Transparent Data Encryption

Oracle Advanced Security with Oracle Database 11g Release 2 provides transparent data encryption to support your compliance efforts. Applications do not have to be modified and existing applications will continue to work seamlessly as before. Data is automatically encrypted when it is written to disk and automatically decrypted when accessed by the application. Key management is built-in, eliminating the complex task of creating, managing and securing encryption keys.

New in Oracle Database 11g Release 2: Unified master encryption key

The master encryption key for TDE tablespace encryption and TDE column encryption are now combined to one unified master encryption key. This allows transparent re-key operations for both TDE tablespace encryption and TDE column encryption, regardless if the master encryption key is stored in the Oracle Wallet, or in one of the certified Hardware Security Modules offered by RSA, SafeNet, Thales (incl. nCipher) and Utimaco.

New in Oracle Database 11g Release 2: Encryption support for Oracle Exadata

Customer no longer have to choose between security and compliance on one side and high performance computing on the other side. With Oracle Database 11g Release 2, the tablespace keys for TDE tablespace encryption, or table keys for TDE column encryption, are available to the intelligent storage cells, where encrypted data is now decrypted before pre-filtering of the result set takes place.

New in Oracle Database 11g Release 2: Automatic Wallet Management across RAC instances

Open or close the Oracle Wallet, or re-key the master encryption key on one RAC instance, and the changes are propageted automatically to all other instances.
