Abstract

The invention relates to a ship CPS system spoofing attack detection method and system, and solves the problem that the ship CPS system spoofing attack cannot be detected in the prior art. The methodcomprises the following steps: acquiring a system state vector and a system output signal of a ship CPS system; estimating a system state vector at the next moment according to the system state vectorand the system output signal, and calculating an estimated value of the system output signal at the next moment; calculating to obtain a residual signal according to the system output signal estimated value and the system output signal; and obtaining a residual error evaluation function according to the residual error signal, calculating a residual error threshold value, and comparing the value of the residual error evaluation function with the residual error threshold value, thereby realizing ship CPS system spoofing attack detection.

Description

technical field [0001] The invention relates to the technical field of ship CPS system attack detection, in particular to a ship CPS system spoofing attack detection method and system. Background technique [0002] In recent years, with the rapid development of electronics, information and other technologies, the ship CPS system (cyber-physical systems) came into being based on the overall needs of shipbuilding. The ship CPS system is composed of decision-making, It consists of network layer and physical layer. Its basic components include sensors, control execution units, computing processing units, and communication networks. [0003] Among them, the sensor collects the data of the physical system; the collected data is transmitted to the information system, and the calculation and processing unit conducts data analysis to obtain control decisions; the control execution unit applies control signals to the physical system according to the decisions. The above processes ar...
