Abstract
A method for introducing an identity into a secure element includes an operating system loaded into the secure element, which comprises a master key which is identical for a plurality of secure elements. A secure-element key datum is generated employing the master key. The secure-element key datum is configured as a temporary secure-element key datum, which, upon an initial authentication of the secure element vis-à-vis the background system, is replaced by a final secure-element key datum which is independent of the master key by employing the temporary secure-element key datum and is itself rendered invalid for further authentications.
