The related product is the STARCOS 3.01 PE, Version 1.1 Operating System (OS) on a Smart Card Integrated Circuit. It is the patched version with minor differences to the previously certified product (BSI-DSZ-CC-0313-2006). It is intended to be used as Passport Booklet IC in accordance with [21a] so the TOE consists of the related software in combination with the underlying hardware ('Composite Evaluation'). 'STARCOS 3.01 PE fulfils the requirements specified in [5]. STARCOS 3.01 PE is a fully interoperable ISO 7816 compliant multi-application Smart Card OS, including a cryptographic library enabling the user to apply TDES. The software part of the TOE is implemented on the IC Philips P5CT072, which is certified according to CC EAL5+ [24]. So the TOE consists of the software part and the underlying hardware. This document describes • the Target of Evaluation (TOE) • the security environment of the TOE • the security objectives of the TOE and its environment • and the TOE security functional and assurance requirements. The assurance level for the TOE is CC EAL4+. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 5 of 92 Public/öffentlich 1 Introduction The minimum strength level for the TOE security functions is high (SOF high). 1.3 CC Conformance This TOE claims conformance to: Common Criteria V2.3 (ISO 15408) (see [1], [2], [3]) as follows: - Part 2 extended, - Part 3 conformant, - Package conformant to EAL4 augmented with ADV_IMP.2 and ALC_DVS.2. The TOE meets the specific BSI PP: Protection Profile Machine Readable Travel Document with “ICAO Application” as stated in [21a]). 1.4 Sections Overview Section 1 provides the introductory material for the Security Target. Section 2 provides general purpose and TOE description. Section 3 provides a discussion of the expected environment for the TOE. This section also defines the set of threats that are to be addressed by either the technical countermeasures implemented in the TOE hardware, the TOE software, or through the environmental controls. Section 4 defines the security objectives for both the TOE and the TOE environment. Section 5 contains the functional requirements and assurance requirements derived from the Common Criteria (CC), Part 2 [2] and Part 3 [3], that must be satisfied. Section 6 contains the TOE Summary Specification. Section 7 provides the compliance claims to the PP [21a]. Section 8 provides a rationale to explicitly demonstrate that the information technology security objectives satisfy the policies and threats. Arguments are provided for the coverage of each policy and threat. The section then explains how the set of requirements are complete relative to the objectives, and that each security objective is addressed by one or more component requirements. Arguments are provided for the coverage of each objective. Next section 8 provides a set of arguments that address dependency analysis, strength of function issues, and the internal consistency and mutual supportiveness of the security target requirements Section 9 provides a glossary and acronyms and identifies background material (References). 1.5 Change History Version Date Changes Remarks 1.0 10.07.07 Final Version. stut Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 6 of 92 Public/öffentlich 1 Introduction 1.6 Tables Table 1 Overview on authentication SFR ............................................................................................. 32 Table 2 Assurance Requirements: EAL(4+) ......................................................................................... 44 Table 3 SOF claims for TOE Security Functions.................................................................................. 51 Table 4 References of Assurance Measures.......................................................................................... 55 Table 5 Security Objective Rationale.................................................................................................... 57 Table 6 Coverage of Security Objective for the TOE by SFR.............................................................. 60 Table 7 Coverage of Security Objectives for the IT environment by SFR ........................................... 64 Table 8 Dependencies between the SFR for the TOE......................................................................... 69 Table 9 Dependencies between the SFR for the IT environment ....................................................... 71 Table 10 Functional Requirements to Security Function mapping......................................................... 75 Table 11 Assurance Requirements to Assurance Measures mapping..................................................... 85 1.7 Application Notes of the PP When applicable the application notes of the PP are discussed in notes (1-26).

Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 7 of 92 Public/öffentlich 2 TOE Description 2 TOEDescription Parts of this chapter have been taken from [21a]. 2.1 TOE definition The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine readable travel documents (MRTD’s chip) programmed according to the Logical Data Structure (LDS) [6] and providing the Basic Access Control according to the ICAO document [7]. The TOE comprises of - the circuitry of the MRTD’s chip (the integrated circuit, IC) with hardware for the contactless interface, e.g. antennae, capacitors, - the IC Dedicated Software with the parts IC Dedicated Test Software and IC Dedicated Support Software, - the IC Embedded Software (operating system), - the MRTD application1 and - the associated guidance documentation.

Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 8 of 92 Public/öffentlich 2 TOE Description 2.2 TOE usage and security features for operational use State or organisation issues MRTD to be used by the holder for international travel. The traveller presents a MRTD to the inspection system to prove his or her identity. The MRTD 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 MRTD’s chip according to LDS for contactless machine reading. The authentication of the traveller is based on (i) the possession of a valid MRTD personalized for a holder with the claimed identity as given on the biographical data page and (ii) biometrics using the reference data stored in the MRTD. The issuing State or Organization ensure the authenticity of the data of genuine MRTD’s. The receiving State trust a genuine MRTD of a issuing State or Organization. For this security target the MRTD is viewed as unit of (a) the physical MRTD as travel document in form of paper, plastic and chip. It presents visual readable data including (but not limited to) personal data of the MRTD holder (1) the biographical data on the biographical data page of the passport book, (2) the printed data in the Machine-Readable Zone (MRZ) and (3) the printed portrait. (b) the logical MRTD as data of the MRTD holder stored according to the Logical Data Structure [6] as specified by ICAO on the contactless integrated circuit. It presents contactless readable data including (but not limited to) personal data of the MRTD holder (1) the digital Machine Readable Zone Data (digital MRZ data, DG1), (2) the digitized portraits (DG2), (3) the optional biometric reference data of finger(s) (DG3) or iris image(s) (DG4) or both2 (4) the other data according to LDS (DG5 to DG16) and (5) the Document security object. The issuing State or Organization implements security features of the MRTD to maintain the authenticity and integrity of the MRTD and their data. The MRTD as the passport book and the MRTD’s chip is uniquely identified by the document number. The physical MRTD is protected by physical security measures (e.g. watermark on paper, security printing), logical (e.g. authentication keys of the MRTD’s chip) and organisational security measures (e.g. control of materials, personalization procedures) [8]. These security measures include the binding of the MRTD’s chip to the passport book. The logical MRTD is protected in authenticity and integrity by a digital signature created by the document signer acting for the issuing State or Organization and the security features of the MRTD’s chip. The ICAO defines the baseline security methods Passive Authentication and the optional advanced security methods Basic Access Control to the logical MRTD, Active Authentication of the MRTD’s chip, Extended Access Control to and the Data Encryption of additional biometrics as optional security measure in the ICAO Technical Report [7]. The Passive Authentication Mechanism and the Data Encryption are performed completely and independently on the TOE by the TOE environment. This security target addresses the protection of the logical MRTD (i) in integrity by 2 These additional biometric reference data are optional Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 9 of 92 Public/öffentlich 2 TOE Description write-only-once access control3 and by physical means, and (ii) in confidentiality by the Basic Access Control Mechanism. This security target does not address the Active Authentication and the Extended Access Control as optional security mechanisms. The Basic Access Control is a security feature which shall be mandatory supported by the TOE but may be disabled by the Issuing State or Organization. The inspection system (i) reads the printed data in the MRZ, (ii) authenticates themselves as inspection system by means of keys derived form MRZ data. After successful authentication of the inspection system the MRTD’s chip provides read access to the logical MRTD by means of private communication (secure messaging) with this inspection system [7], Annex E, and [6]. 