Enhancing Network Security and Efficiency in Smart Cities: SDN-Based Hashing Authentication

In contemporary society, technological devices have seamlessly integrated into our daily routines, becoming indispensable components that optimize time and energy consumption. Among these technologies, Artificial Intelligence (AI) and the Internet of Things (IoT) have revolutionized various aspects of life, elevating speed, convenience, and efficiency. However, this reliance on technology has brought forth security concerns that permeate every sector, impacting the network as a whole. This study proposes a solution employing a hashing mechanism for authentication using SHA-256 and implementing the SDN controller for streamlined network operations and detection of potential threats. To address this issue, the development of a comprehensive system capable of authenticating nodes, effectively routing data packets, monitoring network behavior, and detecting malicious nodes is imperative. This is to examine critical aspects necessary to achieve a robust and secure network infrastructure. This results in effective and efficient detection, routing and maintainability of the network while keeping the throughput low avoiding delay in performance and adaptive to most situations.
