AbstractWith the rapid advancement in connected and automated vehicle technologies, a widespread use case cooperative adaptive cruise control (CACC)-based platooning is gaining momentum. The CACC-based platooning can enhance safety and driving comfort, increase traffic throughput, and reduce fuel consumption and pollutant emissions. Various platooning maneuvers, such as merge, split, lane change, leave, etc., have been integrated with CACC-based platooning to meet the objectives mentioned above. In such a platooning, a platoon leader plays a crucial role in the execution of various functions such as synchronization, collision avoidance, coordination, and better route planning. However, if a malevolent vehicle becomes the leader, it may put the entire platoon in danger. Thus, it is very crucial for vehicles to elect a trusted and reputable leader to lead the platoon. The unencrypted broadcast inter-vehicle communication of CACC exposes vehicles to several security threats. Establishing trust among vehicles is a critical ...
