Abstract: For configuring and installing access control devices at an installation site, configuration data for unidentified access control devices of the installation site is stored (S10) in a cloud-based computer system (1). The cloud-based computer system (1) receives (S2) a registration assigning the installation site to a media identifier stored in a setup media device. A particular one of the access control devices (4) at the installation site reads (S40) the media identifier stored in the setup media device (5). The media identifier from the particular access control device (4) is received (S5) in the cloud-based computer system (1). In the cloud-based computer system (1), the particular access control device (4) is mapped to one of the unidentified access control devices of the installation site. The configuration data of the mapped access control device is transmitted (S80) from the cloud-based computer system (1) to the particular access control device (4).

Abstract: An identification system includes at least one user medium, which is equipped to store a derived key and authenticate itself using the same with respect to a write and/or read device. Furthermore, at least one key dispensing medium is present, which comprises a monolithic first integrated circuit having storage means and processor means, wherein the first integrated circuit is equipped to store a source key and derive therefrom the derived key and to pass it on for storage in the user medium, wherein the user medium is enabled neither directly nor by way of aids to read the source key from the key dispensing medium and/or the user medium is not enabled to calculate a derived key.
