A Defense Against Replay Attacks on Chaumian Mixes
Georg Wittenburg – 2003
This paper describes the replay attack against traditional and channel-based Chaumian mixes and puts it into context with other attacks on anonymizing services. It then evaluates different possible approaches to a defense against said attack, concentrating on the question of efficiently recognizing potentially compromised messages within a channel-based cascade of mixes. Finally, an exemplary implementation of a solution is presented for the anonymizing cascade of mixes of the AN.ON project.
