1.4. TOE Definition
10 The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine readable
travel documents (MRTD’s chip) programmed according to the Logical Data Structure (LDS)
and providing the Basic Access Control according to [ICAO-9303]
In addition to [BACPassPP], the TOE supports the active authentication as defined in [ICAO-9303].
The TOE comprises at least
§ the circuitry of the travel document’s chips(the integrated circuit, IC)
§ the IC Dedicated Software and the IC Dedicated Support Software
§ the IC Embedded Software(operating system),
§ the epassport application compliant with [ICAO-9303]
§ the associated guidance documentation
1.4.1. TOE usage and security features for operational
11 A State or Organization issues travel documents to be used by the holder for international
travel. The traveller presents a travel document to the inspection system to prove his or her
identity. The travel document in context of this security target 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 travel document’s chip according to LDS in case of
contactless machine reading. The authentication of the traveller is based on (i) the possession
of a valid travel document personalised for a holder with the claimed identity as given on the
biographical data page and (ii) biometrics using the reference data stored in the travel
document. The issuing State or Organisation ensures the authenticity of the data of genuine
travel documents. The receiving State trusts a genuine travel document of an issuing State or
Organisation.
For this security target the travel document is viewed as unit of
12 (i) the physical part of the travel document in form of paper and/or plastic and chip. It
presents visual readable data including (but not limited to) personal data of the travel
document holder
(a) the biographical data on the biographical data page of the travel document surface,
(b) the printed data in the Machine Readable Zone (MRZ) and
(c) the printed portrait.
13 (ii) the logical travel document as data of the travel document holder stored according to the
Logical Data Structure as defined in [ICAO-9303] as specified by ICAO on the contactless
integrated circuit. It presents contactless readable data including (but not limited to) personal

data of the travel document holder
(a) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1),
(b) the digitized portraits (EF.DG2),
(c) the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both
(d) the other data according to LDS (EF.DG5 to EF.DG16) and
(e) the Document Security Object (SOD).
14 The issuing State or Organisation implements security features of the travel document to
maintain the authenticity and integrity of the travel document and their data. The physical part
of the travel document and the travel document’s chip are identified by the Document
Number.
15 The physical part of the travel document is protected by physical security measures (e.g.
watermark, security printing), logical (e.g. authentication keys of the travel document’s chip)
and organisational security measures (e.g. control of materials, personalisation procedures)
[ICAO-9303]. These security measures can include the binding of the travel document’s chip
to the passport book.
16 The logical travel document is protected in authenticity and integrity by a digital signature
created by the document signer acting for the issuing State or Organisation and the security
features of the travel document’s chip.
17 The ICAO defines the baseline security methods Passive Authentication and the optional
advanced security methods Basic Access Control and Password Authenticated Connection
Establishment to the logical travel document, Active Authentication of the travel document’s
chip, Extended Access Control to and the Data Encryption of sensitive biometrics as optional
security measure in [ICAO-9303]. The Passive Authentication Mechanism and Data Encryption
are performed completely and independently of the TOE by the TOE environment.
18 This security target addresses the protection of the logical travel document (i) in integrity by
write-only-once access control and by physical means, and (ii) in confidentiality by the Basic
Access Control Mechanism. This security target addresses the Active Authentication but does
not address the Extended Access Control.
19 The Basic Access Control is a security feature which is mandatory supported by the TOE.
The inspection system (i) reads optically the travel document, (ii) authenticates itself as
inspection system by means of Document Basic Access Keys. After successful authentication
of the inspection system the travel document’ chip provides read access to the logical travel
document by means of private communication (Secure Messaging) with this inspection system
[ICAO-9303].

1.4.2. TOE Life Cycle
20 The TOE life cycle is described in terms of the four life cycle phases. (With respect to the
[PP-IC-0084], the TOE life-cycle the life-cycle is additionally subdivided into 7 steps.)
21 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(COS), the ePassport 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 is securely
delivered to the IC manufacturer. The IC Embedded Software in the non-volatile
programmable memories, the ePassport application and the guidance documentation is
securely delivered to the travel document manufacturer.
22 Phase 2 “Manufacturing”
(Step3) The TOE integrated circuit is produced by the IC manufacturer conforming with
KOMSCO requirements. The IC manufacturer writes the IC Identification Data onto
the chip to control the IC during the IC as travel document 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.
If necessary, the IC manufacturer adds the parts of the IC embedded Software in the
non-volatile programmable memories (FLASH)
(Step4) The MRTD manufacturer combines the IC with hardware for the contactless interface
in the passport book.
(Step5) The MRTD manufacturer (i) Initializes the MRTD application and (ii) equips MRTD’s
chips with pre-personalization Data.
The pre-personalized MRTD together with the IC Identifier are 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.

23 Phase 3 “Personalization of the travel document”
(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 part of the MRTD,
(iv) the writing of the TOE User Data and TSF Data into the logical MRTD and
(v) configuration of the TSF if necessary.
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.
24 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.
25 Application note 1 : In this ST, the role of the Personalization Agents is strictly limited to
the phase 3 Personalization. In the phase 4 Operational Use updating and addition of the data
groups of the MRTD application is forbidden.

