Problems solved by technology

However, in the existing smart door lock system, the server often needs multiple handshakes in the process of issuing keys, such as figure 1 As shown, in order for the smart door lock to better obtain confirmation information, at least three handshakes are required between the cloud server and the smart door lock to complete the issuance of the key, thereby establishing a communication channel, especially when there are multiple smart door locks, This will increase the communication pressure of the two, reduce the communication efficiency, etc.

Embodiment 1

[0038] Please refer to figure 2 , this embodiment proposes a smart door lock key update method, which can be applied to key distribution and update of smart door locks and cloud servers. Through this method, the number of communication handshakes between the smart door lock and the cloud server can be reduced while ensuring the normal delivery of the key, thereby improving communication efficiency and the like. The method for updating the key of the smart door lock is described below.

[0039] Step S10, the cloud server sends a key update command to the smart door lock. The key update command includes the new key encrypted with the old key. In this embodiment, the old key is the pre-agreed default key or the key used by the smart door lock when it was updated last time.

[0040] In the above step S10, when the cloud server issues a new key, it will be encrypted with the pre-agreed default key, or it will be encrypted with the key used by the smart door lock when it was upd...

Embodiment 2

[0058] Please refer to Figure 5 , this embodiment proposes a smart door lock key update system 1, which can adopt the smart door lock key update method in the above-mentioned embodiment 1. The smart door lock key update system 1 includes a cloud server 10 and at least one smart door lock 20 , and the cloud server 10 is connected to the smart door lock 20 in communication.

[0059] Exemplarily, the smart door lock 20 is used to receive a key update command from the cloud server 10, the key update command includes a new key encrypted with an old key, and the old key is a pre-agreed The default key or the key the smart door lock 20 was using when it was last updated.

[0060] The smart door lock 20 is also used to obtain and store the new key and back up the old key, and send a test request encrypted with the new key to the cloud server 10 .

[0061] The cloud server 10 is configured to receive the test request and use the new key to decrypt the test request.

Abstract

The invention discloses an intelligent door lock secret key updating method and system and a computer storage medium. The method comprises the steps that a secret key updating command issued by a cloud server is received, the secret key updating command comprises a new secret key encrypted through an old secret key, and the old secret key is a default secret key agreed in advance or a secret key used by an intelligent door lock in the last updating process; and a new key is acquired and stored, an old key is backed up and a test request encrypted by using the new key is sent to the cloud server, so that the cloud server successfully decrypts the test request and then starts the new key. According to the technical scheme provided by the invention, the handshake times of the intelligent doorlock and the cloud server can be reduced by using a double-key mode, a communication handshake mechanism between the intelligent door lock and the cloud server is optimized, and the communication efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent door locks, in particular to an intelligent door lock key updating method, system and computer storage medium. Background technique [0002] In the current smart door lock system, door locks from different companies have their own interactive communication methods, including smart door locks that have interactive communication with the platform. Interacting with the platform can increase the flexibility of the door lock. For example, the online door opening password can be issued through the platform to realize remote door opening and other operations; you can also check the online status of the door lock through the platform at any time. [0003] Considering the security of these interactive data such as the door opening password, the platform usually needs to perform data encryption processing when sending data to the door lock; correspondingly, after the smart door lock obtains the ...
