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] like figure 1 As shown, in this embodiment, the wireless router R is connected to the Internet, and the mobile terminal (eg, a smart phone) P can be connected 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 the wireless router R to the IoT server S in the cloud.

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

[0026] The described Wi-Fi IoT device uses two different MAC addresses and supports two Wi-Fi functions simultaneously: Wi-FiSoft-AP function (i.e. behaves as a limited Wi-Fi access point) and Wi-FiSoft-AP function Fi STA function (ie a standard Wi-Fi device). At different times, using these two functions has different effects.

[0027] a), specifically: before the init...

Embodiment 2

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

[0042] a), specifically, before the initial configuration is completed, when in the to-be-configured mode, the Wi-Fi IoT device uses the Wi-FiSoft-AP function to allow access to a smartphone or a Wi-Fi IoT device that is already in working mode;

[0043] b) Specifically, after the initial configuration is completed, when in the working mode, the Wi-Fi IoT device uses the Wi-Fi STA function to connect to a specific wireless router R, that 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 the Wi-Fi IoT device in configuration mode connected to the same group, and comp...

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 invention relates to a method in the technical field of the Internet of Things, in particular to a method for realizing a secure batch configuration of a Wi-Fi Internet of Things system. Background technique [0002] Internet of Things (IOT, Internet Of Things) devices can be various information sensors and controllers, and can also be various intelligent household appliances. A huge network formed by the Internet of Things devices connecting to the Internet realizes the extension of the Internet from people to things and triggers 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 as Wi-Fi IoT devices connected to the Internet through a home Wi-Fi access point (Wi-Fi Access Point, also known as Wi-Fi hotspot or wireless r...
