zksk: A Library for Composable Zero-Knowledge Proofs
Wouter Lueks, Bogdan Kulynych, Jules Fasquelle +2
Zero-knowledge proofs are an essential building block in many privacy-preserving systems. However, implementing these proofs is tedious and error-prone. In this paper, we present z…
Filter Design for Delay-Based Anonymous Communications
Simon Oya, Fernando Pérez-González, Carmela Troncoso
In this work, we address the problem of designing delay-based anonymous communication systems. We consider a timed mix where an eavesdropper wants to learn the communication patter…
A Least Squares Approach to the Static Traffic Analysis of High-Latency Anonymous Communication Systems
Fernando Pérez-González, Carmela Troncoso, Simon Oya
Mixes, relaying routers that hide the relation between incoming and outgoing messages, are the main building block of high-latency anonymous communication networks. A number of so-…
Meet the Family of Statistical Disclosure Attacks
Simon Oya, Carmela Troncoso, Fernando Pérez-González
Disclosure attacks aim at revealing communication patterns in anonymous communication systems, such as conversation partners or frequency. In this paper, we propose a framework to…
Encrypted DNS --> Privacy? A Traffic Analysis Perspective
Sandra Siby, Marc Juarez, Claudia Diaz +2
Virtually every connection to an Internet service is preceded by a DNS lookup which is performed without any traffic-level protection, thus enabling manipulation, redirection, surv…
Disparate Vulnerability to Membership Inference Attacks
Bogdan Kulynych, Mohammad Yaghini, Giovanni Cherubin +2
A membership inference attack (MIA) against a machine-learning model enables an attacker to determine whether a given data record was part of the model's training data or not. In t…
