Solution Overview

Problem

Existing IoT device authentication methods, such as public-key infrastructure (PKI), are costly in terms of computing power and energy consumption, and traditional storage virtualization technologies lack the security and privacy needed for secure data access in enterprise and cloud-based systems.

Innovation Solution

A storage virtualization architecture utilizing a hybrid blockchain network with both private and public blockchain nodes, where files are sliced into data slices, verified, and stored across hybrid nodes before being submitted to a public blockchain for secure and decentralized storage, leveraging the benefits of both public and private blockchain networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If PKI authentication method is used for IoT devices, then data security and privacy are ensured, but computing power and energy consumption increase significantly

Engineering Contradiction:

Improvedata securityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system segments the blockchain network into public and private portions, allowing authentication operations to be performed locally in the private blockchain without requiring full PKI verification across the entire network, thereby reducing energy consumption while maintaining security

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary authentication mechanism where the hybrid blockchain system acts as a mediator between IoT devices and the network, replacing direct PKI verification with blockchain-based consensus mechanisms that reduce computational overhead

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If public blockchain is used for decentralized storage, then openness and trust are achieved, but data privacy and security are compromised

Engineering Contradiction:

Improvedecentralized storageVSAvoiddata privacy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The blockchain is segmented into public and private portions, where the public blockchain provides decentralized storage and the private blockchain ensures data privacy and security, allowing both openness and confidentiality to coexist

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the blockchain system have different properties: the public portion provides openness and decentralization while the private portion provides security and privacy, with each portion optimized for its specific function

Inventive Principle:

Principle #3Local quality

3Productivity

If traditional storage virtualization is used, then storage resources are consolidated, but security and privacy protection for enterprise data are insufficient

Engineering Contradiction:

Improvestorage efficiencyVSAvoiddata security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system combines traditional storage virtualization technology with hybrid blockchain technology to create a composite storage system that maintains the resource consolidation benefits of virtualization while adding the security and privacy protection capabilities of blockchain

Inventive Principle:

Principle #40Composite materials