Logical area in Figure 1-1 shows an overview of the TOE architecture.
• Crypto Operation : provides the cryptographic services(Triple-DES, AES, SHA, MAC, RSA,
ECC etc.)
• Authentication : loading of keys related to authentication and the function of authentication
such as PAC, BAC, AA
• Card Management : sending and receiving of APDU, integrity checking, clearing of residual
information and the function for preservation of TOE secure state
• Memory Management : creating, selection, deleting of files and management of transaction
• Secure Messaging : securemessaging for secure communication channel
• User Data : All data(being not authentication data) stored in the context of the ePassport
application of travel document as defined in [EAC-TR] and [ICAO-9303] such
as EF.DG1, EF.DG2, EF.DG5 ~ EF.DG16
• TSF Data : Data created by and for the TOE that might affect the operation of the TOE
including the private authentication key such as PAC private key, BAC key
and AA private key
Security Mechanism
29 The TOE provides security features such as confidentiality, integrity, access control and
authentication for e-Passport personalization data and TSF data security. These security features
implemented as BAC security mechanism which defined [ICAO-9303] and PAC security
mechanism for personalization. Also, The TOE consists of PA authentication for detect
e-Passport personalization data forgery through digital signature verification of SOD which is
from TOE to verification system and AA authentication features.
< PAC(Personalization Access Control) >
30 The TOE provides the PAC security mechanism which consists of PAC mutual authentication
and PAC session key generation used for access control of Personalization Agent in
initialization phase and personalization phase.
The PAC authentication is entity authentication protocol based on TDES/AES to authenticate
between Personalization Agent and TOE in personalization phase. The PAC authentication uses
TDES/AES algorithm.
The PAC session key generation feature is to make PAC session key(i.e. PAC session crypto
key and PAC session MAC key) in order to create secure channel between TOE and
Personalization Agent. The PAC session key generation is implemented by key derivation
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 11 -
protocol based on TDES/AES. The way to create secure channel is similar to that of the
BAC mechanism.
< BAC(Basic Access Control) >
31 Basic Access Control provides mutual authentication and session key establishment by means
of a three-step challenge-response protocol, Key Establishment Mechanism using Triple DES
[FIPS PUB 46-3] as block cipher. A cryptographic checksum according to [ISO_9797-1],
MAC Algorithm 3, is calculated over and appended to the ciphertexts. The modes of operation
described in [ICAO-9303] are used. Exchanged nonces must be 8 bytes long, exchanged
keying material must be 16 bytes long.
< PA(Passive Authentication) >
32 The integrity of data stored under the LDS is checked by means of the Passive Authentication
mechanism defined in [ICAO-9303]. Passive Authentication consists of the following steps :
1. The inspection system reads the Document Security Object (SOD), which contains the
Document Signer Certificate from the IC.
2. The inspection system builds and validates a certification path from a Trust Anchor to the
Document Signer Certificate used to sign the Document Security Object (SOD).
3. The inspection system uses the verified Document Signer Public Key to verify the signature
of the Document Security Object (SOD).
4. The inspection system reads relevant data groups from the IC.
5. The inspection system ensures that the contents of the data groups are authentic and
unchanged by hashing the contents and comparing the result with the corresponding hash
value in the Document Security Object (SOD).
< AA(Active Authentication) >
33 Active Authentication authenticates the IC by signing a challenge sent by the inspection
system with a private key known only to the IC[ICAO-9303].
For this purpose, the IC contains its own Active Authentication key pair. A hash representation
of Data Group 15 (public key info) is stored in the Document Security Object (SOD), and is
therefore authenticated by the issuer’s digital signature. The corresponding private key is stored
in the IC secure memory.
By authenticating the Document Security Object (SOD) and Data Group 15 by means of Passive
Authentication in combination with Active Authentication, the inspection system verifies that the
- Public - Security Target

- 12 -
Document Security Object (SOD) has been read from a genuine IC.
Additional Security Features
34 The TOE provides crypto operation, identification, authentication and access control through
the PAC and BAC secure mechanism.
The TOE manages the function such as Initialization, Pre-personalisation, Personalisation and
managing TSF data such as crypto key for security mechanism and certifications. Also, The
TOE manages the security role such as Manufacturer, Personalisation Agent, Terminal.
The TOE performs self test and provides integrity check way to ensure secure operation. While
in operation, The TOE operates countermeasure from DPA/SPA technique which is extracting
crypto information by analysing the physical phenomenon(such as current, voltage,
electro-magnetic). Also, it provides protection countermeasure from physical invasion.
IC Chip Providing Features
35 IC chip is composed of a processing unit, security components, contactless and contact based
I/O ports. IC chip also includes any IC Designer/Manufacturer proprietary IC Dedicated Software

