# Oracle Database TDE (12c)

> Configuration guide for integrating Futurex PKCS#11 libraries with Oracle Database 12c TDE.

This document provides information about using Futurex PKCS #11 libraries to configure our HSMs with Oracle Database 12c Transparent Data Encryption (TDE). For additional questions related to your HSM, see the Excrypt HSM Administrator guide for you version.

## About Oracle TDE

From the Oracle documentation website: Transparent data encryption (TDE) enables you to encrypt sensitive data, such as credit card numbers, stored in table columns. Encrypted data is transparently decrypted for a database user who has access to the data. TDE helps protect data stored on media if the storage media or data file gets stolen.

## Guardian integration

The Guardian Series 3 introduces mission-critical viability to core cryptographic infrastructure, including:

* Centralization of device management
* Elimination of points of failure
* Distribution of transaction loads
* Group-specific function blocking
* User-defined grouping systems

See the applicable guide in the Futurex Portal for configuring HSMs with the Guardian Series 3, including PKCS #11 and CNG configuration.
