Last updated on FEBRUARY 28, 2019

Applies to:

Advanced Networking Option - Version 11.1.0.6 to 11.2.0.4 [Release 11.1 to 11.2]
Information in this document applies to any platform.

Purpose

In 10gR2 version, Transparent Data Encryption was first introduced at the table column level.

The 11g version introduces an enhancement to the 10gR2 TDE :  Transparent Data Encryption is now available at Tablespace level. You can encrypt any permanent tablespace to protect sensitive data except SYSTEM, SYSAUX, UNDO.

This means that creating a segment in an encrypted tablespace encrypts all data of the segments stored in the tablespace: all segment types are supported for encryption, including tables, clusters, indexes, LOBs, table and index partitions, and so on.

Tablespace encryption is completely transparent to applications, so no application modification is necessary.

Scope

This bulletin explains this new feature for all DBAs and developers requesting greater user usability of encryption. This document assumes familiarity with 10gR2 TDE as discussed in <note 317311.1> .

Please also check the Transparent Data Encryption Frequently Asked Questions for more information about tablespace level Encryption such as working with an HSM device etc.
