摘要： A method 300 of generating invariants for distributed attack detection on a cyber-physical system 100 having a number of system components is provided. In a described embodiment, the method 300 includes deriving design invariants at 310 based on system design of the cyber physical system 100 including physical specifications of the system components, obtaining operational data of the cyber physical system at 320 including operational attributes of the system components, generating operational invariants from the obtained operational data at 330, and correlating the operational variants with the design invariants at 340 to generate an integrated set of invariants for detecting distributed cyber attacks of the cyber physical system 100.
