRTD, Active Authentication
of the MRTD’s chip, Extended Access Control to and the Data Encryption of additional
sensitive biometrics as optional security measure in the ‘ICAO Doc 9303’. The Passive
Authentication Mechanism and the Data Encryption are performed completely and
independently on the TOE by the TOE environment.
This ST addresses the protection of the logical MRTD
(i) in integrity by writeonly-once access control and by physical means, and
(ii) in confidentiality by the Basic Access Control Mechanism.
(iii) in non-clonability by the Active Authentication Mechanism.
The Basic Access Control is a security feature which is mandatory supported by the TOE. The
inspection system
(i) reads optically the MRTD,
(ii) authenticates itself as inspection system by means of Document Basic Access
Keys.
After successful authentication of the inspection system the MRTD’s chip provides read access
to the logical MRTD by means of private communication (secure messaging) with this
inspection system.

TOE life cycle
The TOE life cycle is described in terms of the four life cycle phases, but TOE actually
comprises of phase 1 and step 3 of phase 2.
Phase 1 “Development”
(Step1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the
IC Dedicated Software and the guidance documentation associated with these TOE
components.
(Step2) The software developer uses the guidance documentation for the integrated circuit and
the guidance documentation for relevant parts of the IC Dedicated Software and develops the
IC Embedded Software (operating system), the MRTD application and the guidance
documentation associated with these TOE components.
The manufacturing documentation of the IC including the IC Dedicated Software and the
Embedded Software in the non-volatile non-programmable memories (ROM) is securely
delivered to the IC manufacturer. The IC Embedded Software in the non-volatile programmable
memories, the MRTD application and the guidance documentation is securely delivered to the
MRTD manufacturer.
Phase 2 “Manufacturing”
(Step3) In a first step the TOE integrated circuit is produced containing the MRTD’s chip
Dedicated Software and the parts of the MRTD’s chip Embedded Software in the non-volatile
non-programmable memories (ROM). The IC manufacturer writes the IC Identification Data
onto the chip to control the IC as MRTD material during the IC manufacturing and the delivery
process to the MRTD manufacturer. The IC is securely delivered from the IC manufacturer to
the MRTD manufacturer.
(Step4) The MRTD manufacturer combines the IC with hardware for the contactless interface
in the passport book.
(Step5) The MRTD manufacturer initializes the MRTD by these steps
(i) configuring the MRTD (choosing hash algorithm SHA-1 or SHA-256 for internal
authenticate, enable attack counter, setting max BAC error number and delay,
setting ATS historical bytes )
(ii) creating the MRTD application and
(iii)equiping MRTD’s chips with pre-personalization Data.
Creation of the application implies the creation of MF and ICAO.DF
The pre-personalized MRTD together with the IC Identifier is securely delivered from the
MRTD manufacturer to the Personalization Agent. The MRTD manufacturer also provides the
relevant parts of the guidance documentation to the Personalization Agent.
Phase 3 “Personalization of the MRTD”
(Step6) The personalization of the MRTD includes
(i) the survey of the MRTD holder’s biographical data,
(ii) the enrolment of the MRTD holder biometric reference data (i.e. the digitized
portraits and the optional biometric reference data),
(iii) the printing of the visual readable data onto the physical MRTD,
(iv) the writing of the TOE User Data and TSF Data into the logical MRTD and
(v) configuration of the TSF.

The step (iv) is performed by the Personalization Agent and includes but is not limited to the
creation of
(i) the digital MRZ data (EF.DG1),
(ii) the digitized portrait (EF.DG2), and
(iii) the Document security object.
The signing of the Document security object by the Document Signer finalizes the
personalization of the genuine MRTD for the MRTD holder. The personalized MRTD (together
with appropriate guidance for TOE use if necessary) is handed over to the MRTD holder for
operational use.
The TSF data (data created by and for the TOE, that might affect the operation of the TOE)
comprise the Manufacturer Authentication Key, the Personalization Agent Authentication Key,
the Basic Access Control Key, the Active Authentication Key, maximum value for attack
counter and BAC error counter, active authentication hash algorithm type (SHA-1 or SHA-256
is chosen).
Phase 4 “Operational Use”
(Step7) The TOE is used as MRTD chip by the traveler and the inspection systems in the
“Operational Use” phase. The user data can be read according to the security policy of the
issuing State or Organization and can be used according to the security policy of the issuing
State but they can never be modified.

2.3 Package Claim
EAL4 augmented with ALC_DVS.2.
2.4 Conformance Rationale
An assurance requirement of EAL4 is required for this type of TOE since it is intended to
defend against sophisticated attacks. In order to provide a meaningful level of assurance that the
TOE provides an adequate level of defense against such attacks, the evaluators should have
access to the low level design and source code. The lowest for which such access is required is
EAL4. The assurance level EAL4 is achievable, since it requires no specialist techniques on the
part of the developer.
EAL4 is augmented with ALC_DVS.2.

3 SECURITY PROBLEM DEFINITION
3.1 Introduction
Assets
The assets to be protected by the TOE include the User Data on the MRTD’s chip.
Logical MRTD Data
The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16 (with different security
needs) and the Document Security Object EF.SOD according to LDS. These data are user data
of the TOE. The EF.COM lists the existing elementary files (EF) with the user data. The
EF.DG1 to EF.DG13 and EF.DG 16 contain personal data of the MRTD holder. The Chip
Authentication Public Key (EF.DG 14) is used by the inspection system for the Chip
Authentication. The EF.SOD is used by the inspection system for Passive Authentication of the
logical MRTD.
The TOE specifies the BAC mechanisms with resistance against enhanced basic attack potential
granting access to
• Logical MRTD standard User Data (i.e. Personal Data) of the MRTD holder (EF.DG1,
EF.DG2, EF.DG5 to EF.DG13, EF.DG16),
• Chip Authentication Public Key in EF.DG14,
• Active Authentication Public Key in EF.DG15,
• Document Security Object (SOD) in EF.SOD,
• Common data in EF.COM
and Active Authentication mechanism.
The TOE prevents read access to sensitive User Data
• Sensitive biometric reference data (EF.DG3, EF.DG4).
A sensitive asset is the following more general one.
Authenticity of the MRTD’s chip
The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the
MRTD holder is used by the traveler to prove his possession of a genuine MRTD.
Subjects
This ST considers the following subjects:
Manufacturer
The generic term for the IC Manufacturer producing the integrated circuit and the MRTD
Manufacturer completing the IC to the MRTD’s chip. The Manufacturer is the default user of
the TOE during the Phase 2 Manufacturing. The TOE does not distinguish between the users IC
Manufacturer and MRTD Manufacturer using this role Manufacturer.
Personalization Agent
The agent is acting on behalf of the issuing State or Organization to personalize the MRTD for
the holder by some or all of the following activities
(i) establishing the identity the holder for the biographic data in the MRTD,
(ii) enrolling the biometric reference data of the MRTD holder i.e. the portrait, the encoded
finger image(s) and/or the encoded iris image(s)

