The road to a successful introduction of vehicularcommunications has to pass through the analysis of potential security threats and the design of a robust security architecture able to cope with these threats. Broadcast communications are critically important, as many safety-related applications rely on single-hop beacon messages broadcast to neighbor vehicles. It becomes a challenging problem to design a broadcast authentication scheme for secure vehicle-to-vehicle communications.In this paper, we undertake this challenge. In this paper, communication technique is used for improved road safety with aid of Secure Prediction based authentication scheme. Here, Beacons are used for secure V2V and V2R communication. When a large number of beacons arrive in a short time, vehicles are vulnerable to computation-based Denial of Service (DoS) attacks that excessive signature verification exhausts their computational resources. In contrast to most existing authentication schemes, our SPBAis an efficient and lightweight scheme since it is primarily built on symmetric cryptography. To further reduce the verification delay for some emergency applications, SPBA is designed to exploit the sender vehicles ability to predict future beacons in advance. In addition, to prevent memory-based DoS attacks, SPBA only stores shortened re-keyed Message Authentication Codes (MACs) of signatures without decreasing security.
