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

Abstract

The invention provides a credible execution environment implementation method, which comprises the following steps of: closing all remote access services of a pre-selected basic operation system of adata providing end, and installing a remote access application program of a preset type; manufacturing a mirror image of the basic operation system; adding a digital signature to the mirror image, andwriting the digital signature into the block chain; when a credible execution environment starting instruction is received, a digital signature corresponding to the target mirror image is obtained from the block chain to serve as a verification digital signature; if it is judged that the verification digital signature is valid, calling a target mirror image; and running the installed remote access application program, generating a remote access address of the data providing end, and sending the remote access address to the data using end. The invention further provides a credible execution environment implementation device, terminal equipment and a readable storage medium. The technical problems that an existing data providing mode is prone to data leakage and algorithm leakage are solved.

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...
