Wireless Frame Integrity Verification for Multi-Link Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack robust integrity protection mechanisms, particularly in multi-link operations, which can compromise the security and integrity of wireless transmissions.
Innovation Solution
Implementing integrity protection (IP) capabilities through parameter field adjustments and checksum calculations for downlink and uplink frames, including Header Message Integrity Check (MIC) fields and Frame Number (FN) fields, to verify correct frame reception and ensure secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrity protection mechanisms are implemented in wireless transmissions, then security and integrity of wireless transmissions are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies parameter changes by adjusting specific fields within existing frame structures (such as modifying the FC field, TD field, or adding integrity protection fields) to enable integrity verification without fundamentally changing the overall communication protocol architecture. This allows integrity protection to be implemented by changing parameters of existing structures rather than introducing entirely new complex mechanisms.
Solution Approach 2:
The integrity protection mechanism is segmented into distinct components: frame generation with integrity fields, transmission of these structured frames, and separate verification processes at the receiving end. This segmentation allows each component to be optimized independently and simplifies the overall implementation complexity while maintaining reliable integrity protection.
2Measurement precision
If parameter field adjustments and checksum calculations are performed for each frame, then verification of correct frame reception is improved, but processing time and computational overhead increase
Solution Approach 1:
The patent implements preliminary action by pre-calculating and embedding integrity protection values (such as checksums or MIC fields) into frame structures during the frame generation phase at the transmitting end. This preliminary computation allows the receiving end to perform only simple verification operations rather than complex calculations, significantly reducing verification time while maintaining high accuracy.
3Object-affected harmful factors
If Header MIC fields and Frame Number fields are used for integrity verification, then security against unauthorized access is improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent applies universality by designing the integrity protection mechanism to work across multiple frame types and communication scenarios using a unified approach. The same basic principles of embedding MIC fields and Frame Number fields are applied universally to different frame structures (data frames, control frames, etc.), allowing a single implementation framework to provide security across diverse wireless communication situations without requiring separate complex mechanisms for each case.

AI summary
Methods, systems and apparatuses for performing enhanced integrity protection techniques by an access point (AP) and non-AP are described. A station (STA) can receive, from an access point (AP), an integrity protection (IP) capability request and transmit an IP capability response to the AP. The STA can receive, from the AP, one or more downlink (DL) frames comprising at least one adjusted parameter field of a plurality of parameter fields. The STA can verify, based on at least one value of the adjusted parameter field or one or more parameter fields of the plurality of parameter fields, that the one or more DL frames have been correctly received from the AP.
