基于Tor的混合匿名转发系统

随着互联网应用的不断增加，人们对网络通信的保密性也越来越重视。Tor匿名通信系统具有低时延、数据加密传输，安全信道等优点，能够有效保护通信者的信息安全，目前正成为一种流行的匿名通信系统。但随着Tor系统使用和研究的人增多，Tor系统本身的一些缺陷给其安全带来了隐患。为此，在现有Tor系统分析的基础上，文中提出了一种安全新型的混合匿名转发系统H—Tor。该系统由Hordes和Tor有效级联组合，充分发挥了两者的优势。分析表明，H—Tor可以抵御通信流攻击和端对端攻击，有效保护通信者的匿名安全。

A Mixed Anonymous System based on Tor

With the continuous increase of lnternet applications, people pay much attention to the confidentiality of network communications. Tor anonymous communication system, with low latency, data eneryption transmission, secure channel, etc., could effectively protect the information security of the correspondents, and thus becomes a popular anonymous communication system. However, with in-depth study wide use of the Tor system, Tor presents some defects in security risks. Currently, a new system called H-Tor is proposed upon the analysis of Tor. The system combines Hordes with Tor and gives full play to their advantages. Analysis shows that the H-Tor integration can effectively protect the anonymity of the correspondents.
