The biggest difficulty in data centers and clouds is AI Compatible with different workloads, standalone, and hybrid cloud/edge deployment. Many AI activities require GPU acceleration AI is changing finance, manufacturing, advertising, and healthcare
The Intel Trust Authority Client uses the NVIDIA Attestation SDK and nonce to retrieve the GPU driver’s CPU TEE (Intel TDX CVM) attestation report
CPU, GPU TEEs from Intel and NVIDIA Confidential Computing differ To trust CPU and GPU TEEs, customers need two suppliers’ certification
Xeons with Intel TDX extensions support hardware TEEs Intel TDX isolates VMs from the VMM/hypervisor and other software outside the Trust Domain, preventing software attacks
Call the Intel Trust Authority Client for full platform attestation and receive one token or CPU and GPU attestation and two tokens Both Intel Trust Authority SaaS and NVIDIA NRAS verify CPU and GPU attestation
This Intel-NVIDIA alliance provides a uniform attestation solution for Confidential Computing CPU and GPU TEEs using Intel Xeon CPUs with Intel TDX and NVIDIA Tensor Core H100 GPUs. Xeons with Intel TDX extensions support hardware TEEs
After obtaining attestation evidence from Intel TDX and H100 GPU, the Intel Trust Authority Client connects the Intel Trust Authority SaaS, which calls NRAS for the NVIDIA signed token with demonstrated proof
Intel TDX CPU, NVIDIA H100 GPU TEEs Key brokers and distribution services must process CPU and GPU attestation information before issuing TEE keys
