A lightweight and secure authentication protocol for vehicle to everything communication

With the rapid advancement of Vehicle-to-Everything (V2X) communication systems, ensuring robust security has become a critical challenge. Various studies have proposed several protocols; however, many of them may suffer from potential threats, such as impersonation attacks. This paper presents an efficient and lightweight authentication protocol for V2X communication. Our scheme uses zero-knowledge proof to perform mutual authentication without revealing the real identities in V2X communication. The proposed protocol ensures that all vehicles on the network are authenticated without compromising the integrity. Hence, the proposed scheme protects V2X communication against possible attacks. The preliminary result shows that the proposed scheme is efficient in terms of computational complexity.
