This is quite a difficult one, and as usual in the field of security depends on how
the data is and how difficult you want it to be for an attacker to obtain it.
If you let us know what type of data this is and how well it has to be protected, maybe we
can help more. "security reasons" is a bit vague, but I can understand that you don't want
to give too much away.
I can say one thing though, in order for the data to be indexed by MySQL , it has to be in
an unencrypted form somewhere in the database. There is no way I know to get around
this, but I hope someone can correct me :)