3. Security Problem Definition
3.1. Introduction
3.1.1. Assets
44 The assets to be protected by the TOE include the User Data on the MRTD’ chip.
Logical MRTD Data
45 The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16(with dierent security
needs) and the Document Security Object EF.SOD according to LDS [ICAO-9303]. 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 and the Active Authentication Public Key (EF.DG15) for Active
Authentication. The EF.SOD is used by the inspection system for Passive Authentication of
the logical MRTD.
Due to interoperability reasons the ’ICAODoc 9303’[ICAO_9303] specifies only the BAC
mechanisms with resistance against enhanced basic attack potential granting access to
• LogicalMRTD standardUser Data (i.e. Personal Data) of theMRTD 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
46 A sensitive asset is the following more general one.
Authenticity of the MRTD’ chip
47 The authenticity of the MRTD’ chip personalized by the issuing State or Organization for the
MRTD holder is used by the traveler to prove this possession of a genuine MRTD.
3.1.2. Subjects
48 This protection profile considers the following subjects:
Manufacturer
49 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
50 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 (iv) signing the
Document Security Object defined in [ICAO-9303].
Terminal
51 A terminal is any technical system communicating with the TOE through the contactless
interface.
Inspection system (IS)
52 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. The General Inspection System (GIS) is a Basic Inspection System which
implements additionally the Chip Authentication Mechanism. The Extended Inspection System
(EIS) in addition to the General Inspection System (i) implements the Terminal Authentication
Protocol and (ii) is authorized by the issuing State or Organization through the Document
Verifier of the receiving State to read the sensitive biometric reference data. The security
attributes of the EIS are defined of the Inspection System Certificates.

- 18 -
Traveler
54 Person presenting the MRTD to the inspection system and claiming the identity of the MRTD
holder.
Attacker
55 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.
Application note 3 : 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.
3.1.3. Assumptions
56 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
57 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
58 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
59 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
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 19 -
(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
60 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
[ICAO-9303]. 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
61 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’ [ICAO-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.
62 Application note 4 : When assessing the MRZ data resp. the BAC keys entropy potential
dependencies between these data (especially single items of the MRZ) have to be considered
and taken into account. E.g. there might be a direct dependency between the Document
Number when chosen consecutively and the issuing date.
3.2. Threats
63 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.
- Public - Security Target

- 20 -
T.Chip_ID Identification of MRTD’s chip
64 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
65 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
66 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
67 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
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 21 -
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
68 The TOE shall avert the threats as specified below.
T.Abuse-Func Abuse of Functionality
69 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
70 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
71 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
72 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 (ii) circumvent,
deactivate or modify security functions of the MRTD’s chip Embedded
Software.
This may be achieved e.g. by operating the MRTD’s chip outside the normal
operating conditions, exploiting errors in the MRTD’s chip Embedded
Software or misusing administration function. To exploit these vulnerabilities

an attacker needs information about the functional operation.
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
3.3. Organizational Security Policies
73 The TOE shall comply with the following Organizational Security Policies (OSP) as security
rules, procedures, practices, or guidelines imposed by an organization upon its operations (see
CC part 1, sec. 3.2).
P.Manufact Manufacturing of the MRTD’s chip
74 The Initialization Data are written by the IC Manufacturer to identify the IC uniquely. The
MRTD Manufacturer writes the Pre-personalization Data which contains at least the
Personalization Agent Key.
P.Personalization Personalization of the MRTD by issuing State or Organization only
75 The issuing State or Organization guarantees the correctness of the biographical data, the
printed portrait and the digitized portrait, the biometric reference data and other data of the
logical MRTD with respect to the MRTD holder. The personalization of the MRTD for the
holder is performed by an agent authorized by the issuing State or Organization only.
P.Personal_Data Personal data protection policy
76 The biographical data and their summary printed in the MRZ and stored on the MRTD’s chip
(EF.DG1), the printed portrait and the digitized portrait (EF.DG2), the biometric reference data
of finger(s) (EF.DG3), the biometric reference data of iris image(s) (EF.DG4)3 and data
according to LDS (EF.DG5 to EF.DG13, EF.DG16) stored on the MRTD’s chip are personal
data of the MRTD holder. These data groups are intended to be used only with agreement of
the MRTD holder by inspection systems to which the MRTD is presented. The MRTD’s chip
shall provide the possibility for the Basic Access Control to allow read access to these data
only for terminals successfully authenticated based on knowledge of the Document Basic
Access Keys as defined in [ICAO-9303].
P.Activ_Auth Active Authentication
77 The TOE implements the active authentication protocol as described in [ICAO-9303].

