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
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
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
"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
years. Currently he is a Tor Browser developer.
