- Amazon EC2 instance attestation uses NitroTPM and Attestable AMIs to cryptographically verify trusted software and boot processes.
- Steps include building an Attestable AMI, launching a Nitro-TPM enabled instance, and comparing measurements from the Attestation Document.
- AWS KMS can validate Attestation Documents, allowing key access only if measurements match reference measurements.
- Attestation ensures only instances with trusted software can perform cryptographic operations using KMS keys.
- EC2 instances can be configured as isolated compute environments, with attestation proving isolation to third parties.
- The AWS shared responsibility model applies, with users responsible for configuring AMIs to meet their use cases.