(iii) writing these data on the physical and logical MRTD for the holder as defined for
global, international and national interoperability,
(iv) writing the initial TSF data and
(v) signing the Document Security Object.
Terminal
A terminal is any technical system communicating with the TOE through the contactless
interface.
Inspection system (IS)
A technical system used by the border control officer of the receiving State
(i) examining an MRTD presented by the traveler and verifying its authenticity and
(ii) verifying the traveler as MRTD holder.
The Basic Inspection System (BIS)
(i) contains a terminal for the contactless communication with the MRTD’s chip,
(ii) implements the terminals part of the Basic Access Control Mechanism and
(iii) gets the authorization to read the logical MRTD under the Basic Access Control by
optical reading the MRTD or other parts of the passport book providing this
information.
MRTD Holder
The rightful holder of the MRTD for whom the issuing State or Organization personalized the
MRTD.
Traveler
Person presenting the MRTD to the inspection system and claiming the identity of the MRTD
holder.
Attacker
A threat agent trying
(i) to identify and to trace the movement of the MRTD’s chip remotely (i.e. without
knowing or optically reading the printed MRZ data),
(ii) to read or to manipulate the logical MRTD without authorization, or
(iii) to forge a genuine MRTD.
An impostor is attacking the inspection system as TOE IT environment independent on using a
genuine, counterfeit or forged MRTD. Therefore the impostor may use results of successful
attacks against the TOE but the attack itself is not relevant for the TOE.
3.2 Assumptions
The assumptions describe the security aspects of the environment in which the TOE will be
used or is intended to be used.
A.MRTD_Manufact MRTD manufacturing on steps 4 to 6
It is assumed that appropriate functionality testing of the MRTD is used. It is assumed that
security procedures are used during all manufacturing and test operations to maintain
confidentiality and integrity of the MRTD and of its manufacturing and test data (to prevent any
possible copy, modification, retention, theft or unauthorized use).

A.MRTD_Delivery MRTD delivery during steps 4 to 6
Procedures shall guarantee the control of the TOE delivery and storage process and
conformance to its objectives:
- Procedures shall ensure protection of TOE material/information under delivery and storage.
- Procedures shall ensure that corrective actions are taken in case of improper operation in the
delivery process and storage.
- Procedures shall ensure that people dealing with the procedure for delivery have got the
required skill.
A.Pers_Agent Personalization of the MRTD’s chip
The Personalization Agent ensures the correctness of
(i) the logical MRTD with respect to the MRTD holder,
(ii) the Document Basic Access Keys,
(iii) the Chip Authentication Public Key (EF.DG14) if stored on the MRTD’s chip, and
(iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip). The
Personalization Agent signs the Document Security Object.
The Personalization Agent bears the Personalization Agent Authentication to authenticate
himself to the TOE by symmetric cryptographic mechanisms.
A.Insp_Sys Inspection Systems for global interoperability
The Inspection System is used by the border control officer of the receiving State
(i) examining an MRTD presented by the traveler and verifying its authenticity and
(ii) verifying the traveler as MRTD holder.
The Basic Inspection System for global interoperability
(i) includes the Country Signing Public Key and the Document Signer Public Key of each
issuing State or Organization, and
(ii) implements the terminal part of the Basic Access Control.
The Basic Inspection System reads the logical MRTD under Basic Access Control and
performs the Passive Authentication to verify the logical MRTD.
A.BAC-Keys Cryptographic quality of Basic Access Control Keys
The Document Basic Access Control Keys being generated and imported by the issuing State or
Organization have to provide sufficient cryptographic strength. As a consequence of the ‘ICAO
Doc 9303’ , the Document Basic Access Control Keys are derived from a defined subset of the
individual printed MRZ data. It has to be ensured that these data provide sufficient entropy to
withstand any attack based on the decision that the inspection system has to derive Document
Access Keys from the printed MRZ data with enhanced basic attack potential.
3.3 Threats
This section describes the threats to be averted by the TOE independently or in collaboration
with its IT environment. These threats result from the TOE method of use in the operational
environment and the assets stored in or protected by the TOE.
The TOE in collaboration with its IT environment shall avert the threats as specified below.
T.Chip_ID Identification of MRTD’s chip
Adverse action: An attacker trying to trace the movement of the MRTD by identifying remotely
the MRTD’s chip by establishing or listening to communications through the contactless
communication interface.

Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ
data printed on the MRTD data page in advance
Asset: Anonymity of user,
T.Skimming Skimming the logical MRTD
Adverse action: An attacker imitates an inspection system trying to establish a communication
to read the logical MRTD or parts of it via the contactless communication channel of the TOE.
Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ
data printed on the MRTD data page in advance
Asset: confidentiality of logical MRTD data
T.Eavesdropping Eavesdropping to the communication between TOE and
inspection system
Adverse action: An attacker is listening to an existing communication between the MRTD’s
chip and an inspection system to gain the logical MRTD or parts of it. The inspection system
uses the MRZ data printed on the MRTD data page but the attacker does not know these data in
advance.
Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ
data printed on the MRTD data page in advance
Asset: confidentiality of logical MRTD data
T.Forgery Forgery of data on MRTD’s chip
Adverse action: An attacker alters fraudulently the complete stored logical MRTD or any part
of it including its security related data in order to deceive on an inspection system by means of
the changed MRTD holder’s identity or biometric reference data. This threat comprises several
attack scenarios of MRTD forgery. The attacker may alter the biographical data on the
biographical data page of the passport book, in the printed MRZ and in the digital MRZ to
claim another identity of the traveler. The attacker may alter the printed portrait and the
digitized portrait to overcome the visual inspection of the inspection officer and the automated
biometric authentication mechanism by face recognition. The attacker may alter the biometric
reference data to defeat automated biometric authentication mechanism of the inspection
system. The attacker may combine data groups of different logical MRTDs to create a new
forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference
finger data read from the logical MRTD of a traveler into another MRTD’s chip leaving their
digital MRZ unchanged to claim the identity of the holder this MRTD. The attacker may also
copy the complete unchanged logical MRTD to another contactless chip.
Threat agent: having enhanced basic attack potential, being in possession of one or more
legitimate MRTDs
Asset: authenticity of logical MRTD data
The TOE shall avert the threats as specified below.
T.Abuse-Func Abuse of Functionality
Adverse action: An attacker may use functions of the TOE which shall not be used in the phase
“Operational Use” in order
(i) to manipulate User Data,
(ii) to manipulate (explore, bypass, deactivate or change) security features or functions of
the TOE or
(iii) to disclose or to manipulate TSF Data.
This threat addresses the misuse of the functions for the initialization and the personalization in
the operational state after delivery to MRTD holder.

