The Key Vanishes: Scientist Outlines Unbreakable Code

Could the randomization inserted into the GPS system be used for a global
random number server? I think it was in the form of time jitter, so you
would have to use the difference between successive readings.

if this is true ($100K to launch) I'd help defray some of this cost just as
a mechanism to distribute/manage my own keys. but i suspect the satellite
itself is pretty expensive. when I looked into this a few years back the
annual management of a satellite was about $250K. I assume it's less
expensive now? also key management can be handled from the ground pretty
well. i wouldn't use the satellite as the source of the key, i'd use it as
a kind of reflector instead.
instead of launching a dedicated satellite why not rent time on several
existing satellites and use them as reflectors? it's a lot less expensive
and key management can be handled from the ground.

Look into experimental rocketry and 'can satellites' (there's a link on /.
about the later). The cost to put a bird in space is probably around
$100k right now.
