Abstract
Described herein are methods and systems implementing physically unclonable functions (PUFs). An example method includes: inputting a first challenge bit string into a first PUF; capturing a first response bit string from the first PUF; inputting a second challenge bit string into a second PUF; capturing a second response bit string from the second PUF; performing a hash operation on the first response bit string and the second response bit string, the hash operation generating a hashed-response bit string; and storing the first and second challenge bit strings and the hashed-response bit string in a first database.
