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 secure communication method based on an intelligent door lock system and belongs to the technical field of intelligent home and security. The intelligent door lock system comprises an intelligent door lock and a mobile terminal which are in remote communication connection with a cloud server respectively. The method comprises the steps that the intelligent door lock and the mobile terminal are connected through a preset secure communication channel, and encryption keys are exchanged; to-be-transmitted data is generated through a sending end and encrypted through the encryption keys by using a preset encryption algorithm, and encrypted data is obtained; the sending end sends the encrypted data with the unique identification to a receiving end through the cloud server; identity authentication is conducted through the receiving end on the encrypted data with the unique identification, and the encrypted data is processed according to an identity authentication result. According to the method, no encryption key is saved in the server so that the server cannot understand the data forwarded through the server, even if the server is compromised, data encryption, identity authentication and replacement and tamper resisting in the communication between the intelligent door lock and the mobile terminal are still effective, and data security is ensured.

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...
