Mobile Ad hoc Networks (MANETS) is collection of mobile nodes without base station. The nodes which are in MANTES will have the moving nature. Due to this nature of mobility, MANETs are susceptible to security attacks rather than wired networks. Certificate revocation is an important method to remove the misbehaving node from network by blocking its certificate. These certificates are provided and blocked by Certificate Authority (CA) which is trusted third party. Clustering of mobile nodes technique is used for managing certificates of nodes present in the cluster. CA uses the accusation message from cluster head present in the network in order to block the certificate of misbehaving node. False accusations are detected and prevented by Cluster Head (CH). This certificate blocking mechanism improves performance of network by increasing the normal nodes in network.
