Starting with Oracle Database 11g Release 2 Patchset 1 (11.2.0.2), the hardware crypto acceleration based on AES-NI available in recent Intel processors is automatically leveraged by TDE tablespace encryption, making TDE tablespace encryption a 'near-zero impact' encryption solution. Keep in mind that the table column encryption has a default encryption of AES192. 10 rows created. For comparing normal data and encrypted data, we prepare a control test. (5) We can check the information about the Keystore in V$ENCRYPTION_WALLET view. The environment is single instance database. Version 19.11.0.0.0. Before we can set the TDE master key in the keystore, we should open it. AutoUpgrade with Transparent Data Encryption (TDE) The performance overhead of using AES256 is roughly considered 40% slower than AES128, therefore, I would recommend AES128 which is a balanced solution.
