A power supply device is used to provide power to an encryption and decryption device of a security system, including a safety power supply device, which is used to supply the supply voltage according to the system voltage; a regulated voltage source, which is used to provide a regulated voltage; and a voltage selection device, which is electrically connected with the safety power supply device, the stable voltage source and the encryption and decryption device. During the startup period of the security system, or, after the startup period of the security system and the encryption/decryption device performs encryption/decryption, only the supply voltage is selected as the driving voltage of the encryption/decryption device. After the startup period of the security system and the encryption and decryption device does not perform encryption and decryption, the voltage only the regulated voltage is selected as the driving voltage of the encryption and decryption device.

Power supplying device, method and secure system

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.
