Abstract
In some aspects, a method includes obtaining, by a response generator circuit, reliability information for each bit of an array of bits provided by a physical unclonable function (PUF) circuit; receiving, from the PUF circuit during run time, an array of values for the array of bits; selecting a plurality of values from the array of values received from the PUF circuit in accordance with the reliability information; and generating, by the response generator circuit, a PUF response from the selected plurality of values.
