Abstract

Key management is an essential part of multicast security. The distribution of keys in an authenticated manner is a ­difficult task in MANETS and when a mobile node leaves or joins generates new session key. The combination of Enhanced Distributed Weighted Clustering Routing Protocol (EDWCRP) and RSA has been proposed to secure multicast key distribution. Cluster Head (CH) maintains the group key and it also updates the group key whenever there is a change in the membership. A Secondary Cluster Head (SCH)is also elected to avoid the CH from becoming a bottleneck. Mobile nodes get authenticated using MD-5 hash authentication mechanism. The performance of the system is evaluated based on attackers and metrics like Packet Delivery Ratio, energy consumption and packet drop. As demonstrated by simulation results, the proposed algorithm improves the overall performance and reduces energy utilization.
