Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If classical encryption schemes (e.g., RSA 2048) are used for data protection, then current security requirements are met, but security is compromised against quantum computer attacks

Engineering Contradiction:
Improvesecurity against quantum attacksVSAvoidvulnerability to quantum decryption
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the cryptographic parameters from classical algorithms (RSA, ECC) to post-quantum algorithms (lattice-based, hash-based, code-based cryptography). This parameter change enables resistance against quantum attacks while maintaining compatibility with existing infrastructure, directly resolving the security vulnerability to quantum decryption

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements post-quantum cryptography in advance, before quantum computers become practically capable of breaking classical encryption. This preliminary action prepares the system proactively against future quantum threats, preventing security compromises before they can occur

Inventive Principle:
Principle #10Preliminary action

2Reliability

If post-quantum cryptography is implemented, then quantum resistance is achieved, but computational overhead and key sizes increase

Engineering Contradiction:
Improvequantum resistanceVSAvoidcomputational overhead
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies different post-quantum cryptographic schemes to different security requirements and data types. By selecting appropriate algorithms (e.g., CRYSTALS-Kyber for key encapsulation, CRYSTALS-Dilithium for signatures) based on specific security needs, the system achieves quantum resistance while optimizing computational overhead for each application context

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent enables dynamic selection and adjustment of cryptographic parameters and algorithms based on security requirements, performance constraints, and threat models. This dynamic approach allows the system to balance quantum resistance with computational efficiency, adapting to different operational conditions

Inventive Principle:
Principle #15Dynamics

3Reliability

If quantum computers are awaited for PQC deployment, then optimal quantum-resistant security is achieved, but implementation timeline is extended indefinitely

Engineering Contradiction:
Improveoptimal quantum-resistant securityVSAvoiddeployment delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements post-quantum cryptography now, on classical computers, rather than waiting for quantum computers to mature. This preliminary deployment captures security benefits immediately while the technology is being standardized, avoiding indefinite delays and providing proactive protection against future quantum threats

Inventive Principle:
Principle #10Preliminary action

4Reliability

If higher security levels (e.g., 256-bit) are applied to all data, then maximum security is achieved, but processing speed and efficiency decrease

Engineering Contradiction:
Improvedata security levelVSAvoidprocessing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies different security levels and cryptographic strengths to different data types and security requirements rather than uniformly applying maximum security to all data. This selective approach maintains high security for sensitive information while improving processing speed for less critical data, optimizing the balance between security and productivity

Inventive Principle:
Principle #3Local quality
