Embodiment Construction

[0043] Below in conjunction with specific embodiment, further illustrate the present invention.

[0044] 1. The blockchain concept of M2M in CPS

[0045] The characteristics of blockchain technology and the technical requirements of M2M in CPS are compatible to a certain extent, which is specifically reflected in:

[0046] (1) Both blockchain technology and M2M embody the idea of ​​distribution and decentralization. In the blockchain technology, there is no centralized database, and each node saves all the information of the blockchain. The CPS physical layer is composed of elements such as energy, environment, personnel and various physical machines and equipment. Interconnection between machines and devices (M2M) is a key technology in CPS, which can be machine-to-machine, machine-to-machine cluster, or machine-to-machine cluster. Regardless of the form of M2M, or point-to-point, point-to-multipoint, or multipoint-to-multipoint communication, all of them reflect distribut...

Abstract

The invention provides an M2M (Machine-to-Machine) security method for a cotton spinning production CPS (Cyber Physical System) based on a block chain technology. A block chain facing the M2M communication security problem is designed according to the characteristic and principle of the block chain technology, an M2M communication system is divided into a public network area, an equipment area anda private area, a machine equipment block chain is designed in the public network area, and a communication block chain is designed in the private area. The block chain technology solves the problemsof equipment change, dynamic maintenance of cotton spinning production materials and security of M2M communication of the cotton spinning production process under the cotton spinning production CPS architecture. The method overcomes the defects of the prior art, and the block chain technology can effectively solve the extensibility of the M2M system in the cotton spinning production CPS and the timeliness and security of M2M communication.

Description

technical field [0001] The invention relates to an M2M security method in a CPS framework oriented to cotton spinning, and belongs to the technical field of communication. Background technique [0002] Entering the era of Industry 4.0, cyber-physical systems, Industrial Internet of Things (IIoT) and Machine-to-Machine (M2M) communications continue to penetrate into the industrial field. A cyber physical system (CPS for short) is a complex system integrating computing, network and physical world. Through the deep integration and collaboration of computing technology, communication technology and control technology, it presents the physical world in the information world in a digital way. Realize the unification of the information world and the physical world. Usually, CPS consists of two main parts, one is the physical world, and the other is the information system. CPS aims to mine and analyze data from the physical world in the information world, intelligently monitor the...
