  Connected and Automated Vehicles use sensors and wireless communication to
improve road safety and efficiency. However, attackers may target
Vehicle-to-Everything communication. Indeed, an attacker may send authenticated
but wrong data to send false location information, alert incorrect events or
report a bogus object endangering the safety of other CAVs. Currently,
Standardization Development Organizations 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 yet. This work assesses the security of Collective
Perception Messages and proposes inputs for consideration in existing
standards.
