Abstract

This disclosure provides a data transmission method and system based on function encryption, blockchain, and machine learning. The edge server performs function encryption on the edge data to obtain edge encrypted data and sends it to the cloud storage server; the structure of the edge server corresponds to the edge encrypted data The data transaction information is sent to the blockchain server; the edge server sends the constructed and trained token generation model to the central server, and the central server uses the token generation model to generate tokens; the token generation model is machine learning Model: the central server obtains and verifies the data transaction information from the blockchain server, and in response to determining that the data transaction information has passed the verification, uses the token to decrypt the edge encrypted data obtained from the cloud storage server, and obtains data in a preset range in the edge data. By combining the related operations of data encryption with the transactions in the blockchain, the reliability of the edge data is guaranteed by using the characteristics that the blockchain cannot be tampered with.

Description

Technical field [0001] The present disclosure relates to the field of data transmission, and more particularly to a data transmission method and system based on function encryption, block chain, and machine learning. Background technique [0002] In the Central Server-Edge Server data management system, the center server needs to obtain edge data in the edge server, the edge server uses the private key to encrypt the edge data to obtain the ciphertext information of the edge data, and send ciphertext information to The central server, the central server uses the public key to decrypt the ciphertext information, thereby obtaining the expressive information of the edge data to consult and use. [0003] However, in an existing data transmission method, the potential malicious edge server may destroy the reliability of the edge data, such as destroying other edge servers, eavesdropping keys, uploading forged data information, etc., the reliability of edge data cannot be guaranteed . ...
