IP组播不可否认数据源认证研究进展

Progess of the Research on IP Multicast Data Origin Authentication with Non-repudiation

数据源认证是组播安全体系中重要的一部分,数据源认证可以分为可否认的和不可否认的两种。该文按照协议分类分别概述了几个具有代表性的不可否认数据源认证协议,并对每一个协议的优缺点和存在问题进行了讨论。对目前IP组播不可否认数据源认证协议进行了总结,并讨论了不可否认数据源认证未来的研究方向和还需要解决的问题。

Data origin authentication is an important part in the multicast security architecture. Data origin authentication can be classified as repudiation and non-repudiation. In this paper, several typical data origin authentication protocols with non-repudiation are summarized according to the taxonomy of data origin authentication with non-repudiation. The advantages and shortcomings of these protocols are discussed respectively, also the problems existed are anatomized in depth. This paper is a sum-up of the protocols of data origin authentication protocols with non-repudiation at the present time. The future trend and the remaining problems of data origin authentication with non-repudiation are also discussed.
