%X This paper proposed a workflow authorization model based on RBAC(Role-Based Access Control) for collaborative design system.Different from traditional access control authorization models,this model provided the notion of temporal-spatial permission which represents the fact that can only perform certain operation on a task for a certain time interval and a certain spatial range of Internet/Intranet,namely the workflow authorization based on RBAC for collaborative design system not only relates with time,but also relates with Internet/Intranet address.It can not only ensure that only authorized users could execute a task,but also ensure that the authorization flow is synchronized with workflow and the dynamic change of spatial range of Internet/Intranet address.
