Which Cloud Services Can Use KMS for Encryption?

Object Storage Service (OBS)

You can upload objects to and download them from OBS in common mode or server-side encryption mode. When you upload objects in encryption mode, data is encrypted at the server side and then securely stored on OBS in ciphertext. When you download encrypted objects, the data in ciphertext is decrypted at the server side and then provided to you in plaintext. OBS supports the server-side encryption with KMS-managed keys (SSE-KMS). In this mode, OBS uses the keys provided by KMS for server-side encryption.

Encrypting Data in OBS

Elastic Volume Service (EVS)

If you enable the encryption function when creating an EVS disk, the disk will be encrypted with the DEK generated by using your CMK. Data stored in the EVS disk will be automatically encrypted.

Encrypting Data in EVS

Image Management Service (IMS)

When creating a private image using an external image file, you can enable the private image encryption function and select a CMK provided by KMS to encrypt the image.

Encrypting Data in IMS

Scalable File Service (SFS)

When creating a file system on SFS, the CMK provided by KMS can be selected to encrypt the file system, so that files stored in the file system are automatically encrypted.

File System Encryption

Relational Database Service (RDS)

When purchasing a database instance, you can enable the disk encryption function of the database instance and select a CMK created on KMS to encrypt the disk of the database instance. Enabling the disk encryption function will enhance data security.

Encrypting an RDS DB Instance

Document Database Service (DDS)

When purchasing a DDS instance, you can enable the disk encryption function of the instance and select a CMK created on KMS to encrypt the disk of the instance. Enabling the disk encryption function will enhance data security.

Encrypting a DDS DB Instance

Elastic Cloud Server (ECS)

ECS uses image encryption or data disk encryption to encrypt ECS resources.

• When creating an ECS, if you select an encrypted image, the system disk of the created ECS automatically has encryption enabled, with its encryption mode same as the image encryption mode. For details about image encryption, see Encrypting Data in IMS.
• When creating an ECS, you can encrypt added data disks.

  For details about data disk encryption, see Encrypting Data in IMS.

Encrypting Data in ECS

Scalable File Service Turbo (SFS Turbo)

When creating an SFS Turbo file system, use the key provided by KMS to encrypt the file system for core data security.

Dedicated Host (DeH)

User encryption allows you to use the encryption feature provided on the cloud platform to encrypt ECS resources, improving data security. User encryption includes image encryption and EVS disk encryption.

Data Protection

FunctionGraph

To decrypt sensitive data, such as database passwords and API keys, during function runtime, you can use the KMS SDK to dynamically operate keys. You can host encryption and decryption keys in KMS and create an agency in IAM for FunctionGraph to access KMS.

Asset Identification and Management

Volume Backup Service (VBS)

EVS backup encryption feature relies on KMS. If it is encrypted, its backup data will be stored in encrypted mode.

Creating a VBS Backup

Cloud Container Engine (CCE)

You can use KMS keys to perform envelope encryption on Kubernetes Secret objects stored in CCE to protect sensitive data of applications.

Using KMS to Encrypt Secrets

Dedicated Distributed Storage Service (DSS)

EVS enables you to encrypt data on created disks as required. Keys used by encrypted EVS disks are provided by KMS of DEW, secure and convenient. Therefore, you do not need to establish and maintain the key management infrastructure.

Disk Encryption

Cloud Container Instance (CCI)

CCI allows you to mount EVS disks to a container and use KMS to encrypt EVS disks.

EVS Volumes

SoftWare Repository for Container (SWR)

SWR Enterprise Edition uses keys created in Data Encryption Workshop (DEW) to sign images, ensuring image consistency during distribution and deployment and preventing man-in-the-middle (MITM) attacks and unauthorized image updates and running.

Image Signature

TaurusDB

Transparent Data Encryption (TDE) performs real-time I/O encryption and decryption on data files. Data is encrypted before being written to disks and is decrypted when being read from disks to memory. This effectively protects the security of databases and data files.

Enabling TDE for a DB Instance

Cloud Operations Center (COC)

COC uses KMS to encrypt your host accounts for better security. Before using KMS, create a key first.

Key Management

GaussDB(DWS)

In GaussDB(DWS), you can enable database encryption for a cluster to protect static data. After you enable encryption, data of the cluster and its snapshots is encrypted.

Creating a GaussDB(DWS) Storage-Compute Coupled Cluster

Cloud Data Migration (CDM)

When migrating files to a file system, CDM can encrypt and decrypt the files using the keys provided by KMS.

Encryption and Decryption During File Migration

Data Security Center (DSC)

You can use the encryption algorithms and encryption master keys to generate an encryption configuration for data masking.

Configuring and Viewing Masking Rules

Workspace

You can use the key provided by KMS to encrypt disks when purchasing a workspace.

Purchasing Yearly/Monthly-billed Desktops

GeminiDB

You can use the key provided by KMS to encrypt static data in the database when purchasing a GeminiDB instance.
