Shows a practical stack that keeps prompts, RAG DBs and model weights encrypted while running by combining memory encryption and remote attestation on enclave hardware (Intel SGX/TDX, AMD SNP, ARM, Nvidia H100 GPU enclaves). Demonstrates two products: opaque workspace for joint analytics where two silos each encrypt with their own key and an enclave trains/aggregates without revealing raw data (customer: Accenture), and a gateway that strips PII with tokenization while preserving model accuracy. Claims inference overhead ≈5% and argues FHE is orders of magnitude slower.
