摘要： Some embodiments relate to an electronic cryptographic device (100) 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) (110) and a processor circuit. The circuit being configured to determine during the enrollment phase debiasing data (142), first noise reduction data (131) 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.

摘要： Some embodiments are directed to an electronic cryptographic device including a physically unclonable function and an enrollment unit configured to generate a first PUF data during the enrollment phase, the first PUF data derived from a first noisy bit string of the PUF, the first PUF data uniquely identifying the physically unclonable function, the first PUF data including a first helper data. The first PUF data is transmitted to an electronic server during an enrollment phase. The device includes a use-phase unit configured to generate a second PUF data derived from a second noisy bit string during a use phase. The first helper data is received from the server in response to transmitting the second PUF data. An error corrector is configured to apply the first helper data to the second noisy bit string.

摘要： The present invention relates to a method of enabling authentication of an information carrier, the information carrier comprising a writeable part and a physical token arranged to supply a response upon receiving a challenge, the method comprising the following steps; applying a first challenge to the physical token resulting in a first response, and detecting the first response of the physical token resulting in a detected first response data, the method being characterized in that it further comprises the following steps; forming a first authentication data based on information derived from the detected first response data, signing the first authentication data, and writing the signed authentication data in the writeable part of the information carrier. The invention further relates to a method of authentication of an information carrier, as well as to devices for both enabling authentication as well as authentication of an information carrier.
