FALCON-512 Attestation | HICS-PQ

FALCON 512

Post-quantum digital signature attestation. NTRU lattice-based. Compact signatures — independent lattice family from Dilithium for defense-in-depth.

The algorithm is the authority. H33 does not editorialize scores.

This page is a HICS attestation — HICS scores H33's implementation of FALCON. FALCON and NIST FIPS 206 are referenced here, not owned; the portable evidence these signatures produce belongs to H33-74. Not a new product.
