Codes and Cryptography


A general history, emphasizing the mathematics and techniques, being comprehensive in showing all ways to encode; and letting readers apply the codes. For example, a web page with a working enigma machine. Be sure to include the “the machines of cryptography.” Go into detail on public key encryption.

A very interesting book on the history and mathematics related to codes is "The Code Book: The Secret History of Codes and Code-breaking"


This would prove another useful training aid for my technology classes as we explore the history behind the encryption systems that many online institutions (ie banks) now use.
I have a particular interest in enigma, typex and sigma encoding machines and how well they stack up against today's high bit encryption systems. (They don't).

On a related note, a brief overview of information theory (Shannon etc) would be helpful for this topic.

Crypto-currency (ie Bitcoin) could work well here, particularly for showing the public/private key relationship.
