摘　　要：简要介绍了现存的组播源认证方案,指出其优点和缺点。同时,基于树链认证技术提出了一种新的组播源认证方案,该方案中,不同数据块的摘要之间采用类似于T-CSA的方法串联起来,扩展了T-CSA的优越性,减少了延迟;而且随着数据流的不断增大,数据包的平均认证代价呈下降趋势,这对于资源有限的成员机器来讲非常重要。This paper briefly reviewed the existing source authentication schemes and described the advantages and disadvantages of these schemes. Then, proposed a new source authentication scheme based on tree chaining, in which, the abstract came from different block was connected used the technology similar T-CSA, thus expanded the superiority of T-CSA and reduced the average delay on every packet. Moreover, the average authetincation price on each packet will drop along with the unceasingly increases of the data stream, this is very important to the member machines with limited resources.
