Blockchain technology-based framework to build cyber-secured smart cities

Abstract

The recent surge in population growth is driving an escalating demand for resources, propelling the imperative for Internet of Things (IoT)-enabled devices in the evolution of smart cities. “Smart city” is an umbrella term that spans smart homes, smart waste management, smart drainage management, smart transport, and smart traffic management systems with accessible Wi-Fi and surveillance. There is a revolution in IoT-based urban services, and along with the burgeoning data volumes stored in the cloud for smart city operations, considerable challenges have been identified, primarily concerning privacy breaches and information leaks. The future of urbanization is critically dependent on cloud security for storing billions of data points. The transformative potential of smart cities presents unprecedented cyber threats that can compromise crucial services and infrastructure. Mitigating these cyber risks necessitates a hybrid persuasive intelligent security system with blockchain technology. Blockchain technology delivers secure, traceable, and decentralized techniques for storing and transmitting data. Nevertheless, successful utilization of blockchain demands careful contemplation of scalability, energy efficiency, and interoperability. Striking a balance between innovation and security, along with collaborative efforts between stakeholders, is pivotal for harnessing the transformative power of smart cities while ensuring robust data protection and urban resilience.
