Abstract:
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.

Claim (Index 16):
The electronic cryptographic method as in  claim 15 , further comprising an enrollment phase and a later reconstruction phase,\n the enrollment phase including:\n producing the first noisy bit string with the physically unclonable function (PUF), and \n generating helper data from the first noisy bit string during the first phase, the helper data allowing reconstruction of the first noisy bit string from the helper data and a second noisy bit string produced by the PUF during reconstruction phase, and \n the reconstruction phase including:\n producing the second noisy bit string with the physically unclonable function (PUF), \n wherein\n the enrollment or reconstruction phase includes executing the statistical test.
