onyinyang: 2023-03-14
Last week(s):
- continued prep for HACS/DRL meeting
- Sync-test rebase
This week:
\- continue prep for HACS/DRL meeting
\- Attend HACS, then RWC, then DRL meeting
\(later things\)
\- improve metrics collection/think about how to show Lox is working/valuable
\- sketch out Lox blog post/usage notes for forum
\- attempt hyper upgrade again
\(long term things were discussed at the meeting\!\): https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep
\- brainstorming grouping strategies for Lox buckets \(of bridges\) and gathering context on how types of bridges are distributed/use in practice
Question: What makes a bridge usable for a given user, and how can we encode that to best ensure we're getting the most appropriate resources to people?
1\. Are there some obvious grouping strategies that we can already consider?
e\.g\., by PT, by bandwidth \(lower bandwidth bridges sacrificed to open\-invitation buckets?\), by locale \(to be matched with a requesting user's geoip or something?\)
2\. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges \(and untrusted users have access to 1\)? More? Less?

Last weeks:
- Created a setup for extracting fingerprints from DLTS handshakes and analyzed the previous webrtc/dtls data sets from GitHub - kyle-macmillan/snowflake_fingerprintability. Found more fingerprints than presented in the original paper, but the fingerprints are not present in newer snowflake versions.
- Contacted Sean DuBois at Pion, he is very supporting of the project and happy to merge features related to anti-censorsip
- Started on a setup for collecting DTLS handshakes to be used for mimicking
- Exploring and planning features for anti-fingerprinting techniques to implement in the Pion lib.
Next weeks:
- Creating a setup for generating DTLS handshakes of web-browsers with selenium/playwright. This will hopefully generate common handshakes/fingerprints
