A Secure Communication Framework for Smart City Infrastructure Leveraging Encryption, Intrusion Detection, and Blockchain Technology

Abstract

Smart cities, characterized by interconnected devices and data-driven services, are increasingly vulnerable to cyberattacks. This paper proposes a comprehensive security framework tailored to address the unique challenges of smart city communication networks. We delve into the evolving threat landscape, identifying potential vulnerabilities and attack vectors. The proposed framework integrates advanced encryption protocols, multi-layered intrusion detection systems (IDS), and blockchain technology to ensure data integrity and traceability. We discuss implementation challenges, and potential solutions, and evaluate the framework's effectiveness through simulations and case studies. Our research emphasizes the critical need for continuous monitoring, adaptation, and a proactive approach to cybersecurity in the dynamic smart city environment.
