Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a blockchain data encryption system, which solves the problem that traditional data is encrypted and protected only when uploaded, but in this method, the data sender or The identity of the recipient is impersonated or forged by others to destroy the encryption of the data, which will lead to the problem of data being tampered with, deleted or lost during transmission

Abstract

The invention discloses a data encryption system for a block chain, and the system is characterized in that the output end of a first plaintext unit is electrically connected with the input end of anAES encryption unit, the output end of a first AES key unit is electrically connected with the input end of the AES encryption unit, the output end of the AES encryption unit is electrically connectedwith the input end of a first ciphertext unit, the output end of the RSA encryption unit is electrically connected with the input end of the first ciphertext unit, the output end of the first plaintext unit is electrically connected with the input end of the first DS5 abstract unit, and the output end of the first DS5 abstract unit is electrically connected with the input end of the RSA encryption abstract unit. The invention relates to the technical field of data encryption. According to the data encryption system for the block chain, the problem that when traditional data is uploaded, single encryption protection is conducted on the data, but in the method, when the identity of a data sending party or a data receiving party is pretended or forged by others to destroy encryption of the data, the data can be tampered or deleted or lost in the transmission process is solved.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to a data encryption system for blockchain. Background technique [0002] A blockchain is a database with data "hash verification". Blocks are data blocks. Data blocks are combined into a chain structure in chronological order, and cryptographic algorithms are used to collectively maintain the reliability of the database in the form of distributed accounting. All data blocks are connected in chronological order to form a blockchain. Blockchain technology refers to multiple nodes based on encrypted chain block structure, distributed node consensus protocol, P2P network (peer-to-peer network) communication technology and intelligent A decentralized infrastructure composed of technologies such as contracts. Blockchain technology is an integration of multiple mature technologies. Blockchain technology originates from the underlying framework of the Bitcoin system. It is a dis...
