Research Direction and Trust Negotiation

Automated trust negotiation is a new approach to establishing trust between strangers through the disclosure of digital credentials.  Since credentials may be sensitive, access control policies can be used to control the disclosure of the credentials themselves.  There are a number of open research problems in this area, including secure protocol design, privacy, and usability.

The Internet Security Research Lab at BYU is a leader in this new research area.  In this talk, I will highlight the recent research that BYU students are conducting, including a radical new approach to trust negotiation known as hidden credentials that provides stronger privacy guarantees than prior approaches to trust negotiation.


Kent Seamons is an Assistant Professor in the Computer Science Department at Brigham Young University and is the Director of the Internet Security Research Lab. His current research emphasis is in authentication and authorization in open systems.  He has published 35 articles in the areas of trust negotiation, information retrieval, and parallel I/O. Prior to joining the faculty at BYU, Dr. Seamons was the Principal Investigator on several DARPA-sponsored research projects at the IBM Transarc Lab in Pittsburgh, PA where he was a co-inventor of trust negotiation. He received his PhD in Computer Science from the University of Illinois at Urbana-Champaign.
