1 ST Introduction
This chapter presents Security Target (ST) and TOE identification information and a general
overview of the ST. An ST contains the information technology (IT) security requirements of
an identified Target of Evaluation (TOE) and specifies the functional and assurance security
measures offered by that TOE to meet stated requirements. An ST principally defines:
a) A security problem expressed as a set of assumptions about the security aspects of
the environment, a list of threats that the TOE is intended to counter, and any known
rules with which the TOE must comply (chapter 3, Security Problem Definition)
b) A set of security objectives and a set of security requirements to address the security
problem (chapters 4 and 6, Security Objectives and IT Security Requirements,
respectively).
c) The IT security functions provided by the TOE that meet the set of requirements
(chapter 7, TOE Summary Specification).
1.1 ST and TOE Reference

1.2 TOE Overview
The Target of Evaluation (TOE) addressed by this Security Target (ST) is the
Bundesdruckerei Document Application. In the following this application is called “Document
Application”.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 7/55
The Document Application is a library, which is used via a static link by an application
running on an Inspection System (IS), called EAC-Module. The library is used to read and
update the electronic data of the German identification card (“Personalausweis (PA)”) and
electronic resident permit (“elektronischer Aufenthaltstitel (eAT)”) as well as to verify the
document’s authenticity and the integrity of its data.
The TOE is applied in registration offices to allow card holders to verify that their PA or eAT
is working correctly. It is further possible to update the address information of the card
holder, the card holder’s PIN for eID applications, and the community ID
(“Gemeindeschlüssel”). In addition, the eID application functionality of the PA or eAT can be
activated or deactivated.
More details on the TOE Overview can be found in [PP] section 1.2. The Document
Application will be used as the main part of an IS as described in this section.
Necessary protocols for the communication of the TOE with the electronic Machine Readable
Travel Documents (eMRTD) like the PA or eAT are described in [ICAO_9303] and [TR-
03110].
1.3 TOE Description
This chapter provides context for the TOE evaluation by identifying the product type and
describing the evaluated configuration. The main purpose of this chapter is to bind the TOE
in physical and logical terms.
The chapter starts with a description of the product type, the supported protocols and modes
of operation. Afterwards it introduces the physical and logical scope of the TOE.
1.3.1 Product Type
The product type of the Target of Evaluation (TOE) described in this ST is an Inspection
System (IS) used to read and modify data records on the electronic Machine Readable
Travel Documents and to verify the integrity and authenticity of that data.
1.3.2 Supported protocols
The TOE implements the following protocols to communicate with eMRTDs:
Protocol Name Specified in Use Case
BAC [ICAO_9303] Confidentiality of submitted chip data,
authentication and secure channels
Chip Authentication [EAC1.11]
[EAC2.05]
Authenticity of eMRTD chip, secure channels,

1.3.4 Physical Scope and Boundary of the TOE
Figure 1: TOE demarcation
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 9/55
The physical scope and boundary of the TOE is depicted in Figure 1. The TOE is the
document application of the product EAC-Module and is therefore software only. It is
accompanied by its dedicated guidance documentation.
The platform for the TOE is the VISOTEC® Änderungsterminal Firmware, which is based on
a Linux Kernel of the 2.6 series and the GNU libc library. The underlying hardware is a 32 bit
embedded controller.
The TOE relies on a security controller that performs the cryptographic operations for
Terminal Authentication and that stores the necessary private key. All other cryptographic
operations (e.g. for the other protocols) are performed in software by the TOE itself. Private
keys that are used for other authentication mechanisms are stored temporarily in the volatile
memory of the TOE.
The following list shows the other components in the environment of the TOE that the TOE
relies on:
• A PIN pad and a display for user interaction
• Proximity coupling device (PCD) for communication with the eMRTDs
• Smartcard reader for authentication of users with security tokens
• Security Controller for cryptographic operations
• Ethernet network interface for certificate and CRL download
• USB interface to read/write data groups
• System Clock
• Storages for audit data and certificates/CRLs
The components are physically separated into the EAC-Module and the PIN pad / Reader
module.
1.3.5 Logical Scope and Boundary of the TOE
The logical scope of the TOE is best described by its main security functionality:
• Secure encrypted and authenticated communication with eMRTDs,
• Protection of sensitive personal data from eMRTDs and TSF data,
• Deterministic random number generation,
• Management including initiating secure firmware update, and
• Generation of audit data.
The TOE uses the following security functionality of the environment:
• Authentication of users,
• Installation of firmware update,
• Secure storage and usage of private keys,
• Entropy source for random number generation,
• Storage of audit data, and
• Physical protection.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 10/55
1.4 Conventions
For this Security Target the following conventions are used:
The CC allows several operations to be performed on functional requirements; refinement,
selection, assignment, and iteration are defined in chapter C.4 of Part 1 of the CC. Each of
these operations is used in this ST.
The refinement operation is used to add detail to a requirement, and thus further restricts a
requirement. Refinement of security requirements is denoted by the word “refinement” in
bold text and the added/changed words are in bold text. In cases where words from a CC
requirement were deleted, a separate attachment indicates the words that were removed.
The selection operation is used to select one or more options provided by the CC in stating
a requirement. Selections that have been made by the PP authors are denoted as underlined
text. Selections that have been made by the ST author appear in square brackets, and are
italicized and underlined.
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. Assignments that have been made by the ST author
appear in square brackets and are italicized.
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.
The CC paradigm also allows protection profile and security target authors to create their
own requirements. Such requirements are termed ‘explicit requirements’ and are permitted if
the CC does not offer suitable requirements to meet the authors’ needs. Explicit
requirements must be identified and are required to use the CC class/family/component
model in articulating the requirements.
An overview of keys and certificates used can be found in [PP] chapter 6.

