What is H33?

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.
