1.3. TOE Overview
3 The TOE is the native chip operating system(COS), MRTD application and MRTD application
data implemented on the IC chip and additionally includes S3D384E version 2, which is a
contactless IC chip of Samsung Electronics and is certified according to CC EAL
6+(ANSSI-CC-2024/02-R01).
4 According to the Technical Guideline [EAC-TR] and [ICAO 9303], the ePassport Application
supports Passive Authentication, Password Authenticated Connection Establishment (PACE),
Terminal and Chip Authentication(EAC), Active Authentication(AA) and also Basic Access
Control (BAC).
5 In this Security Target, BAC is not considered for evaluation.
6 the TOE also carries out the PAC (Personalization Access Control), which is a security
mechanism for the secure personalization and management on the personalization phase at the
Personalization Agent.
7 The main objectives of this ST are:
- To introduce TOE and the MRTD application,
- To define the scope of the TOE and its security features,
- To describe the security environment of the TOE, including the assets to be protected
and the threats to be countered by the TOE and its environment during the product
development, production and usage.
- To describe the security objectives of the TOE and its environment supporting in terms of
integrity and confidentiality of application data and programs and of protection of the TOE.
- To specify the security requirements which includes the TOE security functional
requirements, the TOE assurance requirements and TOE security functions.
8 The TOE uses generation of random numbers. TDES, AES, Retail MAC, CMAC, RSA and
ECC supported by the MRTD chip. And the TOE can use RSA or ECC operations but the
Personalization Agent has to select one cryptographic algorithm needed for EAC operation
9 Since The TOE is a composite evaluation product, it includes IC chip, COS, application
programs, and etc. There is no non-TOE HW/FW/SW requested to perform TOE security
attributes. Note, the RF antenna and the booklet are needed to represent a complete MRTD to
ePassport holder, nevertheless these parts are not inevitable for the secure operation of the
TOE.

1.4. TOE Definition
10 The Target of Evaluation (TOE) addressed by the current security target is an electronic travel
document representing a contactless smart card programmed according to Logical data structure
(LDS) and protocols specified in [ICAO-9303] and additionally providing the Extended Access
Control according to BSI TR-03110 part 1 and part 3 [EAC-TR] and Active Authentication
according to [ICAO-9303]. The communication between terminal and chip shall be protected
by Password Authenticated Connection Establishment (PACE) according to Electronic Passport
using Standard Inspection Procedure with PACE [PACEPassPP]. If Chip Authentication
Mapping(PACE-CAM) as mapping of PACE protocol is performed, Terminal Authentication
can be performed without Chip Authentication.
The TOE comprises of at least
§ the circuitry of the travel document’s chips(the integratedcircuit, 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 Organization ensures the authenticity of the data of genuine
travel documents. The receiving State trusts a genuine travel document of an issuing State or
Organization.
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
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 4 -
(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.
(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).
13 The issuing State or Organization 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. 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 organizational security measures (e.g. control of materials, personalization procedures)
[ICAO-9303]. These security measures can include the binding of the travel document’s chip
to the passport book.
14 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 Organization and the security
features of the travel document’s chip.
15 The ICAO defines the baseline security methods Passive Authentication and the optional
advanced security methods Basic Access Control 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], and Password
Authenticated Connection Establishment. The Passive Authentication Mechanism is performed
completely and independently of the TOE by the TOE environment.
16 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
Extended Access Control Mechanism. This security target addresses the Chip Authentication
Version 1 described in [EAC-TR] as an alternative to the Active Authentication stated in
[ICAO-9303].
17 BAC is also supported by the TOE, but this is not considered in the scope of this Security

Target due to the fact that BAC provides only resistance against enhanced basic attack
potential (i.e. AVA_VAN.3).
18 The confidentiality by Password Authenticated Connection Establishment (PACE) is a
mandatory security feature that shall be implemented by the TOE. The travel document shall
strictly conform to the ‘Common Criteria Protection Profile Machine Readable Travel
Document using Standard Inspection Procedure with PACE (PACE PP)’ [PACEPassPP]. Note
that this PP considers high attack potential.
19 For the PACE protocol according to [ICAO-9303], the following steps shall be performed:
(i) the travel document's chip encrypts a nonce with the shared password, derived from the
MRZ resp. CAN data and transmits the encrypted nonce together with the domain
parameters to the terminal.
(ii) The terminal recovers the nonce using the shared password, by (physically) reading the
MRZ resp. CAN data.
(iii) The travel document's chip and terminal computer perform a Diffie-Hellmann key
agreement together with the ephemeral domain parameters to create a shared secret. Both
parties derive the session keys KMAC and KENC from the shared secret.
(iv) Each party generates an authentication token, sends it to the other party and verifies the
received token.
20 After successful key negotiation the terminal and the travel document's chip provide private
communication (secure messaging) [ICAO-9303], [EAC-TR].
21 The security target requires the TOE to implement Active Authentication described in
[ICAO-9303]. This protocol provides evidence of the travel document’ chip authenticity.
22 The security target requires the TOE to implement the Chip Authentication defineded in
[EAC-TR]. The Chip Authentication prevents data traces described in [ICAO-9303]. The Chip
Authentication is provided by the following steps: (i) the inspection system communicates by
means of secure messaging established by Basic Access Control or PACE, (ii) the inspection
system reads and verifies by means of the Passive Authentication the authenticity of the
MRTD’s Chip Authentication Public Key using the Document Security Object, (III) the
inspection system generates an ephemeral key pair, (iv) the TOE and the inspection system
agree on two session keys for secure messaging in ENC_MAC mode according to the
Diffie-Hellman Primitive and (v) the inspection system verifies by protocol properly. The Chip
Authentication requires collaboration of the TOE and the TOE environment.
23 The security target requires the TOE to implement the Extended Access Control as defined in
[EAC-TR]. The Extended Access Control consists of two parts (i) the Chip Authentication
Protocol Version 1 and (ii) the Terminal Authentication Protocol Version 1 (v.1). The Chip
- Public - Security Target

