Re: [STDS-802-11-TGBE] Discussion on CID 5360 (DCN 575r2)

Hi Gaurav, 

Thanks for initiating this discussion. Because I suggested this NOTE, I may provide the background. 

Current AAD construction rule is that only individually addressed Data frames use the MLD MAC address instead of the STA MAC address. 

If dot11MultiLinkActivated is true, for both the transmitter and intended receiver of the MPDU, either of To DS or From DS subfields in the MAC header of the MPDU is set to 1, and the MPDU is an individually addressed Data frame, then A1 is set to:
—the MLD MAC address of the intended receiver MLD of the MPDU.
—otherwise, Al is set to MPDU Address 1 field.

So, when another frame like a management frame is retransmitted on a different link, the frame is re-encrypted. The below note clarifies this. If people have a concern on the below NOTE, they have to comment on the above spec text. 

Thanks, 

Yongho

Hi,

Initiating this thread to discuss CID 5360 from DCN 575r2 which I presented today.  The discussion on the call was for the following NOTE:

NOTE – (#5360) For MLO, when an individually addressed management frame is retransmitted on another link, the encrypted data is modified on retransmission.
