Speed Comparison

H33 vs Microsoft SEAL

Same security. Complete pipeline. ~11x faster. Zero data exposure. k-of-n threshold means no single server sees your plaintext.

Same Security, Different Speed

Operation SEAL BFV H33 H33 H33 Advantage
Encrypt 500-800 µs 965µs Comparable (H33 includes encoding)
Compute Distance 4,720 µs 199µs 24x faster
Relinearize 11,900 µs n/a (no relin) ∞ (skipped)
Full Auth Pipeline ~17,920µs 2,648µs ~11x faster + zero exposure

Why the difference? SEAL is a general-purpose FHE library. H33 is purpose-built for authentication: shallow circuits, aggressive batching, no relinearization needed. Same BFV scheme, same security—just optimized for one use case.

Why Quantum Computing Changes Everything

Your current encryption (RSA-2048, ECDSA):

Classical Computer
300 trillion years to break
Quantum (4,000 qubits)
~10 seconds

Shor's algorithm breaks every RSA key, every ECDSA signature, every TLS handshake.

"Harvest Now, Decrypt Later"

Nation-states are recording encrypted traffic TODAY. When quantum arrives, they decrypt everything retroactively.

  • Your 2024 trade secrets
  • Your 2025 M&A communications
  • All exposed.

Timeline

2024: NIST finalizes post-quantum standards ✓
2025-2026: Federal transition mandates begin
2028-2032: Cryptographically relevant quantum expected
2030+: Everything encrypted before transition = compromised

NIST Post-Quantum Cryptography Standards

NIST (National Institute of Standards and Technology) sets cryptographic standards for U.S. government and enterprise.

August 2024 Standards:

FIPS 203ML-KEM (Kyber)Key Exchange
FIPS 204ML-DSA (Dilithium)Signatures
FIPS 202SHA-3Hash Functions

Three NIST-Compliant Tiers ✓

H2 & H33 (N=4096) → 128-bit NIST L1. bfv_params_override ensures Q ≤ HE Standard max.
H-256 (N=16,384) → 256-bit NIST L5. Q=216 bits within HE Standard max of 237 bits.

H0: Non-NIST Dev Tier

H0 (N=1024) dev only (~57-bit). Turbo Full Match: 212µs. No threshold, no PLOOKUP, no Dilithium.

H33/H-256 Zero Exposure:

Biometric NEVER decrypted on any single server. k-of-n threshold decrypt. Dilithium3/Kyber768 = NIST Level 3.
