Trusted data transmission method and system, electronic equipment and storage medium

Abstract

The invention provides a trusted data transmission method and a system, electronic equipment and a storage medium. The trusted data transmission method comprises the following steps: acquiring data; calculating an abstract value of the collected data, and encrypting the abstract value according to a private key of the edge computing node to generate an edge computing node signature; generating a message serial number for the acquired data; caching the abstract value and the message serial number of the acquired data; generating a data message according to the public key of the target blockchain node; sending the data message to the target blockchain node for decryption and verification; receiving a feedback message sent by the target blockchain node; and decrypting the feedback message according to the private key of the edge computing node, comparing the decrypted data with the cached abstract value and message serial number of the acquired data, and if the decrypted data is consistent with the cached abstract value and message serial number of the acquired data, finishing the transmission of the acquired data. According to the method and the device provided by the invention, thesecurity of message transmission between the Internet-of-thingsInternet-of-things and the blockchain can be realized.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a trusted data transmission method, system, electronic equipment, and storage medium. Background technique [0002] In 2008, a scholar named "Satoshi Nakamoto" published the paper "Bitcoin: A Peer-to-Peer Electronic Cash System", laying the foundation for blockchain technology. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures a non-tamperable and non-forgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate update data, uses cryptography to ensure data transmission and party security, and uses automated script codes to A new distributed infrastructure and computing paradigm that consists of smart contracts to program and manipula...

AI Technical Summary

Problems solved by technology

[0007] 1) The data generated by the current edge computing nodes has the risk of easy tampering and data leakage;

[0008] 2) At present, the hardware (such as single-chip microcomputer) of most edge computing nodes cannot directly install and run the blockchain client software to connect to the blockchain;

[0009] 3) At present, most of the Internet of Things use the cloud platform as an intermediary to send the collected IoT data to the blockchain, thus introducing the risk of tampering and leakage of the data collected by the cloud platform service provider to the Internet of Things
