Embodiment Construction

[0029] The present invention will be further described below in conjunction with drawings and embodiments.

[0030] Such as figure 1 As shown, the industrial wireless control system semi-physical security experiment platform provided by the present invention includes a simulation module for simulating a virtual controlled object, a controller host computer, a physical communication network, and an attacking device universal software radio USRP. The simulation module is used to simulate the industrial control system of mathematical abstraction. This embodiment takes the four-capacity water tank system simulated in the Matlab simulation software as an example. First, fill in the discretized state parameters of the four-capacity water tank model in the MatlabM file, and write to realize The state signal changes the function in real time after obtaining the control signal, so as to obtain the real-time state under the corresponding control signal, and then through visual programmi...

Abstract

The invention discloses an industrial radio control system semi-physical security experiment platform. The platform comprises a simulation module, a controller host computer, a monitoring site, a programmable logic controller (PLC), an industrial radio communication device and a universal software radio peripheral (USRP) for simulating attacks. The simulation module is used for erecting a virtual controlled object and simulating different industrial scenes. The controller host computer is used for simulating different control algorithms. The monitoring site monitors in real time state signals, control signals and the like in a system operation process and stores correlation data in a database. The USRP is used for simulating a typical industrial radio attack mode. According to the experimental platform, through simulating a typical industrial object and a control algorithm, an attack on an industrial radio channel is simulated by use of the USRP, and the security of an industrial radio protocol and the control system performance under a typical attack are analyzed. The industrial radio control system semi-physical security experiment platform is low in system cost and can be applied to simulation of a typical industrial control object and a corresponding control algorithm and evaluation of the influence of a typical industrial radio attack on an industrial control system.

Description

technical field [0001] The invention relates to the security field of industrial control systems, in particular to a semi-physical security experiment platform for industrial wireless control systems. Background technique [0002] In recent years, with the rapid development of industrial wireless network technology, industrial wireless network has been widely used. Compared with traditional wired industrial control systems, wireless communication technology is a non-contact transmission method. Due to low installation and maintenance costs, Easy to replace, easy to deploy and other features, it has been widely used in industrial control system process monitoring, transmission control, threshold alarm, etc. However, although wireless industrial communication technology has many advantages, as an open communication method, its transmission medium is more vulnerable to various external attacks and security risks than wired networks, including denial of service attacks, signal e...
