摘要： Some embodiments relate to an electronic cryptographic device (100) arranged to determine a cryptographic key. The cryptographic device is arranged for an enrollment phase and a later reconstruction phase. The cryptographic device comprising a physically unclonable function (PUF) (110) and a processor circuit. The circuit being configured to determine during the enrollment phase debiasing data (142), first noise reduction data (131) and first noise reduction data. The circuit being configured to during the reconstruction phase compute at least one cryptographic key from first corrected bits and second corrected bits.

摘要： Some embodiments are directed to an electronic cryptographic device arranged to determine a cryptographic key. The cryptographic device can include a physically unclonable function (PUF) arranged to produce a first noisy bit string during the enrollment phase and a second noisy bit string during the reconstruction phase, and a statistical unit arranged to execute a statistical test for verifying correct functioning of the physical unclonable function. The statistical test computes a statistical parameter for the physical unclonable function using helper data. The statistical test determines correct functioning if the statistical parameter satisfies a criterion of the statistical test.

摘要： Some embodiments are directed to an electronic cryptographic device configured to determine a cryptographic key. The cryptographic device has a physically unclonable function, a debiasing unit, and a key reconstruction unit. The PUF is configured to produce a first noisy bit string during an enrollment phase and a second noisy bit string during a reconstruction phase. The debiasing unit (120) is configured to determine debiasing data from the first noisy bit string during the enrollment phase. The debiasing data marks bits in the first noisy bit string as retained or discarded. The key reconstruction unit is configured to determine the cryptographic key from bits in the second noisy bit string marked as retained by the debiasing data, the cryptographic key being independent from bits in the second noisy bit string marked as discarded by the debiasing data.

摘要： An electronic cryptographic device (100) comprising a physically unclonable function (PUF) (110) and an enrollment unit (142) arranged to generate a first PUF data during the enrollment phase, the first PUF data being derived from a first noisy bit string of the PUF, the first PUF data uniquely identifying the physically unclonable function, the first PUF data comprising a first helper data. The first PUF data is transmitted to an electronic server during an enrollment phase. The device comprises a use-phase unit (144) arranged 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 (160) is arranged to apply the first helper data to the second noisy bit string.
