In vehicular ad-hoc networks for authentication Public Key Infrastructure (PKI) was used as vehicular signature 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 which vehicle message is being sent. In order to reduce the computational overhead of RSUs, the authors 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, so that RSU can independently verify the outputs given by each proxy vehicles within its range.
