Configurator Device Automates IoT Network Credential Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require manual configuration to connect to wireless networks, which is time-consuming and inefficient, especially in scenarios involving large numbers of unconfigured IoT devices.
Innovation Solution
A configurator device service that obtains network credentials from a centralized credential provisioning service and broadcasts a configurator identifier, allowing unconfigured devices to connect to the wireless network by authenticating and obtaining necessary credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration is used for each device to connect to wireless networks, then network security and control are maintained, but the configuration process becomes time-consuming and inefficient
Solution Approach 1:
A configurator device is introduced as an intermediary between the wireless network and unconfigured devices. The configurator device obtains network credentials from a credential provisioning service and transmits them to unconfigured devices, automating the configuration process while maintaining security through controlled credential distribution
Solution Approach 2:
Unconfigured devices automatically discover and connect to the configurator device, receive credentials without manual intervention, and independently complete their network configuration. This self-service mechanism eliminates the need for manual configuration while maintaining security through automated credential verification
2Ease of operation
If automated credential distribution is implemented, then configuration efficiency is improved, but network security requirements become more complex
Solution Approach 1:
The configurator service combines multiple functions into a single device: it acts as a credential server, authentication intermediary, and configuration manager. This consolidation simplifies the overall system architecture while maintaining security through integrated credential verification and controlled distribution
3Extent of automation
If a centralized credential provisioning service is used, then credential management is streamlined, but system architecture complexity increases
Solution Approach 1:
The configurator device serves as an intermediary layer between the centralized credential provisioning service and individual unconfigured devices. This intermediary approach enables automated credential distribution without requiring direct complex interactions between the provisioning service and each device, simplifying the overall system architecture

AI summary
A technology is described for connecting an unconfigured device to a wireless network using network credentials obtained via a configurator device. An example of the technology may include activating a configurator service on a device to allow the device to act as a configurator device and provide network credentials of a wireless network to unconfigured devices. The configurator device may receive a connection request from an unconfigured device to obtain the network credentials to enable the unconfigured device to connect to the wireless network. The configurator device may determine that the unconfigured device is authorized to connect to the wireless network, obtain the network credentials from a credential provisioning service, and send the network credentials to the unconfigured device to enable the unconfigured device to connect to the wireless network.
