Problems solved by technology

[0006] CN110351381A discloses a trusted distributed data sharing method of the Internet of Things based on blockchain, which solves the low efficiency problem under the centralized sharing mode of the Internet of Things. Although a data management module is designed, the on-chain and off-chain data are not specified;
[0007] CN110933093A discloses a block chain data sharing platform and method based on differential privacy protection technology, which solves the existing privacy leakage problem caused by the data sharing process between data providers and data visitors
However, uploading all data to the chain requires a large amount of computing and storage resources, and does not take into account the low efficiency of blockchain transmission of large data

Embodiment

[0071] see Figure 1-7 , the present invention provides a technical solution: a blockchain-based industry IoT data lightweight trusted sharing technology, including the following steps:

[0072] Step 1: Establish a two-layer architecture system model including the physical network layer and the blockchain network layer based on federated learning and blockchain;

[0073] Step 2: According to the IoT data of the first step activity and certain types of business data received by blockchain nodes, formalize the data according to the rules to construct the data model, unify the data model, and realize data modeling, on-chain management and data shared;

[0074] Step 3: Improve the trusted sharing performance of IoT data by optimizing the three aspects of Raft algorithm leader election, log replication and security. Raft nodes communicate through Remote Procedure Call (RPC) , each Raft node contains the following attributes currentTerm, votedFor, log, commitIndex, lastApplied, ne...

Abstract

The invention discloses an industry Internet of Things data lightweight trusted sharing mechanism based on a block chain. The mechanism utilizes the block chain and a federated learning algorithm to realize data sharing and privacy protection. The Raft algorithm is optimized in the aspects of owner selection, log replication and safety, the consensus efficiency is improved, and the requirements ofa smart city for time delay and safety are met. A transaction mechanism is designed based on a smart contract, thus standardizing a transaction process, and improving the enthusiasm of an Internet ofThings data holder to participate in data sharing through excitation.

Description

technical field [0001] The invention relates to the field of communication technology, and the specific field is a lightweight and trusted sharing technology of industrial IoT data based on blockchain. Background technique [0002] Smart cities collect, process, and apply IoT data in all aspects of urban operation through information and communication technology, thereby providing intelligent overall planning and coordination for various needs including urban management, ecological environment, transportation, and energy. In order to enhance the city's perception capabilities, the scale of IoT devices is gradually expanding, and traditional device access methods can no longer meet the requirements for data security and stability. At the same time, due to the phenomenon of information islands, it is difficult for various institutions to share data, making it difficult to achieve cross-departmental collaboration and precise services. [0003] In order to solve the above probl...
