PBA: Prediction-based Authentication for Vehicle-to-Vehicle Communications

Abstract— PBA: Prediction-based Authentication for Vehicle-to-Vehicle Communications. In vehicular networks,broadcast communications are critically important,as many safety-related applications rely on single-hop beacon messages broadcast to neighbor vehicles.However,it becomes a challenging problem to design a broadcast authentication scheme for secure vehicle-to-vehicle communications. Especially 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 this paper, we propose an efficient broadcast authentication scheme called Prediction-based Authentication < Final Year Projects 2016 > PBA to not only defend against computation-based DoS attacks, but also resist packet losses caused by high mobility of vehicles. . In contrast to most existing authentication schemes, our PBA is an efficient and lightweight scheme since it is primarily built on symmetric cryptography.
