The advantage of the universal key is that the user does not need to carry a large variety of different keys to open different locks, and the convenience of lifting the large spokes, but the universal key can open different locks, and the danger is relatively If it is stolen or lost, it can be obtained by others, and its people can open different locks. The loss of property will be relatively heavy. Therefore, the design of the universal key must pay special attention to the safety of use. The encryption and decryption of the universal key can enhance the security of its use.

Regarding the technology of switching locks through encryption and decryption, the prior art has also been disclosed, such as the Republic of China new M493578 "ring type electronic code lock system" patent case, which is a ring type electronic cipher key system, including: a ring a key, which is provided with a password digital; an electronic keyhole; a read password digital device disposed around the electronic keyhole; and a processor device provided with a soft and hard device for encrypting and decrypting the password; When the ring key is placed in the electronic keyhole, the read password digital device around the electronic keyhole reads the password number of the ring key; the password number is transmitted to the processor device via the first connection interface; The hardware and software of the device determines the user identity to determine the unlocking action of the password digital processing.

Another example is the patent application of the electronic password lock system and its unlocking method of the Republic of China No. 201309882, which discloses an electronic code lock system including a lock head and a USB key, the lock head including a first USB interface, an input device and The control module is configured to input a password, and the control module is configured to control unlocking of the lock.