Threat agent: having enhanced basic attack potential, being in possession of a legitimate
MRTD
Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF.
T.Information_Leakage Information Leakage from MRTD’s chip
Adverse action: An attacker may exploit information which is leaked from the TOE during its
usage in order to disclose confidential TSF data. The information leakage may be inherent in
the normal operation or caused by the attacker.
Leakage may occur through emanations, variations in power consumption, I/O characteristics,
clock frequency, or by changes in processing time requirements. This leakage may be
interpreted as a covert channel transmission but is more closely related to measurement of
operating parameters, which may be derived either from measurements of the contactless
interface (emanation) or direct measurements (by contact to the chip still available even for a
contactless chip) and can then be related to the specific operation being performed. Examples
are the Differential Electromagnetic Analysis (DEMA) and the Differential Power Analysis
(DPA). Moreover the attacker may try actively to enforce information leakage by fault injection
(e.g. Differential Fault Analysis).
Threat agent: having enhanced basic attack potential, being in possession of a legitimate
MRTD
Asset: confidentiality of logical MRTD and TSF data
T.Phys-Tamper Physical Tampering
Adverse action: An attacker may perform physical probing of the MRTD’s chip in order
(i) to disclose TSF Data or
(ii) to disclose/reconstruct the MRTD’s chip Embedded Software.
An attacker may physically modify the MRTD’s chip in order to
(i) modify security features or functions of the MRTD’s chip,
(ii) modify security functions of the MRTD’s chip Embedded Software,
(iii) modify User Data or
(iv) to modify TSF data.
The physical tampering may be focused directly on the disclosure or manipulation of TOE User
Data (e.g. the biometric reference data for the inspection system) or TSF Data (e.g.
authentication key of the MRTD’s chip) or indirectly by preparation of the TOE to following
attack methods by modification of security features (e.g. to enable information leakage through
power analysis). Physical tampering requires direct interaction with the MRTD’s chip internals.
Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may
be used. Before that, the hardware security mechanisms and layout characteristics need to be
identified.
Determination of software design including treatment of User Data and TSF Data may also be a
pre-requisite. The modification may result in the deactivation of a security function. Changes of
circuitry or data can be permanent or temporary.
Threat agent: having enhanced basic attack potential, being in possession of a legitimate
MRTD
Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF
T.Malfunction Malfunction due to Environmental Stress
Adverse action: An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded
Software by applying environmental stress in order to
(i) deactivate or modify security features or functions of the TOE or

4 SECURITY OBJECTIVES
This part describes the security objectives for the TOE and the security objectives for the TOE
environment. The security objectives for the TOE environment are separated into security
objectives for the development and production environment and security objectives for the
operational environment.
4.1 Security Objectives for the TOE
This section describes the security objectives for the TOE addressing the aspects of identified
threats to be countered by the TOE and organizational security policies to be met by the TOE.
OT.AC_Pers Access Control for Personalization of logical MRTD
The TOE must ensure that the logical MRTD data in EF.DG1 to EF.DG16, the Document
security object according to LDS and the TSF data can be written by authorized Personalization
Agents only. The logical MRTD data in EF.DG1 to EF.DG16 and the TSF data may be written
only during and cannot be changed after its personalization. The Document security object can
be updated by authorized Personalization Agents if data in the data groups EF.DG3 to EF.DG16
are added.
OT.Data_Int Integrity of personal data
The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against
physical manipulation and unauthorized writing. The TOE must ensure that the inspection
system is able to detect any modification of the transmitted logical MRTD data.
OT.Data_Conf Confidentiality of personal data
The TOE must ensure the confidentiality of the logical MRTD data groups EF.DG1 to
EF.DG16. Read access to EF.DG1 to EF.DG16 is granted to terminals successfully
authenticated as Personalization Agent. Read access to EF.DG1, EF.DG2 and EF.DG5 to
EF.DG16 is granted to terminals successfully authenticated as Basic Inspection System. The
Basic Inspection System shall authenticate itself by means of the Basic Access Control based
on knowledge of the Document Basic Access Key. The TOE must ensure the confidentiality of
the logical MRTD data during their transmission to the Basic Inspection System.
The traveler grants the authorization for reading the personal data in EF.DG1, EF.DG2 and
EF.DG5 to EF.DG16 to the inspection system by presenting the MRTD. The MRTD’s chip
shall provide read access to these data for terminals successfully authenticated by means of the
Basic Access Control based on knowledge of the Document Basic Access Keys.
The security objective OT.Data_Conf requires the TOE to ensure the strength of the security
function Basic Access Control Authentication. The Document Basic Access Keys are derived
from the MRZ data defined by the TOE environment and are loaded into the TOE by the
Personalization Agent. Therefore the sufficient quality of these keys has to result from the MRZ
data’s entropy. Any attack based on decision of the ‘ICAO Doc 9303’ that the inspection
system derives Document Basic Access is ensured by OE.BAC-Keys. Note that the
authorization for reading the biometric data in EF.DG3 and EF.DG4 is only granted after
successful Enhanced Access Control not covered by this protection profile. Thus the read
access must be prevented even in case of a successful BAC Authentication.
OT.Identification Identification and Authentication of the TOE
The TOE must provide means to store IC Identification and Pre-Personalization Data in its
nonvolatile memory. The IC Identification Data must provide a unique identification of the IC

during Phase 2 “Manufacturing” and Phase 3 “Personalization of the MRTD”. The storage of
the Pre- Personalization data includes writing of the Personalization Agent Key(s). In Phase 4
“Operational Use” the TOE shall identify itself only to a successful authenticated Basic
Inspection System or Personalization Agent.
The TOE security objective OT.Identification addresses security features of the TOE to support
the life cycle security in the manufacturing and personalization phases. The IC Identification
Data are used for TOE identification in Phase 2 “Manufacturing” and for traceability and/or to
secure shipment of the TOE from Phase 2 “Manufacturing” into the Phase 3 “Personalization of
the MRTD”. The OT.Identification addresses security features of the TOE to be used by the
TOE manufacturing. In the Phase 4 “Operational Use” the TOE is identified by the Document
Number as part of the printed and digital MRZ. The OT.Identification forbids the output of any
other IC (e.g. integrated circuit card serial number ICCSN) or MRTD identifier through the
contactless interface before successful authentication as Basic Inspection System or as
Personalization Agent.
The following TOE security objectives address the protection provided by the MRTD’s chip
independent of the TOE environment.
OT.Prot_Abuse-Func Protection against Abuse of Functionality
After delivery of the TOE to the MRTD Holder, the TOE must prevent the abuse of test and
support functions that may be maliciously used to
(i) disclose critical User Data,
(ii) manipulate critical User Data of the IC Embedded Software,
(iii) manipulate Soft-coded ICEmbedded Software or
(iv) bypass, deactivate, change or explore security features or functions of the TOE.
Details of the relevant attack scenarios depend, for instance, on the capabilities of the Test
Features provided by the IC Dedicated Test Software which are not specified here.
OT.Prot_Inf_Leak Protection against Information Leakage
The TOE must provide protection against disclosure of confidential TSF data stored and/or
processed in the MRTD’s chip
• by measurement and analysis of the shape and amplitude of signals or the time between
events found by measuring signals on the electromagnetic field, power consumption,
clock, or I/O lines and
• by forcing a malfunction of the TOE and/or
• by a physical manipulation of the TOE.
This objective pertains to measurements with subsequent complex signal
processing due to normal operation of the TOE or operations enforced by an attacker. Details
correspond to an analysis of attack scenarios which is not given here.
OT.Prot_Phys-Tamper Protection against Physical Tampering
The TOE must provide protection of the confidentiality and integrity of the User Data, the TSF
Data, and the MRTD’s chip Embedded Software. This includes protection against attacks with
enhanced-basic attack potential by means of
• measuring through galvanic contacts which is direct physical probing on the chips
surface except on pads being bonded (using standard tools for measuring voltage and
current) or
• measuring not using galvanic contacts but other types of physical interaction between
charges (using tools used in solid-state physics research and IC failure analysis)

