Electric power Internet of Things access gateway based on a block chain and authentication method for electric power Internet of Things terminal

Abstract

The invention discloses an electric power Internet of Things access gateway based on a block chain, which is applied to a distributed system with characteristics of an electric power Internet of Things. The gateway is composed of a member authentication and authorization module, a block chain service module and a service editing module, and three functions of power Internet of Things terminal identity legality authentication, power Internet of Things terminal authentication certificate and access state storage, and power Internet of Things authentication parameter and protocol configuration are realized respectively. Based on the electric power Internet of Things gateway, the invention also provides an authentication method for electric power Internet of Things terminal access. By utilizing the characteristics of distributed consensus and tamper-proofing of the block chain technology, the authority authentication data is added into the block chain block, and the gateway solves the problem of data trust by inquiring the authentication information and providing the authentication result. The access authentication efficiency is improved, and system calculation and communication resources are saved.

Description

technical field [0001] The present invention relates to the technical field of electric power Internet of Things, in particular to a blockchain-based authentication method for accessing electric power Internet of Things gateways and electric power Internet of Things terminals. Background technique [0002] The number of terminal nodes in the power Internet of Things is large, and the single-point computing and storage capabilities are weak. The traditional centralized access authorization mechanism based on cryptography is difficult to apply, and an efficient distributed solution must be adopted. In the distributed authentication process of the power Internet of Things based on blockchain technology, the terminal authentication group belonging to the same application or coverage area is selected from the power application scenario, and is responsible for access authentication of newly connected nodes. The nodes of the terminal certification group vote on the new entry nodes ...
