发布时间：2018-11-26 19:58
【摘要】：随着互联网日益深入人们的生活，网络匿名通信技术成为保障人们网络隐私的重要手段。这类技术帮助人们隐藏自身的具体身份，从而推动那些不想透露个人身份信息的人参与到特殊的网络活动之中。而Tor匿名通信系统是现今最为实用和有效的匿名通信系统，对其的研究是当今网络安全领域的一个热点。 本文提出了基于Tor匿名通信系统的反向匿名信道建立技术，用以拓展Tor匿名通信系统的HiddenService协议，，以提供更加安全和高效的能够保证通信双方匿名性的通信机制。本文的主要工作如下： 首先，本文简单介绍了Tor匿名通信系统的工作流程、相关协议和网络仿真。具体介绍了如何在私有网络内成功仿真Tor匿名通信系统，且额外给出了两种局域网仿真的方法。 其次，本文针对Tor源码进行了详细的分析。具体介绍了Tor源码的依赖库，并详细分析了Tor源码的重要组件以及程序核心工作流程。 再次，本文提出了反向匿名信道建立技术。基于Tor匿名通信系统之中的HiddenService协议进行拓展，设计了反向匿名信道建立的基本方案。 最后，本文对HiddenService原始协议与其拓展协议进行了局域网和互联网的对比实验。通过对比实验，实际测量验证了HiddenService拓展协议比原始协议在效率上的提高，并分析说明了拓展协议比原始协议在安全性上的提高。
[Abstract]:With the development of Internet, anonymous communication technology has become an important means to protect people's privacy. Such technologies help people hide their identity and promote the participation of those who do not want to disclose their personal identity into specific online activities. Tor anonymous communication system is the most practical and effective anonymous communication system, and its research is a hot spot in the field of network security. In this paper, a reverse anonymous channel building technique based on Tor anonymous communication system is proposed to extend the HiddenService protocol of Tor anonymous communication system, so as to provide a more secure and efficient communication mechanism that can guarantee the anonymity of both communication parties. The main work of this paper is as follows: first, this paper briefly introduces the workflow of Tor anonymous communication system, related protocols and network simulation. This paper introduces how to simulate Tor anonymous communication system successfully in private network, and gives two methods of LAN simulation. Secondly, this article carries on the detailed analysis to the Tor source code. The dependence library of Tor source code is introduced in detail, and the important components of Tor source code and the core workflow of the program are analyzed in detail. Thirdly, this paper puts forward the technology of setting up reverse anonymous channel. Based on the extension of HiddenService protocol in Tor anonymous communication system, the basic scheme of setting up reverse anonymous channel is designed. Finally, the HiddenService protocol and its extension protocol are compared with LAN and Internet. Through the comparison experiment, the efficiency of the HiddenService extension protocol is proved to be higher than that of the original protocol, and the improvement of the security of the extension protocol compared with the original protocol is analyzed.
