Abstract
In this paper, Cluster-Based Secure Communication and Certificate Revocation Scheme for VANET is proposed. Initially, the nodes (vehicles) are gathered into various clusters and cluster head (CH) should be selected based on the trusty nodes. The certificate authority (CA) known as the trusted third party is taken into account, however, CA is in charge of revoking and distributing the certificates that belong to the vehicles. The information of the certificate revocation list is provided to the CA. Any cluster member can obtain the details from CH if it identifies valid certificate of the secure transmission of messages that takes place by the application of symmetric cryptography approach, where the encryption and the decryption of certificates may occur. From the simulation result, it is verified that the proposed method shows better performance when compared with the existing works in terms of the delivery ratio, throughput, and latency, etc.
