Group-Centric Secure Information Sharing
Prof. Ravi Sandhu, University of Texas at San Antonio
This talk will give an overview of the concept of group-centric secure information sharing, which is distinguished from traditional dissemination-centric sharing. It will describe policy and enforcement models developed for this purpose, and identify research challenges in this arena. The core metaphor behind groups-centric sharing is a meeting room wherein users and information are brought together for some larger purpose. Agility in sharing requires that such virtual meeting rooms be established and go through their life cycle as driven by end users rather than IT administrators. Security requires that the sharing conform with organizational requirements and policies. The group-centric paradigm is a promising approach to reconcile these conflicting objectives.
