Electronic data processing device suitable for execution of software protected against copying, whereby software is sub-divided with an auxiliary program stocked and executed in a secure chip card reader

摘要

Electronic device for processing data comprises a central unit (UC) for execution of a software application and a reader (16), e.g. a chip card reader. A main program is executed by the central unit, while an auxiliary program is stocked and executed in a secure electronic device, such as a chip card (17) inserted in the reader. An Independent claim is made for: a software medium, such as a CD comprising two units, each containing two parts of the same program, i.e. a main and auxiliary program. The invention also relates to a corresponding electronic device such as a mobile phone or PDA, suitable for accepting such a software medium.
