An Efficient Key Management Protocol for Group Security on MANET Routing
Bhawna Sharma, Rohit Vaid
Security in Mobile Adhoc Networks (MANETs) is most vulnerable area of concern due to its dynamic topology; centralize-less authority and shared wireless infrastructure. Group security using key management during communication is the area of consideration when communicating to a group. In this paper, anensemble of RSA and DH (Diffie-Hellman) algorithm is used for providing security during communication in group. This ensemble key management scheme is applied on AODV and performance is analysed using parameters like routing overhead, throughput and security level. After applying this algorithm, we have found that our proposedensemble methodreduces the routing overhead in different groups, improves the throughputapplying by varying the number of messagesand secure group communicationas compared to DiffieHellman. By combining RSA and DH the group security increased by 30% from the previousDiffie-Hellman.
