Implementation of cluster based certificate revocation in mobile ad hoc networks

Mobile ad hoc networks (MANETs) brings more attraction because of their mobile and simple nature of arrangement. But, their open and dynamic nature renders them more suspicious to different kinds of security attacks than the wired networks. To meet these challenges, certificate revocation is a mechanism to provide secure network communication services. Certificate revocation is used to segregate attackers from participating in network activities in future. A Cluster-based Certificate Revocation mechanism is the best scheme used to revoke the certificates of malicious node present in the network. It provides the capability of detecting the falsely accused node in the network and revokes the certificate of that node to address the problem of false accusation. To improve the reliability of this mechanism, warned nodes are kept apart from certificate revocation mechanism.
