摘要
为了提高电力自动化系统安全性,文章基于用户访问控制(RBAC)模型,将用户可信度与RBAC结合并运用到电力调度自动化系统中。文章从RBAC角度引入了可信度的计算框架和算法,并将两者结合;接着通过算法检测来验证软件算法的可用性;最后检测整个系统的工作状态。结果显示可信度计算具有较好的适用性。文章最后得出结论 :基于信任度与用户控制结合的控制,具有提高电力调度自动化系统的安全稳定性的潜力。
In order to improve the security of power automation system, based on the user access control （RBAC） model, this paper combines the user credibility with RBAC and it is be applied in the automation system of power dispatching. This paper introduces the credibility of the RBAC framework and algorithm, and the combination of the two; and then through the algorithm to verify the availability of the software algorithm; finally, the detection of the whole system. The results show that the reliability calculation has good applicability. At last, the conclusion is drawn that the control based on the trust degree and the user control has the potential to improve the security and stability of the power dispatching automation system.
