Abstract: The growing reliance on IoT demands secure, lightweight, and tamper-resistant authentication mechanisms. This work implements a Ring Oscillator Physically Unclonable Function (RO-PUF) on a Nexys A7 FPGA to generate unique challenge–response pairs (CRPs) without storing keys in memory. A 128-bit secret key was derived and tested for uniqueness, reliability, and entropy. Machine learning attacks, including Logistic Regression, SVM, and DNN, achieved near-random accuracy, proving resilience. The design offers a low-cost, scalable solution for IoT authentication and cryptographic key generation.
