IoT Network Management via Secure Auto-Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for managing parent-child devices in an IoT environment, such as electric vehicle charging stations, face challenges in efficiently configuring and connecting multiple child devices to a parent device, as each child device needs to be individually configured to connect to a specific Wi-Fi network, making the process tedious and prone to security vulnerabilities.
Innovation Solution
A network management system that includes a parent device with a default Wi-Fi SSID configuration, a network configuration module that locks the network, generates a new secure configuration, and transmits it to child devices, which then confirm receipt before disabling the default configuration, ensuring secure and automated connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each child device is individually configured to connect to a specific parent device, then connection specificity is improved, but configuration complexity and time consumption increase
Solution Approach 1:
The system enables self-service configuration where child devices automatically discover and connect to parent devices using pre-configured matching rules (e.g., device IDs, codes). The configuration module on each device handles the connection establishment autonomously without requiring manual individual configuration, thus reducing configuration time while maintaining connection specificity.
Solution Approach 2:
The patent applies preliminary action by pre-configuring devices with identification information and matching rules before deployment. When devices come into proximity, they can immediately establish connections based on pre-established criteria, eliminating the need for time-consuming individual configuration during deployment.
2Ease of operation
If default Wi-Fi configuration is continuously available, then ease of connection is improved, but network security deteriorates
Solution Approach 1:
The system implements periodic action by temporarily enabling the default Wi-Fi configuration only during the connection establishment phase, then automatically disabling it after a predetermined time period or upon successful connection. This ensures that the default configuration is available when needed for connection but not continuously exposed to security risks.
Solution Approach 2:
The patent applies beforehand cushioning by implementing security measures prior to potential unauthorized access. The system automatically disables the default configuration after use and requires re-authentication for subsequent connections, preventing unauthorized devices from exploiting continuously available default credentials.
3Manufacturing precision
If manual configuration process is used for each child device, then configuration precision is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary configuration module that automates the configuration process. This module handles device discovery, matching, and connection establishment based on pre-configured rules, maintaining configuration accuracy while eliminating the need for complex manual configuration procedures for each device.
Solution Approach 2:
The patent applies copying by using template-based configuration where a standard configuration pattern is replicated across multiple devices. Instead of manually configuring each device individually, the system copies and applies pre-defined configuration templates, ensuring consistency and accuracy while reducing complexity.

AI summary
A network management system in an Internet-of-Things (IoT) environment includes a parent device with a first default configuration including a service set identifier (Wi-Fi SSID) that uniquely identifies a Wi-Fi network, a child device, wherein the child device is configured to identify the Wi-Fi SSID of the parent device, a network, wherein the parent device and the child device are configured to communicate via the network, and a network configuration module that is configured via computer executable instructions to lock the network, generate a second default configuration, provide the second default configuration to each child device, and turn off the second default configuration after the child device confirmed receipt of the second default configuration.
