Abstract
A system and method for performing cryptographic functions in hardware using read-N keys comprising a cryptographic core, seed register, physically unclonable function (PUF), an error-correction core, a decryption register, and an encryption register. The PUF configured to receive a seed value as an input to generate a key as an output. The error-correction core configured to transmit the key to the cryptographic core. The encryption register and decryption register configured to receive the seed value and the output. The system, a PUF ROK, configured to generate keys that are used N times to perform cryptographic functions.
