V2X Misbehavior and Collective Perception Service: Considerations for Standardization

Connected and Automated Vehicles (CAV) use sensors and wireless communication to improve road safety and efficiency. However, attackers may target Vehicle-to-Everything (V2X) communication. Indeed, an attacker may send authenticated-but-wrong data to send false location information, alert incorrect events or report a bogus object endangering other CAVs' safety. Currently, Standardization Development Organi-zations are working on developing security standards against such attacks. Unfortunately, current standardization efforts do not include misbehavior specifications for advanced V2X services such as Collective Perception (CP) yet. This work assesses the security of CP Messages and proposes inputs for consideration in existing standards.
