摘　　要：当前电力监控系统安全接入网关时,存在数据传输安全性差、数据传输效率低和网关机密性差的问题。提出基于SM算法的电力监控系统安全接入网关设计方法,通过Android手机客户端、模拟PROFIBUS-DP设备的PC机、4G通信模块和网关四个部分构成硬件结构,密码防护层、安全协议层和数据通信层组成软件部分,并将SM算法应用在安全协议层中,过滤非法网络报文,避免非法网络报文通过安全接入网关进入主站中。实验结果表明,所提方法的数据传输安全性高、数据传输效率高、网关机密性高。There are problems of poor data transmission security, low data transmission efficiency and poor gateway confidentiality when the power monitoring system accesses the gateway. A design method for the secure access gateway of the power monitoring system based on the SM algorithm is proposed. The hardware structure is constituted by the four parts of the Android mobile phone client, the PC that simulates the PROFIBUS-DP device, the 4G communication module and the gateway. The software part is consist of the password protection layer, the security protocol layer and the data communication layer, and the SM algorithm is applied in the security protocol layer to filter illegal network messages and prevent illegal network messages from being safely accessed. The gateway enters the master station. Experimental results show that the proposed method has high data transmission security, high data transmission efficiency, and high gateway confidentiality.
