“…To illustrate the computation cost of our scheme clearly, we provide the real-world benchmark in CHARM of different operations in three types of elliptic curves as shown in Table VIII. Furthermore, to present the performance differences, we compare the computation cost of verification of our scheme, and the other two schemes proposed by Zeng et al [13], and the other two schemes proposed by Zeng et al [13], Jiang et al [14] respectively. Zeng et al's scheme is based on symmetric bilinear pairing, while Jiang et al's scheme is based on a normal elliptic curve.…”

“…Because the approaches in Jiang et al's scheme [14] is based on the ElGamal cryptosystem where the generated signature consists of group elements in pairs. On the other hand, the generated signature based on bilinear pairing could consist of one group element (e.g., short signature).…”

Vehicular ad-hoc networks (VANETs) are one of the most important components in an Intelligent Transportation System (ITS), which aims to provide information communication between vehicles. A safety-critical vehicular communication requires security, privacy, auditability and efficiency. To satisfy these requirements simultaneously, several conditional privacypreserving authentication schemes are proposed by employing ring signature. However, these methods have been paid too little attention to the issues like how to choose the valid ring members or how to set up a ring. In this paper, we introduce an efficient conditional privacy-preserving scheme which provides an appropriate approach establishing the list of ring members. Moreover, our proposed scheme also supports batch verification to significantly reduce the computational cost. According to the analysis of security, our scheme is sufficiently resistant against several common attacks in VANETs. The performance results show that the proposed scheme is efficient and practical with both low computation and communication cost.
