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 9):
The electronic cryptographic device as in  claim 8 , wherein the first statistical test includes:\n counting the number of determined Hamming weights that are above an upper Hamming weight threshold or below a lower Hamming weight threshold, and determining if the bias of the physical unclonable function is within an allowable bias range if the counted number is within an allowed counted Hamming weight range.
