PRES-A Practical Flexible RBAC Workflow System

摘要

Web-based workflow can be used to facilitate enterprise business process while the security and flexibility are two of the most important aspects in electronic business system. RBAC is regarded as a neutral policy and has been the most popular secure model in recent years. The flexible RBAC workflow model (FRWM) has been proposed recently. It has encapsulated RBAC and workflow together considering both security and flexibility features. In this paper the enforcement of FRWM is introduced. We also present the design and implementation of a practical system for Property Right Exchange (PRES) based on FRWM, in which the flexibility of workflow can be reached through definition and execution while considering the" security with RBAC.
