Secure, light‐weight and dynamic PUF‐based mutual device authentication mechanism in industrial IoT networks

Abstract

Security, a fundamental concern in the design and implementation of industrial Internet‐of‐Things (IIoT) networks, can be addressed through an effective authentication mechanism. Because the devices' battery, CPU, and memory are finite resources, any method designed for the IIoT must be resource sensitive. Our paper discussed a mechanism for device mutual authentication in IIoT networks that is adaptable, lightweight, safe, and efficient. In the proposed mechanism, the devices receive a primary secret value and physical unclonable function‐challenge/response pair (PUF‐CRPs) from the server and employ these values to authenticate one another. Later, IIoT devices requests server to update PUF‐CRPs for future communication We employed one‐way hash function, concatenation operation, XOR operation, and PUF‐CRPs to take into account the resource constraints of the devices. It has been established that the proposed mechanism is immune to well‐known attacks after it has undergone a formal evaluation for safety through BAN logic, and automatic validation through AVISPA and ProVerif tools. Comparative evaluation of the existing mechanisms and the proposed mechanism demonstrated that our proposed mechanism is superior to existing mechanisms, and its experimental study revealed that it uses 28% less energy. Our proposed mechanism is more secure and effective in terms of computing, communication, and storage overheads.
