水利自动化控制系统中现场总线安全技术研究

Research on safety technology of fifield-bus in automation control system of water conservancy

摘要:

在水利自动化控制系统中，广泛使用 Modbus 协议作为现场总线网络的串行通信协议，由于其缺乏访问控制、密钥管理、终端安全等措施，给系统带来不可避免的安全风险。研究国产混合加密技术的硬件安全模块，对使用 Modbus 协议通信的现场总线网络进行改进和保护。在无需进行现地大规模网络基础设施改造的前提下，提出一种安全稳定、自主可控、经济便利的水利自动化控制系统现场总线安全技术方案。

Abstract:

In the water conservancy automation control system, Modbus protocol is widely used as the serial communication protocol of fifield-bus network. Due to its lack of access control, key management, terminal security and other measures, it brings inevitable security risks to the system. This paper studies a hardware security module of domestic hybrid encryption technology to improve and protect the field-bus network using Modbus protocol communication. On the premise that there is no need to transform the local large-scale network infrastructure, it puts forward a safe and stable, self-controllable, economical and convenient fifield-bus security technical scheme of water conservancy automation control system
