基于任务和角色的学习流访问控制模型

Access Control Model of Learning Flow Based on Task and Role

根据基于学习流的网络学习平台的访问控制需求,提出一种基于任务和角色的学习流访问控制模型,并描述模型中用户、角色、任务、权限等要素和它们之间的指派关系以及相关的约束规则。该模型根据学习流的具体要求,将权限委派给任务,任务分配给角色,角色指派给用户,用户通过角色来获取相应权限,提高了数据访问的安全性。最后给出模型的实现框架以及执行流程。

According to the needs of access control based on network learning platform of learning flow, the thesis puts forward a kind of access control model of learning flow based on task and role, and describes the assignment relations between users, roles, tasks, permissions and other elements, and also the relevant constraint rules. According to the specific requirements of learning flow, the model assigns permissions to tasks, tasks to roles, roles to users. The users obtain the corresponding permissions through roles, which improves the security of data access. Finally, the thesis offers a framework of implementation and execution process of the model.
