Abstract: The present invention relates to a method for making available a security key, wherein a smart card adapted according to the invention is employed for the production thereof. In this case, an expedient method sequence is proposed which makes it possible for the smart card to make available, for example, a so-called one-time password or a dynamic check number in interaction with a token server. The present invention further relates to a correspondingly adapted computing arrangement and to a computer program product with control commands which implement the method and/or operate the computing arrangement.

Abstract: The invention relates to a method for carrying out a two-factor authentication between a client and a relying party, wherein, as the second factor, a data carrier is employed which carries out a communication with a token server.

Abstract: A method is provided for carrying out a cryptographically secured authentication which complies with the Universal Authentication Framework (UAF) of the FIDO Alliance. It is thus possible to employ an existing infrastructure of the FIDO Alliance and the method can be embedded into the infrastructure using standard interfaces.

Abstract: A method for personalizing a portable data carrier having a chip provided in a body of the portable data carrier. A portable data carrier whose chip contains data for personalizing the body of the portable data carrier is provided to a personalization unit. The personalization unit receives the data for personalizing the body of the portable data carrier from the chip of the supplied portable data carrier, and personalizes the body on the basis of the received data.
