一种基于活动序列的协同设计访问控制模型
Activity sequence based access control model in collaborative design
摘要
Abstract
To assure activity based dynamic assignment and retrieve of cooperative permission in multi-user environment,this paper proposed an activity sequence based access control model, and provided CPNs based modeling and analyzing issues. In this model, it divided the shared cooperative document and view space according to the sequence of interdependent activities, and associated the cooperative activities with the assignment and retrieve of role. Therefore, it solved the problem of authorized users with persistent permissions to specific object in traditional access control. Finally, gave an example of applying cooperative roles to indicate how to implement the dynamic assignment and retrieve of cooperative permission.关键词
