  "textContent": "A power supply device for providing a driving voltage of an encryption/decryption device. When the encryption/decryption device is in operation and its driving voltage falls within the voltage range formed by an upper limit voltage and a lower limit voltage, only a supply voltage provided by a secure power supply device is used as the driving voltage for the encryption/decryption device. When the encryption and decryption device is in operation and its driving voltage falls outside the voltage range formed by the upper limit voltage and the lower limit voltage, the supply voltage and a stable voltage provided by the stable voltage source are used as the driving voltage at the same time, the supply voltage is further adjusted until the driving voltage falls within the voltage range formed by the upper limit voltage and the lower limit voltage, and then continue to use only the supply voltage as the driving voltage.",
