Hi,

I am doing a research paper in history talking about how Cryptographic Machines influenced world war II.
Do you guys know about those machines , and what where their algorithms ?

Where there other machines than "Enigma" and "Sturgeon" ??

Thanks a lot for your info.

What kind of information are you looking for? I doubt you'd be able to find an Enigma "users manual" on the web, but there should be plenty of good background on the contribution that cracking Enigma had on Allied operations. The book "ULTRA Goes To War" by Ronald Lewin covers this history and some of the cryptographic theory behind Enigma. It's out of print, but you can order it here:

http://www.amazon.com/exec/obidos/tg/detail/-/0070374538/qid=1095364376/sr=1-1/ref=sr_1_1/102-9604465-6880154?v=glance&s=books

By the way, the Danish Resistance Museum in Copenhagen has an original Enigma on display. It's a fascinating museum, and well worth a visit.

Remember there was lots of versions of the Enigma so that might be interesting to discuss in your paper.

Others to my knowledge (it would be good to double check them):
-The ECM Mark II, also known as SIGABA, M-134-C, and CSP-889 (American)
-PURPLE (Japanese)
-Lorenz SZ40/42 (German)
-M-94 (American)
-Strip Cipher M-138-T4 (American)- Not a machine but stilled used in WW2
-TYPEX (British)

Thats all I can think of although I gurantee there are lots more obscure ones e.g. those used by countries not listed here.

Also the Navajo code talkers might be an interesting subject to explore -
http://www.lapahie.com/NavajoCodeTalker.cfm although they aren't machines so I don't know how useful this would be to you.

A list of some other machines are here: http://www.eclipse.net/~dhamer/cipher_machines.htm

Hope that helps.
