摘要：

A workflow authorization model based on credentials was proposesed. It can nicely satisfy the features that workflows in actual application should satisfying. This model uses access control list based on task state which nicely ensure synchronizing authorization flow with workflow; specifies authorization policy not only based on user identifiers but also based on user qualifications and characteristics; defines a set of constraint rules for a task and seek the eligible users to execute the task according to the type of each constraint rule which realize dynamic separation of duty; and realizes the access granularity of authorization ranging from objects to specific parts of objects which ensure the least privilege constraints much more better.
