Abstract

The secure interaction between two or more administrative domains is a major concern. IRBAC2000 is a model that quickly establishes a flexible policy for dynamic role translation from foreign domains to local. A-IRBAC2000 mode utilizes RBAC to manage dynamic role translation between foreign and local domains. We will see that these mechanisms have significant shortcomings. We propose an improved Administrative Usage Control model named AUCON to overcome the weakness of previous models. AUCON provides administrates userrole assignment for local and foreign domain with unified method. It provides flexible enough mechanism to distinguish users of foreign and local domain and can enforce more strict control for foreign user. While retaining the advantage of traditional RBAC model, AUCON model is being implemented in experiment system.
