Vehicular cyber-physical systems (CPSes) that integrate sensing, computing, control, and communication, together into various connected physical objects or infrastructures, have received significant interest in recent years. In a vehicular CPS, participating autonomous vehicles (AVs), which can be ground, aerial, or even marine, depend on reliable and secure vehicle-to-everything (V2X) communications to exchange useful information such as motion states (including positions, velocity, and acceleration), traffic conditions and road emergencies, etc. Acknowledging the correct V2X information can help system participants be aware of the environment and take proper action such as accelerating, brakes, or changing lanes, in order to enhance system safety, efficiency, as well as reduce energy cost.
