The idea to use quantum physics to get rid of the shared randomness is
nice. I'm not sure that the approach outlined by Hal can be made to work.

because the variation of the physical
properties whose measurement these systems rely on is very large. Increasing
the reliability would also increase the false rejection ratio, making the
systems unusable.
There's a paper on this in CARDIS '2000 of last September.

Actually, this sounds more like applying fault tolerance (e.g. byzantine
agreement) techniques to increase security and dependability of your system.
Also related are secret sharing techniques and methods to securely compute a
function on a partially truste

usable and user friendly to me - as far as any secure email product could ever
be completely be user friendly... The user has to do more stuff than usual, and
has to have some understanding of what is going on in order to judge whether
his/her security requirements have been met.
