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
SLM10TLD002Y design step A12 with CALYPSO™ move software. The developer of the
SLM10TLD002Y design step A12 with CALYPSO™ move software is Infineon Technologies AG
located in Neubiberg, 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 is a Calypso Basic product, a contactless smartcard, running a single Calypso Basic
application that is functionally compliant with the Calypso Basic specification [C-BASIC]. Such
products focus on providing access to public transportation and possibly other associated services
that can be combined into a transport title or ticket.
The TOE has been evaluated by TÜV Informationstechnik GmbH located in Essen, Germany. The
evaluation was completed on 29 November 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 SLM10TLD002Y design step A12 with
CALYPSO™ move software, 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 SLM10TLD002Y design step A12 with CALYPSO™ move software 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 EAL2 augmented (EAL2+) assurance requirements for the evaluated
security functionality. This assurance level is augmented ALC_DVS.1 (identification of security
measures) and AVA_SPECIFIC.1 (as defined in [PP] section 6.2 “AVA_SPECIFIC –Vulnerability
analysis of Calypso Basic products”).
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 SLM10TLD002Y design step A12 with
CALYPSO™ move software from Infineon Technologies AG located in Neubiberg, Germany.
The TOE is comprised of the following main components:
Delivery
item type
Identifier Version
Hardware SLM10TLD002Y
Platform ID: 0x51
(product name)
DSI: 0x0C (corresponds
to design step A12)
Software Calypso™ move software
Version: 0x02
Revision: 0x01
To ensure secure usage a set of guidance documents is provided, together with the SLM10TLD002Y
design step A12 with CALYPSO™ move software. For details, see section 2.5 “Documentation” of this
report.
For a detailed and precise description of the TOE lifecycle, see the [ST], Chapter 1.4.5.
2.2 Security Policy
The TOE provides the following features:
• Cryptographic support: RNG (True Random Number Generator PTG.1), MAC authentication
mechanism based on TDES with dual key (112 Bit)
• Key hierarchy of cryptographic static secret keys: debit key, load key and issuer key are the static
secret keys. The debit key’s access rights are a subset of the load key’s access rights. The load
key’s access rights are a subset of the issuer key’s access rights.
• Session key derivation and monotonic transaction counter to limit the usage of the static
application keys (Issuer key, Load key and Debit key)
• Session authentication mechanism: each transaction is MACed. The MAC is based on a session
key derived from one of the static keys, random challenge and transaction counter
• File access control mechanism based on the static application keys: access conditions are
mapped to commands and file types. Access conditions can be “always” (command can be
performed outside a secure session), “never” (command cannot be performed for the mapped file
type) or session (command can only be executed within a secure session) indicating the
hierarchically lowest required static key for authentication.
• Session atomicity, i.e. rollback of file modifications in case of secure session failure except
transaction counter
• Integrity protected ratification status in order to prevent abuse of ratification status to gain
unallowed access.
• Secured management of static application keys in NVM
• Robust set of sensors and detectors for the purpose of monitoring proper chip operating
conditions.
• Hardware enabled program flow integrity protection mechanism
• Test entry protection
• Peripheral locking via a Memory Management Unit to prevent unallowed peripheral accesses
• NVM integrity protection

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 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 following figure depicts the main TOE architecture. Note that Test code (TESTMODE) is
deactivated before entering pre-personalisation phase.
2.5 Documentation
The following documentation is provided with the product by the developer to the customer:
Identifier Version Date
CALYPSO™ move, Extended Datasheet 1.1 2022-07-15

2.6.1 Testing approach and depth
The developer performed extensive testing on functional specification. All TSFs and related security
mechanisms, subsystems and modules were tested in order to assure complete coverage of all SFRs.
For the testing performed by the evaluators, the developer provided samples and a test environment.
The evaluators reproduced a selection of the developer tests. In addition, a small number of test cases
designed by the evaluator were also performed.
2.6.2 Independent penetration testing
For penetration testing the evaluators 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 penetration tests covered semi-invasive attacks (i.e. laser
fault injection) and non-invasive attacks (leakage analysis).
The total test effort expended by the evaluators was 11 weeks. During that test campaign, 50% of the
total time was spent on Perturbation attacks, 28% on side-channel testing, and 22% on logical tests.
2.6.3 Test configuration
Only a single configuration of the TOE is available. The configuration of the samples 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.
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 1 site certificate and 19 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 SLM10TLD002Y design step A12 with
CALYPSO™ move software.
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 SLM10TLD002Y design step
A12 with CALYPSO™ move software, to be CC Part 2 extended, CC Part 3 extended, and to meet
the requirements of EAL 2 augmented with ALC_DVS.1 and AVA_SPECIFIC.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].

2.10 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:
o Calypso Crypto
o Calypso Basic protocol.
