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 compromise Tor nodes and thereby perform eavesdropping attacks to deanonymize Tor users. First, we provide an algorithmic approach for computing the anonymity impact of such structural attacks against Tor. The algorithm is parametric in t...
This thesis presents information theoretic anonymity metrics and various analysis of anonymous communication nodes. Our contributions are a step towards the understanding of anonymity properties and the development of robust anonymous communications. Anonymous communications are an essential building block for privacy-enhanced applications, as the data available at the communication layer may l...
We present a powerful and flexible method for automatically checking anonymity in a possibilistic general-purpose process algebraic verification toolset. We propose new definitions of a choice anonymity degree and a player anonymity degree, to quantify the precision with which an intruder is able to single out the true originator of a given event or to associate the right event to a given proto...
Currently known basic anonymity techniques depend on identity veri cation. If veri cation of user identities is not possible due to the related management overhead or a general lack of information (e.g. on the Internet), an adversary can participate several times in a communication relationship and observe the honest users. In this paper we focus on the problem of providing anonymity without id...
