Key Management and Group Key Agreement For Fast Transmission To Remote GroupsApril 3rd, 2014
In newly emerging networks, securely and efficiently broadcasting to a remote cooperative group is a major problem. In this paper, a novel key management approach is proposed to solve this problem. The new approach is a cross of existing broadcast encryption and group key agreement. In this approach, each node maintains a public/secret key pair. By seeing the public/secret key of the node, a sender can securely broadcast to any group. The proposed method is to enable send and leave broadcast to remote cooperative groups. If the non intended members collude, they cannot extract any information from the transmitted messages. The proposed approach provides efficient member deletion/addition, flexible rekeying strategies and is also efficient in terms of communication.
