Abstract
The disclosure includes embodiments for an ego vehicle to detect misbehavior. According to some embodiments, a method includes receiving a V2X message from an attacker. The V2X message includes V2X data describing a location of an object at a target time. The method includes receiving a set of CPMs from a set of remote devices. The set of CPMs include remote sensor data describing a free space region within the roadway environment. The method includes determining a relevant subset of the CPMs include remote sensor data that is relevant to detecting misbehavior. The method includes determining, based at least in part on the remote sensor data of the relevant subset, that the object is not located at the location at the target time. The method includes detecting the misbehavior by the attacker based on the determination that the object is not located at the location at the target time.
