Wireless ACK Response Framing for Secure Action Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing BAR/BA procedure in wireless communication is vulnerable to attacks due to unprotected frames, leading to security issues and performance degradation when replaced with secured frames that require longer wait times for response action frames.
Innovation Solution
Implementing a method and apparatus that generate and send an acknowledgement (ACK) control frame or a time-constrained response action frame to address the negotiation procedure, eliminating the need for additional waiting periods and enhancing security by using protected action frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secured action frames are used to replace unprotected BAR/BA frames, then security is improved, but response time increases and performance degrades
Solution Approach 1:
The patent segments the response mechanism into two types: immediate ACK control frames for rapid acknowledgment and secured action frames for detailed negotiation. This segmentation allows the system to achieve both security (through secured frames) and fast response (through immediate ACK frames), resolving the contradiction between security and response time.
Solution Approach 2:
The patent implements preliminary action by sending an immediate ACK control frame before the full secured action frame exchange. This preliminary acknowledgment confirms receipt of the request frame promptly, while the subsequent secured action frames complete the negotiation process, thus reducing the perceived response time while maintaining security.
2Reliability
If secured action frames are used instead of control frames, then security is enhanced, but transmission efficiency decreases due to longer waiting periods
Solution Approach 1:
The patent divides the response into two segments: an immediate ACK control frame that provides rapid feedback and a secured action frame that completes the negotiation. This segmentation maintains transmission efficiency by providing immediate acknowledgment while ensuring security through the protected action frame exchange.
Solution Approach 2:
The patent ensures continuity of useful action by implementing an unbroken sequence: the originator sends a request frame, the recipient immediately responds with an ACK control frame, and then exchanges secured action frames. This continuous flow prevents transmission halts and maintains high productivity while preserving security.
3Reliability
If the recipient waits for a long period to send the response action frame, then security is improved, but ongoing traffic is halted causing performance degradation
Solution Approach 1:
The patent applies preliminary action by having the recipient send an immediate ACK control frame as soon as it receives the request frame, before initiating the secured action frame exchange. This preliminary acknowledgment confirms receipt and allows the originator to continue transmission without waiting for the full negotiation, thus preventing traffic halts while maintaining security.
Solution Approach 2:
The patent ensures continuous useful action by implementing an immediate ACK response mechanism that keeps the communication flow uninterrupted. The originator receives prompt acknowledgment and can continue sending data frames while the secured negotiation proceeds in the background, preventing performance degradation while maintaining security.

AI summary
One wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame that is configured to serve as a response action frame for the request action frame, wherein the response action frame is not solicited by the request action frame. Another wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame and a time-constrained response action frame following the ACK control frame, wherein the time-constrained response action frame is solicited by the request action frame.
