Dust: A Blocking-Resistant Internet Transport Protocol

Censorship of free speech on the Internet has been an increasing problem as the methods of identifying and filtering traffic have become more sophisticated. A number of approaches to counteract Internet censorship have been implemented, from censorship-resistant publishing systems to anonymizing proxies. While existing systems provide protection against some attacks, they fail to provide resistance to blocking of the transport protocol by modern techniques such as Deep Packet Inspection. Dust is proposed as a blocking-resistant Internet protocol designed to be used in conjunction with existing systems to add resistance to a number of attacks currently in active use to censor Internet communication.
