Design of a blocking-resistant anonymity system (draft)

作者:Roger Dingledine,Nick Mathewson


摘要:Internet censorship is on the rise as websites around the world are increasingly blocked by government-level firewalls. Although popular anonymizing networks like Tor were originally designed to keep attackers from tracing people’s activities, many people are also using them to evade local censorship. But if the censor simply denies access to the Tor network itself, blocked users can no longer benefit from the security Tor offers. Here we describe a design that builds upon the current Tor network to provide an anonymizing network that resists blocking by government-level attackers.
