Wireless AP Certificate Access for Limited-Service Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals without a password often cannot connect to wireless access points installed by service providers in areas with poor or no cellular service, hindering access to necessary information or services.
Innovation Solution
A pre-registration process allows entities to obtain certificates that enable time-limited connections to wireless access points through authorized applications, bypassing the need for passwords by using digital certificates and time-limited tokens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless access points require password authentication for connection, then network security is improved, but ease of operation deteriorates for users in areas with poor cellular service
Solution Approach 1:
The system performs preliminary authentication by obtaining digital certificates from authorized entities before the actual connection is needed. These certificates are stored and automatically presented when connection is required, eliminating the need for real-time password entry and enabling seamless connection in areas with poor cellular service.
Solution Approach 2:
Digital certificates serve as an intermediary authentication mechanism between the wireless device and the access point. Instead of direct password authentication, the certificate acts as a mediator that proves authorization, allowing secure connection without requiring users to remember or enter passwords.
2Ease of operation
If universal access to wireless access points is provided, then ease of operation is improved, but security control deteriorates
Solution Approach 1:
The system implements location-based access control where digital certificates are tied to specific geographic locations or access points. Authorized entities receive certificates that are valid only for specific destinations, enabling easy access at authorized locations while maintaining security control through location-specific validation.
Solution Approach 2:
The authentication system changes from static password-based access to dynamic certificate-based access with time and location parameters. Certificates contain embedded parameters such as valid time periods and authorized destinations, allowing the system to provide universal access within defined parameters while maintaining security control.
3Reliability
If time-limited connection tokens are implemented, then security control is improved, but device complexity increases
Solution Approach 1:
The system extracts the authentication credentials from the main connection process by using separate digital certificate files. The certificate contains all necessary authentication information including time limits and destination restrictions, allowing the complex security logic to be contained within the certificate itself rather than requiring complex processing during connection establishment.
Data Source
AI summary
A wireless access point (AP) receives a certificate from an application executing on a computing device that has not connected to the wireless AP, wherein the certificate does not include a password to a service set identifier (SSID) that is broadcast by the wireless AP. The wireless AP determines that the certificate is associated with an entity that is an authorized entity. In response to determining, that the certificate is associated with the entity that is the authorized entity, the wireless AP establishes a time-limited connection with the computing device.
