Storing data objects in a smart card memory

摘要

The invention refers to a method for storing data objects 210, 220, 230, 240 in the memory 200 of a smart card 100. To do this, general and application-specific data objects are defined using freely selectable security characteristics and access rights, which are filed in the memory of a smart card which is divided into several application-specific memory areas 110, 120 so that data objects with identical access conditions are located in one and the same memory area, irrespective of the application program 310, 320, 330 or smart card user 400 to which these data objects are allocated. All application programs and the smart card user can access the data objects irrespective of the corresponding access conditions. In this way, the re-issuing of smart cards in the case of later expansion of the file structure of the smart card for an application or the addition of extra applications is not necessary. The smart card user can allow any applications to store data on his smart card.
