Effectiveness and detection of denial-of-service attacks in tor
Norman Danner, Sam Defabbia-Kane, Danny Krizanc, Marc Liberatore
Article No.: 11
DOI: 10.1145/2382448.2382449

Tor is one of the more popular systems for anonymizing near-real-time communications on the Internet. Borisov et al. [2007] proposed a denial-of-service-based attack on Tor (and related systems) that significantly increases the probability of...

Adversarial stylometry: Circumventing authorship recognition to preserve privacy and anonymity
Michael Brennan, Sadia Afroz, Rachel Greenstadt

Probabilistic analysis of onion routing in a black-box model
Joan Feigenbaum, Aaron Johnson, Paul Syverson
Article No.: 14
DOI: 10.1145/2382448.2382452

We perform a probabilistic analysis of onion routing. The analysis is presented in a black-box model of anonymous communication in the Universally Composable (UC) framework that abstracts the essential properties of onion routing in the presence...
