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 on a keyboard for software that is clearly graphical in nature.). That sound crazy right? Don’t forgot Princeton has guidelines on security based on the fact you can freeze RAM to extend its retention.

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 Institute of Electronics and Communications Information Technology (ECIT) has developed methods to generate true random bits digitally.
