Carlisle Adams is a Professor in the School of Electrical Engineering and Computer Science (EECS) at University of Ottawa. Prior to his academic appointment in 2003, he worked for 13 years in industry (Nortel, Entrust) in the design and international standardization of a variety of cryptographic and security technologies for the Internet. Dr. Adams' research interests include all aspects of applied cryptography and security. Particular areas of interest and technical contributions include the design and analysis of symmetric encryption algorithms (including the CAST family of symmetric ciphers), the design of large-scale infrastructures for authentication (including secure protocols for authentication and certificate management in Public Key Infrastructure (PKI) environments), and comprehensive architectures and policy languages for access control in electronic networks (including X.509 attribute certificates and the XACML policy language).
Dr. Adams has maintained a long-standing interest in the creation of effective techniques to preserve and enhance privacy on the Internet. His contributions in this area include techniques to add delegation, non-transferability, and multi-show to Digital Credentials, architectures to enforce privacy in web-browsing environments, and mechanisms to add privacy to location-based services and blockchains. He was Co-Chair of the international conference Selected Areas in Cryptography (1997, 1999, 2007, and 2017), and was General Chair of the 7th International Privacy Enhancing Technologies Symposium (2007).
He lives in Ottawa with his wife and children and enjoys music, good food, and classic movies (old and new).
