A method and system for access authentication of an internet of things gateway

Abstract

The present invention provides an Internet of Things gateway access authentication method and system; the method includes: S110, after the Internet of Things device is turned on, scans the wireless channel of the corresponding access mode according to its own wireless access mode, and selects a wireless channel that meets the predetermined condition, According to predetermined rules, generate a dedicated access password for the Internet of Things to access the selected wireless channel, connect to the Internet of Things gateway, and upload device description information; S120. After the Internet of Things gateway detects that an Internet of Things device is connected, block the Internet of Things device from sending The communication of other devices or networks is authenticated according to the device description information uploaded by the IoT device. If the authentication is successful, the IoT device is allowed to access, and the data communication between the IoT device and other devices or networks is opened. The invention can facilitate the realization of plug-and-play access authentication of the Internet of things equipment.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and system for access authentication of an Internet of Things gateway. Background technique [0002] With the rapid development of the Internet of Things, there may be a large number of Internet of Things devices in users' homes in the future. In order to improve the user experience, on the one hand, these IoT devices need to be easily connected to the IoT gateway to achieve plug-and-play; Therefore, it is necessary to perform access authentication for IoT devices. [0003] At present, the research on plug-and-play of IoT devices is relatively weak. The plug-and-play of IoT devices is mainly based on a framework similar to UPnP (Universal Plug and Play) protocol; Access to the wireless channel provided by the IoT gateway, and then realize the access authentication and discovery of the IoT device through the process of service discovery and service request and resp...

AI Technical Summary

Problems solved by technology

[0004] There are two main types of problems in realizing the access of IoT devices based on the plug-and-play technology similar to the UPnP framework: 1) Before accessing, the user needs to configure the wireless channel for the IoT device in advance, and manually set the authentication information for wireless access. There is a threshold for users to access the wireless channel provided by the IoT gateway through wireless access authentication; but if the authentication information is not set, the security will be reduced; 2) UPnP protocol is a peer-to-peer structure protocol, Its protocol and accompanying authentication process are too complex for sensor-type IoT devices with weak computing and storage capabilities
