Title
Message Authentication Using Proxy Vehicles in Vehicular Ad Hoc Networks
Abstract
Normally, authentication in vehicular ad-hoc networks (VANETs) uses Public Key Infrastructure (PKI) to verify the integrity of messages and the identity of message senders. The issues considered in the authentication schemes include the level of security and computational efficiency in verification processes. Most existing schemes focus mainly on assuring the security and privacy of VANET information. However, these schemes may not work well in VANET scenarios. For instance, it is difficult for a RoadSide Unit (RSU) to verify each vehicle’s signature sequentially when a large number of vehicles emerge in the coverage areas of an RSU. To reduce the computational overhead of RSUs, we propose a Proxy Based Authentication Scheme (PBAS) using distributed computing. In PBAS, proxy vehicles are used to authenticate multiple messages with a verification function at the same time. In addition, RSU is able to independently verify the outputs from the verification function of the proxy vehicles. We also design an expedite key negotiation scheme for transmitting sensitive messages. It is shown from the analysis and simulations that an RSU can verify 26500 signatures per second simultaneously with the help of the proxy vehicles. The time needed to verify 3000 signatures in PBAS can be reduced by 88% if compared to existing batch-based authentication schemes.
