I was using TDE and tried to select the column after encrypting and closing the wallet. Its shows me an error. Thats good. But my question is; Is there any way to restrict some users and allow other users using the same column?.

If i give the wallet key to those users then i won't have enough security for my data.

My scenario is i have some users whom i should give access to SSN column and certain users to restrict the same. Both of them has the previllage to use the select query. When the restricted users use "select *" query they should not be able to view the ssn column.

Please help i am a newbie in oracle

You miss the purpose of TDE which is NOT controllong access right but prevent from theft.

Use FGAC or DBMS_CRYPTO but not TDE.

Once again FGAC or better and simpler VIEW.
