Sensing Device Block Template Wireless Intrusion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless intrusion prevention systems face challenges in efficiently blocking unauthorized access in wireless networks, particularly due to complexities in managing different frequency bands and security technologies.
Innovation Solution
A sensing device is introduced that monitors connections between access points and stations, using a block template to create wireless communication messages that block unauthorized access. The device transmits block messages with a channel switching request command to stations identified as targets for blocking, allowing for efficient blocking without distinguishing between different frequency bands or security technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing wireless intrusion prevention systems block unauthorized access by analyzing messages and managing different frequency bands and security technologies, then blocking capability is achieved, but processing time and system complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-defining block templates that contain minimum information required for creating blocking messages. These templates are prepared in advance with essential fields (such as message type, duration, and basic structure) so that when blocking is needed, the system only needs to fill in specific parameters rather than constructing messages from scratch, significantly reducing processing time while maintaining effective blocking capability across different frequency bands and security technologies
2Reliability
If the system manages different frequency bands and security technologies separately, then blocking accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by creating a unified block template structure that can handle multiple frequency bands (2.4GHz, 5GHz, 6GHz) and various security technologies (WPA2, WPA3, etc.) through a single standardized framework. The template uses universal fields and parameters that work across different wireless standards, allowing the system to maintain blocking accuracy for diverse scenarios without requiring separate management mechanisms for each frequency band or security type, thereby reducing overall system complexity
3Reliability
If the system transmits block messages to all stations, then blocking effectiveness is improved, but impact on normal stations increases
Solution Approach 1:
The patent applies local quality by enabling the sensing device to identify and target specific stations for blocking based on their unique characteristics (such as MAC address, connection state, or behavior patterns) rather than treating all stations uniformly. The block template mechanism allows selective application of blocking messages only to stations that meet specific criteria, ensuring that blocking effectiveness is maintained for unauthorized stations while normal stations are excluded from the blocking action, thus minimizing harmful impact on legitimate users
