Problems solved by technology

[0004] Chinese Patent Document No. CN103763757A Publication (Announcement) Day 2014.04.30 discloses a fast networking method based on the embedded Wi-Fi module of the Internet of Things, but this method has potential safety hazards: hackers use any Wi-Fi device to monitor, The configuration information transmitted unencrypted can be intercepted
In today's emphasis on network security, this method cannot meet the basic personal information security requirements of users
CN103841626A publication (announcement) date 2014.06.04 discloses a wireless terminal of the Internet of Things and its configuration method and mobile terminal. This technology uses a similar scheme of broadcast packets, which also does not solve the security problem
However, the disadvantages of the traditional configuration method are: users need to use a mobile terminal to log in to each Wi‐Fi IoT device for configuration
However, this technology does not consider the security of wireless transmission, that is, it does not consider how to transmit sensitive configuration information to the IoT controller
In addition, in this technology, an IoT controller only uses the AP mode for direct connection control of user terminals, without considering the connection with other IoT controllers

Embodiment 1

[0024] Such as figure 1 As shown, in this embodiment, the wireless router R is connected to the Internet, and a mobile terminal (such as a smart phone) P can connect to the wireless router R. There are a large number of Wi‐Fi IoT devices w0, w1, w2, ... that need to be installed and initially configured to connect to the wireless router R and connect to the IoT server S in the cloud.

[0025] In this embodiment, one of the Wi-Fi IoT devices w0 is configured in a secure manner, and w0 is selected as the master device, and then the master device w0 configures other Wi-Fi IoT devices w1, w2, ... in a secure manner ,So on and so forth.

[0026] The Wi-Fi Internet of Things device uses two different MAC addresses and supports two Wi-Fi functions at the same time: Wi-Fi Soft-AP function (that is, a Wi-Fi access point with limited functions) and Wi-Fi Fi STA functionality (i.e. a standard Wi‐Fi device). Using these two features works differently at different times.

[0027] a), s...

Embodiment 2

[0041] This embodiment requires Wi-Fi IoT devices to support two Wi-Fi functions: Wi-Fi Soft-AP function (that is, a Wi-Fi access point with limited functions) and Wi-Fi STA function (that is, a standard Wi‐Fi equipment). Use these two functions separately at different times.

[0042] a), specifically, before the initial configuration is completed, when in the waiting configuration mode, the Wi-Fi Internet of Things device uses the Wi-Fi Soft-AP function to allow a smartphone or a Wi-Fi Internet of Things device that is already in working mode to access ;

[0043] b), specifically, after the initial configuration is completed, when it is in the working mode, the Wi-Fi IoT device uses the Wi-Fi STA function to connect to a specific wireless router R, which is the Wi-Fi access point, so as to access the Internet, Connect to the IoT server S in the cloud; at the same time, use another Wi‐Fi STA function to find a Wi‐Fi IoT device in configuration mode connected to the same grou...

Abstract

The invention discloses an implementation method of safe batch configuration of a Wi-Fi Internet of Things system, a master device in the Wi-Fi Internet of Things is configured through a safe manner, and then authentication and configuration are carried out on other devices in the Wi-Fi Internet of Things by the master device through a point-to-multipoint manner; the master device utilizes two different MAC (Media Access Control) addresses and synchronously supports two working modes including Wi-Fi Soft-AP and Wi-Fi STA; a mobile terminal of a user carries out initial configuration on the master device of the Wi-Fi Internet of Things in the Wi-Fi Soft-AP mode; and the master device is connected to other devices in the same group through the other Wi-Fi function to help other devices to complete agent initial configuration. According to the implementation method, a large amount of Wi-Fi Internet of Things devices are completed through a form of exponential growth, privacy data security is guaranteed and a large amount of manual cost can be saved.

Description

technical field [0001] The present invention relates to a method in the technical field of the Internet of Things, in particular to a method for implementing a secure batch configuration of a Wi-Fi Internet of Things system. Background technique [0002] Internet of Things (IOT, Internet Of Things) devices may be various information sensors and controllers, or various intelligent household appliances. A huge network formed by Internet of Things devices connected to the Internet has realized the extension of the Internet from people to things and triggered a new technological innovation. Among them, Wi-Fi IoT devices, that is, IoT devices use Wi-Fi technology to access the Internet, which has the lowest access cost and the best scalability. For example, household appliances, lights, and various sensors can be connected to the cloud by connecting to the Internet through a home Wi-Fi access point (Wi-Fi Access Point is also called a Wi-Fi hotspot or wireless router) as Wi-Fi I...
