[STDS-802-11-TGBE] CID 13599 - Replay detection for CCMP and GCMP

[M Montemurro <montemurro.michael@xxxxxxxxx>]

Hello all, 

During the discussion of https://mentor.ieee.org/802.11/dcn/22/11-22-1178-03-00be-tgbe-lb266-security-comment-resolutions.docx, we did not reach a conclusion of CID 13599.  I'd like to initiate a discussion on the reflector to see if there is consensus on a resolution to this CID.

The comment references text in the base standard that describes PN processing based on the PN value and the TA value. However for both GCMP and CCMP in the baseline, the TA is missing from the block diagram as input to the Replay Check block. 

I think that the proper way to specify the MLO behavior is to fix the baseline and then add the MLO behavior. However in absence of that, I provided text changes (see document above) that describe the behavior consistent with what's currently in the baseline. 

Please provide input.

Thanks,

Mike