2.3 TOE life cycle The TOE life cycle is described in terms of the four life cycle phases. Personalisation Data (5) Issuing State Transponder Inlays (4) Personalisa ion t Agent IC Manufacturer Transponder Inlays (2) ROM Mask including data to ensure for secure loading of initialisation (1) Initialisation Data (3) MRTD Manufacturer OS Developer Figure 2 ROM Mask generation and delivery and Initialisation/Personalisation (example) 2.3.1 Phase 1 “Development” 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. 3 The logical MRTD data groups DG1 to DG16 and the TSF data can be written only once and can not be changed after personalization. The TOE does not allow the Re-Personalisation of the MRTD in the Phase 4 Operational Use. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 10 of 92 Public/öffentlich 2 TOE Description The software developer uses the guidance documentation for the integrated circuit and the guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded Software (operating system), the MRTD application and the guidance documentation associated with these TOE components. The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software in the non-volatile non-programmable memories (ROM) is securely delivered to the IC manufacturer((1) of figure 2). The IC Embedded Software in the nonvolatile programmable memories, the MRTD application, the initialisation data ((3) of figure 2). and the guidance documentation is securely delivered to the MRTD manufacturer ((2) of figure 2). 2.3.2 Phase 2 “Manufacturing” In a first step the TOE integrated circuit is produced containing the MRTD’s chip Dedicated Software and the parts of the MRTD’s chip Embedded Software in the nonvolatile non-programmable memories (ROM). The IC manufacturer writes the IC Identification Data onto the chip to control the IC as MRTD material during the IC manufacturing and the delivery process to the MRTD manufacturer. The IC is securely delivered from the IC manufacturer to the MRTD manufacturer ((2) of figure 2).. The MRTD manufacturer (i) add the parts of the IC Embedded Software in the nonvolatile programmable memories (for instance EEPROM) if necessary, (ii) creates the MRTD application, and (iii) equips MRTD’s chip with Per-personalization Data and (iv) packs the IC with hardware for the contactless interface in the passport book. The pre-personalized MRTD together with the IC Identifier is securely delivered from the MRTD manufacturer to the Personalization Agent ((4) of figure 2).. The MRTD manufacturer also provides the relevant parts of the guidance documentation to the Personalization Agent. 2.3.3 Phase 3 “Personalization of the MRTD” The personalization of the MRTD includes (i) the survey of the MRTD holder biographical data, (ii) the enrolment of the MRTD holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), (iii) the printing of the visual readable data onto the physical MRTD and their secure transfer to the personalisation agent ((4) of figure 2)., (iv) the writing of the TOE User Data and TSF Data into the logical MRTD and (v) the writing the TSF Data into the logical MRTD and 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 (DG1), (ii) the digitised portrait (DG2), and (iii) the Document security object. The signing of the Document security object by the Document signer [7] finalizes the personalization of the genuine MRTD for the MRTD holder. The personalized MRTD (together with appropriate guidance for TOE use if necessary) is handed over to the MRTD holder for operational use. – Note 1: This security target distinguishes between the Personalization Agent as entity known to the TOE and the Document Signer as entity in the TOE IT environment signing the Document security object as described in [7]. This approach allows but does not enforce the separation of these roles.. The TOE supports asymmetric and symmetric authentication of the Personalization Agent. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 11 of 92 Public/öffentlich 2 TOE Description 2.3.4 Phase 4 “Operational Use” The TOE is used as MRTD’s chip by the traveller 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 used according to the security policy of the Issuing State but they can never be modified. – Note 2: The TOE does not allow the Re-Personalisation of the MRTD in the Phase 4 Operational Use. – Note 3: The point of TOE delivery according to CC in this ST is after phase 2. The secure transfer of the TOE between the manufacturer and the personalisation site has to be realised. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 12 of 92 Public/öffentlich 3 Security Problem Definition 3 SecurityProblemDefinition This chapter has been taken from [21a] without modification. 3.1 Introduction 3.1.1 Assets The assets to be protected by the TOE include the User Data on the MRTD’s chip. 3.1.1.1 Logical MRTD Data The logical MRTD data consists of the data groups DG1 to DG16 and the Document security object according to LDS [6]. These data are user data of the TOE. The data groups DG1 to DG14 and DG 16 contain personal data of the MRTD holder. The Active Authentication Public Key Info in DG 15 is used by the inspection system for Active Authentication of the chip. The Document security object is used by the inspection system for Passive Authentication of the logical MRTD. An additional asset is the following more general one. 3.1.1.2 Authenticity of the MRTD’s chip The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the MRTD’s holder is used by the traveller to authenticate himself as possessing a genuine MRTD. 3.1.2 Subjects This security target considers the following subjects: 3.1.2.1 Manufacturer The generic term for the IC Manufacturer producing the integrated circuit and the MRTD Manufacturer completing the IC to the MRTD’s chip. The Manufacturer is the default user of the TOE during the Phase 2 Manufacturing. The TOE does not distinguish between the users IC Manufacturer and MRTD Manufacturer using this role Manufacturer. 3.1.2.2 MRTD Holder The rightful holder of the MRTD for whom the issuing State or Organization personalised the MRTD. 3.1.2.3 Traveller Person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder. 3.1.2.4 Personalization Agent The agent is acting on the behalf of the issuing State or Organisation to personalize the MRTD for the holder by some or all of the following activities (i) establishing the identity the holder for the biographic data in the MRTD, (ii) enrolling the biometric Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 13 of 92 Public/öffentlich 3 Security Problem Definition reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s) (iii) writing these data on the physical and logical MRTD for the holder as defined for global, international and national interoperability and (iv) signing the Document Security Object defined in [6]. 3.1.2.5 Inspection system A technical system used by the border control officer of the receiving State (i) examining an MRTD presented by the traveller and verifying its authenticity and (ii) verifying the traveller as MRTD holder. The Primary Inspection System (PIS) (i) contains a terminal for the contactless communication with the MRTD’s chip and (ii) does not implement the terminals part of the Basic Access Control Mechanism. The Primary Inspection System can read the logical MRTD only if the Basic Access Control is disabled. The Basic Inspection System (BIS) (i) contains a terminal for the contactless communication with the MRTD’s chip, (ii) implements the terminals part of the Basic Access Control Mechanism and (iii) gets the authorization to read the logical MRTD under the Basic Access Control by optical reading the printed data in the MRZ or other parts of the passport book providing this information. The Extended Inspection System (EIS) in addition to the Basic Inspection System (i) implements the Active Authentication Mechanism, (ii) supports the terminals part of the Extended Access Control Authentication Mechanism and (iii) is authorized by the issuing State or Organization to read the optional biometric reference data. – Note: 4: This security target does not distinguish between the BIS and EIS because the Active Authentication and the Extended Access Control is outside the scope. 3.1.2.6 Terminal A terminal is any technical system communicating with the TOE through the contactless interface. 3.1.2.7 Attacker A threat agent trying (i) to identify and to trace the movement the MRTD’s chip remotely (i.e. without knowing or reading the printed MRZ data), (ii) to read or to manipulate the logical MRTD without authorization, or (iii) to forge a genuine MRTD. – 3.2 Assumptions The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used. 3.2.1 A.Pers_Agent Personalization of the MRTD’s chip The Personalization Agent ensures the correctness of (i) the logical MRTD with respect to the MRTD holder, (ii) the Document Basic Access Keys, (iii) the Active Authentication Public Key Info (DG15) if stored on the MRTD’s chip, and (iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip). The Personalization Agent signs the Document Security Object. The Personalization Agent bears the Personalization Agent Authentication to authenticate himself to the TOE by symmetric cryptographic mechanisms. