The Internet enables access to a wide variety of information sources; many countries and organizations, however, try to restrict such access for political and social reasons. People whose access has been censored make use of a variety of circumvention technologies to find the information they need; in turn, the censors use increasingly sophisticated tools to render these technologies ineffective.

One of the more powerful tools censors use are blocking IP addresses that are used for circumvention. I will describe two circumvention approaches that are immune to this approach: CensorSpoofer, which fakes the source address of its traffic in order to avoid detection, and Cirripede, which can be deployed within the Internet routing infrastructure to surreptitiously capture and redirects a connection to a covert destination. I will discuss the design of both systems as well as some remaining challenges to their deployment.
