Certification Report BSI-DSZ-CC-1069-2018
A. Certification
1. Preliminary Remarks
Under the BSIG1 Act, the Federal Office for Information Security (BSI) has the task of
issuing certificates for information technology products.
Certification of a product is carried out on the instigation of the vendor or a distributor,
hereinafter called the sponsor.
A part of the procedure is the technical examination (evaluation) of the product according
to the security criteria published by the BSI or generally recognised security criteria.
The evaluation is normally carried out by an evaluation facility recognised by the BSI or by
BSI itself.
The result of the certification procedure is the present Certification Report. This report
contains among others the certificate (summarised assessment) and the detailed
Certification Results.
The Certification Results contain the technical description of the security functionality of
the certified product, the details of the evaluation (strength and weaknesses) and
instructions for the user.
2. Specifications of the Certification Procedure
The certification body conducts the procedure according to the criteria laid down in the
following:
● Act on the Federal Office for Information Security1
● BSI Certification and Approval Ordinance2
● BSI Schedule of Costs3

3. Recognition Agreements
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or
CC - under certain conditions was agreed.
3.1. European Recognition of CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in
April 2010. It defines the recognition of certificates for IT-Products at a basic recognition
level and, in addition, at higher recognition levels for IT-Products related to certain SOGIS
Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels
EAL 1 to EAL 4. For "Smartcards and similar devices" a SOGIS Technical Domain is in
place. For "HW Devices with Security Boxes" a SOGIS Technical Domains is in place, too.
In addition, certificates issued for Protection Profiles based on Common Criteria are part of
the recognition agreement.
The current list of signatory nations and approved certification schemes, details on
recognition, and the history of the agreement can be seen on the website at
https://www.sogisportal.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the
terms of this agreement by the related bodies of the signatory nations. A disclaimer
beneath the logo indicates the specific scope of recognition.
This certificate is recognized under SOGIS-MRA for all assurance components selected.
3.2. International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC
(Common Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08
September 2014. It covers CC certificates based on collaborative Protection Profiles (cPP)
(exact use), CC certificates based on assurance components up to and including EAL 2 or
the assurance family Flaw Remediation (ALC_FLR) and CC certificates for Protection
Profiles and for collaborative Protection Profiles (cPP).
The current list of signatory nations and approved certification schemes can be seen on
the website: https://www.commoncriteriaportal.org.
The Common Criteria Recognition Arrangement logo printed on the certificate indicates
that this certification is recognised under the terms of this agreement by the related bodies
of the signatory nations. A disclaimer beneath the logo indicates the specific scope of
recognition.

Certification Report BSI-DSZ-CC-1069-2018
This certificate is recognized according to the rules of CCRA-2014, i. e. up to and including
CC part 3 EAL 2+ ALC_FLR components.
4. Performance of Evaluation and Certification
The certification body monitors each individual evaluation to ensure a uniform procedure, a
uniform interpretation of the criteria and uniform ratings.
The product Digital Tachograph DTCO 1381, Release 4.0 has undergone the certification
procedure at BSI. This is a re-certification based on BSI-DSZ-CC-1015-2017. Specific
results from the evaluation process BSI-DSZ-CC-1015-2017 were re-used.
The evaluation of the product Digital Tachograph DTCO 1381, Release 4.0 was conducted
by T-Systems International GmbH. The evaluation was completed on 22 November 2018.
T-Systems International GmbH is an evaluation facility (ITSEF)5
recognised by the
certification body of BSI.
For this certification procedure the sponsor and applicant is: Continental Automotive
GmbH.
The product was developed by: Continental Automotive GmbH.
The certification is concluded with the comparability check and the production of this
Certification Report. This work was completed by the BSI.
5. Validity of the Certification Result
This Certification Report applies only to the version of the product as indicated. The
confirmed assurance package is valid on the condition that
● all stipulations regarding generation, configuration and operation, as given in the
following report, are observed,
● the product is operated in the environment described, 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
itself. Detailed references are listed in part C of this report.
The Certificate issued confirms the assurance of the product claimed in the Security Target
at the date of certification. 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 sponsor should apply for the certified product being monitored within the
assurance continuity program of the BSI Certification Scheme (e.g. by a re-assessment or
re-certification). Specifically, if results of the certification are 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 avoid an indefinite usage of the certificate when evolved attack methods would
require a re-assessment of the products resistance to state of the art attack methods, the
maximum validity of the certificate has been limited. The certificate issued on 6 December
2018 is valid until 5 December 2023. Validity can be re-newed by re-certification.
