A. Certification
1. Preliminary Remarks
The Implementing Regulation (EU) 2024/482 of the European Parliament and of the
Council of 31 January 2024 [EUCC-VO] establishes a Union-wide cybersecurity
certification scheme for TOEs and Protection Profiles for conformity assessments using
the requirements of Common Criteria.
By implementing the Cybersecurity Act1
, certification activities at assurance level ‘high’ and
in duly justified cases at assurance level ‘substantial’ are reserved to the National
Cybersecurity Certification Agency of a Member State.
In accordance to BSIG2
Act, the Federal Office for Information Security (BSI) issues
certificates for information technology products.
Certification of a product is carried out at the request of a developer, vendor or a
distributor, hereinafter called the applicant.
A part of the procedure is the technical examination (evaluation) of the product according
to the security criteria referenced in the above mentioned Implementing Regulation (EU)
2024/482 as well as relevant application notes and interpretations published by the
certification body of the BSI.
Evaluation facilities notified by the German National Cybersecurity Certification Authority
carry out the evaluation.
This Certification Report is the result of the certification activities carried out by the
certification body of the BSI in conclusion of the technical evaluation. This report contains
among others the certificate (summarised assessment) and the detailed Certification
Results.

● The TOE TCOS FlexCert Version 2.0 Release 2/SLC52 has been previously certified by
the certification body of the Federal Office for Information Security (BSI) based on
administration ID BSI-DSZ-CC-0904-V2-2021 (including subsequent maintenance
procedure). Specific results from the corresponding evaluation process were re-used.
● The present evaluation of the product TCOS FlexCert Version 2.0 Release 2/SLC52 was
carried out by SRC Security Research & Consulting GmbH, located at Emil-Nolde-
Straße 7, 53113 Bonn, Germany.
● The evaluation was completed on 19 June 2026. SRC Security Research & Consulting
GmbH is a notified evaluation facility (ITSEF).
● This certification was applied for: Deutsche Telekom Security GmbH.
● The assessed TOE was developed by: Deutsche Telekom Security GmbH.
● The certification activities are concluded with the comparability check and the production
of this Certification Report. This work was completed by the certification body of the BSI.
This Certification Report applies only to the version of the TOE as identified in this
document. The confirmed assurance package is valid on the condition that
● all statements and indications regarding generation, configuration and operation, as
given in the following report, are observed,
● the product is operated in an environment as specified in the following report and in the
Security Target.
For the meaning of the assurance components and assurance levels please refer to CC
[CC] itself.
The issued Certificate confirms the assurance of the product claimed in the Security Target
[ST] on certificate’s issuance day. As attack methods evolve over time, the resistance of
the certified version of the product against new attack methods needs to be re-assessed.
Therefore, the holder of the Certificate should involve the assurance continuity program of
the EUCC Certification Scheme (e.g. by a re-assessment or re-certification) in its
obligations to monitor the certified product. Specifically, if certification results should be
used in subsequent evaluation and certification procedures, in a system integration
process or if a user's risk management needs regularly updated results, it is recommended
to perform a re-assessment on a regular e.g. annual basis.
In order to prevent an indefinite certificate usage where evolving attack methods justify a
recent re-assessment of the product’s resistance, the maximum validity period of the
certificate is limited. The certificate issued on 3 July 2026 is valid until 2 July 2031 and its
validity can be renewed by certifying the TOE again.
The holder of this certificate is obliged:
● to meet the obligations from the Implementing Regulation (EU) 2024/482, in particular
but not exclusively to respect the rules for certificate usage, to monitor the conformity of
the certified TOE, to inform the certification body about subsequently detected
vulnerabilities or irregularities with relevance to the security of the TOE and to maintain
vulnerability management and disclosure procedures.
Should changes be introduced into the certified version of the TOE, the validity period of its
related certificate can be extended in order to cover the changed TOE, provided the holder
of the certificate applies for measures under EUCC scheme’s assurance continuity (i.e. re-
certification or maintenance) and the changed TOE then meets the assurance
requirements.

