Moxie Marlinspike is a fellow at the Institute for Disruptive Studies and a co-founder of Whisper Systems. He has more than fifteen years of experience attacking networks. He is the author of sslsniff, used by the MD5 hash collion team to deploy their rogue CA cert, and sslstrip, which implements Moxie's deadly "stripping" technique for rendering communication insecure. He was the chief technology officer and co-founder of Whisper Systems, acquired by Twitter in 2011. Together with Trevor Perrin, Moxie created TACK (Trust Assertions For Certificate Keys), an IETF draft for a dynamically activated public key pinning framework that provides a layer of indirection away from Certificate Authorities, but provides full backwards compatible with existing CA certificates, and does not require sites to modify their existing certificate chains. His tools have been featured in many publications, including Hacking Exposed, Forbes, The Wall Street Journal, The New York Times, and Security Focus as well as on international TV. Additionally, he runs a cloud-based WPA cracking service, manages the GoogleSharing targeted anonymity service, and is the author of the sailing film Hold Fast.
Trevor Perrin is an independent consultant who designs and reviews
cryptographic systems. Recent projects include public-key pinning
(TACK), key agreement (TripleDH), asynchronous messaging (Axolotl
Ratchet), and password-authenticated key exchange.
Joseph Lorenzo Hall, PhD is the Chief Technologist at the Center for Democracy & Technology, a Washington, DC-based non-profit organization dedicated to ensuring the Internet remains free, open and innovative. Prior to joining CDT in late 2012, Hall was a postdoctoral research fellow with Helen Nissenbaum at New York University, Ed Felten at Princeton University and Deirdre Mulligan at University of California, Berkeley.
Hall’s current work focuses on policy mechanisms that promote trustworthiness and transparency in information systems, as core functions of society and government become networked and computerized. Hall’s work at CDT is split between Consumer Privacy, Health Privacy and National Security. Hall received his PhD in information systems from the UC Berkeley School of Information. His PhD thesis used electronic voting as a critical case study in digital government transparency. Hall holds master’s degrees in astrophysics and information systems from UC Berkeley and was a founding member of the National Science Foundation’s ACCURATE Center. He has served as an expert on independent teams invited by the States of California, Ohio and Maryland to analyze legal, privacy, security, usability and economic aspects of voting systems, and currently serves on the board for VerifiedVoting.org. In 2012, Hall received the John Gideon Memorial Award from the Election Verification Network for contributions to election verification. He tweets on privacy, security and technology as @JoeBeOne.
Matthew D. Green, PhD is a professor of computer science at Johns Hopkins University. He teaches applied cryptography and builds secure systems. Green trained under Susan Hohenberger and Avi Rubin, and his research includes techniques for privacy-enhanced information storage, anonymous payment systems, and bilinear map-based cryptography. Green formerly served as a senior research staff member at AT&T Labs. Together with Kenneth White, he co-founded the TrueCrypt audit project, a community-driven initiative to conduct the first comprehensive cryptanalysis and public security audit of the widely used TrueCrypt encryption software.
