Design of Cryptographic Application Scheme for Industrial Control System

Aiming at the current situation and threats of industrial domain security, this paper focuses on the application gaps of cryptography in this domain, deeply analyzes its encryption requirements, and conducts application research. This move aims to solve the cyber security problems faced by the transformation of the industrial domain from a closed to an open environment under the trend of networking, eliminate the constraints on the development of the industry, overcome the application problems of commercial cryptography technology in the domestic industrial domain, and ensure the information security of the industrial domain. This is not only crucial to improving the security of the industrial domain, but also provides strong support for the healthy development of the industrial domain.
