Relay Device Multiple Authentication Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication relay devices often fail to connect authorized users to a network due to communication failures or incorrect settings, leading to inconvenience, as they rely on a single method for authentication, which can result in denial of service even for legitimate users.
Innovation Solution
A relay device that employs multiple authentication methods in a predetermined or user-allocated order, ensuring connection when at least one method yields a positive determination, thereby reducing user inconvenience and security risks by avoiding lower security method applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single authentication method is used, then the device complexity is reduced, but the reliability of connection permission is worsened because authorized users may be denied connection due to communication failures or incorrect settings
Solution Approach 1:
The authentication process is segmented into multiple independent determination methods (first determination method and second determination method). Each method operates independently to evaluate connection permission, so that failure in one method does not prevent successful authentication through another method. This segmentation resolves the contradiction by maintaining reliability while managing complexity through modular design.
Solution Approach 2:
The system performs preliminary actions by pre-configuring multiple determination methods and establishing a predetermined execution order before authentication is needed. The relay device stores multiple authentication methods and their execution priorities in advance, so when connection permission is determined, the system can efficiently execute appropriate methods without complex real-time decision-making, thus improving reliability while controlling complexity.
2Reliability
If multiple authentication methods are applied, then the reliability of connection permission is improved, but the device complexity increases due to multiple determination methods and execution order management
Solution Approach 1:
The system implements dynamic execution by determining the execution order of multiple authentication methods based on predetermined criteria or conditions. The relay device can flexibly select which determination method to execute first or next, adapting to different authentication scenarios. This dynamic approach allows the system to manage complexity by executing only necessary methods while maintaining high reliability through multiple available options.
Solution Approach 2:
The system changes parameters by adjusting the execution order and selection criteria of authentication methods based on different situations. The relay device can modify which determination method is applied first or whether to apply multiple methods, depending on factors like security requirements or communication conditions. This parameter adjustment allows the system to optimize between reliability and complexity for different operational contexts.
3Object-affected harmful factors
If higher security authentication methods are prioritized, then the security level is improved, but the ease of operation is worsened due to more stringent authentication requirements
Solution Approach 1:
The system applies partial action by selectively executing authentication methods based on what is necessary for each connection request. Not all determination methods are executed for every authentication attempt - the system chooses appropriate methods based on predetermined order and conditions. This allows high security to be maintained through available rigorous methods while improving ease of operation by avoiding unnecessary authentication steps.
Solution Approach 2:
The system uses simpler, faster authentication methods as fallback options when higher security methods are not required or fail. These less stringent methods act as disposable alternatives that can quickly resolve authentication without requiring complex security checks, thus maintaining security where needed while improving ease of operation when appropriate.

AI summary
Connection determination methods are applied to determine whether relay of communication between one or more wireless communication devices and a wireless communication device which is different from the communication devices is permissible, and when a positive determination result is obtained by applying at least one of the methods, the relay is permitted by applying at least one of the methods. When the relay of communication is permitted by the permissible connection determination, the relay is executed.
