Dynamic multicast key management in wireless network
Yong Chen · Computer Engineering and Applications Journal · 2007
In the wireless environment,we need to allocate a group key for everyone in the group in some kinds of service.An excellent key management schemes can efficiently reduce the communication burden,improve the system performance.In this paper,we analyze the state and the problem of existing key management schemes,then propose a Logical Key Tree scheme based on physic topology.we design the scheme and evaluate the performance.Simulation results show that this scheme can reduce communication burden efficiently.
