Abstract: In this paper, we introduce a robust authentication protocol for Vehicle-to-Grid (V2G) communication through lightweight and secure cryptographic primitives. In addition, we utilize signcrypt and unsigncrypt functions which facilitate the consumers to have secure access to the services. The security evaluation of the introduced framework shows its resilience against well-known security attacks. Moreover, the performance analysis shows that our protocol is efficient and reliable as compared to various related protocols but energy and computation cost is slightly higher than four other related protocols.
