This thesis detailedly researches into source authentication , introducing and analyzing some previous source authentication methods . it analyzes a source authentication method ( tesla ) which is being paid more and more attention nowadays , its function , shortcoming and current improvement , and points out its secure vulnerability . we draw a conclusion : though tesla has many advantages , such as the low communication cost , tolerance of pack loss , there are still many problems , which mostly arise from the requirement of synchronous time
并对其中一种目前广泛受到人们关注的源认证方法tesla协议进行了研究，包括对tesla的功能、原理、缺陷以及现有的改进做了分析，指出其中的安全漏洞，并得到以下结论：尽管tesla有许多优点，如低通讯成本，较好的抗丢失性，但它仍然存在许多难以克服的缺陷，而这些问题主要是由于tesla所依赖的时间同步机制在现有网络环境下不易实现所带来的。
