Privacy‐preserving authentication protocols with efficient verification in VANETs

Abstract

SUMMARYAs an important component of intelligent transportation systems, vehicular ad hoc networks can provide safer and more comfortable driving circumstance for the drivers. However, communication security and privacy issues present practical concerns to the deployment of vehicular ad hoc networks. Although recent related studies have already addressed most of these issues, most of them have only considered a posteriori countermeasures or a priori countermeasures to prevent the attacks of an adversary. To the best of our knowledge, up to now, only two privacy‐preserving authentication schemes can provide a posteriori countermeasures and a priori countermeasures. But, the computational cost of verifying a signature is relatively high or security proof of the scheme is loose in the two schemes. In this paper, we propose two novel privacy‐preserving authentication schemes. The first one cannot only provide a posteriori and a priori countermeasures, but also has low computational cost in the verification phase and tight security proof. The second one can achieve batch verification on multiple messages. Comparison with Wu et al.'s scheme and Chen et al's scheme, our scheme shows higher efficiency in terms of the computational cost of verifying signature.Copyright © 2013 John Wiley & Sons, Ltd.

An Enhanced Privacy-Preserving Authentication Scheme for Vehicle Sensor Networks

“…However, the efficiency of this solutions is low. Zhang et al [10] presented two additional authentication schemes with privacy preservation; however, the computational costs of their methods are somewhat high because of the utilization of bilinear pairing. Similarly, Zheng et al [11] introduced an authenticated key agreement scheme based on bilinear pairing.…”

An efficient energy‐aware predictive clustering approach for vehicular ad hoc networks

“…Apart from the earlier discussed proposals, there are many other proposals that exist in the literature, which address the issues of routing and clustering in VANETs. Some of the most prominent protocols in this category are described in details in [23][24][25][26][27][28][29][30]. Rodrigues et al [31][32][33][34][35] explored the VANETs from different aspects such as network management, and delay tolerant.…”

Modeling privacy issues in distributed enterprise resource planning systems

“…Mausaji [24] dwelt on the integrated auditing of ERP systems. Privacy and security have been analyzed and modeled in different systems (e.g., [27][28][29][30][31]61]). She and Thruanisingham [26] presented security solution in ERP and directions for secure systems.…”
