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, TÜV Rheinland Nederland 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 TÜV Rheinland Nederland 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 TÜV Rheinland Nederland 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, TÜV Rheinland Nederland 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 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 MaskTech eSign Applet on Secora™ ID S v1.1 is MaskTech International GmbH located in Nuremberg, Germany 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 securely create or import, use and manage, signature creation data (SCD). The SSCD protects the SCD during its whole life cycle beginning with import as to be used in a signature creation process solely by its signatory. The TOE comprises all IT security functionality necessary to ensure the secrecy of the SCD and the security of the electronic signature. The TOE stores signatory reference authentication data (RAD) to authenticate a user as its signatory. The RAD is a password e.g. PIN, a biometric template or a combination of these. The TOE protects the confidentiality and integrity of the RAD. The TOE has been evaluated by SGS Brightsight B.V. located in Delft, The Netherlands. The evaluation was completed on 18 October 2022 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 MaskTech eSign Applet on Secora™ ID S v1.1, 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 MaskTech eSign Applet on Secora™ ID S v1.1 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) and AVA_VAN.5 (Advanced methodical vulnerability analysis). 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). TÜV Rheinland Nederland 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.

Any use or application requires prior approval. 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. A proprietary test suite was used to ensure the correctness of the personalization and the functional compliance of the TOE security policy. 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 repeated a selection of the developer tests were chosen based on representative selection of different test suites and different test configurations. 2.6.2 Independent penetration testing The methodical analysis performed was conducted along the following steps:  When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considered whether potential vulnerabilities can 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 previous evaluation classes. This resulted in the identification of (additional) potential vulnerabilities. This analysis was performed according to the attack methods in [JIL-AP] and included consideration of the technical report [HW-ETRfC] and [Plat-ERTfC] of the underlying platform.  All potential vulnerabilities were analysed using the knowledge gained from all evaluation classes and information from the public domain, including latest guidance issued on the secure use of platform components. A judgment was made on how to assure that these potential vulnerabilities are not exploitable. The potential vulnerabilities were addressed by penetration testing, an update of platform and/or TOE usage guidance or in other ways that were deemed appropriate. The total test effort expended by the evaluators was 2 weeks. During that test campaign, 100% of the total time was spent on Perturbation attacks. 2.6.3 Test configuration The TOE was tested in the following configurations:  The test samples were identified as: SECORA™ ID S v1.1 platform combined with applet ID 0x0025, which corresponds to the ePP product. The combined test plan for ePP product and eSign TOE generated assurance for perturbation attack resistance of both applet ID 0x0025 (ePP product) and applet ID 0x0013 (this TOE, eSign applet) that share the essential internal mechanisms against perturbation attacks. 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. 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 the use of three Site Technical Audit Reports. Sites involved in the development and production of the hardware platform were reused by composition. 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 MaskTech eSign Applet on Secora™ ID S v1.1. 2.9 Evaluation Results The evaluation lab documented their evaluation results in the [ETR], which references an ASE Intermediate Report and other evaluator documents. The verdict of each claimed assurance requirement is “Pass”. Based on the above evaluation results the evaluation lab concluded the MaskTech eSign Applet on Secora™ ID S v1.1, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 5 augmented with AVA_VAN.5 and ALC_DVS.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 [EN419211-2], [EN419211-3], [EN419211-4], [EN419211-5] and [EN419211-6]. 2.10 Comments/Recommendations The user guidance as outlined in section 2.5 “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. 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”. To be protected against attackers with a "high attack potential", appropriate cryptographic algorithms with sufficiently large cryptographic key sizes shall be used (references can be found in national and international documents and standards).