The owner of the certificate is obliged:

1. Executive Summary
The Target of Evaluation (TOE) is the Digital Tachograph DTCO 1381 Rel. 4.0. It is a
second generation vehicle unit (VU) in the sense of Annex IC [9] intended to be installed in
road transport vehicles. Its purpose is to record, store, display, print and output data
related to driver activities. It is connected to a motion sensor with which it exchanges
vehicle’s motion data.
The VU records and stores human user activities data in its internal data memory, it also
records human user activities data in tachograph cards. The VU outputs data to display,
printer and external devices.
The TOE is connected to a motion sensor with which it obtains the vehicle’s motion data.
Information from the motion sensor is corroborated by vehicle motion information derived
from a GNSS receiver.
The TOE may be connected to an external remote early detection facility (a DSRC
communication module), to allow remote early detection equipment to detect possible
manipulation or misuse of the VU.
The Security Target [6] is the basis for this certification. It is based on the certified
Protection Profile Digital Tachograph - Vehicle Unit (VU PP) Version 1.0, 9 May 2017, BSI-
CC-PP-0094-2017 [8].
The TOE Security Assurance Requirements (SAR) are based entirely on the assurance
components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details).
The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 4
augmented by ATE_DPT.2 and AVA_VAN.5.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6], chapter 6. They are selected from Common Criteria Part 2 and some of
them are newly defined. Thus the TOE is CC Part 2 extended.
The TOE Security Functional Requirements are implemented by the following TOE

BSI-DSZ-CC-1069-2018 Certification Report
The TOE delivery to the customer is carried out in sealed boxes. The delivery will be
announce by a shipping note electronically. The activation and calibration of the TOE at
the customer requires an authorisation with a workshop tachograph card and PIN.
Self-collectors can get the TOE only from workshops who are authorised for TOE
calibration.
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:
● Data is recorded and stored in such a way as to prevent unauthorized access to and
manipulation of the data and detecting any such attempts
● Integrity and authenticity of data exchanged between the motion sensor and the vehicle
unit
● Integrity and authenticity of data exchanged between the recording equipment and the
tachograph cards
● Integrity and authenticity of data downloaded (locally and remotely)
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 aspects lead to
specific security objectives to be fulfilled by the TOE-Environment. Details can be found in
the Security Target [6], chapter 4.2.
5. Architectural Information
The TOE consists of a hardware box including the following subsystems:
● processing unit,
● data memory,
● real time clock,
● two smart card interface devices for driver and co-driver,
● printer,
● display,
● visual warning system,
● facilities for entry of human user's inputs
● embedded software
6. Documentation
The evaluated documentation as outlined in table 2 is being provided with the product to
the customer. This documentation contains the required information for secure usage of
the TOE in accordance with the Security Target.
13 / 22
Certification Report BSI-DSZ-CC-1069-2018
Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of
this report have to be followed.
7. IT Product Testing
Developer tests:
All properties/characteristics of the TSFI as described in the functional specification, the
TSF subsystem behaviour and the interaction among TSF subsystems as described in the
design documentation, and all interfaces to the SFR-enforcing modules have been tested
by the developer. The TOE responded to the tests as expected.
Evaluator tests:
The evaluators spent adequate testing effort for the desired resistance of the TOE against
attackers with a high attack potential. The evaluators spent several days each for
analysing the test specification and ensuring that the specification has been correctly
implemented in the test scripts,
● for creating ideas for independent evaluator tests,
● for ensuring that the test environment delivers correct test results, and
● for repeating developer tests as well as carrying out independent tests.
TOE test configurations:
For the penetration testing the TOE was tested in its operative state. Modifications of the
devices were performed before the TOE was brought into its operative state in order to
suppress warnings. The later tests were performed in the operative state of the TOE.
Independent tests:
Independent tests were identified based on the developer tests already available. The
developer tests have been compared with the ST, the FSP and the TDS in order to
determine the fields of further investigation. Furthermore the evaluator devised tests based
on a systematically analysis of the ST.
The evaluators conducted independent testing at the developer's site.
The evaluator tests have been carried out against the following TOE configurations: The
TOE was brought in every production control state. A simulator for the motion sensor was
used. Furthermore every card type (Driver card, workshop card, control card, and
company card) was used. For the company card also the remote authentication was in the
focus of the tests.
According to EAL4, functional testing is performed down to the depth of SFR-enforcing
module interfaces.
