Sub-Millisecond Security:
Real-Time Authentication Without Compromise

For decades, security and speed were trade-offs. Want stronger cryptography? Accept more latency. Need real-time performance? Compromise on protection. H33 breaks this trade-off, delivering military-grade security in microseconds.

What Happens in 1.28 Milliseconds

H33's Full Stack Auth (Turbo mode) completes in 1.28ms. Here's what happens in that time:

Security Properties Maintained

Speed doesn't mean shortcuts. Every H33 authentication includes:

• Zero-knowledge proofs: Prove identity without revealing biometrics
• FHE protection: Biometric templates never decrypted on server
• Post-quantum signatures: Dilithium3 (NIST FIPS 204 compliant)
• Perfect forward secrecy: Session keys derived per-authentication
• Replay protection: Nonces and timestamps prevent replay attacks

Why This Matters for Real-Time Applications

Gaming: In competitive gaming, 100ms of latency is the difference between winning and losing. Authentication can't add to that budget. At 1.28ms, H33 adds less than 0.3ms—imperceptible.

Trading: High-frequency trading systems measure in microseconds. Session resume at 50µs fits within the tightest latency budgets.

Healthcare: Emergency room systems need instant access. Sub-millisecond authentication means no delay when seconds matter.

IoT: Constrained devices with limited power can't afford expensive cryptographic operations. H33's efficiency means security without battery drain.

The Technology Behind It

Achieving sub-millisecond security required fundamental innovations:

• Native Rust core: Critical cryptographic paths bypass JavaScript entirely
• Custom ZK circuits: Circuits optimized specifically for authentication
• SIMD acceleration: AVX-512 vectorization for parallel proof generation
• Smart caching: 67x speedup on repeated operations
• Incremental verification: Only verify what changed

Comparing to Alternatives

Traditional authentication latencies for comparison:

• OAuth token validation: 5-50ms (network dependent)
• LDAP authentication: 10-100ms
• SAML assertion: 50-500ms
• WebAuthn/FIDO2: 100-300ms (hardware dependent)
• H33 Full Auth: 0.22ms

H33 is 20-1000x faster than traditional alternatives while providing stronger security guarantees.
