An Energy-Efficient Multiple-Factor Authentication Protocol for Critical Infrastructure IoT Systems

The Internet of Things (IoT) is an innovative concept aimed at offering an extensive range of applications that have become integral to our everyday existence. In recent decade, cyber-attacks are a major barrier to the adoption and development of critical infrastructure IoT systems. In this paper, we proposed a lightweight, secure, and energy-efficient authentication protocol with session key establishment. The protocol preserves user anonymity to safeguard users' privacy. We developed a multiple-factor authentication protocol in order to provide high resilience for critical infrastructures. According to security analysis, our hash-based scheme is robust against a large number of conventional and quantum computer attacks. We demonstrated our protocol outperforms the baseline mechanisms regarding computation cost, communication cost, and power consumption.
