Safety Framework Based on Blockchain for Intelligent Manufacturing Cyber Physical System

With the development of intelligent manufacturing CPS, the traditional security architecture has been unable to meet its common requirements for functional security and information security. In this paper, based on the decentralization, security and trustworthiness of blockchain, a block-based intelligent manufacturing CPS safety protection framework is proposed, and the concrete structure of the framework at the basic level and integration level is introduced. Finally, the safety of the framework is demonstrated from five dimensions for the information security features and functional security features. This research provides new research ideas for building a safer and more robust intelligent manufacturing CPS.
