Power Internet of Things equipment identity authentication method and system based on block chain

Abstract

The invention belongs to the field of power automation, and discloses a power Internet of Things equipment identity authentication method and system based on a block chain, and the method comprises the following steps: power Internet of Things equipment generates authentication request information, and sends the authentication request information to a block chain network; wherein the authentication request information comprises equipment parameter information and a digital certificate of the power Internet of Things equipment; the block chain network queries whether an internal block chain contains a target block or not; wherein the target block is a block containing equipment parameter information and a digital certificate of the power Internet of Things equipment; and when the block chain contains the target block, the block chain network sends a reliability certification message to the power Internet of Things equipment to complete identity authentication of the power Internet of Things equipment. The problems of low compatibility, weak anti-attack capability, heavy centralized network burden and the like in a public key infrastructure-based identity authentication process commonly used in the power internet of things at present are effectively solved, and high-security distributed power internet of things equipment identity authentication is realized.

Description

technical field [0001] The invention belongs to the field of electric power automation, and relates to a block chain-based identity authentication method and system for power Internet of Things devices. Background technique [0002] In recent years, with the increasing social demand for electric energy, the electric power industry has achieved rapid development. Among them, the power Internet of Things is supported by modern smart grid technology, combined with modern advanced information, communication and perception technologies, to realize the deep integration of smart grid information flow, power flow and business flow, thus providing important technical support for the stable operation of the power industry . At the same time, the wide application of power Internet of Things has also promoted the real-time monitoring and perception of smart grid operation, providing an important guarantee for the safety and stability of power grid operation. However, the wide applicat...

Problems solved by technology

This inherent centralization based on a trusted certificate authority: on the one hand, as a third-party certification center, its credibility cannot be guaranteed due to the difficulty in making its operation records open and transparent

On the other hand, if there is a single point of failure in the certification center or the leakage of the secret key, the identity information of the device will be lost or even tampered with, and even the entire trust system will collapse.
