A Blockchain-Based Architecture and Framework for Cybersecure Smart Cities

Abstract

A smart city is one that lowers the cost of municipal services while simultaneously enhancing the quality of life for its residents via the use of digital technology and other strategies. In order to monitor municipal assets and community developments in real time, enhance operational efficiency, and proactively address any issues and obstacles, smart cities largely employ IoT to gather and analyze data. These days, one of the biggest issues confronting smart cities is cyber security. The cyber security research community has given this problem a lot of attention in recent years. Blockchain is starting to emerge as a technology that may help with this difficulty. It provides the data security and secrecy that are necessary to bolster the security of smart cities. In order to enhance the cyber security of smart cities, we provide in this article a thorough framework and architecture based on big data, blockchain, and artificial intelligence. We give simulation results together with analysis and testing to provide a detailed picture of the suggested system. The UCI Machine Learning Repository's smart grid dataset served as the basis for these simulations. The results clearly show the potential and efficacy of the suggested methodology for handling cyber security issues in smart cities. These outcomes support the framework's applicability and usefulness in a practical setting.
