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 license 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, in order 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 and SOG-IS logos on the certificate
indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS
agreement and will be recognised by the participating nations.
International recognition
The CCRA has been signed by the Netherlands in May 2000 and provides mutual recognition of
certificates based on the CC. Starting 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. The current list of signatory nations and approved certification
schemes can be found on: http://www.commoncriteriaportal.org.
European recognition
The European SOGIS-Mutual Recognition Agreement (SOGIS-MRA) version 3 effective from April
2010 provides mutual recognition of Common Criteria and ITSEC certificates at a basic evaluation
level for all products. A higher recognition level for evaluation levels beyond EAL4 (resp. E3-basic) is
provided for products related to specific technical domains. This agreement was initially signed by
Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy
joined the SOGIS-MRA in December 2010. The current list of signatory nations, approved certification
schemes and the list of technical domains for which the higher recognition applies can be found on:

2.3 Assumptions and Clarification of Scope
2.3.1 Assumptions
The assumptions defined in the Security Target are not covered by the TOE itself. These aspects lead
to specific Security Objectives to be fulfilled by the TOE-Environment. Detailed information on these
security objectives that must be fulfilled by the TOE environment can be found in section 4.2 of the
[ST].
2.3.2 Clarification of scope
This TOE is dependent on the operational environment to provide countermeasures. The guidance
must be carefully applied as detailed in section 2.10. There are no further particular obligations or
recommendations for the user apart from following the user guidance.
There are major deviations between the product and the TOE, i.e security functionality that is placed
out of scope. Details are listed in chapter 2.4.

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 has performed extensive testing on functional specification, subsystem and module
level. The testing has been performed in four categories:
• Hardware: simulation tests, sample tests, wafer tests, qualification and characterization tests;
• CMS: simulation sample: simulation tests, sample tests, wafer tests
• Cryptographic and functional library: simulation sample: simulation tests, sample tests, wafer
tests
• Lib File API library: simulation sample: simulation tests, sample tests, wafer tests
All TSFIs, subsystems and modules have been tested.
For the testing performed by the evaluator, the developer has provided samples. The evaluator has
witnessed some tests at developer site and performed some evaluator-defined tests. One evaluator-
defined test has been performed at developer’s premises. The remaining ones have been performed
at Brightsight premises using own tools.
The provided samples were not always the final TOE. A rationale has been given why these test
results are still applicable for the TOE. All test results were as expected. In addition, two verification
tests have been performed to demonstrate that changes made to the IC Dedicated Software have no
security impact and penetration tests would have the same outcome.
It should be noted that developer testing has been performed on the actual TOE.
2.6.2 Independent Penetration Testing
The methodical vulnerability analysis performed was conducted along the following steps:
• When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considers
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 is performed on the TOE.
During this attack oriented analysis the protection of the TOE is analysed using the knowledge
gained from all previous evaluation classes. This results in the identification of (additional)
potential vulnerabilities. For this analysis will be performed according to the attack methods in
[JIL-AAPS].
• All potential vulnerabilities are 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 are addressed by
penetration testing, a guidance update or in other ways that are deemed appropriate.
In total 13 tests have been performed, 5 pertubation attack tests, 6 side channel attack tests, and 2
verification tests (sensors, RNG). The overall time spent for penetration testing was approx. 190 days.

2.6.3 Test Configuration
The provided samples for evaluator independent and penetration testing were not always the final
TOE. The differences between these configurations and the TOE have been analysed. A rationale has
been given why these test results are still applicable for the TOE. No tools/setups have been provided
by the developer.
2.6.4 Testing 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 as long as the
guidance requirements have been rigorously applied. For more details refer to section 2.10.
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. So, no exploitable vulnerabilities were found with the
independent penetration tests.
For composite evaluations, please consult the [ETRfC] for details.
2.7 Re-used evaluation results
There is re-use of evaluation results in this certification. All five sites involved in the development and
production of the TOE have previously been audited and Site Technical Audit Reports were created.
The Site Technical Audit Reports for the sites [STAR_HED], [STAR_HB], [STAR_CESC],
[STAR_SMIC-B], and [STAR_SMIC-S] 2 have been used for this certification.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number CIU9872B_01 C14. In [AGD_PRE]
section 3.2 the verification method of the TOE identifier is described.
2.9 Results of the Evaluation
The evaluation lab documented their evaluation results in the [ETR] which references a ASE
Intermediate Report and other evaluator documents. To support composite evaluations according to
[CCDB-2007-09-01] a derived document [ETRfC] was provided and approved. This document
provides details of the TOE evaluation that have to 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 CIU9872B_01 C14, 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 ’strict’ conformance to the Protection Profile [PP].
2 The Site Technical Audit Report contains information necessary to an evaluation lab and certification
body for the reuse of the site audit report in a TOE evaluation.

2.10 Comments/Recommendations
The user guidance as outlined in section 2.5 contains necessary information about the usage of the
TOE.
This TOE is critically dependent on the operational environment to provide
countermeasures against specific attacks as described in [AGD_OPE] chapter 8.7, 8.8, 8.9, 8.11,
8.12, and 8.13. As such it is vital that meticulous adherence to the user guidance of both the software
and the hardware part of the TOE is maintained.
There are no further particular obligations or recommendations for the user apart from following the
user guidance. Please note that the documents contain relevant details with respect to 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 need to 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. In order for the evolution of attack methods and techniques to be covered, he
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: OSCCA SM2, OSCCA SM3 and OSCCA SM4.
Not all key sizes specified in the [ST] have sufficient cryptographic strength for satisfying the
AVA_VAN.5 “high attack potential”. In order 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).
