Abstract: The invention provides a method for loading an application requiring personalization into a portable storage medium which is set up to be operated in a terminal. Personalization data for personalizing the application and possibly application data are additionally loaded into a restore module which is independent of applications stored in an application memory, is configured as a non-volatile memory, and is disposed within the portable storage medium or within the terminal. For updating an application, the personalization data and possibly application data are loaded from the restore module into the updated application. A portable storage medium has a non-volatile, application-independent restore module. System with storage medium and terminal and non-volatile, application-independent restore module.

Abstract: The invention sets forth an authentication method for use in a system including a first entity and a second entity in a network, the first entity being adapted to authenticate the second entity and data received therefrom, both first and second entities storing the same secret key. The method is implemented in a smart card such as a USIM card, including: a memory storing authentication algorithms and keys; means for receiving a message authenticating code and other parameters; means for computing an expected code from said other parameters and from said secret key; means for comparing said message authenticating code received and said expected code; and means for aborting authentication if the message authenticating code received and the expected code do not match.
