# Hardware-Rooted AI Security That Won’t Slow You Down

**[NVIDIA Developer](https://daily.dev/sources/nvidiadev)** · 6 min read · 0 upvotes · 0 comments

## Summary

NVIDIA Confidential Computing (CC) secures AI inference workloads at the hardware level using Blackwell GPUs with a silicon-embedded private key, remote attestation via NRAS (supporting AMD SEV-SNP and Intel TDX), and encrypted NVLink interconnects. Benchmarks on HGX B300 running Qwen 3.5 397B at FP8 precision show CC adds only 2–8% overhead across throughput and time-per-output-token metrics at various concurrency levels. Performance optimizations include CC-safe autotuner timing in FlashInfer, async device-to-host copy workers in SGLang, and piecewise CUDA graph support to reduce kernel launch overhead amplified in CC mode.
