Peter Gutmann is a researcher in the Department of Computer Science at the University of Auckland working on design and analysis of cryptographic security architectures, security usability, and embedded systems security.  He helped write the popular PGP encryption package, has authored a number of papers and RFC’s on security and encryption including serving as the final editor of the world’s longest-running security RFC, RFC 8894, and is the author of the open source cryptlib security toolkit, the book “Cryptographic Security Architecture: Design and Verification”, and an upcoming book “Engineering Security”. In his spare time he pokes holes in whatever security systems and mechanisms catch his attention and grumbles about the lack of consideration of human factors in designing security systems.
