Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The main idea of ​​the present invention: the electronic key sends an unlock command to the electronic lock, and the random sequence generation module of the electronic lock generates a random sequence of a certain length after receiving the unlock command, and sends the random sequence to the ciphertext processing of the electronic lock module and the ciphertext verification module, the ciphertext processing module of the electronic lock encrypts the random sequence according to the preset encryption algorithm, and sends the generated ciphertext to the ciphertext processing module of the electronic key, and the ciphertext processing module of the electronic key reads Take the unlocking key corresponding to the above encryption algorithm stored in the key st...

Abstract

The invention discloses an electronic key and electronic lock, wherein the electronic key contains key storage mode, cryptogram disposal mode and wireless transceiving mode; the electronic lock contains cryptogram checking mode, wireless transceiving mode, random sequence generation mode and cryptogram disposal mode. The unlocking method comprises the following steps: receiving the unlocking order from the electronic key; generation the random sequence; sending the encrypted random sequence to the electronic key; deciphering the unlocking cryptogram according to the stored key cryptogram; sending the deciphered random sequence to the electronic lock; comparing the received random sequence with the original random sequence; opening the lock if consistent; rejecting to open if inconsistent.

Description

technical field [0001] The invention relates to electronic key technology, in particular to an electronic key and electronic lock device and a realization method thereof. Background technique [0002] A wireless electronic key is a device that uses wireless signals as an unlocking key to unlock cars, doors, and safes. [0003] In the existing electronic key and electronic lock device, the electronic key transmits the signal carrying the unlock password to the electronic lock device through the wireless transmission circuit, and the electronic lock usually verifies the received unlock password after receiving the unlock password. Judging whether the user is legal, if legal, then control the electronic lock switch to open, otherwise refuse to unlock. [0004] However, since the electronic key and the electronic lock are separate components, when the user uses the electronic key to open the electronic lock, the wireless signal carrying the unlock code must reach the electronic...