2 Conformance Claims
2.1 CC Conformance Claim
This Security Target claims to be
• CC Part 2 (Version 3.1, Revision 3, July 2009) extended as functional components
as defined in part II of [CC] and also the extended functional components
FCS_RND.1 and FIA_API.1 as defined in [PP] have been used.
• CC Part 3 (Version 3.1, Revision 3, July 2009) conformant as only assurance
components as defined in part III of [CC] have been used.
Further this Security Target claims to be conformant to the Security Assurance Requirements
package EAL 3.
2.2 PP Conformance Claim
This Security Target claims conformance to the Common Criteria Protection Profile for
Inspection Systems (IS) [PP].
The Protection Profile requires a demonstrable conformance only. However, this Security
Target claims strict conformance to the Protection Profile as it completely includes the
statement of security problem definition of the PP.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 12/55
3 Security Problem Definition
This chapter describes
• the assets that have to be protected by the TOE,
• assumptions about the environment of the TOE,
• threats against those assets, and
• organisational security policies that TOE shall comply with.
3.1 External entities
The following external entities interact with the TOE:
Operator (E1)
The Operator is the user of the TOE (e.g. employee of a governmental organization).
Administrator (E2)
The Administrator is a person who administrates the TOE and who is able to access the TOE
on a dedicated service interface to change security attributes of the TOE Security
Functionality (TSF).
Revisor (E3)
The Revisor is a person who is able to access the TOE on a dedicated service interface to
inspect the log files of the TOE.
Attacker (E4)
A person who tries to manipulate the TOE in order to change its behaviour without being
authorized or tries to provide the TOE with false information (this may be a forged certificate
or a false software update, etc.) is an Attacker.
electronic Identity Document (E5)
An MRTD, ePass, PA or eAT supporting cryptographic mechanisms which allows the
Inspection System to check their Integrity and Authenticity. The Electronic Identity Document
is presented to the Inspection System which then communicates with the TOE secured by
cryptographic means.
electronic Identity Document presenter (E6)
Person presenting the electronic Identity Document to the inspection system and claiming
the identity of the electronic Identity Document holder.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 13/55
Private Key Storage (E7)
Storage of the Inspection System's Key Pairs. The Key Pairs are used for the Terminal
Authentication Protocol. The Private Key Store is protected by further security measures in
the environment of the TOE (security controller) to enforce the protection needs of the
Inspection System's Key Pairs.
Certificate / CRL storage (E8)
The Certificate and CRL storage hold the certificates and CRLs representing the PKI for the
Passive Authentication and Terminal Authentication. Furthermore the storage maintains
specific certificates and/or specific public keys the EAC-Module implicitly trusts in. These
specific certificates and/or specific public keys are the root keys of the PKI. The Certificate
and CRL storage is protected by further security measures to enforce the protection needs of
the Certificates and CRLs.
Logfile storage (E9)
The Logfile storage holds the logfile entries generated by the TOE. The Logfile storage is
protected by further security measures to enforce the protection needs of the Logfile entries.
Proximity Coupling Device (PCD) (E10)
The PCD realizes the interface between the electronic Identity Document and the TOE. The
PCD consists of a contact-less interface and some further electronic components
implementing appropriate transmission protocols allowing communication between the PCD
and electronic Identity Documents. Furthermore the PCD provides an interface to the TOE
finally allowing the communication between the TOE and electronic Identity Document.
PIN pad (E11)
The PIN pad provides necessary input data to the TOE. For example, it is used for entering
the shared secret for PACE authentication.
Display (E12)
The display presents results of the Inspection Process as well as further information obtained
during the process to the user of the TOE (E1 and/or E2). It is further used for general user
interaction/feedback during management of the TOE.
electronic Identity Document holder (E13)
The rightful/legitimated holder of the electronic Identity Document for whom the issuing
authority personalised the electronic Identity Document.
3.2 Assets
The assets to be protected by the TOE and its environment are as follows:
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 14/55
Chip password (O1)
The chip password is used to get basic access to the chip data. In case of an eMRTD
according to [ICAO_9303] this would be a part of the MRZ (Machine Readable Zone), for
other electronic identity documents this could be e.g. another password printed on the
document (as CAN in [EAC2.05]). Dependent upon the form of the chip password it can be
read by an OCR Reader or must be typed in on a keyboard, etc.
Required Protection: Integrity, Confidentiality

Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 16/55
3.3 Assumptions
In the following the assumptions about the environment of the TOE are described:
A.SecureBoot
It is assumed that the environment provides mechanisms to boot the operating system
containing the Document Application and the device drivers in a secure way so that an initial
secure state without protection compromise is guaranteed. Furthermore it is assumed the
secure boot process provides an integrity check of the TSF.
A.PhysicalTamper
It is assumed that the EAC-Module is protected against physical tamper by placing additional
devices on the EAC-Module as e.g. key loggers or removing the whole terminal or parts of it
concerning low level attacks.
A.SecureAdministration
It is assumed that the administration of the EAC-Module as well as of the TOE installed at
the EAC-Module is maintained securely. This includes that only authorised personnel is
allowed to administer the EAC-Module respectively the TOE and that no Malware will be
installed at the EAC-Module.
A.TrainedUser
It is assumed that the authorised Users of the TOE, Operator (E1) and Administrator (E2),
are well trained. This includes that no user will intentionally compromise the TOE installation
as well as the assets secured by the TOE and the TOE environment.
A.SecureEnvironment
It is assumed that the TOE environment at the EAC-Module is secure. This assumption
includes that no other application - or also parts of the Operating System - installed at the
inspection system compromise sensitive data, manipulate sensitive data or the results of the
MRTD authentication, or even try to penetrate the TOE itself with the intention to affect the
TOE's security functionality maliciously. Furthermore this includes also that components of
the EAC-Module the TOE relies on work properly as intended (e.g. the Output of the EAC-
Module prints the MRTD data as handed over by the TOE, the identification and
authentication mechanism of EAC-Module – provided by the operating environment – is
effective, the security measures of the Certificate/ CRL, Private Key and Logfile storage are
in place, etc.).
The firmware update is initiated by the TOE and securely performed by the
environment. Therefore, the operating system and the firmware update component
residing in the TOE environment are assumed to be trustworthy.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 17/55
A.DisplayShield
It is assumed that the EAC-Module is installed in such a way that the sensitive data printed at
the output device are visible only to authorised persons.
A.ValidKeyAndCertificateData
It is assumed that all further data stored in TOE related components are securely maintained.
This includes that they are generated and imported according to their protection
requirements as defined in section 3.2.
A.PKI
It is assumed that the environment provides a Public Key infrastructure for EAC and Passive
Authentication.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 18/55
3.4 Threats
This section describes the threats to be averted by the TOE independently or in collaboration
with its IT environment. These threats result from the TOE method of use in the operational
environment and the assets stored in or protected by the TOE.
T.ForgeMRTD – Acceptance of forged MRTD
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 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 traveller. The attacker may
alter the printed portrait and the digitized portrait to overcome the visual
inspection of the inspection officer and the automated biometric
authentication mechanism by face recognition. The attacker may alter the
biometric reference data to defeat automated biometric authentication
mechanism of the inspection system. The attacker may combine data
groups of different logical MRTDs to create a new forged MRTD, e.g. the
attacker writes the digitized portrait and optional biometric reference
finger data read from the logical MRTD of a traveller into another MRTD’s
chip leaving their digital MRZ unchanged to claim the identity of the
holder of this MRTD.
Threat agent: An attacker (E4) having basic attack potential, being in possession of one
or more legitimate MRTDs
Asset: Protocol Results (O12)
T.DataCompromise – Compromise of sensitive MRTD Data
Adverse action: An attacker (E4) could pretend to be an operator (E1) using the IS and
the TOE to read sensitive data (O2 and O3) from electronic identity
documents.
Threat agent: An attacker (E4) having basic attack potential, not knowing the optically
readable MRZ data printed on the MRTD data page in advance nor
having access to the MRTDs accessed.
Asset: Personal Chip Data (O2), Sensitive Chip Data (O3)
T.FakedLogfileEntries Spoofing of Logfile Information
Adverse action: An attacker (E4) could try to manipulate the logfiles (O10) to cover
information about the TOE installation which might be changed
maliciously.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 19/55
Threat agent: An attacker (E4) having basic attack potential, having physical access
