Foreword The Netherlands Scheme for Certification in the Area of IT Security (NSCIB) provides a third-party evaluation and certification service for determining the trustworthiness of Information Technology (IT) security products. Under this NSCIB, TrustCB B.V. has the task of issuing certificates for IT security products, as well as for protection profiles and sites. Part of the procedure is the technical examination (evaluation) of the product, protection profile or site according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification Body, which is operated by TrustCB B.V. in cooperation with the Ministry of the Interior and Kingdom Relations. An ITSEF in the Netherlands is a commercial facility that has been licensed by TrustCB B.V. to perform Common Criteria evaluations; a significant requirement for such a licence is accreditation to the requirements of ISO Standard 17025 “General requirements for the accreditation of calibration and testing laboratories”. By awarding a Common Criteria certificate, TrustCB B.V. asserts that the product or site complies with the security requirements specified in the associated (site) security target, or that the protection profile (PP) complies with the requirements for PP evaluation specified in the Common Criteria for Information Security Evaluation. A (site) security target is a requirements specification document that defines the scope of the evaluation activities. The consumer should review the (site) security target or protection profile, in addition to this certification report, to gain an understanding of any assumptions made during the evaluation, the IT product's intended environment, its security requirements, and the level of confidence (i.e., the evaluation assurance level) that the product or site satisfies the security requirements stated in the (site) security target.

Any use or application requires prior approval. Recognition of the Certificate The presence of the Common Criteria Recognition Arrangement (CCRA) and the SOG-IS logos on the certificate indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS Mutual Recognition Agreement (SOG-IS MRA) and will be recognised by the participating nations. International recognition The CCRA was signed by the Netherlands in May 2000 and provides mutual recognition of certificates based on the Common Criteria (CC). Since September 2014 the CCRA has been updated to provide mutual recognition of certificates based on cPPs (exact use) or STs with evaluation assurance components up to and including EAL2+ALC_FLR. For details of the current list of signatory nations and approved certification schemes, see http://www.commoncriteriaportal.org. European recognition The SOG-IS MRA Version 3, effective since April 2010, provides mutual recognition in Europe of Common Criteria and ITSEC certificates at a basic evaluation level for all products. A higher recognition level for evaluation levels beyond EAL4 (respectively E3-basic) is provided for products related to specific technical domains. This agreement was signed initially by Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy joined the SOG-IS MRA in December 2010. For details of the current list of signatory nations, approved certification schemes and the list of technical domains for which the higher recognition applies, see https://www.sogis.eu.

The developer of the Sm@rtCafé® Expert 8.0 C2 is Giesecke+Devrient Mobile Security GmbH located in Munich, Germany and Veridos Gmbh was the sponsor of the evaluation and certification. A Certification Report is intended to assist prospective consumers when judging the suitability of the IT security properties of the product for their particular requirements. The TOE described in the [ST] is a dual-interface, contact based or a pure contactless smart card with a Javacard operating system (OS). The TOE is a multi-purpose Java card where applets of different kinds can be installed. Since a post-issuance installation of applets is possible, the TOE corresponds to an open configuration, as defined in [PP]. The TOE was previously evaluated by SGS Brightsight B.V. located in Delft, The Netherlands and was certified under the accreditation of TÜV Rheinland Nederland on 01 September 2022 (CC-22- 0289060). This current evaluation of the TOE has also been conducted by SGS Brightsight B.V. and was completed on 24 May 2023 with the approval of the ETR. The certification procedure has been conducted in accordance with the provisions of the Netherlands Scheme for Certification in the Area of IT Security [NSCIB]. The major changes from previous evaluations are: - Additional Chip memory size is supported. - TOE scope is modified: RSA-PSS is added and change in RNG from DRG.4 to DRG.3 is applied. - Localized code updates. - MoC Library is removed. - Guidance updates. The security evaluation reused the evaluation results of previously performed evaluations. A full, up- to-date vulnerability analysis has been made. The scope of the evaluation is