- 6 -
Authentication Protocol v.1 (i) authenticates the travel document’s chip to the inspection
system and (ii) establishes secure messaging which is used by Terminal Authentication v.1 to
protect the confidentiality and integrity of the sensitive biometric reference data during their
transmission from the TOE to the inspection system. Therefore Terminal Authentication v.1
can only be performed if Chip Authentication v.1 has been successfully executed. The
Terminal Authentication Protocol v.1 consists of (i) the authentication of the inspection system
as entity authorized by the receiving State or Organization through the issuing State, and (ii)
an access control by the TOE to allow reading the sensitive biometric reference data only to
successfully authenticated authorized inspection systems. The issuing State or Organization
authorizes the receiving State by means of certification the authentication public keys of
Document Verifiers who create Inspection System Certificates.
24 Application note 1 : In addition, the TOE supports PACE Chip Authentication Mapping
(PACE-CAM) according to [ICAO-9303]. If PACE-CAM is performed, Terminal Authentication
can be performed without explicit Chip Authentication beforehand. The secure messaging
established by the PACE protocol is preserved to protect the data transmission from the TOE
to the inspection system.
1.4.2. TOE Life Cycle
25 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.)
26 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 Softswre (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.

- 7 -
Phase 2 “Manufacturing”
(Step3) The TOE integrated circuit is produced by the IC manufactureer 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 manufacture 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.
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 personalised MRTD

- 8 -
(together with appropriate guidance for TOE use if necessary) is handed over to the MRTD
holder for operational use.
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.
Application note 2 : 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.
Actors
The TOE is a composite evaluation product. For this reason, the evaluation of from (Step 1)
to (Step 3) coverd by ALC assurance. And then, the process of delivery between

Logical area in Figure 1-1 shows an overview of the TOE architecture.
• Crypto Operation : provides the cryptographic services(3-DES, AES, SHA, MAC, RSA, ECC etc.)
• Authentication : loading of keys related to authentication and the function of authentication
such as PAC, SAC, AA, EAC
• 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 Private Chip Authentication
Key and Private Active Authentication Key
Security Mechanism
27 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 SAC and EAC security mechanism which defined [ICAO-9303] and [EAC-TR]
and PAC security mechanism for personalization. Also, The TOE consists of PA authentication
and AA authentication features for detect e-Passport personalization data forgery through digital
signature verification of SOD which is from TOE to verification system.
< PAC(Personalization Access Control) >
28 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.
29 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. However, according to Application note 29 [BACPassPP], it does not
include 2-KEY based TDES algorithm for evaluation scope.
30 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

- 12 -
Personalization Agent. The PAC session key generation is implemented by key derivation
protocol based on TDES/AES. The way to create secure channel is similar to that of the
BAC mechanism.
< SAC(Supplemental Access Control) >
31 PACE is a password-authenticated Diffie-Hellman key agreement protocol that provides secure
communication and password-based authentication of the travel-document chip and the inspection
system (i.e. the travel-document chip and the inspection system share the same password).
32 PACE establishes secure messaging between an travel-document chip and an inspection system
based on possibly weak (short) passwords. The security context is established in the
EF.CardAccess. The protocol enables the travel-document chip to verify that the inspection
system is authorized to access stored data, and has the following features:
• Strong session keys are provided independently of the strength of the password.
• The entropy of the password used to authenticate the inspection system can be very low (e.g.
6 digits are sufficient in general).
33 PACE supports, as part of the protocol execution, different mappings of the generator of the
cryptographic group contained in the selected domain parameters into an ephemeral one.
34 The following mappings are supported by the TOE:
• Generic Mapping, based on a Diffie-Hellman key agreement
• Integrated Mapping, based on a direct mapping of a nonce into an element of the
cryptographic group
• Chip Authentication Mapping, which extends the Generic Mapping and integrates Chip
Authentication into the PACE protocol.
35 All the algorithm combinations (i.e. key agreement algorithms, mapping algorithms, block
ciphers) and the standardized domain parameters specified in [ICAO-9303] are supported for
PACE authentication.

36 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).

- 13 -
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) >
37 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
Document Security Object (SOD) has been read from a genuine IC.
< EAC(Extended Access Control) >
▢ EAC-CA
38 Chip Authentication is an ephemeral-static Diffie-Hellman key agreement protocol that provides
secure communication and unilateral authentication of the the travel-document chip [ICAO-9303].
The main differences with respect to Active Authentication is :
• Besides authentication of the e-Document chip, this protocol also provides strong session
keys.
Details on Challenge Semantics are described in [ICAO-9303].
The static Chip Authentication key pair(s) must be stored on the travel-document chip.
• The private key is stored securely in the e-Document chip’s memory.
• The public key is stored in Data Group 14.
The protocol provides implicit authentication of both the travel-document chip itself and the
- Public - Security Target

- 14 -
stored data by performing secure messaging with the new session keys.
▢ EAC-TA
39 Extended Access Control is a security mechanism by means of which the travel-document chip
authenticates the inspection systems authorized to read the optional biometric reference data and
protects access to these data.
Following [EAC-TR], the ICAO application enforces Extended Access Control through the
support of Terminal Authentication v1, which is a challenge-response protocol that provides
explicit unilateral authentication of the terminal.
This protocol enables the travel document chip to verify that the terminal is entitled to access
sensitive data. Terminal Authentication also authenticates the ephemeral public key chosen by the
terminal to set up secure messaging through Chip Authentication or PACE with Chip
Authentication Mapping. In this way, the travel document chip binds the terminal’s access rights
to the secure messaging session established by the authenticated ephemeral public key of the
terminal.
In more detail, the terminal sends to the travel document chip a certificate chain that starts with
a certificate verifiable with a trusted public key stored on the chip, and ends with the terminal
certificate. Then, the terminal signs a plaintext containing its ephemeral public key with the
private key associated to its certificate, and sends the resulting signature to the travel document
chip, which authenticates the terminal by verifying the certificates and the final signature. The
read access rights to biometric data groups granted by the authentication are encoded in the
certificates. Access to Data Group 3 alone, Data Group 4 alone, or both Data Group 3 and
Data Group 4 may be granted.
Additional Security Features
40 The TOE provides crypto operation, identification, authentication and access control through
the PAC and SAC secure mechanism.
The TOE manages the function such as initialization, pre-personalization, personalization and
managing TSF such as data 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 when case

