1 Scope
The present document provides parts of the Abstract Test Suite (ATS) for Security as defined in ETSI TS 103 097 [1] in
accordance with the relevant guidance given in ISO/IEC 9646-7 [10]. The objective of the present document is to provide a
basis for conformance tests for security communication over GeoNetworking equipment giving a high probability of interoperability
between different manufacturers' equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [7] and ISO/IEC 9646-2 [8]) as well as
the ETSI rules for conformance testing (ETSI ETS 300 406 [11]) are used as a basis for the test methodology.

4 Contents of the ITS Security Test Suite
The ITS Security test suite contains:
• test implemented in TTCN-3 code
• certificate profiles and certificate generation tool
To execute the ITS Security Test Suite a Test Adapter implementation and a TTCN-3 compiler is required. The
reference Test Adapter implementation can be found at http://forge.etsi.org. TTCN-3 compilers can be acquired at
http://www.ttcn-3.org.
5 Abstract Test Method
5.1 Introduction
This clause describes the ATM used to test the ITS-Security framework.
5.2 Abstract protocol tester
The abstract protocol tester used by the ITS-Security test suite is described in figure 1. The Test System simulates valid
and invalid protocol behaviour, and analyses the reaction of the IUT.

5.3 Test Configuration
5.3.1 Introduction
This test suite uses test configurations defined in ETSI TS 102 871-3 [3], i.e. the tester simulates the ITS station
implementing the ITS Security framework over GeoNetworking protocol.
5.3.2 PKI infrastructure
5.3.2.1 Overview
Before executing tests:
• security certificates need to be generated, see clause 5.3.2.5;
• security certificates need to be installed onto the IUT, see clause 5.3.2.6;
• and some Test System settings need to be configured, see clause 5.3.2.3.
5.3.2.2 PKI certificate hierarchy
The required PKI certificate hierarchy of the test infrastructure is presented in figure 2.

Figure 2: Required PKI certificate hierarchy
The following certificates are required for the test execution:
1) The custom user-generated root certificate, referred as CERT_TEST_ROOT, is used to sign all AA certificates
used by the Test System and by the IUT to verify the Test System certificates. For the generation procedure
see clause 7.1.4. The IUT shall install this CERT_TEST_ROOT certificate and consider it as trusted. In the
case where the IUT cannot install the CERT_TEST_ROOT, no tests can be executed.
2) Further certificates to be installed on the IUT:
- Option 1: Certificates (CERT_TS_AA and the set of CERT_IUT_AT) can be installed onto the IUT.
Please refer to clause 5.3.2.6 for further details on certificate installation.
If the IUT supports certificate selection using the UtInitialize Upper Tester command, than all mandatory
tests can be executed and PICS_CERTIFICATE_SELECTION shall be set to true.
- Option 2: The IUT can only use its own pre-installed certificates. In this case only a subset of mandatory
tests can be executed and PICS_CERTIFICATE_SELECTION shall be set to false.
In both cases it is necessary to copy these certificates or just their digests to the subfolder of the location defined in
PX_CERTIFICATE_POOL_PATH. The name of the subfolder shall be provided in
PX_IUT_SEC_CONFIG_NAME. Certificate digests can be stored within a file; each file shall have the same name as
the corresponding certificate (CERT_IUT_x_AT) and the 'dgs' extension.
It is not necessary to install IUT_ROOT and AA certificates onto the Test System when IUT and TS are using different
PKIs. The TS trusts any root and AA certificate from IUT.
A set of certificates and private keys to be used on the Test System side to sign various messages and other Test System
certificates. These files are generated by the generation script (see clause 5.3.2.5).
All certificates, private keys and digest shall be stored as a hexadecimal streams.
The TS selects certificate using its file name. Table 1 describes file extensions to be used to store certificates, private
keys and digests.

5.3.2.3.2 Test Suite Parameters
Most of test parameters are the same as for GeoNetworking test suite and described in ETSI TS 102 871-3 [3].
