摘要
网上并行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。安全性是并行设计实施的关键问题。本文基于广域网并行设计系统的特点 ,提出了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 ,讨论了该模型下的安全策略。
Concurrent design environment is a multi-user , multi-task system, which consists of lots of collaborative processes. A resou rce access control mechanism is needed in such a sophisticated system. Based on the mandatory model and information flow model, a combined security model is pre sented in this paper. Also, a control rule under this model is discussed.
