Abstract:

   This document specifies the PQ-SecChannel cryptographic protocol,
   which defines a secure interactive channel consisting of a Transport
   Authentication Protocol and a Connection Protocol.  The protocol is
   designed to provide confidentiality, integrity, and mutual
   authentication in the presence of quantum computing threats.  PQ-
   SecChannel incorporates standardized post-quantum cryptographic
   algorithms, including lattice-based KEMs and signatures (e.g., Kyber
   and Dilithium), Chinese post-quantum candidate algorithms (e.g.,
   Aigis), and code-based KEMs (e.g., HQC), together with SM4-GCM for
   AEAD (Authenticated Encryption with Associated Data) and SM3 for
   hashing and key derivation.  This specification is derived from the
   Chinese national cryptography standard draft "PQ-SecChannel
   Cryptographic Protocol Specification", adapted into IETF Internet-
   Draft style for international review and potential interoperability
   consideration.  The protocol content also references the Secure Shell
   architecture ([RFC4251], [RFC4252], [RFC4253], and [RFC4254]) and the
   Chinese SSH cryptographic protocol specification [GMT0129].
