Hi, this version addresses comments received during AD review of the draft.
Regards, Valery. > Internet-Draft draft-ietf-ipsecme-ikev2-qr-alt-07.txt is now available.

The > protection is achieved by means of Post-quantum Preshared Key (PPK) > which is mixed into the session keys calculation. However, this > protection doesn't cover an initial IKEv2 SA, which might be > unacceptable in some scenarios. This specification defines an > alternative way to get protection against quantum computers, which is > similar to the solution defined in RFC8784, but protects the initial > IKEv2 SA too. > > RFC8784 assumes that PPKs are static and thus they are only used when > an initial IKEv2 Security Association (SA) is created. If a fresh > PPK is available before the IKE SA expired, then the only way to use > it is to delete the current IKE SA and create a new one from scratch, > which is inefficient. This specification defines a way to use PPKs > in active IKEv2 SAs for creating additional IPsec SAs and rekey > operations. > > The IETF datatracker status page for this Internet-Draft is: > https://datatracker.ietf.org/doc/draft-ietf-ipsecme-ikev2-qr-alt/ > > There is also an HTMLized version available at: > https://datatracker.ietf.org/doc/html/draft-ietf-ipsecme-ikev2-qr-alt-07 > > A diff from the previous version is available at: > https://author-tools.ietf.org/iddiff?url2=draft-ietf-ipsecme-ikev2-qr-alt-07 > > Internet-Drafts are also available by rsync at: > rsync.ietf.org::internet-drafts > > > _______________________________________________ > IPsec mailing list -- ipsec@ietf.org > To unsubscribe send an email to ipsec-le...@ietf.org _______________________________________________ IPsec mailing list -- ipsec@ietf.org To unsubscribe send an email to ipsec-le...@ietf.org
