Embodiment 1

[0045] The following describes a method for establishing a connection provided by the embodiment of this application. The method for establishing a connection is applied to the client. Please refer to figure 1 , the method for establishing a connection in the embodiment of the present application includes:

[0046] In step 101, a device password and a device ID associated with the client are obtained;

[0047] In the embodiment of the present application, each smart home device is configured with a corresponding client when it leaves the factory, which enables each smart home device to perform data interaction with a preset server, and helps users better manage each smart home device. Optionally, after the above-mentioned smart home device is installed, the client of the above-mentioned smart home device can be activated on the Internet to generate a device password and a device ID of the client. When the above-mentioned client needs to establish a connection with the above-m...

Embodiment 2

[0062] Another method for establishing a connection provided by the embodiment of this application is described below. The method for establishing a connection is applied to the server. Please refer to figure 2 , the method for establishing a connection in the embodiment of the present application includes:

[0063] In step 201, receive and parse the connection establishment request sent by the client, and obtain the password to be verified, the user name to be verified and the device ID of the above client;

[0064] In the embodiment of the present application, the above server is always in a state of waiting to receive the request sent by the client. When the server receives the connection establishment request sent by the client, it will analyze the connection establishment request to obtain the client's password to be verified, user name to be verified and device ID carried in the connection establishment request.

[0065] In step 202, a device password associated with t...

Embodiment 3

[0101] A client provided by the embodiment of the present application is described below. see Figure 4 , the above client 400 includes:

[0102] A device parameter obtaining unit 401, configured to obtain a device password and a device ID associated with the client;

[0103] The password-to-be-verified generating unit 402 is configured to perform a hash operation on the device password to obtain the password to be verified;

[0104] A user name to be verified generating unit 403, configured to generate a user name to be verified based on the device password and the current time stamp;

[0105] The request sending unit 404 is configured to send a connection establishment request to the server based on the password to be verified, the user name to be verified, and the device ID, so that the server establishes a connection with the client after successfully verifying the connection establishment request.

[0106] Optionally, the above-mentioned device parameter acquisition un...

Abstract

The application discloses a method for establishing a connection, a client and a server. The method for establishing a connection includes the following steps: acquiring a device password and a deviceID associated with a client; hashing the device password to obtain a password to be verified; generating a user name to be verified based on the device password and the current timestamp; and sendinga connection establishment request to a server based on the password to be verified, the user name to be verified and the device ID so that the server can establish a connection with the client afterverifying the connection establishment request. Through the scheme of the application, encrypted transmission of the user name and password during the establishment of a connection is realized, and the security of the connection establishment process is improved.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a method for establishing a connection, a client, a server and a computer-readable storage medium. Background technique [0002] As an instant messaging protocol, MQTT (Message Queuing Telemetry Transport) is an important part of the Internet of Things. This protocol supports all platforms and can connect all networked objects with the outside world. It is usually used as a communication protocol for sensors and actuators. Based on the MQTT protocol, the username and password of the client can be sent through the username (username) field and the password (password) field of the CONNECT message to implement authentication of the MQTT session. However, in the above process, since the user name and password are transmitted in plain text, its security needs to be improved; moreover, the above process is prone to session replay, resulting in the risk of t...
