Security
Post-quantum. End-to-end. Inside your boundary.
EFUPAL adopts NIST-standardized post-quantum algorithms across every cryptographic surface — with hybrid fallbacks for transition periods and full air-gap operation for classified environments.
Defense-in-depth security layers
Each layer of the stack is independently hardened, from key exchange and storage encryption through node attestation and the immutable audit chain.
Key Material
PQC keys rotate on schedule; fingerprints only in UI, raw key material never leaves the HSM boundary.
Handshakes
Every intelligence-bus channel and control-plane call uses PQC KEMs with real-time latency and failure telemetry.
At-Rest Encryption
Model weights, embeddings and prompt vaults encrypted per-volume with PQC-derived data keys.
Certificate Chain
Hierarchical PQC certificate authority scoped to your organization — no external roots of trust required.
Air-Gap Mode
No external CDN, no telemetry, no phone-home. Offline license tokens validate cryptographically.
Audit Chain
Every mutation appended to a hash-chained log; regulators can verify end-to-end integrity.
