Where Theory Meets Practice for Privacy Enhancing Technologies

Chelsea Komlo, HashiCorp

July 9, 2018 2:30pm, in DC 1304


Privacy Enhancing Technology communities rely on the research community for help designing and validating protocols, finding potential attack vectors, and applying new technological innovations to existing protocols. However, while the research community has made significant progress studying projects such as Tor, the number of research outcomes that have actually been incorporated into privacy enhancing technologies such as The Tor Project is lower than the number of feasible and useful research outcomes. In this talk, we will examine why good research ideas can fail to be incorporated into privacy enhancing technologies such as Tor, and how maintainers and developers of such projects can work with researchers to ensure that good ideas are fully incorporated. We will look at where and why this process breaks down, and what steps are needed to ensure a complete transition from theory to practice for privacy enhancing technologies.


Chelsea Komlo is a software/security engineer with a focus on distributed systems, open source software, and applied cryptography. She has worked across a variety of open source projects, and is a core Tor developer. Chelsea has lead cross-functional and cross-regional security initiatives and held trainings in both English and Spanish on operational security and privacy issues. Chelsea currently works at HashiCorp and is part of a team developing an open-source distributed scheduler.

"Where's Waldo?" - Privacy in the age of Internet-connected mobile technology

Matthew Finkel, The Tor Project

July 10, 2018 2:30pm, in DC 1304


There are hundreds of millions of new "smart" mobile device users every year, but the mobile ecosystem and infrastructure are designed and built for optimizing convenience, not protecting the privacy of the user. From a design flaw in the Internet Protocol to an abundence of physical sensors, a mobile device may tell a third-party more information than the user intended or wanted. This talk will look at IPv6 and its current state on mobile networks, then we'll describe some of the information our useful pocket computers collect and send. We'll conclude with some additional information about how a mobile phone's general physical location is found.


Matthew Finkel hacks on privacy-preserving technology most days. He helps train activists, journalists, and at-risk groups on digital and operational security. He has worked with The Tor Project during the day, and at night, contributing to code and helping the community over the last few years. Currently he is a Tor Browser developer.
