Authentication Framework for an IoT Ecosystem

The rapid development of the Internet of things (IoT) in different industrial sectors and medical field. The growth of these devices also raises security issues in IoT devices. The problems are in terms of device authentication and static key storage. We cannot implement any protocol directly in the IoT devices because of constrained devices and low computational power, which is a challenging task. We proposed the authentication framework based on Shamir Secret key sharing. We implemented this authentication between Gateway and edge node. This scheme avoids static key storage. We implemented this scheme on ESP32 as edge node and Orange Pi and Calculated Gateway power and current consumption, showing that our scheme impacts the device minimally. Further, we analyzed the security analysis using the AVISPA tool and our proposed protocol resistant to man-in-the-middle attack (MITM), cloning attack, and replay attacks; also, we conducted a comparative analysis and also security protocols with existing protocols, which proved that my proposed scheme is highly secure and lightweight which is feasible for all IoT environments.
