Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryptographic protocols face challenges in generating fresh, secure, non-algorithmic randomness for remote communication, particularly due to the limitations of quantum physics-based solutions which are expensive and require specialized equipment, and existing algorithmic methods that lack understanding of randomness.
Innovation Solution
A physical contraption, such as the RandoSol apparatus, generates shared randomness through deterministic complexity by using identical physical devices operated under identical conditions, producing a shared outcome that is considered effective physical randomness, ensuring secure communication over insecure channels through physical redundancy, data reduction, and variance elimination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum physics-based solutions are used to generate secure randomness, then security and randomness quality are improved, but cost and equipment complexity increase
Solution Approach 1:
The patent replaces quantum physics mechanisms with a classical mechanical system consisting of rotating discs with holes, fluid flow, and conductivity measurement. This mechanical approach generates cryptographic-grade randomness without requiring quantum equipment, thereby reducing device complexity and cost while maintaining security and randomness quality.
2Device complexity
If algorithmic methods are used to generate randomness, then device complexity is reduced, but randomness quality and security understanding deteriorate
Solution Approach 1:
The patent replaces algorithmic software-based randomness generation with a physical mechanical system that produces true entropy through unpredictable physical processes (fluid flow through rotating discs, bubble formation, conductivity variations). This provides both simplicity and high-quality randomness grounded in physical phenomena rather than computational algorithms.
Solution Approach 2:
The mechanical system is self-powered and self-regulating, using the fluid flow and physical interactions to automatically generate randomness without requiring complex control algorithms or external computational resources. The system serves itself by converting physical energy directly into cryptographic entropy.
3Reliability
If identical physical contraptions are used to generate shared randomness, then security and randomness quality are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates a feedback mechanism where the measured conductivity signal is used to verify and adjust the randomness generation process. This feedback allows the system to compensate for minor manufacturing variations between duplicate contraptions, ensuring that all devices generate consistent, shareable randomness even with slight manufacturing tolerances.
Solution Approach 2:
The system uses multiple adjustable parameters (fluid flow rate, disc rotation speed, hole configurations, electrode positions) that can be tuned to optimize performance and accommodate manufacturing variations. By changing these parameters, the system maintains robust shared randomness generation across duplicate devices with normal manufacturing tolerances.

AI summary
A stack of rotating discs drilled with randomized holes allow a light fluid L to rise into a chamber filled with heavier fluid H, as a randomized stream of bubbles. The two fluids are mutually non-soluble, and of different electric conductivity, hence the randomized stream of bubbles generates a randomized curve of electrical resistance within the chamber, over time; this output resistance curve is shared by all parties that have a duplicate of the contraption and apply the same activation settings. The physical complexity of the contraptions keeps the randomness secure against all parties not in possession of the contraption. Unlike Entanglement and BB84 solutions, this invention generates shared randomness without communicating the same between the parties.
