EPTP.S. I was thinking of doing the Enigma, but there are already two groups in my class of 12 people doing it, and that wouldn't work.

The end of the semester for school is near, and for my Cryptography class we have to do a project on something Cryptography related. D: | ||

The idea of a magic square is pretty neat in itself: http://en.wikipedia.org/wiki/Magic_square Edit: Or you could just go through a Crypto-Gram Newsletter archive and find something there. I've subscribed to it ages ago as it has some really cool articles about online security and stuff like that. http://www.schneier.com/crypto-gram.html | ||

RSA is a very elegant mechanism and interesting to explain and understand. Also explain the advantages and applications of public key cryptosystems while you're at it. Or demonstrate a transposition cypher, that should work well on the blackboard. | ||

That's what I did for my Information Age class.. it's actually pretty fun and the math behind is quite elegant ;-) That's possible, as we've been going over RSA the past couple weeks. Today in class actually the teacher was writing code that does exactly that with Maple on the projecter. | ||

If somebody else is already doing RSA, you could demonstrate one of the weaknesses of RSA, i.e. that if you have knowledge of the public key and keep encrypting the message with it, you will eventually get back to clear-text, and a lot faster than trying to factorize to get the private key. So if something was encrypted that can easily be verified whether you have arrived at cleartext (a text message in a known language for example), things become interesting ... Or on a related topic you could demonstrate how to play rock-paper-scissors (or poker, same idea, just more complicated) over the phone. Two more ideas: compression algorithms, e.g. ZIP or GIF. Or checksums, which are pretty useful for just about anything, from an ISBN to pharmaceuticals, to network packages, credit cards etc. Discuss not only how and why they work, but also how you can use the checksum to reconstruct the original if something went wrong e.g. through an omission or a transposition. | ||

Once you have also explained the public/private key concept, it's also easy to link with useful applications beyond "encryption", such as digital signatures, authentication (e.g. the GSM network uses something similar when you switch on your mobile to make sure you're not impersonating) etc. If somebody else is already doing RSA, you could demonstrate one of the weaknesses of RSA, i.e. that if you have knowledge of the public key and keep encrypting the message with it, you will eventually get back to clear-text, and a lot faster than trying to factorize to get the private key.
