Terminal Authentication via Intermediary Short-Range Link

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems require terminal apparatuses to be within a predetermined range to be authenticated, which is inconvenient for users as they must physically move to authenticate, and if a terminal apparatus cannot acquire positional information, it cannot participate in communication, affecting security and user convenience.

Innovation Solution

A terminal apparatus equipped with both long-distance and short-range communication systems, where if it cannot acquire positional information, it requests authentication from another authenticated terminal apparatus using the short-range communication system, allowing it to participate in communication and enhance security and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If terminal apparatuses use long-range radio communication systems for authentication, then communication coverage is expanded, but authentication reliability deteriorates when positional information cannot be acquired

Engineering Contradiction:

Improvecommunication coverageVSAvoidauthentication reliability

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The terminal apparatus dynamically switches between long-range and short-range communication systems based on the availability of positional information. When positional information is unavailable, the system transitions to using another terminal apparatus as an authentication station via short-range communication, thereby maintaining authentication reliability while preserving long-range communication capability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Another terminal apparatus serves as an intermediary authentication station when the original authentication station cannot authenticate due to lack of positional information. This intermediary terminal performs authentication using short-range communication, bridging the gap between the unauthenticated terminal and the network.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If terminal apparatuses must be within a predetermined range to be authenticated, then authentication security is improved, but user convenience deteriorates as users must physically move to authenticate

Engineering Contradiction:

Improveauthentication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

When a terminal apparatus cannot acquire positional information, another authenticated terminal apparatus acts as an intermediary to perform authentication. This eliminates the need for the user to physically move to a predetermined range, significantly improving user convenience while maintaining security through the intermediary's authenticated status.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables terminal apparatuses to perform authentication services for each other. An authenticated terminal can serve as an authentication station for another terminal that cannot acquire positional information, creating a self-service authentication mechanism that improves convenience without compromising security.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If terminal apparatuses use short-range communication systems for authentication, then user convenience is improved when positional information is unavailable, but communication distance is limited

Engineering Contradiction:

Improveuser convenienceVSAvoidcommunication distance

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The terminal apparatus dynamically selects the appropriate communication range based on the authentication scenario. It uses long-range communication when positional information is available for direct authentication, and switches to short-range communication only when another terminal must serve as an intermediary, thus minimizing the limitation of communication distance.

Inventive Principle:

Principle #15Dynamics

AI summary

An acquiring unit acquires the positional information. A first request unit requests an authentication station to perform authentication by using the positional information acquired by the acquiring unit. When the authentication station grants authentication for a request from the first request unit, a communication processing unit carries out communications using a first radio communication system. When authentication required for carrying out the communications using the first radio communication system is not performed in the communication processing unit, a second request unit requests another terminal apparatus to perform authentication by using a second radio communication system, whose transmission distance is shorter than the first radio communication system.