1. Executive Summary
The Target of Evaluation (TOE) is the product TCOS FlexCert Version 2.0 Release
2/SLC52 developed by Deutsche Telekom Security GmbH.
The TOE is a smart card product according to the G2-COS specification [Spec G2 COS]
from gematik and is implemented on the hardware platform Infineon Security Controller
IFX_CCI_000010h (SLC52GDA600A8 / SLC52GDA600A9) from Infineon Technologies
AG (refer to [ST IC], [CertRep IC]).
The TOE is intended to be used as a card operating system platform for cards of the card
generation G2 in the framework of the German health care system.
For this purpose, the TOE serves as secure data storage and secure cryptographic service
provider for card applications running on the TOE and supports them for their specific
security needs related to storage and cryptographic functionalities. In particular, these
storage and cryptographic services are oriented on the different card types eHC (electronic
Health Card), HPC (Health Professional Card), SMC-B (Security Module Card Type B),
gSMC-K (gerätespezifische Security Module Card Type K for the so-called Konnektor) and
gSMC-KT (gerätespezifische Security Module Card Type KT for Terminals) as currently
specified for a card product of the generation G2 within the German health care system.
These TOE's storage and cryptographic services that are provided by the TOE and
invoked by the human users and components of the German health care system cover the
following issues:
• authentication of human users and external devices,
• storage of and access control on user data,
• key management and cryptographic functions,
• management of TSF data including life cycle support,
• export of non-sensitive TSF and user data of the object system if implemented.
The TOE comprises
• the circuitry of the dual-interface chip (i.e. contact-based and contactless chip)
including all IC Dedicated Software being active in the Smart Card Initialisation
Phase, Personalisation Phase and Usage Phase of the TOE (the integrated circuit,
IC Infineon IFX_CCI_000010h (SLC52GDA600A8 / SLC52GDA600A9)),
• the IC Embedded Software (TCOS FlexCert Version 2.0 Release 2/SLC52
Operating System),
• the so-called Wrapper (TOE specific SW tool for re-coding and interpretation of
exported TSF and user data), and
• the associated guidance documentation.
The TOE is ready for the installation and personalisation of object systems (applications)
on the TOE that match the G2-COS specification [Spec G2 COS], but does not contain
itself any object systems (applications). However, the delivered product comprises beside
the TOE also an object system already installed on the TOE.
In functional view, the TOE with its IC Embedded Software (TCOS FlexCert Version 2.0
Release 2/SLC52 Operating System) is implemented according to the G2-COS
specification [Spec G2 COS] from gematik. Hereby, the TOE implements the mandatory
part of the G2-COS specification [Spec G2 COS] with the base functionality of the
9 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
operating system platform. In addition, the TOE implements the option RSA Key
Generation (“Option_RSA_KeyGeneration”), the option Contactless
(“Option_kontaktlose_Schnittstelle”), the option Crypto Box (“Option_Kryptobox”) and the
option Logical Channel (“Option_logische_Kanäle“) as defined in the G2-COS specification
[Spec G2 COS]. None of the further options PACE for Proximity Coupling Device
(“Option_PACE_PCD”), USB (“Option_USB_Schnittstelle”) and RSA CVC
(“Option_RSA_CVC”) defined in the G2-COS specification [Spec G2 COS] is implemented
in the TOE.
Furthermore, the TOE provides developer-specific administration commands for support of
the TOE’s life cycle model (refer to the user guidance [Guide ADM], chapter 6 and [Guide
OPE P2], chapter 4).
The TOE's Wrapper is implemented according to the Wrapper specification [Spec
Wrapper] from gematik.
The product TCOS FlexCert Version 2.0 Release 2/SLC52 has been certified under the

Phase 4: IC packaging and testing
12 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
Phase 5: Smartcard product finishing process
Phase 6: Smartcard personalization (including object system installation and
personalisation)
Phase 7: Smartcard end-usage
The finalised TOE is a chip with completed IC Embedded Software and may be of type
module or smart card depending on the chosen production variant. Hereby, the TOE
delivery in the sense of the CC takes place at the end of Phase 5 after completion of the
IC Embedded Software by the COS-Installation Agent so that the evaluation process is
limited to Phases 1 to 5 up to the finalisation of the completion process in Phase 5.