to the EAC-Module.
Asset: Log File entries (O9)
T.Eavesdropping Eavesdropping of sensitive chip data
Adverse action: An attacker (E4) could eavesdrop sensitive and personal chip data (O2
and O3) transmitted between MRTD Chip and document reading
application.
Threat agent: An attacker (E4) having basic attack potential, having physical access
to the EAC-Module.
Asset: Personal Chip Data (O2), Sensitive Chip Data (O3)
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 20/55
3.5 Organisational Security Policies
P.CheckTerminal
The integrity of the entire IS hardware shall be checked regularly by the Operator (E1).
The Case of the IS should be sealed in a manner that the Operator can verify at the
beginning of his duty that the terminal is genuine. Therefore a unique label is necessary so
that an exchange of the whole IS or manipulation on cable connections can be detected.
The stored log data shall be revised regularly to discover malfunctions or attacks. This shall
be done by a revisor (E3) who is not the same person as the administrator (E2).
P.Date
The Operator (E1) must perform a daily check of the system date. Therefore he has to use a
reliable reference (e.g. DCF-77 Clock, GPS Clock, etc.). Especially in the context of
certificate validation it must be assured that the system date is correct.
P.ChipPassword
The Operator (E1) must ensure during a reading or updating operation that any person who
is not authorised to know the chip password (O1) is not able to skim it. Therefore a special
distance between the IS and waiting customers shall be enforced3
.
P.CertifiedPrivateKeyStore
It has to be assured that the Private Key Storage is a device certified according to minimum
EAL4.
P.PrivateKeyStore
The Private Key Storage has to authenticate with the electronic Identity Document (E5) via
the Terminal Authentication Protocol.
3
The specific distance between the IS and waiting customers is defined in the guidance document.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 21/55
4 Security Objectives
The purpose of the security objectives is to detail the planned response to a security problem
or threat. This chapter describes the security objectives for the TOE and its operational
environment.
Aspects of the security objectives that are not stated in [PP] but used in ST are marked bold.
4.1 Security Objectives for the TOE
O.AdminAuthorisation
The TOE must provide an administration interface. The TOE shall use the result of an
Identification and Authentication mechanism to enforce that only authorised administrators
are allowed to make use of the administration interface to change the TOE's configuration
(including update of the TOE's current version). The TOE may use those Identification and
Authentication mechanisms provided by the operating system.
O.OperatorAuthorisation
If personal chip data (O2) and/or sensitive chip data (O3) shall be read the TOE must
enforce the authentication of the operator (E1) as an authorised person. The TOE shall use
the result of an Identification and Authentication mechanism to enforce the operator's
authorisation. The TOE may use those Identification and Authentication mechanisms
provided by the operating system.
O.UpdatingSoftware
The TOE shall only accept signed updates with a higher or equal version number compared
to the current version.
O.DisplayVersion
The TSF must be able to maintain version information about the TOE itself and must be able
to present this evidence to external entities allowing those entities to verify the version of the
TSF itself.
O.Logdata
The TOE shall write log data at least about every change in configuration or software
updates.
O.DeletionEphemeralData
The TOE shall delete ephemeral data after every completed or aborted reading/updating
process in a secure way (data shall be overwritten). This includes all data read from the chip
(O1, O2, O3), every generated random number (O6), ephemeral key and session key (O5)
and sensitive input data (O11).
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 22/55
O.ProtocolMRTD
The TOE shall implement the protocol according to the specifications [EAC2.05] and/or
[EAC1.11] in realisation of an inspection system. This includes the Security Mechanisms
Basic Access Control (BAC), Password Authenticated Connection Establishment (PACE),
Chip Authentication and Passive Authentication.
The TOE shall enforce the establishment of secure messaging between the electronic
identity document's chip and Document Application in dependency on the protocols (see
[PP, 1.2.4]) supported by the chip.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 23/55
4.2 Security Objectives for the operational Environment
OE.SecureBoot
The environment must provide mechanisms to boot the EAC-Module OS and the device
drivers in a secure way so that an initial secure state without protection compromise is
guaranteed.
OE.SignedCertsAndCRLs
The environment shall make sure that only certificates, certificate-lists and CRLs (O7, O8)
