Abstract
With the rapid development of the Internet of Things (IoT), the number of device connections has increased exponentially, and security issues have become increasingly prominent. The traditional security mechanism is difficult to deal with the security threats of massive heterogeneous equipment access, data transmission and storage. Blockchain technology provides a new solution for Internet of Things security with decentralization, tamper-proof and traceability. This study aims to explore the block chain technology application in the field of Internet of things security, through the analysis of Internet security challenges, combining with the characteristics of block chain technology based on alliance chain architecture Internet security fr amework, the fr amework of identity authentication, permission management, data encryption and other key technologies, effectively solve the Internet of things equipment identity forgery, data tampering and privacy problems. The method of combining simulation test and actual scenario deployment is adopted to verify the effectiveness of the proposed scheme, and is tested in typical application scenarios such as smart home and industrial Internet. The results show that the fr amework can significantly improve the security and reliability of the Internet of Things system and reduce the incidence of security events.
