Last month I attended Cryptoday 2009 – a workshop on cryptography and security hosted by the Computer Science department of the Technion. Amongst the lectures there was one by Prof. Moni Naor of the Weizmann Institute that focused on the feasibility of, and defense from, certain kinds of attacks on security that circumnavigate traditional encryption by attempting to read information directly from the physical medium. Attacks which are known as “side-channel attacks”.
I’m mentioning this because the June issue of Scientific American Magazine published a really interesting article on the topic titled “How Hackers Can Steal Secrets from Reflections” which explains this kind of attack in a simple and interesting language. It’s a little far fetched, but well worth reading.
