sqlldr on unix - any idea how to implement security?

We are using Oracle 8.0.4 on unix system and loading data into tables using SQL*Loader.
The loading process should be run by cron [no way to enter passwd manually] For security purpose :
we do not want anybody get user password doing a ps when sqlldr is running [no "sqlldr user/pwd file=.."].
we do not want user password clearly written in files.

Any ideas how to use sqlldr with those constrains?

Thank you.
