We analyze the anonymity provided by continuous mixnets (eg, Loopix) when messages
with different latency requirements are sent through the same network. The anonymity …

Traffic analysis attacks can counteract end-to-end encryption and use leaked
communication metadata to reveal information about communicating parties. With an ever …

We propose a method to optimally select mix network parameters for a given deployment
context and adversarial model. Our method considers both worstcase and average-case …

This work formally analyzes the anonymity guarantees of continuous stop-and-go mixnets
and attempts to answer the titular question. Existing mixnet based anonymous …

Anonymous communication systems such as mix networks achieve anonymity at the
expense of latency that is introduced to alter the flow of packets and hinder their tracing. A …

Mixnets are a fundamental privacy enhancing technology in the context of anonymous
communication that have been extensively studied in terms of a Global passive Adversary …

Mix networks (mixnets) enhance anonymity by routing client messages through multiple
hops, intentionally delaying or reordering these messages to ensure unlinkability. However …

It is well known that pseudonymity in blockchains such as Bitcoin or Ethereum does not
really hide the identity of the author of a payment. A number of attacks have been …

Anonymity in Web and Internet communication is a widely investigated problem. Mixnets
represent certainly the most concrete and effective approach to achieving the above goal. In …
