TDE的原理就是 master key 来加密 AX5cR+8gOE8YvwjehRgtkkkAAAAAAAAAAAAAAAAAAAAAAAAAAAAA  , AX5cR+8gOE8YvwjehRgtkkkAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 再来加密tnew08_a。

RMAN TDE就是:
  1. [oracle@station36 wallet]$ rman target /

  4. connected to target database: ORCL (DBID=1507385682)

  5. RMAN> show all;

  6. using target database control file instead of recovery catalog
  7. RMAN configuration parameters for database with db_unique_name ORCL are:

  23. new RMAN configuration parameters:
  24. CONFIGURE ENCRYPTION FOR DATABASE ON;
  25. new RMAN configuration parameters are successfully stored

主密钥 来 加密备份集头部里的密钥 , 备份集头部里的密钥再来加密备份集。
