In vehicular ad-hoc networks for authentication Public Key Infrastructure (PKI) was used as Vehicular Signature application. Using PKI scheme integrity of message and identity of senders can be verified. In this scheme task of Road Side Unit (RSU) is to verify received messages one by one, and if this is the case then it is difficult to guess the identity of a vehicle by RSU i.e. from which vehicle particular message is being sent. So Proxy Based Batch Authentication Scheme is being proposed in order to reduce computational overhead of RSU in distributed computing system. In PBAS, each proxy vehicle authenticates multiple messages simultaneously using verification function at the same time, so that RSU can independently verify the outputs given by each proxy vehicles within its range.
