Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Paul Wouters 2017-07-16 21:47:58 UTC

Implement: https://tools.ietf.org/html/draft-fluhrer-qr-ikev2-04

A quantum computer would be able to solve
   DH and ECDH problems, and this would imply that the security of
   existing IKEv2 systems would be compromised.  IKEv1 when used with
   strong preshared keys is not vulnerable to quantum attacks, because
   those keys are one of the inputs to the key derivation function.  If
   the preshared key has sufficient entropy and the PRF, encryption and
   authentication transforms are postquantum secure, then the resulting
   system is believed to be quantum resistant, that is, believed to be
   invulnerable to an attacker with a Quantum Computer.

   This document describes a way to extend IKEv2 to have a similar
   property; assuming that the two end systems share a long secret key,
   then the resulting exchange is quantum resistant.  By bringing
   postquantum security to IKEv2

Comment 2 Paul Wouters 2017-12-12 00:50:51 UTC

This currently implements draft-fluhrer-qr-ikev2, not its successor draft-ietf-ipsecme-qr-ikev2-00. It also uses private-use values since no IANA code points are available yet.

For beta2 we expect to be updated to ipsecme-qr-ikev2-00 and have Early Code points requested at IANA.

For testing, see included testing/pluto/*ppk* test cases