defined by the security target [ST], which identifies assumptions made during the evaluation, the intended environment for the Sm@rtCafé® Expert 8.0 C2, the security requirements, and the level of confidence (evaluation assurance level) at which the product is intended to satisfy the security requirements. Consumers of the Sm@rtCafé® Expert 8.0 C2 are advised to verify that their own environment is consistent with the security target, and to give due consideration to the comments, observations and recommendations in this certification report. The results documented in the evaluation technical report [ETR] 1 for this product provide sufficient evidence that the TOE meets the EAL6 augmented (EAL6+) assurance requirements for the evaluated security functionality. This assurance level is augmented with ALC_FLR.1 (Basic Flaw Remediation). The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 3.1 Revision 5 [CEM] for conformance to the Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 5 [CC] (Parts I, II and III). TrustCB B.V., as the NSCIB Certification Body, declares that the evaluation meets all the conditions for international recognition of Common Criteria Certificates and that the product will be listed on the NSCIB Certified Products list. Note that the certification results apply only to the specific version of the product as evaluated. 1 The Evaluation Technical Report contains information proprietary to the developer and/or the evaluator, and is not available for public review.

For detailed information on the security objectives that must be fulfilled by the TOE environment, see section 6.2 of the [ST]. 2.3.2 Clarification of scope The evaluation did not reveal any threats to the TOE that are not countered by the evaluated security functions of the product. 2.4 Architectural Information The logical architecture, originating from the Security Target [ST] of the TOE can be depicted as follows: Page: 8/13 of report number: NSCIB-CC-2300005-01-CR, dated 24 May 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. TOE Boundary Pre/Post-Issuance Applets Smart Card Platform Card Manager IC IC OS G&D Crypto Library Java Card System APDU Layer 2.5 Documentation The following documentation is provided with the product by the developer to the customer: Identifier Version Preparative Procedures Sm@rtCafé® Expert 8.0 C2 2.4 Operational User Guidance Sm@rtCafé® Expert 8.0 C2 2.6 2.6 IT Product Testing Testing (depth, coverage, functional tests, independent testing): The evaluators examined the developer’s testing activities documentation and verified that the developer has met their testing responsibilities. 2.6.1 Testing approach and depth The developer performed extensive testing on functional specification, subsystem and SFR-enforcing module level. All parameter choices were addressed at least once. All boundary cases identified were tested explicitly, and additionally the near-boundary conditions were covered probabilistically. The testing was largely automated using industry standard and proprietary test suites. Test scripts were used extensively to verify that the functions return the expected values. During this re-evaluation, the developer repeated and extended the previous test plan. The underlying hardware and crypto-library test results are extendable to composite evaluations, because the underlying platform is operated according to its guidance and the composite evaluation requirements are met. During the baseline evaluation, for the testing performed by the evaluators, the developer provided samples and a test environment. The evaluators reproduced a selection of the developer tests, as well as a small number of test cases designed by the evaluator. During this re-evaluation, the evaluator reused previous test results. 2.6.2 Independent penetration testing The independent vulnerability analysis performed was conducted along the following steps: Page: 9/13 of report number: NSCIB-CC-2300005-01-CR, dated 24 May 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. • When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considered whether potential vulnerabilities could already be identified due to the TOE type and/or specified behaviour in such an early stage of the evaluation. • For ADV_IMP a thorough implementation representation review was performed on the TOE. During this attack-oriented analysis the protection of the TOE was analysed using the knowledge gained from all evaluation classes. This resulted in the identification of (additional) potential vulnerabilities. This analysis used the attack methods in [JIL-AM] and [JIL-AAPS]. • All potential vulnerabilities were analysed using the knowledge gained from all evaluation classes and information from the public domain. A judgment was made on how to assure that these potential vulnerabilities are not exploitable. The potential vulnerabilities were addressed by penetration testing, a guidance update or in other ways that are deemed appropriate. The total test effort expended by the evaluators during the baseline evaluation was 16 weeks. During that test campaign, 13% of the total time was spent on Perturbation attacks, 79% on side-channel testing, and 8% on logical tests. Vulnerability analysis was refreshed during this evaluation, but no additional penetration tests were required as a result of this activity. 