Samuel Russell wrote a dissertation entitled -- Innocuous Ciphertexts: The DE-CENSOR Scheme.
The thesis can be accessed here.
As the thesis explains, I have produced a detection scheme to identify TOR traffic and an encryption scheme to bypass this detection.
The core of the code that implements these features, as well as some example traffic, is hosted in a public git repository.
Furthermore, to show an example of the DE-CENSOR scheme in action, the original FTE proxy system has been adapted to incorporate the new cryptographic primitive. The code for this is again hosted in a public git repository.
