Secure And Lightweight Authentication Protocols For Devices In Internet Of Things

Abstract

The proliferation of Internet of Things (IoT) devices has led to an unprecedented level of connectivity, transforming the way we interact with the digital world. As the IoT ecosystem expands, ensuring the security of communication between devices becomes paramount. This paper presents a comprehensive exploration of secure and lightweight authentication protocols designed specifically for IoT devices. In contrast to traditional authentication methods, IoT devices often operate under resource-constrained environments, with limited processing power, memory, and energy. Consequently, conventional authentication protocols may prove impractical, leading to vulnerabilities that can be exploited by malicious entities. Recognizing this challenge, our research focuses on the development of authentication mechanisms that strike a balance between robust security and minimal resource overhead. The proposed protocols leverage advanced cryptographic techniques to provide a secure foundation for device authentication while mitigating the computational burden on resource-constrained IoT devices. We analyse the strengths and weaknesses of existing authentication protocols and identify opportunities for improvement. Additionally, our research introduces novel approaches that optimize authentication processes, ensuring efficiency without compromising security.
