参考:http://docs.oracle.com/cd/E11882_01/server.112/e25494/tspaces.htm#ADMIN12327
To maximize security, data from an encrypted tablespace is automatically encrypted when written to the undo tablespace, to the redo logs, and to any temporary tablespace. There is no need to explicitly create encrypted undo or temporary tablespaces, and in fact, you cannot specify encryption for those tablespace types.
