Anonymous communication (AC) protocols such as the widely used Tor network have been designed to provide anonymity over the Internet to their participating users. While AC protocols have been the subject of several security and anonymity analyses in

For anonymous communication networks (ACNs), Das et al. recently confirmed a long-suspected trilemma result that ACNs cannot achieve strong anonymity, low latency overhead and low bandwidth overhead at the same time. Our paper emanates from the caref

The authors introduce delegatable functional signatures (DFS) which support the delegation of signing capabilities to another party, called the evaluator, with respect to a functionality F . In a DFS, the signer of a message can choose an evaluator,

In this paper, we present a rigorous methodology for quantifying the anonymity provided by Tor against a variety of structural attacks, i.e., adversaries that corrupt Tor nodes and thereby perform eavesdropping attacks to deanonymize Tor users. First

Computing differential privacy guarantees is an important task for a wide variety of applications. The tighter the guarantees are, the more difficult it seems to be to compute them: naive bounds are simple additions, whereas modern composition theore

Many applications, such as anonymous communication systems, privacy-enhancing database queries, or privacy-enhancing machine-learning methods, require robust guarantees under thousands and sometimes millions of observations. The notion of r-fold appr

Recently, the live-monitor MATor for formally analyzing user anonymity within the Tor network has been proposed (CCS'14). However, this monitor only considers adversaries that compromise part of the Tor network itself, not Internet infrastructural ad
