Secured IoT Network via Random ID Tag Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Internet of Things (IoT) networks face security and privacy risks due to the collection and storage of data from multiple sources, leading to potential vulnerabilities and single-point failures in cloud-based systems.
Innovation Solution
The implementation of reconfigurable secure wireless networks using tags with random number IDs, where authorized tag reader apparatuses read and authenticate tag devices to form a secured network by using their unique IDs to retrieve configuration instructions and manage connections between consumer devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cloud-based network infrastructure is used to collect and store data from multiple IoT sources, then data processing capability and network connectivity are improved, but security vulnerabilities and single-point failure risks increase
Solution Approach 1:
The patent segments the centralized cloud network into distributed mesh network nodes, where each node operates independently with unique identifiers. This segmentation eliminates the single-point failure risk of centralized cloud infrastructure while maintaining data processing capabilities across distributed devices.
Solution Approach 2:
Each device in the mesh network is assigned unique local identifiers (MAC address, random number, EUI-64) that enable localized authentication and security validation. This local quality approach allows security verification to occur at the device level rather than relying on centralized cloud validation, improving both security and reliability.
2Productivity
If centralized cloud storage is used for IoT data, then data accessibility and processing efficiency are improved, but privacy risks and security vulnerabilities increase
Solution Approach 1:
The patent implements preliminary authentication using unique device identifiers before any data exchange occurs in the mesh network. This preliminary action establishes security credentials at the device level, enabling private and secure data communication without requiring centralized cloud validation, thus protecting privacy while maintaining accessibility.
3Ease of operation
If traditional network authentication methods are used, then ease of device connection is improved, but network security and authorization control worsen
Solution Approach 1:
The patent implements a universal authentication mechanism using multiple identifier types (MAC address, random number, EUI-64) that can be used across all devices in the mesh network. This universal approach simplifies device connection while maintaining strong authorization control, as any device can be authenticated using its unique identifiers without requiring complex centralized registration.

AI summary
Embodiments described herein are directed to the manufacturing of tag devices, authenticating such devices, authorizing a tag reader apparatus to read tag devices external to the tag reader apparatus, and enabling an authorized tag reader apparatus to form a secured network comprising a plurality of devices, each of which comprise a tag device. The secured network may be formed by simply reading tag devices associated with consumer devices that a user desires to be in the secured network using the authorized tag reader apparatus. The random identification numbers associated with the plurality of consumer devices' tag devices may be used to retrieve instructions that are implemented by the consumer device(s) to form/configure the secured network. The authorized tag reader apparatus is the only device that is enabled to subsequently configure/reconfigure the network and/or the devices included therein, thereby securing the network for use only by the authorized tag reader apparatus.
