Abstract
Some embodiments are directed to an electronic cryptographic device including a physically unclonable function and an enrollment unit configured to generate a first PUF data during the enrollment phase, the first PUF data derived from a first noisy bit string of the PUF, the first PUF data uniquely identifying the physically unclonable function, the first PUF data including a first helper data. The first PUF data is transmitted to an electronic server during an enrollment phase. The device includes a use-phase unit configured to generate a second PUF data derived from a second noisy bit string during a use phase. The first helper data is received from the server in response to transmitting the second PUF data. An error corrector is configured to apply the first helper data to the second noisy bit string.
