Three types of policies were studied including qualification, requirements and substitution policies which can not handle complex role resolution such as Separation of Roles and Binding of Roles, and several exception situations, such as Role Delegation and Role Unavailable. From the perspective of project-oriented workflow, a project and its sub-projects can be under the charge of teams (or virtual teams). The teams should satisfy the role resolution of the projects managed by the team. To support the above requirements, based on team-enabled organization model, this paper extended HP’s policy language to support the role resolution in project-oriented workflow, and provided its modeling and enforcement mechanism.展开更多

This paper intends to cast light on the management of project-oriented workflow. A comprehensive authorization model is proposed from the perspective of project management. In this model, the concept of activity decomposition and team is introduced, which improves the security of conventional role-based access control. Furthermore, policy is provided to define the static and dynamic constraints such as Separation of Duty (SoD). Validity of constraints is proposed to provide a fine-grained assignment, which improves the performance of policy management. The model is applicable not only to project-oriented workflow applications but also to other teamwork environments such as virtual enterprise.展开更多
