摘要：In vehicular ad-hoc networks for authentication Public Key Infrastructure (PKI) was used as VehicularSignature application. PKI is used to verify the integrity of messages and the identity of message senders. Road Side Unit(RSU) verifies received messages one after another, it may not be able to be predicted and known by RSU i.e. from whichvehicle message is being sent. In order to reduce the computational overhead of RSUs, we propose a Proxy BasedAuthentication Scheme (PBAS) using distributed computing. In PBAS, proxy vehicles are used to authenticate multiplemessages with a verification function at the same time, so that RSU can independently verify the outputs given by eachproxy vehicles within its range. We also design an expedite key negotiation scheme for transmitting sensitive messages
