Data distributed privacy protection method based on smart contract and SGX

Abstract

The invention provides a data distributed privacy protection method based on an intelligent contract and an SGX, and the method comprises the steps that S1, a user transmits a data access request to an SGX trusted platform through equipment, and the SGX trusted platform is deployed at an edge computing node; s2, after receiving the data access request, the SGX trusted platform performs data interaction with an intelligent contract deployed in a block chain to check whether a user is allowed to access data or not; and S3, the SGX trusted platform acquires an access control result fed back by the smart contract, and processes a data access request of the user according to the access control result. The method can effectively improve the credibility of the system, and has the advantages of high timeliness, small delay, reliable data storage, traceability, high safety and the like.

Description

Technical field

[0001] The present invention relates to the field of data protection, and more particularly to a data distributed privacy protection method based on intelligent contract and SGX.Background technique

[0002] In the era of information explosion, the value of data is undoubtedly contributed to the development of large data technology. The value of data is critical to a wide range of science and industrial processes. Digitalization of workflow is a big trend in all industries. As this trend changes, the amount of data obtained by electronically has increased dramatically, and these electronic data have complexity, diversity, and large amounts. Data security is an important part of big data. Data is facing many severe challenges during collection, storage, and use. Among them, people's emphasis on data security and privacy issues are increasing, and data is stored in the local computer or On the cloud server, this method is easy to attack, and the security of the data cannot b...
