BRAT: An Efficient Signature Scheme for Vehicular Networks Using Binary Re-Authentication Tree

In this paper, It propose Binary Re-Authentication tree a relatively efficient signature scheme for vehicle - to infrastructure communication. The BRAT Scheme can use Secure Hash Algorithm (SHA) algorithm can efficiently eliminate the performance bottleneck when verifying a mass of signatures with other verifying a mass of signatures with other ECDCA algorithm for the solution of bogus messages and DOS-tolerant signature scheme. In addition, Zero Knowledge Protocol (ZKP) to address this problem of re-authentication and achieves Re authentication by neighborhood authentication of the node that wants to rejoin the network. In addition it attempts to identify the possible future direction for this field. It also discusses the implementation details of these systems including the phases by them and the metrics are used to measure the performance. It offers the other conventional security for vehicular networks, such as privacy identification and traceability.
