| 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。

| Abstract: | 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,t... |
