安全组播中的组密钥管理研究进展

A Survey of Group Key Management in Secure Multicast

随着因特网上应用的发展,IP组播技术得到了广泛的应用。现在对于组播技术的学术研究已经 成为了一个活跃的领域,而作为组播应用中关键技术的安全组播也得到了很大的重视。在这篇文章中,我们描 述了安全组播的核心——组密钥管理,主要对集中式组密钥管理方法进行比较,并指出了未来的研究方向。

With the development of applications on Internet, IP multicast has been widely used. Now, research on multicast has become an active area, and secure multicast, which is the key technology in muldcast applications, gets much attention. In this article, we describe the core of secure multicast-group key management, mainly compare the centralized group key management methods, and future works are also analyzed.
