Wireless Network Fusion Authentication Reuse

Solution Overview

Problem

In wireless network fusion technologies, redundant authentication is required when switching between different wireless communication networks, leading to cumbersome user experiences and inefficiencies, particularly in applications like UAV communications where secure pairing is often assumed across multiple environments without considering the existence of various wireless systems.

Innovation Solution

A wireless communication method that performs authentication information exchange in a first secure communication, followed by network fusion, allowing seamless switching to a second wireless network using the exchanged authentication information without re-authentication, thereby establishing a secure communication in the new network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If security authentication is performed for each wireless network switch, then communication security is improved, but user convenience and communication efficiency deteriorate due to redundant authentication

Engineering Contradiction:

Improvecommunication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent performs security authentication in advance during the first network connection and stores the authentication result. When switching to a second wireless network, the stored authentication result is reused, eliminating the need for re-authentication. This preliminary action ensures security while improving user convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a unified authentication mechanism that works across multiple wireless networks (first and second networks). The authentication result obtained in one network context is made universally applicable to another network context, allowing the same authentication to serve multiple network switching scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If security authentication is performed for each wireless network switch, then communication security is improved, but communication efficiency deteriorates due to repeated authentication processes

Engineering Contradiction:

Improvecommunication securityVSAvoidcommunication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent performs security authentication in advance during the first network connection and stores the authentication result. When switching to a second wireless network, the stored authentication result is reused, eliminating the need for re-authentication. This preliminary action ensures security while improving user convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuous secure communication by preserving the authentication state across network switches. Instead of interrupting communication for re-authentication, the system continuously utilizes the previously established authentication, ensuring both security and efficiency.

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If authentication information is exchanged in a first secure communication, then seamless network switching is enabled, but security risks may increase if authentication information is compromised

Engineering Contradiction:

Improveseamless network switchingVSAvoidsecurity risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a secure communication channel as an intermediary for exchanging authentication information. This intermediary channel protects the authentication data during transmission between devices, reducing security risks while enabling seamless network switching.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs security authentication in advance during the first network connection and stores the authentication result. When switching to a second wireless network, the stored authentication result is reused, eliminating the need for re-authentication. This preliminary action ensures security while improving user convenience.

Inventive Principle:

AI summary

A wireless communication method includes performing authentication information exchange, performing network fusion, and performing network fusion secure communication. Performing authentication information exchange includes establishing a first secure communication in a first wireless network between a first apparatus and a second apparatus and exchanging authentication information between the first apparatus and the second apparatus. Performing network fusion includes switching from the first wireless network to a second wireless network different from the first wireless network. Performing network fusion secure communication includes establishing a second secure communication in the second wireless network between the first apparatus and the second apparatus using the authentication information exchanged during the authentication information exchange through the first secure communication.