Independent of the different production variants and TOE form factor the TOE is delivered
by Deutsche Telekom Security GmbH at the end of Phase 5 to the OS-Initialization Agent
(acting in Phase 6) as already embedded smart card.
In order to verify that the user uses a certified TOE, the TOE can be identified using the
means described in the user guidance [Guide ADM], chapter 6.1.1.1 and [Guide OPE P2],
chapter 7.7. The TOE can be identified by using the command FORMAT (only in Phase 6
of the TOE's life cycle model) respective the command GET CARD INFO (in Phases 6 and
7 of the TOE's life cycle model). Via the command FORMAT (CLA = ‘B0’, INS = ‘50’ with
P1 = '00' and P2 = '00') respective the command GET CARD INFO (CLA = '80', INS = 'AA'
with P1 = '06' and P2 = '00') the user can read out the chip information and identify the
underlying chip as well as the TCOS FlexCert Version 2.0 Release 2/SLC52 Operating
System (including completion data) installed in the chip. In order to open the
Personalization Phase for object system installation and personalisation of the installed
object system (Phase 6 of the TOE's life cycle model) a mutual authentication via the
command FORMAT as described in the user guidances [Guide ADM], chapter 6.1.1.4 and
[Guide OPE P2], chapter 4.1.4 is necessary, therefore the authenticity of the TOE is
verified before further usage of the TOE.
The following identification data can be retrieved within a 16 Byte string responded by the
commands FORMAT respective GET CARD INFO:
Byte Product information Value
1 Indicator of the chip manufacturer according to ISO 7816-6 '05'
2 Chip Type (Type ID of the chip manufacturer) '22'

Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
Note that Bytes 3 – 8 (Unique identification number for the chip) are chip specific data
which differ for each chip used in the TOE. Byte 16 (Authentication key identifier) is
customer specific data and differs for each different authentication key. The authentication
key can also be changed by the installation or personalisation agent, which results in
changing the authentication key identifier as well. Therefore, the unique identification
number for the chip and the authentication key identifier are not specified in the table
above.
3. Security Policy
The Security Policy is expressed by the set of Security Functional Requirements and
implemented by the TOE. It covers the following issues:
• authentication of human users and external devices,
• storage of and access control on user data,
• key management and cryptographic functions,
• management of TSF data including life cycle support,
• export of non-sensitive TSF and user data of the object system if implemented.
The TOE is intended to be used as a card operating system platform for applications of the
card generation G2 in the framework of the German health care system. For this purpose,
the TOE serves as secure data storage and secure cryptographic service provider for card
applications running on the TOE and supports them for their specific security needs related
to storage and cryptographic functionalities. In particular, these storage and cryptographic
services are oriented on the different card types eHC (electronic Health Card), HPC
(Health Professional Card), SMC-B (Security Module Card Type B), gSMC-K
(gerätespezifische Security Module Card Type K for the so-called Konnektor) and gSMC-
KT (gerätespezifische Security Module Card Type KT for Terminals) as currently specified
for a card product of the generation G2 within the German health care system.
The TOE implements physical and logical security functionality in order to protect user
data and TSF data stored and operated on the smart card when used in a hostile
environment. Hence the TOE maintains integrity and confidentiality of code and data
stored in its memories and the different CPU modes with the related capabilities for
configuration and memory access and for integrity, the correct operation and the
confidentiality of security functionality provided by the TOE. Therefore the TOE's overall
policy is to protect against malfunction, leakage, physical manipulation and probing.
Besides, the TOE's life cycle is supported as well as the user Identification whereas the
abuse of functionality is prevented. Furthermore, specific cryptographic services including
random number generation and key management functionality are being provided to be
securely used by the smart card embedded software.
