SCTP-Based Pluggable Transport Prototype
by Alexander Mages 18 Sep '21

Hello Anti-Censorship Team, I was advised by Cecylia to share my project with this mailing list for the wider community to see and critique. For the past couple of months, I have been doing research under the advisory of Prof. Eugene Vasserman (CC) at Kansas State University, and this project is the result. I intend to continue working on privacy and anonymity, so if this project has potential I would be happy to keep working on it, as well as exploring other ways to contribute. The concept for this transport was derived from this wiki page: https://gitlab.torproject.org/legacy/trac/-/wikis/doc/PluggableTransports/i… . The transport is functional but not yet tested with the Tor Browser. I prototyped this transport using Ncat for SCTP and Telnet for TCP. It is written in Python 3 and SCTP functionality was implemented using C/POSIX-like socket parameters, removing the necessity of a third-party library. A write-up attached to this email denotes functionality, dependencies, limitations, and instructions for running the transport. I look forward to hearing everyone's thoughts! Regards, Alex Mages
