A PROTECTION METHOD AGAINST EEPROM-DIRECTED INTRUSION INTO A MOBILE COMMUNICATION DEVICE THAT HAS A PROCESSOR, AND A DEVICE HAVING SUCH PROTECTION MECHANISM

摘要

For protecting against EEPROM-directed intrusion into a mobile communication device that carries EEPROM memory and a processor, that are interconnected via an interface, the following particular steps are taken: an incipient powering operation of the device is detected; the microprocessor detects an external interfacing master; thereupon, the microprocessor takes a protecting measure for blocking subsequent reading of said EEPROM by the external interfacing master.
