摘　　要：分布式多播是一种分布式环境下的一对多或多对多的通信技术。由于缺乏安全机制限制了分布式多播的应用。密钥管理是解决分布式多播安全通信的重要研究方法,它通过为组成员生成、分发和更新组密钥来满足加密认证等安全需求。本文从分布式多播的安全需求切入,首先分析了分布式多播密钥管理所面临的问题并对其进行了简单的概述,然后对已有的几种密钥管理方案进行了分析与比较,最后总结出了分布式多播密钥管理需要进一步的研究的方向。Distributed multicast is a one-to-many or many-to-many communication technology in distributed situation.The absence of security mechanism has limited the application of it.Key management is an important research method to solving the secure communications of multicast,and it fulfills the security requirements such as encryption and authentication by using multicast group members to generate,refresh and transfer keys.This article first analyzes the problems of distributed multicast key management,and then it gives a brief introduction to it.Secondly,several existed schemes are introduced,and finally the current situation and the trend of the distributed multicast key management are summarized.
