2019年3月23日 · Generating a new Database encryption Key is referred as DEK rotation, look at Alter DEK DDL for the syntax and details. Regenerating a DEK triggers an encryption scan which re-encrypts the entire database with the new DEK.

2016年3月2日 · 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.

TDE does real-time I/O encryption and decryption of data and log files. The encryption uses a database encryption key (DEK). The database boot record stores the key for availability during recovery. The DEK is a symmetric key, and is secured by a certificate that the server's master database stores or by an asymmetric key that an EKM module ...

2024年12月22日 · What Are DEK and KEK? Data Encryption Key (DEK): A DEK is the key used directly to encrypt and decrypt your data (e.g., files, database entries, or messages). Symmetric encryption algorithms such as AES (Advanced Encryption Standard) are typically used here because they’re efficient and optimized for handling large amounts of data.

2025年2月20日 · 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. The protection of the root encryption key changes, but the data in your Azure Storage account remains encrypted always.

2005年7月20日 · The HED is the headline, heading (the title!), and the DEK (deck) is a blurb, or sentence or two that reveals what the article is about. So in the fiber article, YOU’RE FIBER-ED! is the hed, and “Ten Reasons To Get All Fibered Up!” is the dek.

2024年4月3日 · Cryptographic techniques such as Data Encryption Keys (DEK) and Key Encryption Keys (KEK) play a pivotal role in ensuring the confidentiality, integrity, and availability of data. Let's delve deeper into how DEK and KEK cryptography work together to fortify data security, using a practical example to illustrate their effectiveness.

2025年2月10日 · Transparent data encryption (TDE) in Azure SQL with customer-managed key (CMK) enables Bring Your Own Key (BYOK) scenario for data protection at rest, and allows organizations to implement separation of duties in the management of keys and data.

2024年11月9日 · You have a thing called “Database Encryption Key” (DEK) which encrypts your data in MDF and LDF files. So, right before your data is written to disk, Database Encryptio Key (DEK) encrypts it, and right before it’s pulled into your working memory, it’s decrypted.

Data is encrypted using the DEK by the client. The DEK is encrypted by a Key Encryption Key (KEK) that is stored in a cloud KMS. By using a cloud KMS, your KEK resides safely in the cloud, where you can rotate, deactivate, or destroy it, depending on your needs.
