GFWeb
Large-scale, continuous discovery of the domain blocklists the Great Firewall uses to censor Web access over HTTP and HTTPS.
Projects
Live measurement systems and public datasets from my group and my collaborations. Each links to the paper describing the method behind it.
GFWatch
Longitudinal measurement of the Great Firewall’s DNS censorship, reporting which domains are poisoned and which forged addresses are injected.
I2P Metrics
Measurement of the I2P anonymity network: relay populations, reachability, and where access to it is blocked.
I2P Reseed Server
A reseed server that helps new I2P clients bootstrap into the network from places where the usual reseed servers are blocked.
Domain Name Privacy
An ongoing line of work on what DNS-over-TLS, DNS-over-HTTPS and Encrypted Client Hello actually hide, how reachable those protocols are around the world, and what still leaks once the domain name is encrypted.
