Method for accessing to network by device of internet of things, device and system

Abstract

The invention provides a method for accessing to a network by a device of internet of things, a device and a system relating to the field of the internet of things. In adoption of the method, the device and system of the invention, the device of internet of things can securely access to the network, meanwhile, hardware devices provided to the device of internet of things are reduced, and the operation steps of a user are reduced. The method comprises following steps that: the device of internet of things sends an access request message to an access point; the access request message comprises a UUID (Universally Unique Identifier), a SSID (service set identifier) and first pass-tmp; the device of internet of things receives an access response message sent by the access point,; the access response message comprises a SSID and a password; and the device of internet of things accesses to the network by using the SSID and password. The method, the device and the system of the invention are used for accessing to the network by the device of internet of things.

Description

technical field [0001] The present invention relates to the field of Internet of Things, in particular to a method, device and system for Internet of Things devices to access a network. Background technique [0002] The Internet of Things (full name in English: InternetOfThings, English abbreviation: IOT) is the use of communication technologies such as local networks or the Internet to connect sensors, controllers, and household appliances to interact with each other, or to interact with users to form a network of people and things, and things. Connect with things to realize informatization, remote management control and intelligent network. Before the interaction between people and things or between things, IoT devices need to be connected to the network. Therefore, how to make devices easily and safely connect to the network has become a key technology in the field of IoT. [0003] In the prior art, there are mainly the following ways for IoT devices to access the networ...

Problems solved by technology

[0004] 1) The user enters the service set identifier (English full name: servicesetidentifier, English abbreviation: SSID) and password (password) through the Internet of Things device, and the Internet of Things device uses the SSID and password to access the network. In this way, the Internet of Things device needs to be equipped with a touch screen or keyboard. Reduced the cost and volume of IoT devices;

[0005] 2) Users can use smart devices such as mobile phones or computers as access points (English full name: accesspoint, English abbreviation: AP), and inform the IoT device of the SSID and password through the AP. The IoT device uses the SSID and password to access the network. Networked devices have WiFi functions, and user operations are relatively cumbersome and user experience is poor;

[0006] 3) The IoT device uses the broadcast method to request the gateway device to access the network. The gateway device informs the IoT device of the SSID and password, and the IoT device uses the SSID and password to access the network. Although this method is relatively simple to implement, there are security risks and it is easy to be exploited. Others intercept SSID and password;

[0007] 4) Setting up IoT devices through a computer is complex and difficult to deploy on a large scale
