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.

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the SteID
JC Open OS v1.0, version 1.3.2. The developer of the SteID JC Open OS v1.0, version 1.3.2 is
STMicroelectronics S.r.l located in Marcianise, Italy 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 an embedded secure element (eSE) with a Java Card System compliant with Java Card
protection profile [PP]. It is designed to host and manage Java Card applets from different
stakeholders.
The TOE has been evaluated by SGS Brightsight B.V. located in Delft, The Netherlands. The
evaluation was completed on 18 December 2025 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 SteID JC Open OS v1.0, version 1.3.2, 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 SteID JC Open OS v1.0, version 1.3.2
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.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

cryptographic functionality.
• Generation of Random Numbers. Secure random number generation mechanisms
compliant to PTG.2 Class and DRG.3 Class.
• PIN. The TOE implements secure PIN compare functions and PIN integrity protection;
• Firmware upgrade. The product also relies on IC’s certified secure loader to patch the
operational OS firmware at OEM factory or on the field.
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 4.1.2 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 TOE architecture according to the [ST] is shown in the following figure:
2.5 Documentation
The following documentation is provided with the product by the developer to the customer:
Identifier Version
STeID JC Open OS v1.0 Operational Guidance (AGD_OPE) rev. 3
STeID JC Open OS v1.0 Preparative Procedure (AGD_PRE) rev. 3
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
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.
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
The total test effort expended by the evaluators was 10 weeks. During that test campaign, 20% of the
total time was spent on Perturbation attacks, 70% on side-channel testing, and 10% on logical tests.
2.6.3 Test configuration
The configuration of the sample used for independent evaluator testing and penetration testing 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.
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
There is no reuse of evaluation results in this certification.
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 SteID JC Open OS v1.0, version 1.3.2.
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 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 SteID JC Open OS v1.0,
version 1.3.2, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of
EAL 6 augmented with ALC_FLR.2. This implies that the product satisfies the security requirements
specified in Security Target [ST].
The Security Target claims ‘demonstrable’ conformance to the Protection Profile [PP].
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).
