Abstract

The invention relates to a method for designing an event trigger filter of an cyber-physical system under spoofing attack, and the method comprises the following steps: designing an event trigger mechanism according to a formulated T-S fuzzy model, and constructing measurement output of a filter to describe the spoofing attack suffered by the cyber-physical system; according to the spoofing attack suffered by the information physical system, constructing an elastic fuzzy filter corresponding to the spoofing attack; according to the elastic fuzzy filter, constructing a filtering error system for detecting the filtering effect of the elastic fuzzy filter; and under a spoofing attack, verifying the stability of the information physical system in which the elastic fuzzy filter is constructed. The invention aims to improve the bandwidth utilization rate of the information physical system and reduce the false triggering of the data packet.

Description

technical field [0001] The invention relates to the technical field of cyber-physical systems, in particular to an event-triggered filter design method for cyber-physical systems under deception attacks. Background technique [0002] System security is a key issue for the practical application of cyber-physical systems (CPS). In CPS, the deep integration of information space and physical space brings important technical advantages, but at the same time, it also makes it possible for attackers to invade by attacking information space. Physical space, and then willfully destroy cyber-physical systems. Since 2010, the number of security incidents has increased significantly year by year, especially in major industrial control network security incidents showing explosive growth. [0003] The security problem of the cyber-physical system is mainly caused by the destruction of the perception execution layer and the data transmission layer. Malicious attackers destroy or tamper wi...
