FIA convened a group of interested parties to develop a scoping document on on-board authentication and authorization. Participants expressed support and called for proof of concept built around use cases. Harmonizing access methods was suggested to reduce cybersecurity fragmentation. Key question raised: which authority authenticates and grants access to legitimate parties? Next steps include establishing concrete use cases and providing a recommendation for WP.29 in November. Planned activities prior to the 200th Session of WP.29 in November include finalizing meetings with GR leaderships and other stakeholders, assembling a Group of Core CPs (GCC) to set scope based on use cases, conducting internal work, aligning with the GCC, and updating WP.29 with objective to obtain a mandate for formal work on the topic.
