Assuming you're using ssh, your best bet is to take advantage of the facilities it already has for doing this, such as setting up public key authentication.

Update: To clarify, ssh's authentication facilities will help run the remote script as the right user to begin with, replacing sudo; they won't help you simulate keyboard input to another script. For that, use ssh -t and Expect.
