Problems solved by technology

[0009] Because in the process of establishing a connection between the smart device and the smart home gateway, the smart device listens to the broadcast in step 101 to obtain the SSID corresponding to the smart home gateway, the smart device determines the available channel in step 102, and the smart device in step 103 The operation of authentication between the device and the smart home gateway through the Wi-Fi connection is time-consuming, which results in a long time from the power-on of the smart device to the successful connection with the smart home gateway

Embodiment 1

[0056] The embodiment of the invention discloses a method for establishing a connection, which is applied to a smart device. The smart device is located in a smart home network, and the smart home network also includes a smart home gateway.

[0057] see figure 2 , figure 2 A flowchart of a method for establishing a connection according to an embodiment of the present invention, including the following steps:

[0058] Step 201, searching for the smart home gateway to be connected on a preset channel according to the preset SSID corresponding to the smart home gateway;

[0059] It should be noted that both the SSID corresponding to the smart home gateway and the channel used by the smart device can be preset. Compared with the prior art, it saves the process of the smart device listening to the SSID and the smart device searching for an available channel.

[0060] Step 202, generate a first shared secret key with the smart home gateway through a preset connection mode;

Embodiment 2

[0080] The embodiment of the invention discloses a method for establishing a connection, which is applied to a smart home gateway. The smart home gateway is located in a smart home network, and the smart home network also includes smart devices.

[0081] see image 3 , image 3 Another flow chart of the method for establishing a connection in the embodiment of the present invention includes the following steps:

[0082] Step 301, generating a second shared secret key with the smart device when a preset condition is met;

[0083] In this step, the preset conditions can be divided into two cases according to the different initiators of the connection between the smart device and the smart home gateway:

[0084] The first case: the initiator is a smart device, and the preset condition can be that the smart home gateway receives the first public key from the smart device through a preset connection method;

[0085] Wherein, the preset connection mode may be RF connection or Blu...

Embodiment 3

[0099] On the basis of the first method embodiment, the embodiment of the present invention describes the specific process of establishing a connection between the smart device and the smart home gateway initiated by the smart device, wherein the application object of the embodiment of the present invention is the smart device.

[0100] see Figure 4 , Figure 4 Another flow chart of the method for establishing a connection according to an embodiment of the present invention includes the following steps:

[0101] Step 401, searching for the smart home gateway to be connected on a preset channel according to the preset SSID corresponding to the smart home gateway;

[0102] Step 402, using a preset key exchange algorithm to generate a first public key of the smart device and a first private key of the smart device;

[0103] In the embodiment of the present invention, the first key exchange algorithm may be the curve25519 algorithm. Since the encryption process using the curve2...

Abstract

The embodiment of the present invention provides a smart device, a smart home gateway, and a method and system for establishing a connection, which are applied to smart devices. The method includes: searching for the smart home gateway on a preset channel according to the wireless subnet name SSID corresponding to the smart home gateway; The preset connection method generates the first shared secret key with the smart home gateway; sends a request message for establishing a passwordless wireless fidelity (Wireless-Fidelity, Wi-Fi) connection to the smart home gateway; receives a message from the smart home gateway Reply to the message, establish a password-free Wi-Fi connection, and the smart device uses the first shared secret key to perform data interaction with the smart home network through the password-free Wi-Fi connection. The application of the embodiment of the present invention can not only realize the connection between the smart device and the smart home gateway, but also ensure the security of the data exchanged between the smart device and the smart home gateway.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a smart device, a smart home gateway, and a method and system for establishing a connection. Background technique [0002] With the rapid development of smart home technology, more and more smart devices can be added to the smart home network through smart home gateways, which greatly facilitates people's work and life. [0003] At present, the specific process of establishing a wireless fidelity (Wireless-Fidelity, Wi-Fi) connection between a smart device and a smart home gateway is as follows: figure 1 Shown: [0004] Step 101, the smart home gateway periodically broadcasts the wireless subnet name (ServiceSet Identifier, SSID) corresponding to the smart home gateway, and the smart device obtains the SSID corresponding to the smart home gateway to be connected by listening to the broadcast from the smart home gateway; [0005] Step 102, the smart device determines the ...
