The sky is not falling.
The attack gets the attacker eleven bits - at the cost of being
an extremely narrow attack with few practical uses. So add
another 28 bits.
Moore's law tells us the attacker gains a bit every 18 months -
the attack merely means we have to go for larger widths sixteen
years ahead of schedule.
