摘要
异地协同设计是典型的多用户参与的多任务系统 ,用户之间存在大量的协作过程。安全性是协同设计实施的关键问题。基于广域网协同设计系统的特点 ,提出了基于角色的多层强制访问控制和基于信息流的访问控制相结合的安全模型 。
Concurrent design environment is a multi-user,multi-task involved system,which is consisted of lots of collaborative processes.A resource access control mechanism is needed in such a sophisticated system.Based on the role-based mandatory model and information flow model,a combined security model is presented.Also,a control rule under this model is discussed.
