Internet Censorship and Control Papers

Hal Roberts and Steven J. Murdoch of the University of Cambridge Computer Laboratory have edited a collection of papers on Internet Censorship and Control that are now available online as an open access collection at They write, "The Internet is and has always been a space where participants battle for control. The two core protocols that define the Internet – TCP and IP – are both designed to allow separate networks to connect to each other easily, so that networks that differ not only in hardware implementation (wired vs. satellite vs. radio networks) but also in their politics of control (consumer vs. research vs. military networks) can interoperate easily. It is a feature of the Internet, not a bug, that China – with its extensive, explicit censorship infrastructure – can interact with the rest of the Internet.

"In the following collection, published as an open access collection here and as well in a special issue of IEEE Internet Computing, we present five peer reviewed papers on the topic of Internet censorship and control... These papers make it clear that there is no global consensus on what mechanisms of control are best suited for managing conflicts on the Internet, just as there is none for other fields of human endeavour. That said, there is optimism that with vigilance and continuing efforts to maintain transparency the Internet can stay as a force for increasing freedom than a tool for more efficient repression." The collection includes: Introduction to Special Issue on Internet Censorship and Control by Murdoch and Roberts; Not by Technical Means Alone: The Multidisciplinary Challenge of Studying Information Controls by Masashi Crete-Nishihata, Ronald J. Deibert, and Adam Senft; Assessing Censorship on Microblogs in China: Discriminatory Keyword Analysis and Impact Evaluation of the 'Real Name Registration' Policy by King-wa Fu, Chung-hong Chan and Michael Chau; Censorship V3.1 by Derek E. Bambauer; Anarchy, State, or Utopia? Checks and Balances of Power in Internet Governance by Christopher M. Riley; Trust Darknet: Control and Compromise in the Internet's Certificate Authority Model by Steven B. Roosa and Stephen Schultze.
