Each TDE table key is individually encrypted with the TDE master encryption key. When a table contains encrypted columns, TDE uses a single TDE table key regardless of the number of encrypted columns.

Security is enhanced because the keystore password can be unknown to the database administrator, requiring the security administrator to provide the password. Using an external security module separates ordinary program functions from encryption operations, making it possible to assign separate, distinct duties to database administrators and security administrators. Storing the TDE master encryption key in this way prevents its unauthorized use.

For this external security module, Oracle Database uses an Oracle software keystore (wallet, in previous releases) or hardware security module (HSM) keystore. The user or application does not need to manage TDE master encryption keys.įigure 2-1 TDE Column Encryption Overviewĭescription of "Figure 2-1 TDE Column Encryption Overview"Īs shown in Figure 2-1, the TDE master encryption key is stored in an external security module that is outside of the database and accessible only to a user who was granted the appropriate privileges. Oracle Database automates TDE master encryption key and keystore management operations. The database manages the data encryption and decryption. You do not need to modify your applications to handle the encrypted data. (See Oracle Database Administrator’s Guide for more information about online table redefinition.)

You can encrypt data with zero downtime on production systems by using online table redefinition or you can encrypt it offline during maintenance periods. Database users and applications do not need to be aware that the data they are accessing is stored in encrypted form. An application that processes sensitive data can use TDE to provide strong data encryption with little or no change to the application.ĭata is transparently decrypted for database users and applications that access this data. Data from tables is transparently decrypted for the database user and application. You do not need to create auxiliary tables, triggers, or views to decrypt data for the authorized user or application. Using TDE helps you address security-related regulatory compliance issues. Transparent Data Encryption (TDE) ensures that sensitive data is encrypted, meets compliance, and provides functionality that streamlines encryption operations.Īs a security administrator, you can be sure that sensitive data is encrypted and therefore safe in the event that the storage media or data file is stolen. See Oracle Key Vault Administrator's Guide for more information. For example, you can upload a software keystore to Oracle Key Vault and then make the contents of this keystore available to other TDE-enabled databases. This enables you to centrally manage TDE keystores (called TDE wallets in Oracle Key Vault) in your enterprise. You can configure Oracle Key Vault as part of the TDE implementation. To prevent unauthorized decryption, TDE stores the encryption keys in a security module external to the database, called a keystore. TDE encrypts sensitive data stored in data files. To protect these data files, Oracle Database provides Transparent Data Encryption (TDE). Oracle Database uses authentication, authorization, and auditing mechanisms to secure data in the database, but not in the operating system data files where data is stored. TDE helps protect data stored on media (also called data at rest) in the event that the storage media or data file is stolen. Transparent Data Encryption (TDE) enables you to encrypt sensitive data that you store in tables and tablespaces.Īfter the data is encrypted, this data is transparently decrypted for authorized users or applications when they access this data.
