Entrance guard authentication method and system, client, server and door lock device

Abstract

The invention relates to an entrance guard authentication method. The method comprises the following steps of obtaining the attribute information corresponding to an offline temporary password configured by a user and the user parameters corresponding to the user; encrypting the attribute information and the user parameters according to an FPE algorithm to generate an offline temporary password; verifying an offline temporary password inputted on an entrance guard system according to the attribute information; after verification succeeds, outputting an unlocking instruction, and controlling the entrance guard system to execute an unlocking action; generating the unlocking information of the entrance guard system according to the unlocking instruction; and performing AES encryption on the unlocking information according to the offline temporary password to obtain and store the unlocking encryption information. According to the technical scheme, the password on the door lock can be remotely managed, and the temporary password can be normally used even in an area with a poor network.

Description

technical field [0001] The invention relates to the technical field of access control authentication, in particular to an access control authentication method and system, a client, a server, and a door lock device. Background technique [0002] Now the way to realize the temporary password of the wifi door lock is: when the user enters the password on the door lock, the door lock connects the wifi module to the network, and the password data is pulled from the cloud through the wifi module and stored locally in the door lock. Then the door lock will verify the pulled password and the input password. If the verification is passed, the door lock will open the door. [0003] Based on the current actual wireless network technology, the short-distance ble is limited by the connection distance, so it cannot guarantee that the operator can remotely manage the password on the lock. Remote communication such as wifi cannot guarantee 100% network reliability, especially in areas with...

AI Technical Summary

Problems solved by technology

[0003] Based on the current actual wireless network technology, due to the limited connection distance of short-distance ble, it is impossible to guarantee that the operator can remotely manage the password on the lock

Remote communication such as wifi cannot guarantee 100% network reliability, especially in areas with poor overseas network infrastructure, the user experience is not good

Online temporary passwords need to synchronize data with the server at regular intervals, which increases power consumption and shortens battery life
