Card-Based Wireless Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network authentication mechanisms are complex, network-dependent, device-dependent, and environment-dependent, leading to increased workload and security threats such as eavesdropping and data integrity issues.
Innovation Solution
A network-independent, device-independent, and environment-independent authentication system using a card and card reader that facilitates secure authentication between an end-user device and a wireless access device by reading data from the card and performing authentication protocols, including the use of hash functions and dynamic SSIDs to establish secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive authentication mechanisms (e.g., 802.1X, PKMv2) are adopted to protect wireless network security, then security threats are reduced, but operation complexity and user workload increase significantly
Solution Approach 1:
The patent introduces a card and card reader as an intermediary authentication device that bridges the user and the wireless network. The card reader, coupled to the wireless access device, reads authentication data from the card and transmits it to the access device, eliminating the need for users to manually configure complex authentication parameters while maintaining security through standardized protocols
Solution Approach 2:
The authentication system enables self-service by allowing users to simply present their card to the card reader for automatic authentication. The system automatically reads the card data, performs authentication protocols with the wireless access device, and grants network access without requiring user intervention in the authentication process itself
2Adaptability or versatility
If network-specific, device-specific, and environment-specific authentication methods are used according to standard specifications, then authentication compatibility is improved, but system adaptability across different networks and devices decreases
Solution Approach 1:
The patent creates a universal authentication system where a single card and card reader combination can authenticate across different wireless networks (WiFi, WiMAX, Bluetooth, 3G) and various end-user devices. The card reader is designed to work with multiple wireless access devices and protocols, making the authentication method independent of specific network, device, or environment configurations
Data Source
AI summary
An authentication system for a wireless network is disclosed. The authentication system includes a card, a card reader, an end-user device, and a wireless access device. The card reader is coupled to the wireless access device. The card records a data, and the card reader reads the data recorded in the card. The wireless access device receives the data read by the card reader and performs authentication between the wireless access device and the end-user device according to the data.
