Abstract

Disclosed is a data sharing method and an electronic device. The data sharing method includes: acquiring encrypted data to be analyzed, selected by a data user, in a data sharing platform; and decrypting, by using a trusted execution program, the encrypted data to be analyzed to obtain decrypted data, and performing, by using the trusted execution program, data analysis on the decrypted data, to obtain a data analysis result of the encrypted data to be analyzed, where the trusted execution program is provided with identity authentication information of the data user set in a built-in manner, and an execution process of the trusted execution program is invisible to the data user, which can ensure the security of shared data in a process of data sharing and improve the efficiency of data analysis.

Claims15

Dependent claims

A data sharing method, comprising:

acquiring encrypted data to be analyzed and a trusted execution program, selected by a data user, in a data sharing platform;
and
decrypting, by using the trusted execution program without exposing an execution process of the trusted execution program to the data user, the encrypted data to be analyzed to obtain decrypted data, and
performing, by using the trusted execution program without exposing an execution process of the trusted execution program to the data user, data analysis on the decrypted data, to obtain a data analysis result of the encrypted data to be analyzed,
wherein identity authentication information of the data user is embedded in the trusted execution program.
