A Secure and Efficient Scheme with Batch-Verification for Vehicular Ad-Hoc Network

Abstract

Abstract-Vehicular ad hoc network (VANET) is a special kind of Mobile ad hoc network (MANET) which can improve the traffic control systems. Due to the limitation of wireless communications, efficiency and bandwidth are two important issues need to be considered for its design. In this work, we design a secure and efficient scheme with batch-verification for vehicular ad hoc network. Compared to existing secure VANET-based authentication schemes, our scheme has higher efficiency and lower bandwidth.
