Abstract: Mobile adhoc network (MANET) is an integration of nodes where a node can be sender, recipient or relay and may be unaware until they come in contact with each other. Communication in such a network should be secured as topology, bandwidth, network size, resources etc. changes. The core aspect of establishing secured communication can be done with the help of authentication check by exchanging keys. In this paper, we propose a novel approach for group key management scheme by simple rekeying technique on frequent scalable and high mobility nodes.
