Imagine for a moment that you live in a country where nobody is sure how most of the votes are counted, and there's no reliable record for performing a recount. Imagine that machines count the votes, but nobody knows how they work. Now imagine if somebody found out that the machines were vulnerable to attack, but the agencies that operate them won't take the steps to make them safe. If you live in America, you don't need to imagine anything. This is the reality of electronic voting in the country. Avi Rubin is a computer scientist at Johns Hopkins University and a specialist in systems security. He and a team of researchers studied the code that operates the machines now used in 37 states and discovered terrifying facts, presented in this book.