• manipulation of the hardware and its security features, as well as controlled
manipulation of memory contents (User Data, TSF Data) with a prior
• reverse-engineering to understand the design and its properties and functions.
OT.Prot_Malfunction Protection against Malfunctions
The TOE must ensure its correct operation. The TOE must prevent its operation outside the
normal operating conditions where reliability and secure operation has not been proven or
tested. This is to prevent errors. The environmental conditions may include external energy
(esp. electromagnetic) fields, voltage (on any contacts), clock frequency, or temperature.
A malfunction of the TOE may also be caused using a direct interaction with elements on the
chip surface. This is considered as being a manipulation (refer to the objective OT.Prot_Phys-
Tamper) provided that detailed knowledge about the TOE´s internals.
4.2 Security Objectives for the Operational Environment
Issuing State or Organization
The issuing State or Organization will implement the following security objectives of the TOE
environment.
OE.MRTD_Manufact Protection of the MRTD Manufacturing
Appropriate functionality testing of the TOE shall be used in step 4 to 6. During all
manufacturing and test operations, security procedures shall be used through phases 4, 5 and 6
to maintain confidentiality and integrity of the TOE and its manufacturing and test data.
OE.MRTD_ Delivery Protection of the MRTD delivery
Procedures shall ensure protection of TOE material/information under delivery including the
following objectives:
• non-disclosure of any security relevant information,
• identification of the element under delivery,
• meet confidentiality rules (confidentiality level, transmittal form, reception
acknowledgment),
• physical protection to prevent external damage,
• secure storage and handling procedures (including rejected TOE’s),
• traceability of TOE during delivery including the following parameters:
• origin and shipment details,
• reception, reception acknowledgement,
• location material/information.
Procedures shall ensure that corrective actions are taken in case of improper operation in the
delivery process (including if applicable any non-conformance to the confidentiality
convention) and highlight all non-conformance to this process. Procedures shall ensure that
people (shipping department, carrier, reception department) dealing with the procedure for
delivery have got the required skill, training and knowledge to meet the procedure requirements
and be able to act fully in accordance with the above expectations.
OE.Personalization Personalization of logical MRTD
The issuing State or Organization must ensure that the Personalization Agents acting on behalf
of the issuing State or Organization
(i) establish the correct identity of the holder and create biographical data for the MRTD,

(ii) enroll the biometric reference data of the MRTD holder i.e. the portrait, the encoded
finger image(s) and/or the encoded iris image(s) and
(iii) personalize the MRTD for the holder together with the defined physical and logical
security measures to protect the confidentiality and integrity of these data.
OE.Pass_Auth_Sign Authentication of logical MRTD by Signature
The issuing State or Organization must
(i) generate a cryptographic secure Country Signing CA Key Pair,
(ii) ensure the secrecy of the Country Signing CA Private Key and sign Document Signer
Certificates in a secure operational environment, and
(iii) distribute the Certificate of the
Country Signing CA Public Key to receiving States and Organizations maintaining its
authenticity and integrity. The issuing State or Organization must
(i) generate a cryptographic secure Document Signer Key Pair and ensure the secrecy of
the Document Signer Private Keys,
(ii) sign Document Security Objects of genuine MRTD in a secure operational environment
only and
(iii) distribute the Certificate of the Document Signer Public Key to receiving States and
Organizations. The digital signature in the Document Security Object relates all data
in the data in EF.DG1 to EF.DG16 if stored in the LDS.
OE.BAC-Keys Cryptographic quality of Basic Access Control Keys
The Document Basic Access Control Keys being generated and imported by the issuing State or
Organization have to provide sufficient cryptographic strength. As a consequence of the ‘ICAO
Doc 9303’ the Document Basic Access Control Keys are derived from a defined subset of the
individual printed MRZ data. It has to be ensured that these data provide sufficient entropy to
withstand any attack based on the decision that the inspection system has to derive Document
Basic Access Keys from the printed MRZ data with enhanced basic attack potential.
Receiving State or Organization
The receiving State or Organization will implement the following security objectives of the
TOE environment.
OE.Exam_MRTD Examination of the MRTD passport book
The inspection system of the receiving State or Organization must examine the MRTD
presented by the traveler to verify its authenticity by means of the physical security measures
and to detect any manipulation of the physical MRTD. The Basic Inspection System for global
interoperability
(i) includes the Country Signing Public Key and the Document Signer Public Key of each
issuing State or Organization, and
(ii) implements the terminal part of the Basic Access Control.
OE.Passive_Auth_Verif Verification by Passive Authentication
The border control officer of the receiving State uses the inspection system to verify the traveler
as MRTD holder. The inspection systems must have successfully verified the signature of
Document Security Objects and the integrity data elements of the logical MRTD before they are
used. The receiving States and Organizations must manage the Country Signing Public Key and
the Document Signer Public Key maintaining their authenticity and availability in all inspection
systems.
OE.Prot_Logical_MRTD Protection of data from the logical MRTD

(ii) the access control for the user data and TSF data as described by the security objective
OT.AC_Pers “Access Control for Personalization of logical MRTD”.
Note the manufacturer equips the TOE with the Personalization Agent Key(s) according to
OT.Identification “Identification and Authentication of the TOE”. The security objective
OT.AC_Pers limits the management of TSF data and management of TSF to the
Personalization Agent.
The OSP P.Personal_Data “Personal data protection policy” requires the TOE
(i) to support the protection of the confidentiality of the logical MRTD by means of the
Basic Access Control and
(ii) enforce the access control for reading as decided by the issuing State or Organization.
This policy is implemented by the security objectives OT.Data_Int “Integrity of personal data”
describing the unconditional protection of the integrity of the stored data and during
transmission.
The security objective OT.Data_Conf “Confidentiality of personal data” describes the
protection of the confidentiality.
The threat T.Chip_ID “Identification of MRTD’s chip” addresses the trace of the MRTD
movement by identifying remotely the MRTD’s chip through the contactless communication
interface. This threat is countered as described by the security objective OT.Identification by
Basic Access Control using sufficiently strong derived keys as required by the security
objective for the environment OE.BAC-Keys.
The threat T.Skimming “Skimming digital MRZ data or the digital portrait” and
T.Eavesdropping “Eavesdropping to the communication between TOE and inspection system”
address the reading of the logical MRTD trough the contactless interface or listening the
communication between the MRTD’s chip and a terminal. This threat is countered by the
security objective OT.Data_Conf “Confidentiality of personal data” through Basic Access
Control using sufficiently strong derived keys as required by the security objective for the
environment OE.BAC-Keys.
The threat T.Forgery “Forgery of data on MRTD’s chip” addresses the fraudulent alteration of
the complete stored logical MRTD or any part of it. The security objective OT.AC_Pers
“Access Control for Personalization of logical MRTD“ requires the TOE to limit the write
access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization).
The TOE will protect the integrity of the stored logical MRTD according the security objective
OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against
Physical Tampering”. The examination of the presented MRTD passport book according to
OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book
does not contain a sensitive contactless chip which may present the complete unchanged logical
MRTD. The TOE environment will detect partly forged logical MRTD data by means of digital
signature which will be created according to OE.Pass_Auth_Sign “Authentication of logical
MRTD by Signature” and verified by the inspection system according to
OE.Passive_Auth_Verif “Verification by Passive Authentication”.
The threat T.Abuse-Func “Abuse of Functionality” addresses attacks using the MRTD’s chip
as production material for the MRTD and misuse of the functions for personalization in the
operational state after delivery to MRTD holder to disclose or to manipulate the logical MRTD.