Specific details concerning the above mentioned security policies can be found in the
Security Target [ST], chapter 6.
4. Assumptions and Clarification of Scope
The assumptions defined in the Security Target and some aspects of threats and
organisational security policies are not covered by the TOE itself. These uncovered
aspects need to be provided by specific security objectives that have to be met by the TOE
environment. The following topics are of relevance:

Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
Please refer to chapter 1 of this report for details on assurance levels or packages
involved into testing.
For the state-of-the-art documents and supporting documents applied please refer to
chapter 9.1 of this report.
The developer tested all TOE Security Functions either on real cards or with simulator
tests. For all commands and functionality tests, test cases are specified in order to
demonstrate its expected behaviour including error cases. Hereby a representative sample
of possible parameters including all boundary values of the parameter set was tested, e.g.
all command APDUs with valid and invalid inputs were tested and all functions were tested
with valid and invalid inputs. Repetition of developer tests was performed during the
independent evaluator tests.
Since many Security Functions can be tested by APDU command sequences, the
evaluators performed these tests with real cards. This is considered to be a reasonable
approach because the developer tests include a full coverage of all security functionality.
Furthermore penetration tests were chosen by the evaluators for those Security Functions
where internal secrets of the card could maybe be modified or observed during testing.
During their independent testing, the evaluators covered:
• testing APDU commands related to Key Management and Crypto Functions,
• testing APDU commands related to NVM Management and File System,
• testing APDU commands related to Security Management,
• testing APDU commands related to Secure Messaging,
• testing APDU commands related to the PACE-protocol,
• penetration testing related to the verification of the reliability of the TOE,
• source code analysis performed by the evaluators,
• side channel analysis including machine learning methods for SHA, RSA and ECC,
including RSA and ECC key generation,
• fault injection attacks (laser and EM attacks),
• testing APDU commands for the object system installation / personalisation and
usage phase,
• testing APDU commands for the commands using cryptographic mechanisms,
• fuzzy testing on APDU processing.
The evaluators have tested the TOE systematically against high attack potential during
their penetration testing.
The achieved test results correspond to the expected test results.
Please refer to chapter 8 for complete and precise information on settings and
configuration of the TOE during the evaluation, including relevant operational notes and
observations.

The results of the evaluation are only applicable to the TOE as defined in chapter 1 and 2
and the configuration as outlined in chapter 8 above.
9.2. Results of cryptographic assessment
The table in annex C of part C of this report gives an overview of the cryptographic
functionalities inside the TOE to enforce the security policy and outlines the standard of
application where its specific appropriateness is stated.
The strength of these cryptographic algorithms was not rated in the course of this
certification procedure (see BSIG Section 52, Para. 4, Clause 2).
According to the specification [Spec G2 COS] and the Technical Guideline BSI TR-03116-1
[TR-03116-1] the algorithms are suitable for authentication and key agreement and for
supporting integrity, authenticity and confidentiality of the data stored in and processed by
the TOE as a card operating system platform that is intended to be used for cards of the
card generation G2 (in particular of type eHC (electronic Health Card), HPC (Health
Professional Card), SMC-B (Security Module Card Type B), gSMC-K (gerätespezifische
Security Module Card Type K for the so-called Konnektor) and gSMC-KT
(gerätespezifische Security Module Card Type KT for Terminals)) in the framework of the
19 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
German health care system. An explicit validity period of each algorithm is not provided
here.
10. Obligations and Notes for the Usage of the TOE
Table 1 outlines the documents that contain necessary information on the intended use of
the TOE including all security related information, conditions and instructions to be taken
into account by the user. In addition, all aspects of Assumptions, Threats and OSPs as
outlined in the Security Target and not covered by the TOE itself need to be met by the
operational environment of the TOE.
The customer or user of the TOE shall take the statements of this certificate into account in
its system risk management process. The user should define measures in its risk
management that respond to emerging and new attack methods and techniques to the
TOE until the TOE has been re-assessed.
The user also has to consider in its risk management the limited validity for the usage of
cryptographic algorithms as outlined in chapter 9.
