Anonymity and Censorship Resistance


First slide of cl08security-anon.pdf


Cambridge Part II Security


The extent of Internet censorship is rapidly increasing, and along with it interest in censorship resistance technologies. This talk will discuss some of the motivations and targets of censorship, and describe the technologies and social controls used to implement blocking. Anonymous communication systems will then be introduced, as well as how they can help provide censorship resistance. One such system, Tor, will be described in detail, and an overview of the operation of two other systems – Freenet and Psiphon – will be given.