4. Security Objectives
78 This chapter 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
79 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.
80 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 [ICAO-9303] 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.DG 3 to EF.DG16 are added.
81 Application note 5 : The OT.AC_Pers implies that
(1) the data of the LDS groups written during personalization for MRTD holder (at least
EF.DG1 and EF.DG2) can not be changed by write access after personalization,
(2) the Personalization Agents may (i) add (fill) data into the LDS data groups not written
yet, and (ii) update and sign the Document Security Object accordingly. The support for
adding data in the “Operational Use” phase is optional.
82 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.
83 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
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 25 -
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.
84 Application note 6 : 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’ [ICAO-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 security
target. Thus the read access must be prevented even in case of a successful BAC
Authentication.
85 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.
86 Application note 7 : 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
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 26 -
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.
87 OT.Active_Auth_Proof Proof of MRTD’s chip authenticity by AA
The TOE must support the Basic Inspection Systems to verify the identity and authenticity of
the MRTD’s chip as issued by the identified issuing State or Organization by means of the
Active Authentication as defined in [ICAO-9303]. The authenticity proof through AA provided
by MRTD’s chip shall be protected against attacks with high attack potential.
88 The following TOE security objectives address the protection provided by the MRTD’s chip
independent of the TOE environment.
89 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.
90 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.
91 Application note 8 : This security objective pertains to measurements with subsequent complex
signal processing due to normal operation of the TOE or operations enforced by an attacker.
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 27 -
Details correspond to an analysis of attack scenarios which is not given here.
92 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.
93 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.
94 Application note 9 : A malfunction of the TOE may also be caused using a direct
interactionwith 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

Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 29 -
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 according to
[ICAO-9303].
100 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’ [ICAO-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.
Receving State or Organization
101 The receiving State or Organization will implement the following security objectives of the
environment.
102 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 [ICAO-9303].
103 OE.Passive_Auth_Verif Verification by Passive Authentication
The border control officer of the receiving State uses the inspection system to verify the
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 30 -
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

107 The OSP P.Manufact “Manufacturing of the MRTD’s chip” requires a unique identification of
the IC by means of the Initialization Data and the writing of the Pre-personalization Data as
being fulfilled by OT.Identification.
108 The OSP P.Personalization “Personalization of the MRTD by issuing State or Organization
only” addresses the (i) the enrolment of the logical MRTD by the Personalization Agent as
described in the security objective for the TOE environment OE.Personalization
“Personalization of logical MRTD”, and (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)
- Public - Security Target

- 32 -
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.
109 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 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.
110 In addition, the OSP P.Active_Auth is countered by chip an identification and authenticity
proof required by OT.Active_Auth_Proof “Proof of travel document’s chip authenticity by AA”
using an authentication key pair to be generated by the issuing State or Organization. The
Public Active Authentication Key has to be written into EF.DG15 and signed by means of
Documents Security Objects as demanded by OE.Active_Auth_Key_Travel_Document “the
travel document Authentication Key”.
111 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.
112 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.
113 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
- Public - Security Target

- 33 -
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”.
114 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.
115 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 against
Malfunctions”.
116 The assumption A.MRTD_Manufact “MRTD manufacturing on step 4 to 6” is covered by the
security objective for the TOE environment OE.MRTD_Manufact “Protection of the MRTD
Manufacturing” that requires to use security procedures during all manufacturing steps.
The assumption A.MRTD_Delivery “MRTD delivery during step 4 to 6” is covered by the
security objective for the TOE environment OE.MRTD_Delivery “Protection of the MRTD
delivery” that requires to use security procedures during delivery steps of the MRTD.

117 The assumption A.Pers_Agent “Personalization of the MRTD’s chip” is covered by the
security objective for the TOE environment OE.Personalization “Personalization of logical
MRTD” including the enrolment, the protection with digital signature and the storage of the
MRTD holder personal data.
118 The examination of the MRTD passport book addressed by the assumption A.Insp_Sys
“Inspection Systems for global interoperability” is covered by the security objectives for the
TOE environment OE.Exam_MRTD “Examination of the MRTD passport book”. The security
objectives for the TOE environment OE.Prot_Logical_MRTD “Protection of data from the
logical MRTD” will require the Basic Inspection System to implement the Basic Access
Control and to protect the logical MRTD data during the transmission and the internal
handling.
119 The assumption A.BAC-Keys “Cryptographic quality of Basic Access Control Keys” is
directlycovered by the security objective for the TOE environment OE.BAC-Keys
“Cryptographic quality of Basic Access Control Keys” ensuring the sufficient key quality to be
provided by the issuing State or Organization.

5. Extended Components Definition
120 This ST uses components defined as extensions to CC part 2. Some of these components are
defined in protection profile [PP-IC-0084]; others are defined in the protection profile
[BACPassPP].
5.1. Definition of the family FAU_SAS
121 To describe the security functional requirements of the TOE, the 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 behaviour: This family defines functional requirements for the storage of audit data.
Component leveling: FAU_SAS Audit data storage 1
FAU_SAS.1 Requires the TOE to provide the possibility to store audit data
Management There are no management activities foreseen.
Audit 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
122 To describe the IT security functional requirements of the TOE, the 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.1 is not limited to generation of cryptographic keys unlike the
component FCS_CKM.1. The similar component FIA_SOS.2 is intended for
noncryptographic use.
The family ‘Generation of random numbers (FCS_RND)’ is specified as follows:
5.3. Definition of the family FMT_LIM
123 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
FCS_RND Generation of random numbers
Family behaviour:
This family defines quality requirements for the generation of random
numbers which are intended to be used for cryptographic purposes.
Component leveling: FCS_RND Generation of random numbers 1
FCS_RND.1
Generation of random numbers requires that random numbers meet a defined
quality metric.
Management There are no management activities foreseen.
Audit There are no actions defined to be auditable
FCS_RND.1 Quality metric for random numbers
Hierarchical to: No other components

