加密的需求](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption-requirements.html#ebs-encryption-instance-permissions)。 建立磁碟區時，代表客戶的 Amazon EC2 會從 AWS KMS () 取得加密的資料金鑰`GenerateDataKeyWithoutPlaintext`。然後它建立一個授予權限 (`CreateGrant`)，允許它解密資料密鑰。掛載磁碟區時，Amazon EC2 會呼叫 AWS KMS 來解密資料金鑰 (`Decrypt`)。 Amazon EC2 執行個體的 `instanceId` (`"i-81e2f56c"`) 會顯示在 `RunInstances` 事件中。相同執行個體 ID 會使 `granteePrincipal` 授權限定所建立的授權 (`"111122223333:aws:ec2-infrastructure:i-81e2f56c"`) 和假設角色是 `Decrypt` 呼叫中的委託人 (`"arn:aws:sts::111122223333:assumed-role/aws:ec2-infrastructure/i-81e2f56c"`)。 保護資料磁碟區 的 KMS 金鑰金鑰 [ARN](concepts.md#key-id-key-ARN) `arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`會出現在所有三個 AWS KMS 呼叫中 (`CreateGrant`、 `GenerateDataKeyWithoutPlaintext`和 `Decrypt`)。 ``` { "Records": [ { "eventVersion":
