组播以其独特的优势，在网络通信方面的应用越来越广泛，但随之而来的就是安全问题，其中密钥管理是最基本的问题之一。本文研究了安全组播中的密钥管理问题。介绍了现有的两种主要解决方案，即SKDC方案和密钥树管理方案，并分析了它们的不足之处，指出基于密钥树的研究方向，在此基础上提出基于Huffman密钥分级树的密钥管理方案，将布尔函数的分析方法运用其中使管理简便化。并对该方案的性能从密钥管理的存储空间和密钥刷新通信量两个方面，给出了相应的分析。-Multicast With its unique advantages in the communication network is widely applied, but the attendant security issues, key management is the most basic one of the problems. This paper studies the security Multicast key management issues. Of the two main existing solutions, and key programs SKDC tree management program analysis of their deficiencies, that the tree on the key directions of research on this basis based on the classification tree Huffman key Key Management Program, Boolean function of the analytical method which enable the use of simple. Program and the performance of key management from the storage space and traffic Key set two, given the corresponding analysis.
