A PUF-Based Modeling-Attack Resilient Authentication Protocol for IoT Devices

Physical unclonable functions (PUFs) offer a promising solution for the authentication of Internet of Things (IoT) devices as they provide unique fingerprints for the underlying devices through their challenge–response pairs. However, PUFs have been shown to be vulnerable to modeling attacks. In this article, we propose a novel protocol to thwart such vulnerability by limiting the adversary’s abil...
