Vehicular Ad-hoc Networks (VANETs) are upcoming technology becoming essential with development of the vehicle industry and wireless communication technology. Here vehicles as mobile nodes are a subclass of mobile ad hoc networks (MANETs) to provide communications among nearby vehicles and between vehicles and nearby roadside equipment. Security is a key requirement of VANETs.
This technology provides lightweight decentralized authentication and key agreement scheme for VANETs. It provides a host of approaches for security. First approach is the use of three types of mutual authentication: 1) between vehicles, 2) between vehicles and their respective cluster heads, and 3) between cluster heads and their respective roadside units. Second, secret keys between roadside units for their secure communications are maintained. Third, the cluster-based VANET network model is used to reduce the communication and computation overheads. Rigorous formal and informal security analysis assures that the proposed scheme is capable for defending various known attacks needed for securing VANET environment.
