Abstract:

   This document defines combinations of US NIST Module-Lattice-Based
   Digital Signature Algorithm (ML-DSA) in hybrid with traditional
   algorithms RSASSA-PKCS1-v1.5, RSASSA-PSS, ECDSA, Ed25519, and Ed448.
   These combinations are tailored to meet regulatory guidelines in
   certain regions.  Composite ML-DSA is applicable in applications that
   use X.509 or PKIX data structures that accept ML-DSA, but where the
   operator wants extra protection against breaks or catastrophic bugs
   in ML-DSA, and where existential unforgeability (EUF-CMA) level
   security is acceptable.
