摘要

通过在现有的网络协议中隐藏信息,反审查工具可以授权被审查的用户访问被封锁的网站。然而,现有的解决方案通常有两个限制。首先,他们通常需要ISP的支持或部署许多定制主机来隐藏被审查用户和被封锁网站之间的通信。其次,他们对正常网络流量的操纵可能会产生可检测的特征,这些特征可能会被审查系统捕获。在本文中,为了解决这些限制,我们提出了一个新的框架,利用公开可用的自动化服务和大量的网络服务和内容来规避网络审查,并在一个名为AutoFlowLeaker的实用工具中实现它。此外,我们进行了大量的实验来评估AutoFlowLeaker,结果表明它具有良好的性能,可以有效地逃避现实世界的网络审查。

AutoFlowLeaker: Circumventing Web Censorship through Automation Services
By hiding messages inside existing network protocols, anti-censorship tools could empower censored users to visit blocked websites. However, existing solutions generally suffer from two limitations. First, they usually need the support of ISP or the deployment of many customized hosts to conceal the communication between censored users and blocked websites. Second, their manipulations of normal network traffic may result in detectable features, which could be captured by the censorship system. In this paper, to tackle these limitations, we propose a novel framework that exploits the publicly available automation services and the plenty of web services and contents to circumvent web censorship, and realize it in a practical tool named AutoFlowLeaker. Moreover, we conduct extensive experiments to evaluate AutoFlowLeaker, and the results show that it has promising performance and can effectively evade realworld web censorship.