Application note 4 : Please note that user data being referred to in the table above include,
amongst other, individual-related (personal) data of the travel document holder which also
include his sensitive (i.e. biometric) data. Hence, the general security policy defined by the
current ST also secures these specific travel document holder’s data as stated in the table
above.
53 All these primary assets represent User Data in the sense of the CC.
The secondary assets also having to be protected by the TOE in order to achieve a sufficient
protection of the primary assets are:
1) Though not each data element stored on the TOE represents a secret, the ICAO Specification [ICAO-9303]
anyway requires securing their confidentiality: only terminals authenticated according to [ICAO-9303] can get
access to the user data stored. They have to be operated according to P.Terminal.
2) represents a prerequisite for anonymity of the travel document holder

Application note 5 : Since the travel document does not support any secret document holder
authentication data and the latter may reveal, if necessary, his or her verification values of the
PACE password to an authorised person or device, a successful PACE authentication of a
terminal does not unambiguously mean that the travel document holder is using TOE.
Application note 6 : travel document communication establishment authorisation data are
represented by two different entities: (i) reference information being persistently stored in the
TOE and (ii) verification information being provided as input for the TOE by a human user

Logical travel-document sensitive User Data
56 Sensitive biometric reference data (EF.DG3, EF.DG4)
57 Due to interoperability reasons the ICAO Doc 9303 [ICAO 9303] requires that Basic
Inspection Systems may have access to logical travel-document data DG1, DG2, DG5 to
DG16. The TOE is not in certified mode according to this ST, if it is accessed using BAC
[ICAO 9303] (conformance to the BAC certification [R1] is kept, though). Note that the BAC
mechanism cannot resist attacks with high attack potential (cf. [BACPasspp]). If supported, it
is therefore recommended to use PACE instead of BAC. If nevertheless BAC has to be used,
it is recommended to perform Chip Authentication v.1 before getting access to data (except
DG14), as these mechanisms are resistant to high attack potential.
58 A sensitive asset is the following more general one.
Authenticity of the travel-document’s chip
59 The authenticity of the travel-document’s chip personalised by the issuing State or
Organization for the travel-document holder is used by the presenter to prove his possession
of a genuine travel-document.
3.1.2. Subjects

61 In addition to the subjects defined by the PACE PP[PACEPassPP], this ST considers the
following subjects defined by the EAC PP[EACPassPP]:
Country Verifying Certification Authority
62 The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the
issuing State or Organization with respect to the protection of sensitive biometric reference
data stored in the travel document. The CVCA represents the country specific root of the PKI
of Inspection Systems and creates the Document Verifier Certificates within this PKI. The
updates of the public key of the CVCA are distributed in the form of Country Verifying CA
Link-Certificates.
Document Verifier
63 The Document Verifier (DV) enforces the privacy policy of the receiving State with respect to
the protection of sensitive biometric reference data to be handled by the Extended Inspection
Systems. The Document Verifier manages the authorization of the Extended Inspection Systems
for the sensitive data of the travel document in the limits provided by the issuing States or
Organizations in the form of the Document Verifier Certificates.
Terminal
64 A terminal is any technical system communicating with the TOE either through the contact
interface or through the contactless interface.
Inspection system (IS)
65 A technical system used by the border control officer of the receiving State (i) examining an
travel document presented by the traveller and verifying its authenticity and (ii) verifying the
traveller as travel document holder.
Extended Inspection System (EIS)
66 The Extended Inspection System (EIS) performs the Advanced Inspection Procedure (Figure
3-1) and therefore
(i) contains a terminal for the communication with the travel document’s chip,
(ii) implements the terminals part of PACE and/or BAC;
(iii) gets the authorization to read the logical travel document either under PACE or BAC by
optical reading the travel document providing this information.
(iv) implements the Terminal Authentication and Chip Authentication Protocols both Version

1 according to [EAC-TR] and
(v) is authorized by the issuing State or Organization through the Document Verifier of the
receiving State to read the sensitive biometric reference data.
67 Security attributes of the EIS are defined by means of the Inspection System Certificates.
BAC may only be used if supported by the TOE. If both PACE and BAC are supported by
the TOE and the BIS, PACE must be used.
Attacker
68 Additionally to the definition in Table 3-3, the definition of an attacker is refined as follows:
A threat agent trying (i) to manipulate the logical travel document without authorisation, (ii) to
read sensitive biometric reference data (i.e. EF.DG3, EF.DG4), (iii) to forge a genuine travel
documentor (iv) to trace an travel document.
Application note 7 : An impostor is attacking the inspection system as TOE IT environment
independent on using a genuine, counterfeit or forged travel document. 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
70 The assumptions describe the security aspects of the environment in which the TOE will be
used or is intended to be used.
• A.Passive_Auth PKI for Passive Authentication
71 The issuing and receiving States or Organizations establish a public key infrastructure for
passive authentication i.e. digital signature creation and verification for the logical travel

document. The issuing State or Organization runs a Certification Authority (CA) which
securely generates, stores and uses the Country Signing CA Key pair. The CA keeps the
Country Signing CA Private Key secret and is recommended to distribute the Country Signing
CA Public Key to ICAO, all receiving States maintaining its integrity.
The Document Signer
(i) generates the Document Signer Key Pair,
(ii) hands over the Document Signer Public Key to the CA for certification,
(iii) keeps the Document Signer Private Key secret and
(iv) uses securely the Document Signer Private Key for signing the Document Security
Objects of the travel documents.
The CA creates the Document Signer Certificates for the Document Signer Public Keys that
are distributed to the receiving States and Organizations. It is assumed that the Personalization
Agent ensures that the Document Security Object contains only the hash values of genuine
user data according to [ICAO-9303].
• A.Insp_Sys Inspection Systems for global interoperability
72 The Extended Inspection System (EIS) for global interoperability
(i) includes the Country Signing CA Public Key and
(ii) implements the terminal part of PACE [ICAO-9303] and/or BAC [BACPassPP].
BAC may only be used if supported by the TOE. If both PACE and BAC are supported by
the TOE and the IS, PACE must be used. The EIS reads the logical travel document under
PACE or BAC and performs the Chip Authentication v.1 to verify the logical travel document
and establishes secure messaging. The Chip Authentication Protocol v.1 is skipped if
PACE-CAM has previously been performed. EIS supports the Terminal Authentication Protocol
v.1 in order to ensure access control and is authorized by the issuing State or Organization
through the Document Verifier of the receiving State to read the sensitive biometric reference
data.
Justification : The assumption A.Insp_Sys does not confine the security objectives of the
[PACEPassPP] as it repeats the requirements of P.Terminal and adds only assumptions for
the Inspection Systems for handling the the EAC functionality of the TOE.
• A.Auth_PKI PKI for Inspection Systems
73 The issuing and receiving States or Organizations establish a public key infrastructure for card
verifiable certificates of the Extended Access Control. The Country Verifying Certification

