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…
Understanding the Effects of Real-World Behavior in Statistical Disclosure Attacks
Simon Oya, Carmela Troncoso, Fernando Pérez-González
High-latency anonymous communication systems prevent passive eavesdroppers from inferring communicating partners with certainty. However, disclosure attacks allow an adversary to r…
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…
MPEG-2 Prediction Residue Analysis
David Vázquez-Padín, Fernando Pérez-González
Based on the use of synthetic signals and autoregressive models to characterize temporal dependencies and inter prediction processes, a semi-analytic model is built to explain the…
Rethinking Location Privacy for Unknown Mobility Behaviors
Simon Oya, Carmela Troncoso, Fernando Pérez-González
Location Privacy-Preserving Mechanisms (LPPMs) in the literature largely consider that users' data available for training wholly characterizes their mobility patterns. Thus, they h…
