企业管理与控制网络之间的安全数据接口模型浅析

探讨了在工业企业网络的层次结构中建立管控数据接口的必要性，对接口按有无信息交换进行了分类，并针对有信息交换的接口提出了基础型和增强型两类安全的接口模型，以提高互联系统的实用性和安全性，最后把增强型模型应用到MES系统的网络框架设计中。

Analysis on Security Data Interface Models between Enterprise Management and Control Network

The necessity of establishing the data control interface in industrial enterprise network hierarchy is discussed. The interfaces are classified according to whether they have message switching or not. For the interface having message switching, the two security interface model of base and enhancement type are proposed to improve the practicability and security of the interconnected system. Finally, the enhancement model is applied to the design of MES internet architecture.
