A lightweight authentication protocol for IoT-based cloud environment

With the ever-growing use of active internet devices, the Internet of Things (IoT) has achieved vast popularity at present. Authentication technology is essential for the success of integrating IoT and cloud computing. Recently, the adversary capabilities are enhanced, and the current authentication techniques are vulnerable in plenty of possible network attacks. This paper presents a secure and lightweight authentication protocol for IoT-based cloud environment. The proposed scheme can withstand various attacks and provide secure mutual authentication and anonymity by utilizing secret parameters and biometric. Lightweight crypto modules are adopted to pursue the best energy efficiency. The AVISPA tool is used to evaluate the protocol's performance. The obtained results indicate that the proposed protocol can effectively resist all kinds of known vulnerabilities.
