Providing security for messages in group communication is more essential and critical nowadays. In group oriented applications such as Video conferencing and entertainment applications, it is necessary to secure the confidential data in such a way that intruders are not able to modify or transmit the data. Key transfer protocols fully rely on trusted Key Generation Center (KGC) to compute group key and to transport the group keys to all communication parties in a secured and secret manner. In this paper, an efficient key generation and key transfer protocol has been proposed where KGC can broadcast group key information to all group members in a secure way.
