Problems solved by technology

In this communication process, since the password is directly transmitted between the two, even if the password to open the door is encrypted, it is often encrypted and decrypted using a fixed algorithm. Therefore, once the encryption key is maliciously intercepted by hackers, etc., it will always Obtain the door-opening password for the transmission between the two, so there are certain security risks

Embodiment 1

[0037] Please refer to figure 1 , this embodiment proposes a door lock password management system 100, which can be applied to the generation and management of door lock passwords in places such as residential quarters and apartments. Such as figure 1 As shown, the door lock password management system 100 includes a cloud server 10 and at least one door lock 20 , and each door lock 20 is communicatively connected to the cloud server 10 . In this embodiment, each door lock 20 is assigned a unique device serial number for uniquely identifying the corresponding door lock.

[0038] The cloud server 10 is used to respond to a door lock password acquisition request initiated by a terminal, the door lock password acquisition request includes a unique door lock device serial number and password aging information, and sends a request to the corresponding door lock 20 according to the device serial number A password generation request including the password aging information is initia...

Embodiment 2

[0063] Please refer to figure 1 and image 3 , this embodiment proposes a door lock password management method, which can be applied to the door lock password management system in the above-mentioned embodiment 1, and the door lock password management system includes a cloud server and at least one door lock. The method mainly includes the following steps.

[0064] Step S10, the cloud server responds to the door lock password acquisition request initiated by the terminal, the door lock password acquisition request includes the unique door lock device serial number and password aging information, and initiates a request to the corresponding door lock according to the device serial number to include A password generation request for the password aging information.

[0065] Step S20, the door lock generates a random sequence in response to the password generation request, and sends the random sequence to the cloud server.

[0066] Step S30, the cloud server generates a door lo...

Abstract

The invention discloses a door lock password management system and method. The system includes: at least one door lock and a cloud server. The cloud server is used to respond to a door lock password acquisition request initiated by a terminal. The door lock password acquisition request includes a unique door Lock device serial number and password aging information, initiate a password generation request including password aging information to the corresponding door lock according to the device serial number; the door lock is used to respond to the password generation request, generate a random sequence and send the random sequence to the cloud server; The server is also used to generate a door lock password according to the preset algorithm according to the equipment serial number, random sequence and password aging information of the door lock, and send it to the terminal for the user to input to open the door. According to the technical solution of the present invention, the dynamic generation and management of the door opening password at the door lock end can be realized. By transmitting the password factor between the cloud and the door lock end, the direct transmission of the password between the door lock and the cloud is avoided, and the system security can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent door locks, in particular to a door lock code management system and method. Background technique [0002] In the current smart door lock system, the door opening password of the smart door lock is usually generated by the cloud server, and then sent to the door lock device to verify whether the password entered by the user is correct. In this communication process, since the password is directly transmitted between the two, even if the password to open the door is encrypted, it is often encrypted and decrypted using a fixed algorithm. Therefore, once the encryption key is maliciously intercepted by hackers, etc., it will always Obtain the door-opening password of the transmission between the two, so there are certain security risks. Contents of the invention [0003] In view of the above problems, the present invention proposes a door lock password management system and method, by dynamical...
