Communication Device Access Mode Switching and Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices require complex authentication processes for access control, which can lead to security vulnerabilities due to password leakage and increased costs when implementing password change functions, while existing solutions do not effectively manage access permissions.
Innovation Solution
A communication device with a processing circuitry that switches between restricted and unrestricted access modes, allowing no-permission devices to access by registering them as permission devices in the unrestricted mode, thereby simplifying access and enhancing security without the need for manual authentication input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ID and password authentication is implemented for access control, then security is improved, but operation complexity increases and costs increase when password change function is added
Solution Approach 1:
The patent extracts the authentication mechanism from traditional ID/password systems and replaces it with a push-button based mutual authentication system. The communication device and operation device each have authentication buttons that, when pressed simultaneously, establish trusted connection without requiring users to input or manage passwords, thus maintaining security while eliminating operational complexity
Solution Approach 2:
The patent uses temporary authentication tokens generated through push-button interaction instead of permanent passwords. These temporary credentials are automatically invalidated after use or after a short period, eliminating the need for password change functions and reducing device complexity while maintaining security
2Reliability
If access control is implemented using ID and password, then security is improved, but ease of operation deteriorates due to manual input requirements
Solution Approach 1:
The authentication system performs self-service through automatic mutual authentication between devices. When the authentication buttons are pressed, the system automatically generates and exchanges authentication credentials without requiring manual input of ID or password, making the process as easy as pressing a button while maintaining security
Solution Approach 2:
The patent replaces the mechanical input system (keyboard entry of ID/password) with a simple push-button mechanical action. This substitution transforms a complex multi-step manual authentication process into a single-button press operation, dramatically improving ease of operation while maintaining security through automated credential exchange
3Reliability
If password change function is added to prevent leakage, then security is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements preliminary authentication through push-button interaction that establishes trusted connections before any data exchange. This preliminary action creates secure sessions that are automatically managed and invalidated, eliminating the need for password change functions while maintaining security against credential leakage
Solution Approach 2:
The patent changes the authentication parameter from static passwords to dynamic temporary tokens generated through push-button interaction. These tokens have limited validity periods and are automatically renewed or invalidated, providing security against leakage without requiring password change functionality, thus reducing device complexity
4Ease of operation
If automatic communication connection authentication is performed, then ease of operation is improved, but access permission control is insufficient
Solution Approach 1:
The patent segments the authentication process into two distinct phases: connection authentication (automatic) and access permission authentication (manual button press). The automatic connection phase establishes communication channels, while the separate manual authentication phase controls actual access permissions, thereby maintaining ease of connection while improving access control reliability

AI summary
A communication device that includes processing circuitry that receives an input to switch an operation mode between a first operation mode in which access to the communication device or a connected device connected to the communication device is restricted and a second operation mode in which access is not restricted; controls the access from devices that transmitted access requests in accordance with the first operation mode or the second operation mode, which is designated by the received input; and permits a no-permission device that has no permission for the access to access the communication device or the connected device based on an access request from the no-permission device by registering the no-permission device as a permission device, in a case where the operation mode is the second operation mode.
