# Post-Quantum AI Governance Infrastructure
# https://h33.ai

H33 provides post-quantum AI governance infrastructure: governance for AI agents,
enterprise systems, and sensitive data, with cryptographic proof that survives
the original system, vendor, or signing principals.

## Five Core Products
- Agent-008 (https://h33.ai/agent-008/) — AI agent governance, drift prevention, authority preservation
- HATS (https://h33.ai/hats/) — Continuous control verification and cyber-insurance claim evidence
- H33-74 (https://h33.ai/h33-74/) — Portable 74-byte post-quantum attestation and verification footprint
- PQ Verified (https://h33.ai/pq-verified/) — Post-quantum compliance validation across systems and data
- Cryptographic APIs (https://h33.ai/post-quantum-api/) — FHE, ZK, PQ signatures, replay, attestation

## Underlying Substrate
- H33-Root (https://h33.ai/h33-root/) — Authority and intent preservation substrate
- H33-Key (https://h33.ai/h33-key/) — AI credential security and secret-use governance
- H33-Upstream (https://h33.ai/h33-upstream/) — Provenance capture at the data origin
- Agent-Zero (https://h33.ai/agent-zero/) — Encrypted AI inference (operate on data the agent never sees)
- Q-Sign (https://h33.ai/q-sign/) — Post-quantum approval governance

## Crypto Engines
- BFV / CKKS / TFHE (and 256-series at https://h33.ai/h33-256/) — FHE engines
- ML-DSA, FALCON, SLH-DSA — NIST FIPS 204/205/206 PQ signature families
- ZK-Verify, ZKP-AIR, ZK-Trustless — Zero-knowledge attestation suite

## Standards
- HATS (https://h33.ai/standard/) — Hybrid Attestation Trust Standard
- PQ-Verified (https://h33.ai/pq-verified/) — Post-quantum verification standard
- HICS, CRV, OIS, Q-Key — Open governance specifications