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
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.1 Limited capabilities
FMT_LIM Limited capabilities and availability
Family behaviour:
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:
1
FIA_API Authentication Proof of Identitiy
2
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.
Management There are no management activities foreseen.
Audit There are no actions defined to be auditable
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
life-cycle.
Management There are no management activities foreseen.
Audit There are no actions defined to be auditable

124 Application Note 10 : The functional requirements FMT_LIM.1 and FMT_LIM.2 assume
existence of two types of mechanisms (limited capabilities and limited availability) which
together shall provide protection in order to enforce the related 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 high functionality, but is removed or disabled in the product
in its user environment.
The combination of both the requirements shall enforce the related policy
5.4. Definition of the family FPT_EMSEC
125 The 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 secret data stored in and used by the TOE 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 being not directly addressed by any other component of
CC part 2 [CC].
Hierarchical to: No other components
Dependencies: FMT_LIM.2 Limited availability.
FMT_LIM.1.1

6. Security Requirements
126 The CC allows several operations to be performed on functional requirements; refinement,
selection, assignment, and iteration are defined in section 8.1 of Part 1 of the Common
Criteria [CC]. Each of these operations is used in this ST.
127 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.
128 The selection operation is used to select one or more options provided by the CC in stating a
requirement. Selections that have been made by the PP author are denoted as underlined text.
and the original text of the compnent is given by a footnot. Selections to be filled in by the
ST author appear in square brackets with an indication that a selection is to be made,
[selection:], and underlined text with “<” like .
129 The assignment operation is used to assign a specific value to an unspecified parameter, such
as the length of a password. Assignments that have been made by the PP authors are denoted
by showing as underlined text and the original text of the component is given by a footnote.
Assignments to be filled in by the ST author appear in square brackets with an indication that
an assignment is to be made [assignment:], and are italicized. In some cases the assignment
made by the PP authors defines a selection to be performed by the ST author. Thus this text
is underlined and italicized with “<” like .
130 The iteration operation is used when a component is repeated with varying operations.
Iteration is denoted by showing a slash “/”, and the iteration indicator after the component
identifier.
131 The definition of the subjects “Manufacturer”, “Personalization Agent”, “Basic Inspection
System” and “Terminal” used in the following chapter is given in section 3.1. Note, that all
these subjects are acting for homonymous external entities. All used objects are defined in
section 8. The operations “write”, “read”, “modify”, and “disable read access” are used in
accordance with the general linguistic usage. The operations “transmit”, “receive” and
“authenticate” are originally taken from [CC].

162 Application Note 20 : 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 creates 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. Aer 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.
163 Application Note 21 : 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’ chip use a randomly chosen identifier for the communication channel to allow the
terminal to communicate with more then one RFID. This identifier will not violate the

169 Application Note 23 : The authentication mechanisms use a challenge freshly and randomly
generated by the TOE to prevent reuse of a response generated by a terminal in a successful
authentication attempt.
170 Application Note 24 : The Basic Access Control Mechanism is a mutual device authentication
mechanism defined in [ICAO-9303]. In the first step the terminal authenticates itself to the
MRTD’ chip and the MRTD’ chip authenticates to the terminal in the second step. In this
second step the MRTD’ chip provides the terminal with a challenge-response-pair which allows
a unique identification of the MRTD’ 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.

173 Application note 25 : In case the ‘Common Criteria Protection Profile Machine Readable
Travel Document with „ICAO Application", Extended Access Control’ [EACPassPP] should
also be fulfilled the Personalization Agent should not be authenticated by using the BAC or
the symmetric authentication mechanism as they base on the two-key Triple-DES. The
Personalization Agent could be authenticated by using the symmetric AES-based authentication
mechanism or other (e.g. the Terminal Authentication Protocol using the Personalization Key,
cf. [EACPassPP] FIA_UAU.5.2).
174 Application note 26 : The Basic Access Control Mechanism includes the secure messaging for
all commands exchanged after successful authentication of the inspection system. The
Personalization Agent may use Symmetric Authentication Mechanism without secure messaging
mechanism as well if the personalization environment prevents eavesdropping to the
communication between TOE and personalization terminal. The Basic Inspection System may
use the Basic Access Control Authentication Mechanism with the Document Basic Access

176 Hierarchical to: No other components.
Dependencies: No dependencies.
177 Application note 27 : The Basic Access Control Mechanism specified in [ICAO-9303] 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.
178 Application note 28 : Note that in case the TOE should also fulfill [EACPassPP] the BAC
communication might be followed by a Chip Authentication mechanism establishing a new
secure messaging that is distinct from the BAC based communication. In this case the
condition in FIA_UAU.6 above should not contradict to the option that commands are sent to
the TOE that are no longer meeting the BAC communication but are protected by a more
secure communication channel established after a more advanced authentication process.

sensitive contact according to ISO/IEC 7816-2 as well. Examples of measurable phenomena
include, but are not limited to variations in the power consumption, the timing of signals and
the electromagnetic radiation due to internal operations or data transmissions.

