No more National Science research grants, etc.

Roger,
What you say is almost obvious in the context of today's technology.
OTOH, if Shor's algorithm eventually trashes RSA encryption, there
will likely be an immediate search for one way PK systems with
trapdoors that run in qubit time and that are nearly impossible to
reverse, even using a quantum computer. Such a sweep for candidates
must clearly include chaotic systems and synchronizing neural nets.
Want to bet there is not a better solution in the quantum computing
technology space?

This is not exactly on topic but if you are looking for a subject
which might be suitable for some serious study, it is possible that
http://xyz.lanl.gov/abs/physics/0508135 Stealth Communication:
Zero-Power Classical Communication,
Zero-Quantum Quantum Communication and Environmental-Noise
Communication has some underlying value.

No chaotic system seem to be as random as what they use routinely in
crytology.

Also, note that the first paper referenced in my post does not depend
on algorithmic noise--that is the least of its problems.

Finally--Claude Shannon, the inventor of Information Theory, wrote a
paper on [absolutely] Secure Communication with analog signals. I have
never found it and continue to wonder what Shannon thought the
equivalent of a one-time pad for analog communications was.

Any idea what Shannon was thinking. Just the gist of his concept
would be appreciated.