Authorities, the Document Verifier and Extended Inspection Systems hold authentication key
pairs and certificates for their public keys encoding the access control rights. The Country
Verifying Certification Authorities of the issuing States or Organizations are signing the
certificates of the Document Verifier and the Document Verifiers are signing the certificates of
the Extended Inspection Systems of the receiving States or Organizations. The issuing States
or Organizations distribute the public keys of their Country Verifying Certification Authority to
their travel document’s chip.
Justification : This assumption only concerns the EAC part of the TOE. The issuing and use
of card verifiable certificates of the Extended Access Control is neither relevant for the PACE
part of the TOE nor will the security objectives of the [PACEPassPP] be restricted by this
assumption. For the EAC functionality of the TOE the assumption is necessary because it
covers the pre-requisite for performing the Terminal Authentication Protocol Version 1.
3.2. Threats
74 This section describes the threats to be averted by the TOE independently or in collaboration
with its IT environment. These threats result from the assets protected by the TOE and the
method of TOE’s use in the operational environment.
The TOE in collaboration with its IT environment shall avert the threats as specified below.
• T.Skimming Skimming travel-document/Capturing Card-Terminal Communication
75 Adverse action : An attacker imitates an inspection system in order to get access to the user
data stored on or transferred between the TOE and the inspecting authority
connected via the contact or contactless interfaces of the TOE.
Threat agent : having high attack potential, cannot read and does not know the correct value
of the shared password (PACE password) in advance.
Asset : confidentiality of logical travel-document data
Application note 8 : A product using BIS-BAC cannot avert this threat in the context of the
security policy defined in this ST.
Application note 9 : MRZ is printed and CAN is printed or stuck on the travel document.
Please note that neither CAN nor MRZ effectively represent secrets, but are restricted
-revealable, cf. OE.Travel_Document_Holder.

- 32 -
• T.Eavesdropping Eavesdropping on the communication between the TOE and the
PACE terminal
76 Adverse action : An attacker is listening to the communication between the travel document
and the PACE authenticated BIS-PACE in order to gain the user data
transferred between the TOE and the terminal connected.
Threat agent : having high attack potential, cannot read and does not know the correct value
of the shared password (PACE password) in advance.
Asset : confidentiality of logical travel document data
Application note 10 : A product using BIS-BAC cannot avert this threat in the context of the
security policy defined in this ST.
• T.Tracing Tracing travel document
77 Adverse action : An attacker tries to gather TOE tracing data (i.e. to trace the movement of
the travel document) unambiguously identifying it remotely by establishing
or listening to a communication via the contactless/contact interface of the
TOE.
Threat agent : having high attack potential, cannot read and does not know the correct value
of the shared password (PACE password) in advance.
Asset : privacy of the travel document holder
Application note 11 : This Threat completely covers and extends “T.Chip-ID” from BAC PP
[BACPassPP].
Application note 12 : A product using BAC (whatever the type of the inspection system is:
BIS-BAC) cannot avert this threat in the context of the security policy defined in this ST.
Application note 13 : Since the Standard Inspection Procedure does not support any unique
secret-based authentication of the travel document’s chip (no Chip Authentication or Active
Authentication), a threat like T.Counterfeit (counterfeiting travel document) cannot be averted by the
current TOE.
• T.Forgery Forgery of Data
78 Adverse action : An attacker fraudulently alters the User Data or/and TSF-data stored on the
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 33 -
travel document or/and exchanged between the TOE and the terminal
connected in order to outsmart the PACE authenticated BIS-PACE by
means of changed travel document holder’s related reference data (like
biographic or biometric data). The attacker does it in such a way that the
terminal connected perceives these modified data as authentic one.
Threat agent : having high attack potential
Asset : integrity of the travel document
• T.Abuse-Func Abuse of Functionality
79 Adverse action : An attacker may use functions of the TOE which shall not be used in TOE
operational phase in order
(i) to manipulate or to disclose the User Data stored in the TOE,
(ii) to manipulate or to disclose the TSF-data stored in the TOE or
(iii) to manipulate (bypass, deactivate or modify) soft-coded security
functionality of the TOE.
This threat addresses the misuse of the functions for the initialisation and
personalization in the operational phase after delivery to the travel document
holder.
Threat agent : having high attack potential, being in possession of one or more legitimate
travel documents
Asset : integrity and authenticity of the travel document, availability of the functionality of the
travel document
Application note 14 : Details of the relevant attack scenarios depend, for instance, on the
capabilities of the test features provided by the IC Dedicated Test Software being not
specified here.
• T.Information_Leakage Information Leakage from travel document
80 Adverse action : An attacker may exploit information leaking from the TOE during its usage
in order to disclose confidential User Data or/and TSF-data stored on the travel
document or/and exchanged between the TOE and the terminal connected. The
information leakage may be inherent in the normal operation or caused by the
attacker.
Threat agent : having high attack potential
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 34 -
Asset : confidentiality of User Data and TSF-data of the travel document
Application note 15 : 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 Differential Electromagnetic Analysis (DEMA) and
Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce
information leakage by fault injection (e.g. Differential Fault Analysis).
• T.Phys-Tamper Physical Tampering
81 Adverse action : An attacker may perform physical probing of the travel document in order
(i) to disclose the TSF-data, or
(ii) to disclose/reconstruct the TOE’s Embedded Software.
An attacker may physically modify the travel document in order to alter
(i) its security functionality (hardware and software part, as well),
(ii) the User Data or the TSF-data stored on the travel document.
Threat agent : having high attack potential, being in possession of one or more legitimate
travel documents
Asset : integrity and authenticity of the travel document, availability of the functionality of the
travel document, confidentiality of User Data and TSF-data of the travel document
Application note 16 : Physical tampering may be focused directly on the disclosure or
manipulation of the user data (e.g. the biometric reference data for the inspection system) or
the TSF data (e.g. authentication key of the travel document) 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 a direct interaction
with the travel document’s internals. Techniques commonly employed in IC failure analysis
and IC reverse engineering efforts may be used. Before that, hardware security mechanisms
and layout characteristics need to be identified. Determination of software design including
treatment of the user data and the 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.

