Proposed Efficient Conditional Privacy-Preserving Authentication Scheme for V2V and V2I Communications Based on Elliptic Curve Cryptography in Vehicular Ad Hoc Networks

Abstract

AbstractVehicular ad hoc networks (VANETs) are the promising innovation for intelligent transportation systems facilitating the broadcasting of traffic-related messages that provide updated information about traffic, road conditions, and driving environments. Unfortunately, the inherent openness of the communication channel utilized by VANETs discloses the system to issues of security and privacy. Several scholars have proposed schemes to overcome the issues for a safe VANET deployment. Nevertheless, several existing schemes suffer from huge computational or communicational overhead costs. An efficient conditional privacy-preserving authentication (E-CPPA) scheme based on elliptic curve cryptography is proposed to address this issue. E-CPPA improves the efficiency of message signing and verification for the vehicle to infrastructure communication and vehicle to vehicle communication in the VANETs system. The objective of the E-CPPA scheme is to fulfill requirements regrading to security and privacy of VANETs. Finally, this paper does not only discuss the critical review on related works in VANETs but also presents the expected result for the E-CPPA scheme and future works.KeywordsVehicular ad hoc networks (VANET)Privacy-preserving-VANETAuthentication-VANETIdentity-based cryptography-VANET
