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 7):
The electronic cryptographic device as in  claim 6 , wherein the error correcting code is a concatenated error correction code for which the most inner code is a repetition code, the series of code words of an error correcting repetition code being selected by selecting one or more code words from the concatenated error correcting code.
