Technical Summary

   This document defines Post-Quantum Traditional (PQ/T) Hybrid key
   exchange methods based on the quantum-resistant the Module-Lattice-
   Based Key-Encapsulation Mechanism (ML-KEM) standard and traditional
   Elliptic-curve Diffie–Hellman (ECDH) key exchange schemes.  These
   methods are defined for use in the SSH Transport Layer Protocol.

Working Group Summary

   There was heated discussion around both this draft and 
   draft-ietf-sshm-ntruprime-ssh (currently in the editor's queue).  The 
   working group consensus is that both specifications will  be the same 
   when it comes to the IANA recommendation for implementers (that they 
   SHOULD be implemented) and the type of RFC desired (Informational).
   See the shepherd's writeup for more detail.

Document Quality

  Implementations exist, they are noted on the mailing list.

Personnel

   The Document Shepherd for this document is Stephen Farrell. The
   Responsible Area Director is Deb Cooley.
