IoT Hub Automatic Wireless Network Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in automatically connecting new IoT devices to WiFi networks, especially when out of range or with multiple networks, leading to registration failures and requiring manual configuration, which complicates the process for OEMs to deliver pre-connected devices.
Innovation Solution
An IoT platform with a hub system that uses a predefined networking protocol stack, secure key exchange techniques, and barcode/QR code pairing for automatic wireless network authentication, allowing devices to connect seamlessly to existing networks without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual WiFi configuration is used for IoT device registration, then network connection can be established, but user operation complexity increases and setup time is extended
Solution Approach 1:
The patent pre-provisions IoT devices with unique identifiers, cryptographic keys, and network credentials during manufacturing. This preliminary configuration enables devices to automatically authenticate and connect to WiFi networks without requiring manual user input, thereby maintaining connection reliability while dramatically simplifying the setup process for users.
2Loss of time
If device registration is performed outside home WiFi coverage area, then device can be activated earlier, but registration fails due to low coverage conditions
Solution Approach 1:
The patent introduces a cloud-based authentication server as an intermediary that receives device registration requests from anywhere in the world. Instead of requiring direct WiFi connection between the device and home network during provisioning, the cloud server mediates the authentication process using pre-provisioned credentials, enabling successful registration outside home coverage area while maintaining high reliability.
3Area of stationary object
If multiple WiFi networks exist in home or business, then network coverage is extended, but device registration becomes more complicated requiring separate processes for each network
Solution Approach 1:
The patent implements a universal cloud-based authentication system that can register devices for multiple WiFi networks through a single unified process. The pre-provisioned device credentials work across any number of networks, and the cloud server handles authentication for multiple networks simultaneously, eliminating the need for separate registration processes for each network while maintaining extended coverage capabilities.
4Reliability
If OEMs send devices without pre-configuration, then device security is maintained, but users cannot connect devices to networks without being inside the hosted location
Solution Approach 1:
The patent resolves this contradiction by performing preliminary security provisioning during manufacturing - devices are pre-configured with unique identifiers, cryptographic keys, and network credentials in a secure factory environment. This maintains device security while enabling users to connect devices to networks anywhere in the world without needing to be physically present at the network location, as the pre-provisioned credentials enable automatic authentication.
Data Source
AI summary
A system, apparatus, and method are described for a secure IoT wireless network configuration. For example, one embodiment of an Internet of Things (IoT) hub comprises: a local wireless communication interface to establish local wireless connections with one or more IoT devices and/or IoT extender hubs; a network router to establish network connections over the Internet on behalf of the IoT devices and/or IoT extender hubs; an authentication module pre-configured with a passphrase and a hidden service set identifier (SSID), the authentication module to receive a connection requests from the IoT devices and/or an IoT extender hubs and to grant the connection requests when the IoT devices and/or IoT extender hubs use the pre-configured passphrase and hidden SSID; and a firewall of the IoT hub to block all outgoing and incoming connection requests other than those directed to designated servers of an IoT service with known host names.
