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.
