Vehicular ad-hoc networks (VANETs) are the fundamental technology for the Intelligent Transportation System (ITS) that provides drivers with a safe and comfortable driving environment. However, the inherent openness of the VANETs wireless communication channel calls for careful scrutiny of its security, privacy and efficiency. This paper proposed a New and Efficient Conditional Privacy-Preserving Authentication (NE-CPPA) scheme to secure the communication in VANETs. NE-CPPA uses the Elliptic Curve Cryptography (ECC) algorithm to fulfil the security and privacy requirements. The security analysis of the proposed scheme under various attack scenarios are presented. Then, the computation and communication costs analysis is conducted to show its feasibility and robustness. Performance evaluation showed that the NE-CPPA scheme has a lower system overhead in terms of computation and communication costs than existing schemes. Thus, the proposed NE-CPPA scheme is appropriate for securing the deployment and adoption of VANETs.
