Electric power internet of things data trusted exchange method and system based on alliance chain identification service

Abstract

The invention provides an alliance chain identification service-based power Internet of Things data trusted exchange method and system. The method comprises the steps of allocating an identity identifier to a power Internet of Things terminal according to equipment information and deployment information of the power Internet of Things terminal; acquiring a corresponding data cache address from a resource identifier library of a block chain based on the identity identifier; and encrypting data of the power Internet of Things terminal by adopting a data signature and an asymmetric encryption technology, and storing an encrypted ciphertext to a block chain according to the data cache address, or obtaining the ciphertext from the block chain based on the data cache address, decrypting the ciphertext, and sending the decrypted ciphertext to the power Internet of Things terminal. And credible interaction between the power Internet of Things terminal and the block chain is completed. According to the method, the corresponding data cache address is obtained through the identity label, data credible indexing and credible verification of data tampering are achieved, and safe and transparent transmission and sharing of data are guaranteed through the data signature and the asymmetric encryption technology.

Description

technical field [0001] The invention relates to the technical field of the power Internet of things, in particular to a method and system for trusted data exchange of the power Internet of things based on a consortium chain identification service. Background technique [0002] With the development of information and communication technology, the increasing demand for power grid intelligent services and ubiquitous business access to the energy Internet has put forward higher requirements for the ability of information and communication technology to support power grid services. The power communication network supports business security and reliability. , The need for flexible access is very urgent. However, the characteristics of the complex network architecture, cloudification of the main station, IoT of terminal equipment, flexible business expansion and other characteristics of the Internet of Power Internet of Things have led to great changes in the security risks faced b...
