GenerateRandom (from an enclave)

The following example shows an Amazon CloudTrail log entry for a kms-generate-random operation in the Nitro Enclaves SDK. The kms-generate-random API calls the Amazon KMS GenerateRandom operation with a parameter that includes a signed attestation document from the enclave.

Amazon Nitro Enclaves is an Amazon EC2 capability that lets you create isolated compute environments called enclaves to protect and process highly sensitive data. For more information about Amazon Nitro Enclaves and its integration with Amazon KMS, see Nitro Enclaves in the Amazon EC2 User Guide for Linux Instances.

When the call originates in an enclave, the CloudTrail log includes recipient data that represents the measurements of the enclave.
