For this purpose, five different strategies to select a small set of locations out of a big set of locations to construct a PUF have been proposed and compared. The analysis reflects that, depending on the chosen selection strategy, the quality of the PUF can be greatly affected, especially in terms of uniqueness.2022http://zaguan.unizar.es/record/14503510.1109/PRIME55000.2022.9816767http://zaguan.unizar.es/record/145035oai:zaguan.unizar.es:145035info:eu-repo/grantAgreement/ES/AEI/PID2020-114110RA-I00info:eu-repo/grantAgreement/ES/DGA/LMP197-21Conference on Ph.D. Research in Microelectronics and Electronics. 2022 (2022), 361-364All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
