Abstract
We use an anonymous authentication involving a central authority and a prioritized weighted fair queuing based verification scheme for the IEEE Wireless Access in Vehicular Communications based vehicular ad-hoc networks (VANETs). The proposed approach has reduced computational load for processing periodic road safety messages. Based on vehicle’s current GPS position information, a group ID based elliptic curve digital signature algorithm is used. This excludes the necessity of third party public key certificate for message authentication in VANETs. A high-density road traffic condition constitutes a challenge for authentication of vehicular messages, since the required verification time is much longer than the average inter-arrival time. In order to reduce the effects of this issue, messages of each traffic class are verified following the VANET’s medium access control (MAC) layer priorities with a Weighted Fair Queuing (WFQ) strategy and the application relevance of individual safety messages. Simulation shows that this approach is secure, privacy preserving, and resource efficient
