How to bind user to category list on home page

there are good plugins out there which hide page listings and pages for defined users; so that page list and page itself only appears when specific user is logged in.

There are also plugins to restrict categories to defined users.

However, I cannot find any plugins to allow a specific category in list to be hidden when the specific user is not logged in.

Can anyone help point me in the right direction or provide the necessary code?

thanks very much
