一种新的基于分层分组式结构的组播密钥管理方案

摘要

This paper analyzes several distributed multicast key management schemes which are familiar to us, and presents a new construction of multicast key management based on distributed frame. The new idea is compared with the others in the term of the advantages and disadvantages by experiments.%分析了常见的几种分层分布式密钥管理方案，并且在前人的基础上提出了一种新的基于分层分布式结构的组播密钥管理构想，介绍了这种方案的基本思想。通过实验分析比较了这种方案与前人方案的不同点及相同点，以及各自的优缺点。
