Remote data control method, device and equipment based on confidential computing technology

Abstract

The invention provides a remote data control method, device and equipment based on a confidential computing technology, which are used for solving the technical problem that confidential data are uncontrollable after cross-domain sharing. According to the invention, an authenticated security sharing module is deployed in a confidential computing environment of a data user, and the security sharing module controls use behaviors of confidential data based on a data security control strategy issued by a data owner and reports a data operation state and an operation result. According to the data sharing method and device, the data owner still has the control right for the data shared to the data user and can obtain the proof that the data is successfully operated according to the intention of the data owner, so that the technical problem that the data owner loses the control of the data once sharing the data to the data user in a cross-domain manner is effectively solved; and the confidentiality and integrity of cross-domain data of the user are fully ensured.
