Cuiyun Chen, Yanru Chen, Yue Gong · 2023
In recent years, the Internet of Things industry has developed rapidly, and various intelligent devices have been connected to the Internet of Things, gradually improving people's daily lives. With the continuous increase in the number of Internet of Things devices, the resulting user privacy data is also exploding, ensuring information security is very important. Decentralized blockchain technology involves disciplines such as computer programming and cryptography, and is a distributed database. Compared to traditional information technology, blockchain has significant technical advantages in information disclosure and transparency. This article builds a blockchain based IoT management platform based on the Hyperledger Fabric framework. The platform uses blockchain as the underlying technology, cooperates with storing source data to the IPFS network, uploads the returned hash value to the blockchain network, and applies blockchain technology to the field of information security. Combining the application characteristics of the technology, it provides a new solution for solving the information security issues of the Internet of Things.
