Solution Overview

Problem

Device authentication in the Internet of Things (IoT) leads to increased network resource overhead and potential information leakage.

Innovation Solution

Implementing a device authentication method using the Transport Layer Security (TLS) protocol for secure connections between electronic devices and servers, utilizing digital certificates (X.509 format) and vendor identifiers (VIDs) to authenticate devices, and generating unique keys for each device to ensure authenticity and reduce network resource demand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional device authentication methods are used in IoT, then device security and authenticity can be verified, but network resource overhead increases and information leakage risks arise

Engineering Contradiction:
Improvedevice authentication securityVSAvoidnetwork resource overhead
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts and separates the authentication data from the device itself, storing it externally on a server. The device only retains minimal identification information, while the server holds the comprehensive authentication data including digital certificates and vendor identifiers. This extraction reduces the computational and storage burden on resource-constrained IoT devices while maintaining security.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a server as an intermediary between devices and the authentication system. The server acts as a mediator that stores authentication data, processes verification requests, and returns results to devices. This intermediary approach centralizes the heavy authentication operations, allowing devices to participate in authentication with minimal resource consumption.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If comprehensive authentication data is stored on devices, then authentication reliability is improved, but device storage requirements and security risks increase

Engineering Contradiction:
Improveauthentication verificationVSAvoiddevice storage and security management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the burden of storing comprehensive authentication data from the device by extracting it and storing it on the server instead. The device only keeps essential identification information, while the server stores the complete authentication package including digital certificates, vendor identifiers, and device metadata.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The server is designed to serve multiple functions: storing authentication data for multiple devices, processing authentication requests, managing device registries, and providing verification services. This universal approach allows the system to handle authentication for numerous devices without increasing individual device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
