Activities for Discovering Cryptology
These are links to interactive demos and/or activities for use in a Mathematical
Cryptology class. Most of the demos use SAGE software embedded on a website.
(No access to or knowledge of SAGE is required.)
- Activity: Make a Paper
Enigma (external link to Mike Koss' website) Both the pdf handout and
the online simulators are really nice.
- Activity: Examine permutations and cycles
related to Polish Mathematicians work on breaking Enigma.
- Enigma-like cipher challenges
and information on world war II crypto (external link to Nova's Decoding Nazi
- Activity: Make a Cipher
Disk (external link to Kids Make Stuff Website) This is the same as the
cipher disk used by Confederate troops with the Vigenere cipher, but can also
be used for the simpler shift cipher.
- Information on American
Civil War Cipher Disks (external link to Civil War Signals Website)
- Activity: Make a Union
Cipher Disk (external link to Civil War Signals Website). This is essentially
a monoalphabetic code with a few additional symbols for common words or word
ending. Its symbols are suitable for communicating via flags.
