We were thinking of getting people to connect to a censored network, e.g by providing a router that censors in different way; and try to access the internet or some sites or something. We would need some advice/help to set something like this up -- Pili & Gus - Source code from 2017 experiment (few hundred users, Windows only, simulated censorship with a local firewall, used an instrumented Tor Browser to record mouse clicks): - https://github.com/lindanlee/PETS2017-paper - see experiment/firewall.bat and experiment/gen-firewall - see the screenrecording directory - see the session/pre/videos directory for videos and detailed notes of a pre-study - see the setup directory for other setup notes (don't remember what exactly) - paper: https://censorbib.nymity.ch/#Lee2017a - Source code from 2015 experiment (5 users, one on one, no censorship, just browser usability): - git clone https://www.bamsoftware.com/repo.eecs.berkeley.edu/tor-ux.git/ (see README and tasks.html) - videos: https://people.torproject.org/~dcf/uxsprint2015/ - blog post: https://blog.torproject.org/blog/ux-sprint-2015-wrapup == Actions == == Interesting links == NDSS 2020 PDFs are online https://www.ndss-symposium.org/ndss-program/2020-program/ "Detecting Probe-resistant Proxies" https://www.ndss-symposium.org/ndss-paper/detecting-probe-resistant-proxies/ https://sfrolov.io/papers/ndss20-frolov.pdf "Decentralized Control: A Case Study of Russia" https://www.ndss-symposium.org/ndss-paper/decentralized-control-a-case-study... https://censoredplanet.org/russia https://github.com/net4people/bbs/issues/20 "Measuring the Deployment of Network Censorship Filters at Global Scale" https://www.ndss-symposium.org/ndss-paper/measuring-the-deployment-of-networ...
