AWS Nitro Enclaves vs Intel TDX: Why Attestation Root Matters for Regulated Workloads
AWS Nitro Enclaves and Intel TDX offer different approaches to attestation for regulated workloads. Nitro Enclaves rely on AWS's Nitro Hypervisor, while Intel TDX utilizes the CPU's Measurement Root Key for attestation. The choice between these two can significantly impact compliance with GDPR and data privacy regulations.
- ▪AWS Nitro Enclaves generates attestation documents from the Nitro Hypervisor, which is controlled by AWS.
- ▪Intel TDX uses the CPU's Measurement Root Key for attestation, providing a more hardware-based trust model.
- ▪The performance overhead for Nitro Enclaves is 14-23%, while Intel TDX has a 3-7% overhead.
