The secure element further has a secure control unit which is configured to firstly generate a session subscriber authentication key, e.g., during getting the identity of the secure element, and, based on receiving an authentication request from a core network entity, to authenticate the secure element to the core network entity using the previously generated session subscriber authentication key. Furthermore, a terminal device includes the secure element, a system comprising the terminal device, and a core network entity and corresponding methods of the secure element, the terminal device, and the system.
