Abstract
Autonomous vehicles (AVs) play a significant role in intelligent transportation systems (ITS), which handle vehicles without human interference. The AVs are integrated with the Internet of Vehicles (IoV) to connect with more vehicles, sensors, and fog servers and share data. This makes the vehicles vulnerable to attacks and leads to unauthorized access. To overcome this drawback, we introduced biometric authentication for secure communication of vehicles, roadside units (RSUs), and fog servers. In this protocol, we generated two session keys between entities. The communication cost, computation cost, and security parameters are compared with existing methods to show that the proposed protocol is more efficient than others. Finally, the formal and informal security analysis ensures the proposed protocol is more secure.
