Post-quantum hybrid key exchange in SSH

Abstract

This document defines post-quantum hybrid key exchange methods based on classical ECDH key exchange and post-quantum key encapsulation schemes. These methods are defined for use in the SSH Transport Layer Protocol.

Keywords: key exchange, Secure Shell (SSH), post-quantum cryptography
