Efficient Anonymous Authentication and Key Management Schemes for Secure Service Provision in VANETs

With the advancement of wireless communication technologies, the vehicular ad-hoc networks (VANETs) play an important role in providing better driving experience to vehicle drivers. Due to the open wireless nature of air communication medium in vehicular ad-hoc networks (VANETs), security and privacy should be given to protect the VANETs from various security breaches or security attacks. Eventhough, there were many existing schemes available related to security and privacy, these schemes have been suffered by high computational complexity. In this project, a computationally efficient anonymous authentication technique is proposed along with an efficient key sharing mechanism to securely share information among vehicles. The security analysis section shows that the proposed scheme can withstand against various security attacks. The performance analysis section demonstrates that the proposed scheme is efficient in terms of computational complexity.
