Dynamic Wireless Link Security Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network security mechanisms, such as WPA2, apply unnecessary encryption over already secure communication channels, leading to bandwidth and processing power inefficiencies, especially when transmitting many web objects that require independent acknowledgments, and complicate access control setups.
Innovation Solution
A system that dynamically selects wireless communication channels based on required security levels, allowing for unencrypted channels with access control when the content is already encrypted, thereby reducing overhead and ensuring security through endpoint encryption and rolling MAC addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If link encryption is applied to provide access control and content security, then security level is improved, but bandwidth and processing power are consumed
Solution Approach 1:
The patent implements dynamic security channels that automatically adjust encryption levels based on real-time assessment of data sensitivity and threat levels. The system transitions between encrypted and unencrypted channels dynamically, optimizing bandwidth utilization while maintaining appropriate security posture for each communication context.
Solution Approach 2:
The patent applies encryption selectively to specific data packets based on their sensitivity classification rather than uniformly encrypting all traffic. Sensitive data packets receive encryption while non-sensitive packets traverse unencrypted channels, creating local quality differentiation in security application.
2Reliability
If link encryption is applied to provide access control and content security, then security level is improved, but processing power is consumed
Solution Approach 1:
The system dynamically adjusts processing intensity by switching between encrypted and unencrypted channels based on data sensitivity. When data is classified as non-sensitive, no encryption processing is performed, eliminating unnecessary computational overhead and energy consumption.
Solution Approach 2:
The patent applies encryption only to the extent necessary for protecting sensitive data packets, rather than applying full encryption to all traffic. This partial action approach reduces processing power consumption by excluding non-sensitive data from encryption operations.
3Reliability
If MAC address filtering is used for access control, then access control is provided, but setup and maintenance complexity increases
Solution Approach 1:
The patent extracts access control functionality from the data plane and relocates it to the control plane through dynamic channel selection. Access control decisions are made based on data sensitivity classification rather than pre-configured MAC address filters, simplifying setup and maintenance while maintaining security.

AI summary
Dynamic wireless link security can be used to connect a wireless computing device to a wireless network. A determination is made as to the minimum level of security required and a wireless communication channel corresponding to that level of security is selected from among multiple, available wireless communication channels with varying levels of security. At least one of the wireless communication channels is an unencrypted channel with access control, which can be used when information is already encrypted or when encryption is not needed due to low sensitivity of the information. The determination can be made with user input or by inspecting metadata in content to be sent over the wireless link.
