Abstract
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.
