工业互联网层级架构与安全: 复杂网络新视角

Industrial Internet is the product of deep integration between new-generation information technology and the manufacturing industry. Through constructing a new type of industrial manufacturing platform for human-cyber-physical networks, the Industrial Internet is rapidly driving the transformation and development of manufacturing mode towards digital, networked, and intelligent formulation. From a forward-looking perspective, this paper aims to systematically elaborate the hierarchical architecture and system security of manufacturing Industrial Internet based on the theory and methods of complex network cooperative control systems. In detail, the differences between traditional industrial manufacturing systems and Industrial Internet will be discussed from the aspects of key functional components and their core technologies at the device, production line, enterprise, and cross-enterprise levels, respectively. Furthermore, the paper also highlights key technologies and challenges of Industrial Internet security, including intelligent protection interfaces for new terminal devices, resilient self-healing industrial control networks, IT/OT cross-domain trust transmission and anomaly detection, industrial data circulation protection and traceability.