Some security measures are partly implemented in this certified TOE, but require
additional configuration or control or measures to be implemented by a product layer on
top, e.g. the Application Software using the TOE. For this reason the TOE includes
guidance documentation (see table 1) which contains obligations and guidelines for the
developer of the product layer on top on how to securely use this certified TOE and which
measures have to be implemented in order to fulfil the security requirements of the
Security Target of the TOE. In the course of the evaluation of the composite product or
system it must be examined if the required measures have been correctly and effectively
implemented by the product layer on top.
In particular, the following aspects from the TOE user guidance documentation need to be
taken into account when using the TOE and when designing and implementing object
systems (applications) intended to be set up on the TOE, especially in view of later TR-
conformity testing of card products according to the Technical Guideline BSI TR-03144
([TR-03144]):
• Security requirements and hints for designing and implementing object systems
(applications) intended to be set up and running on the TOE:
This concerns on the one hand the design and generation of production files
containing such object system by the developer. As well this concerns on the other
hand after TOE delivery the application developers and card management e.g. by
using the command LOAD APPLICATION.
The TOE implements a specific access rule concept, in particular concerning the
default settings for access rules by the TOE itself and the flexibility to define
customer-specific access rules. Refer to the user guidances [Guide OPE P2],
Annex A and [Guide WRAP], chapter 2.2.
For an object system, one has to take care of the choice of the access rules for the
object system's objects. In particular, this concerns key and PIN objects including
their related files for the key and PIN data and assigned security attributes.
For the choice of the access rules for the object system's objects one has to
consider that the TOE's Wrapper is only able to export security attributes and public
key data of the object system and its objects if their access rules are set
appropriately for read access.
20 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
For card products that undergo a later TR-conformity testing according to the
Technical Guideline BSI TR-03144 ([TR-03144]) it is strongly recommended to care
for the appropriate choice of the access rules for all object system's objects. It shall
be possible for the Konsistenz-Prüftool according to the Technical Guideline BSI
TR-03143 ([TR-03143]) that is used for conformity testing to get a complete picture
of the object system installed in the card product for further comparison against the
respective object system specification.
The specific life cycle state concept of the TOE for objects managed and processed
by the TOE as the MF, folders, files, key and PIN objects has to be taken into
account. Especially, the concept of physical and logical life cycle states, their
specific processing by the TOE and their handling in combination with the TOE's
specific access rule concept (see above) are of relevance for object systems
intended to run on the TOE.
Any object system set up on the TOE shall only make use of the TOE's functionality
as described in the G2-COS specification [Spec G2 COS] and the user guidance
[Guide ADM], [Guide OPE P1] and [Guide OPE P2]. The object system has to be
checked for taking this requirement into account by using the TOE's Wrapper and
carrying out further manual checks in order to get information about functionality
that lies beyond the certified TOE scope, but is used in the card product. In
particular, this means looking for exceptions thrown by the Wrapper as well as
looking for information provided via the Wrapper that indicates the use of
proprietary (uncertified) COS functionality in the card product. Card products with
an object system that do not fulfil the requirement run out of the scope of the
certified TOE and shall not be delivered respective used. Refer in particular to the
user guidance [Guide OPE P2], chapter 10.5.
• Security requirements and hints for Phase 5 (concerning the antenna production),
Phase 6 (concerning the installation and personalisation of object systems on the
TOE by the OS-Initialization Agent respective Personalisation Agent) and for Phase
7 (for end-usage) of the TOE's life cycle model:
Refer to the user guidances [Guide MOD], [Guide ADM], in particular chapter 5 and
7, [Guide OPE P2], chapter 10.5.
• The TOE's Wrapper and its specifics beyond the Wrapper specification [Spec
Wrapper], in particular concerning manufacturer specific attributes exported by the
Wrapper:
Refer to the user guidance [Guide WRAP].
• For security instructions related to the secure use of the TOE:
Refer to the user guidance [Guide OPE P2], chapter 10. In particular, the following
aspects need to be taken into account:
Restrictions for key usage. Refer to the user guidance [Guide OPE P2], chapter
10.5.