from the certificate storage are provided to the TOE which are signed by the CSCA or a key
signed by the CSCA of the operating state.
OE.PKI
The environment must provide Public Key Infrastructures for EAC and Passive
Authentication according to the specifications in [ICAO_9303], [EAC2.05] and/or [EAC1.11]
depending on the used protocols.
Each PKI environment must provide a Certificate Policy.
OE.TA
The environment of the TOE shall implement the cryptographic mechanism Terminal
Authentication as part of EAC. This includes maintaining of the Terminal's Private Key and
the implementation of the security protocol Terminal Authentication.
OE.SecureAdministration
The administration of the EAC-Module as well as the TOE itself shall be maintained securely.
Only authorised personnel shall be allowed to administer the EAC-Module and the TOE. The
administration personnel will not install any malicious soft- or hardware at the inspection
system.
OE.TrainedUser
The Users – Operators and Administrators – of the EAC-Module shall be well trained in a
sense not to intentionally compromise neither the TOE installation itself nor the assets
secured by the TOE and the TOE environment.
OE.SecureEnvironment
The TOE environment shall be secure. For example, the firmware update is initiated by
the TOE and securely performed by the environment. Therefore, the operating system
and the firmware update component residing in the TOE environment shall be
trustworthy. Other applications installed at the EAC-Module as well as the Operating
System itself shall not compromise and/or manipulate sensitive data and shall not penetrate
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 24/55
the TOE. The Secure Environment shall ensure that the results of the MRTD authentication
are displayed to the Operator unaltered. Further components of the EAC-Module the TOE
relies on, the Certificate and CRL Store respectively, the private Key Storage and the
identification/authentication mechanism of the operational environment shall work properly as
intended:
– The identification/authentication mechanism of the operating system shall be effective and
shall provide information to the TOE which allows the TOE to assign roles to identities.
– The Security Measures of the Certificate and CRL Storage respectively and the Private
Key Storage shall be in place.
– The operational environment shall provide a secure storage for logfiles which enforces
access control and provides secure messaging.4
The Private Key Store shall be certified according to the Common Criteria at least with the
assurance level EAL4.
OE.ComponentCommunication
The communication between the TOE and the logfile storage, the private key storage and the
certificate / CRL storage shall be secured for the assets transferred according to the the
required protection as defined in chapter 3.2.
E.g. the communication between TOE and the Private Key Store shall be secured against
attacks on the confidentiality, authenticity and integrity of the exchanged messages. The
communication between the TOE and the log file storage shall be secured against attacks on
authenticity and integrity.
OE.DisplayShield
The Display of the EAC-Module shall be installed in a manner that the output of sensitive
data can't be observed by unauthorised persons.
OE.CheckTerminalIntegrity
The integrity of the entire IS hardware shall be checked regularly by Operator (E1) .The
housing of the IS should be sealed in a manner that the operator can verify at the beginning
of his duty that the terminal is authentic. Therefore a unique label is necessary so that an
exchange of the whole IS or manipulation on cable connections can be detected. The stored
log data shall be revised regularly to discover malfunctions or attacks. This shall be done by
a revisor (E3) who is not the same person as the administrator (E2).
OE.Date
4
The log file storage will be implemented within the chassis of the EAC-Module, which provides physical security
measures. Logical access to the log file storage will be limited to the Revisor role only.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 25/55
The operator (E1) shall check the correctness of the current date and time of the TOE at the
beginning of his duty. For this the Operator has to use a reliable reference (e.g. DCF-77
Clock, GPS Clock).
OE.ChipPassword
The environment must enable the Operator (E1) to ensure during a reading or updating
operation that any person who is not authorised to know the chip password (O1) is not able
to skim it. Therefore a special distance between the IS and waiting customers shall be
enforced.
OE.ValidKeyAndCertificateData
The TOE environment shall provide adequate measures to ensure the security of the further
key and certificate data – including the CRLs – during the generation and the import of such
data. In more detail the authenticity and integrity of the Private Key and the Certificates as
well as Certificate Revocation Lists shall be ensured. Furthermore for the Private Key the
confidentiality has to be ensured.

