并在集中式和分布式两种组密钥管理方案的基础上，提出了新的层簇式密钥管理架构，并解决了这两种方案存在的安全缺陷。
According to the root-controlling and distributing group key management schemes, this paper proposes a novel layer-cluster key management technique and resolves specific defects of the two schemes.
与传统网络不同的是传感器网络不存在这种可信节点，而且其资源十分有限，因此传统网络中的组密钥管理方案不适合传感器网络。
Different from the traditional networks, sensor networks don't have such reliable nodes and their resources are constrained. So all these schemes can't be used in sensor networks directly.
该文分析比较了各种密钥管理方案，认为组密钥管理更适合于无线传感器网络。
