Solution Overview

Problem

Wireless authentication systems are vulnerable to unauthorized access as they respond to anyone possessing the authenticator, allowing third parties to access secured areas or vehicles even if the authenticator is stolen or copied.

Innovation Solution

A wireless authentication interference unit that detects the authentication protocol between an authentication terminal and an authentication key, and outputs an interference signal during the authentication message broadcast, disrupting the authentication process to prevent unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless authentication systems are used to replace physical key systems, then convenience and ease of operation are improved, but security against unauthorized access deteriorates because the system responds to anyone possessing the authenticator

Engineering Contradiction:

Improveconvenience of authenticationVSAvoidsecurity against unauthorized access

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The interference unit proactively detects authentication requests and transmits interfering signals before the legitimate authenticator can complete its authentication sequence. This preliminary anti-action prevents the authentication terminal from verifying the stolen authenticator's response, thereby resolving the contradiction by maintaining convenience for legitimate users while blocking unauthorized access attempts

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The interference unit acts as an intermediary between the stolen authenticator and the authentication terminal. It receives authentication requests from the terminal and transmits interfering signals that prevent the terminal from correctly receiving or verifying the authenticator's response, thus mediating the interaction to maintain security while preserving user convenience

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enhances security by confusing the authentication system, making it impossible for the authentication terminal to verify the response signal, thereby preventing unauthorized access and providing an additional layer of security.
