Security Enhancement for IoT using Mutual Authentication Based Lightweight Algorithm

Internet of Things (IoT) has revolutionized communication technology by enabling seamless data exchange between devices. As the proliferation of sensors and smart devices grows, IoT services become increasingly accessible, impacting our lives in diverse areas such as homes, offices, agriculture, and healthcare. However, the widespread adoption of IoT also raises critical concerns regarding data security, device privacy, and the integrity of underlying infrastructure. To address these challenges, robust authentication mechanisms are essential. Mutual authentication between IoT devices establishes trust and confidence, facilitating secure data sharing and integration of diverse IoT ecosystems. This article proposes a lightweight security protocol for IoT devices that leverages fog-based computing to ensure mutual authentication and protect against well-known attacks. Through rigorous mathematical analysis, the proposed protocol is demonstrated to be resistant to various security threats.