• T.Malfunction Malfunction due to Environmental Stress
82 Adverse action : An attacker may cause a malfunction the travel document’s hardware and
Embedded Software by applying environmental stress in order to
(i) deactivate or modify security features or functionality of the TOE’
hardware or to
(ii) circumvent, deactivate or modify security functions of the TOE’s
Embedded Software.
This may be achieved e.g. by operating the travel document outside the
normal operating conditions, exploiting errors in the travel document’s
Embedded Software or misusing administrative functions. To exploit these
vulnerabilities an attacker needs information about the functional operation.
Threat agent : having high attack potential, being in possession of one or more legitimate
travel documents, having information about the functional operation
Asset : integrity and authenticity of the travel document, availability of the functionality of the
travel document, confidentiality of User Data and TSF-data of the travel document
Application note 17 : 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 threat T.Phys-Tamper) assuming a detailed knowledge about TOE’s internals.
• T.Read_Sensitive_Data Read the sensitive biometric reference data
83 Adverse action : An attacker tries to gain the sensitive biometric reference data through the
communication interface of the travel document’s chip. The attack
T.Read_Sensitive_Data is similar to the threat T.Skimming (cf. [BACPassPP]) in
respect of the attack path (communication interface) and the motivation (to get
data stored on the travel document’s chip) but differs from those in the asset
under the attack (sensitive biometric reference data vs. digital MRZ, digitized
portrait and other data), the opportunity (i.e. knowing the PACE Password) and
therefore the possible attack methods. Note, that the sensitive biometric reference
data are stored only on the travel document’s chip as private sensitive personal
data whereas the MRZ data and the portrait are visually readable on the
physical part of the travel document as well.
Threat agent : having high attack potential, knowing the PACE Password, being in possession
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 36 -
of a legitimate travel document
Asset : confidentiality of logical travel document sensitive user data (i.e. biometric reference)
• T.Counterfeit Counterfeit of travel document chip data
84 Adverse action : An attacker with high attack potential produces an unauthorized copy or
reproduction of a genuine travel document’s chip to be used as part of a
counterfeit travel document. This violates the authenticity of the travel
document’s chip used for authentication of a traveller by possession of a travel
document. The attacker may generate a new data set or extract completely or
partially the data from a genuine travel document’s chip and copy them to
another appropriate chip to imitate this genuine travel document’s chip.
Threat agent : having high attack potential, being in possession of one or more legitimate
travel documents
Asset : authenticity of user data stored on the TOE
Application note 18 : T.Forgery from the PACE PP [PACEPassPP] shall be extended by the
Extended Inspection System additionally to the PACE authenticated BIS-PACE being
outsmarted by the attacker.
3.3. Organizational Security Policies

101 The TOE must provide protection against disclosure of confidential User Data or/and TSF-data
stored and/or processed by the travel document
• 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,
• by forcing a malfunction of the TOE and/or
• by a physical manipulation of the TOE.
Application note 20 : This objective pertains to measurements with subsequent complex signal
processing due to normal operation of the TOE or operations enforced by an attacker.
• OT.Prot_Phys-Tamper Protection against Physical Tampering
102 The TOE must provide protection of confidentiality and integrity of the User Data, the
TSF-data and the travel document’s Embedded Software by means of

• controlled manipulation of memory contents (User Data, TSF-data)
with a prior
• reverse-engineering to understand the design and its properties and functionality.
• OT.Prot_Malfunction Protection against Malfunctions
103 The TOE must ensure its correct operation. The TOE must prevent its operation outside the
normal operating conditions where reliability and secure operation have not been proven or
tested. This is to prevent functional errors in the TOE. The environmental conditions may
include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency
or temperature.
104 The following TOE security objectives (OT.Identification, OT.AC_Pers) address the aspects of
identified threats to be countered involving TOE’s environment.
• OT.Identification Identification of the TOE

during personalization for travel document holder (at least EF.DG1 and EF.DG2) can not be
changed using write access after personalization.
• OT.Sens_Data_Conf Confidentiality of sensitive biometric reference data
107 The TOE must ensure the confidentiality of the sensitive biometric reference data (EF.DG3
and EF.DG4) by granting read access only to authorized Extended Inspection Systems. The
authorization of the inspection system is drawn from the Inspection System Certificate used for
the successful authentication and shall be a non-strict subset of the authorization defined in the
Document Verifier Certificate in the certificate chain to the Country Verifier Certification
Authority of the issuing State or Organization. The TOE must ensure the confidentiality of the
logical travel document data during their transmission to the Extended Inspection System. The
confidentiality of the sensitive biometric reference data shall be protected against attacks with
high attack potential.
• OT.Chip_Auth_Proof Proof of the travel document’s chip authenticity
108 The TOE must support the Inspection Systems to verify the identity and authenticity of the
travel document’s chip as issued by the identified issuing State or Organization by means of
either the PACE-CAM as defined in [ICAO-9303] or the Chip Authentication Version 1 as
defined in [EAC-TR]. The authenticity proof provided by travel document’s chip shall be
protected against attacks with high attack potential.
Application note 22 : The OT.Chip_Auth_Proof implies the travel document’s chip to have
(i) a unique identity as given by the travel document’s Document Number,
(ii) a secret to prove its identity by knowledge i.e. a private authentication key as TSF data.
The TOE shall protect this TSF data to prevent their misuse. The terminal shall have the
reference data to verify the authentication attempt of travel document’s chip i.e. a certificate
for the Chip Authentication Public Key that matches the Chip Authentication Private Key of
the travel document’s chip. This certificate is provided by
(i) the Chip Authentication Public Key (EF.DG14) in the LDS defined in [ICAO-9303] and

