Embodiment Construction

[0055] In order to solve the above technical problems, the general idea of ​​the technical solutions in the embodiments of the present invention is as follows:

[0056] An unlocking method and device are provided, and the unlocking method includes:

[0057] When the mobile terminal enters the detection range of the electronic lock, detecting whether the first NFC information in the mobile terminal matches the NFC information stored in the electronic lock;

[0058] if it matches, sending the first key to the mobile terminal;

[0059] Receive and save the second NFC information sent by the mobile terminal, the second NFC information is obtained by the mobile terminal using the first key to encrypt the NFC information stored in the mobile terminal, and the second NFC information is obtained by encrypting the NFC information stored in the mobile terminal with the first key. Judging whether to perform an unlocking operation when the electronic lock enters the detection range next ...

Abstract

The invention discloses an unlocking method and an electronic lock. When detecting that first NFC information in a mobile terminal is matched with NFC information stored in the electronic lock, the electronic lock sends a first key to the mobile terminal, and the mobile terminal can utilize the first key to encrypt the NFC information in the mobile terminal to obtain second NFC information, so that in an unlocking process except first unlocking, the first NFC information detected by the electronic lock is the encrypted second NFC information in the previous unlocking process; an existing technical means of copying the NFC information cannot copy the encrypted NFC information and the key; and due to the fact that the encrypted NFC information stored in the mobile terminal cannot be copied,the method can effectively prevent others from utilizing the copied NFC information in the mobile terminal to perform unlocking, so that the technical effect of improving the security of unlocking byan NFC function is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent door lock control, in particular to an unlocking method and an electronic lock. Background technique [0002] Near field communication (NFC) allows contactless point-to-point data transmission between electronic devices. For example, through NFC technology, short-range wireless can be achieved between mobile terminals, consumer electronics, computers and other electronic devices. communication. Due to the short communication distance and short response time of NFC, compared with other short-range communication technologies (such as Bluetooth technology, infrared transmission technology, radio frequency identification technology, etc.), NFC has the characteristics of high security, low energy consumption, and simple operation. NFC is also used for passive electronic tags, among which electronic tags are often used in various access control cards, campus cards, elevator cards, card keys for ele...
