摘要： The invention relates in particular to an electronic device equipped with a virtual machine for executing an applet. The virtual machine is arranged so as to recognize the instructions of the applet and to execute a code corresponding to each instruction. The virtual machine comprises an association module arranged so as to associate several distinct but operationally identical codes with one and the same instruction, and a selection module arranged so as to select the code to be executed for said instruction in a random manner. The invention also relates to a method of securing a counter-electronic device against hidden-channel attacks.

摘要： 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.
摘要翻译：本发明涉及一种用于掩蔽电子微处理器装置的寿命终止过渡的方法，包括包含报废状态变量（FdVE）的可编程非易失性存储器。变量（FdVE）的值被加载（A）到随机存取存储器中。在执行任何当前命令（COM）之前，检查随机存取存储器中变量（FdVR）的值（B）。在空值的情况下执行生命周期过渡（C）。否则，继续执行命令（COM）的初始化或执行（D）。在侵入性检测（E）中，在单个随机存取存储器中写入寿命终止状态变量（FdVR）（F），并将生命周期状态变量（FdVE）删除（G ）从延迟的方式从非易失性存储器。本发明适用于所有电子设备，微处理器卡等。
