Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudo-random number generation is used for session key generation, then the system is easy to implement and computationally efficient, but the generated keys become vulnerable to brute force attacks and key reproduction
Solution Approach 1:
The patent replaces traditional computational pseudo-random number generation with quantum mechanical processes. Specifically, it uses quantum random number generation (QRNG) based on quantum phenomena such as photon polarization or vacuum fluctuations to produce truly random numbers, thereby eliminating the predictability and reproducibility issues of classical pseudo-random generators while enhancing session key security
Solution Approach 2:
The patent fundamentally changes the nature of randomness from pseudo-random (deterministic but unpredictable) to truly random (indeterministic) by utilizing quantum mechanical parameters. This involves measuring quantum states such as photon polarization angles or quantum vacuum fluctuations, which inherently produce unpredictable outcomes that cannot be reproduced even with complete knowledge of initial conditions
2Use of energy by moving object
If traditional pseudo-random number generation is used, then computing resources are efficiently utilized, but the increasing computing power of attackers enables successful brute force attacks
Solution Approach 1:
The patent substitutes quantum physical processes for computational algorithms in random number generation. By using quantum phenomena such as photon detection or quantum state measurement, the system generates keys that are fundamentally unpredictable and cannot be cracked through computational brute force, thereby neutralizing the threat posed by increasing attacker computing power while maintaining efficiency
3Ease of manufacture
If pseudo-random number generation with known algorithms is used, then the generation process is reproducible for debugging and testing, but this reproducibility becomes a security vulnerability when attackers gain access to the algorithm
Solution Approach 1:
The patent replaces algorithmic pseudo-random generation with quantum physical processes that are inherently non-algorithmic and non-reproducible. The measurement of quantum states such as photon polarization or vacuum fluctuations produces outcomes that cannot be predicted or reproduced even with complete knowledge of the system, thereby eliminating the security vulnerability of algorithmic reproducibility while maintaining ease of key generation
Solution Approach 2:
The patent introduces quantum mechanical measurement as an intermediary between the physical world and the digital session key generation process. This quantum measurement process acts as a mediator that converts inherently random quantum phenomena into usable random numbers, providing a bridge that maintains both ease of generation and unpredictability
