Solution Overview

Problem

Existing hearing device systems face challenges in securing wireless communication between entities, particularly due to the use of open standard-based interfaces which are vulnerable to security threats.

Innovation Solution

A method for creating a trusted bond between a hearing device and a user application involves obtaining authentication material, transmitting authentication requests, verifying authentication data, and storing authentication keys, ensuring secure and efficient pairing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If open standard-based wireless communication interfaces are used in hearing device systems, then ease of operation and compatibility are improved, but security is worsened due to vulnerability to security threats

Engineering Contradiction:

Improveease of pairingVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary authentication actions during the pairing process by obtaining authentication material, verifying authentication data, and storing authentication keys before establishing the wireless connection. This preliminary security verification ensures that only authorized devices can connect, resolving the contradiction between ease of operation and security by making security checks an integral part of the pairing process rather than an afterthought.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces authentication material and authentication keys as intermediary elements between the hearing device and the external device. These intermediaries facilitate secure communication by acting as mediators that verify identities and establish trusted relationships, allowing open standard interfaces to maintain both ease of operation and security through the intermediary authentication mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If authentication keys are transmitted between devices during pairing, then connection establishment is simplified, but security is worsened due to exposure to replay attacks

Engineering Contradiction:

Improvepairing efficiencyVSAvoidreplay attacks

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the authentication key transmission from the communication channel by implementing local authentication verification. Instead of transmitting authentication keys between devices, the system obtains authentication material, performs verification locally, and stores keys securely without exposing them to transmission channels, thereby eliminating the vulnerability to replay attacks while maintaining pairing efficiency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies preliminary anti-action by implementing authentication verification before any key transmission or connection establishment. The system verifies authentication data and validates identities prior to establishing communication, preventing replay attacks from occurring in the first place rather than attempting to detect or respond to them after transmission.

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If multiple authentication methods are implemented, then security is improved by protecting against various threats, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal authentication framework that can handle multiple authentication methods through a single integrated process. The system obtains authentication material, verifies authentication data, and manages authentication keys in a unified manner that supports different authentication types, thereby improving security against various threats without proportionally increasing device complexity through separate dedicated systems for each method.

Inventive Principle:

Principle #6Universality (Multi-functionality)
