A comment about draft-songlee-aes-cmac-prf-128-00: Some features of IKEv2 work, well, poorly with PRFs that require a fixed size key (see draft-eronen-ipsec-ikev2- clarifications-03, Sections 2.8, 2.9, and 3.5 for details). Currently we have only one such PRF (AES-XCBC-PRF-128), but there's work ongoing (draft-hoffman-rfc3664bis-02) to remove the fixed key size restriction from XCBC-MAC (by specifying how to get a 128-bit key from a shorter or longer key). I think it would be useful to include such processing in CMAC-PRF as well (so from IKEv2 point of view, it would accept a key of arbitrary length). Best regards, Pasi (BTW, the draft also needs an IANA considerations section.) > -----Original Message----- > From: Russ Housley > Sent: Wednesday, June 08, 2005 6:55 PM > To: ipsec@ietf.org > Subject: [Ipsec] CMAC Documents > > Dear IPsec Mail List: > > I am going to shepherd these documents.
