Trusted execution environment implementation method and device, terminal equipment, and readable storage medium

Abstract

The invention provides a trusted execution environment implementation method, comprising: closing all remote access services of the pre-selected basic operating system of the data provider, and installing a preset type of remote access application program; making a mirror image of the basic operating system; adding a digital image to the mirror image signature, and write the digital signature into the block chain; when receiving the trusted execution environment startup instruction, obtain the digital signature corresponding to the target image from the block chain as the verification digital signature; if it is judged that the verification digital signature is valid, Then call the target image; run the installed remote access application program, generate the remote access address of the data provider, and send the remote access address to the data user. The invention also provides a trusted execution environment realization device, a terminal device, and a readable storage medium. The invention solves the technical problem that data leakage and algorithm leakage are easy to occur in the existing data providing method.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a trusted execution environment implementation method and device, terminal equipment, and a readable storage medium. Background technique [0002] At present, the data provision method between different organizations is to copy the data into the other party’s environment, and the data owner cannot effectively monitor whether the data is illegally copied or lost; or the data user uses the data in the data owner’s environment, and there is How it is used is peeped by the data owner. In other words, when sharing data between different organizations, it is necessary to sacrifice the source data security or algorithm security of one party; data or algorithms are used and generated in an insecure environment, which is prone to data leakage and algorithm leakage. [0003] The above content is only used to assist in understanding the technical solution of the present inv...
