Internet of Things information security transmission system and transmission method based on a block chain

Abstract

The invention discloses an Internet of Things information security transmission system and transmission method based on a block chain, the transmission system comprises a control end, a block chain network and a plurality of controlled ends, the control end is in communication connection with all the controlled ends, and the control end and all the controlled ends respectively comprise a block chain module and an Internet of Things module; And the control end manages the controlled end through an intelligent contract, and the intelligent contract comprises a contract owner, an equipment whitelist and an operation interface. According to the method, the characteristics of decentralization, encryption algorithm, privacy protection and the like of the block chain network are utilized, the block chain technology is introduced into an Internet of Things system, equipment related information and part of security information are stored in the block chain network, a centralized cloud platformis removed, encryption transmission is carried out on the information, and therefore the information security related problem of the Internet of Things is solved.

Description

technical field [0001] The present invention relates to the field of Internet of Things information security, in particular to a block chain-based Internet of Things information security transmission system and transmission method. Background technique [0002] At present, the number of IoT devices is increasing by leaps and bounds. According to the forecast of relevant agencies, it will reach about 25 billion in 2020. IoT devices have entered tens of millions of ordinary households, such as AI speakers, smart cameras, etc., but currently in scenarios such as smart homes, the relevant information of users and devices is stored on a centralized platform, based on a centralized network The model needs to invest a lot of cost, and at the same time, there will be great security risks. There have been many IoT security incidents, such as botnet and DDos attacks, remote video recording, etc. [0003] In view of the wide application of the Internet of Things and the importance of...