This threat is countered by OT.Prot_Abuse-Func “Protection against Abuse of Functionality”.
Additionally this objective is supported by the security objective for the TOE environment:
OE.Personalization “Personalization of logical MRTD” ensuring that the TOE security
functions for the initialization and the personalization are disabled and the security functions for
the operational state after delivery to MRTD holder are enabled according to the intended use
of the TOE.
The threats T.Information_Leakage “Information Leakage from MRTD’s chip”, T.Phys-
Tamper “Physical Tampering” and T.Malfunction “Malfunction due to Environmental Stress”
are typical for integrated circuits like smart cards under direct attack with high attack potential.
The protection of the TOE against these threats is addressed by the directly related security
objectives OT.Prot_Inf_Leak “Protection against Information Leakage”, OT.Prot_Phys-
Tamper “Protection against Physical Tampering” and OT.Prot_Malfunction “Protection

5 EXTENDED COMPONENTS DEFINITION
This ST does not define extended components. The extended components defined in PP
“Machine Readable Travel Document with „ICAO Application”, Basic Access Control” are
used. These extended components are FAU_SAS, FCS_RND, FMT_LIM and FPT_EMSEC,
and defined in the PP as given below.
5.1 Definition of the Family FAU_SAS
To define the security functional requirements of the TOE a sensitive family (FAU_SAS) of the
Class FAU (Security Audit) is defined here. This family describes the functional requirements
for the storage of audit data. It has a more general approach than FAU_GEN, because it does
not necessarily require the data to be generated by the TOE itself and because it does not give
specific details of the content of the audit records.
The family “Audit data storage (FAU_SAS)” is specified as follows.
FAU_SAS Audit data storage
Family behavior
This family defines functional requirements for the storage of audit data.
Component leveling
FAU_SAS.1: Requires the TOE to provide the possibility to store audit data.
Management: FAU_SAS.1
There are no management activities foreseen.
Audit: FAU_SAS.1
There are no actions defined to be auditable.
FAU_SAS.1 Audit storage
Hierarchical to: No other components.
Dependencies: No dependencies.
FAU_SAS.1.1 The TSF shall provide [assignment: authorized users] with the capability to
store [assignment: list of audit information] in the audit records.
5.2 Definition of the Family FCS_RND
To define the IT security functional requirements of the TOE a sensitive family (FCS_RND) of
the Class FCS (cryptographic support) is defined here. This family describes the functional
requirements for random number generation used for cryptographic purposes. The component
FCS_RND is not limited to generation of cryptographic keys unlike the component
FCS_CKM.1. The similar component FIA_SOS.2 is intended for non-cryptographic use.
The family “Generation of random numbers (FCS_RND)” is specified as follows.

This family defines quality requirements for the generation of random numbers which are
intended to be used for cryptographic purposes.
Component leveling:
FCS_RND.1: Generation of random numbers requires that random numbers meet a defined
quality metric.
Management: FCS_RND.1
There are no management activities foreseen.
Audit: FCS_RND.1
There are no actions defined to be auditable.
FCS_RND.1 Quality metric for random numbers
Hierarchical to: No other components.
Dependencies: No dependencies.
FCS_RND.1.1 The TSF shall provide a mechanism to generate random numbers that meet
[assignment: a defined quality metric].
5.3 Definition of the Family FMT_LIM
The family FMT_LIM describes the functional requirements for the Test Features of the TOE.
The new functional requirements were defined in the class FMT because this class addresses
the management of functions of the TSF. The examples of the technical mechanism used in the
TOE show that no other class is appropriate to address the specific issues of preventing the
abuse of functions by limiting the capabilities of the functions and by limiting their availability.
The family “Limited capabilities and availability (FMT_LIM)” is specified as follows.
FMT_LIM Limited capabilities and availability
Family behavior
This family defines requirements that limit the capabilities and availability of functions in a
combined manner. Note that FDP_ACF restricts the access to functions whereas the Limited
capability of this family requires the functions themselves to be designed in a specific manner.
Component leveling:
FMT_LIM.1: Limited capabilities requires that the TSF is built to provide only the
capabilities (perform action, gather information) necessary for its genuine purpose.
FMT_LIM.2: Limited availability requires that the TSF restrict the use of functions (refer to
Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or by
disabling functions in a specific phase of the TOE’s lifecycle.
Management: FMT_LIM.1, FMT_LIM.2
There are no management activities foreseen.
Audit: FMT_LIM.1, FMT_LIM.2

There are no actions defined to be auditable.
To define the IT security functional requirements of the TOE a sensitive family (FMT_LIM) of
the Class FMT (Security Management) is defined here. This family describes the functional
requirements for the Test Features of the TOE. The new functional requirements were defined
in the class FMT because this class addresses the management of functions of the TSF. The
examples of the technical mechanism used in the TOE show that no other class is appropriate to
address the specific issues of preventing the abuse of functions by limiting the capabilities of
the functions and by limiting their availability.
The TOE Functional Requirement “Limited capabilities (FMT_LIM.1)” is specified as follows.
FMT_LIM.1 Limited capabilities
Hierarchical to: No other components.
Dependencies: FMT_LIM.2 Limited availability.
FMT_LIM.1.1 The TSF shall be designed in a manner that limits their capabilities so that in
conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced
[assignment: Limited capability and availability policy].
The TOE Functional Requirement “Limited availability (FMT_LIM.2)” is specified as follows.
FMT_LIM.2 Limited availability
Hierarchical to: No other components.
Dependencies: FMT_LIM.1 Limited capabilities.
FMT_LIM.2.1 The TSF shall be designed in a manner that limits their availability so that in
conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced
[assignment: Limited capability and availability policy].
The functional requirements FMT_LIM.1 and FMT_LIM.2 assume that there are two types of
mechanisms (limited capabilities and limited availability) which together shall provide
protection in order to enforce the policy. This also allows that
(i) the TSF is provided without restrictions in the product in its user environment but its
capabilities are so limited that the policy is enforced
or conversely
(ii) the TSF is designed with test and support functionality that is removed from, or disabled
in, the product prior to the Operational Use Phase.
The combination of both requirements shall enforce the policy.
5.4 Definition of the Family FPT_EMSEC
The sensitive family FPT_EMSEC (TOE Emanation) of the Class FPT (Protection of the TSF)
is defined here to describe the IT security functional requirements of the TOE. The TOE shall
prevent attacks against the TOE and other secret data where the attack is based on external
observable physical phenomena of the TOE. Examples of such attacks are evaluation of TOE’s
electromagnetic radiation, simple power analysis (SPA), differential power analysis (DPA),
timing attacks, etc. This family describes the functional requirements for the limitation of
intelligible emanations which are not directly addressed by any other component of CC part 2.
The family “TOE Emanation (FPT_EMSEC)” is specified as follows.

