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
