Owing to dynamic topology changes in mobile ad hoc networks (MANETs), nodes have the freedom of movement. This characteristic necessitates the process of rekeying to secure multicast transmission. Furthermore, a secure inter cluster communication technique is also mandatory to improve the performance of multicast transmission. In this paper, we propose an inter cluster communication and rekeying technique for multicast security in MANET. The technique facilitates inter cluster communication by distributing private key shares to the nodes, which is performed by the centralised key manager. By tamper proofing the data using private key share, inter cluster communication is accomplished. Furthermore, the rekeying mechanism is invoked when a node joins the cluster. Our rekeying technique incurs low overhead and computation cost. Our technique is simulated in network simulator tool. The simulation results show the proficiency of our technique.
