Code Breakers
One for the scrap book
This Easter holidays 'er indoors and I went to Bletchley Park, home of the cipher and code breakers of WWII.
Fascinating place with a lot of stories to tell. The place reeked of history populated by eccentric British "Boffins". Some of the guys working there as curators now actually worked there in the '50's and '60s when the place was still a central military establishment.
Have to say, the reverse logic, techniques involved plus some of the maths employed went right over my head.
Loads more to see than depicted on these photos, but for those that are interested.....
lots of enigmas (and variations to excuse the pun)
early luftwaffe
a four wheel army variant. This is the one that got stolen a few years back and was held to ransom
wiring the cog to the thingy.. this is where it started to get complicated
a set of encoding wheels
read the insert (a lot of the rotors thingies are actually the same as found in old fashioned telephone exchanges)
Colossus - rebuilding a replica of the original.
Ther are no full plans of the machine, Apparently the replica is based on 4 photograpghs of the original and 2 pages of engineering notes that should have been destroyed
The message to be decrypted is first loaded onto a paper tape (each row of punch holes corresponds to a single letter
and the tape stream is fed as an endless loop into colossus. The machine has no memory, so the data is continuouslly reloaded... this is 1943/44 remember
the paper strip runs at approx 30 mph
but he still has a lap top to check e-mail
This is a bombe, not a computer, but a mechanical machine that was used to help deduce the initial sequencing code that was used to encode enigma ciphers. The code was changed daily from one of several thousand million possible combinations. This machine did not crack it, but produceded possible combinations that it could be
the wiring at the back....
Will have to go back again to just start to understand how it works.
It really does boggle the mind to understand how they reverse engineered it.

Re: Code Breakers
Nice piccies, G! And I´m sure that those guys are still able to tell some real interesting stories about crypting, decrypting, bloolean and logical expressions, on and off, wainscotting and even more than that ...
Anyway, thank you, G!

Re: Code Breakers
Yep I had that too stu but a quick trip to the doc's sorted it. That and some big blue fuzzy pills
Great pics and some nice background to them Gurbs. I might just have to pop down there sometime and have a look see.

Use the keyboard configuration ...
'a' is 'Q', 'b' is 'w', 'c' is 'E', etc.
group in sets of five,
'0's' are null.

I don't see why codes are necessary. Trying to understand the Sunday 'Political' section of the paper is hard enough. With 'spins' and half truths and exact definitions and outright lies, the truth is pretty well safe from being discovered.

Gurb,
Interesting posting. I'll show it to my son, he was cyrpto maintenance in the USMC and now does almost the same thing in the Air Guard.

The lesser half speaks in code all the time, try cracking the womens secret language heh
"Take garbage out?"
"I see the dishes aren't done after I cooked the sunday roast!"
"Can you change the baby?"
(I think that means swap it for one that doesn't leak!)
"When are you going to...?"
"Isn't it about time you...?"
"Those shelves arn't straight!"
"Could you pick my mother up after work?"
I just don't get any of it, why can't she tell me in simple English!
