摘　　要：多播密钥管理是确保多播安全通信的核心问题。目前,多播密钥管理多采用基于密钥树的方法,存在控制复杂、难于分布式管理、可靠性和安全性差、密钥存储量大等问题。介绍了基于秘密共享机制进行多播密钥管理的研究进展和相关成果,主要内容包括无条件安全的多轮撤消方案、基于秘密共享的多播密钥管理、多服务组密钥管理以及具有容侵能力的多播密钥管理技术。该研究为解决目前多播密钥管理存在的问题提出了新的思路和方法。Muhicast key management is the key problem for secure multicast communication. Today the key tree based method is most popular for muhicast key management, but this method suffers from such problems as complex control, poor reliability and security, and large storage requirements. This paper introduces the status of our research on muhicast key management based on secret sharing,including an unconditionally secure multi-round revocation scheme using secret sharing, a scheme for muhicast key management based on secret sharing, a scheme of multi-group key management and the technology for the muhicast key management with the intrusion tolerant capability. Our research provides new ideas and methods for solving the problems in existing schemes of multicast key management.
