Clustering Based Certificate Revocation Scheme for Malicious Nodes in MANET
T. R. Panke · 2013
Abstract- Certificate revocation is an important security component in mobile ad hoc networks. Owing to their wireless and dynamic nature, MANETs are vulnerable to security attacks from malicious nodes. Certificate revocation mechanisms play an important role in securing a network. When the certificate of a malicious node is revoked, it is denied from all activities and isolated from the network. The main challenge for certificate revocation is to revoke the certificates of malicious nodes promptly and accurately. In this paper, proposed scheme is based upon a clustering-based certificate revocation scheme, which outperforms other techniques in terms of being able to quickly revoke attackers ’ certificates and recover falsely accused certificates.
