Abstract

As the core of intelligent manufacturing, cyber-physical systems (CPS) have serious security issues, especially for the communication security of their terminal machine-to-machine (M2M) communications. In this paper, blockchain technology is introduced to address such a security problem of communications between different types of machines in the CPS. According to the principles of blockchain technology, we designed a blockchain for secure M2M communications. As a communication system, M2M consists of public network areas, device areas, and private areas, and we designed a sophisticated blockchain structure between the public area and private area. For validating our design, we took cotton spinning production as a case study to demonstrate our solution to M2M communication problems under the CPS framework. We have demonstrated that the blockchain technology can effectively solve the safety of expansion of machines in the production process and the communication data between the machines cannot be tampered with.

Highlights

  • A cyber-physical system (CPS) is a complex system of computation, networks, and the physical world [1]

  • We introduced blockchain technology to the security of M2M communication of a CPS

  • According to the characteristics and principles of a blockchain, we have presented a design of a blockchain for M2M

Summary

Introduction

A cyber-physical system (CPS) is a complex system of computation, networks, and the physical world [1]. Communication, and control technologies, a CPS digitizes the physical world and realizes the unity of the information world and the physical world. This paper attempts to solve the security of M2M in a CPS using blockchain technology. Symmetry 2017, 9, 193 technology to solve the security problems of M2M communication is introduced; (2) the design of a blockchain for M2M communication security is presented; and (3) the application of blockchain technology to a case study of cotton spinning is given.
