Abstract
The invention relieves an application programmer of the responsibility for managing access rights, by providing application code that is independent of the protection in a chip card. When an application, for example in a docking station, is given access to an object pertaining to another application in a chip card, two capabilities are created respectively in the applications, as objects, to protect all subsequent accesses to the object by filtering them through the two capabilities. On accessing an object pertaining to an application, if a second object pertaining to the other application is passed on to the latter, two other capabilities are added in the applications to protect access to the second object.
