Securing Node Communication in MANET using Certificate Revocation

Abstract — Mobile Ad hoc Network is a type of network which frequently changes locations and configures itself in movement. MANETS are mobile in nature and use wireless communication, so the main disadvantage for MANETS is providing Security to the nodes. In order to secure the communication between nodes we use one important action called Certificate Revocation. The previous work is done using voting and Non-voting based communication. The proposed system uses Cluster based certificate revocation where it classifies the topology into clusters and finds the malicious nodes. It finds the false accused nodes with the help of Cluster Head (CH). The system also maintains two important lists 1) Warning List 2) Black Lists. This method overcomes the existing system by enhancing the security and increasing the performance of detecting the malicious nodes
