Block chain trusted privacy computing capability improving system based on TEE technology

Abstract

The invention discloses a block chain trusted privacy computing capability improving system based on the TEE technology; the system is characterized in that a data filtering unit is arranged to filter and remove impurities from acquired data, and identify and delete illegal data, repeated data and empty data doped in the data. Meanwhile, trust value and credit granting level association is carried out on a data source of the data, so that the data value and purity of the collected data are improved; by arranging a data processing unit, an independent operation space is opened up to integrate and normalize the extracted data, and all the data participating in calculation is calculated in the independent operation space, so that the safety of the data and the leakproofness of data privacy protection are improved; by arranging the data management unit, the audit data set, the non-activated data set and the trust value are managed, and the data in the data storage unit are subjected to timed space release, so that the whole system space can complete storage and calculation more efficiently.

Description

technical field [0001] The present invention relates to a capability improvement system, in particular to a blockchain trusted privacy computing capability improvement system based on TEE technology. Background technique [0002] TEE, also known as Trusted Execution Environment, is a secure area isolated from the host system. TEE technology adds hardware expansion capability to the existing CPU, and obtains an execution environment isolated from the host environment based on the combination of software and hardware, and ensures the confidentiality and integrity of the code and data loaded in the isolated environment. The host environment It will run concurrently with the TEE as a REE environment (general computing environment), and can use the secure communication mechanism to obtain the services of the TEE. The hardware isolation mechanism ensures that the components in the TEE are not affected by the software running in the REE, which is a series of functions provided to ...