The tests showed that the TOE behaves as expected in all configurations that are
considered as part of the evaluation. No deviation was found between the expected and
the actual test results. The depth of testing is adequate for the evaluation assurance level
chosen (EAL4+). The TOE has successfully passed independent testing.
The evaluator reports the evaluator penetration testing effort, outlining the testing
approach, configuration, depth and results.
Penetration tests:
The penetration testing was performed using the developer’s testing environment.
14 / 22
BSI-DSZ-CC-1069-2018 Certification Report
All configurations of the TOE being intended to be covered by the current evaluation were
tested.
On the basis of the methodical vulnerability analysis some potential vulnerabilities have
been identified by the evaluator. These potential vulnerabilities have been analysed, if they
are exploitable in the planned operational environment. For every potential vulnerability
which was identified to be a candidate to be exploitable in the planned operational
environment the evaluator devised and conducted penetration tests.
The overall test result is that no deviations were found between the expected and the
actual test results. No attack scenario with the attack potential High was actually
successful in the TOE’s operational environment as defined in [6] provided that all
measures required by the developer are applied.
8. Evaluated Configuration
This certification covers the following configurations of the TOE:
The TOE Digital Tachograph DTCO 1381 Release 4.0 is an electronic device, consisting of
hardware and software, and additionally of documentations (see table 2). The TOE was
tested with the following software versions:
● Tachograph Applikation Version 04.00.42
● Software Update Module Version 04.05.
There is only one configuration of the vehicle unit that is delivered to the approved
workshops. The configurations at delivery, as well as the further steps to be taken in order
to activate and calibrate the TOE in a vehicle are described in [14]. The correct input of the
calibration parameters is guaranteed by the trustworthiness of the accredited work shops
(see [6] A.Approved_Workshops).
9. Results of the Evaluation
9.1. CC specific results
The Evaluation Technical Report (ETR) [7] was provided by the ITSEF according to the
Common Criteria [1], the Methodology [2], the requirements of the Scheme [3] and all
interpretations and guidelines of the Scheme (AIS) [4] as relevant for the TOE.
The Evaluation Methodology CEM [2] was used for those components up to EAL 5
extended by advice of the Certification Body for components beyond EAL 5 and guidance
specific for the technology of the product [4] (AIS 34).
The following guidance specific for the technology was used:
● The Application of CC to Integrated Circuits
● The Application of Attack Potential to Smartcards
(see [4], AIS 25, AIS 26, AIS 32, AIS 34, AIS 36) were used.
For RNG assessment the scheme interpretations AIS 20 was used (see [4]).
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 4 package including the class ASE as defined in the CC (see
also part C of this report)
15 / 22
Certification Report BSI-DSZ-CC-1069-2018
● The components ATE_DPT.2 and AVA_VAN.5 augmented for this TOE evaluation.
As the evaluation work performed for this certification procedure was carried out as a re-
evaluation based on the certificate BSI-DSZ-CC-1015-2017, re-use of specific evaluation
tasks was possible.
The evaluation has confirmed:
● PP Conformance: Digital Tachograph - Vehicle Unit (VU PP) Version 1.0,
9 May 2017, BSI-CC-PP-0094-2017 [8]
● for the Functionality: PP conformant
Common Criteria Part 2 extended
● for the Assurance: Common Criteria Part 3 conformant
EAL 4 augmented by ATE_DPT.2 and AVA_VAN.5
For specific evaluation results regarding the development and production environment see
annex B in part D of this report.
The results of the evaluation are only applicable to the TOE as defined in chapter 2 and
the configuration as outlined in chapter 8 above.
9.2. Results of cryptographic assessment
The table presented in chapter 12 of the Security Target [6] 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 the these cryptographic algorithms was not rated in the course of this
certification procedure (see BSIG Section 9, Para. 4, Clause 2).
10. Obligations and Notes for the Usage of the TOE
The documents as outlined in table 2 contain necessary information about the usage of the
TOE and all security hints therein have to be considered. In addition all aspects of
Assumptions, Threats and OSPs 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 of the
TOE is required and thus requested from the sponsor of the certificate.
The limited validity for the usage of cryptographic algorithms as outlined in chapter 9 has
to be considered by the user and his system risk management process, too.
If available, certified updates of the TOE should be used. If non-certified updates or
patches are available the user of the TOE should request the sponsor to provide a re-
certification. In the meantime a risk management process of the system using the TOE
should investigate and decide on the usage of not yet certified updates and patches or
take additional measures in order to maintain system security.
11. Security Target
