Identity Mapping using Cluster-based Certificate technique for Vehicular Ad-Hoc Networks

In this paper, we introduced a secure authentication technique for VANETs called Identity-Mapping using cluster-based revocation technique. In this technique, all the nodes are split into various clusters and Cluster Head is selected accordingly. The certificate authority is responsible for retracting and issuing certificates, upon the successful transmission of messages or identification of any harmful activities by any node, to the corresponding vehicles. From the simulations and comparative analysis provided in this paper, it is verified that the recommended method shows better performance when compared with the existing works.
