Iteration Composition Analysis of Non-Interference in Cyber-Physical System
Special Issues Editor (Nottingham Tent University, United Kingdom (Great Britain))
At present, a rather big challenge to model cyber-physical systems is to stand for the interactions between physical level and cyber level. Researchers are faced with the trouble in the analysis of information security property of noninterference in cyber-physical systems because of the physical components and behavior appended to cyber components and systems. A new method is put forward with Petri net for working out this problem effectively by composing the complicated and large systems with simple and small systems. Meanwhile, it accomplishes the noninterference information flow security property. In this paper, this method is used to analyze the information security property of noninterference and its iteration composition in cyber-physical systems. This research provides a new formal method to explore information security property of noninterference and a sufficiency and necessary condition of iteration composition of noninterference of information security model in cyber-physical systems.
