A HYBRID KEY MANAGEMENT SCHEME FOR SECURE MANET COMMUNICATIONS

A.Pranusha, G. Murali

Abstract: In MANETs communication is done using a shared wireless channel. There is no provision for monitoring authority. The nodes in the network need to take the responsibility for both data transfer and also security. For robust security in MANETs, key management scheme is essential. However, secure key management is a challenging problem to be addressed. In this paper, we focused on a hybrid technique that makes use of identity and trust which enables to identify malicious nodes and also convert malicious node into a trusted node. Our hash technique is evaluated with NS2 simulations. The results reveal that the proposed system is able to identify malicious nodes in MANET and handle malicious nodes in such a way that they become trusted nodes.