- 45 -
group in use according to [ICAO-9303]. The Personalization Agent has to ensure that the
Document Security Object contains only the hash values of genuine user data according to
[ICAO-9303]. The CSCA must issue its certificates exclusively to the rightful organizations
(DS) and DSs must sign exclusively correct Document Security Objects to be stored on travel
document.

them in the travel document (electronic personalization) for the travel document holder
as defined in [ICAO-9303] ,
(iv) write the document details data,
(v) write the initial TSF data,
(vi) sign the Document Security Object defined in [ICAO-9303] (in the role of a DS).
Terminal operator: Terminal’s receiving branch
• OE.Terminal Terminal operating
115 The terminal operators must operate their terminals as follows:
1) The related terminals (basic inspection systems, cf. above) are used by terminal operators
and by travel document holders as defined in [ICAO-9303].
2) The related terminals implement the terminal parts of the PACE protocol [ICAO-9303], of
the Passive Authentication [ICAO-9303] (by verification of the signature of the Document
Security Object) and use them in this order. The PACE terminal uses randomly and
(almost) uniformly selected nonces, if required by the protocols (for generating ephemeral
keys for Diffie-Hellman).
3) The related terminals need not to use any own credentials.
4) The related terminals securely store the Country Signing Public Key and the Document
Signer Public Key (in form of CCSCA and CDS) in order to enable and to perform
Passive Authentication of the travel document (determination of the authenticity of data
groups stored in the travel document, [ICAO-9303]).

5) The related terminals and their environment must ensure confidentiality and integrity of
respective data handled by them (e.g. confidentiality of the PACE passwords, integrity of
PKI certificates, etc.), where it is necessary for a secure operation of the TOE according
to the current ST.
Application note 23 : OE.Terminal completely covers and extends “OE.Exam_MRTD”,
“OE.Passive_Auth_Verif“ and “OE.Prot_Logical_MRTD” from BAC PP [BACPassPP].
Travel document holder Obligations
• OE.Travel_Document_Holder Travel document holder Obligations
116 The travel document holder may reveal, if necessary, his or her verification values of the
PACE password to an authorized person or device who definitely act according to respective
regulations and are trustworthy.
Issuing State or Organization
117 The issuing State or Organization will implement the following security objectives of the TOE
environment.
• OE.Auth_Key_Travel_Document Travel document Authentication Key
118 The issuing State or Organization has to establish the necessary public key infrastructure in
order to

data in EF.DG14 and
(iii) support inspection systems of receiving States or Organizations to verify the authenticity
of the travel document’s chip used for genuine travel document by certification of the
Chip Authentication Public Key by means of the Document Security Object.
Justification : This security objective for the operational environment is needed additionally to
those from [PACEPassPP] in order to counter the Threat T.Counterfeit as it
specifies the pre-requisite for the Chip Authentication Protocol Version 1 which
is one of the additional features of the TOE described only this Security Target.

• OE.Authoriz_Sens_Data Authorization for Use of Sensitive Biometric Reference Data
119 The issuing State or Organization has to establish the necessary public key infrastructure in
order to limit the access to sensitive biometric reference data of travel document holders to
authorized receiving States or Organizations. The Country Verifying Certification Authority of
the issuing State or Organization generates card verifiable Document Verifier Certificates for
the authorized Document Verifier only.
Justification : This security objective for the operational environment is needed in order to
handle the Threat T.Read_Sensitive_Data, the Organizational Security Policy
P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the
pre-requisite for the Terminal Authentication Protocol v.1 as it concerns the
need of an PKI for this protocol and the responsibilities of its root instance.
The Terminal Authentication Protocol v.1 is one of the additional features of
the TOE described only in this Security Target. and not in [PACEPassPP].
120 The following Security Objective for the Operational Environment is an addition to the
objectives given by the Protection Profiles to cover the Active Authentication mechanism.
• OE.Active_Auth_Key_travel-document travel-document Active Authentication key
121 The issuing State or Organization has to establish the necessary public key infrastructure in
order to
(i) generate the travel-document’s Active Authentication Key Pair,
(ii) sign and store the Active Authentication Public Key in the Active Authentication Public
Key data in EF.DG15 and
(iii) support inspection systems of receiving States or Organizations to verify the authenticity
of the travel-document’s chip used for genuine travel-document by certification of the
Active Authentication Public Key by means of the Document Security Object.
Justification : This security objective for the operational environment is needed additionally to
those from [PACEPassPP]/[EACPassPP] in order to counter the Threat
T.Counterfeit as it specifies the pre-requisite for the Active Authentication which
is one of the additional features of the TOE described only in this ST and not
in [PACEPassPP]/[EACPassPP].

Receiving State or Organization
122 The receiving State or Organization will implement the following security objectives of the
TOE environment.
• OE.Exam_Travel_Document Examination of the physical part of the travel document
123 The inspection system of the receiving State or Organization must examine the travel
document presented by the traveller to verify its authenticity by means of the physical security
measures and to detect any manipulation of the physical part of the travel document. The
Basic Inspection System for global interoperability
(i) includes the Country Signing CA Public Key and the Document Signer Public Key of each
issuing State or Organization, and
(ii) implements the terminal part of PACE and/or the Basic Access Control. Extended
Inspection Systems perform additionally to these points the Chip Authentication as either
part of PACE-CAM or as Chip Authentication Protocol Version 1 to verify the
Authenticity of the presented travel document’s chip.
Justification : This security objective for the operational environment is needed in order to
handle the Threat T.Counterfeit and the Assumption A.Insp_Sys by demanding
the Inspection System to perform the Chip Authentication as either part of
PACE-CAM or as Chip Authentication protocol v.1. OE.Exam_Travel_Document
also repeats partly the requirements from OE.Terminal and therefore also counters
T.Forgery and A.Passive_Auth. This is done because this ST introduces the
Extended Inspection System which is needed to handle the additional features of
a travel document with Extended Access Control.
• OE.Prot_Logical_Travel_Document Protection of data from the logical travel document
124 The inspection system of the receiving State or Organization ensures the confidentiality and
integrity of the data read from the logical travel document. The inspection system will prevent
eavesdropping to their communication with the TOE before secure messaging is successfully
established based on the Chip Authentication.
Justification : This security objective for the operational environment is needed in order to
handle the Assumption A.Insp_Sys by requiring the Inspection System to
perform secure messaging based on the Chip Authentication.

