Using obfuscated proxies and pluggable transports
Censors were still able to block access to Tor; the technique was to identify the traffic pat-
terns generated by Tor and block the connection. In 2010, Jacob Appelbaum and Nick
Mathewson of the Tor Project suggested a method to obfuscate the Tor traffic between the
client and the bridge in order to thwart deep packet inspection. As the obfuscation mechan-
ism might need to change, and has changed in fact, the Tor Project wanted a generic pro-
tocol to allow different obfuscated proxies to run. This abstraction was known as
plug-
gable transport
.
In this chapter, we will set up your BBB to run as a Tor bridge, running an obfuscated
proxy, using the obfs3 pluggable transport.
