Blockchain-based IoT device identity authentication and data traceability

Abstract

With the advent of the Internet of Things (IoT) era, IoT data has become increasingly important. Due to risks such as data forgery in network data, there is an even greater need for identity authentication and data traceability. In response to this, a research proposal for IoT device identity authentication and data traceability based on blockchain technology has been designed. First, by combining IoT devices with blockchain technology, the technical approach for IoT device identity authentication and data traceability is determined. Then, using development tools, the proposed technical approach is designed and implemented. Finally, the proposed research solution is subjected to empirical analysis from multiple dimensions. Under the proposed traceability method, as data volume increases, the time overhead approaches zero, with a traceability tracking time range of 280–300 ms and minimal variability, indicating that the proposed research solution demonstrates excellent practical effectiveness.
