摘要
针对现有访问控制模型不能完全满足协同产品开发访问控制需求的实际,在对访问控制策略进行分析研究的基础上,基于任务和角色访问控制模型,借鉴并扩充强制访问控制模型,提出一种面向协同产品开发的混合访问控制模型并给出了模型的定义和基本规则;然后以某型号飞机设计制造的协同产品开发系统的访问控制为例验证了模型的可行性。
The existing access control models can not completely meet the requirements of cooperative products development nowadays. Based on the task and role access control model and analyzing requirements of access control for cooperative product development,the paper refered to and expanded the mandatory access control strategy, a new mixed access control model was proposed, which faced the cooperative product development and gave the definition of the model and basic rules. The application on the access control of cooperative product development system for model aircraft design and manufacture shows the effectiveness of proposed method.
