This paper puts forward Distributed LKH group key management protocol based on HLTN key architecture.
本文提出了采用限高树密钥结构的分布式lkh组密钥管理协议。
Finally, we compare LKH with EK using experiments, and conclude that LKH is suitable for the multicast members revocation.
通过实验，对LKH方法和EK方法进行分析比较，证实了LKH适合多播组成员的撤回。
The logical key hierarchy (LKH) scheme is the most efficient protocol for key management in the field of multicast at present.
逻辑密钥层次（LKH）方案是目前多播领域中最有效的密钥管理协议。
LKH scheme is a centralized multicast key management scheme and it lightens the burden of the sever and group members efficiently, but it doesn't present the process of initialization clearly.
逻辑密钥树方案是一种集中式的组播密钥管理方案，有效地减轻了组管理器和组成员的负担，但是却没有优化组通信初始化的过程。
