The SOMA_80IFX is utilized by Machine Readable Travel Documents (MRTD) based on the requirements and recommendations of the international Civil Aviation Organisation (ICAO). The TOE provides the Basic Access Control according to the Technical Report: PKI for MRTD offering ICC-Read only Access [11] and is supplied with a file system that contains all the data that are used in the context of the ICAO application as described in the Protection Profile Machine Readable Travel Document with “ICAO Application”, Basic Access Control [10]. The Security Target [6] is the basis for this certification. It is based on the certified Protection Profile Protection Profile for Machine Readable Travel Document with "ICAO Application", Basic Access Control Version 1.0, BSI-PP-0017-2005 [10]. The TOE Security Assurance Requirements (SAR) are based entirely on the assurance components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details). The TOE meets the Assurance Requirements of the Evaluation Assurance Level EAL 4 augmented by ADV_IMP.2 und ALC_DVS.2. The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the Security Target [6] and [9], chapter 7.1. They are selected from Common Criteria Part 2 and some of them are newly defined. Thus the TOE is CC Part 2 extended. The Security Functional Requirements (SFR) relevant for the IT-Environment of the TOE are outlined in the Security Target [6] and [9], chapter 7.3. The TOE Security Functional Requirements are implemented by the following TOE Security Functions: TOE Security Function Addressed issue SF1 Agents Identification and Authentication SF2 Data exchange with Secure Messaging SF3 Access Control of stored Data Objects SF4 Life cycle management SF5 Software integrity check of TOE’s assets SF6 Security functions provided by the hardware Table 1: TOE Security Functions For more details please refer to the Security Target [6] and [9], chapter 8.2. The claimed TOE’s Strength of Functions 'high' (SOF-high) for specific functions as indicated in the Security Target [6] and [9], chapter 8.2 is confirmed. The rating of the Strength of Functions does not include the cryptoalgorithms suitable for encryption and decryption (see BSIG Section 9, Para. 4, Clause 2). For details see chapter 9 of this report. The assets to be protected by the TOE are defined in the Security Target [6] and [9], chapter 4.1.1. Based on these assets the TOE Security Environment is defined in terms of Assumptions, Threats and Organisational Security Policies. This is outlined in the Security Target [6] and [9], chapter 4. This certification covers the following configurations of the TOE: 12 / 36 BSI-DSZ-CC-0498-2009 Certification Report SOMA_80IFX 1.1.0 consisting of: ● IFX Chip SLE66CLX800PE, ● embedded software operation system SOMA_80IFX 1.1.0, ● a file system in the context of the ICAO application. After delivery the TOE only features one fixed configuration, which cannot be altered by the user/administrator. The certification results only apply to the version of the product indicated in the certificate and on the condition that all the stipulations are kept as detailed in this Certification Report. This certificate is not an endorsement of the IT product by the Federal Office for Information Security (BSI) or any other organisation that recognises or gives effect to this certificate, and no warranty of the IT product by BSI or any other organisation that recognises or gives effect to this certificate, is either expressed or implied. 2 Identification of the TOE The Target of Evaluation (TOE) is called: SOMA_80IFX Version 1.1.0 The TOE consists of an integrated circuit inserted between two paper sheets, which also embed an antenna for wireless communication. The resulting sandwich is called “inlay” and can be bound to the cover of a passport booklet. The following table outlines the TOE deliverables: No Type Identifier Release Form of Delivery 1 HW + SW TOE: SOMA_80IFX, consisting of: • SW: SOMA_80IFX OS • HW: SLE66CLX800PE 1.1.0 Software contained in the chip, chip mounted into an inlay package and initialised. 2 DOC SOMA_80IFX e-Passport User Guidance 1.1.1 Document in electronic form as PDF 3 DOC SOMA_80IFX e-Passport Administrator Guide 1.1.1 Document in electronic form as PDF Table 2: Deliverables of the TOE The TOE is delivered after the initialisation. The following items are shipped to the Personalisation Agent: ● fully-functional and already initialized, but not operational SOMA_80IFX inlays ● The master key required to derive the Personalization Keys at runtime. ● Secure Access Module (SAM, if used for the delivery of the master key) ● SAM activation codes (SAC, if a SAM is used to deliver the master key) ● The Administrator Guidance ● The User Guidance The master key is delivered according to Custormer’s requirements. The use of a Secure Access Module (SAM) is a possible solution. The SAM is a smart card and during 13 / 36 Certification Report BSI-DSZ-CC-0498-2009 the delivery the Personalization Keys generation is disabled and a SAM Activation Code (SAC) must be used to enable that functionality. Inlays, SAMs (if used) and CD-ROMs are shipped separately by means of a courier trusted by Gep. The SAM Activation Codes (if required) are delivered to the Personalisation Agent by means of PGP enciphered e-mail messages. The TOE identification data (SOMA_80IFX 1.1.0) is located in the non-volatile memory of the chip and can be read by means of the administrative command GET DATA. The TOE is uniquely identified by a string of bytes as follows: ● OS identifier: 53h 4Fh 4Dh 41h ● IC identifier: 38h 30h 49h 46h 58h ● OS version: 31h 2Eh 31h 2Eh 30h 3 Security Policy The security policy of the TOE is defined according to the MRTD BAC PP [10] by the security objectives and requirements for the contactless chip of machine readable travel documents (MRTD) based on the requirements and recommendations of the International Civil Aviation Organisation (ICAO). It addresses the advanced security methods Basic Access Control in the technical reports of the ICAO New Technology Working Group. 