System and method for managing password authority to smart door lock

Abstract

The present invention discloses a system and method for managing a password authority to a smart door lock. As long as a user binds a door lock APP with a door lock and performs time synchronization, a temporary door opening password can be remotely and dynamically generated and shared to a visitor. Because the door lock APP and the door lock adopt the same custom password generation algorithm, a temporary door opening password is calculated by taking a delivery serial number of the door lock, a secret key value set by a user and unlocking allowance time set by the user as parameters, and the user can allow other people to open the door lock by means of the temporary door opening password without needing to share a password used for a long time customarily. Moreover, the temporary door opening password generated herein does not need to obtain generation elements of a secret key from a cloud terminal, so it is unnecessary to connect the door lock to the internet, it may be unnecessary to remotely set a new password by means of the background of the internet, and therefore much privacy is provided for domestic/personal users. Hardware is not highly required, the cost is low, the implementation is simple, and the user experience is excellent.

Description

technical field [0001] The invention relates to a password authority management system and method of an intelligent door lock. Background technique [0002] The smart door locks used in the market now have a variety of opening methods, such as Bluetooth unlocking, NFC unlocking, keyboard password unlocking, etc. The essence is that the user enters the password in a certain way to unlock. For current smart door locks, when there is no access to the Internet, users can use mobile APPs to set long-term valid passwords for the door locks through near-field communication technologies such as Bluetooth. If the owner of the household who uses the smart door lock is out of the local area, if someone needs to unlock and enter the house with the permission of the householder, for the smart door lock that is not connected to the Internet, the user cannot remotely set a temporary password into the door lock. For security reasons, I don't want to share my long-term use password with oth...

AI Technical Summary

Problems solved by technology

If the owner of the household who uses the smart door lock is out of the local area, if someone needs to unlock and enter the house with the permission of the householder, for the smart door lock that is not connected to the Internet, the user cannot remotely set a temporary password into the door lock. For security reasons, I don’t want to share my long-term use password with others. This situation makes it impossible for others to unlock and enter the room

If the user shares the long-term password with others as a last resort, since the password has no timeliness and number of times, there is a great security risk

Of course, the above problems can also be solved by using a password matching algorithm. As long as the password conforms to the matching algorithm, it can be used to unlock the lock. Such a password does not fundamentally solve the problem that the password has no timeliness and number of times. Comply with the matching algorithm) to unlock, not only has no timeliness, but also has poor security

Connecting the smart door lock to the Internet, users can use the mobile phone APP to set a temporary dynamic password for the door lock through the cloud server, which can solve the above problems, but it will cause high hardware costs, high power consumption, and complicated public network communication management. It also means that all door lock information is managed in the background of the network, lacking communication security, complex implementation, and not practical