2.6.3 Test configuration During the original evaluation, the configuration of the sample used for independent evaluator testing and penetration testing was the same as described in the [ST] and in some specific cases, an earlier revision of the TOE was also used. The assurance gained from testing on an earlier revision has been assessed to be valid for the final TOE version, because the changes introduced were minimal and did not have an impact on the TSF. No testing was performed by the evaluator during this re-evaluation. 2.6.4 Test results The testing activities, including configurations, procedures, test cases, expected results and observed results are summarised in the [ETR], with references to the documents containing the full details. The developer’s tests and the independent functional tests produced the expected results, giving assurance that the TOE behaves as specified in its [ST] and functional specification. No exploitable vulnerabilities were found with the independent penetration tests. The algorithmic security level of cryptographic functionality has not been rated in this certification process, but the current consensus on the algorithmic security level in the open domain, i.e., from the current best cryptanalytic attacks published, has been taken into account. Not all key sizes specified in the [ST] have sufficient cryptographic strength for satisfying the AVA_VAN.5 “high attack potential”. The TOE supports a wider range of key sizes (see [ST]), including those with sufficient algorithmic security level to exceed 100 bits as required for high attack potential (AVA_VAN.5). The strength of the implementation of the cryptographic functionality has been assessed in the evaluation, as part of the AVA_VAN activities. For composite evaluations, please consult the [ETRfC] for details. 2.7 Reused Evaluation Results This is a re-certification. Documentary evaluation results of the earlier version of the TOE have been reused, but vulnerability analysis has been renewed. There has been extensive reuse of the ALC aspects for the sites involved in the development and production of the TOE, by use of 4 Site Technical Audit Reports. All assurance components that are needed for the sites are considered during the evaluation. In determining whether the TOE meets the EAL6+ ALC requirements, STARs were used to re-use site audit results of sites involved in the TOE life-cycle. For several production sites, these STARs were the results of audits at EAL5+. Nonetheless, the evaluator has established that the TOE meets all EAL6+ requirements, independent of which production site is used.

To support composite evaluations according to [COMP] a derived document [ETRfC] was provided and approved. This document provides details of the TOE evaluation that must be considered when this TOE is used as platform in a composite evaluation. The verdict of each claimed assurance requirement is “Pass”. Based on the above evaluation results the evaluation lab concluded the Sm@rtCafé® Expert 8.0 C2, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 6 augmented with ALC_FLR.1. This implies that the product satisfies the security requirements specified in Security Target [ST]. The Security Target claims ‘demonstrable’/’strict’ conformance to the Protection Profile [PP]. 2.10 Comments/Recommendations The user guidance as outlined in section 0 “The logical architecture, originating from the Security Target [ST] of the TOE can be depicted as follows: TOE Boundary Pre/Post-Issuance Applets Smart Card Platform Card Manager IC IC OS G&D Crypto Library Java Card System APDU Layer Documentation” contains necessary information about the usage of the TOE. Certain aspects of the TOE’s security functionality, in particular the countermeasures against attacks, depend on accurate conformance to the user guidance of both the software and the hardware part of the TOE. There are no particular obligations or recommendations for the user apart from following the user guidance. Please note that the documents contain relevant details concerning the resistance against certain attacks. In addition, all aspects of assumptions, threats and policies as outlined in the Security Target not covered by the TOE itself must be fulfilled by the operational environment of the TOE. The customer or user of the product shall consider the results of the certification within his system risk management process. For the evolution of attack methods and techniques to be covered, the customer should define the period of time until a re-assessment for the TOE is required and thus requested from the sponsor of the certificate.
