Hi Gents, can anyone remember an article on the successors to Enigma (with pictures) that was published in a technical magazine in the past few years? I'm looking for a link.

Many thanks, Ed

Not sure what you are referring to Ed but does this help at all

You'll find info on the British, later than enigma, machine under 'typex'.

Thanks for that Gents.

Hi Ed,

There is a lot of interesting information on various types of cryptographic machines here.

Hi Ed,

Here is a couple of links that I found interesting:

It was the Lorenz machine used by the high command as an encrypted teletype known at Bletchley as 'fish' and that was what Collossus was used to decrypt. Enigma was mainly decrypted using the 'bombe' machines developed from pre-war work in Poland.

I worked on BID580, BID660 and BID150. The nearest thing to the Enigma I worked on was the KL7 seen here on Wiki:-
http://en.wikipedia.org/wiki/KL-7

An American machine, the printout was on paper tape that had a peppermint flavoured gum. I was told that chocolate and strawberry flavours were also available but never came across them. The KL7 was OK until a unit was captured in Korea and I guess the Chinese must have stripped it down and analysed how it worked. After that it was seldom used (if ever) as a main cyphering machine but was used for double encryption. For example, a decoded message would be received on the BID580, addressed to the Captain of a vessel but would be total rubbish. The Captain would then put the message through his own private KL7 machine in his cabin, so the message became 'for his eyes' only.

The Lorenz machine is also on Wikipedia. It reminds me that 'fish' was referred to as Tunny(tuna fish)