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 14 of 92 Public/öffentlich 3 Security Problem Definition 3.2.2 A.Insp_Sys Inspection Systems for global interoperability The Inspection System is used by the border control officer of the receiving State (i) examining an MRTD presented by the traveller and verifying its authenticity and (ii) verifying the traveller as MRTD holder. The Primary Inspection System for global interoperability contains the Country Signing Public Key and the Document Signer Public Key of each issuing State or Organization [7]. The Primary Inspection System performs the Passive Authentication to verify the logical MRTD if the logical MRTD is not protected by Basic Access Control. The Basic Inspection System in addition to the Primary Inspection System implements the terminal part of the Basic Access Control and reads the logical MRTD being under Basic access Control. – Note 5: The TOE allows the Personalization agent to disable the Basic Access Control for use with Primary Inspection Systems. 3.3 Threats This section describes the threats to be averted by the TOE independently or in collaboration with its IT environment. These threats result from the TOE method of use in the operational environment and the assets stored in or protected by the TOE. The TOE in collaboration with its IT environment shall avert the threats as specified below. 3.3.1 T.Chip_ID Identification of MRTD’s chip An attacker trying to trace the movement of the MRTD by identifying remotely the MRTD’s chip by establishing or listening a communication through the contactless communication interface. The attacker can not read and does not know in advance the MRZ data printed on the MRTD data page. 3.3.2 T.Skimming Skimming the logical MRTD An attacker imitates the inspection system to read the logical MRTD or parts of it via the contactless communication channel of the TOE. The attacker can not read and does not know in advance the MRZ data printed on the MRTD data page. 3.3.3 T.Eavesdropping Eavesdropping to the communication between TOE and inspection system An attacker is listening to the communication between the MRTD’s chip and an inspection system to gain the logical MRTD or parts of it. The inspection system uses the MRZ data printed on the MRTD data page but the attacker does not know this data in advance. Note in case of T.Skimming the attacker is establishing a communication with the MRTD’s chip not knowing the MRZ data printed on the MRTD data page and without a help of the inspection system which knows these data. In case of T.Eavesdropping the attacker uses the communication of the inspection system. 3.3.4 T.Forgery Forgery of data on MRTD’s chip An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to impose on an inspection system by means of the changed MRTD holders identity or biometric reference data. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 15 of 92 Public/öffentlich 3 Security Problem Definition 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 an other 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 MRTD’s to create a new forged MRTD, e.g. the attacker write the digitized portrait and optional biometric reference data of finger read from the logical MRTD of a traveller into an other MTRD’s chip leaving their digital MZR unchanged to claim the identity of the holder this MRTD. The attacker may also copy the complete unchanged logical MRTD in an other contactless chip. The TOE shall avert the threat as specified below. 3.3.5 T.Abuse-Func Abuse of Functionality An attacker may use functions of the TOE which shall not be used in TOE operational phase in order (i) to manipulate User Data, (ii) to manipulate (explore, bypass, deactivate or change) security features or functions of the TOE or (iii) to disclose or to manipulate TSF Data. This threat addresses misuse of the functions for the initialization and the personalization in the operational state after delivery to MRTD holder. 3.3.6 T.Information_Leakage Information Leakage from MRTD’s chip An attacker may exploit information which is leaked from the TOE during its usage in order to disclose confidential TSF data. The information leakage may be inherent in the normal operation or caused by the attacker. Leakage may occur through emanations, variations in power consumption, I/O characteristics, clock frequency, or by changes in processing time requirements. This leakage may be interpreted as a covert channel transmission but is more closely related to measurement of operating parameters, which may be derived either from measurements of the contactless interface (emanation) or direct measurements (by contact to the chip still available even for a contactless chip) and can then be related to the specific operation being performed. Examples are the Differential Electromagnetic Analysis (DEMA) and the Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis). 3.3.7 T.Phys-Tamper Physical Tampering An attacker may perform physical probing of the MRTD’s chip in order (i) to disclose TSF Data, or (ii) to disclose/reconstruct the MRTD’s chip Embedded Software. An attacker may physically modify the MRTD’s chip in order to (i) modify security features or functions of the MRTD’s chip, (ii) modify security functions of the MRTD’s chip Embedded Software, (iii) to modify User Data or (iv) to modify TSF data. The physical tampering may be focused directly on the discloser or manipulation of Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 16 of 92 Public/öffentlich 3 Security Problem Definition TOE User Data (e.g. the biometric reference data for the inspection system) or TSF Data (e.g. authentication key of the MRTD’s chip) or indirectly by preparation of the TOE to following attack methods by modification of security features (e.g. to enable information leakage through power analysis). Physical tampering requires direct interaction with the MRTD’s chip internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of User Data and TSF Data may also be a prerequisite. The modification may result in the deactivation of a security function. Changes of circuitry or data can be permanent or temporary. 3.3.8 T.Malfunction Malfunction due to Environmental Stress An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functions of the TOE or (ii) circumvent or deactivate or modify security functions of the MRTD’s chip Embedded Software. This may be achieved e.g. by operating the MRTD’s chip outside the normal operating conditions, exploiting errors in the MRTD’s chip Embedded Software or misuse of administration function. To exploit this an attacker needs information about the functional operation. 3.4 Organisational Security Policies The TOE shall comply to the following organisation security policies (OSP) as security rules, procedures, practices, or guidelines imposed by an organisation upon its operations (see CC part 1 [1], sec. 3.2). 3.4.1 P.Manufact Manufacturing of the MRTD’s chip The IC Manufacturer and MRTD Manufacturer ensure the quality and the security of the manufacturing process and control the MRTD’s material in the Phase 2 Manufacturing. The Initialization Data are written by the IC Manufacturer to identify the IC uniquely. The MRTD Manufacturer writes the Pre-personalization Data which contains at least the Personalization Agent Key. 3.4.2 P.Personalization Personalization of the MRTD by issuing State or Organization only The issuing State or Organization guarantees the correctness of the biographical data, the printed portrait and the digitised portrait, the biometric reference data and other data of the logical MRTD with respect to the MRTD holder. The personalization of the MRTD for the holder is performed by authorized agents of the issuing State or Organization only. 3.4.3 P.Personal_Data Personal data protection policy The biographical data and their summary printed in the MRZ and stored on the MRTD’s chip (DG1), the printed portrait and the digitised portrait (DG2), the biometric reference data of finger(s) (DG3), the biometric reference data of iris image(s) (DG4) and data Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 17 of 92 Public/öffentlich 3 Security Problem Definition according to LDS (DG5 to DG14, DG16) stored on the MRTD’s chip are personal data of the MRTD holder. These data groups are intended to be used only with agreement of the MRTD holder by inspection systems to which the MRTD is presented. The MRTD’s chip shall provide the possibility for the Basic Access Control to allow read access to these data only for terminals successfully authenticated based on knowledge of the Document Basic Access Keys as defined in [7]. The issuing State or Organization decides (i) to enable the Basic Access Control for the protection of the MRTD holder personal data or (ii) to disable the Basic Access Control to allow Primary Inspection Systems of the receiving States and all other terminals to read the logical MRTD. – Note 6: The organisational security policy P.Personal_Data is drawn from the ICAO Technical Report [7]. Note that the Document Basic Access Key is defined by the TOE environment and loaded to the TOE by the Personalization Agent. 3.5 Security Objectives This chapter describes the security objectives for the TOE and the security objectives for the TOE environment. The security objectives for the TOE environment are separated into security objectives for the development and production environment and security objectives for the operational environment. 