Communication Device Authentication for Secure Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless connection techniques allow third parties to establish connections between devices without proper authentication, potentially leading to unauthorized access.
Innovation Solution
A communication device with a processor, output unit, and wireless interface that authenticates users by accepting inputted authentication information, outputs specific information using a public key, and establishes a wireless connection only after successful authentication, preventing unauthorized connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless connection establishment is automated without authentication, then connection speed and ease of operation are improved, but security and reliability deteriorate due to unauthorized access
Solution Approach 1:
The communication device performs preliminary user authentication before allowing any wireless connection establishment. The authentication process occurs in advance (before connection) and includes verifying user credentials and checking authentication state, ensuring that only authorized users can initiate connection procedures.
Solution Approach 2:
The system implements feedback mechanisms where the communication device monitors authentication state and connection status, then adjusts its behavior accordingly. When authentication fails or is not performed, the device provides feedback by rejecting connection requests. The authentication response mechanism provides feedback to external devices about whether authentication was successful.
2Reliability
If user authentication is required before wireless connection, then connection security is improved, but operation complexity and connection time increase
Solution Approach 1:
The communication device performs self-service authentication by automatically managing its own authentication state and responding to authentication requests without requiring manual intervention. The device monitors its own authentication status and automatically adjusts its behavior regarding connection establishment, reducing the operational burden on users while maintaining security.
3Reliability
If authentication state monitoring is implemented, then unauthorized connection prevention is improved, but processing time and energy consumption increase
Solution Approach 1:
The communication device periodically monitors its authentication state rather than continuously processing authentication requests. The authentication monitoring occurs at specific intervals or triggered by events (such as receiving a connection request), reducing energy consumption while maintaining effective security monitoring.

AI summary
A communication device may accept an input of user authentication information, cause an output unit to output specific information obtained by using a public key in a case where authentication using the inputted user authentication information is successful. In a case where the authentication using the inputted user authentication information fails, the specific information is not outputted. The communication device may receive an authentication request in which the public key is used from a first external device, send an authentication response to the first external device, receive first connection information from the first external device, and establish a first wireless connection between the communication device and a second external device by using the first connection information.
