Abstract: In mobile ad hoc networks (MANETs), security is more challenging due to problems related to key exchange. It is necessary to secure the exchanges in MANETs for assuring the development of services in the network. The self-organised MANET is visualised as a key communication technology enabler for application such as network centric warfare, disaster relief operations, emergency situations, intelligent transportation systems and so on. In this paper, we propose a trust prediction model for certificate exchange and revocation in MANET. The proposed architecture consists of one coordinator node, servers and normal mobile nodes. Then, multi-path certificate exchange technique is employed where public key of the nodes are certified by different nodes. Those nodes that issued the certificates are validated using the trust prediction model. The source node discards the malicious nodes in the data sending path and bypasses the data through other nodes in alternate selected path. Source performs certificate revocation process for defending against the malicious nodes based on the trust values. By simulation results, we show that the proposed approach improves security.

Keywords: mobile ad hoc networks; MANETs; trusted third party; TTP; public/private key pairs; certificate exchange; certificate revocation.
