I have difficulty understanding why or how it would be so difficult to assure accuracy in vote casting and counting, when it is pretty efficient to trade, swap, buy, sell and probably extort billions of dollars every hour, utilizing the same basic electronics...can someone explain?
==================================================
Efficient? Maybe yes. Sufficiently secure for voting? Definitely no.
The problem can be divided into two main categories of potential attack:
1.) Interception of data streams, transmitted via the public Internet, which could be decrypted and modified.
2.) Intrusion into Internet linked servers storing voting data.
Many Internet voting systems vendors rely upon Microsoft software for hosting and processing data. Such systems have been proven to be spectacularly hackable (think now, of the recent "Blaster" worm, which exploited a design element of Windows networking and propagated robustly across the world).
