چکیده
Censorship circumvention tools face an arms race as they work to evade increasingly motivated censors. Tools which have distinctive features can be detected and blocked by censors (e.g., Tor is actively targeted by censors around the world). As a result, there is increasing interest in disguising censorship circumvention traffic as benign protocols. SkypeMorph [1] and StegoTorus [2] are two pluggable transports [3] for Tor which aim to mask Tor traffic as Skype traffic, and a combination of Skype, HTTP and Ventrilo, respectively.
