CHIP CARD, AND METHOD FOR THE SOFTWARE-BASED MODIFICATION OF A CHIP CARD

摘要

The invention relates to a chip card, particularly a smart card, comprising an operating system that is implemented on the chip card and controls the functions of the chip card, and a first operating system kernel level which is the nucleus of the operating system and on which the process and data organization of the operating system is defined. A second, uniform operating system kernel level is provided on which first operating system kernel level functions are defined that can be addressed from outside the operating system, and an interface is provided for accessing the second uniform operating system kernel level from outside the operating system. The invention also relates to a method for the software-based modification of such a chip card.
