IoT UID Provisioning for Brownfield Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices face challenges in managing their lifecycles, including provisioning, security, and trusted transfers across administrative boundaries, with susceptibility to hacking and lack of trusted device authentication.
Innovation Solution
A registry system for IoT devices using IoT Universal Identifiers (IoT UIDs) managed by a central authority, enabling device authentication, trust and risk assessment, and lifecycle management, with features like single-pane-of-glass displays for simplified access and fraud detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional domain controller servers are used to manage security groups, then device authentication can be performed, but system complexity and security vulnerability increase
Solution Approach 1:
The patent extracts the device authentication function from traditional domain controller servers and relocates it to a distributed blockchain-based system. Each device has its own unique identifier stored on the blockchain, eliminating the need for centralized domain controllers while maintaining secure authentication capabilities.
Solution Approach 2:
The blockchain serves as an intermediary between devices for authentication purposes. Instead of devices directly communicating with domain controllers, all authentication transactions are mediated through the blockchain, which provides a decentralized, tamper-proof record of device identities and permissions.
2Reliability
If approved lists are maintained by devices to trust other devices, then security can be enforced, but real-time trust assessment capability is reduced
Solution Approach 1:
The system performs preliminary actions by pre-provisioning unique device identifiers and registering device information on the blockchain before devices need to interact. This includes pre-establishing device profiles, permissions, and trust parameters on the blockchain, so that when devices need to authenticate, the information is already available for immediate verification.
Solution Approach 2:
The blockchain provides continuous feedback about device status, permissions, and trust levels to any querying device. When a device needs to verify another device's trustworthiness, the blockchain instantly returns the current state of the target device's identifier and associated metadata, enabling real-time trust assessment without manual list updates.
3Adaptability or versatility
If centralized registries are used to track device histories, then comprehensive device management is achieved, but system vulnerability to attacks increases
Solution Approach 1:
The patent extracts the centralized device registry function and distributes it across the blockchain network. Device lifecycle information including histories, permissions, and trust indicators are stored as immutable records on the blockchain, eliminating single points of failure and reducing vulnerability to centralized attacks.
Solution Approach 2:
The system uses composite security architecture combining blockchain's distributed ledger technology with device-level unique identifiers and cryptographic verification. This composite approach integrates multiple security layers: decentralized storage, cryptographic hashing, and device-specific credentials, creating a more resilient system against attacks.

AI summary
A method including: interpreting, via a device registration request circuit, a registration request that maps device property data to one or more Brownfield devices; generating, via an Internet of Things Universal Identification (IoT UID) generation circuit, based at least in part on the registration request, an IoT UID for each of the one or more Brownfield devices; and transmitting, via an IoT UID provisioning circuit, the IoT UID for each of the one or more Brownfield devices.