4 Assumptions and Clarification of Scope The Assumptions defined in the Security Target and some aspects of Threats and Organisational Security Policies are not covered by the TOE itself. These aspects lead to specific Security Objectives to be fulfilled by the TOE-Environment. The following topics are of relevance: Development and Manufactoring Environment ● Assurance Security Measures in Development and Manufacturing Environment ● Control over MRTD Material Issuing State or Organization ● Personalization of logical MRTD ● Authentication of logical MRTD by Signature ● Administration of logical MRTD Receiving State or Organization ● Examination of the MRTD passport book ● Verification by Passive Authentication ● Protection of data of the logical MRTD MRTD Holder ● Secure Handling of the MRTD holder Details can be found in the Security Target [6] and [9] chapter 5.2. 14 / 36 BSI-DSZ-CC-0498-2009 Certification Report 5 Architectural Information The architecture of the Operating System embedded in the chip and the OS has been designed following a layered approach. In a bottom to top view, i.e. from the physical layer to the applicative layer, following layers are defined: ● Layer 1: HL - Hardware Layer The HL is the hardware chip. The interface to the HAL layer is constituted by the processor instructions set (ISA) and a specific library file supplied by the Infineon Technologies AG, i.e. the Resource Management System. It contains a set of subroutines for programming the integrated EEPROM along with others functions who offer a sophisticated interface to upper layer. ● Layer 2: HAL - Hardware Abstraction Layer The HAL is in charge to manage the functionality directly related with the chip- dependent hardware. Therefore it performs actions on the hardware and provides exposed services like APIs to the upper layer. ● Layer 3: DOL - Data Objects Layer The DOL attends to abstract the physical organization of the data structures (objects) stored in EEPROM memory area. It provides to the upper layer the services to manage the card objects and data stored within these. ● Layer 4: SSML - Security Services Management Layer This layer provides additional services necessary to support card applicative features which are the security status of the card, authentication objects (i.e. keys), the security environment and the secure messaging. ● Layer 5: CML - Command Management Layer The most external layer offers the externally visible interface by means of the APDU commands. 6 Documentation The evaluated documentation as outlined in table 2 is being provided with the product to the customer. This documentation contains the required information for secure usage of the TOE in accordance with the Security Target. Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of this report have to be followed. 7 IT Product Testing 7.1 Developer's Test according to ATE_FUN The developer’s testing effort is summarized in the following 4 aspects: TOE configurations tested: ● The tests were performed with the composite smartcard product SOMA_80IFX 1.1.0 consisting of the Infineon Chip SLE66CLX800PE, operational system SOMA_80IFX and a file system in the context of the ICAO application.

This conformance result is presented with respect to CC Part 2 (functional requirements), CC Part 3 (assurance requirements) and, if applicable, to a pre-defined set of requirements (e.g., EAL, Protection Profile). The conformance result consists of one of the following: – CC Part 2 conformant - A PP or TOE is CC Part 2 conformant if the functional requirements are based only upon functional components in CC Part 2. – CC Part 2 extended - A PP or TOE is CC Part 2 extended if the functional requirements include functional components not in CC Part 2. plus one of the following: – CC Part 3 conformant - A PP or TOE is CC Part 3 conformant if the assurance requirements are based only upon assurance components in CC Part 3. – CC Part 3 extended - A PP or TOE is CC Part 3 extended if the assurance requirements include assurance requirements not in CC Part 3. Additionally, the conformance result may include a statement made with respect to sets of defined requirements, in which case it consists of one of the following: – Package name Conformant - A PP or TOE is conformant to a pre-defined named functional and/or assurance package (e.g. EAL) if the requirements (functions or assurance) include all components in the packages listed as part of the conformance result. – Package name Augmented - A PP or TOE is an augmentation of a pre-defined named functional and/or assurance package (e.g. EAL) if the requirements (functions or assurance) are a proper superset of all components in the packages listed as part of the conformance result. Finally, the conformance result may also include a statement made with respect to Protection Profiles, in which case it includes the following: – PP Conformant - A TOE meets specific PP(s), which are listed as part of the conformance result.“ 25 / 36 Certification Report BSI-DSZ-CC-0498-2009 CC Part 3: Protection Profile criteria overview (chapter 8.2) “The goal of a PP evaluation is to demonstrate that the PP is complete, consistent, technically sound, and hence suitable for use as a statement of requirements for one or more evaluatable TOEs.

