Solution Overview

Problem

Current encryption methods, such as Public Key Infrastructure (PKI), are vulnerable to reverse engineering due to publicly stored key-pairs, and QR codes used in large-scale transactions are susceptible to data compromise when outside internal controls, necessitating enhanced security measures.

Innovation Solution

Transactional Cryptography employs multiple layers of encryption and Discreet Key Exchange methodology to generate unique, one-time asymmetrical key-pairs for each communication transaction, not publicly stored, using a trusted third-party to manage key distribution and ensure secure data transmission within QR codes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Public Key Infrastructure (PKI) is used for encryption, then data transmission security is improved, but vulnerability to reverse engineering increases due to publicly stored key-pairs

Engineering Contradiction:
Improvedata transmission securityVSAvoidreverse engineering vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful element of public key storage by removing the public key from public repositories. Instead, public keys are distributed through a controlled key distribution server that provides them only to authorized recipients for specific transactions, eliminating the vulnerability of publicly exposed keys while maintaining secure communication.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a key distribution server as an intermediary between key pairs and users. This mediator controls key distribution, providing public keys only to authorized recipients through authenticated requests, thereby preventing unauthorized access and reverse engineering while enabling secure communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If QR codes are used for large-scale transactions, then transaction efficiency is improved, but data compromise risk increases when outside internal controls

Engineering Contradiction:
Improvetransaction efficiencyVSAvoiddata security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-generating and storing public keys in a secure key distribution server before transactions occur. When QR code transactions happen outside internal controls, the system has already prepared the necessary cryptographic materials, enabling secure communication without real-time key generation or exchange negotiations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses a key distribution server as an intermediary that provides public keys to QR code scanning applications. This mediator enables QR codes to function securely in uncontrolled environments by supplying the necessary cryptographic infrastructure through a trusted third-party service.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple layers of encryption with one-time key-pairs are used, then communication security is improved, but system complexity increases

Engineering Contradiction:
Improvecommunication securityVSAvoidencryption system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling automated key pair generation, distribution, and management through software applications. The system automatically handles the complexity of multiple encryption layers and one-time key-pairs without requiring user intervention, making the complex security protocol as easy to use as standard QR code scanning.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent creates a universal key distribution server that serves multiple functions: generating key-pairs, distributing public keys, verifying transactions, and managing security protocols. This multi-functional approach consolidates complex security operations into a single accessible service that can be integrated into various applications including QR code scanners and cryptographic systems.

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