Research on Industrial Control System Security Protection Based on Cryptographic Technology

With the application of new technologies such as the Internet of Things, cloud computing, and big data, industrial control systems are increasingly becoming digitalized, networked, and intelligent, which injects vitality into the development of industrial control systems but also brings more network threats. Therefore, strengthening the security protection of industrial control systems has become an important research topic at present. This paper studies the security of industrial control systems under new circumstances, analyzes their future development trends, and in response to new threats, effectively enhances the network security protection capability of industrial control systems by implementing commercial cryptographic technology. It aims to standardize and securely use cryptographic technology, and to ensure the safe and stable operation of industrial control systems.
