NVIDIA Confidential Computing Attestation for Next-Generation AI Hardware - Rob Nertney & Spencer Gilson, NVIDIA
NVIDIA's attestation infrastructure was born from Confidential Computing - securing Hopper GPUs with hardware-rooted, in-band attestation. As AI hardware evolves to rack-scale systems like Vera Rubin NVL72, attestation must evolve with it: new devices, new modes, and new challenges.
This talk covers three dimensions of that evolution. First, we discuss how CC attestation scales to rack-level with Vera Rubin, including NVIDIA's multi-node solution for CC and the challenge of attesting dozens of GPUs, CPUs, and NVSwitches as a unified trusted system. Second, we show how attestation patterns proven in CC are extending to new modes and device types - including fleet intelligence and out-of-band attestation. Third, we share the standards and interoperability challenges we have encountered along the way: inconsistent implementations across the ecosystem, gaps in attestation policy standards, and binding discrete components into trusted subsystems to prevent relay and substitution attacks.
Attendees will leave understanding where NVIDIA attestation is heading and what we have learned about the open problems the ecosystem must solve together.
