On Thursday, November 16th at 3pm, the Internet Governance Lab Roundtable Speaker Series will host Dr. Eric Novotny of American University’s School of International Service for a discussion on emerging information communication technologies designed to circumvent censorship and their impacts on freedom of expression and privacy online.

The event will take place in SIS 260 at AU’s School of International Service.

As Dr. Novotny explains:

Censorship on the world wide web by governments continues to be a barrier and a threat to freedom of speech, ideas, and information. Regimes use various techniques such as IP blocking, DNS poisoning, and DPI to interfere with traffic among clients and servers. Almost all contemporary, operational circumvention technologies rely on network access and routing through proxies or bridges to obfuscate traffic between their client and an intended host.  Increasing capabilities are surfacing that will challenge the utility of such end-to-end proxy techniques.  Refraction routing is an emerging technique that takes an end-to-middle approach to the problem by building anti-censorship into the core of the Internet architecture.  This discussion introduces the general problem of circumvention technology and compares various ways that refraction routing can be implemented on the world wide web.  These techniques may provide significantly stronger resistance to common forms of blocking by repressive governments and also provide collateral cybersecurity benefits.  One method for implementing refraction routing has already been successfully field tested to overcome blocking and will be discussed.

All are welcome and we look forward to a lively discussion of the topic following Dr. Novotny’s presentation.
