I could be wrong.

I belive the 'auth' for broadcast is private key auth; it would require that
key number N have the same value in the ntp.keys file on your server and on
your clients.

Without auth, BadGuy can send time to your clients and you risk having the
client machines believe the BadGuy.

This might be discussed at http://ntp.isc.org/Support/ .
