Secure group communication is a challenging task with respect to MANETís, authentication of mobile nodes, group key establishment and rekeying for secure information exchange and QoS in data transfer.† In this paper we authenticate the mobile nodes through transitive signature scheme in the routing phase of AODV protocol.† For a secure group communication we establish a collaborative group key with the members participating in the route path to the destination. The nodes are dynamic in nature, in which any new node can join in the group or leave the group. Instead of performing individual Rekeying operations, it is performed at a particular time interval.† Performance of the group communication is compared with the existing protocols.† The analysis is made with respect to the throughput, rekeying time, delay, overhead and communication cost.† The simulation result shows that our protocol enjoys greater advantage over other protocols in the literature.
