TDE Tablespace Encryption Certified with EBS 11i

Steven Chan

Oracle Advanced Security is an optional licenced Oracle 11g Database add-on.  Oracle Advanced Security Transparent Data Encryption (TDE) offers two different features:  column encryption and tablespace encryption.  TDE Tablespace Encryption is now certified with Oracle E-Business Suite Release 11i.  

What is Transparent Data Encryption (TDE) ?


Oracle Advanced Security Transparent Data Encryption (TDE) allows you to protect data at rest. TDE helps address privacy and PCI requirements by encrypting personally identifiable information (PII) such as Social Security numbers and credit card numbers.

TDE is completely transparent to existing applications with no triggers, views or other application changes required. Data is transparently encrypted when written to disk and transparently decrypted after an application user has successfully authenticated and passed all authorization checks. Authorization checks include verifying the user has the necessary select and update privileges on the application table and checking Database Vault, Label Security and Virtual Private Database enforcement policies.

Existing database backup routines will continue to work, with the data at rest remaining encrypted in the backup. For encryption of entire database backups, TDE can be used in combination with Oracle RMAN.

New in Oracle Database 11g, the Oracle Advanced Security now includes support for tablespace encryption.

When a tablespace is created through Enterprise Manager or on the command line, an option now exists to specify that the file be encrypted on the file system. When new data is added to the new tablespace using the insert command or datapump, entire tables will be transparently encrypted. When the database reads data blocks from the encrypted tablespace it will transparently decrypt the data blocks.

With this certification, Oracle E-Business Suite Release 11i environments can be migrated to the latest 11gR2 version of encrypted tablespaces. For more information, please refer to:
