H33 — Post-Quantum Cryptography Platform
Overview
H33 provides fully homomorphic encryption, zero-knowledge proofs, post-quantum
signatures, and encrypted biometric authentication through a single API. All
computation runs on encrypted data — plaintext is never exposed server-side.
Products
H33-128 — 128-bit BFV fully homomorphic encryption. ~42µs per authentication,
1,595,071 auths/sec on production hardware. 32 users per ciphertext via SIMD
batching.
H33-256 — 256-bit NIST Level 5 FHE for government and defense. BFV with
N=32768, ML-DSA-87 attestation.
H33-CKKS — Approximate arithmetic FHE for ML inference, encrypted dot
products, and cosine similarity on ciphertexts.
FHE-IQ — Intelligent routing layer that automatically selects the optimal FHE
backend (BFV-64, CKKS, BFV-32) per workload. Sub-500ns routing decisions.
H33-3-Key — Nested triple post-quantum signatures: Ed25519 + Dilithium-5
(ML-DSA-87) + FALCON-512. Three mathematical families, survives any single
algorithm break.
ZKP — STARK lookup proofs with SHA3-256 hashing and FRI polynomial
commitments. Post-quantum secure proof generation and verification.
Encrypted Biometrics — Biometric matching runs entirely on ciphertexts using
FHE. Templates are encrypted client-side and never decrypted server-side.
