Terminal upgrading protection system and method based on block chain

Abstract

The invention provides a terminal upgrading protection system and method based on a block chain. The system comprises an Internet-of-Things rear end and a plurality of terminals, wherein block chain nodes are respectively deployed on the Internet-of-Things rear end and the terminal; the Internet-of-Things rear end is used for grouping the block chain nodes deployed on the terminal into a pluralityof terminal groups through a decision tree induction algorithm; the rear end of the Internet-of-Things and the plurality of terminal groups construct a block chain network; and upgrading data is packaged, a transaction application is initiated to other block chain nodes in the block chain network, and the upgrading data is in consensus to the block chain network, and the terminal is used for completing upgrading processing by utilizing upgrading data obtained by the deployed block chain node through the consensus of the block chain network.

Description

technical field [0001] The present invention relates to the technical field of blockchain and Internet of Things technology, in particular to a terminal upgrade protection system and method based on blockchain. Background technique [0002] At present, the upsurge of blockchain has swept all walks of life and become one of the hottest and most attention-grabbing information technologies. With the development of block chain technology, more and more individuals and enterprises have begun to use block chain technology to solve some problems. [0003] The Internet of Things is a comprehensive technology and application based on computer science, including network, electronics, automatic identification, wireless, artificial intelligence, barcode, cloud computing, automation, embedded and other technologies. , Refrigerators, cars, equipment, furniture, goods, etc.) are connected to the Internet or local area network, so that they can communicate with each other, and humans can b...

Problems solved by technology

[0004] With the intelligentization of terminals, more and more terminals are connected to the Internet, making the terminals of the Internet of Things more and more large. However, most terminals are small computing devices that can access the Internet through pre-installed software to realize Information interaction with the background system, the pre-installed software of the terminal needs to be continuously updated as the demand changes, but now most of them pass the user password authentication through the back-end and the terminal, and the back-end system sends instructions Or manually upgrade, however, user password authentication also has the possibility of leaking, which is prone to malicious attacks, causing the terminal to be easily implanted with illegal upgrade packages, resulting in the terminal being kidnapped
