英文摘要：

This paper proposes an effective and secure multilayer group key management scheme,which achieves the production of the group keys and the building of communication channels by building multiple key chains.This scheme has several features,such as producing group keys and communication keys safely and quickly and quantitative distribution according to original requests.It is applicable to topological Ad hoc network,in which the nodes have limited computational and memory resources.
