Spoofing examples in Annex 5, Tables A1 and B1
In Annex 5, Tables A1 and B1, the examples for spoofing of messages by impersonation now include “V2X cooperative awareness or manoeuvre coordination messages”. Before, the examples included “802.11p V2X during platooning”. The GNSS messages example does not change.
Q2Why it changed
- Proposed by
- IWG on Cyber Security and OTA issues
- Working party
- GRVA, 15th session (January 2023)
Reasons
Reasons given by the proposer: IWG on Cyber Security and OTA issues, in informal document GRVA-15-05. GRVA adopted GRVA-15-05, as reproduced in Annex V, and requested the secretariat to submit it to WP.29 and AC.1 (ECE/TRANS/WP.29/GRVA/15, para. 49).
The informal working group agreed that using “802.11p” to refer to V2X communications is out of date. Other direct communication methods are in use, and 802.11p is properly referred to as 802.11-OCB.

The amendments are suggested to be more appropriate. In practical terms, they would lead to fewer interpretation requests from implementers, as the new examples would fit with mainstream implementers’ expectations.
