The > protection is achieved by means of a Post-quantum Preshared Key (PPK) > which is mixed into the session keys calculation. However, this > protection does not cover an initial IKEv2 Security Association (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 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-08 > > A diff from the previous version is available at: > https://author-tools.ietf.org/iddiff?url2=draft-ietf-ipsecme-ikev2-qr-alt-08 > > 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
