Efficient Certificate Revocation of Attacker nodes in Mobile Ad Hoc Networks

Mobile Ad Hoc Networks (MANETs) is a self-configuring, infrastructure less network of mobile devices connected by wireless. The wireless and dynamic nature of MANET leads to various types of security attacks. The primary task is to provide the secure communication. To come across this challenge, we propose Cluster based Certificate Revocation with Vindication Capability scheme for certificate revocation from the attacker node and isolate the attackers from further communication in the network. In addition, we have adopted the one-hop neighbor selection method for none of the intermediate node is an attacker node from source to destination. This provides an effective and efficient secure communication in MANET.
