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.

Recognition of the Certificate 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 STRONGV3P10_In04lpe of S5AV920/S5AV820/S5AV720 with specific IC Dedicated Software, version 2.0 and 2.1 is SAMSUNG Electronics Co. Ltd. located in Hwaseong-si, South Korea and they also act as 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 is a Secure Sub-System (3S), implemented in a SoC as defined in the Protection Profile [PP]. The TOE implements a processing unit, security components as well as volatile and non-volatile memories (hardware). The TOE also comprises dedicated firmware for loading the composite software from TOE-external memories and software components for cryptographic purposes and random number generation. The evaluation and certification of this TOE was performed to support reuse of the 3S into the final SoC that is targeting conformance to [PP] to fulfil the composition requirements [COMP]. The TOE has dependencies to be considered when integrated into the final SoC that need to be verified before the TOE is fully integrated into the final SoC. In accordance with [PP] integration guidance [AGD_IIG] is provided for the TOE. The users of the TOE, developers of the SoC, must strictly follow the guidance and must successfully pass an (integration) certification of this 3S TOE integrated in the final SoC in order for the 3S SoC product to claim EAL5+ and/or AVA_VAN.5 resistance and before starting a subsequent composite evaluation with its Embedded Software (ES). The TOE has been evaluated by TÜV Informationstechnik GmbH located in Essen, Germany. The evaluation was completed on 11 December 2024 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 scope of the evaluation is defined by the security target [ST], which identifies assumptions made during the evaluation, the intended environment for the STRONGV3P10_In04lpe of S5AV920/S5AV820/S5AV720 with specific IC Dedicated Software, version 2.0 and 2.1, 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 STRONGV3P10_In04lpe of S5AV920/S5AV820/S5AV720 with specific IC Dedicated Software, version 2.0 and 2.1 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 EAL5 augmented (EAL5+) assurance requirements for the evaluated security functionality. This assurance level is augmented with ALC_DVS.2 (Sufficiency of security measures), AVA_VAN.5 (Advanced methodical vulnerability analysis) and ALC_FLR.2 (Flaw Reporting Procedures). 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.

These aspects lead to specific Security Objectives to be fulfilled by the TOE-Environment. For detailed information on the security objectives that must be fulfilled by the TOE environment, see section 4.2 of the [ST-Lite]. 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. The TOE has dependencies to be considered when integrated into the final SoC that need to be verified before the TOE is fully integrated into the final SoC. The evaluation and certification of this TOE was performed to support reuse of the 3S into the final SoC that is targeting conformance to [PP] to fulfil the composition requirements [COMP]. The integration of the TOE into the specific final SoC is out of the scope for this evaluation. During integration of the 3S into the final SoC, specific evaluation activities must be performed. The [ETRfI] and the integration guidance [AGD_IIG]) were generated to support this process. 2.4 Architectural Information A simplified TOE architecture, originating from the Security Target [ST-Lite] of the TOE can be depicted as follows: Page: 8/13 of report number: NSCIB-CC-2300043-01-CR, dated 11 December 2024 ® TrustCB is a registered trademark. Any use or application requires prior approval. 2.5 Documentation The following documentation is provided with the product by the developer to the customer: Identifier Version KITT2 HW DTRNG FRO M and DTRNG FRO M Library Application Note 1.2 PKA Library API Manual (AH0 Secure RSA/ECC/SHA Library API Manual) 1.05 STRONGV3P10 of S5AV920 32-bit RISC Microcontroller for Secure Element Platform User’s Manual 0.4 Security Application Note For STRONGV3P10 for S5AV920 0.8 S5AV920 Chip Delivery Specification 0.0 STRONG Secure Bootloader Manual for S5AV920 1.03 CORTEX-M35P Reference manual 0.0 Integration Guide 0.6 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.

Any use or application requires prior approval. 2.6.1 Testing approach and depth The developer performed extensive testing on functional specification, subsystem and 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. 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. 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. 2.6.2 Independent penetration testing Based on a list of potential vulnerabilities applicable to the TOE in its operational environment created during vulnerability analysis the evaluators devised the attack scenarios for penetration tests when they were of the opinion, that those potential vulnerabilities could be exploited in the TOE’s operational environment. While doing this, also the aspects of the security architecture were considered for penetration testing. Source code reviews of the provided implementation representation accompanied the development of test cases and were used to find input for testing. The code inspection also supported the testing activities because they enabled the evaluator to verify implementation aspects that could hardly be covered by test cases. For penetration testing the evaluator took all security functionalities into consideration. Intensive penetration testing was planned based on the analysis results and performed for the underlying mechanisms of security functionalities. The total test effort expended by the evaluator was 132 person days or 18.86 weeks. During that test campaign, 2% of the total time was spent on physical attacks, 5% overcoming sensors and filters, 18% perturbation attacks, 26% retrieving keys with FA, 37% side-channel attacks, 5% exploitation of test features, 7% attacks on RNG. 2.6.3 Test configuration The configuration of the sample used for independent evaluator testing and penetration testing was performed on a test vehicle that was consistent with the TOE components described in the [ST]. 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 SoC integration) evaluations of the TOE integrated in the final SoC environment, please consult the [ETRfI] for details. For embedded SW composite evaluations, please consult the [ETRfC] for details. Page: 10/13 of report number: NSCIB-CC-2300043-01-CR, dated 11 December 2024 ® TrustCB is a registered trademark. Any use or application requires prior approval. 2.7 Reused Evaluation Results There has been extensive reuse of the ALC aspects for the sites involved in the development and production of the TOE, by use of multiple site certificates and Site Technical Audit Reports. No sites have been visited as part of this evaluation. 2.8 Evaluated Configuration The TOE is defined uniquely by its name and version number STRONGV3P10_In04lpe of S5AV920/S5AV820/S5AV720 with specific IC Dedicated Software, version 2.0 and 2.1. 2.9 Evaluation Results The evaluation lab documented their evaluation results in the [ETR], which references an ASE Intermediate Report and other evaluator documents. To support integration evaluations to an SoC a derived document [ETRfI] was provided and approved. To support future 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 the integrated 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 STRONGV3P10_In04lpe of S5AV920/S5AV820/S5AV720 with specific IC Dedicated Software, version 2.0 and 2.1, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 5 augmented with AVA_VAN.5, ALC_DVS.2 and ALC_FLR.2. This implies that the product satisfies the security requirements specified in Security Target [ST]. The Security Target claims ’strict’ conformance to the Protection Profile [PP]. 2.10 Comments/Recommendations The user guidance as outlined in section 2.5 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. The evaluation and certification of this TOE was performed to support reuse of the 3S into the final SoC that is targeting conformance to [PP] to fulfil the composition requirements [COMP]. The TOE has dependencies to be considered when integrated into the final SoC that need to be verified before the TOE is fully integrated into the final SoC. In accordance with [PP] integration guidance [AGD_IIG] is provided for the TOE. The users of the TOE, developers of the SoC, must strictly follow the guidance and must successfully pass an (integration) certification of this 3S TOE integrated in the final SoC in order for the 3S SoC product to claim EAL5+ and/or AVA_VAN.5 resistance and before starting a subsequent composite evaluation with its Embedded Software (ES). 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. The strength of the cryptographic algorithms and protocols was not rated in the course of this evaluation. This specifically applies to the following proprietary or non-standard algorithms, protocols and implementations: none. Not all key sizes specified in the [ST] have sufficient cryptographic strength to satisfy the AVA_VAN.5 “high attack potential”.