Table 2: Security Objective Rationale
4.3.1 Considerations about Threats
T.ForgeMRTD
This threat is covered by the following combination of objectives:
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 27/55
O.AdminAuthorisation makes sure that only authorised administrators can change
the configuration of the TOE. Therefore attackers cannot change the configuration in
any way which might bypass the functionality used to authenticate an MRTD.
OE.SignedCertsAndCRLs makes sure that only legitimate public keys are accepted
for the verification of signatures or certificates provided by an MRTD and/or used by
the TOE.
O.ProtocolMRTD makes sure that the TOE uses the specified cryptographic protocols
to verify the authenticity of data provided by an MRTD.
O.UpdatingSoftware makes sure that only legitimate software is used for the TOE,
which also mitigates the threat of bypassing the functionality used to authenticate an
MRTD.
OE.TA makes sure that the environment supports the advanced cryptographic
mechanism necessary for Terminal Authentication according to the respective
specifications.
T.DataCompromise
This threat is covered by the following combination of objectives:
O.AdminAuthorisation, O.OperatorAuthorisation and OE.TrainedUser together
make sure that only authorised and trained users can operate the TOE. This prevents
compromising MRTD data by operators.
OE.ComponentCommunication, OE.DisplayShield and O.DeletionEphemeralData
make sure that attackers cannot see secret data during transport between components
of the Terminal, during Display of Data or by finding old secret data in the storage of
the Terminal.
O.DisplayVersion again supports this by making sure that only legitimate software is
used.
O.UpdatingSoftware supports that attackers are not able to see secret data.
T.FakedLogFileEntries
This threat is covered as follows:
O.Logdata makes sure that log entries are written, whenever the TOE configuration is
changed or updates are installed.
OE.ComponentCommunication prevents manipulation of log file entries during their
transport between TOE and storage.
OE.SecureAdministration and OE.SecureEnvironment make sure that the log files
are not manipulated during their storage.
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 28/55
T.Eavesdropping
O.ProtocolMRTD makes sure that the specified cryptographic protocols are used for
communication between TOE and MRTD. In particular this prevents unauthorised
reading of secret data on this interface.

