Hi Adrian, Thank you for your mail. Plx see me responses below. /Philippe From: Stephens, Adrian P [mailto:Adrian.P.Stephens@xxxxxxxxx]
Hello Philippe. Do any of the existing 802.11 mechanisms (key management and encryption) unaltered meet the requirement of being “compatible with MACsec”. pk> I do not know for sure and this is why I post my mail … Also, passive voice is considered dangerous. Does “must be encrypted” mean “the 802.11 MAC shall encrypt”? pk> sorry for the wording. I meant if the frame is encrypted, the frame shall be encrypted in a format compatible with 802.1AE. pk> In other words, as EDP is unifying the 11.ak link with its wired Ethernet counterpart, we should probably guaranty that a frame transmitted over a 802.11 link in EDP format could be authenticated
with the same mechanism used for the frame transmitted over a wired link… Best Regards, Adrian P STEPHENS Tel: +44 (1793) 404825 (office) ---------------------------------------------- From: Philippe Klein [mailto:philippe@xxxxxxxxxxxx]
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). If you agree I will post a contribution that could be discuss next Monday during the conf call. Thank you /Philippe Philippe Klein, PhD |Technical Director, Broadband Technology Group Broadcom Corporation
