访问控制模型在煤质管理信息系统中的应用

Application of Access Control Model in Coal Quality Management Information System

论文以煤炭企业煤质管理信息系统为基础,利用基于角色的访问控制模型思想,根据对模型局限性分析,提出改进的访问控制模型,为用户指派角色,角色设定权限,实现用户和权限分离,降低授权复杂性。在进一步研究煤质管理信息系统的访问控制特点的基础上,设计和实现了访问控制系统,框架采用四层体系架构,保证了程序的高内聚低耦合,提高了系统安全性和扩展性。运行结果表明,该系统能够提高煤炭企业访问控制管理效率。

Based on coal quality management information system of coal enterprise, applying the idea of role - based access control model, the limitations of the model were analyzed, an improved model was proposed, which could assign role to user and set permission to different roles, realizing the separation of users and permissions, reducing the authorization complexity. Based on further research of access control features for coal quality management information system, the access control system was designed and implemented, applying the a four - layer architecture framework, ensuring high cohesion and low coupling of the program, and improving the security and scalability of the system. The operation results show that the system improves efficiency of coal enterprise access control management.
