摘　　要：The goal of authentication scheme for Vehicular ad hoc networks(VANETs) is to ensure reliability and integrity of message. Due to the timeliness of traffic-related messages and the highly dynamic nature of VANETs, it still is a challenge to solve the three key issues simultaneously, i.e. security, efficiency and conditional privacy-preserving, on the design of authentication scheme for VANETs. To address this challenge, an efficient Conditional privacy-preserving authentication(CPPA) scheme is proposed in this paper. Compared with the most recent proposed CPPA schemes, our proposed scheme markedly decreases the computation costs of the message-signing phase and the message verification phase, while satisfies all security requirements of VANETs and provides conditional privacy-preserving.The goal of authentication scheme for Vehicular ad hoc networks（VANETs） is to ensure reliability and integrity of message.
