1 Scope
The present document provides parts of the Abstract Test Suite (ATS) for ITS PKI management as defined in ETSI
TS 102 941 [2] in accordance with the relevant guidance given in ISO/IEC 9646-7 [i.6]. 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 standards for the methodology of conformance testing (ISO/IEC 9646-1 [i.3] and ISO/IEC 9646-2 [i.4]) as
well as the ETSI rules for conformance testing (ETSI ETS 300 406 [i.7]) 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 https://forge.etsi.org/gitlab/ITS/ITS/tags/TS103525-3_v1.1.1.
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-Pki framework.
5.2 Abstract protocol tester
The abstract protocol tester used by the ITS-Pki test suite is described in figure 1. The Test System simulates valid and
invalid protocol behaviour and analyses the reaction of the IUT.

Figure 1: Abstract protocol tester - Pki
5.3 Test Configuration
5.3.1 Introduction
This test suite shall use test configurations as defined in ETSI TS 103 525-2 [5], i.e. the tester simulates the AA
implementing the ITS Pki framework over HTTP 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 shall be as specified in ETSI TS 102 940 [1] and ETSI
TS 102 941 [2].
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 CA certificates
used by the Test System and by the IUT to verify the Test System certificates. For the generation procedure
see clause 5.3.2.5. 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_EA and CERT_IUT_AA) 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 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.
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 the 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 and private keys shall be stored as hexadecimal streams.
The TS selects certificate using its file name. Table 1 describes file extensions to be used to store certificates and private
keys.
Table 1: PKI file extensions
File extension File role
.crt Certificate
.vkey Verification private key
.ekey Encryption private key

Each Authorization Authority certificate contains:
• Start and End time
• Assurance level
• Permissions (AID list)
• Geographical Validity Restriction
Each Authorization Ticket certificate contains:
• Start and End time
• Assurance level
• Permissions (AID SSP list)
• Geographical Validity Restriction
