Watch an episode of NCIS or CSI and you might get the impression that hacking electronic devices is a simple way to learn all you need to about a person. While these shows tend to gloss over the science of the forensic work, the truth is, most electronic devices only rely on obscurity to keep data safe. Here is an article from Cambridge researchers discussing how to read contents using lasers (but not feverish typing…
Random numbers are a relative concept. In general, random numbers used in digital electronics are called Psuedo-Random sequences. There is a defined algorithm that is used to generate the sequence and does not actually occur in nature. In applications like Flashing a LED, this method is fine. However, for any level of encryption this is unacceptable. Steve Buch at Electronics Weekly writes about how researchers Dr. Marie O’Neill and Dr. Jiang Wu at the University’s…
