mandatory requirements defined in clauses 4.1.2 and 4.1.3.
NOTE: Interoperability testing between two IUTs cover mandatory requirements and optional requirements
supported by the IUTs.

Mandatory requirements:
• The ITS-S shall support data communication using security mechanisms described in ETSI TS 103 759 [2].
• The ITS-S shall support algorithms and key length according to the Certificate Policy [3].
• In order to participate in misbehaviour reporting tests, the ITS-S shall be able to send CAMs and DENMs
using V2X communication.

In order to participate in the test with the present configurations, IUTs (participating entities) shall be configured as
follows:
• All participating ITS-Ss are in the "authorized" state (equipped with valid ATs).
• The AT of participating ITS-Ss allows the transmission of CAMs and DENMs in the time and place of UC

• All involved CA certificates shall be known and trusted by all participating ITS-S.
NOTE: Use-case definitions may contain additional configuration details.
4.2.2 CFG_LONG_RANGE communication
This clause describes the configuration used to execute misbehaviour reporting test scenarios. The configuration
contains the following entities:
• Actor - The virtual ITS-S producing the fault message or behaviour.
• Detector - The ITS-Sdetecting the misbehaviour and sending the MR using the long range communication
channel.
• Receiver MA - The Misbehaviour Authority receives MR from the Detector by the long range communication
channel.

4.2.3 CFG_SHORT_RANGE communication
This clause describes the configuration used to execute misbehaviour reporting test scenarios focused on forwarding
between an ITS-S and an RSU. The configuration contains the following entities:
• Actor - The virtual ITS-S producing the fault message or behaviour.
• Detector - The ITS-S detecting the misbehaviour and sending the MR using the short range communication
channel.
• Forwarder - The ITS-S receiving the MR from the Detector and forwarding it to the MA.
• Receiver MA - The Misbehaviour Authority receives MR from the Forwarder.
• In order to participate in the test with the present configurations, IUTs (participating entities) shall be
configured as follows: The communication network configuration is compliant with the ETSI TS 103 759 [2]
and clause 5.
NOTE: Use-case definitions may contain additional configuration details.
