Efficient Method for Secure Transmission from Malicious Nodes through Certificate Authentication

M.L.Vijin Stephi and Dr.B.Latha

The main reason for switching from wired network to wireless is the dynamic nature of the nodes. Since the nodes in the MANET have the capability of moving, there is a high possibility of violating the security of the network. The certificate verification involves maintaining secure connections against spoofing and invalid certificates; and the certificate validation examines the certificates to check the recipient’s identity. In this paper we proposed a scheme called certificate revocation to prevent the network from malicious attacks. If the certificate of the malicious node is revoked, then it is impossible to communicate with any other nodes in the network by the malicious node. By doing so, it is possible to have Cluster-to-Cluster communication in a secure manner.
