An Efficient and Secure Authentication Scheme for Vehicle Sensor Networks

An Efficient and Secure Authentication Scheme for Vehicle Sensor Networks

Vehicle sensor networks (VSNs) have applications in intelligent transportation system and smart cities, as they enable vehicles to exchange information for improving traffic security and efficiency. However, VSNs are also subject to a broad range of attacks, including those typically associated with wireless networks. While a large number of authentication schemes have been proposed in the literature, most of these schemes failed to achieve the claimed security attributes. For example, Zhou et al. (2017) proposed a trust-extended authentication scheme for VSNs. However, their scheme cannot provide user anonymity or security against several known attacks as claimed. Thus, we construct a new authentication scheme based on Elliptic Curve Cryptography (ECC), and demonstrate our scheme is secure in the random oracle model. We also show that our scheme can satisfy a number of security requirements. Finally, findings from the performance evaluation suggest that our scheme is more practical for VSNs deployment.
