Cloud Storage는 데이터를 디스크에 쓰기 전에 서버 측에서 항상 암호화를 수행하며 이로 인한 추가 비용은 청구되지 않습니다. 이러한 표준 Cloud Storage 동작 외에도 Cloud Storage를 사용할 때 데이터를 암호화하는 다른 방법이 있습니다. 다음은 사용 가능한 암호화 옵션을 요약한 것입니다.
서버 측 암호화: Cloud Storage가 데이터를 수신한 후 데이터를 디스크에 기록하여 저장하기 전에 수행되는 암호화입니다.

Besides this\n[standard, Cloud Storage behavior](/storage/docs/encryption/default-keys), there are additional ways to\nencrypt your data when using Cloud Storage. Below is a summary of the\nencryption options available to you:\n\n*Server-side encryption*: Encryption that occurs after Cloud Storage\nreceives your data, but before the data is written to disk and stored.\n\n- [*Customer-managed encryption keys* (CMEK)](/storage/docs/encryption/customer-managed-keys): You can create and manage\n your encryption keys through [Cloud Key Management Service](/security-key-management). CMEK can be stored as\n software keys, in an [HSM cluster](/kms/docs/hsm), or [externally](/kms/docs/ekm).\n\n- [*Customer-supplied encryption keys* (CSEK)](/storage/docs/encryption/customer-supplied-keys): You can create and manage\n your own encryption keys. These keys act as an additional encryption layer on\n top of the standard Cloud Storage encryption.\n\n[*Client-side encryption*](/storage/docs/encryption/client-side-keys): Encryption that occurs before data is sent to\nCloud Storage. Such data arrives at Cloud Storage already\nencrypted but also undergoes server-side encryption.\n| **Warning:** If you use customer-supplied encryption keys or client-side encryption, you must securely manage your keys and ensure that they are not lost. If you lose your keys, you are no longer able to read your data, and you continue to be charged for storage of your objects until you delete them.\n\nComparing encryption options\n----------------------------"]]
