Stony Stevenson writes to tell us that in celebration of the opening of the National Museum of Computing, members of the public are being challenged to take on a rebuilt version of Colossus, the world's first programmable digital computer. The Cipher Challenge will take two groups of amateur code breakers and pit them against one of the original Lorenz cipher machine used by the German High Command during World War II. "The encrypted teleprinter message will be transmitted by radio from colleagues in Paderborn, Germany, and intercepted at Bletchley Park by the two code-breaking groups, one using modern PCs and the other using the newly rebuilt Colossus Mark II."

      Colossus documentation and hardware were classified from the moment of their creation and remained so after the War, when Winston Churchill specifically ordered the destruction of most of the Colossus machines into 'pieces no bigger than a man's hand'; Tommy Flowers personally burned blueprints in a furnace at Dollis Hill.

          That would be like developing the atomic bomb, and then promptly destroying every trace of it because it's a dangerous weapon. Countries that develop new dangerous weapons tend to keep them around (and use them) to keep the advantage they got from having it.

        The main reason for the destruction was that we no longer needed the same number of machines. We did keep two though I believe which were moved to GCHQ (General Communications Head Quarters - Our eavesdropping department). We certainly did not destroy them all but much of what they did after the war will still be classified.

    The article doesn't explain how 1940s hardware competing with modern hardware is a remotely interesting contest. The reason is that the Collosus machines (Collosi?) were both highly specialised for the task, in that they could not do anything but simulate a Lorentz machine very fast, and of course massively parallel. In particular, Collosus was not Turing-complete, so it could not execute arbitrary programs (in the modern sense) - the honour of first Turing-complete machine usually goes to the ENIAC, although this is hotly disputed. So, this might be an interesting contest, although I would still expect a good modern implementation to win. More information, as always, at Wikipedia [wikipedia.org].

      "The article doesn't explain how 1940s hardware competing with modern hardware is a remotely interesting contest."

      Without it being spelled out to me, I am thoroughly taken with this idea. (only true computer geeks need apply, basically)

      I think it would be cool to participate in this, but I would especially like to be on the Collosus team just to get to play with this icon of computer geekdom. I suspect that the modern pc's could smoke Collosus (with the right setup), but this gives a chance to gauge our progress, compare apples and oranges like only a comp. geek can, and otherwise rejoice in our geekiness.

      So admittedly, this isn't interesting for just anyone-even here on /. , but to some of us, this is just too much fun/interest to pass up.

      We see quite a few stories about comparisons between PS3 'super computers' pitted against older supercomputers, we see ad hoc distributed systems compared to older super computers, so why not modern PC's compared to The Super Computer that started it all. (okay, that last bit may have been over the top, and not real accurate...but come on man!)

      On the Spock Scale, I rate this one as:

      I had the luck to visit the Bletchley Park facility earlier this year. (Are you a True Geek? Do the same. They need the money and I mean that.)

      That piece of '40s hardware might look like a crossbreed of a Wells time machine and a phone exchange, but it was (the replica is) incredibly fast. At one very specific task only, solving one of a class of problems. Do not overestimate the speed of a modern PC - it is kept back by years and years of inefficient programming. The people working on Colossus were Real Programmers of the first order (no quiche!). I'd expect the race to be pretty close.

  • A working replica of the code-breaking device will return to active service as part of the Cipher Challenge on 15 November to mark the launch of the National Museum of Computing.


    So it looks like they are using the original wheel combinations, which are widely known. This means I could probably emulate Colossus on my calculator and still solve it faster.

      • Pitty they could not get the original girls back. When the machines were rebuilt, they came to B.P. and went back into their old routine. During the war after a while they would "guess" possible start position combinations. No time for that, shame. I was deeply impressed with their retained "bone knowledge" at the time. Also a shame not replicating "Y" stations, and sending the intercepts by motorbike.

        Alas, while my Grandfather fought in the Pacific and I have read a bit on the Enigma, I'm not sure what some of these are. What are "Y" stations, "bone knowledge" and by "guess" do you mean making a prediction and coming out very close to the actual starting combination?

    WWII might have been a great deal more expensive in terms of humans lives, duration, and overall destruction is it wasn't for the people at Bletchley park and their counterparts in the US Army Signals Intelligence Service. It's unfortunate that their contribution remained a secret for so long. Imagine how much damage Yamamoto could have done if his strategies and feints weren't all known to the Americans or if all the German troop movements weren't deduced from their communications.

        He is truly the father of modern computing and he achieved a lot in his short life. He was monumental to the Allied war effort and a once in a generation math genius. It's really too bad the people of his time couldn't look past his sexuality.

    Bletchley Park also used poems [wikipedia.org] as cypher keys. This [wikipedia.org] is probably the best as literature, but looks a bit repetitive to be secure.

    • That (famous) poem was written by Leo Marks who was the codemaster for the British Special Operations Executive. He spent most of the war wishing he was working at Bletchley Park but didn't (although they knew about his coding schemes). His autobiography "Between Silk and Cyanide" is a humorous and very moving account of his time during the war and some of the agents he met who lost their lives. That poem was written for his girlfriend who was killed in an aircraft crash - later he passed it on to Violette

    • Reading that German text, the Bletchley Park people wanted guarantees that the Germany would not declare the Lorenz SZ42 to be 'spoils of war' ('war loot' does not have the same ring about it) and just keep it. Presumably that is the reason the Allies have them and the Germans do not in the first place.

      The German Ministry of Defence (DoD over there) and the office of the Bundeskanzlerin were also involved in the assurances that the SZ42 would not be kept.
