StegoP2P: Oblivious user-driven unobservable communications

With increasing concern for erosion of privacy, privacy preserving and censorship-resistance techniques are becoming more and more important. Anonymous communication techniques offer an important method defending against Internet surveillance, but these techniques don't conceal themselves when used. In this paper, we propose StegoP2P, an unobservable communication system with Internet users in overlay network that relies on Innocent users' oblivious data downloading, StegoP2P works by deploying a end-to-middle proxies, which inspect special steganography flows from StegoP2P users to innocent-looking destinations and mirror them to the true destination requested by oblivious P2P users. The hidden communication is indistinguishable from normal network communications to any adversaries without a private key, hence, making the StegoP2P clients unobservable. We have developed a proof-of-concept application based on Vuze and conducted evaluations through experiments.
