The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography by Simon Singh

5.0

Intriguing and yet accessible, even to a mind not schooled in mathematics and physics. A balance between science and the personalities involved in cryptography, and Mr. Singh does a great job of constructing helpful analogies to assist the novice in figuring out how the various elements of this science work.
