Summary: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 (S1), generating PUF output bits (S2) by applying said physical unclonable function to said obtained challenge, and generating said PUF response (S3) 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.
