Conditional Privacy-Preserving Authentication Scheme for IoV Based on ECC
摘要
Internet of Vehicles (IoVs) is an important part of intelligent transportation systems that could improve the safety and efficiency of vehicle nodes. However, due to the mobility of IoVs, there are some security and privacy concerns in IoVs. The conditional privacy-preserving authentication (CPPA) scheme based on Elliptic Curve Cryptography (ECC) is proposed in this paper. This paper uses the small exponent test technology to achieve batch verification of multiple messages through Road Side Unit (RSU). To achieve anonymous authentication, our scheme uses the real identity of the vehicle node to generate an anonymous identity. According to security proof, our scheme can against adaptively chosen message attacks in the random oracle model. Furthermore, according to performance evaluation, our scheme reduces computation and communication costs without bilinear pairing. Therefore, our scheme is safer and more efficient than previous schemes, suitable for IoVs.
