面向信息安全的并行设计系统

安全性是异地并行设计系统实施的关键问题。基于广域网的并行设计系统是多用户多任务的分布式系统 ,用户之间存在大量的协作过程 ,访问控制问题显得尤为重要。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信息安全模型 ,并讨论了该模型在并行设计系统中的应用

A Security-Oriented Concurrent Design System

Security is the key to the implementation of a distributed concurrent design system. The internet-based concurrent design environment is a multi-user, multi-task, which is consisted of lots of collaborative processes. Thus the issue of access control is very important to such a sophisticated system. Based on the role-based mandatory model and information flow model, the paper presents a combined security model, and discusses a system security scheme under this model.
