Problems solved by technology

However, after the server is compromised, the normal communication between the server and both ends can be simulated, and the identity verification of the server cannot be intercepted.
[0007] At present, there is no realization in the market that can ensure that the server or internal personnel cannot obtain the user's transmission information from the server, or even if the server is compromised, the identity verification, anti-replay, and anti-tampering in the communication between the door lock and the mobile phone client Secure smart door lock-based communication method that still works

Embodiment 1

[0134] A safety communication method based on an intelligent door lock system, comprising the steps of:

[0135] (1) In response to the user's authorized operation instruction, the smart door lock and the mobile terminal respectively open a secure communication channel, and the secure communication channel is a communication channel triggered by the authorization of the smart door lock and the mobile terminal;

[0136] The smart door lock or terminal generates an initial encryption key for authentication to obtain the encryption key; the initial encryption key is a key automatically generated or manually input by the smart door lock or mobile terminal.

[0137] Specifically, the user's authorized operation instruction can be, for example, that the user manually presses the configuration button or configuration mode touch key, or enters the set administrator password locally on the smart door lock or enters the fingerprint of the administrator authority, etc. (equivalent to the ...

Embodiment 2

[0147] A safety communication method based on an intelligent door lock system, comprising the steps of:

[0148] (1) In response to the user's authorized operation instruction, the smart door lock and the mobile terminal respectively open a secure communication channel, and the secure communication channel is a communication channel triggered by the authorization of the smart door lock and the mobile terminal;

[0149] The smart door lock or terminal generates an initial encryption key for authentication to obtain the encryption key; the initial encryption key is a key automatically generated or manually input by the smart door lock or mobile terminal.

[0150] Specifically, the user's authorized operation instruction can be, for example, that the user manually presses the configuration button or configuration mode touch key, or enters the set administrator password locally on the smart door lock or enters the fingerprint of the administrator authority, etc. (equivalent to the sm...

Abstract

The invention discloses a safe communication method based on an intelligent door lock system, which belongs to the technical field of intelligent home and security protection. The smart door lock system includes a smart door lock, and a mobile terminal is remotely connected to a cloud server. The method includes: connecting the smart door lock and the mobile terminal through a preset secure communication channel and exchanging encryption keys; The data is transmitted and encrypted with the encryption key using a preset encryption algorithm to obtain encrypted data; the sender sends the encrypted data with a unique identifier to the receiver through the cloud server; the receiver authenticates the encrypted data with a unique identifier , to process encrypted data based on authentication results. In the method of this application, since the server does not save any keys, the server cannot understand the data forwarded by it. Even if the server is compromised, the data encryption, identity verification, anti-replay and anti-tampering in the communication between the smart door lock and the mobile terminal are still valid , ensuring data security.

Description

technical field [0001] The invention relates to a secure communication method based on an intelligent door lock system, which belongs to the technical field of intelligent home and security protection. Background technique [0002] Most of the smart door locks in the existing market have networking functions; the information of smart door locks can be reported to the server, and then forwarded to the app used by the user; users can also remotely issue passwords and set permissions through the server. As smart door locks get installed more, the security of remote communication becomes more important. As the core of forwarding, the server is at great risk of being attacked. This will lead to serious accidents such as the door lock being attacked and the password leaked or opened. [0003] For this problem, the existing solutions include the following methods: [0004] (1) The remote unlock function is prohibited. However, smart door locks can generally issue passwords, Blu...
