Even if the FCC agrees to allow the use of encryption and digital
signatures for secure logins, isn't it possible for an intruder
to wait until you'd completed your secure login and then overpower
your signal with a stronger or closer transmitter?  It would seem
that every transaction, not just the initial login, would require
some protection.
