Abstract: An electronic device includes a power supply unit, a control unit, a first boot circuit, and a data encryption unit. The control unit outputs a boot signal for causing the power supply unit to start supplying power. The first boot circuit interconnects the power supply unit and the control unit for transmitting the boot signal. The data encryption unit is for interconnecting the power supply unit and the control unit so as to form a second boot circuit through which the boot signal is transmitted and for cutting off the first boot circuit.
