在以下示例中，运行 Amazon EC2 实例的 IAM 委托人创建并挂载使用 KMS 密钥加密的数据卷。此操作会生成多条 CloudTrail 日志记录。
创建卷后，代表客户行事的 Amazon EC2 会从 AWS KMS (GenerateDataKeyWithoutPlaintext) 获得加密的数据密钥。然后会创建一个授权 (CreateGrant)，从而允许它解密数据密钥。装入卷后，Amazon 会 EC2 调 AWS KMS 用解密数据密钥 () Decrypt。
Amazon EC2 实例的"i-81e2f56c"，出现在RunInstances事件中。instanceId使用相同的实例 ID 来限定所创建授权的 granteePrincipal ("111122223333:aws:ec2-infrastructure:i-81e2f56c") 以及 Decrypt 调用中的委托人的代入角色 ("arn:aws:sts::111122223333:assumed-role/aws:ec2-infrastructure/i-81e2f56c")。
用于保护数据量的 KMS 密钥的密钥 ARN 出现在所有三个 AWS KMS 调用中（CreateGrantGenerateDataKeyWithoutPlaintext、和Decrypt）。arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
