# UltraSurf软件的运行机制分析

## Analysis on Runtime Mechanism of UltraSurf Software

**摘要:**UItraSurf软件是在互联网客户端运行的应用程序.它使用远程代理服务器和自定义的加密协议,可以突破传统的网络过滤,实现对远程信息的透明访问.文中采用动态反汇编技术,对该软件的通信手段和加密方式等进行了逆向分析,确定了软件的工作流程、加密算法以及网络拓扑结构,还原了软件内部的秘密信息
,并对分析结果进行了测试验证.目前,该软件是互联网上具有代表性的动态代理保密通信软件之一,因此文申的研究结果也为其它同类软件的分析提供了借鉴.
