Abstract

Provided is a method for generating a physical unclonable function PUF response by a PUF circuit of an electronic device, said PUF circuit comprising pairs of electronic components called PUF primitives implementing said physical unclonable function, by obtaining a challenge (S), generating PUF output bits (S) by applying said physical unclonable function to said obtained challenge, and generating said PUF response (S) from said generated PUF output bits verifying υ>δυ+|T| or υ<−δυ−|T| with δυ a predetermined threshold. In some embodiments it maximizes a PUF response entropy based only on the analog differential values generated by the comparators of the electronic device. Other embodiments disclosed.
