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 12):
The electronic cryptographic device as in  claim 11 , wherein the statistical parameter includes at least one of:\n the total number of differences between the first and second noisy bit string, the longest run of difference bits in the difference between the between the first and second noisy bit string, and the longest run of non-difference bits in the difference between the between the first and second noisy bit string.