The TOE shall meet the requirement “Timing of identification (FIA_UID.1)” as specified
below (Common Criteria Part 2).
FIA_UID.1 Timing of identification
Hierarchical to: No other components.
Dependencies: No dependencies.
FIA_UID.1.1 The TSF shall allow
1. to read the Initialization Data in Phase 2 “Manufacturing”,
2. to read the random identifier in Phase 3 “Personalization of the MRTD”,
3. to read the random identifier in Phase 4 “Operational Use”22
on behalf of the user to be performed before the user is identified.
FIA_UID.1.2 The TSF shall require each user to be successfully identified before allowing any
other TSF-mediated actions on behalf of that user.
The IC manufacturer and the MRTD manufacturer write the Initialization Data and/or Pre-
personalization Data in the audit records of the IC during the Phase 2 “Manufacturing”. The
audit records can be written only in the Phase 2 Manufacturing of the TOE. At this time the
Manufacturer is the only user role available for the TOE. The MRTD manufacturer may create
the user role Personalization Agent for transition from Phase 2 to Phase 3 “Personalization of
the MRTD”. The users in role Personalization Agent identify themselves by means of selecting
the authentication key. After personalization in the Phase 3 (i.e. writing the digital MRZ and the
Document Basic Access Keys) the user role Basic Inspection System is created by writing the
Document Basic Access Keys. The Basic Inspection System is identified as default user after
power up or reset of the TOE i.e. the TOE will use the Document Basic Access Key to
authenticate the user as Basic Inspection System.
In the “Operational Use” phase the MRTD must not allow anybody to read the ICCSN, the
MRTD identifier or any other unique identification before the user is authenticated as Basic
Inspection System (cf. T.Chip_ID). Note that the terminal and the MRTD’s chip use a
(randomly chosen) identifier for the communication channel to allow the terminal to
communicate with more then one RFID. If this identifier is randomly selected it will not violate
the OT.Identification. If this identifier is fixed the ST writer should consider the possibility to
misuse this identifier to perform attacks addressed by T.Chip_ID.

The TOE shall meet the requirement “Timing of authentication (FIA_UAU.1)” as specified
below (Common Criteria Part 2).
FIA_UAU.1 Timing of authentication
Hierarchical to: No other components.
Dependencies: FIA_UID.1 Timing of identification.
FIA_UAU.1.1 The TSF shall allow
1. to read the Initialization Data in Phase 2 “Manufacturing”,
2. to read the random identifier in Phase 3 “Personalization of the MRTD”,
3. to read the random identifier in Phase 4 “Operational Use”23
on behalf of the user to be performed before the user is authenticated.
FIA_UAU.1.2 The TSF shall require each user to be successfully authenticated before allowing
any other TSF-mediated actions on behalf of that user.
The Basic Inspection System and the Personalization Agent authenticate themselves.
The TOE shall meet the requirements of “Single-use authentication mechanisms
(FIA_UAU.4)” as specified below (Common Criteria Part 2).
FIA_UAU.4 Single-use authentication mechanisms - Single-use authentication of the
Terminal by the TOE
Hierarchical to: No other components.
Dependencies: No dependencies.
FIA_UAU.4.1 The TSF shall prevent reuse of authentication data related to
1. Basic Access Control Authentication Mechanism,
2. Authentication Mechanism based on [Triple-DES]24
.
FIA_UAU.4.1/AA The TSF shall prevent reuse of authentication data related to Active
Authentication Mechanism,
The authentication mechanisms may use either a challenge freshly and randomly generated by
the TOE to prevent reuse of a response generated by a terminal in a successful authentication
attempt. However, the authentication of Personalisation Agent may rely on other mechanisms
ensuring protection against replay attacks, such as the use of an internal counter as a diversifier.
The Basic Access Control Mechanism is a mutual device authentication mechanism defined in
[6]. In the first step the terminal authenticates itself to the MRTD’s chip and the MRTD’s chip
authenticates to the terminal in the second step. In this second step the MRTD’s chip provides
the terminal with a challenge-response-pair which allows a unique identification of the
MRTD’s chip with some probability depending on the entropy of the Document Basic Access
Keys. Therefore the TOE shall stop further communications if the terminal is not successfully
authenticated in the first step of the protocol to fulfill the security objective OT.Identification
and to prevent T.Chip_ID.

The TOE shall meet the requirement “Multiple authentication mechanisms (FIA_UAU.5)” as
specified below (Common Criteria Part 2).
FIA_UAU.5 Multiple authentication mechanisms
Hierarchical to: No other components.
Dependencies: No dependencies.
FIA_UAU.5.1 The TSF shall provide
1. Basic Access Control Authentication Mechanism
2. Symmetric Authentication Mechanism based on [Triple-DES] 25
to support user authentication.
FIA_UAU.5.1/AA The TSF shall provide
Active Authentication Mechanism based on [RSASSA-PSS]
The TOE shall meet the requirement “Re-authenticating (FIA_UAU.6)” as specified below
(Common Criteria Part 2).

Hierarchical to: No other components.
Dependencies: No dependencies.
FIA_UAU.6.1 The TSF shall re-authenticate the user under the conditions each command sent
to the TOE during a BAC mechanism based communication after successful authentication of
the terminal with Basic Access Control Authentication Mechanism27
.
The Basic Access Control Mechanism specified in [6] includes the secure messaging for all
commands exchanged after successful authentication of the Inspection System. The TOE
checks by secure messaging in MAC_ENC mode each command based on Retail-MAC
whether it was sent by the successfully authenticated terminal (see FCS_COP.1/MAC for
further details). The TOE does not execute any command with incorrect message authentication
code. Therefore the TOE re-authenticates the user for each received command and accepts only
those commands received from the previously authenticated BAC user.
The TOE shall meet the requirement “Authentication failure handling (FIA_AFL.1)” as
specified below (Common Criteria Part 2).

conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced:
Deploying Test Features after TOE Delivery does not allow
1. User Data to be disclosed or manipulated
2. TSF data to be disclosed or manipulated
3. software to be reconstructed and
4. substantial information about construction of TSF to be gathered which may enable
other attacks
The TOE shall meet the requirement “Limited availability (FMT_LIM.2)” as specified below
(Common Criteria Part 2 extended).
FMT_LIM.2 Limited availability
Hierarchical to: No other components.
Dependencies: FMT_LIM.1 Limited capabilities.
FMT_LIM.2.1 The TSF shall be designed in a manner that limits their availability so that
in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced:
Deploying Test Features after TOE Delivery does not allow
1. User Data to be disclosed or manipulated,
2. TSF data to be disclosed or manipulated
3. software to be reconstructed and
4. substantial information about construction of TSF to be gathered which may enable
other attacks.
The formulation of “Deploying Test Features …” in FMT_LIM.2.1 might be a little bit
misleading since the addressed features are no longer available (e.g. by disabling or removing
the respective functionality). Nevertheless the combination of FMT_LIM.1 and FMT_LIM.2 is
introduced provide an optional approach to enforce the same policy. Note that the term
“software” in item 3 of FMT_LIM.1.1 and FMT_LIM.2.1 refers to both IC Dedicated and IC
Embedded Software.
The TOE shall meet the requirement “Management of TSF data (FMT_MTD.1)” as specified
below (Common Criteria Part 2). The iterations address different management functions and
different TSF data.

.
The pre-personalization Data includes but is not limited to the authentication reference data for
the Personalization Agent which is the symmetric cryptographic Personalization Agent Key.

