Physical Unclonable Functions (PUF) and True Random Number Generators (TRNG) are two very useful components in secure system design. PUFs can be used to extract chip-unique signatures and volatile secret keys, whereas TRNGs are used for generating random padding bits, initialization vectors and nonces in cryptographic protocols.
