In this paper, an introduction to Physically Unclonable Functions is given, including their definition, properties and applications. Finally, as an example of how to design a PUF, the general structure of a ring oscillator PUF is presented.2020http://zaguan.unizar.es/record/10831910.1109/ECCTD49232.2020.9218404http://zaguan.unizar.es/record/108319oai:zaguan.unizar.es:108319info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-RIEEE ...