FMT_MTD.1.1/INI_DIS The TSF shall restrict the ability to disable read access for users to 49
the Initialization Data 50
to the Personalization Agent 51
.
According to P.Manufact the IC Manufacturer and the MRTD Manufacturer are the default
users assumed by the TOE in the role Manufacturer during the Phase 2 “Manufacturing” but the
TOE is not requested to distinguish between these users within the role Manufacturer. The TOE
may restrict the ability to write the Initialization Data and the Prepersonalization Data by
(i) allowing to write these data only once and
(ii) blocking the role
Manufacturer at the end of the Phase 2. The IC Manufacturer may write the Initialization Data
which includes but are not limited to the IC Identifier as required by FAU_SAS.1. The
Initialization Data provides a unique identification of the IC which is used to trace the IC in the
Phase 2 and 3 “personalization” but is not needed and may be misused in the Phase 4
“Operational Use”. Therefore the external read access shall be blocked. The MRTD
Manufacturer will write the Pre-personalization Data.

The following security functional requirements address the protection against forced illicit
information leakage including physical manipulation.
The TOE shall meet the requirement “Failure with preservation of secure state (FPT_FLS.1)” as
specified below (Common Criteria Part 2).
FPT_FLS.1 Failure with preservation of secure state
Hierarchical to: No other components.
Dependencies: No Dependencies.
FPT_FLS.1.1 The TSF shall preserve a secure state when the following types of failures occur:
1. Exposure to out-of-range operating conditions where therefore a malfunction could
occur,
2. failure detected by TSF according to FPT_TST.1 62
.
The TOE shall meet the requirement “TSF testing (FPT_TST.1)” as specified below (Common
Criteria Part 2).
FPT_TST.1 TSF testing
Hierarchical to: No other components.
Dependencies: No Dependencies.
FPT_TST.1.1 The TSF shall run a suite of self tests [at the conditions [during initial startup,
when any command is received, during cryptographic operations]] to demonstrate the
correct operation of the TSF63
.
FPT_TST.1.2 The TSF shall provide authorised users with the capability to verify the
integrity of TSF data64
.
FPT_TST.1.3 The TSF shall provide authorised users with the capability to verify the integrity
of stored TSF executable code.
The TOE shall meet the requirement “Resistance to physical attack (FPT_PHP.3)” as specified
below (Common Criteria Part 2).
FPT_PHP.3 Resistance to physical attack
Hierarchical to: No other components.
Dependencies: No dependencies.
FPT_PHP.3.1 The TSF shall resist physical manipulation and physical probing 65
to the
TSF 66
by responding automatically such that the SFRs are always enforced.
The TOE will implement appropriate measures to continuously counter physical manipulation
and physical probing. Due to the nature of these attacks (especially manipulation) the TOE can
by no means detect attacks on all of its elements. Therefore, permanent protection against these
attacks is required ensuring that the TSP could not be violated at any time. Hence, “automatic
response” means here (i) assuming that there might be an attack at any time and (ii)
countermeasures are provided at any time.

Table 5- Coverage of Security Objective for the TOE by SFR
The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD”
addresses the access control of the writing the logical MRTD. The write access to the logical
MRTD data are defined by the SFR FDP_ACC.1 and FDP_ACF.1 as follows: only the
successfully authenticated Personalization Agent is allowed to write the data of the groups
EF.DG1 to EF.DG16 of the logical MRTD only once.
The authentication of the terminal as Personalization Agent shall be performed by TSF
according to SRF FIA_UAU.4 and FIA_UAU.5. The Personalization Agent can be
authenticated by using the symmetric authentication mechanism (FCS_COP.1/ AUTH).
FIA_AFL.1/INI and FIA_AFL.1/PER describe the authentication failures and the actions taken
after unsuccessfull authentication attempts during initialization and personalization.
In case of using the BAC mechanism the SFR FIA_UAU.6 describes the re-authentication and
FDP_UCT.1 and FDP_UIT.1 the protection of the transmitted data by means of secure
messaging implemented by the cryptographic functions according to FCS_CKM.1,
FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC as well as
FCS_COP.1/MAC for the ENC_MAC_Mode.
The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR
FMT_SMF.1 lists the TSF management functions (including Personalization) setting the
Document Basic Access Keys according to the SFR FMT_MTD.1/KEY_WRITE as
authentication reference data. The SFR FMT_MTD.1/KEY_READ prevents read access to the
secret key of the Personalization Agent Keys and ensure together with the SFR FCS_CKM.4,
FPT_EMSEC.1, FPT_FLS.1 and FPT_PHP.3 the confidentially of these keys.
The security objective OT.Data_Int “Integrity of personal data” requires the TOE to protect
the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation
and unauthorized writing. The write access to the logical MRTD data is defined by the SFR
FDP_ACC.1 and FDP_ACF.1 in the same way: only the Personalization Agent is allowed to
write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD (FDP_ACF.1.2, rule 1)

and terminals are not allowed to modify any of the data groups EF.DG1 to EF.DG16 of the
logical MRTD (cf. FDP_ACF.1.4). The SFR FMT_SMR.1 lists the roles (including
Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions
(including Personalization). The authentication of the terminal as Personalization Agent shall be
performed by TSF according to SRF FIA_UAU.4, FIA_UAU.5 and FIA_UAU.6 using either
FCS_COP.1/ENC and FCS_COP.1/MAC or FCS_COP.1/AUTH.
The security objective OT.Data_Int “Integrity of personal data” requires the TOE to ensure
that the inspection system is able to detect any modification of the transmitted logical MRTD
data by means of the BAC mechanism. The SFR FIA_UAU.6, FDP_UCT.1 and FDP_UIT.1
requires the protection of the transmitted data by means of secure messaging implemented by
the cryptographic functions according to FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for
key generation), and FCS_COP.1/ENC and FCS_COP.1/MAC for the ENC_MAC_Mode. The
SFR FMT_MTD.1/KEY_WRITE requires the Personalization Agent to establish the Document
Basic Access Keys in a way that they cannot be read by anyone in accordance to
FMT_MTD.1/KEY_READ. FCS_COP.1/SIGN requires the protection of the integrity of the
logical MRTD data by active authentication mechanism.
The security objective OT.Data_Conf “Confidentiality of personal data” requires the TOE to
ensure the confidentiality of the logical MRTD data groups EF.DG1 to EF.DG16. The SFR
FIA_UID.1 and FIA_UAU.1 allow only those actions before identification respective
authentication which do not violate OT.Data_Conf. In case of failed authentication attempts
FIA_AFL.1 enforces additional waiting time prolonging the necessary amount of time for
facilitating a brute force attack. The read access to the logical MRTD data is defined by the
FDP_ACC.1 and FDP_ACF.1.2: the successful authenticated Personalization Agent is allowed
to read the data of the logical MRTD (EF.DG1 to EF.DG16). The successful authenticated
Basic Inspection System is allowed to read the data of the logical MRTD (EF.DG1, EF.DG2
and EF.DG5 to EF.DG16). The SFR FMT_SMR.1 lists the roles (including Personalization
Agent and Basic Inspection System) and the SFR FMT_SMF.1 lists the TSF management
functions (including Personalization for the key management for the Document Basic Access
Keys). FCS_COP.1/SIGN requires the protection of confidentiality of the logical MRTD data
by active authentication mechanism. FIA_AFL.1/EXC, FIA_AFL.1/BAC, FIA_AFL.1/INI and
FIA_AFL.1/PER prevent unauthenticated users to access logical MRTD data.
The SFR FIA_UAU.4 prevents reuse of authentication data to strengthen the authentication of
the user. The SFR FIA_UAU.5 enforces the TOE to accept the authentication attempt as Basic
Inspection System only by means of the Basic Access Control Authentication Mechanism with
the Document Basic Access Keys. Moreover, the SFR FIA_UAU.6 requests secure messaging
after successful authentication of the terminal with Basic Access Control Authentication
Mechanism which includes the protection of the transmitted data in ENC_MAC_Mode by
means of the cryptographic functions according to FCS_COP.1/ENC and FCS_COP.1/MAC
(cf. The SFR FDP_UCT.1 and FDP_UIT.1). (for key generation), and FCS_COP.1/ENC and
FCS_COP.1/ MAC for the ENC_MAC_Mode. The SFR FCS_CKM.1, FCS_CKM.4,
FCS_COP.1/SHA and FCS_RND.1 establish the key management for the secure messaging
keys. The SFR FMT_MTD.1/KEY_WRITE addresses the key management and
FMT_MTD.1/KEY_READ prevents reading of the Document Basic Access Keys.
Note, neither the security objective OT.Data_Conf nor the SFR FIA_UAU.5 requires the
Personalization Agent to use the Basic Access Control Authentication Mechanism or secure
messaging.

