ABSTRACT:
A method for protecting against EEPROM-directed intrusion into a mobile communication device by an external interfacing master in which an incipient powering operation of the device is detected. The mobile communication device carries an EEPROM and a microprocessor that are interconnected via an electrical interface. The microprocessor detects whether the external interfacing master tries to fraudulently access the EEPROM through the electrical interface. Upon such a detection, the microprocessor undertakes a protecting measure for blocking subsequent reading of the EEPROM by the external interfacing master.
