The document addresses on-board authentication and authorization in connected vehicles, a complex area involving multiple stakeholders, use cases, implementations, and standards. The core challenge is distinguishing legitimate remote interactions from misuse, manipulation, and integrity loss. Discussions have occurred since 2023 across GRVA, CS/OTA, and WP.29. FIA seeks feedback on establishing the topic and will develop a scoping document and demonstrator based on select use cases including accident investigation, law enforcement, emergency response, energy monitoring, battery tracking, parts replacement, and ITS-related safety. Contracting parties are invited to submit comments and use cases by 15 June 2026 for consideration at the November WP.29 session.
