Abstract
In workflow environments, access control is an important issue of security. Especially, a suitable access control model to meet the special secure requirements is needed. In this paper, we present a formal model, called RTFW, which allows for some ubiquitous problems in workflow environments, such as separation of duty and dynamic authorization, combining the notions of role– based access control (RBAC) and task- based access control (TBAC) models. Furthermore, we describe how to design and implement its prototype system and discuss some key issues and challenges.
