Embodiment Construction
[0052] A specific data processing device, that is, an embodiment of an embedded system in the form of a chip card or a smart card that includes an integrated circuit (IC) that can perform cryptographic operations, can refer to the public key system (PKI) system, which The method proposed according to the invention works, ie is protected by a protection arrangement 100 (see FIG. 1 ) against abuse and / or against manipulation.
[0053] This embodiment of a circuit arrangement 100 for electronic data processing is provided for a microcontroller of the embedded security controller type. The circuit arrangement 100 contains a multicomponent non-volatile memory module 10 (so-called non-volatile (NV) memory) in the form of an electrically erasable programmable read-only memory (EEPROM) and can be accessed via This module stores data.
[0054] Associated with this non-volatile (NV) memory module 10 is an interface logic 20 through which,
[0055] - the memory module 10 can be address...