• OE.Ext_Insp_Systems Authorization of Extended Inspection Systems
125 The Document Verifier of receiving States or Organizations authorizes Extended Inspection
Systems by creation of Inspection System Certificates for access to sensitive biometric
reference data of the logical travel document. The Extended Inspection System authenticates
themselves to the travel document’s chip for access to the sensitive biometric reference data
with its private Terminal Authentication Key and its Inspection System Certificate.
Justification : This security objective for the operational environment is needed in order to
handle the Threat T.Read_Sensitive_Data, the Organizational Security Policy
P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the pre-requisite
for the Terminal Authentication Protocol v.1 as it concerns the responsibilities of
the Document Verifier instance and the Inspection Systems.
4.3. Security Objective Rationale
126 The following table 4-1 provides an overview for security objectives coverage (TOE and its
environment). It shows that all threats and OSPs are addressed by the security objectives. It
also shows that all assumptions are addressed by the security objectives for the TOE
environment.
127 A detailed justification required for suitability of the security objectives to coup with the
security problem definition is given below.
128 The threat T.Skimming addresses accessing the User Data (stored on the TOE or transferred
between the TOE and the terminal) using the TOE’s contactless or contact interface. This
threat is countered by the security objectives OT.Data_Integrity, OT.Data_Authenticity and
OT.Data_Confidentiality through the PACE authentication. The objective
OE.Travel_Document_Holder ensures that a PACE session can only be established either by
the travel document holder itself or by an authorised person or device, and, hence, cannot be
captured by an attacker.
129 The threat T.Eavesdropping addresses listening to the communication between the TOE and a
rightful terminal in order to gain the User Data transferred there. This threat is countered by
the security objective OT.Data_Confidentiality through a trusted channel based on the PACE
authentication.

130 The threat T.Tracing addresses gathering TOE tracing data identifying it remotely by
establishing or listening to a communication via the contactless/contact interface of the TOE,
whereby the attacker does not a priori know the correct values of the PACE password. This
threat is directly countered by security objectives OT.Tracing (no gathering TOE tracing data)
and OE.Travel document-Holder (the attacker does not a priori know the correct values of the
shared passwords).
131 The threat T.Forgery addresses the fraudulent, complete or partial alteration of the User Data
or/and TSF-data stored on the TOE or/and exchanged between the TOE and the terminal. The

(Table 4-1) security objectives rationale
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 51 -
security objective OT.AC_Pers requires the TOE to limit the write access for the travel
document to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will
protect the integrity and authenticity of the stored and exchanged User Data or/and TSF-data
as aimed by the security objectives OT.Data_Integrity and OT.Data_Authenticity, respectively.
The objectives OT.Prot_Phys-Tamper and OT.Prot_Abuse-Func contribute to protecting integrity
of the User Data or/and TSF-data stored on the TOE. A terminal operator operating his
terminals according to OE.Terminal and performing the Passive Authentication using the
Document Security Object as aimed by OE.Passive_Auth_Sign will be able to effectively
verify integrity and authenticity of the data received from the TOE. The examination of the
presented MRTD passport book according to OE.Exam_Travel_Document “Examination of the
physical part of the travel document” shall ensure its authenticity by means of the physical
security measures and detect any manipulation of the physical part of the travel document.
132 The threat T.Abuse-Func addresses attacks of misusing TOE’s functionality to manipulate or to
disclosure the stored User- or TSF-data as well as to disable or to bypass the soft-coded
security functionality. The security objective OT.Prot_Abuse-Func ensures that the usage of
functions having not to be used in the operational phase is effectively prevented.
133 The threats T.Information_Leakage, T.Phys-Tamper and T.Malfunction are typical for integrated
circuits like smart cards under direct attack with high attack potential. The protection of the
TOE against these threats is obviously addressed by the directly related security objectives
OT.Prot_Inf_Leak, OT.Prot_Phys-Tamper and OT.Prot_Malfunction, respectively.
134 The threat T.Counterfeit “Counterfeit of travel document chip data” addresses the attack of
unauthorized copy or reproduction of the genuine travel document's chip. This attack is
thwarted by chip an identification and authenticity proof required by OT.Chip_Auth_Proof
“Proof of travel document’s chip authentication” using an authentication key pair to be
generated by the issuing State or Organization. The Public Chip Authentication Key has to be
written into EF.DG14 and signed by means of Documents Security Objects as demanded by
OE.Auth_Key_Travel_Document “Travel document Authentication Key”. According to
OE.Exam_Travel_Document “Examination of the physical part of the travel document” the
General Inspection system has to perform the Chip Authentication as either part of
PACE-CAM or as Chip Authentication Protocol Version 1 to verify the authenticity of the
travel document’s chip.
In addition, the threat T.Counterfeit “Counterfeit of the travel document chip data” is
countered by chip an identification and authenticity proof required by OT.Active_Auth_Proof
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 52 -
“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”.
135 The OSP P.Manufact “Manufacturing of the travel document’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.
136 The OSP P.Pre-Operational is enforced by the following security objectives: OT.Identification
is affine to the OSP’s property ‘traceability before the operational phase’ OT.AC_Pers and
OE.Personalization together enforce the OSP’s properties ‘correctness of the User- and the
TSF-data stored’ and ‘authorisation of Personalization Agents’ : OE.Legislative_Compliance is
affine to the OSP’s property ‘compliance with laws and regulations’.
137 The OSP P.Card_PKI is enforced by establishing the issuing PKI branch as aimed by the
objectives OE.Passive_Auth_Sign (for the Document Security Object).
138 The OSP P.Trustworthy_PKI is enforced by OE.Passive_Auth_Sign (for CSCA, issuing PKI
branch).
139 The OSP P.Personalization “Personalization of the travel document by issuing State or
Organization only” addresses the
(i) the enrolment of the logical travel document by the Personalization Agent as described
in the security objective for the TOE environment OE.Personalization “Personalization of
logical travel document”, 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 travel document”.
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 the management of TSF to the
Personalization Agent.
140 The OSP P.Sensitive_Data “Privacy of sensitive biometric reference data” is fulfilled and the
threat T.Read_Sensitive_Data “Read the sensitive biometric reference data” is countered by the
- Public - Security Target
Copyright Ⓒ 2025 KOMSCO. All rights reserved EPS-05-AN-ST-SAC(Lite)
- 53 -
TOE-objective OT.Sens_Data_Conf “Confidentiality of sensitive biometric reference data”
requiring that read access to EF.DG3 and EF.DG4 (containing the sensitive biometric reference
data) is only granted to authorized inspection systems. Furthermore it is required that the
transmission of these data ensures the data’s confidentiality. The authorization bases on
Document Verifier certificates issued by the issuing State or Organization as required by
OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”. The
Document Verifier of the receiving State has to authorize Extended Inspection Systems by
creating appropriate Inspection System certificates for access to the sensitive biometric
reference data as demanded by OE.Ext_Insp_Systems “Authorization of Extended Inspection
Systems”.
141 The OSP P.Terminal “Abilities and trustworthiness of terminals” is countered by the security
objective OE.Exam_Travel_Document additionally to the security objectives from PACE PP
[PACEPassPP] OE.Exam_Travel_Document enforces the terminals to perform the terminal part
of the PACE protocol. and also, The OSP P.Terminal is obviously enforced by the objective
OE.Terminal, whereby the one-to-one mapping between the related properties is applicable.
142 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”.
143 The examination of the travel document addressed by the assumption A.Insp_Sys “Inspection
Systems for global interoperability” is covered by the security objectives for the TOE
environment OE.Exam_Travel_Document “Examination of the physical part of the travel
document” which requires the inspection system to examine physically the travel document, the
Basic Inspection System to implement the Basic Access Control, or the Basic Inspection
System with PACE to implement the PACE, and the Extended Inspection Systems to
implement and to perform the Chip Authentication Protocol Version 1 to verify the
Authenticity of the presented travel document’s chip. The security objectives for the TOE
environment OE.Prot_Logical_Travel_Document “Protection of data from the logical travel
document” require the Inspection System to protect the logical travel document data during the
transmission and the internal handling.

