As part of reviewing work on an extension (draft-ietf-emu-aka-pfs) of EAP AKA’ (RFC 9048), the IESG has suggested that it would be better if these protocols were on the standards track. EAP AKA’ in particular is widely implemented.

The plan is to make a four-week IETF last call of RFC 9048 to change its status, but not its contents. This is what this last call announcement is about.

Separately, draft-ietf-emu-aka-pfs will also go through another IETF last call (a two week one), after other updates suggested in the IESG review are folded in the draft.

You can follow the discussion about the status and other changes in the IESG review on the working group mailing list, see [1] and [2].
