Hello Folks,
I read a paper on a crypto site some years ago which described the perfect
electronic transaction device. This device had a keyboard, display,
embedded crypto processor, and possibly even a biometric scanner and RF
link. The paper did a good job explaining why each of these features were
necessary for total security and privacy. It might have been on Chaum's
site (digicash.com). Does anyone know what I am talking about and where I
might find this or a similar paper?
Thanks,
David Brunell
