Solution Overview

Problem

Current encryption algorithms face challenges in securing data communications due to vulnerabilities in encryption keys, which can be easily obtained by unauthorized parties, necessitating improved key generation and encryption methods.

Innovation Solution

A symmetric frequency-based encryption algorithm is employed, where encryption keys are generated based on a reference signal comprising multiple frequencies, with values assigned to these frequencies and their attributes, enabling secure encryption and decryption of data using existing algorithms like AES.

1Reliability

If traditional encryption algorithms are used, then data can be encrypted and decrypted, but encryption keys can be easily obtained by unauthorized parties through brute-force search and dictionary methods

Solution Approach 1:

The patent transforms the encryption key from a static string into a dynamic signal with multiple parameters including frequency, amplitude, phase, and duration. Each character of the passphrase corresponds to specific signal parameters, creating a multi-dimensional key space that is computationally infeasible to brute-force. The encrypted data includes both the ciphertext and the signal parameters needed for decryption, making traditional key extraction methods ineffective.

If encryption keys are made more complex to resist attacks, then security improves, but key generation and management becomes more difficult

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically generates the encrypted signal from the user's passphrase using deterministic algorithms. The signal parameters (frequencies, amplitudes, phases) are computed directly from the passphrase characters, eliminating the need for users to manually create or manage complex keys. The same passphrase always generates the same signal, providing reproducibility without increasing operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediary encryption signal that acts as a bridge between the simple user passphrase and the complex encryption requirements. Instead of directly using the passphrase as a key, the system converts it into a structured signal with specific temporal and spectral characteristics. This intermediary representation maintains security while simplifying user interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and method for implementing an encryption technique by combining matrix mathematics, audio frequencies, and symmetric key. Data encryption/decryption may be performed using symmetric key based implementations, with the encryption keys being derived from unique sequences of frequencies (e.g., either in written or audible form). In this regard, the encryption key may be derived from a reference signal, which may comprise a plurality of different frequencies, and the generating of the encryption key is based on assigning values to the plurality of different frequencies and/or to one or more attributes associated with the reference signal or elements (e.g., particular portions, such as notes or frequencies) thereof. The data may then be encrypted based on the generated encryption key, wherein the encrypting of the data comprises encrypting plaintext values. The encryption/decryption may be performed directly, based on the symmetric frequency-based key generation, and/or in conjunction with existing encryption algorithms (e.g., AES).
