工作流管理系统安全模型

Security model of workflow management system

以现有安全工作流模型为基础 ,提出了基于任务的授权控制思想 ,阐述了任务和任务实例之间的关系 ,进一步解释了任务权限指派和实例权限指派之间的区别和联系 ,并且针对上述模型进行了一些合理的改造 ,构造了一个工作流管理系统的安全模型 .

Based on a series of models for security workflow put forward by Ravi Sandhu, the idea of task-based access control was illustrated, and the relationship between task and task instance was explained. The association and difference between task permission assignment and instance permission assignment were interpreted. Some rational improvements to these models were carried out, and a security model was constructed for workflow management system.
