Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pseudo-random number generation is used for session key generation, then session authentication can be established, but the session keys become susceptible to brute force attacks as computing power increases

Engineering Contradiction:

Improvesession key securityVSAvoidvulnerability to brute force attacks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces classical pseudo-random number generation (mechanical/computational system) with quantum random number generation (quantum physical system). The randomness source shifts from algorithmic computation to fundamental quantum uncertainty, making the session keys unpredictable even with unlimited computing power. This substitution resolves the vulnerability to brute force attacks while maintaining session authentication functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of randomness generation from computational complexity to quantum physical properties. By utilizing quantum mechanical principles (such as quantum superposition and measurement collapse) instead of computational algorithms, the system achieves true randomness that cannot be reproduced or predicted, thereby enhancing security against attacks that exploit patterns in pseudo-random generation.

2Reliability

If quantum bits are transmitted using private sets of quantum bases, then true randomness is achieved, but the system complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a dedicated quantum random number generation system as an intermediary component between the session authentication protocol and the randomness source. This separate quantum module (with its own basis determination circuitry and qubit generation capabilities) acts as a specialized mediator that provides true randomness without requiring the main authentication system to handle quantum complexity directly, thereby isolating and managing the system complexity.

Inventive Principle:

3Device complexity

If traditional pseudo-random generation methods are used, then the system remains simple, but the session keys can be replicated by attackers with sufficient computing resources

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent segments the session authentication system into distinct functional modules: a classical session management component and a separate quantum random number generation component. This segmentation allows the majority of the system to remain simple and classical, while only the critical randomness generation function is enhanced with quantum technology. The modular approach minimizes the impact on overall system complexity while improving key unpredictability.

AI summary

Systems, apparatuses, methods, and computer program products are disclosed for facilitating on-demand delivery of unknown qubits. An example method includes determining a first quantum basis pattern. The example method further includes encoding, by encoding circuitry, a set of bits utilizing the first quantum basis pattern to generate a set of qubits and transmitting, by quantum communications circuitry, the set of qubits over a quantum line, for example, a polarization maintaining optical fiber, to a remote device, wherein the set of qubits is configured for measurement by an independently determined, second quantum basis pattern, resulting in a second set of bits different than the first set of bits.
