4x faster than Microsoft SEAL. 100x faster than Zama. Zero licensing fees.
Fully Homomorphic Encryption promises computation on encrypted data—but existing implementations are measured in seconds, not microseconds.
Microsoft SEAL requires expensive RNS-to-BigInt conversions on every operation. Zama charges six-figure licensing fees and still can't match our speed. Neither offers bootstrapping, GPU acceleration, or the complete authentication stack modern applications demand.
H33 rewrote the math.
"We eliminated big integer operations entirely. The result is FHE that's finally fast enough for real-time authentication."
The industry standard for BFV homomorphic encryption
AWS c7i.48xlarge, AVX-512, February 2026
| Operation | Microsoft SEAL | H33-FHE | H33 Advantage |
|---|---|---|---|
| BFV Multiply (n=16k) | 180ms | 45ms | 4x faster |
| Relinearize | 90ms | 25ms | 3.6x faster |
| Key Switch | 90ms | 25ms | 3.6x faster |
| NTT (n=64k) | 3.5ms | <1ms | 3.5x faster |
| CKKS Multiply (n=16k) | 50ms | 20ms | 2.5x faster |
| Add Operations | 2ms | 1ms | 2x faster |
It's not just faster—it's architecturally superior with capabilities Microsoft SEAL simply doesn't have.
Zama charges $100K–$500K+ for patent licenses and requires $ZAMA tokens. H33 is 100x faster with zero license fees.
Verified on AWS c7i.48xlarge (192 vCPU, AVX-512)
Eliminates expensive RNS ↔ BigInt conversions using Bajard et al.'s scaling technique. All operations stay in residue number system representation.
Result: 4x faster multiply
Hand-optimized NTT kernels leveraging 512-bit SIMD operations. Optional GPU offload via CUDA and Metal compute shaders.
Result: 3.5x faster transforms
Full bootstrapping implementation enables unlimited computation depth—something SEAL cannot do at all.
Result: Unlimited multiplicative depth
Advanced key switching with optimized noise budget management. Less noise growth means more operations before refresh.
Result: 3.6x faster key operations
Security parameters tuned against latest lattice attack estimates rather than conservative defaults.
Result: Optimal security/performance balance
NIST-compliant quantum-resistant authentication in 1.75ms. 29-34x faster than Microsoft SEAL. One API call.
