David,
this sounds very interesting, but please clarify... what is
the advantage of such a system over a simple approach like this:
"I hand you a RSA public key, and next time I come around, you
send me a random message encrypted with this public key. I'll
prove that it's me by decrypting the message."
?
Greetings, Norbert

i could hand you an applet, and say "use this applet
to verify who i am next time i come around"
I'm working on such an authentication scheme. It turns out that this is
not a trivial problem to solve. It's been solved mathematically, but
there aren't too many real-world applications. I'm working on implementing
this in a way that would prevent someone else from forging your "applet".
Mail me directly if you would like to talk about this further so that we
don't clog the main list.
David