Uniqueness of key identifier. Refer to the user guidance [Guide WRAP], chapter
2.1.
• For the design and generation of production files containing an object system for
card products that undergo a later TR-conformity testing according to the Technical
Guideline BSI TR-03144 ([TR-03143]) it is strongly recommended to care for that
via the card product's personalisation initialised security attributes and public key
21 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
data of the object system and its objects cannot be overwritten (except for where
explicitly intended by the object system's intention and design).
For a TR-conformity testing of a card product set up on the TOE according to the Technical
Guideline BSI TR-03144 ([TR-03144]) the following specific aspects and issues have to be
taken into account:
• The card product shall be checked that the export of the security attributes and
public key data of the object system and each of its objects via the TOE's Wrapper
is possible without any restriction and therefore fulfils the requirements for data
export in the Wrapper specification [Spec Wrapper]. This means that it has to be
ensured that there is no restriction for read access to all the related files in the
object system because of an inappropriate choice of the access rules. It shall be
possible for the Konsistenz-Prüftool according to the Technical Guideline BSI
TR-03143 ([TR-03143]) that is used for conformity testing to get a complete picture
of the object system installed in the card product for further comparison against the
respective object system specification. Refer to the user guidances [Guide OPE
P2], chapter 10.5 and Annex A, [Guide WRAP], chapter 2.2.
Note: If such export property cannot be checked in the card product or if read
access for the export of the security attributes and public key data of the object
system and each of its objects via the TOE's Wrapper is not given the card product
will be rejected for a TR-certificate according to the Technical Guideline BSI
TR-03144 ([TR-03144]).
• Any object system set up on the TOE shall only make use of the TOE's functionality
as described in the G2-COS specification [Spec G2 COS] and the user guidances
[Guide ADM], [Guide OPE P1] and [Guide OPE P2].
The card product's object system has to be manually checked for taking this
requirement into account by using the TOE's Wrapper and carrying out further
manual checks in order to get information about functionality that lies beyond the
certified TOE scope, but is used in the card product. In particular, this means
looking for exceptions thrown by the Wrapper as well as looking for information
provided via the Wrapper that indicates the use of proprietary (uncertified) COS
functionality in the card product.
Note: If there is any object found for which the TOE's Wrapper throws an exception
or where the Wrapper or Konsistenz-Prüftool according to the Technical Guideline
BSI TR-03143 ([TR-03143]) indicates the use of proprietary (uncertified) COS
functionality the card product will be rejected for a TR-certificate according to the
Technical Guideline BSI TR-03144 ([TR-03144]).
• For the card product, it has to be checked that via the card product's personalisation
initialised security attributes and public key data of the object system and its objects
cannot be overwritten (except for where explicitly intended by the object system's
intention and design).
Note: If overwriting of initialised security attributes and public key data of the object
system and its objects via the card product's personalisation is possible and not
technically suppressed (except for data where overwriting is explicitly intended by
the object system's intention and design) the card product will be rejected for a TR-
certificate according to the Technical Guideline BSI TR-03144 ([TR-03144]).
• If in the framework of the TR-conformity testing of a card product according to the
Technical Guideline BSI TR-03144 ([TR-03144]) the Konsistenz-Prüftool according
22 / 37
Certification Report
EUCC-3087-2026-0012 BSI-DSZ-CC-0904-V3-2026
to the Technical Guideline BSI TR-03143 ([TR-03143]) depicts in its test report
within an access rule of an object a wild card or an APDU header lying outside the
G2-COS specification [Spec G2 COS] or the user guidances [Guide ADM], [Guide
OPE P1] and [Guide OPE P2] this has to be manually examined and valuated.
• For card products that undergo a TR-conformity testing according to the Technical
Guideline BSI TR-03144 ([TR-03143]), the OS identification data retrieved via the
command FORMAT or GET CARD INFO shall be checked for correctness related to
the identification data described in chapter 2 of this Certification Report.
