Making Email Dark

DEF CON 23

Presented by: Chris Brown, Ladar Levison, Fred Nixon
Date: Friday August 07, 2015
Time: 00:00 - 00:00
Location:

This talk will focus on the Dark Internet Mail Environment (DIME), a standards based, collaborative effort to create an elegant technical solution which is capable of protecting the privacy of email. DIME is focused on making the end-to-end encryption of email messages automatic, provides for message confidentiality, author verification, and minimizes the leakage of metadata. The DIME standards dramatically reduce the amount of trust individual users must place in service providers. The new standards, which we hope will someday succeed OpenPGP, have been designed to resist manipulation by advanced persistent threats. During this short presentation, we will provide a compressed discussion of the DIME standards, followed by a project update, where we hope to showcase the DIME implementation effort.br />

Ladar Levison

Ladar Levison is the Owner and Operator of Lavabit, LLC, an email service founded in 2004 (and originally named Nerdshack), Lavabit has always been focused on protecting the privacy of its user's communications. Levison created Lavabit because he believes that privacy is a fundamental, inalienable right, and a prerequisite for afunctioning, free and fair democratic society. This led Lavabit to reach, at its peak, over 410,000 users. Then, on August 8, 2013, and in response to a court decision which required Lavabit to surrender its TLS private key, Levison made the bold decision to suspend operations, and refuse to remain silent, and "complicit in crimes against the American people." Since then Levison has been vigorously defending the right to speak freely, and privately on the Internet. As the principal force behind the Dark Mail Initiative, Levison has also been working on a technical solution for the problem of email privacy.

Fred Nixon

Fred Nixon is a developer, based in Atlanta, and working to implement the Dark Internet Mail Environment. Fred has worked for Mindspring, Earthlink, and General Electric in Research and Development, creating scalable, distributed systems for communications and core ISP services. He is an advocate for speech and privacy rights, and the technology to support those rights for everyone. STDs are the least of your worries when Cyber Cancer Prognosis is imminent Crypto and privacy are BIG concerns when dealing with any type of threat but when dealing with STDs (we refuse to acknowledge APT - anyone who mentions advanced persistent threats shall be thrown out of the talk ;>)
