Access Control Models and Mechanisms

In today's generation of information technology, it is critical to manage large-scale networks and distributed systems efficiently and securely. We are motivated to provide novel access control solutions that fulfill the needs of heterogeneous applications and environments. Our research and development focus on leading edge issues of access control, including generic access control models, methodologies, mechanisms, security policies, and innovative access control applications.

Identity and Privacy Management

The Internet is now a prime vehicle for business, community, and personal interactions. The notion of identity is the important component of this vehicle. However, user's identities are scattered across isolated Internet sites and various security and privacy issues of identity have been increased. In this research area we have investigated security and privacy issues of identity management.
