Multi-Level ECDH-Based Authentication Protocol for Secure Software-Defined VANET Interaction

The proposed multi-layer ECDH-based authentication model and the vehicles in the VANET are authenticated and authorized to protect the network from the attacks for which the vehicles undergo the registration process initially. After the successful registration, the messages generated from the vehicles are communicated through multi-step authentication, which assures the exactness of the received messages. Then, the authorization process is executed in the VANET so as to ensure the safe and secure interactions between the vehicles. The implemented authentication model is analyzed using the comparative methods based on the performance standards, such as detection accuracy, execution time, packet delivery ratio (PDR), and throughput. The detection accuracy, execution time, PDR, and the throughput of the network while executing the proposed multi-level ECDH-based authentication system are better than the prevailing security models as the security features of the existing models are enhanced better than the existing state-of-the-art methods.
