Design And Implementation Of A Hardware-in-the-loop Simulation Platform For Cyber-security Of Industrial Control Systems

In recent years, the industrial control systems have a big development, it has being integrated with a large number of IT technologies, such as TCP/IP protocol, Windows operate system etc. However, IT technologies not only bring benefits to industrial control systems but also cyber-threats. Industrial control systems are growing vulnerable and fragile. The security situation is worsening. Since the industrial control systems are continuous operation systems, research works and testing can’t be performed directly in the running systems. So building a simulation platform of industrial control system is an important means to study the security of industrial control systems.Based on the analysis of the security of industrial control systems and the technology used to build a simulation platform for the security of industrial control systems, this thesis proposes a design of a hardware-in-the-loop simulation platform integrated with real hardware devices and a physical plant simulation model. The network control system uses real devices and the physical layer uses a simulation plant. In laboratory, computers, BeagleBone boards and DSP boards based on TMS320F2812 are used to build Modbus TCP/IP network and CAN bus network. Two attack sceneries are designed in this thesis, they are HMI attack and controller/sensor attack. In the last part of the thesis, the Tennessee-Eastman simulation model is used to test the HLP simulation platform with HMI attack experiment and pressure sensor attack experiment.
