Embodiment 1

[0061]SeeFigure 1-3As shown, the present invention is a block chain decryption service security trusted system based on TEE technology, and the work steps of the TEE technology-based block chain decryption service security trusted system include:

[0062]S1: Get sub-storage data of each sub-node, transmit sub-storage data of each sub-node to the central node, the sub-storage data contains the use of stored data and unused storage data of each sub-node;

[0063]S2: The sub-storage data of all sub-nodes is received and classified by the center node, and the first storage data and the second storage data are obtained, the first storage data contains the use of stored data in the sub-node. The second storage data contains unused storage data in all of the subtots;

[0064]In the embodiment of the present invention, by statistical and dividing the use of stored data in each sub-node, the processing is performed by the center node, it is easy to make a reasonable memory distribution for the storag...

Abstract

The invention discloses a safe and trusted system for blockchain encryption and decryption services based on TEE technology, which acquires sub-storage data of each sub-node and sends the sub-storage data of each sub-node to a central node; using the central node receiving and categorizing the sub-storage data of all sub-nodes to obtain the first storage data and the second storage data; sorting the unused storage data in the second storage data in descending order, calculating and obtaining a balanced storage value; using the balance The storage value divides the second storage data to obtain divided storage sets; acquires the data to be stored and generates a storage instruction; stores and allocates the data to be stored according to the divided storage sets according to the storage instruction; according to the to-be-read The read instruction in the data reads the data, which solves the problem of unreasonable memory allocation of each sub-node in the blockchain encryption and decryption service, which leads to poor credibility and the inability to balance the efficiency and security of data encryption and decryption.

Description

Technical field[0001]The present invention relates to the field of block chains, and more particularly to a block chain and decryption service security trusted system based on TEE technology.Background technique[0002]TEE is expressed as a trusted execution environment that can guarantee that it is not calculated by conventional operating system interference, it is called "credible". In summary, TEE is a separate execution environment that runs parallel with Rich OS, providing security services for the Rich OS environment. TEE is independent of Rich OS and its application, to access hardware and software security resources; TEE technical philosophy "," When performing sensitive operation or high active behavior (such as fingerprint comparison, payment action with private key signature) Wait, the system security level in Normal World is not sufficient to cope with it, and it is necessary to put it in Secure World, providing a high-security execution environment for a series of sensiti...
