Communication Device Permission Processing for Ad-Hoc Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face security risks when automatically connecting devices to ad-hoc networks through short-range radio communication, as devices can be invisible due to shields like walls, potentially allowing unauthorized access.
Innovation Solution
A communication system comprising multiple radio communication units operating within different ranges, where a second communication unit receives setting information to establish communication with a first communication unit, and a permission processing unit generates communication permission information to ensure secure connections within overlapping communication areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic connection permission is provided through short-range radio communication, then connection convenience is improved, but security deteriorates because devices can be invisible due to shields like walls
Solution Approach 1:
The patent introduces a permission notification unit that acts as an intermediary between the communication units and the permission granting process. This intermediary ensures that connection permission is only granted after the user is notified and explicitly approves, preventing unauthorized connections while maintaining automatic connection capabilities for approved devices
Solution Approach 2:
The system implements feedback through notification to the user about connection permission requests. The user's response (approval or rejection) feeds back into the permission processing unit, which then determines whether to grant connection permission. This feedback loop ensures security while maintaining ease of operation for legitimate connections
2Speed
If communication permission is automatically granted within short-range communication area, then connection speed is improved, but security deteriorates due to potential unauthorized access
Solution Approach 1:
The system performs preliminary actions by notifying the user of connection permission requests before actual connection is established. This preliminary notification allows the user to approve or reject connections in advance, ensuring security is checked before the connection process completes, thus preventing unauthorized access while maintaining fast connection speeds for approved devices
3Ease of operation
If devices can connect without visibility confirmation, then ease of connection is improved, but security deteriorates as invisible devices may be unauthorized
Solution Approach 1:
The permission notification unit serves as an intermediary that mediates between automatic connection capabilities and security requirements. It ensures that even though devices can connect automatically within range, the user is notified and can block unauthorized devices, thus preventing harmful factors while maintaining ease of connection
Solution Approach 2:
The system enables users to manage their own connection permissions through the notification mechanism. Users can review connection requests and grant or deny permission based on their judgment, providing self-service security control that prevents unauthorized access while maintaining easy connection for legitimate devices
