These combinations are tailored to meet security best practices and regulatory requirements. Composite ML-DSA is applicable in any application that uses X.509, PKIX, and CMS data structures and protocols that accept ML-DSA, but where the operator wants extra protection against breaks or catastrophic bugs in ML-DSA.}, }
