Once we have a recommended approach for an external program that discovers bridge addresses to tell Tor about them, we need to write proposals and start implementing them. The "and start implementation as needed" part of the deliverable text is vague enough to focus on the design discussion and proposals. If there's time left to implement something, great, but if not, that's fine, too. We can still implement proposals between March and November 2012.Mike PerryMike Perryhttps://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/trac/-/issues/5011Discuss possible designs for an external program that discovers bridge addres...2020-06-27T13:44:08ZKarsten LoesingDiscuss possible designs for an external program that discovers bridge addresses to tell Tor about themThis ticket is part of sponsor F deliverable 7.

Mike said he's going to take the lead on the discussion. Back in December we agreed on February 13 as the deadline for the discussion. Maybe we need a new deadline, but one that still leaves time for writing proposals and starting to implement them.Mike PerryMike Perryhttps://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/trac/-/issues/2860Research TCP connection patterns produced by web browsing2021-06-17T14:17:38ZRobert RansomResearch TCP connection patterns produced by web browsingWe suspect that Tor connections (and other TCP-based encrypted tunnel connections) can easily be distinguished from connections produced by a web browser by an attacker who has only logs of TCP SYN, FIN, and RST packets and the times at ...We suspect that Tor connections (and other TCP-based encrypted tunnel connections) can easily be distinguished from connections produced by a web browser by an attacker who has only logs of TCP SYN, FIN, and RST packets and the times at which they were sent. We should research this further.
The first step is to collect example recordings of the SYN, FIN, and RST packets produced by:
* a normal Tor client,
* a Tor client configured to use one bridge,
* a Tor client configured to use ten bridges,
* Firefox loading a simple (one HTML page without CSS or JS) web page over HTTPS,
* Chromium loading the same simple web page,
* Firefox viewing a JS-intensive web page (over HTTPS if possible), and
* Chromium viewing the same JS-intensive web page.
A simple visualization tool for the recordings will also be needed.Brandon WileyBrandon Wileyhttps://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/trac/-/issues/2468Try to fit triangle-boy into xxx-pluggable-transport2020-06-27T13:44:10ZMike PerryTry to fit triangle-boy into xxx-pluggable-transportWe should review the pluggable transport spec to ensure it is robust enough to handle involved designs such as the triangle boy transport:

Someone should probably also make sure a skype transport is possible, but this review is only about triangle-boy. We can do a skype design after this.Mike PerryMike Perry
