My name is Chang Lan. I am a fourth-year computer science undergraduate student at Tsinghua University, China, and will be a grad student at Berkeley focusing on networking in this fall. I have been a big fan of the Tor Project for years, as I am actually using it for circumventing the censorship. I look forward to contributing to this project as well.

Specifically, I would like to improve current obfsproxy implementation, so that it can resist active censors from scanning its presence. To my knowledge, obfsproxy should avoid responding to handshake requests from clients unless clients have the server's key, which shall be obtained from BridgeDB. I am a newbie at Tor development though, and it would be great if there is anyone willing to talk further with me on this topic.
