Solution Overview

Problem

There is a growing concern for the security of audio data in human-computer interactions, as malware can intercept and access private audio communications, compromising user privacy.

Innovation Solution

A system is implemented that establishes a cryptographically secure communication protocol between an application module and an audio module, using a mutually trusted module to facilitate key exchange and ensure secure data transmission, thereby preventing unauthorized access to audio data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If audio data is transmitted without encryption, then communication efficiency is maintained, but security and privacy are compromised

Engineering Contradiction:

Improveaudio data securityVSAvoidcommunication protocol complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by establishing cryptographic keys and securing the communication channel before audio data transmission begins. The mutually trusted module pre-configures encryption parameters and authentication mechanisms, so that when audio data flows through the channel, security is already in place without adding real-time processing complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a mutually trusted module as an intermediary between the application module and audio module. This mediator handles the complex cryptographic operations and key management, shielding the audio data transmission from direct exposure to security mechanisms while maintaining encrypted communication channels.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a mutually trusted module is introduced to facilitate secure communication, then security is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication securityVSAvoidsystem architecture complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mutually trusted module is designed with multi-functionality, serving as both a security gateway and a communication coordinator. It performs key exchange, authentication, and encrypted data routing within a single integrated component, reducing the need for separate security subsystems and minimizing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mutually trusted module implements self-service mechanisms by automatically managing cryptographic key pairs, performing mutual authentication, and handling session establishment without requiring manual configuration or external intervention. This automation reduces the operational complexity of deploying and maintaining secure audio communication.

Inventive Principle:

Principle #25Self-service

AI summary

Systems and methods include establishing a cryptographically secure communication between an application module and an audio module. The application module is configured to execute on an information-handling machine, and the audio module is coupled to the information-handling machine. The establishment of the cryptographically secure communication may be at least partially facilitated by a mutually trusted module.
