摘要
A family of RBAC-based workflow authorization models, called RWAM, areproposed RWAM consists of a basic model and other models constructed from the basic model. The basicmodel provides the notion of temporal permission which means that a user can perform certainoperation on a task only for a time interval, this not only ensure that only authorized users couldexecute a task but also ensure that the authorization flow is synchronised with workflow. The twoadvance models of RWAM deal with role hierarchy and constraints respectively RWAM ranges from simpleto complex and provides a general reference model for other researches and developments of suchareah.
