Abstract
Vehicular ad hoc networks (VANETs) are proposed to improve the traffic safety and efficiency through communications among vehicles and between vehicle and roadside units (RSUs). When a vehicle broadcasts messages to nearby vehicles and roadside units (RSUs), it needs to resist attacks and to preserve the privacy of the message senders. Therefore, security and privacy issues are of great interests and remain challenging. Many authentication schemes are proposed to tackle above challenges while most of them are heavy in computation and communication. In this paper, we propose a novel authentication scheme that utilizes the double pseudonym method to hide the real identity of vehicle and adopts the dynamic update technology to periodically update the information (such as member secret, authentication key, internal pseudo-identity) stored in the tamper-proof device (TPD) to prevent the side-channel attack. Because of not using bilinear pairing, our scheme yields a better performance in terms of computation overhead and communication overhead and is more suitable to be applied in VANETs.
