Abstract: The paper designs and studies a 5G-based smart city IoT architecture, focusing on data management and analysis methods as well as security and privacy protection technologies. In the architecture design, by introducing multi-level data processing mechanisms and complex security protection systems, the problem of efficient processing and transmission of multi-source heterogeneous data in smart cities is solved. At the same time, this article proposes a security architecture that integrates identity authentication, data encryption, privacy protection and threat detection, and analyzes the principles of data stream processing in detail through mathematical models. Analysis shows that this architecture has significant advantages in improving smart city management efficiency, ensuring system security and privacy protection. Although it still faces challenges such as high infrastructure costs and limited network coverage, the prospects of its application in future smart city construction are bright.
