<p>The invention relates to a method on a terminal (T) comprising at least one security element (SE) and a first secure execution environment for executing security relevant applications (SApp1, SApp2), and a second non-secure execution environment. An application (SApp1, SApp2) relevant to security is executed in the secure execution environment, wherein the application (SApp1, SApp2) uses a variable (C1, C2) and stores the same in a non-volatile manner. A dedicated interface of the secure execution environment is used, provided for security relevant applications, for swapping out variables on the security element, in order to store the variables via the security relevant application (SApp1, SApp2) in the at least one security element (SE).</p> |
