Random Number Generation via Storage Access Timing Variations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computers have limited ability to generate truly random and unpredictable numbers, which is crucial for data security but is compromised by their deterministic nature, making existing random number generation methods vulnerable.
Innovation Solution
A system that utilizes the minute unpredictable variations in data storage medium access times to generate random numbers, either by seeding pseudo-random number generators (PRNGs) or directly producing true random numbers (TRNGs) through a random number module that monitors and records these access times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If computers use deterministic algorithms to generate random numbers, then the generation process is efficient and controllable, but the unpredictability and security are compromised
Solution Approach 1:
The patent introduces a random number module as an intermediary component that bridges the deterministic computer system and the unpredictable physical world. This module captures timing variations from data storage operations and converts them into random number seeds, allowing the main computer system to remain deterministic while incorporating true randomness through the intermediary module.
Solution Approach 2:
The patent replaces traditional mechanical or software-based random number generation with a hybrid approach that substitutes physical measurement (timing variations in data storage operations) for algorithmic generation. By measuring actual physical timing variations in data storage medium access, the system obtains true randomness without relying on deterministic algorithms.
2Productivity
If computers follow rigid instructions, then processing is efficient and predictable, but random number generation capability is limited
Solution Approach 1:
The patent segments the random number generation function into a separate random number module distinct from the main deterministic processing system. This segmentation allows the main system to maintain high processing efficiency with rigid instructions, while the specialized module handles random number generation using timing variations, thus resolving the conflict between efficiency and randomness quality.
3Reliability
If traditional random number methods are used, then implementation is simple, but security vulnerabilities arise
Solution Approach 1:
The patent makes the data storage medium serve multiple functions: it acts as both the storage device for data and the source of randomness through timing variations. This multi-functionality eliminates the need for separate hardware random number generators, thereby improving security through true randomness while minimizing additional system complexity.

AI summary
The disclosure is related systems and methods for using operation durations of a data storage medium to generate random numbers. In one embodiment, a device may comprise a random number generator circuit configured to store a value representing a duration of an operation on the data storage medium, and generate a random number based on the value. Another embodiment may be a method comprising recording durations of access operations to a data storage medium, and generating a random number based on the durations.
