Problems solved by technology

In addition, since the ciphertext is encrypted, even if the server is compromised, the user's private data cannot be leaked, which can further ensure the security of the data stored in the server, and is used to solve the problem that the server cannot guarantee that the user's private data will not be leaked in the prior art. Leaked technical issues

Abstract

The invention provides a data processing method based on homomorphic encryption and a device thereof, and the method comprises the steps: obtaining a processing request of data from a client; whereinthe processing request is used for requesting to execute a data processing operation on a stored data item; executing the data processing operation on a ciphertext of the data item corresponding to the operation according to the operation required for executing the data processing operation to obtain an encryption result; wherein the ciphertext is obtained by encrypting the data item by the clientthrough adoption of a homomorphic encryption algorithm corresponding to the data processing operation; and generating and sending a processing response carrying the encryption result. According to the method, the processing functions of query, analysis and the like of the encrypted data can be provided on the server side, and since the ciphertext is obtained after encryption processing of the client, the server cannot view the private data of the user, and the private data of the user can be prevented from being leaked.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a data processing method and device based on homomorphic encryption. Background technique [0002] At present, enterprises can collect a large amount of data and use server resources to analyze the above data. However, if some sensitive data is not encrypted, when the server has a security breach, it may lead to the leakage of the enterprise's sensitive data, and , the server can obtain the user's private data, and when the user's private data is encrypted and stored on the server, the server cannot provide analysis and query functions for the encrypted private data. [0003] In the prior art, in order to avoid the above-mentioned private data or sensitive data from being leaked, the server can actively encrypt the uploaded data, and the encryption key is managed by the server. During data processing, the big data analysis tool can analyze the data Decry...
