Information security interaction method of IoT intelligent terminal based on blockchain and ipfs technology

Abstract

The invention discloses an information security interaction method of Internet of Things intelligent terminals based on blockchain and IPFS technology, which mainly solves the problems in the prior art of security of Internet of Things terminal information transmission, cumbersome cross-device interaction, and high pressure on device information storage. Through the introduction of blockchain technology in the interaction and collaboration of Internet of Things cross-terminal devices, intelligent terminals of different structures can become equal and independent blockchain nodes, actively participate in the interaction and maintenance of information, and solve the problem of information interaction between heterogeneous devices. Highly dependent on centralized servers. After initiating a request in a decentralized application and triggering a smart contract, the relevant nodes of the blockchain network that meet the conditions respond to the request and send the required information. The problem of frequent centralized processing interactions resulting in low efficiency, high consumption, and high data transmission risks has been improved. At the same time, using the traceability feature of blockchain technology, the interactive operation information between nodes is saved on the chain, and when malicious nodes tamper with shared data, they can be traced and held accountable.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things block chain, and in particular relates to an information security interaction method of an Internet of Things intelligent terminal based on block chain and IPFS technology. Background technique [0002] In the current smart city construction, Internet of Things technology has been widely used, such as common public transportation, sewer manhole covers, urban street lighting, smart water meters / electric meters / gas meters and other equipment, all of which are connected and monitored by sensors to collect and transmit data , and in the future, more personal and public facility data will be automatically collected and widely used. The construction of an IoT smart city involves cross-level, cross-department, and cross-device data interconnection. Networking technology is not conducive to the extension and display of smart city construction, and cannot meet the requirements of safety, lo...
