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.

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the Kinibi-
510a-V007. The developer of the Kinibi-510a-V007 is Trustonic located in Valbonne, France 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 implements the core functionalities defined in GlobalPlatform TEE Internal API Specification
and Trustonic’s proprietary APIs. The TOE is a TEE operating system running on a
hardware/firmware. The hardware and firmware are not part of the TOE and are considered to be part
of the TOE environment.
The TOE has been evaluated by Riscure B.V. located in Delft, The Netherlands. The evaluation was
completed on 16 March 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 Kinibi-510a-V007, 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 Kinibi-510a-V007 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_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).
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.

2 Certification Results
2.1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this evaluation is the Kinibi-510a-V007 from Trustonic located in
Valbonne, France.
The TOE is comprised of the following main components:
Delivery
item type
Identifier Version
Software
Kinibi-Src-Exynos64-510a-V007-r0- 20211117.125042-1-2021
1117_124837_19.zip
V007
The TOE is required to run on specific hardware as specified in chapter 4.4 of the [ST].
To ensure secure usage a set of guidance documents is provided, together with the Kinibi-510a-V007.
For details, see section 2.5 “Documentation” of this report.
2.2 Security Policy
The TOE provides all the following main security features:
• Components authenticity and rollback protection
• Memory Management and Isolation mechanism
• User and device identification
• Inter-TA communication
• Secure storage of Keys and Data
• RNG, Key Management and Cryptographic operations
• Secure time
The Security Target covers two possible configurations for the TOE:
• Normal mode: This mode is in line with the GP TEE base PP. Kinibi Secure Storage is not
rollback protected and Trusted Application are not downgrade protected.
• Time&RollbackProtection (T&R) mode: Secure Storage Rollback Protection and Trusted
Application downgrade protection are enforced with the RPMB support provided by the
underlying hardware. In this configuration, the TOE enforces GP TEE Time & Rollback PP
modules security objectives.
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. 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.

2.6 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 SFR-
enforcing module level.
All parameter choices have been addressed at least once. All boundary cases identified have been
tested explicitly, and additionally the near-boundary conditions have been covered probabilistically.
The testing was largely automated using industry standard and proprietary test suites. Test scripts
were extensively used to verify that the functions return the expected values.
The test results of the underlying base TOE are extendable to composite evaluations, as the base
TOE is used according to its guidance and the composite evaluation requirements are met.
Amount of developer testing performed:
• The tests are performed on security mechanisms and on subsystem and module level with a
total amount of several thousand test scenarios.
• As demonstrated by ATE_COV.2 the developer has tested all security mechanisms and
TSFIs.
• As demonstrated by ATE_DPT.3 the developer has tested all the TSF subsystems and
modules against the TOE design and against the security architecture description.
2.6.2 Independent penetration testing
For the testing performed by the evaluators, the developer has provided samples and a test
environment. The evaluators have verified the execution of a selection of the developer tests, and
conducted a number of test cases designed by the evaluator.
The total test effort expended by the evaluators was 10 days. During that test campaign, 100% of the
total time was spent on logical tests.
2.6.3 Test configuration
The TOE configuration used for testing was the Trustonic Kinibi-510a-V007 which was the same as
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.
2.7 Reused Evaluation Results
There is no reuse of evaluation results in this certification.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number Kinibi-510a-V007. The TOE is software
only, and the validity of its source package can be verified by computing the SHA-256 of the delivered

package (as per section 2.3.1 of [AGD_PRE] mentioned in chapter 2.5 "Documentation”) and compare
with the expected value from section 2.2.2 of the [ST].
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 Kinibi-510a-V007, to be CC
Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 5 augmented with
ALC_FLR.1. This implies that the product satisfies the security requirements specified in the Security
Target [ST].
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.
