Abstract
Some embodiments relate to an electronic cryptographic device () arranged to determine a cryptographic key. The cryptographic device is arranged for an enrollment phase and a later reconstruction phase. The cryptographic device comprising a physically unclonable function (PUF) () and a processor circuit. The circuit being configured to determine during the enrollment phase debiasing data (), first noise reduction data () and first noise reduction data. The circuit being configured to during the reconstruction phase compute at least one cryptographic key from first corrected bits and second corrected bits.
