Solution Overview

Problem

Existing encryption methods are vulnerable to quantum computers and advances in mathematics, as they rely on insecure key generation and distribution, particularly due to the mathematical hardness of algorithms and the use of pseudo-random number generators that can be predicted.

Solution Approach 1:

The patent replaces pseudo-random number generators (software-based deterministic systems) with quantum random number generators (physics-based probabilistic systems). This substitution uses fundamental quantum mechanical effects to generate truly random numbers that cannot be predicted by mathematical analysis or quantum computation, thereby resolving the security vulnerability while maintaining efficiency through hardware implementation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of randomness generation from deterministic algorithmic processes to probabilistic quantum measurements. By measuring quantum states (such as photon polarization or electron spin), the system produces random numbers with provable unpredictability, transforming the nature of randomness from classical to quantum and eliminating predictability vulnerabilities.

If asymmetric encryption schemes are used, then key distribution is simplified, but the mathematical hardness has no rigorous proof against quantum attacks

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent converts the vulnerability of asymmetric encryption (mathematical hardness without rigorous proof) into a benefit by using quantum mechanics to provide information-theoretic security. Instead of relying on unproven mathematical assumptions, the system uses quantum random number generation to create keys with provable security based on the laws of physics, making the system resistant to both classical and quantum attacks.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent segments the encryption system into two distinct components: quantum random number generation for key creation and symmetric encryption for data protection. This separation allows each component to be optimized independently, with the quantum RNG providing unbreakable randomness and the symmetric cipher providing efficient encryption, together achieving both ease of operation and quantum resistance.

Solution Approach 1:

The patent implements a quantum random number generator that continuously generates random numbers at high rates, eliminating the need for manual key management or complex storage systems. The system produces keys on-demand with such high entropy and speed that standard storage and management protocols remain sufficient, and the continuous generation capability allows for easy key rotation without increasing operational complexity.

AI summary

A system and method for encryption key generation by receiving a plaintext message having a fixed character length and receiving, from a source, a plurality of random number. A matrix is created from the plurality random numbers and has at least one of the number of rows or columns equal to or greater than the character length. An array that can be used as an encryption key or a seed for an encryption key is generated by selecting an initial element within the matrix, selecting subsequent elements using a selection technique until a number of elements in the array is equal to the character length and rejecting any previously selected elements from the array.
