Re: code validation?

Hello Paul:

Try looking under the word, "hash." A hash is sort of
a glorified check sum system that is ran on the
original software. When the hash of the CD disk
running the software is ran at startup on the voting
equipment, the number generated has to be the same as
the publically published originally generated hash.
Additionally there would be various legal and
adminstrative techniques involving multiple, intersted
witnesses in the CD duplication process. Foolproof?
No, but still very tamper resistant and compliant with
a good risk management approach to security IMHO.

HTH, Ed Kennedy
