Informatique confidentielle
Protection des données en cours d'utilisation.
Beyond storage (at rest) and networking (in transit), Confidential Computing encrypts memory while code is running. Using secure enclaves (Intel SGX, AMD SEV), it isolates sensitive data even from the cloud provider. Remote attestation allows users to verify hardware integrity before processing. In 2026, it is the standard for Confidential AI on H100 GPUs.

🤓 Expert Deep Dive
Three pillars: Isolation, Encryption, and Attestation. CPU-based MEE (Memory Encryption Engines) protect against physical RAM probing. Attestation quotes verified against manufacturer roots of trust ensure logic hasn't been tampered with. The focus has moved from application enclaves (SGX) to full VM isolation (TDX/SEV-SNP).
