Abstract: The invention relates to a method for masking the end-of-life transition of an electronic microprocessor device comprising a reprogrammable non-volatile memory containing an end-of-life state variable (FdVE). The value of the variable (FdVE) is loaded (A) into random access memory. Prior to the execution of any current command (COM), the value of the variable (FdVR) in random access memory is checked (B). The end-of-life transition is executed (C) in the event of an empty value. Otherwise, the initialization or the execution of the command (COM) is continued (D). Upon detection (E) of an intrusive attack, the end-of-life state variable (FdVR) is written (F) in the single random-access memory, and the end-of-life state variable (FdVE) is deleted (G) from the non-volatile memory in a delayed manner. The invention is suitable for all electronic devices, microprocessor cards or the like.

Abstract: A method of masking the end-of-life transition of a microprocessor electronic device including reprogrammable non-volatile memory containing an end-of-life state variable. On booting, the value of the variable is loaded into RAM. After executing any current command, it is verified whether the value of the variable stored in RAM is FALSE. If the response is negative, the end-of-life transition is executed. Otherwise, initialization or execution of the command is continued. On detecting an intrusive attack, it is instantiated by writing the TRUE value to the end-of-life state variable in RAM only and then deferring writing of the TRUE value to the variable in the non-volatile memory until the next write operation. The invention is applicable to any electronic device, smart card, etc.

Abstract: A method of securely transferring data. The source data stored in a source memory (NV_MEM) is compared with the transferred data (COPY_ELT_X_V_MEM) that has been copied from the source memory (NV_MEM) into a “destination” memory (V_MEM). The method consists in reading from the source memory (NV_MEM) an integrity value (PI_ELT_X) associated with an element (ELEMENT_X_NV_MEM) such as file containing the source data, in calculating the integrity of a reconstituted element made up of the transferred data (COPY_ELT_X_V_MEM) associated, where appropriate, with the data of the source element (ELEMENT_X_NV_MEM) other than the data that was transferred, and in deciding that the transferred data (COPY_ELT_X_V_MEM) is identical to the source data when the integrity calculation gives a value identical to the integrity value of the source element (PI_ELT_X). The method applies to transferring data between components of a smart card.
