国产密码在水利自动控制系统中的应用

Application of domestic encryption in water conservancy automatic control system

水利自动化控制系统中使用最广泛的通信方式是Modbus协议,通过Modbus协议传输的数据往往以明文传输,缺乏保密性和安全性,易被篡改。文章提出了一种国产加密方案,设计了一套国产密码硬件设备,已在工业控制系统中试验运行,结果表明设备运行稳定,数据延迟低。

At present, Modbus protocol is the most widely used communication method in the water conservancy automation control system. The data transmitted by Modbus protocol is usually in plaintext, which is lack of confidentiality and security, and easy to be tampered with. In this paper, a set of domestic encryption hardware equipment by using a domestic encryption scheme is designed, and it has been tested in industrial control system. The result shows that the equipment runs stably with low data delay.
