    Abstract: The recent growth, popularity and extensive need for the deployment of group oriented applications like multiparty video conferencing, multiplayer online gaming and real time push based delivery systems has triggered the demand for secure group communication. These applications require multicast to minimize the volume of network traffic they generate. Multiparty communications have recently become the focus of new developments in the area of applications. The goal of this study is to establish a secure group communication using multicast key distribution scheme. In general, to meet forward secrecy and backward secrecy, any change in the group membership will induce group rekeying. Here, a novel key management scheme is proposed in which no redistribution of group key (shared key) is required during the group dynamics there by reducing computation and communication complexities considerably.
