We propose an unobservable censorship-resistant infrastructure, called FreeWave. FreeWave works by modulating a client’s Internet traffic into acoustic signals that are carried over VoIP connections. The use of actual VoIP connections, as opposed to traffic mimicking, allows FreeWave to relay its VoIP connections through oblivious VoIP nodes, hence keeping the FreeWave server(s) unobservable and unblockable. We prototype FreeWave over Skype.
