Intelligent Attack Method Research on the Pressure Control System of Pressurizer

In order to provide help to the research and development of security defense system for pressurizer in nuclear power plant, this paper studies the potential attack mode in pressurizer distributed control system (DCS) and proposes a covert attack approach based on least square support vector machine (LSSVM) algorithm. This method uses the LSSVM algorithm to identify the system to obtain a high-precision estimation model of the attacked area of pressurizer, and use this estimation model to realize the covert attack. The simulation results show that the attack method not only causes some damage to the pressure control system of pressurizer, but also has high concealment performance.
