Trust & Security Center

OAIS Sentinel is built on a non-custodial, zero-knowledge security architecture engineered specifically for regulated financial institutions, healthcare systems, and enterprise AI workloads.

🔒 Zero-Knowledge Sovereign Architecture

Raw prompt payloads and model completions are NEVER transmitted or stored in plaintext on OAIS infrastructure.

Client-side HMAC-SHA256 privacy salting
Non-custodial private key vaulting
Mathematical zero-knowledge audit receipts

📄 Immutable RFC 6962 Merkle Ledger

Every inference event produces a cryptographically sealed, tamper-evident audit leaf verifiable from first principles.

JCS RFC 8785 canonical JSON serialization
Ed25519 digital signatures & RFC 3161 timestamps
First-principles logarithmic Merkle inclusion proofs

👑 Hardware Attestation (Nitro Enclaves)

Cryptographic ledger processing executes within hardware-isolated AWS Nitro Enclaves with validated PCR measurements.

No persistent storage, no interactive shell access
Cryptographic PCR0/PCR1/PCR2 measurement certificates
Hardware-backed cryptographic signing keys

📡 Regulatory Compliance Alignment

Turnkey compliance evidence generation engineered for the strictest regulatory jurisdictions globally.
