An encrypted data processing method, device, system and storage medium

Abstract

The embodiment of the present application provides an encrypted data processing method, device, system and storage medium, the method includes: sending a data interaction request to the data recording system; receiving the system public key sent by the data recording system; sending a data operation request to the data recording system, The data operation request carries the account ID; the user public key sent by the data recording system is received; based on the user public key, the operation data is homomorphically encrypted to obtain the homomorphically encrypted data; the homomorphic encrypted data is obtained based on the client private key and the system public key respectively. The encrypted data is signed and encrypted to obtain the target encrypted data; the target encrypted data is sent to the data recording system; the operation judgment result sent by the data recording system is received. By implementing an encrypted data processing method in the embodiment of the present application, the data confidentiality of data processing and recording can be guaranteed while ensuring the rationality of data operation.

Description

technical field [0001] The present invention relates to the technical field of data encryption, and in particular, to a method, device, system and storage medium for processing encrypted data. Background technique [0002] With the continuous development of Internet technology, while users perform various services through the Internet, data is exposed to multiple processing platforms or systems during processing or communication, resulting in frequent disclosure of private information, thereby reducing the confidentiality of private information. It not only increases the user's risk, but also does not meet the user's expectation of privacy and confidentiality. [0003] The current data recording system has the problem of insufficient data encryption, and most of the data recording systems are equipped with a corresponding background management system, so that users' private data can be viewed or stolen; at the same time, data recording systems with excessive encryption are i...

Problems solved by technology

[0002] With the continuous development of Internet technology, while users perform various businesses through the Internet, data is exposed to multiple processing platforms or systems during processing or communication, resulting in frequent disclosure of private information, thereby reducing the confidentiality of private information not only increases the user's risk, but also does not meet the user's expectation of privacy and confidentiality

[0003] The current data recording system has the problem of insufficient data encryption, and most data recording systems are equipped with a corresponding background management system, which leads to the user's private data being viewed or stolen; at the same time, the data recording system with too high encryption degree The decryption process in the process of processing data is cumbersome and wastes a lot of processing resources
