Response To CNet Blogger Accusations

Recently, the researchers involved in this project were accused of potential wiretap, possible violation of human subject review and other issues by a graduate student who is also a blogger posting on the CNet news site.

On 24 July 2008, the University of Colorado conducted an internal review of the research methodologies and determined that no University of Colorado human subjects review was needed by this study, and that the study did not constitute research misconduct.

You can read more information about our response to these allegations at Response To Tor Study. The preceding is the private response of the researchers involved in this project, and not an official University of Colorado response to this topic. Please contact the University of Colorado press office for an official response.

Project Overview

We have been actively working on two projects within the realm of privacy and anonymity. The first has been a security analysis of Tor, a popular onion routing network used to anonymize TCP connections. Specifically, this work has examined how performance optimizations added to enhance the system's usability are fundamentally at odds with strong anonymity properties. The second project has focused on characterizing and modeling anonymous network usage, focusing on Tor, since it is the most widely used anonymous network. We provide a breakdown of application-level protocols within Tor, as well as an analysis of its performance at the circuit-level.
