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 18):
The method as in  claim 16 , wherein\n the statistical test includes a second statistical test, the second statistical test being executed during the reconstruction phase using the helper data generated during the enrollment phase, the reconstruction phase further including:\n reconstructing the first noisy bit string from the second noisy bit string and the helper data, and \n determining differences between the first and second noisy bit string, the second statistical test determining the statistical parameter from the differences.
