Mutual Lightweight PUF-Based Authentication Scheme Using Random Key Management Mechanism for Resource-Constrained IoT Devices

This paper presents a novel RF-PUF-based authentication scheme, called RKM-PUF which takes advantage of a dynamic random key generation that depends upon both communication parties in the network to detect intrusion attacks. Unlike the existing authentication schemes, our proposed approach takes the physical characteristics of both involved parties into account to generate the secret key, resulting in securely mutual authentication of both nodes in a wireless network. The experimental results of the proposed authentication scheme show that the RKM-PUF can reach up to 99% in identification accuracy.
