Hi Dan,

I understand it is the case today but as EPD mode is a totally “new” format for 802.11 should we try to unified as much as possible with the Ethernet format including encrypted frame format ? This was the initial sense of my question …

Hi Philippe,

The current P802.11ak_D0.06 draft version does not mention any requirement in regard to the encryption of EPD formatted frames.

I suggest we add a requirement that EPD formatted frames must be encrypted in a way compatible with IEEE 802.1AE (MACsec) as the 802.3/Ethernet frames are (notice that 802.11ad crypto mode is AES-GCM, the same crypto mode that the default Cypher Suite of 802.1AE).

While the cipher mode is the same the format of the frames and the location of the AAD passed to

AES-GCM is different. I think if it's an 802.11 frame it should be protected the way the 802.11 standard

specifies.

regards,

Dan.

If you agree I will post a contribution that could be discuss next Monday during the conf call.

Thank you