227 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. PAC key for authentication between
Personalization Agent and TOE can be updated according to SFR FMT_MTD.1/PAC_KEY.
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 either by using the BAC mechanism (FCS_CKM.1/BAC, FCS_COP.1/SHA,
FCS_RND.1 (for key generation), and FCS_COP.1/ENC as well as FCS_COP.1/MAC) with the
personalization key or for reasons of interoperability with the [EACPassPP] by using the
symmetric authentication mechanism (FCS_COP.1/AUTH).
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/BAC,
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 SFR FCS_CKM.1/PAC and FCS_COP.1/PAC allows to protect the transmitted data by
means secure messaging during the presonalization processes.
228 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). PAC key for authentication between Personalization Agent and
TOE can be updated according to SFR FMT_MTD.1/PAC_KEY. 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/BAC, 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.
The SFR FMT_MTD.1/AAPK and FMT_MTD.1/KEY_READ requires that the Active
Authentication Key cannot be written unauthorized or read afterwards.
In personalization, the SFR FCS_CKM.1/PAC and FCS_COP.1/PAC ensure the authenticity of
data transfers after successful authentication of the personalization agent.
229 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/BAC 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). 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/BAC, 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.
In personalization, the SFR FCS_CKM.1/PAC and FCS_COP.1/PAC ensure the confidentiality
of data transfers after successful authentication of the personalization agent according to
FIA_UID.1 and FIA_UAU.1 with the support of FIA_AFL.1/PAC.
230 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 (cf. Application note 24). In case of failed authentication attempts FIA_AFL.1/BAC,
enforces additional waiting time prolonging the necessary amount of time for facilitating a
brute force attack.

231 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
232 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.
233 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.
234 The security objective OT.Active_Auth_Proof “Proof of MRTD’s chip authenticity through
AA” addresses the verification of the chip's authenticity. This done by the SFR FIA_API.1/AA
which authenticates the chip, using cryptographic operations covered by the SFR
FCS_COP/AA_SIGN. The Active Authentication Protocol is performed using a TOE internally
stored confidential private key as required by FMT_MTD.1/AAPK and
FMT_MTD.1/KEY_READ.

237 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.
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.
No. 5: Since AA doesn’t provide for generation or destruction of cryptographic keys, the

6.3.3. Security Assurance Requirements Rationale
238 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 has no dependencies.
Notice that it the augmentation components ADV_FSP.5, ADV_INT.2, ADV_TDS.4,
ALC_CMS.5, ALC_TAT.2 and ATE_DPT.3 come from the EAL5 level.
6.3.4. Secuirty Requirements – Mutual Support and Internal Consistency
239 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 section 6.3.2 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
- Public - Security Target
Copyright Ⓒ 2019 KOMSCO. All rights reserved EPS-05-AN-ST-BAC(Lite)
- 74 -
section 6.3.3 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 sections 6.3.2 Dependency Rationale and 6.3.3 Security Assurance Requirements
Rationale. Furthermore, as also discussed in section 6.3.3 Security Assurance Requirements
Rationale, the chosen assurance components are adequate for the functionality of the TOE. So
the assurance requirements and security functional requirements support each other and there

7. TOE Summary Specification
240 The following sections provide a general understanding of how the TOE is implemented. This
chapter describes the TOE Security Functions and the Assurance Measures covering the
requirements of the previous chapter.
7.1. TOE Security Functions
241 This chapter gives the overview description of the different TOE Security Functions composing
the TSF.
Security Feature Description
SF.IC IC chip security feature
SF.PAC_AUTH PAC authentication and creation of PAC session key
SF.BAC_AUTH BAC authentication and creation of BAC session key
SF.ACTIVE_AUTH AA authentication
SF.SEC_MESSAGE Secure messaging
SF.ACC_CONTROL TSF Access control
SF.RELIABILITY Protection against Physical Manipulation, TSF selftest, Integrity check
(Table 7-1) TOE Security Feature
7.1.1. SF.IC
242 The TOE uses TSFs provided by IC chip to enforce security. Refer to documents related to
IC chip for details of TSF of the IC chip [HWST].
7.1.2. SF.PAC_AUTH
243 This TSF includes the PAC authentication mechanism for Personalization Agent, the PAC
authentication mechanism provides authority control of the security role to the Personalization
Agent in the personalization phase. It is composed of PAC Initialization, PAC mutual
authentication and PAC session key generation.

