Poking a Hole in the Wall: Efficient Censorship-Resistant Internet Communications by Parasitizing on WebRTC
Diogo Barradas, Nuno Santos, Luı́s Rodrigues, Vítor Nunes
Abstract
Many censorship circumvention tools rely on trusted proxies that allow users within censored regions to access blocked Internet content by tunneling it through a covert channel (e.g,. piggybacking on Skype video calls). However, building tools that can simultaneously (i) provide good bandwidth capacity for accommodating the typical activities of Internet users, and (ii) be secure against traffic analysis attacks has remained an open problem and a stumbling block to the practical adoption of such tools for censorship evasion.