3.5.1 Security Objectives for the TOE This section describes the security objectives for the TOE addressing the aspects of identified threats to be countered by the TOE and organisational security policies to be met by the TOE. 3.5.1.1 OT.AC_Pers Access Control for Personalization of logical MRTD The TOE must ensure that the logical MRTD data groups DG1 to DG16, the Document security object according to LDS [6] and the TSF data can be written by authorized Personalization Agents. The logical MRTD data groups DG1 to DG16 and the TSF data can be written only once and can not be changed after personalization. The Document security object can be updated by authorized Personalization Agents if data in the data groups DG 3 to DG16 are added. Only the Personalization Agent shall be allowed to enable or to disable the TSF Basic Access Control. – Note 7: The TOE does not allow the Re-Personalisation of the MRTD in the Phase 4 Operational Use. 3.5.1.2 OT.Data_Int Integrity of personal data The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. If the TOE is configured for the use with Basic Inspection Terminals only the TOE must ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data. 3.5.1.3 OT.Data_Conf Confidentiality of personal data If the TOE is configured for the use with Basic Inspection Systems the TOE must ensure the confidentiality of the logical MRTD data groups DG1 to DG16 by granting read access to terminals successfully authenticated by (i) as Personalization Agent or as (ii) Basic Inspection System. The Basic Inspection System shall authenticate themselves by means of the Basic Access Control based on knowledge of the Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 18 of 92 Public/öffentlich 3 Security Problem Definition Document Basic Access Key. The TOE must ensure the confidentiality of the logical MRTD data during their transmission to the Basic Inspection System. If the TOE is configured for the use with Primary Inspection Systems no protection in confidentiality of the logical MRTD is required. – Note 8: The TOE provides read access to these data for terminals successfully authenticated by means of the Basic Access Control based on knowledge of the Document Basic Access Keys The TOE to ensures the strength of the security function Basic Access Control Authentication independent on the quality of the Document Basic Access Keys which is defined by the TOE environment and loaded into the TOE by the Personalization Agent. 3.5.1.4 OT.Identification Identification and Authentication of the TOE The TOE must provide means to store IC Identification Data in its non-volatile memory. The IC Identification Data must provide an unique identification of the IC during Phase 2 “Manufacturing” and Phase 3 “Personalization of the MRTD”. If the TOE is configured for use with Basic Inspection Terminals only in Phase 4 “Operational Use” the TOE shall identify themselves only to a successful authenticated Basic Inspection System or Personalization Agent. – Note 9:. If the TOE is configured to allow a Basic Inspection System only to read these data the output of any other IC (e.g. integrated circuit serial number ICCSN) or a MRTD identifier through the contactless interface before successful authentication as Basic Inspection System or as Personalization Agent is forbidden. 3.5.1.5 OT.Prot_Abuse-Func Protection against Abuse of Functionality The TOE must prevent that functions of the TOE which may not be used after TOE Delivery can be abused in order (i) to disclose critical User Data, (ii) to manipulate critical User Data of the Smartcard Embedded Software, (iii) to manipulate Soft-coded Smartcard Embedded Software or (iv) bypass, deactivate, change or explore security features or functions of the TOE. Details of the relevant attack scenarios depend, for instance, on the capabilities of the Test Features provided by the IC Dedicated Test Software which are not specified here. The following TOE security objectives address the protection provided by the MRTD’s chip independent on the TOE environment. 3.5.1.6 OT.Prot_Inf_Leak Protection against Information Leakage The TOE must provide protection against disclosure of confidential TSF data stored and/or processed in the MRTD’s chip - by measurement and analysis of the shape and amplitude of signals or the time between events found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines and - by forcing a malfunction of the TOE and/or - by a physical manipulation of the TOE. – Note 10: This objective pertains to measurements with subsequent complex signal processing due to normal operation of the TOE or operations enforced by an attacker.. 3.5.1.7 OT.Prot_Phys-Tamper Protection against Physical Tampering The TOE must provide protection the confidentiality and integrity of the User Data, the TSF Data, and the MRTD’s chip Embedded Software. This includes protection against Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 19 of 92 Public/öffentlich 3 Security Problem Definition attacks with high attack potential by means of - measuring through galvanic contacts which is direct physical probing on the chips surface except on pads being bonded (using standard tools for measuring voltage and current) or - measuring not using galvanic contacts but other types of physical interaction between charges (using tools used in solid-state physics research and IC failure analysis) - manipulation of the hardware and its security features, as well as - controlled manipulation of memory contents (User Data, TSF Data). with a prior - reverse-engineering to understand the design and its properties and functions. – Note 11: The TOE is designed and fabricated so that it requires a high combination of complex equipment, knowledge, skill, and time to be able to derive detailed design information or other information which could be used to compromise security through such a physical attack. 3.5.1.8 OT.Prot_Malfunction Protection against Malfunctions The TOE must ensure its correct operation. The TOE must prevent its operation outside the normal operating conditions where reliability and secure operation has not been proven or tested. This is to prevent errors. The environmental conditions may include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency, or temperature. – 3.5.2 Security Objectives for the Development and Manufacturing Environment 3.5.2.1 OD.Assurance Assurance Security Measures in Development and Manufacturing Environment The developer and manufacturer ensure that the TOE is designed and fabricated so that it requires a combination of complex equipment, knowledge, skill, and time to be able to derive detailed design information or other information which could be used to compromise security through attack. This includes the use of the Initialization Data for unique identification of the TOE and the pre-personalization of the TOE including the writing of the Personalization Agent Authentication key(s). The developer provides necessary evaluation evidence that the TOE fulfils its security objectives and is resistant against obvious penetration attacks with low attack potential and against direct attacks with high attack potential against security function that uses probabilistic or permutational mechanisms. 3.5.2.2 OD.Material Control over MRTD Material The IC Manufacturer, the MRTD Manufacturer and the Personalization Agent must control all materials, equipment and information to produce, to initialise, to pre- personalize genuine MRTD materials and to personalize authentic MRTD in order to prevent counterfeit of MRTD using MRTD materials. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 20 of 92 Public/öffentlich 3 Security Problem Definition 3.5.3 Security Objectives for the Operational Environment 3.5.3.1 Issuing State or Organization The Issuing State or Organization will implement the following security objectives of the TOE environment. 3.5.3.1.1 OE.Personalization Personalization of logical MRTD The issuing State or Organization must ensure that the Personalization Agents acting on the behalf of the issuing State or Organisation (i) establish the correct identity the holder and create biographic data for the MRTD, (ii) enrol the biometric reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s) and (iii) personalize the MRTD for the holder together with the defined physical and logical security measures (including the digital signature in the Document Security Object). The Personalization Agents enable or disable the Basic Access Control function of the TOE according to the decision of the issuing State or Organization. If the Basic Access Control function is enabled the Personalization Agents generate the Document Basic Access Keys and store them in the MRTD’s chip 3.5.3.1.2 OE.Pass_Auth_Sign Authentication of logical MRTD by Signature The Issuing State or Organization must (i) generate a cryptographic secure Country Signing Key Pair, (ii) ensure the secrecy of the Country Signing Private Key and sign Document Signer Certificates in a secure operational environment, and (iii) distribute the Certificate of the Country Signing Public Key to receiving States and organizations maintaining its authenticity and integrity. The Issuing State or organization must (i) generate a cryptographic secure Document Signing Key Pair and ensure the secrecy of the Document Signer Private Keys, (ii) sign Document Security Objects of genuine MRTD in a secure operational environment only and (iii) distribute the Certificate of the Document Signing Public Key to receiving States and organizations. The digital signature in the Document Security Object include all data in the data groups DG1 to DG16 if stored in the LDS according to [6]. 3.5.3.2 Receiving State or organization The Receiving State or Organization will implement the following security objectives of the TOE environment. 