Nov 27, 2024 · For a given server, a CMK, called the key encryption key (KEK), is used to encrypt the service's data encryption key (DEK). The KEK is an asymmetric key stored in a customer-owned and customer-managed Azure Key Vault instance.

The wrapping key is generi-cally called a key encryption key or KEK. In CMK, the MK needed to decrypt the EDEK is held by the customer’s Key Management System (KMS). You ask the KMS to decrypt the EDEK. If the KMS grants access, it will unwrap and return a DEK which you in turn use to decrypt data. You then wipe the DEK from memory.

Apr 16, 2025 · A specific type of customer-managed key is the "key encryption key" (KEK). A KEK is a primary key that controls access to one or more encryption keys that are themselves encrypted. Customer-managed keys can be stored on-premises or, more commonly, in a cloud key management service.

Feb 20, 2025 · When you configure customer-managed keys for a storage account, Azure Storage wraps the root data encryption key (DEK) for the account with the customer-managed key in the associated key vault or managed HSM.

Mar 2, 2016 · The FDE software will randomly generate a DEK, then use the user's password/keyfile/smart card to create a KEK in order to encrypt the DEK. This mechanism allows the user to change their password without having to decrypt and re-encrypt the entire volume.

Apr 25, 2023 · Most cloud providers, including Azure, will protect DEK by encrypting with an asymmetric key called Key Encryption Key (KEK). It is kind of a encryption wrapper around DEK, usually called...

Jun 8, 2020 · Key encryption key (KEK): An encryption key used to encrypt the DEKs. A KEK that never leaves Key Vault allows the DEKs themselves to be encrypted and controlled. The entity that has access to the KEK might be different than the entity that requires the DEK.

Apr 17, 2025 · This persistent disk and bucket data is encrypted using a Google-generated data encryption key (DEK) and key encryption key (KEK). The CMEK feature lets you create, use, and revoke the key...

Dec 5, 2022 · Data encryption key (DEK) is designed for use by the Azure Database for MySQL service to encrypt/decrypt data. The CMK, also known as the Key Encryption Key (KEK), is used to encrypt and decrypt the Data Encryption Key.

Apr 11, 2023 · For a given cluster, a customer-managed key, called the Key Encryption Key (KEK), is used to encrypt the service’s DEK. The KEK is an asymmetric key stored in a customer-owned and customer-managed Azure Key Vault instance.
