基于角色的水利行业监理信息系统访问控制优化模型

Optimization of role-based access control model for monitoring information system of water conservancy industry

分析水利行业监理信息系统访问控制现状和存在的问题,在RBAC模型及其扩展模型的基础上,提出了主体与角色二次定义的方法,构建了基于角色的访问控制的优化模型,并应用该模型对某水利行业监理企业进行优化设计。结果表明,该模型增加了RBAC模型授权的柔性,从而较好地解决了水利行业监理企业信息系统的授权问题。

The current situations of access control of monitoring information system of water conservancy industry as well as the existing problems are analyzed.Based on the RBAC models and their extended models,a method for the secondary definition of the main body and the roles is put forward. An optimization model for role-based access control is established. The model is applied to the optimization design of a construction supervision enterprise of water conservancy industry. The results show that the proposed model increases the flexibility of authorization of the RBAC model so as to satisfactorily solve the authorization problem of the monitoring information system of the supervision enterprise of water conservancy industry.
