Multi-privileged group communications have been widely used in the Internet, like live sports, video conferencing, etc., because of its high efficiency in transporting information flows. However, security has been challenged seriously, which limits the development of correlative network service applications. In this paper, to make up for the shortages of former studies, we proposed a multi-privileged group key management scheme based on information flow policy which is introduced to security group communication system for the first time. We also apply the idea of virtual user group to improve the scability of our scheme. Finally, we develop a simulation model to valuate its performance. The simulation results show that the proposed scheme can greatly reduce the storage overhead and rekeying overhead and is suitable for complicated environments.
