En IEEE European Conference on Circuit Theory and Design, ECCTD 2020 (9218444-), Sofia, Bulgaria: Institute of Electrical and Electronics Engineers.978-1-7281-7183-82474-96722472-467Xhttps://hdl.handle.net/11441/169031This paper describes a circuit structure named RO-PUF-TRNG based on ring oscillators (ROs), which is able to be calibrated to perform as a physically unclonable function (PUF) and a true random number generator (TRNG) with high uniqueness, entropy, and throughput. The calibration is based on a mathematical model that describes how the PUF and TRNG response bits are related to the intrinsic variations of the fabrication process and bitstream generation (in the case of FPGAs) as well as to the Gaussian noise. The results obtained with the proposed calibration are illustrated with the large dataset of RO frequencies from 90-nm FPGAs provided in [1].application/pdf5 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/CalibrationPUFRing oscillatorTRNGinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1109/ECCTD49232.2020.9218444
