Communication Device Dynamic Timeout for Secure Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses lack appropriate control over the timeout time in connection setting modes, leading to potential unintended connections and security risks due to prolonged operation in an insecure connection setting state.
Innovation Solution
The timeout time of the connection setting mode is controlled based on the completion time of the initial setting process, extending it if necessary to accommodate user operations, thereby ensuring secure and timely transition out of the connection setting mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the timeout time of the connection setting mode is extended to accommodate user operations, then user convenience is improved, but security risks increase due to prolonged operation in an insecure state
Solution Approach 1:
The timeout time is made dynamic rather than fixed. The control unit extends the timeout time based on the actual completion time of the initial setting process, allowing the system to adapt the connection setting mode duration to actual user needs while automatically returning to a secure state when no longer needed.
Solution Approach 2:
The timeout parameter is changed from a fixed value to a variable value that depends on the completion time of the initial setting process. This allows the system to optimize the balance between user convenience and security by adjusting the timeout duration based on actual operational requirements.
2Object-affected harmful factors
If the timeout time is shortened to improve security, then security risks are reduced, but user convenience deteriorates due to insufficient time for completing initial settings
Solution Approach 1:
The system uses dynamic timeout adjustment based on the actual duration of the initial setting process. This ensures that the timeout is never shorter than necessary for completing user operations, while also ensuring it doesn't extend longer than needed, thus maintaining security.
Solution Approach 2:
The control unit monitors the completion time of the initial setting process and uses this feedback to appropriately set the timeout time. This feedback mechanism ensures the timeout is optimized based on actual operational requirements rather than using a fixed conservative or aggressive value.
3Device complexity
If a fixed timeout time is used for the connection setting mode, then system simplicity is maintained, but adaptability to different user operation durations is reduced
Solution Approach 1:
The timeout parameter is changed from a fixed value to a variable value that adapts to different user operation durations. This is achieved by calculating the timeout based on the actual completion time of the initial setting process, allowing the system to handle various scenarios appropriately.
Solution Approach 2:
The system transitions from a static fixed timeout to a dynamic timeout that automatically adjusts based on the actual duration of user operations. This dynamic adjustment provides adaptability without requiring complex user configuration or manual intervention.

AI summary
A communication apparatus includes a control unit configured to perform, in a case where the communication apparatus is operating in a connection setting mode and a predetermined process is completed, control to stop operation in the connection setting mode based on passage of a second time longer than a first time without performance of connection setting from a start of an operation of the communication apparatus in the connection setting mode.
