Abstract. Mix networks are a popular mechanism for anonymous Internet communications. By routing IP traffic through an overlay chain of mixes, they aim to hide the relationship bet...
A mix is a communication proxy that hides the relationship between incoming and outgoing messages. Routing traffic through a path of mixes is a powerful tool for providing privacy....
Low latency anonymous network systems, such as Tor, were considered secure against timing attacks when the threat model does not include a global adversary. In this threat model t...
Many proposed low-latency anonymous communication systems have used various flow transformations such as traffic padding, adding cover traffic (or bogus packets), packet droppi...
In this paper, we introduce a novel metric that can quantitatively measure the practical effectiveness (i.e. anonymity) of all anonymous networks in the presence of timing attack....
