Hi Panos,
Hi draft-ietf-ipsecme-ikev2-multiple-ke authors, ipsecme WG, We have seen attempts to get early codepoints allocated for PQ-hybrid key exchanges in TLS 1.3 and HPKE in other IETF WGs. These, I think, are are good steps. Note for these IANA registries the requirement is "Specification Required". How about new PQ Transform Type 4 identifiers in IKEv2? Currently the draft-ietf-ipsecme-ikev2-multiple-ke draft says It is assumed that new Transform Type 4 identifiers will be assigned later for various post-quantum key exchanges [ <https://datatracker.ietf.org/doc/html/draft-ietf-ipsecme-ikev2-multiple-ke-12> IKEV2TYPE4ID]. So, if draft-ietf-ipsecme-ikev2-multiple-ke will not assign new identifiers for Kyber-768 in <https://www.iana.org/assignments/ikev2-parameters/ikev2-parameters.xhtml#ikev2-parameters-8> https://www.iana.org/assignments/ikev2-parameters/ikev2-parameters.xhtml#ikev2-parameters-8, should we be asking the Experts (Tero, Valery) consider a new allocation? Yes, that's correct. However, while it is possible to ask IANA for new allocation without any referencing document, as designated expert I would be much more comfortable if some document (even I-D) exists describing how to use Kyber-768 in specific environment of IKEv2. This may be a very short document referencing generic Kyber specification and clarifying implementation details for IKEv2 (e.g. the format of the public key etc.). Regards, Valery. Thx, Panos
