1 Scope
The present document provides the Test Suite Structure and Test Purposes (TSS & TP) for Security as defined in
ETSI TS 103 097 [1] in accordance with the relevant guidance given in ISO/IEC 9646-7 [i.6].
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.

5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP definition conventions
The TP definition is built according to ETSI EG 202 798 [i.1].
5.1.2 TP Identifier naming conventions
The identifier of the TP is built according to table 2.
Table 2: TP naming convention
Identifier TP_______
= root SEC
= target ITSS ITS-S data transfer
 AA ITS-S - AA authorization
 EA ITS-S - EA enrolment
= group SND Sending behaviour
 RCV Receiving behaviour
=sub- group MSG Generic messages
 CAM CAM testing
 DENM DENM testing
 CERT Certificate testing
= test purpose sequential number 01 to 99
= category BV Valid Behaviour tests
 BO Invalid Behaviour Tests

5.1.3 Rules for the behaviour description
The description of the TP is built according to ETSI EG 202 798 [i.1].

9 ETSI TS 103 096-2 V1.4.1 (2018-08)
ETSI TS 103 097 [1] does not use the finite state machine concept. As a consequence, the test purposes use a generic
"Initial State" that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, the IUT
shall be left in this "Initial State", when the test is completed.
Being in the "Initial State" refers to the starting point of the initial device configuration. There are no pending actions,
no instantiated buffers or variables, which could disturb the execution of a test.
5.1.4 Sources of TP definitions
All TPs have been specified according to ETSI TS 103 097 [1] and IEEE Std 1609.2™[2].
5.1.5 Mnemonics for PICS reference
To avoid an update of all TPs when the PICS document is changed, table 3 introduces mnemonics name and the
correspondence with the real PICS item number. The 'PICS item' as defined in IEEE Std 1609.2 [2], ETSI
TS 103 096-1 [3] and ETSI TS 102 871-1 [4] shall be used to determine the test applicability.
