Systems for Anonymous Communication
نویسندگان
چکیده
We present an overview of the field of anonymous communications, from its establishment in 1981 by David Chaum to today. Key systems are presented categorized according to their underlying principles: semitrusted relays, mix systems, remailers, robust & verifiable mixes, and onion routing systems. We include extended discussions of the threat models and usage models that different schemes provide, and the tradeoffs between the security properties offered and the communication characteristics different systems support.
