In fact, it's very useful -- what do you think the initial diffie-hellman
exchanges are doing with pfs? Encryption without (strong) authentication
is still useful for dealing with passive listening. It's a shame, for example,
that wifi security doesn't encrypt everything on an open AP to require
attacks be active rather than passive. It's really easy to just scan the
airwaves, but I probably don't need to remind you of that.
