Google Cloud 默认启用传输加密，以便在传输前加密请求，并使用传输层安全协议 (TLS) 保护原始数据。
将数据传输到 Google Cloud 进行存储后， Google Cloud默认会应用静态加密。为了更好地控制静态加密数据的方式，Google Cloud 客户可以使用 Cloud Key Management Service 并根据自己的政策生成、使用、轮替和销毁加密密钥。这些密钥称为客户管理的加密密钥 (CMEK)。
如果您需要更好地控制用于对Google Cloud Google Cloud项目中的静态数据进行加密的密钥，而不是 Google Cloud的默认加密提供的密钥，则 Google Cloud 服务提供了使用客户在 Cloud KMS 中管理的加密密钥来保护数据的功能。这些加密密钥称为客户管理的加密密钥 (CMEK)。

To gain more control over how data is encrypted at rest,\nGoogle Cloud customers can use [Cloud Key Management Service](/kms) to generate, use,\nrotate, and destroy encryption keys according to their own policies. These keys\nare called customer-managed encryption keys ([CMEK](/kms/docs/cmek)).\n\nFor certain control packages, Assured Workloads can deploy a CMEK\nproject alongside your [resources project](/assured-workloads/docs/key-concepts#resources)\nwhen you create an Assured Workloads folder.\n\nAs an alternative to CMEK, Google-owned and Google-managed encryption keys, provided by default,\nare [FIPS-140-2](https://csrc.nist.gov/publications/detail/fips/140/2/final)\ncompliant and are able to support most control packages in\nAssured Workloads. Customers can delete the CMEK project and rely\nsolely on Google-owned and Google-managed encryption keys. We recommend, however, that you decide whether to\nuse CMEK keys before you create your Assured Workloads folder as\ndeletion of existing in-use CMEK can result in inability to access or recover\ndata.\n\nCustomer-managed encryption keys (CMEK)\n---------------------------------------\n\nIf you need more control over the keys used to encrypt data at rest within a\nGoogle Cloud project than what Google Cloud's default encryption\nprovides, Google Cloud services offer the ability to protect data by using\nencryption keys managed by the customer within Cloud KMS. These\nencryption keys are called customer-managed encryption keys (CMEK).\n\nTo learn which aspects of the lifecycle and management of your keys that CMEK\nprovides, see [Customer-managed encryption keys (CMEK)](/kms/docs/cmek) in\nCloud KMS documentation. For a tutorial that guides you through\nmanaging keys and encrypted data using Cloud KMS, see the\n[quickstart](/kms/docs/quickstart) or\n[codelab](https://codelabs.developers.google.com/codelabs/encrypt-and-decrypt-data-with-cloud-kms).\n\nWhat's next\n-----------\n\n- Learn more about [creating a symmetrical key with Cloud KMS](/kms/docs/creating-keys)."]]
