Problems solved by technology

[0002] The traditional combination lock adopts the simple replacement and replacement of the plaintext and ciphertext in the form of a password table, and the key of the lock is fixed once the lock is produced, which is not flexible. As long as one of the similar products is cracked, other products will be locked. was breached at the same time

Embodiment Construction

[0004] By CPU, memory, USB controller / transceiver (or SD bus or SPI bus to access SD card), infrared transceiver, Flash memory, interrupt controller, clock circuit, power supply, motor (or solenoid valve) and motor (or solenoid valve) Valve) interface, drive circuit, circuit board, etc. constitute the lock body, and the lock tongue is composed of a motor-driven pendulum mechanism (or a motor-driven gear, and a gear-driven rack) to convert the curved motion into a reciprocating motion (or a solenoid valve for reciprocating motion) movement composition).

[0005] The key is composed of CPU, memory, USB controller / transceiver (or use SD bus or SPI bus to access SD card), infrared transceiver, Flash memory, interrupt controller, clock circuit, power supply, circuit board, casing, and buttons.

[0006] When there is no signal input for a long period of time, the lock and key will automatically switch to the sleep power saving state.

[0007] First, the user enters an encryption al...

Abstract

The present invention relates to an enciphering and deciphering process of cipher lock, belonging to the field of electronic technology. It is characterized by that the crypto key made up by user self can be stored on the mobile storage device of U-disk or SD card by adopting file form, then said crypto key can be respectively transferred onto the lock body and key, said lock body can produce a series of random plaintext according to the crypto key, the plaintext can be converted into cipher text by means of crypto key, said cipher text can be sent into the key by means of lock body, on the key a correspondent cipher technique is adopted, the above-mentioned cipher text also is converted into plaintext, said plaintext can be sent into the lock body by means of key, said lock body can compare the received plaintext with originally-produced plaintext, when the received plaintext meets the requirements, the mechanical portion of said lock can be controlled.

Description

(1) Technical field [0001] The invention relates to a working process of encryption and decryption of a password lock, which belongs to the field of electronics. (2) Background technology [0002] The traditional combination lock adopts the simple replacement and replacement of the plaintext and ciphertext in the form of a password table, and the key of the lock is fixed once the lock is produced, which is not flexible. As long as one of the similar products is cracked, other products will be locked. was breached at the same time. (3) Contents of the invention [0003] Store the user-made key in the form of a file on a mobile storage device such as a U disk, SD card, and then transfer it to the lock body and the key respectively. The lock body generates a series of random number plaintext according to the key, and the key The plaintext is changed into ciphertext, and the lock body sends the ciphertext to the key. Due to the use of symmetric encryption technology on the ke...
