Research paper: Post-quantum traditional (PQ/T) hybrid key agreement mechanisms for TLS 1.3

Abstract: This document defines three hybrid key agreement mechanisms for TLS 1.3 — X25519MLKEM768, SecP256r1MLKEM768, and SecP384r1MLKEM1024 — that combine the post-quantum ML-KEM (Module-Lattice-Based Key Encapsulation Mechanism) with an ECDHE (Ephemeral Elliptic Curve Diffie-Hellman) exchange.
