Amazon EC2 示例二
在以下示例中，运行 Amazon EC2 实例的 IAM 主体会创建并挂载一个使用 KMS 密钥加密的数据卷。此操作会生成多个 CloudTrail 日志记录。有关 Amazon EBS 和加密的更多信息，请参阅 Requirements for Amazon EBS encryption。
创建卷时，Amazon EC2 将代表客户从 Amazon KMS (GenerateDataKeyWithoutPlaintext) 获取加密的数据密钥。然后会创建一个授权 (CreateGrant)，从而允许它解密数据密钥。装载卷时，Amazon EC2 会调用 Amazon KMS 来解密数据密钥 (Decrypt)。
Amazon EC2 实例的 instanceId、"i-81e2f56c" 将出现在 RunInstances 事件中。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")。
保护数据卷的 KMS 密钥的密钥 ARN、arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab 将出现在全部三个 Amazon KMS 调用（CreateGrant、GenerateDataKeyWithoutPlaintext 和 Decrypt）中。