The security objective OT.Identification “Identification and Authentication of the TOE”
address the storage of the IC Identification Data uniquely identifying the MRTD’s chip in its
non-volatile memory. This will be ensured by TSF according to SFR FAU_SAS.1.
Furthermore, the TOE shall identify itself only to a successful authenticated Basic Inspection
System in Phase 4 “Operational Use”. The SFR FMT_MTD.1/INI_ENA allows only the
Manufacturer to write Initialization Data and Pre-personalization Data (including the
Personalization Agent key). The SFR FMT_MTD.1/INI_DIS allows the Personalization Agent
to disable Initialization Data if their usage in the phase 4 “Operational Use” violates the
security objective OT.Identification. The SFR FIA_UID.1 and FIA_UAU.1 do not allow
reading of any data uniquely identifying the MRTD’s chip before successful authentication of
the Basic Inspection Terminal and will stop communication after unsuccessful authentication
attempt. In case of failed authentication attempts related to BAC authentication protocol,
FIA_AFL.1/BAC enforces additional waiting time prolonging the necessary amount of time for
facilitating a brute force attack.
The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is
ensured by the SFR FMT_LIM.1 and FMT_LIM.2 which prevent misuse of test functionality of
the TOE or other features which may not be used after TOE Delivery.
The security objective OT.Prot_Inf_Leak “Protection against Information Leakage” requires
the TOE to protect confidential TSF data stored and/or processed in the MRTD’s chip against
disclosure
- by measurement and analysis of the shape and amplitude of signals or the time between events
found by measuring signals on the electromagnetic field, power consumption, clock, or I/O
lines, which is addressed by the SFR FPT_EMSEC.1,
- by forcing a malfunction of the TOE, which is addressed by the SFR FPT_FLS.1 and
FPT_TST.1, and/or
- by a physical manipulation of the TOE, which is addressed by the SFR FPT_PHP.3.
The security objective OT.Prot_Phys-Tamper “Protection against Physical Tampering” is
covered by the SFR FPT_PHP.3.
The security objective OT.Prot_Malfunction “Protection against Malfunctions” is covered by
(i) the SFR FPT_TST.1 which requires self tests to demonstrate the correct operation and
tests of authorized users to verify the integrity of TSF data and TSF code, and
(ii) the SFR FPT_FLS.1 which requires a secure state in case of detected failure or
operating conditions possibly causing a malfunction.
6.3.2 Dependency Rationale
The dependency analysis for the security functional requirements shows that the basis for
mutual support and internal consistency between all defined functional requirements is
satisfied. All dependencies between the chosen functional components are analyzed, and non-
dissolved dependencies are appropriately explained.
The table 4 shows the dependencies between the SFR of the TOE.

Table 6 – Dependencies between the SFR for the TOE
Justification for non-satisfied dependencies between the SFR for TOE:
No. 1: The hash algorithm required by the SFR FCS_COP.1/SHA does not need any key
material. Therefore neither a key generation (FCS_CKM.1) nor an import (FDP_ITC.1/2) is
necessary.
No. 2: The SFR FCS_COP.1/AUTH uses the symmetric Personalization Key permanently
stored during the Pre-Personalization process (cf. FMT_MTD.1/INI_ENA) by the
manufacturer. Thus there is neither the necessity to generate or import a key during the
addressed TOE lifecycle by the means of FCS_CKM.1 or FDP_ITC. Since the key is
permanently stored within the TOE there is no need for FCS_CKM.4, too.
No. 3: The access control TSF according to FDP_ACF.1 uses security attributes which are
defined during the personalization and are fixed over the whole life time of the TOE. No
management of these security attribute (i.e. SFR FMT_MSA.1 and FMT_MSA.3) is necessary
here.
No. 4: The SFR FDP_UCT.1 and FDP_UIT.1 require the use secure messaging between the

MRTD and the BIS. There is no need for SFR FTP_ITC.1, e.g. to require this communication
channel to be logically distinct from other communication channels since there is only one
channel. Since the TOE does not provide a direct human interface a trusted path as required by
FTP_TRP.1 is not applicable here.
6.3.3 Security Assurance Requirements Rationale
The EAL4 was chosen to permit a developer to gain maximum assurance from positive security
engineering based on good commercial development practices which, though rigorous, do not
require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at
which it is likely to be economically feasible to retrofit to an existing product line. EAL4 is
applicable in those circumstances where developers or users require a moderate to high level of
independently assured security in conventional commodity TOEs and are prepared to incur
sensitive security specific engineering costs.
The selection of the component ALC_DVS.2 provides a higher assurance of the security of the
MRTD’s development and manufacturing especially for the secure handling of the MRTD’s
material.
The component ALC_DVS.2 augmented to EAL4 has no dependencies to other security
Requirements
Dependencies ALC_DVS.2: no dependencies.
6.3.4 Security Requirements – Mutual Support and Internal Consistency
The following part of the security requirements rationale shows that the set of security
requirements for the TOE consisting of the security functional requirements (SFRs) and the
security assurance requirements (SARs) together form a mutually supportive and internally
consistent whole.
The analysis of the TOE´s security requirements with regard to their mutual support and
internal consistency demonstrates:
The dependency analysis in Dependency Rationale for the security functional requirements
shows that the basis for mutual support and internal consistency between all defined functional
requirements is satisfied. All dependencies between the chosen functional components are
analyzed, and non-satisfied dependencies are appropriately explained.
The assurance class EAL4 is an established set of mutually supportive and internally consistent
assurance requirements. The dependency analysis for the sensitive assurance components in
section Security Assurance Requirements Rationale shows that the assurance requirements
are mutually supportive and internally consistent as all (sensitive) dependencies are satisfied
and no inconsistency appears.
Inconsistency between functional and assurance requirements could only arise if there are
functional-assurance dependencies which are not met, a possibility which has been shown not
to arise in Dependency Rationale and Security Assurance Requirements Rationale.
Furthermore, as also discussed in Security Assurance Requirements Rationale, the chosen
assurance components are adequate for the functionality of the TOE. So the assurance
