Speed Comparison

H33 vs Microsoft SEAL

Same security. Different speed. 5-7x faster on core FHE operations, 118x faster on compute-heavy operations.

Same Security, Different Speed

Operation SEAL BFV H33 Q-128 H33 Advantage
Encrypt 500-800 µs 506 µs Comparable
Square/Multiply 4,720 µs ~40 µs 118x faster
Relinearize 11,900 µs n/a (no relin) ∞ (skipped)
Full Auth Pipeline ~6,000 µs 866 µs 5-7x faster

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.

~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.

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

128-bit minimum required for compliance.

Many vendors use ~100-bit for speed. They'll fail your audit.

H33 Default:

128-bit, NIST Level 1, FIPS 203/204 ✓

H33 Q-Dev (opt-in):

~100-bit, 372µs, for ephemeral/gaming/dev