3.5.3.2.1 OE.Exam_MRTD Examination of the MRTD passport book The inspection system of the Receiving State must examine the MRTD presented by the traveller to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical MRTD. 3.5.3.2.2 OE.Passive_Auth_Verif Verification by Passive Authentication The border control officer of the Receiving State uses the inspection system to verify the traveller as MRTD holder. The inspection systems must have successfully verified the signature of Document Security Objects and the integrity data elements of the logical MRTD before they are used. The receiving States and organizations must manage the Country Signing Public Key and the Document Signing Public Key maintaining their authenticity and availability in all inspection systems. 3.5.3.2.3 OE.Prot_Logical_MRTD Protection of data of the logical MRTD Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 21 of 92 Public/öffentlich 3 Security Problem Definition The inspection system of the receiving State ensures the confidentiality and integrity of the data read from the logical MRTD. The receiving State examining the logical MRTD being under Basic Access Control will use inspection systems which implement the terminal part of the Basic Access Control and use the secure messaging with fresh generated keys for the protection of the transmitted data (i.e. Basic Inspection Systems). The receiving State examining the logical MRTD with Primary Inspection Systems will prevent eavesdropping to the communication between TOE and inspection system. – Note 12: The Primary Inspection System may prevent unauthorized listening to or manipulation of the communication with the MRTD’s chip e.g. by a Faraday cage. 3.5.3.3 MRTD Holder 3.5.3.3.1 OE.Secure_Handling Secure handling of the MRTD by MRTD holder The holder of a MRTD configured for use with Primary Inspection Systems (i.e. MTRD with disabled Basic Access Control) will prevent unauthorized communication of the MRTD’s chip with terminals through the contactless interface. – Note 13: The MRTD holder may prevent unauthorized communication of the MRTD’s chip with terminals e.g. by carrying the MRTD in a metal box working as a Faraday cage. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 22 of 92 Public/öffentlich 4 Extended Components Definition 4 ExtendedComponentsDefinition This security target uses components defined as extensions to CC part 2 [2]. Some of these components are defined in [20], other components are defined in [21a]. This chapter has been taken from [21a] without modification. 4.1 Definition of the Family FAU_SAS To define the security functional requirements of the TOE an additional family (FAU_SAS) of the Class FAU (Security Audit) is defined in [21a].. 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. 4.1.1 FAU_SAS Audit data storage Family behaviour This family defines functional requirements for the storage of audit data. Component levelling FAU_SAS.1 Requires the TOE to provide the possibility to store audit data. Management: FAU_SAS.1 There are no management activities foreseen. Audit: FAU_SAS.1 There are no actions defined to be auditable. 4.1.2 FAU_SAS.1 Audit storage Hierarchical to: No other components. FAU_SAS.1.1 The TSF shall provide [assignment: authorised users] with the capability to store [assignment: list of audit information] in the audit records. Dependencies: No dependencies. 4.2 Definition of the Family FCS_RND To define the IT security functional requirements of the TOE an additional family (FCS_RND) of the Class FCS (cryptographic support) is defined in [21a].. This family describes the functional requirements for random number generation used for cryptographic purposes. The component FCS_RND is not limited to generation of cryptographic keys as the component FCS_CKM.1 is. The similar component FIA_SOS.2 is intended for non-cryptographic use. The family “Generation of random numbers (FCS_RND)” is specified as follows. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 23 of 92 Public/öffentlich 4 Extended Components Definition 4.2.1 FCS_RND Generation of random numbers Family behaviour This family defines quality requirements for the generation of random numbers which are intended to be used for cryptographic purposes. Component levelling: FCS_RND.1 Generation of random numbers requires that random numbers meet a defined quality metric. Management: FCS_RND.1 There are no management activities foreseen. Audit: FCS_RND.1 There are no actions defined to be auditable. FCS_RND.1 Quality metric for random numbers Hierarchical to: No other components. FCS_RND.1.1 The TSF shall provide a mechanism to generate random numbers that meet [assignment: a defined quality metric]. Dependencies: No dependencies. 4.3 Definition of the Family FIA_API To describe the IT security functional requirements of the TOE an additional family (FIA_API) of the Class FIA (Identification and authentication) is defined in [21a].. This family describes the functional requirements for the proof of the claimed identity for the authentication verification by an external entity where the other families of the class FIA address the verification of the identity of an external entity. – Note 14: This security target uses this explicit stated SFR for the personalization terminal in the IT environment only. Therefore the word “TSF” is substituted by the word “Personalization terminal”. 4.3.1 FIA_API Authentication Prove of Identity Family behaviour This family defines functions provided by the TOE to prove their identity and to be verified by an external entity in the TOE IT environment. Component levelling: FIA_API.1 Authentication Prove of Identity. Management: FIA_API.1 The following actions could be considered for the management functions in FMT: Management of authentication information used to prove the claimed identity. Audit: FCS_RND.1 There are no actions defined to be auditable. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 24 of 92 Public/öffentlich 4 Extended Components Definition 4.3.1.1 FIA_API.1 Authentication Proof of Identity Hierarchical to: No other components. FIA_API.1.1 The TSF shall provide a [assignment: authentication mechanism] to prove the identity of the [assignment: authorized user or rule]. Dependencies: No dependencies. 4.4 Definition of the Family FMT_LIM The family FMT_LIM describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The family “Limited capabilities and availability (FMT_LIM)” is specified as follows. 4.4.1 FMT_LIM Limited capabilities and availability Family behaviour This family defines requirements that limits the capabilities and availability of functions in a combined manner. Note that FDP_ACF restricts the access to functions whereas the Limited capability of this family requires the functions themselves to be designed in a specific manner. Component levelling: FMT_LIM.1 Limited capabilities requires that the TSF is built to provide only the capabilities (perform action, gather information) necessary for its genuine purpose. FMT_LIM.2 Limited availability requires that the TSF restrict the use of functions (refer to Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or by disabling functions in a specific phase of the TOE’s life-cycle. Management: FMT_LIM.1, FMT_LIM.2 There are no management activities foreseen. Audit: FMT_LIM.1, FMT_LIM.2 There are no actions defined to be auditable. To define the IT security functional requirements of the TOE an additional family (FMT_LIM) of the Class FMT (Security Management) is defined here. This family describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability.

FMT_LIM.2 Limited availability Hierarchical to: No other components. FMT_LIM.2.1 The TSF shall be designed in a manner that limits their availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced [assignment: Limited capability and availability policy]. Dependencies: FMT_LIM.1 Limited capabilities. 4.5 Definition of the Family FPT_EMSEC The additional family FPT_EMSEC (TOE Emanation) of the Class FPT (Protection of the TSF) is defined in [21a]. to describe the IT security functional requirements of the TOE. The TOE shall prevent attacks against the logical MRTD data and other secret data where the attack is based on external observable physical phenomena of the TOE. Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA), differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for the limitation of intelligible emanations which are not directly addressed by any other component of CC part 2 [2]. The family “TOE Emanation (FPT_EMSEC)” is specified as follows. Family behaviour This family defines requirements to mitigate intelligible emanations. Component levelling: FPT_EMSEC.1 TOE emanation has two constituents: FPT_EMSEC.1.1 Limit of Emissions requires to not emit intelligible emissions enabling access to TSF data or user data. FPT_EMSEC.1.2 Interface Emanation requires not emit interface emanation enabling access to TSF data or user data. Management: FPT_EMSEC.1 There are no management activities foreseen. Audit: FPT_EMSEC.1 There are no actions defined to be auditable.

The CC allows several operations to be performed on functional requirements; refinement, selection, assignment, and iteration are defined in paragraph 2.1.4 of Part 2 of the CC. Each of these operations is used in this security target. 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 and the original text of the component is given by a footnote. Selections filled in by the ST author appear as double underlined text. 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 filled in this ST as underlined text.. 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. 5.1 Security Functional Requirements for the TOE This section on security functional requirements for the TOE is divided into sub-section following the main security functionality. 5.1.1 Class FAU Security Audit The TOE shall meet the requirement “Audit storage (FAU_SAS.1)” as specified below.

