Research survey on defense strategy of attack threat in cyber physical systems
Cyber-physical systems are intelligent system that connect physical objects and computational units through cyberspace,forming an integrated framework of"perception-transmission-decision-control".As cyber-physical systems are applied to many critical infrastructures,their security issues have attracted researchers'interest.Firstly,typical modeling methods for cyber-physical systems are presented to meet the needs of performance analysis.Then,three representative network attack models(denial of service attack,spoofing attack and replay attack)are constructed from a mathematical representation perspective,laying the foundation for the study of defense methods.Next,both specific and general defense methods are summarized for cyber-physical systems,and the latest research progress is reviewed.Finally,existing problems are identified from four different perspectives,and future research directions are discussed.