• PAC Initialization
244 During the PAC Initialization, TOE generates key encryption key(KEK), initializes the file
table for LDS filesystem. By performing PAC Initialization, the initialization parameters
including PAC authentication key are securely loaded to TOE and the state transition from
Empty to Unissue has occurred. PAC Initialization can be performed only once and the state
transition from Unissue to Empty is irreversible.
• PAC mutual authentication
245 TOE and Personalization Agent authenticate mutually each other. Personalization Agent sends
the data to the TOE, then TOE authenticates the Personalization Agent by performing a MAC
verification and comparison received cryptographic value. Then TOE sends cryptographic value
to the Personalization Agent and Personalization Agent can ensure that TOE is the
authenticated one by performing a MAC verification and comparison response cryptographic
value.
• PAC session key generation
246 After successfully PAC mutual authentication, PAC session keys are generated to establish
secure communication channel between TOE and Personalization Agent. The User data and
TSF data should be personalized to TOE by means of secure messaging with PAC session
keys.
7.1.3. SF.BAC_AUTH
247 If the Inspection System does not perform SAC mechanism, it performs BAC mechanism. The
BAC security mechanism(Basic Access Control) provides confidentiality and integrity for the
personal data of the ePassport holder via secure messaging when controlling access to the
personal data of the ePassport holder records in the TOE and transmitting it to the Inspection
System with read-rights. This TSF is composed of BAC mutual authentication and BAC
session key generation.
7.1.4. SF.ACTIVE_AUTH
248 This TSF provides an AA mechanism with which the TOE verifies that the MRTD chip is
genuine to the Inspection System by signing the random number transmitted from the Inspection
System; the Inspection System verifies the authenticity of the MRTD chip through verification

with the signed values. In personalization phase AA private key is written into the TOE’s
securely protected area and public key is stored into DG15.
7.1.5. SF.SEC_MESSAGE
249 This TSF provides a secure communication channel to protect the command message(C-APDU)
and response message(R-APDU) between the TOE and the Personalization Agent or the
Inspection System. The secure communication channel means that between TOE and
Personalization Agent, that between TOE and Inspection System.
7.1.6. SF.ACC_CONTROL
250 This TSF regulates all access by external entities to operations of the TOE which are only
executed after this TSF allowed access. The TOE provides access control rules and
management functions for the ePassport application data based on security.
7.1.7. SF.RELIABILITY
251 This TSF executes the residual information management, ensures that any information content
of the related crypto is made unavailable. It also performs self-test, provides integrity check,
preserves the secure protection when case of abnormal operation and provides countermeasure
from physical invasion. etc..

8.2. Glossary
Accurate Terminal Certificate A Terminal Certificate is accurate, if the issuing Document Verifier is
trusted by the travel document’'s chip to produce Terminal Certificates with the correct certificate
effective date, see [EAC-TR].
Advanced Inspection Procedure (with PACE) A specific order of authentication steps between a travel
document and a terminal as required by [ICAO_SAC], namely (i) PACE, (ii) Chip
Authentication v.1, (iii) Passive Authentication with SOD and (iv) Terminal Authentication v.1.
AIP can generally be used by EIS-AIP-PACE and EIS-AIP-BAC.
Agreement This term is used in BSI-CC-PP-0056-V2-2011 [PACEPassPP] in order to reflect an
appropriate relationship between the parties involved, but not as a legal notion.
Active Authentication Security mechanism defined in [ICAO-9303] option by which means the travel
document’'s chip proves and the inspection system verifies the identity and authenticity of the
travel document’'s chip as part of a genuine travel document issued by a known State of
Organization.
Application note / Note Optional informative part of the ST containing sensitive supporting information
hat is considered relevant or useful for the construction, evaluation, or use of the TOE.
Audit records Write-only-once non-volatile memory area of the travel document’'s chip to store the
Initialization Data and Pre-personalization Data.
Authenticity Ability to confirm the travel document and its data elements on the travel document’'s chip
were created by the issuing State or Organization
Basic Access Control (BAC) Security mechanism defined in [ICAO-9303] by which means the travel
document’'s chip proves and the basic inspection system protects their communication by means of
secure messaging with Document Basic Access Keys (see there).
Basic Inspection System with PACE protocol (BIS-PACE) A technical system being used by an
inspecting authority and operated by a governmental organization (i.e. an Official Domestic or
Foreign Document Verifier) and verifying the travel document presenter as the travel document
holder (for ePassport: by comparing the real biometric data (face) of the travel document presenter
with the stored biometric data (DG2) of the travel document holder).

The Basic Inspection System with PACE is a PACE Terminal additionally supporting/applying the
Passive Authentication protocol and is authorized by the travel document Issuer through the
Document Verifier of receiving state to read a subset of data stored on the travel document.
Basic Inspection System (BIS) An inspection system which implements the terminals part of the Basic
Access Control Mechanism and authenticates itself to the travel document’'s chip using the
Document Basic Access Keys derived from the printed MRZ data for reading the logical travel
document.
Biographical data (biodata) The personalized details of the travel document holder appearing as text in
the visual and machine readable zones on the biographical data page of a passport book or on a
travel card or visa. [ICAO-9303]
Biometric reference data Data stored for biometric authentication of the travel document holder in the
travel document’'s chip as (i) digital portrait and (ii) optional biometric reference data.
Card Access Number (CAN) Password derived from a short number printed on the front side of the
data-page.
Certificate chain A sequence defining a hierarchy certificates. The Inspection System Certificate is the
lowest level, Document Verifier Certificate in between, and Country Verifying Certification
Authority Certificates are on the highest level. A certificate of a lower level is signed with the
private key corresponding to the public key in the certificate of the next higher level.
Counterfeit An unauthorized copy or reproduction of a genuine security document made by whatever
means. [ICAO-9303]
Country Signing CA Certificate (CCSCA) Certificate of the Country Signing Certification Authority
Public Key (KPuCSCA) issued by Country Signing Certification Authority and stored in the
inspection system.
Country Signing Certification Authority (CSCA) An organization enforcing the policy of the travel
document Issuer with respect to confirming correctness of user and TSF data stored in the travel
document. The CSCA represents the country specific root of the PKI for the travel documents and
creates the Document Signer Certificates within this PKI. The CSCA also issues the self-signed
CSCA Certificate (CCSCA) having to be distributed by strictly secure diplomatic means, see.