The CC approach identifies the separate concepts of assurance in a TOE at the end of the evaluation, and of maintenance of that assurance during the operational use of the TOE. It is important to note that not all families and components from CC Part 3 are included in the EALs. This is not to say that these do not provide meaningful and desirable assurances. Instead, it is expected that these families and components will be considered for augmentation of an EAL in those PPs and STs for which they provide utility.” Evaluation assurance level (EAL) overview (chapter 11.1) “Table 6 represents a summary of the EALs. The columns represent a hierarchically ordered set of EALs, while the rows represent assurance families. Each number in the resulting matrix identifies a specific assurance component where applicable. As outlined in the next section, seven hierarchically ordered evaluation assurance levels are defined in the CC for the rating of a TOE's assurance. They are hierarchically ordered inasmuch as each EAL represents more assurance than all lower EALs. The increase in assurance from EAL to EAL is accomplished by substitution of a hierarchically higher assurance component from the same assurance family (i.e. increasing rigour, scope, and/or depth) and from the addition of assurance components from other assurance families (i.e. adding new requirements). These EALs consist of an appropriate combination of assurance components as described in chapter 7 of this Part 3. More precisely, each EAL includes no more than one component of each assurance family and all assurance dependencies of every component are addressed. While the EALs are defined in the CC, it is possible to represent other combinations of assurance. Specifically, the notion of “augmentation” allows the addition of assurance components (from assurance families not already included in the EAL) or the substitution of assurance components (with another hierarchically higher assurance component in the same assurance family) to an EAL. Of the assurance constructs defined in the CC, only EALs may be augmented. The notion of an “EAL minus a constituent assurance component” is not recognised by the standard as a valid claim. Augmentation carries with it the obligation on the part of the claimant to justify the utility and added value of the added assurance component to the EAL. An EAL may also be extended with explicitly stated assurance requirements. 28 / 36 BSI-DSZ-CC-0498-2009 Certification Report Assurance Class Assurance Family Assurance Components by Evaluation Assurance Level EAL1 EAL2 EAL3 EAL4 EAL5 EAL6 EAL7 Configuration management ACM_AUT 1 1 2 2 ACM_CAP 1 2 3 4 4 5 5 ACM_SCP 1 2 3 3 3 Delivery and operation ADO_DEL 1 1 2 2 2 3 ADO_IGS 1 1 1 1 1 1 1 Development ADV_FSP 1 1 1 2 3 3 4 ADV_HLD 1 2 2 3 4 5 ADV_IMP 1 2 3 3 ADV_INT 1 2 3 ADV_LLD 1 1 2 2 ADV_RCR 1 1 1 1 2 2 3 ADV_SPM 1 3 3 3 Guidance documents AGD_ADM 1 1 1 1 1 1 1 AGD_USR 1 1 1 1 1 1 1 Life cycle support ALC_DVS 1 1 1 2 2 ALC_FLR ALC_LCD 1 2 2 3 ALC_TAT 1 2 3 3 Tests ATE_COV 1 2 2 2 3 3 ATE_DPT 1 1 2 2 3 ATE_FUN 1 1 1 1 2 2 ATE_IND 1 2 2 2 2 2 3 Vulnerability assessment AVA_CCA 1 2 2 AVA_MSU 1 2 2 3 3 AVA_SOF 1 1 1 1 1 1 AVA_VLA 1 1 2 3 4 4 Table 6: Evaluation assurance level summary” 29 / 36 Certification Report BSI-DSZ-CC-0498-2009 Evaluation assurance level 1 (EAL1) - functionally tested (chapter 11.3) “Objectives EAL1 is applicable where some confidence in correct operation is required, but the threats to security are not viewed as serious. It will be of value where independent assurance is required to support the contention that due care has been exercised with respect to the protection of personal or similar information. EAL1 provides an evaluation of the TOE as made available to the customer, including independent testing against a specification, and an examination of the guidance documentation provided. It is intended that an EAL1 evaluation could be successfully conducted without assistance from the developer of the TOE, and for minimal outlay. An evaluation at this level should provide evidence that the TOE functions in a manner consistent with its documentation, and that it provides useful protection against identified threats.” Evaluation assurance level 2 (EAL2) - structurally tested (chapter 11.4) “Objectives EAL2 requires the co-operation of the developer in terms of the delivery of design information and test results, but should not demand more effort on the part of the developer than is consistent with good commercial practice. As such it should not require a substantially increased investment of cost or time. EAL2 is therefore applicable in those circumstances where developers or users require a low to moderate level of independently assured security in the absence of ready availability of the complete development record. Such a situation may arise when securing legacy systems, or where access to the developer may be limited.” Evaluation assurance level 3 (EAL3) - methodically tested and checked (chapter 11.5) “Objectives EAL3 permits a conscientious developer to gain maximum assurance from positive security engineering at the design stage without substantial alteration of existing sound development practices. EAL3 is applicable in those circumstances where developers or users require a moderate level of independently assured security, and require a thorough investigation of the TOE and its development without substantial re-engineering.” 