Processor Noise Encryption via Coherence Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Processor-related noise, often produced by voltage regulators, can interfere with operations and is not effectively encrypted, leading to coherence issues that may compromise sensitive information.
Innovation Solution
An apparatus and method that involve a frequency selection module, amplitude selection module, and noise scrambling module to produce a first noise output that combines with processor-related noise, ensuring coherence between the combined noise output and processor operations is below a threshold, using one or more second voltage regulating modules and loads to vary the noise output based on coherence levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage regulators are used to power the processor, then the processor can operate, but processor-related noise is produced that may compromise sensitive information
Solution Approach 1:
The patent generates additional noise through second voltage regulating modules and loads that combines with the original processor-related noise. This converts the harmful noise into a beneficial encryption mechanism, where the combined noise obscures the correlation between noise patterns and processor operations, thereby protecting sensitive information while maintaining processor functionality
Solution Approach 2:
The patent introduces second voltage regulating modules and loads as intermediary components that generate a first noise output. This intermediary noise acts as a mediator that combines with the second noise output from the first voltage regulating modules, creating a third noise output that encrypts the relationship between noise and processor operations without interfering with processor power supply
2Loss of information
If noise encryption is implemented to protect sensitive information, then security is enhanced, but device complexity increases
Solution Approach 1:
The second voltage regulating modules and loads serve multiple functions: they provide additional power regulation for the processor while simultaneously generating the first noise output for encryption purposes. This multi-functionality reduces device complexity by combining noise encryption capabilities with existing power management infrastructure
Solution Approach 2:
The system uses the same voltage regulating modules and loads to serve dual purposes of power delivery and noise generation. The components essentially serve themselves by performing both their primary power regulation function and the secondary noise encryption function, eliminating the need for separate dedicated noise generation hardware

AI summary
An apparatus for encrypting processor related noise is disclosed. A method and a computer program product also perform the functions of the apparatus. The apparatus includes a frequency selection module that selects frequencies for a first noise output. The frequencies are within a range of frequencies of a second noise output. The second noise output is produced by one or more first voltage regulating modules providing power to a processor. The apparatus includes an amplitude selection module that selects an amplitude for each frequency of the first noise output. The apparatus includes a noise scrambling module that produces the first noise output based on one or both of the frequency selection module and the amplitude selection module. The first noise output combines with the second noise output to produce a third noise output such that coherence between the third noise output and operations of the processor is below a threshold.
