Zusammenfassung:A method for determining a key for securing communication between a user apparatus and an application server. An authentication server of a mobile communication network and the user apparatus generate a secret master key during an authentication procedure. The user apparatus sends the authentication server a request for a key to communicate with the application server and receives a random variable. The authentication server and the user apparatus calculate the requested key by using a key derivation function applied to at least the random variable, a user identifier and an application server identifier using the master key.
