Quantum-Safe Authentication

42 microseconds. Post-quantum. Production-ready.

Authentication tokens signed with RSA or ECDSA are already being harvested. Replace them with NIST post-quantum signatures — one API call, no SDK changes, no user-facing changes.

const result = await h33.verify({
  token: userToken,
  policy: "pq_auth"
})

if (result.verified) {
  // User authenticated with PQ signature
  // result.proof = H33-74 attestation
}

No crypto expertise required · No infrastructure changes · No engine selection

Why Auth Is the First Thing to Migrate

✓Auth tokens have the highest harvest-now-decrypt-later exposure
✓Session keys protect everything downstream — compromise here = total access
✓Auth is a well-defined surface — easier to migrate than full stack
✓Users don't see the change — no UX impact, no retraining
✓Budget is already allocated — auth is a line item, not a new category

What Changes

✓Token signing: RSA/ECDSA → ML-DSA (FIPS 204)
✓Key exchange: ECDH → ML-KEM (FIPS 203) for session establishment
✓Verification: H33 returns PQ-signed proof with every auth
✓Nothing else: your login flow, OAuth, JWT structure all stay the same
✓Optional: FHE biometric matching — 35.25µs, zero plaintext exposure

Performance

✓42µs per authentication — faster than most classical implementations
✓1,667,875 auth/sec sustained on Graviton4 hardware
✓Batch processing: 32 users per ciphertext (SIMD)
✓Three independent PQ signature families per attestation
✓Zero plaintext exposure at any stage — data encrypted end-to-end

Full NIST FIPS 203/204 compliance. FHE biometric matching available. SOC 2 Type II in progress.
