Abstract

CPS (Cyber Physical Systems) have got wide application and research, and information security risk evaluation became the key for CPS greatly developing. In view of the physical structure and business characteristics of CPS, this paper constructs an information security risk evaluation system for CPS. In the process of risk evaluation, colligating the analysis results from experts and the analysis results of external data sources’ related big data for information security risk evaluation of CPS, by experts confirming the index system and indexes’ weight values for CPS information security risk evaluation, further through using evaluation model to realize the quantitative calculation to CPS information security risks. This paper proposes using blockchain technology to construct the data’s authenticity and reliability guarantee system for CPS and CPS related external systems, and constructing blockchain’s layered model structure based on CPS. In the part of case analysis, comparing and analysing the evaluation system based on blockchain and big data and the evaluation system based on traditional mode, to confirm the research value of this paper.