6 Security Requirements
This chapter defines the security requirements that shall be satisfied by the TOE or its
environment:
Common Criteria divides TOE security requirements into two categories:
• Security functional requirements (SFRs) (such as, identification and authentication,
security management, and user data protection) that the TOE and the supporting
evidence need to satisfy to meet the security objectives of the TOE.
• Security assurance requirements (SARs) that provide grounds for confidence that the
TOE and its supporting IT environment meet its security objectives (e.g.,
configuration management, testing, and vulnerability assessment).
These requirements are discussed separately within the following subchapters.

FIA_API.1/PACE Password Authenticated Connection Establishment
FIA_API.1.1/PACE The TSF shall provide a Password Authenticated Connection
Establishment according to [EAC2.05] to prove the identity of
the electronic Identity Document presenter.
Application Note: This SFR requires the TOE to implement the Password Authenticated
Connection Establishment specified in [EAC2.05].

FIA_UAU.4.1 The TSF shall prevent reuse of authentication data related to
1 Basic Access Control Authentication Mechanism
2 Password Authenticated Connection Establishment.
Application Note: The Basic Access Control Authentication Mechanism [ICAO_9303] and
the Password Authenticated Connection Establishment [EAC2.05] use a challenge RND.IFD
freshly and randomly generated by the terminal to prevent reuse of a response generated by
an MRTD’s chip and of the session keys from a successful run of the authentication protocol.
FIA_UAU.5 Multiple authentication mechanisms
FIA_UAU.5.1 The TSF shall provide
1 Basic Access Control Authentication Mechanism
2 Password Authenticated Connection Establishment
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 39/55
3 Passive Authentication
4 Chip Authentication Protocol
to support user authentication.
FIA_UAU.5.2 The TSF shall authenticate any user’s claimed identity
according to the following rules:
1 The TOE accepts the authentication attempt as MRTD
by means of the Basic Access Control Authentication
Mechanism with the Document Basic Access Keys or by
means of the Password Authenticated Connection
Establishment Authentication Mechanism.
2 After successful authentication as MRTD and until the
completion of the Chip Authentication Mechanism the
TOE accepts only response codes with correct message
authentication code sent by means of secure messaging
with keys agreed with the authenticated MRTD by means
of the Basic Access Control Authentication Mechanism
or by means of the Password Authenticated Connection
Establishment Authentication Mechanism.
3 The TOE accepts the authenticity and integrity of the

Access Control or Password Authenticated Connection
Establishment Authentication Mechanism.
4 After run of the Chip Authentication Mechanism the TOE
accepts only response codes with correct message
authentication codes sent by means of secure
messaging with keys agreed with the terminal by means
of the Chip Authentication Mechanism
Application Note: Basic Access Control Mechanism or the Password Authenticated
Connection Establishment Authentication Mechanism includes the secure messaging for all
commands and response codes exchanged after successful mutual authentication between
the inspection system and the MRTD. The inspection system shall use the Basic Access
Control Authentication Mechanism with the Document Basic Access Keys or the Password
Authenticated Connection Establishment Authentication Mechanism drawn from the second,
optical readable MRZ line and the secure messaging after the mutual authentication. The
EAC-Module and the MRTD shall use the secure messaging with the keys generated by the
Chip Authentication Mechanism after the mutual authentication.
FIA_UAU.6/BT Re-authentication – BAC/PACE
FIA_UAU.6.1/BT The TOE shall re-authenticate the user under the conditions

Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 40/55
authentication of the MRTD with Basic Access Control
or Password Authenticated Connection Establishment
Authentication Mechanism and until the completion of
the Chip Authentication Mechanism shall have a correct
MAC created by means of secure messaging keys
agreed upon by the Basic Access Control
Authentication or by the Password Authenticated
Connection Establishment Mechanism
2 Each response sent to the TOE after successful run of

Application Note: The Basic Access Control Mechanism, the Password Authenticated
Connection Establishment mechanism and the Chip Authentication Protocol specified in
[EAC2.05] and/or [EAC1.11] include secure messaging for all commands and responses
exchanged after successful authentication of the TOE. The TOE checks by secure
messaging in MAC_ENC mode each response based on Retail-MAC whether it was sent by
the successfully authenticated MRTD (see FCS_COP.1/MAC for further details). The TOE
does not accept any response with incorrect message authentication code. Therefore the
TOE re-authenticates the user for each received command and accepts only those
responses received from the authenticated user.
FIA_UID.2 User identification before any action
FIA_UID.2.1 The TSF shall require each user to be successfully identified
before allowing any other TSF-mediated actions on behalf of
that user.
Refinement: The TOE verifies the result of the identification/authentication system of the
environment by only respecting the roles supported by the TOE (see
OE.SecureEnvironment). The SFR FIA_UID.1 of [PP] was replaced by FIA_UID.2 according
to application note 27 in [PP].
6.1.5 Class Security Management (FMT)
FMT_MTD.1/Admin – Management of TSF data

FMT_MTD.1.1/Version The TSF shall restrict the ability to read the TOE version
and further TSF data: [date and time] to the Operator
and the Administrator.
FMT_SMF.1 - Specification of management functions
FMT_SMF.1.1 The TSF shall be capable of performing the following
management functions:
- modification of configuration data of the TOE
- read the TOE version
- [Verify date and time
- Initiate firmware update]
FMT_SMR.1 – Security roles

- Administrator
- Operator
- and the further authorised roles [Revisor]
FMT_SMR.1.2 The TSF shall be able to associate users with roles.
Application Note: The identification/authentication mechanism is implemented by the TOE
environment (see OE.SecureEnvironment). The TOE reuses the result of the
identification/authentication mechanism by the determination of the user's role.

