Authentication schemes for Internet of Things (IoT) networks: A systematic review and security assessment

Internet of Things (IoT) networks are revolutionizing various aspects of our lives by enabling intelligent and automated systems. However, the proliferation of IoT devices also presents significant security challenges, particularly in terms of privacy and information security. Authentication, a fundamental security mechanism, is crucial to protecting IoT devices and the sensitive data they exchange. This work provides a comprehensive review of authentication schemes for IoT devices, analyzing their strengths, weaknesses, and security considerations. We delve into the formal and informal security evaluations of these schemes, as well as their performance metrics in terms of computational overhead, communication cost, and energy consumption. By comparing/contrasting different authentication approaches, we identify potential areas for improvement and highlight the need for robust, efficient, and secure authentication solutions tailored to the unique requirements of IoT networks. This review aims to guide IoT researchers and practitioners in developing innovative authentication schemes, particularly for resource-constrained IoT devices, that can address the evolving security landscape of IoT.
