Multi-Voltage PUF DataSet

This dataset contains Challenge-Response Pairs (CRPs) from Ring Oscillator-based Physical Unclonable Functions (RO-PUFs) operating under constant and variable voltage conditions. Collected from three chips fabricated in a 22nm FDSOI process and powered by a Switched-Capacitor DC-DC converter, it includes two sections: responses at a fixed voltage and across nine voltage levels (nominal and ±10% variations). Organized into ten folders, the dataset includes 1K CRPs per chip for each voltage and a combined folder with 20K CRPs. All data is stored in hexadecimal format, with a subset of concatenated 128-bit responses for further analysis. This dataset enables evaluation of voltage-aware hardware security primitives and supports research in PUF reliability and machine learning modeling.
