I'm sure you'll like Rabbit. You might agree with the approval
accorded the Greatest Lesser Scouchamouch, too. There are a few
head--shake moments in and around the library, but if you wanted it
all to make _sense_ you wouldn't be reading these guys.

It's all right. Quantum computing offers very large polynomial time
reductions, but there are algorithms that require exponential (2^N)
time on conventional computers, and if that isn't sufficient, we can
go for 2^2^N or better. I'm sure we'll find a suitable quantum
trapdoor problem to base a new public key infrastructure on, once it
occurs to the right person that we need to look for such a thing.
There are algebraic structures that are much harder to factor than
mere integers, and other spaces that one might investigate.
