Composite FN-DSA and LMS Digital Signature Algorithm for use in X.509 Public Key Infrastructure

Composite FN-DSA and LMS Digital Signature Algorithm for use in X.509 Public Key Infrastructure Entrust Crypto4a This document defines a composite signature scheme combining the FN- DSA (Falcon) digital signature algorithm with the Leighton-Micali Signature (LMS) scheme defined in RFC 8554. This construction is designed for use within X.509 Public Key Infrastructure (PKI) and follows the composite signature paradigm defined in [I-D.ietf-lamps-pq-composite-sigs].
