For secure group based message transmission, we must share the key among users so that we can make the transmission as secure. In this paper, we develop a security framework KAP that consists of two protocols namely, Subgroup Key Generation (SKG) and Group Key Generation (GKG) based on ECDH for subgroups and outer groups respectively. These subgroup keys and group keys should be changed when there are membership changes (such as when the current member leaves or the new member joins). Gateway member is selected for each group. By introducing group-based approach, messages and key updates will be limited within subgroup and outer group. Thus computation load is distributed to many mobile ad hoc nodes. Both theoretical and practical results show that this group key agreement protocol performs better in terms of memory storage, energy consumption, and delay.
