Flash proxy
Flash proxy is a pluggable transport and proxy which runs in a web browser. Flash proxies are an Internet censorship circumvention tool which enables users to connect to the Tor anonymity network (amongst others) via a plethora of ephemeral browser-based proxy relays. The essential idea is that the IP addresses contingently used are changed faster than a censoring agency can detect, track, and block them. The Tor traffic is wrapped in a WebSocket format and disguised with an XOR cipher.[1]
Implementation
A free software[2] implementation of flash proxies is available. It uses JavaScript, WebSocket, and a Python implementation of the obfsproxy protocol,[3] and was crafted by the Security Project in Computer Security at Stanford University.[4] This work was supported by the Defense Advanced Research Project Agency (DARPA) and the Space and Naval Warfare Systems Center Pacific under Contract No. N66001-11-C-4022.[5]
