NVIDIA has detailed how its Confidential Computing (CC) technology enables secure, high-performance AI inference, particularly for large language models (LLMs) processing sensitive data. This technology uses memory-encrypted confidential virtual machines (CVMs), confidential GPUs, and encrypted NVIDIA NVLink to create a trusted execution environment.
Running inference frameworks like NVIDIA TensorRT LLM within a CC-enabled environment introduces changes to assumptions about memory movement, timing, scheduling, and multi-GPU communication. To maintain high performance, NVIDIA has optimized the inference framework and the confidential computing environment together.
Key Points
- NVIDIA Confidential Computing provides a secure environment for LLM inference using memory-encrypted CVMs, confidential GPUs, and encrypted NVIDIA NVLink.
- Inference frameworks like NVIDIA TensorRT LLM require CC-aware adaptations to account for secure execution and preserve performance.
- A controlled methodology involves comparing workload performance with CC enabled and disabled, keeping all other variables constant.
- NVIDIA performance engineering observed CC-on retained 96.1% to 98.2% of CC-off output-token throughput across concurrency 1–16.
- Mean tokens per output token (TPOT) with CC enabled remained within 1.2% to 4.3% of the baseline.
- TensorRT LLM adapts to secure data movement, autotuning, and multi-GPU communication in NVIDIA Blackwell CC configurations.
- NVIDIA Confidential Computing extends hardware-enforced protection across confidential VMs, NVIDIA Blackwell GPUs, and encrypted NVLink.
Context
According to the NVIDIA Developer Blog, as LLM inference increasingly processes sensitive information and proprietary model context, data must be processed within a trusted environment. NVIDIA Confidential Computing addresses this need by providing hardware-enforced security paths for protecting data and workloads in use.
Why It Matters
For AI platform engineers and TensorRT LLM users, the ability to run production AI inference with strong security guarantees while retaining high performance is critical. This approach allows organizations to deploy private inference for sensitive applications without significant performance compromises, treating security configuration and inference optimization as a unified deployment problem.
What To Do
- Consult the NVIDIA Trusted Computing documentation to plan confidential inference deployments.
- Explore the latest TensorRT LLM features and release notes for relevant updates.
- Benchmark CC-on and CC-off performance using your specific target workload.
- Note that high request volume can amortize fixed encryption costs, making CC overhead less visible.
