== Discussion ==

* Snowflake in Turkmenistan: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/issu...         * we are providing a different snowflake bridgeline with specific port for stun servers and azure and domain front         * the changes seems to work for AGTS (one ISP) but not for others, as they block port 3478 and 3479

* TorCloak Integration with BridgeDB         * We are currently developing a new Tor Pluggable Transport called TorCloak. TorCloak's basic mechanism is to conceale Tor traffic on the video streams of WebRTC-based video conferencing services.         *  We are now coming to a stage on our project in which we are discussing solutions to disseminate our bridges.         * Sent a draft of the solution via the mailing list.             * https://lists.torproject.org/pipermail/anti-censorship-team/2022-August/0002...         * Get everyone's opinion and feedback on the solution

(New)     * Next Step for WebTunnel         * https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/webtu... == Actions ==

== Interesting links ==

== Reading group ==

* We will discuss "An Empirical Analysis of Plugin-Based Tor Traffic over SSH Tunnel" on Sept 8         * https://ieeexplore.ieee.org/document/9020938         * PDF available from Sci-Hub, DOI 10.1109/MILCOM47813.2019.9020938         * Questions to ask and goals to have:             * What aspects of the paper are questionable?             * Are there immediate actions we can take based on this work?             * Are there long-term actions we can take based on this work?             * Is there future work that we want to call out in hopes that others will pick it up?