Table 4: Security functional requirements rationale
The Security Objectives for the TOE are covered by the SFRs as follows:
O.AdminAuthorisation is addressed by FIA_UID.2, because this SFR makes sure that only
authorised persons can act as administrators. In addition FMT_SMR.1, FMT_SMF.1,
FMT_MTD.1/Version and FMT_MTD.1/Admin specify the actions allowed for the
administrator.
O.OperatorAuthorisation is also addressed by FIA_UID.2, because this SFR makes sure
that only authorised persons can act as operators. In addition FMT_SMR.1, FMT_SMF.1 and
FMT_MTD.1/Version specify the actions allowed for the operators.
O.DisplayVersion is addressed by FMT_SMF.1, which specifies a requirement to output the
TOE's version number on request of the Operator and Administrator.
O.LogData is addressed by FAU_GEN.1/Audit, which require suitable log data to be
generated.
O.DeletionEphemeralData is addressed by FDP_RIP.1 and FCS_CKM.4, which require
deletion of security relevant data after their use.
O.ProtocolMRTD is realised by several SFRs as follows: The SFRs FCS_CKM.1/*,
FCS_CKM.4, FCS_COP.1/* and FCS_RND.1 from class FCS provide the various
cryptographic functions and protocols used for the MRTD protocols (including the generation
of keys, where applicable). The SFRs FIA_API.1/*, FIA_UAU.4, FIA_UAU.5, FIA_UAU.6/BT
Security Target Bundesdruckerei Document Application Common Criteria Evaluation Page 44/55
from class FIA describe properties of the authentication protocols used between TOE and
MRTDs. FAU_GEN.1/PA requires the TOE to present the enforcement and the result of the
Passive Authentication to the Operator of the EAC-Module.
O.UpdatingSoftware is realized by FDP_IFF.1, FDP_IFC.1, and FCS_COP.1/SW, which
make sure that only authentic software is accepted and moreover, that only newer
software is accepted. FMT_SMF.1, FMT_SMR.1 and FMT_MTD.1/Admin make sure that
only the administrator is able to initiate a firmware update thereby changing the TOE
configuration.
6.4 Dependency rationale for SFRs
The dependency rationale for all SFRs from [PP] is provided in [PP, 6.3.2]. For the additional

7 TOE Summary Specification
This chapter presents a short overview of the security functions implemented by the TOE.
7.1 SF.PROTOCOLS
SF.PROTOCOLS ensures that the following protocols for communication between itself and
eMRTDs are enforced according to [EAC1.11], [EAC2.05], and [ICAO_9303]
(FIA_API.1/BAC, FIA_API.1/PACE, FIA_UAU.4, FIA_UAU.5, and FIA_UAU.6):
• BAC
• Chip Authentication
• PACE
• Passive Authentication
It also ensures that the necessary cryptographic operations for encryption/decryption
(FCS_COP.1/SYM), signature verification (FCS_COP.1/CER), random number generation
(FCS_RND.1), key generation/derivation (FCS_CKM.1/KDF, FCS_CKM.1/DH,
FCS_CKM.1/PACE, FSC_COP.1/SHA, FCS_COP.1/MAC) and key destruction
(FCS_CKM.4) are performed in a secure manner.
The TOE also presents the status for Passive Authentication and Chip Authentication to the
operator (FAU_GEN.1/PA).
Further, all sensitive data including chip data and passwords will be wiped upon deallocation
(FDP_RIP.1).
7.2 SF.MANAGEMENT
SF.MANAGEMENT enforces that the following management functions are accessible to the
administrator of the TOE (FIA_UID.2, FMT_SMR.1, FMT_SMF.1, and FMT_MTD.1/Admin):
• Modification of configuration data of the TOE
• Initiate firmware update
• View the version number of the TOE
• Verify date and time
For firmware update the SF ensures that the update is only performed if the version number
of the firmware to be installed is higher than or equal to the version number of the installed
firmware and authenticity of the firmware to be installed could be verified using signature
verification (FCS_COP.1/SW, FDP_IFC.1, FDP_IFF.1).
It further enforces that operators are allowed to view the version number of the TOE and
verify date and time (FMT_MTD.1/Version).
7.3 SF.AUDIT
The TOE generates audit data (FAU_GEN.1/Audit) which is then stored by the environment.
Table 3 lists the events and further audit relevant information that will be logged. At least the
date and time of the event, the type of the event, and the outcome of the event are part of the
generated audit log.
