Embodiment 1

[0030] This embodiment provides a blockchain data security storage framework for the edge layer, and the framework includes: a perception layer, an edge layer and a cloud layer.

[0031] The perception layer is used to collect power grid status data; the perception layer includes multiple data collectors, and each data collector acts as a client in the blockchain system; the clients can communicate with each other through wired or wireless communication channels ; The client includes RAM, computing hardware, data acquisition equipment, signal transmitter, signal receiver and data processing device; the client has a unique address identification, and the client can support the generation of public key and private key .

[0032] The edge layer is used to receive and store the grid status data; the edge layer includes a plurality of edge nodes as the carrier of the blockchain, each of which is a blockchain node in the blockchain network, and the blockchain Nodes are divided into...

Embodiment 2

[0038] This embodiment provides a multi-block chain architecture method for data security storage at the edge layer, which improves the data security during and after storage of the data at the edge layer, and improves the resistance to network attacks; at the same time This method solves the problem of too many nodes in the case of a single blockchain, and the time spent sharing data and consensus is too long.

[0039]The present invention is mainly to solve the data security after the data uploaded by the bottom sensor in the smart grid to the edge layer and stored, and the following technical solutions are adopted to realize:

[0040] The data safe storage method includes the following steps:

[0041] The client submits a storage request message to the execution node group. After the execution node group receives the storage request, it verifies the identity information of the requester, and after confirming its authority, the main execution node adds the received message t...

Abstract

The invention discloses a blockchain data security storage framework and method in the technical field of data security storage. The method aims to solve the security problem of smart grid edge data storage, nodes in a blockchain system are overlapped and grouped, and each node group is divided into an execution node group and a common node group; the execution node is responsible for receiving, processing, packaging and storing data, and the common node is responsible for receiving, verifying and storing data and serves as a backup execution node. A Raft consensus algorithm is used in the execution node group to achieve sharing of message queues among all nodes, and after the execution nodes break down, common nodes are selected as new execution nodes. According to the method, the security of intelligent power grid edge data storage is improved by utilizing the tampering resistance of the blockchain, the demand of the blockchain for storage resources is reduced by utilizing a multi-chain structure, the node consensus time is shortened by utilizing a dynamic Raft algorithm, and the data storage efficiency is improved.

Description

technical field [0001] The invention relates to a multi-chain block chain data security storage method based on Raft algorithm, belonging to the technical field of data security storage. Background technique [0002] Edge computing is a distributed architecture used in the Internet of Things that integrates potentially billions of sensors, cameras, industrial machines, displays, smartphones, and other smart Process data in an automated environment to automate the end-to-end manufacturing lifecycle. Edge computing can be regarded as a member of a decentralized network, providing device computing, storage and network services for terminals. Edge computing built-in embedded chip data storage itself does not have its own encryption mechanism, which makes the stored data easy to leak and tamper. [0003] In the smart grid system, the security and reliability of data is the basis for ensuring the stable and normal operation of the system. In today's era of advanced Internet tech...
