Internet of Things equipment mutual authentication method and device based on block chain technology

Abstract

The invention discloses an Internet of Things equipment mutual authentication method and device based on a block chain technology, which can improve the computing power of the Internet of Things, especially for the Internet of Things with an edge computing scene, the computing can be directly placed at an edge end after the equipment passes authentication, and the equipment can also communicate with each other to utilize data of the opposite side, so that the computing efficiency is improved. The authentication mechanism between the devices also ensures the identity security of the devices, and different internet-of-things data islands can be broken through; according to the invention, the application scale of the Internet of Things can be expanded, the expansion capability of the Internet of Things is improved, different Internet of Things communication can be realized based on the cross-chain technology, and the method is the basis for constructing the large-scale Internet of Things; according to the method, the security of the Internet of Things can be improved, the block chain network has the characteristics of decentralization, tampering prevention and the like, and the security problem of the Internet of Things can be solved in addition to registration and authentication processes provided by the invention.

Description

technical field [0001] The present invention relates to the fields of blockchain and Internet of Things, in particular to a method and device for mutual authentication of Internet of Things devices based on blockchain technology. Background technique [0002] In practical applications, IoT devices are massively dispersed, and trusted communication between IoT devices is an urgent problem to be solved. As a large-scale distributed decentralized system, the blockchain provides permanent data storage and tamper-proof features through the hash chain and consensus algorithm, which can effectively assist the Internet of Things to solve various security problems. [0003] The combination of blockchain technology and Internet of Things technology, the characteristics of blockchain decentralization, non-tampering, high security, and traceability can truly and effectively solve the security, trust, privacy, performance issues. [0004] (1) The blockchain can improve the computing po...