144 The assumption A.Passive_Auth “PKI for Passive Authentication” is directly covered by the
security objective for the TOE environment OE.Passive_Auth_Sign “Authentication of travel
document by Signature” from PACE PP [PACEPassPP] covering the necessary procedures for
the Country Signing CA Key Pair and the Document Signer Key Pairs. The implementation of
the signature verification procedures is covered by OE.Exam_Travel_Document “Examination of
the physical part of the travel document”.
145 The assumption A.Auth_PKI “PKI for Inspection Systems” is covered by the security objective for the
TOE environment OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”
requires the CVCA to limit the read access to sensitive biometrics by issuing Document Verifier
certificates for authorized receiving States or Organizations only. The Document Verifier of the
receiving State is required by OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems” to
authorize Extended Inspection Systems by creating Inspection System Certificates. Therefore, the
receiving issuing State or Organization has to establish the necessary public key infrastructure.

5. Extended Components Definition (ASE_ECD.1)
146 This ST uses components defined in the protection profile [EACPassPP] and [PACEPassPP] as
extensions to CC part 2
5.1. Definition of the family FAU_SAS
147 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.

6. Security Requirements (ASE_REQ.2)
148 This part of the ST defines the detailed security requirements that shall be satisfied by the
TOE. The statement of TOE security requirements shall define the functional and assurance
security requirements that the TOE needs to satisfy in order to meet the security objectives
for the TOE.
149 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.
150 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.
151 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 .
152 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 .
153 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.
154 The definition of the subjects “Manufacturer”, “Personalization Agent”, “Extended Inspection
System”, “Country Verifying Certification Authority”, “Document Verifier” 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 either in section 8 or in the
following table. The operations “write”, “modify”, “read” and “disable read access” are used in
accordance with the general linguistic usage. The operations “store”, “create”, “transmit”,
“receive”, “establish communication channel”, “authenticate” and “re-authenticate” are originally
taken from [CC]. The operation “load” is synonymous to “import” used in [CC].

Application note 25 : The Manufacturer role is the default user identity assumed by the TOE
in the life phase ‘manufacturing’. The IC manufacturer and the travel document manufacturer
in the Manufacturer role write the Initialization and/or Pre-personalization Data as TSF-data
into the TOE. The audit records are usually write-only-once data of the travel document (see
FMT_MTD.1/INI_ENA, FMT_MTD.1/INI_DIS). Please note that there could also be such audit
records which cannot be read out, but directly used by the TOE.
6.1.2. Class FCS Cryptographic Support
159 The TOE shall meet the requirement “Cryptographic key generation (FCS_CKM.1)” as

Application note 80 : The TOE may restrict the ability to write the Initialization Data and the
Pre-personalization Data by (i) allowing writing these data only once and (ii) blocking the role
Manufacturer at the end of the manufacturing phase. The Manufacturer may write the
Initialization Data (as required by FAU_SAS.1) including, but being not limited to a unique
identification of the IC being used to trace the IC in the life phases ‘manu-facturing’ and
‘issuing’, but being not needed and may be misused in the ‘operational use’. Therefore, the
read and use access shall be blocked in the ‘operational use’ by the Personalization Agent,
when he switches the TOE from the life phase ‘issuing’ to the life phase ‘operational use’.

6.1.5. Class FPT Protection of the Security Functions
231 The TOE shall prevent inherent and forced illicit information leakage for User Data and
TSFdata.The security functional requirement FPT_EMS.1 addresses the inherent leakage. With
respect to the forced leakage they have to be considered in combination with the security
functional requirements “Failure with preservation of secure state (FPT_FLS.1)” and “TSF
testing (FPT_TST.1)” on the one hand and “Resistance to physical attack (FPT_PHP.3)” on
the other. The SFRs “Limited capabilities (FMT_LIM.1)”, “Limited availability (FMT_LIM.2)”
and “Resistance to physical attack (FPT_PHP.3)” together with the SAR “Security architecture
description” (ADV_ARC.1) prevent bypassing, deactivation and manipulation of the security
features or misuse of TOE security functionality.