30 / 36 BSI-DSZ-CC-0498-2009 Certification Report Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed (chapter 11.6) “Objectives EAL4 permits a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, though rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 is therefore 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.” Evaluation assurance level 5 (EAL5) - semiformally designed and tested (chapter 11.7) “Objectives EAL5 permits a developer to gain maximum assurance from security engineering based upon rigorous commercial development practices supported by moderate application of specialist security engineering techniques. Such a TOE will probably be designed and developed with the intent of achieving EAL5 assurance. It is likely that the additional costs attributable to the EAL5 requirements, relative to rigorous development without the application of specialised techniques, will not be large. EAL5 is therefore applicable in those circumstances where developers or users require a high level of independently assured security in a planned development and require a rigorous development approach without incurring unreasonable costs attributable to specialist security engineering techniques.” Evaluation assurance level 6 (EAL6) - semiformally verified design and tested (chapter 11.8) “Objectives EAL6 permits developers to gain high assurance from application of security engineering techniques to a rigorous development environment in order to produce a premium TOE for protecting high value assets against significant risks. EAL6 is therefore applicable to the development of security TOEs for application in high risk situations where the value of the protected assets justifies the additional costs.” 31 / 36 Certification Report BSI-DSZ-CC-0498-2009 Evaluation assurance level 7 (EAL7) - formally verified design and tested (chapter 11.9) “Objectives EAL7 is applicable to the development of security TOEs for application in extremely high risk situations and/or where the high value of the assets justifies the higher costs. Practical application of EAL7 is currently limited to TOEs with tightly focused security functionality that is amenable to extensive formal analysis.“ Strength of TOE security functions (AVA_SOF) (chapter 19.3) “Objectives Even if a TOE security function cannot be bypassed, deactivated, or corrupted, it may still be possible to defeat it because there is a vulnerability in the concept of its underlying security mechanisms. For those functions a qualification of their security behaviour can be made using the results of a quantitative or statistical analysis of the security behaviour of these mechanisms and the effort required to overcome them. The qualification is made in the form of a strength of TOE security function claim.” Vulnerability analysis (AVA_VLA) (chapter 19.4) "Objectives Vulnerability analysis is an assessment to determine whether vulnerabilities identified, during the evaluation of the construction and anticipated operation of the TOE or by other methods (e.g. by flaw hypotheses), could allow users to violate the TSP. Vulnerability analysis deals with the threats that a user will be able to discover flaws that will allow unauthorised access to resources (e.g. data), allow the ability to interfere with or alter the TSF, or interfere with the authorised capabilities of other users.” "Application notes A vulnerability analysis is performed by the developer in order to ascertain the presence of security vulnerabilities, and should consider at least the contents of all the TOE deliverables including the ST for the targeted evaluation assurance level. The developer is required to document the disposition of identified vulnerabilities to allow the evaluator to make use of that information if it is found useful as a support for the evaluator's independent vulnerability analysis.” “Independent vulnerability analysis goes beyond the vulnerabilities identified by the developer. The main intent of the evaluator analysis is to determine that the TOE is resistant to penetration attacks performed by an attacker possessing a low (for AVA_VLA.2 Independent vulnerability analysis), moderate (for AVA_VLA.3 Moderately resistant) or high (for AVA_VLA.4 Highly resistant) attack potential.” 32 / 36 BSI-DSZ-CC-0498-2009 Certification Report D Annexes List of annexes of this certification report Annex A: Security Target provided within a separate document.
