Abstract: The paper discusses the application requirements and basic design principles for the existing IP multicast source authentication schemes. Several typical authentication schemes are briefly analyzed. Qualitative analyses of these schemes show the overall performance characteristics and quantitative analyses present the overhead of these schemes. When designing practical IP multicast source authentication schemes, qualitative and quantitative analyses can help to choose the scheme which best meets the application requirements.

Key words: IP multicast, source authentication, Hash, message authentication code(MAC)

摘要：

分析了IP组播源认证方案的应用需求及设计基本原则，介绍了一些有代表性的源认证方案的基本思想并作了定性分析，从总体上把握了方案的性能特征，定量地分析了其开销情况。在设计实用的IP 组播源认证方案时，可以依据定量及定性分析的结果，挑选最能满足应用需求的方案。