The Basic Access Control Mechanism establish strong cryptographic keys for the secure messaging to ensure the confidentiality by Triple-DES and integrity by Retail-MAC of the transmitted data. This approach may be used in a personalization environment where the communication between the MRTD’s chip and the personalization terminal may be listen or manipulated. (2) In a centralized personalization scheme the major issue is high productivity of personalization in a high secure environment. In this case the personalization agent may wish to reduce the protocol to symmetric authentication of the terminal without secure messaging.

Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 56 of 92 Public/öffentlich 8 Rationale 8 Rationale The chapters 8.1 and 8.2 have been taken from [21a] without modification and show that the security objectives cover the TOE security environment and IT security requirements are appropriate to satisfy the security objectives. The tables in sub-sections 8.1, 8.2 and 8.3.1 Rationale for TOE Security Functions provide the mapping of the security objectives and security requirements for the TOE. 8.1 Security Objectives Rationale The following table provides an overview for security objectives coverage. Table 5 Security Objective Rationale The OSP P.Manufact “Manufacturing of the MRTD’s chip” requires the quality and integrity of the manufacturing process and control the MRTD’s material in the Phase 2 Manufacturing including unique identification of the IC by means of the Initialization Data and the writing of the Pre-personalization Data. The security objective for the TOE environment OD.Assurance “Assurance Security Measures in Development and Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 57 of 92 Public/öffentlich 8 Rationale Manufacturing Environment” address these obligations of the IC Manufacturer and MRTD Manufacturer. The OSP P.Personalization “Personalization of the MRTD by issuing State or Organization only” addresses the (i) the enrolment of the logical MRTD by the Personalization Agent as described in the security objective for the TOE environment OE.Personalization “Personalization of logical MRTD”, and (ii) the access control for the user data and TSF data as described by the security objective OT.AC_Pers “Access Control for Personalization of logical MRTD”. Note, the manufacturer equips the TOE with the Personalization Agent Authentication key(s) according to OD.Assurance “Assurance Security Measures in Development and Manufacturing Environment”. The security objective OT.AC_Pers limits the management of TSF data and the enabling and disabling of the TSF Basic Access Control to the Personalization Agent. The OSP P.Personal_Data “Personal data protection policy” requires the TOE (i) to support the protection of the confidentiality of the logical MRTD by means of the Basic Access Control and (ii) enforce the access control for reading as decided by the issuing State or Organization. This policy is implemented by the security objectives OT.Data_Int “Integrity of personal data“ which describes the unconditional protection of the integrity of the stored data and the configurable integrity protection during the transmission. The security objective OT.Data_Conf “Confidentiality of personal data” describes the protection of the confidentiality as configured by the Personalization Agent acting in charge of the issuing State or Organization. The threat T.Chip_ID “Identification of MRTD’s chip” addresses the trace of the MRTD movement by identifying remotely the MRTD’s chip through the contactless communication interface. In case of TOE configuration for use with Basic Inspection Terminals only this threat is countered as described by the security objective OT.Identification by Basic Access Control. If the TOE is configured for use with Primary Inspection Systems this threat shall be adverted by the TOE environment as described by OE.Secure_Handling. The threat T.Skimming “Skimming digital MRZ data or the digital portrait” and T.Eavesdropping “Eavesdropping to the communication between TOE and inspection system” address the reading of the logical MRTD trough the contactless interface or listening the communication between the MRTD’s chip and a terminal. In case of TOE configuration for use with Basic Inspection Terminals only this threat is countered by the security objective OT.Identification through Basic Access Control. If the TOE is configured for use with Primary Inspection Systems the threat T.Skimming shall be adverted by the TOE environment according to OE.Secure_Handling “Secure handling of the MRTD by MRTD holder” and the threat T.Eavesdropping shall be adverted by OE.Prot_Logical_MRTD “Protection of data of the logical MRTD”. 240 The threat T.Forgery “Forgery of data on MRTD’s chip” address the fraudulent alteration of the complete stored logical MRTD or any part of it. The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD“ requires the TOE to limit the write access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity of the stored logical MRTD according the security objective OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against Physical Tampering”. The examination of the presented MRTD passport book according to OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book does not contain an additional Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 58 of 92 Public/öffentlich 8 Rationale contactless chip which may present the complete unchanged logical MRTD. The TOE environment will detect partly forged logical MRTD data by means of digital signature which will be created according to OE.Pass_Auth_Sign “Authentication of logical MRTD by Signature” and verified by the inspection system according to OE.Passive_Auth_Verif “Verification by Passive Authentication”. The threat T.Abuse-Func “Abuse of Functionality” addresses attacks using the MRTD’s chip as production material for the MRTD and misuse of the functions for personalization in the operational state after delivery to MRTD holder to disclose or to manipulate the logical MRTD. The security objectives for the TOE environment OD.Material “Control over MRTD Material” ensures the control of the MRTD material. The security objectives for the TOE environment OD.Assurance “Assurance Security Measures in Development and Manufacturing Environment” and OE.Personalization “Personalization of logical MRTD” ensure that the TOE security functions for the initialization and the personalization are disabled and the security functions for the operational state after delivery to MRTD holder are enabled according to the intended use of the TOE. The threats T.Information_Leakage “Information Leakage from MRTD’s chip”, T.Phys-Tamper “Physical Tampering” and T.Malfunction “Malfunction due to Environmental Stress” are typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against these threats are addressed by the directly related security objectives OT.Prot_Inf_Leak “Protection against Information Leakage”, OT.Prot_Phys-Tamper “Protection against Physical Tampering” and OT.Prot_Malfunction “Protection against Malfunctions”. The assumption A.Pers_Agent “Personalization of the MRTD’s chip” is covered by the security objective for the TOE environment OE.Personalization “Personalization of logical MRTD” including the enrolment, the protection with digital signature and the storage of the MRTD holder personal data and the enabling of security features of the TOE according to the decision of the Issuing State or Organization concerning the Basic Access Control. The examination of the MRTD passport book addressed by the assumption A.Insp_Sys “Inspection Systems for global interoperability” is covered by the security objectives for the TOE environment OE.Exam_MRTD “Examination of the MRTD passport book”. If the Issuing State of Organization decides to protect confidentiality of the logical MRTD than the the security objectives for the TOE environment OE.Prot_Logical_MRTD “Protection of data of the logical MRTD” will require the Basic Inspection System to implement the Basic Access Control and to protect the logical MRTD data during the transmission and the internal handling. If the Issuing State of Organization decides to configure the TOE for use with Primary Inspection Systems than no protection of the logical MRTD data is required by the inspection system. 8.2 Security Requirements Rationale 8.2.1 Security Functional Requirements Rationale Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 59 of 92 Public/öffentlich 8 Rationale The following table provides an overview for security functional requirements coverage. Table 6 Coverage of Security Objective for the TOE by SFR The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD” address the access control of the writing the logical MRTD and the management of the TSF for Basic access Control. The write access to the logical MRTD data are defined by the SFR FDP_ACC.1/PRIM, FDP_ACC.1/BASIC, FDP_ACF.1/PRIM and FDP_ACF.1/BASIC in the same way: only the successfully authenticated Personalization Agent is allowed to write the data of the groups DG1 to DG16 of the logical MRTD only once. Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 60 of 92 Public/öffentlich 8 Rationale The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4/MRTD and FIA_UAU.5/MRTD. In case the Basic Access Control Authentication Mechanism was used the SFR FIA_UAU.6/MRTD describes the re-authentication and FDP_UCT.1 and FDP_UIT.1 the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1/BAC_MRTD, FCS_COP.1/SHA_MRD, FCS_RND.1 (for key generation), and FCS_COP.1/TDES_MRTD and FCS_COP:1/MAC_MRTD for the ENC_MAC_Mode. The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization) because the Personalization Agent handles the configuration of the TSF Basic Access Control according to the SFR FMT_MOF.1 and the Document Basic Access Keys according to the SFR FMT_MTD.1/KEY_WRITE as authentication reference data if Basic Access Control is enabled. The SFR FMT_MTD.1/KEY_READ preventing read access to the secret key of the Personalization Agent Keys and ensure together with the SFR FPT_EMSEC.1, FPT_FLS.1 and FPT_PHP.3 the confidentially of these keys. The security objective OT.Data_Int “Integrity of personal data” requires the TOE to protect the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The write access to the logical MRTD data is defined by the SFR FDP_ACC.1/PRIM, FDP_ACC.1/BASIC, FDP_ACF.1/PRIM and FDP_ACF.1/BASIC in the same way: only the Personalization Agent is allowed to write data of the groups DG1 to DG16 of the logical MRTD (FDP_ACF.1.2, rule 1) and terminals are not allowed to modify any of the data groups DG1 to DG16 of the logical MRTD (cf. FDP_ACF.1.4). The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization) If the TOE is configured for the use with Basic Inspection Terminals only by means of FMT_MOF.1 the security objective OT.Data_Int “Integrity of personal data” requires the TOE to ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data. The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4/MRTD, FIA_UAU.5/MRTD and FIA_UAU.6/MRTD. The SFR FIA_UAU.6/MRTD, FDP_UCT.1 and FDP_UIT.1 requires the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1/BAC_MRTD, FCS_COP.1/SHA_MRD, FCS_RND.1 (for key generation), and FCS_COP.1/TDES_MRTD and FCS_COP.1/MAC_MRTD for the ENC_MAC_Mode. The SFR FMT_MTD.1/KEY requires the Personalization Agent to establish the Document Basic Access Control Keys and the Personalization Agent handles the configuration of the TSF Basic Access Control according to the SFR FMT_MOF.1. The security objective OT.Data_Conf “Confidentiality of personal data” requires the TOE to ensure the confidentiality of the logical MRTD data groups DG1 to DG16 if the TOE is configured for the use with Basic Inspection Systems by means of FMT_MOF.1. The SFR FIA_UID.1 and FIA_UAU.1 allow only those actions before identification respective authentication which do not violate OT.Data_Conf. The read access to the logical MRTD data is defined by the FDP_ACC.1/BASIC and FDP_ACF.1.2/BASIC: only the successful authenticated Personalization Agent and the successful Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 61 of 92 Public/öffentlich 8 Rationale authenticated Basic Inspection System are allowed to read the data of the logical MRTD. The SFR FMT_SMR.1 lists the roles (including Personalization Agent and Basic Inspection System) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization for the key management for the Document Basic Access Control Keys). The SFR FIA_UAU.4/MRTD prevents reuse of authentication data to strengthen the authentication of the user. The FIA_UAU.5 enforce the TOE to accept the authentication attempt as Basic Inspection System only by means of the Basic Access Control Authentication Mechanism with the Document Basic Access Keys. Moreover, the SFR FIA_UAU.6 request secure messaging after successful authentication of the terminal with Basic Access Control Authentication Mechanism which includes the protection of the transmitted data in ENC_MAC_Mode by means of the cryptographic functions according to FCS_COP.1/TDES_MRTD and FCS_COP.1/MAC_MRTD (cf. the SFR FDP_UCT.1 and FDP_UIT.1). (for key generation), and FCS_COP.1/TDES_MRTD and FCS_COP.1/MAC_MRTD for the ENC_MAC_Mode. The SFR FCS_CKM.1/BAC_MRTD, FCS_CKM.4, FCS_COP.1/SHA_MRTD and FCS_RND.1 establish the key management for the secure messaging keys. The SFR FMT_MTD.1/KEY_WRITE addresses the key management and FMT_MTD.1/KEY_READ prevents reading of the Document Basic Access Keys. Note, neither the security objective OT.Data_Conf nor the SFR FIA_UAU.5 requires the Personalization Agent to use the Basic Access Control Authentication Mechanism or secure messaging. If the TOE is configured for the use with Primary Inspection Systems no protection in confidentiality of the logical MRTD is needed to ensure. The security objective OT.Identification “Identification and Authentication of the TOE” address the storage of the IC Identification Data uniquely identifying the MRTD’s chip in its non-volatile memory. This will be ensure by TSF according to SFR FAU_SAS.1. Furthermore, if the TOE is configured for use with Basic Inspection Terminals the TOE shall identify themselves only to a successful authenticated Basic Inspection System in Phase 4 “Operational Use”. The SFR FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization Data and Pre-personalization Data. The SFR FMT_MTD.1/INI_DIS allow the Personalization Agent to disable Initialization Data if their use in the phase 4 “Operational Use” violate the security objective OT.Identification. The SFR FIA_UID.1 and FIA_UAU.1 do not allow reading of any data uniquely identifying the MRTD’s chip before successful authentication of the Basic Inspection Terminal and will stop communication after unsuccessful authentication attempt (cf. Application note 28). The FMT_MTD.1/INI_ENA restricts the ability to write the Initialization Data and Pre- personalization Datato the Manufacturer. The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is ensured by (i) the SFR FMT_LIM.1 and FMT_LIM.2 which prevent misuse of test functionality of the TOE or other which may not be used after TOE Delivery, (ii) the SFR FPT_RVM.1 which prevents by monitoring the bypass and deactivation of security features or functions of the TOE, and (iii) the SFR FPT_SEP.1 which prevents change or explore security features or functions of the TOE by means of separation the other TOE functions.

The security objective OT.Prot_Phys-Tamper “Protection against Physical Tampering” is covered by the SFR FPT_PHP.3. The security objective OT.Prot_Malfunction “Protection against Malfunctions” is covered by (i) the SFR FPT_TST.1 which requires self tests to demonstare the correct operation and tests of authorized users to verify the integrity of TSF data and TSF code, (ii) the SFR FPT_FLS.1 which requires a secure state in case of detected failure or operating conditions possibly causing a malfunction, and (iii) the SFR FPT_SEP.1 limiting the effects of malfunctions due to TSF domain separation. The following table provides an overview how security functional requirements for the IT environment cover security objectives for the TOE environment. The protection profile describes only those SFR of the IT environment directly related to the SFR for the TOE. It does not state any SFR for the IT environment supporting the security objectives OD.Assurance and OD.Material. The OE.Exam_MRTD uses only security function of the IT environment, i.e. the passive authentication. The security objective OE.Prot_Logical_MRTD is directed to Basic Inspection Systems only which cooperate Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 63 of 92 Public/öffentlich 8 Rationale with the TOE in protection of the logical MRTD. Table 7 Coverage of Security Objectives for the IT environment by SFR The document signer provides the security function Passive Authentication according to FDP_DAU.1(DS to support the inspection system to verify the logical MRTD. The security objective OE.Prot_Logical_MRTD “Protection of data of the logical address the protection of handling. The SFR FIA_UAU.4/BT and FIA_UAU.6/BT address the terminal part of the Basic Access Control Authentication Mechanism and FDP_UCT.1/BT and FDP_UIT.1/BT the secure messaging established by this mechanism. The SFR FCS_CKM.1/BAC_BT, FCS_COP.1/SHA_BT, FCS_COP.1/ENC_BT, FCS_COP.1/MAC_BT and FCS_RND.1/BT are necessary to implement this mechanism. The BIS shall destroy the Document Access Control Key and the secure messaging key after inspection of the MRTD because they are not needed any more. The OE.Personalization “Personalization of logical MRTD” requires the MRTD“ personalization terminal to authenticate themselves to the MRTD’s chip to get the write authorization. This implies to implement the Basic Access Control Authentication Mechanism with the Personalization Agent Authentication Keys or support the symmetric authentication protocol according to the SFR FIA_API.1/SYM_PT.

EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 is applicable in those circumstances where developers or users require a moderate to high level of independently assured security in conventional commodity TOEs and are prepared to incur additional security specific engineering costs. The selection of component ADV_IMP.2 provides a higher assurance for the implementation of the MRTD’s chip especially for the absence of unintended functionality. The selection of the component ALC_DVS.2 provides a higher assurance of the security of the MRTD’s development and manufacturing especially for the secure handling of the MRTD’s material. The minimal strength of function “high” was selected to ensure resistance against direct attacks on functions based on probabilistic or permutational mechanisms. The components ADV_IMP.2 and ALC_DVS.2 augmented to EAL4 has dependencies to other security requirements fulfilled within EAL4 Dependencies ADV_IMP.2 ADV_LLD.1 Descriptive low-level design ALC_TAT.1 Well-defined development tools Dependencies ALC_DVS.2: no. 8.2.4 Security Requirements – Mutual Support and Internal Consistency The following part of the security requirements rationale shows that the set of security requirements for the TOE consisting of the security functional requirements (SFRs) and the security assurance requirements (SARs) together forms a mutually supportive and internally consistent whole. The analysis of the TOE´s security requirements with regard to their mutual support and internal consistency demonstrates: The dependency analysis in section 8.2.2 Dependency Rationale for the security functional requirements shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analysed, and non-satisfied Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 72 of 92 Public/öffentlich 8 Rationale dependencies are appropriately explained. The assurance class EAL4 is an established set of mutually supportive and internally consistent assurance requirements. The dependency analysis for the additional assurance components in section 8.2.3 Security Assurance Requirements Rationale shows that the assurance requirements are mutually supportive and internally consistent as all (additional) dependencies are satisfied and no inconsistency appears. The Personalization Agent may configure the TOE according to the organisational security policy (i) for use with Primary Inspection Systems or (ii) for use with Basic Inspection Systems. According to the security objective OT.Data_Conf the TOE enforces different security functional policies for the chosen (by means of the SFr FMT_MOF.1) configurations (i.e. the Primary Access Control SFP for the use with Primary Inspection Systems and the Basic Access Control SFP for the use with Basic Inspection Systems). These SFP are implemented by two internally consistent sets of SFR for the cryptographic functions, the user identification, the user authentication, the access control and - in case of the Basic Access Control SFP - for the data export protection. All TSF are protected by a common set of SFR of the FPT against any attempt to bypass, to deactivate, to manipulate or to misuse the TOE security features or TSF. Inconsistency between functional and assurance requirements could only arise if there are functional-assurance dependencies which are not met, a possibility which has been shown not to arise in sections 8.2.2 Dependency Rationale and 8.2.3 Security Assurance Requirements Rationale. Furthermore, as also discussed in section 8.2.3 Security Assurance Requirements Rationale, the chosen assurance components are adequate for the functionality of the TOE. So the assurance requirements and security functional requirements support each other and there are no inconsistencies between the goals of these two groups of security requirements. 8.2.5 Rationale for Strength of Function High The TOE shall demonstrate to be highly resistant against penetration attacks in order to meet the requirements of the Protection Profile [[21a].] (see 5.2) and its corespondent SFRs (FIA_UAU.4 , FCS_RND.1 and FPT_FLS.1). The protection against attacks with a high attack potential dictates a strength of function high rating for functions in the TOE that are realised by probabilistic or permutational mechanisms (SF.ADMIN (Administration of the TOE), SF.AUTH (Authentication of the authorized TOE user), SF.CRYPTO (Cryptographic Support), SF.IC (Security Functions of the IC)). 8.3 Rationale for TOE Summary Specification 8.3.1 Rationale for TOE Security Functions The following table gives the coverage of the TOE Security Functional Requirements by the TOE Security Functions.

FCS_CKM.1.1/ BAC_MRTD requires that the Document Basic Access Control Key Derivation Algorithmand specified cryptographic key sizes 112 bit that meet the following: [7], Annex E. are applied. SF.Crypro.1 states that DES key generation in accordance with the Document Basic Access Control Key Derivation Algorithm with key sizes of 112 bit that meet: [7], Annex E are supported by the TOE and therefore meets the above stated TOE SFR.

SF.Crypto.2 states that hashing by the TOE is performed in accordance with SHA-1that meet the following: FIPS 180-2 and therefore meets the above stated TOE SFR. FCS_COP.1.1/ TDES_MRTD requires that secure messaging – encryption and decryptionis performedin accordance with a specified cryptographic algorithm Triple- DES in CBC modeand cryptographic key sizes 112 bit that meet the following: FIPS 46-3 [14] and [7]; Annex E. SF.Crypto.3 states that secure messaging – encryption and decryption is performed with Triple-DES in CBC mode and key sizes of 112 bit that meet: FIPS 46-3 [14]and [7]; Annex E and SF. IC.4 supports the cryptographic support for DES calculations and therefore meets the above stated TOE SFR. FCS_COP.1.1/MAC_MRTD requires that secure messaging – message authentication code is performed in accordance with a specified cryptographic algorithm Retail MAC and cryptographic key sizes 112 bitthat meet the following: ISO 9797 (MAC algorithm 3, block cipher DES, Sequence Message Counter, padding mode 2). SF.Crypto.4 states that secure messaging – message authentication is performed with Retail MAC and key sizes of 112 bit that meet: ISO 9797 (MAC algorithm 3, block cipher DES, zero IV 8 bytes, padding mode 2) and therefore meets the above stated TOE SFR. FCS_RND.1.1/ MRTD requires that the TSF shall provide a mechanism to generate random numbers that meet AIS 20 [5a]. SF.Crypto.5 states that random number generation according AIS20 [5a] for key generation and authentication process is supported by the TOE and SF.IC.3 states that the TOE supports random number generation and therefore meets the above stated TOE SFR. 8.3.1.1.3 FIA_UID.1.1 , FIA_UAU.1.1 The Timing of identification and authentication is managed by TSF.ADMIN (Administration of the TOE) if the administrator is involved and additionally by TSF.AUTH (Authentication of the TOE). FIA_UID.1.1 requires that the TSF shall allow (1) to read the Initialization Data and Pre-personalization Data in Phase 2 “Manufacturing”, (2) to read the ATS in Phase 3 “Personalization of the MRTD”, (3) to read the ATS if the TOE is configured for use with Basic Inspection Systems only in Phase 4 “Operational Use”, (4) to read the logical MRTD if the TOE is configured for use with Primary Inspection System s in Phase 4 “Operational Use” on behalf of the user to be performed before the user is identified. SF.ADMIN.2 states that the TOE realises the possibility to read before user identification and authentication: - the Initialization Data in Phase 2 “Manufacturing”, - the ATR in Phase 3 “Personalization of the MRTD”, Security Target Lite STARCOS 3.01 PE V1.1/Version 1.0 / Status 10.07.2007 Page 76 of 92 Public/öffentlich 8 Rationale - the ATR if the TOE is configured for use with Basic Inspection Systems only in Phase 4 “Operational Use”, - the logical MRTD if the TOE is configured for use with Primary Inspection Systems in Phase 4 “Operational Use” and therefore meets the above stated TOE SFR. FIA_UID.1.2 requires that TSF shall require each user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user.
