Secure Group Key Management using Ciphertext in MANETs
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 1
Abstract
Abstract: The modern developments in Mobile AdhocNETworks (MANETs) suffer from efficient and secure broadcasting of messages to a distant system. The main obstacles for the secured information transfer are restricted communication from the cluster/group nodes to the sender and unavailability of a trusted public/private key generation center. This paper proposes a technique that uses a combination of broadcast encryption technique and Cluster/Group key agreement to overcome the obstacles. Among the proposed techniques each member maintains one public/secret key pair, seeing that the remote sender broadcasts to the subgroup. Though the non-intended member conspire they will not extractinformation that boosts security of the message. The Cluster /Group size is independent of computation and communication overhead that decreases the delay. The proposed technique provides competent approach to add or delete members of a cluster and a flexible rekeying strategy. In case of conspiracy it provides security to the broadcasted data. Simulation results are given using NS2.
