Abstract

See full text

A method for setting up a subscriber identity module for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server includes generating one or several exchange keys from keys of the provisioning server and of the subscriber identity module on a production server and are transmitted into the subscriber identity module and stored, so that the subscriber identity module is put particularly into a state as though it had generated the exchange keys itself. In a method for agreeing one or several exchange keys, between a subscriber identity module and a provisioning server, the subscriber identity module sends its public key to the provisioning server, which subsequently generates the exchange keys.