[ICAO-9303], 5.5.1. The Country Signing Certification Authority issuing certificates for Document
Signers (cf. [ICAO-9303]) and the domestic CVCA may be integrated into a single entity, e.g. a
Country Certification Authority. However, even in this case, separate key pairs must be used for
different roles, see [EAC-TR].
Country Verifying Certification Authority (CVCA) An organization enforcing the privacy policy of the
travel document Issuer with respect to protection of user data stored in the travel document (at a
trial of a terminal to get an access to these data). The CVCA represents the country specific root
of the PKI for the terminals using it and creates the Document Verifier Certificates within this
PKI. Updates of the public key of the CVCA are distributed in form of CVCA Link-Certificates,
see [EAC-TR].
Since the Standard Inspection Procedure does not imply any certificate-based terminal authentication,
the current TOE cannot recognize a CVCS as a subject; hence, it merely represents an
organizational entity within BSI-CC-PP-0056-V2-2012.
The Country Signing Certification Authority (CSCA) issuing certificates for Document Signers (cf.
[ICAO-9303]) and the domestic CVCA may be integrated into a single entity, e.g. a Country
Certification Authority. However, even in this case, separate key pairs must be used for different
roles, see [EAC-TR].
Current date The maximum of the effective dates of valid CVCA, DV and domestic Inspection System
certificates known to the TOE. It is used the validate card verifiable certificates.
CV Certificate Card Verifiable Certificate according to [EAC-TR].
CVCA link Certificate Certificate of the new public key of the Country Verifying Certification
Authority signed with the old public key of the Country Verifying Certification Authority where
the certificate effective date for the new key is before the certificate expiration date of the
certificate for the old key.
Document Basic Access Key Derivation Algorithm The [ICAO-9303] describes the Document Basic
Access Key Derivation Algorithm on how terminals may derive the Document Basic Access Keys
from the second line of the printed MRZ data.
PACE passwords Passwords used as input for PACE. This may either be the CAN or the SHA-1-value
of the concatenation of Serial Number, Date of Birth and Date of Expiry as read from the MRZ,
see [ICAO-9303].

Document Details Data Data printed on and electronically stored in the travel document representing the
document details like document type, issuing state, document number, date of issue, date of expiry,
issuing authority. The document details data are less-sensitive data.
Document Security Object (SOD) A RFC 3369 CMS Signed Data Structure, signed by the Document
Signer (DS). Carries the hash values of the LDS Data Groups. It is stored in the travel
document’'s chip. It may carry the Document Signer Certificate (CDS). [ICAO-9303]
Document Signer (DS) An organization enforcing the policy of the CSCA and signing the Document
Security Object stored on the travel document for passive authentication.
A Document Signer is authorized by the national CSCA issuing the Document SignerCertificate
(CDS)(CDS), see [EAC-TR] and [ICAO-9303].
This role is usually delegated to a Personalization Agent.
Document Verifier (DV) An organization enforcing the policies of the CVCA and of a Service Provider
(here: of a governmental organization / inspection authority) and managing terminals belonging
together (e.g. terminals operated by a State’'s border police), by - inter alia - issuing Terminal
Certificates. A Document Verifier is therefore a Certification Authority, authorized by at least the
national CVCA to issue certificates for national terminals, see [EAC-TR].
Since the Standard Inspection Procedure does not imply any certificate-based terminal authentication,
the current TOE cannot recognize a DV as a subject; hence, it merely represents an organizational
entity within this ST.
There can be Domestic and Foreign DV: A domestic DV is acting under the policy of the
domestic CVCA being run by the travel document Issuer; a foreign DV is acting under a policy
of the respective foreign CVCA (in this case there shall be an appropriate agreement between the
travel document Issuer and a foreign CVCA ensuring enforcing the travel document Issuer’'s
privacy policy).1,2
Eavesdropper A threat agent with high attack potential reading the communication between the travel
document’'s chip and the inspection system to gain the data on the travel document’'s chip.
Enrollment The process of collecting biometric samples from a person and the subsequent preparation
and storage of biometric reference templates representing that person’'s identity. [ICAO-9303]
Travel document (electronic) The contact based or contactless smart card integrated into the plastic or
paper, optical readable cover and providing the following application: ePassport.

or portrait. [ICAO-9303]
Global Interoperability The capability of inspection systems (either manual or automated) in different
States throughout the world to exchange data, to process data received from systems in other
States, and to utilize that data in inspection operations in their respective States. Global
interoperability is a major objective of the standardized specifications for placement of both eye
readable and machine readable data in all travel documents. [ICAO-9303]
