Improving Industrial Control System Security with Smart Contract Technology

Abstract

With the rapid development of the industrial internet of things and the standardization of industrial control protocols, the threats of cyberattacks targeting industrial control systems are gradually increasing. Given that industrial control systems are widely used in various critical infrastructures, cyberattacks on these systems can endanger public safety and impact the stable operation of society. As the cybersecurity of industrial control systems gaining increasing attention, there is a need to design a more secure mechanism for storing operational data of industrial control devices to improve their safety. By applying blockchain technology to the storage of data within industrial control systems, the chances of data tampering can be reduced. Additionally, while storing data, smart contracts can be employed to determine whether the values of this data fall within a normal range, further improving the operational safety of the system.
