Tackling Enigma (Turing's Enigma Problem Part 2) - Computerphile

Poland was invaded by Germany and Soviet Union. a half truth is a lie.

So what did the British use for encryption?

How Cloud Computing Helped to Win WWII

Now there's a clickbait title!!

Amazing

The last few minutes describe what's basically distributed computing, decades before arpanet was in anyone's dreams

This yank thanks you. I now know what I can tell my dad about my great, great grandfather. He never understood why he was told that gg grandad said he helped build bombs and to tell no one. Thank you for deciphering this.

America: cloud irl

At the first minutes, I thought that he ridiculed Enigma, but a few minutes later I acknowledged that „military enigma“, esp. Navy enigma, was a tough target to break. Only by gathering code books from weather ships etc. it could be solved sometimes, while many messages remained encrpyted. I like that he gives credit to the Poles and Paul Alexander, who really deserve it for embracing on this quest.

I always thought The Bombe was named that way for the same reason the first tank was named to sound like a water tank, so that if any eavesdroppers or spies overheard that there was work being done on a new "Bomb", they wouldn't think much of it. Its nonetheless interesting that it was actually named as a nod to the polish Bomba which itself has a lot of speculation about its name's origin.

Never really understood why machine did not change an A into an A

actually: "Erloschen ist Leuchttonne" with double t, because you put the term "Leucht" in front of the word "Tonne".

Beautifully presented, and reasonably intelligible to non mathematicians like me...thankyou!

If this seems like complicated work, imagine doing it in a world where you had to build the worlds first computer. You are trying to solve a problem that requires an answer that human beings have never had in our spices history before. It was literally an impossible problem in the world that existed before you changed the world to solve it.

Manually going after the Enigma -- Ha! you had better chances of shining a laser into the night's sky, hitting an alien and expecting him to shine one back at you.

It’s amazing that some of this information was still declassified until 2010!

Polscy matematycy i kryptolodzy: Marian Rejewski, Jerzy Różycki i Henryk Zygalski, którzy dokonali przełomowych odkryć dotyczących niemieckiej maszyny szyfrującej Enigma i złamali jej kod
1936-1939. Po przegranej kampanii wrześniowej dokumentacja wraz z urządzeniami została przekazana Brytyjczykom.

"The Secret in Building 26" is a great book on NCR's Bombe program!

never heard of the bomba, just the other machine

Felt like listening to your old granpa talking about "My time". Very interesting series!

If the germans had of used simple 'one time pads' (like the USSR) instead of some machine contraption, Bletchely Park would have been a dismal failure.

Listening to this man speak is a delight

the approach from the staff of bletchley park, regarding the cracking of the enigma, was brilliant indeed . which were the cryptographic methods that the allies were using to transfer their messages ???? were the germans trying to break them ???

hmm

Imagine solving this without a computer. What a pain-in-the-ass

I love the Raspberry Pi bear in the both Computerphile Enigma videos!

What's with all the sudden zooming in and out? Trendy, i suppose, but gets tedious.

UNS UNS BABY

That clumsiness, combined with the fact that he was experimenting with gold-plating spoons (a process which requires potassium cyanide) when he died, means that many people now believe Turing’s death was an accident rather than suicide. The apple that he supposedly laced with cyanide was never actually tested, and his symptoms were apparently more consistent with cyanide inhalation rather than ingestion.

If the germans send in the beginning and the end of the message a random number larger than 24 of random characters wouldn't that made it almost impossible to crack?

RESPECT to Simon Singh who told me about these things years ago also. Love the book.

"so we would send the menu to the Americans and they would load menu on their bombe and give us the result.

I guess you would call them programs now."

Computers running programs before we had words for them.

Errr.... Imissed Part One of this BUT wasn't this just a permutation of The Lorenz Cypher?

To find a man that can explain this in such detail and order .... This guy is a genius and such a great guy ! TY

Utterly mind blowing.

I could listen to this guy all day, everyday

Thy were smart , but also LUCKY .

It was the polish who did all the work in braking the code 🙄🙄🙄

A few relatives and I at a family reunion were talking about our experiences, and one fellow in his early nineties told us something unexpected - during WWII he was stationed in Washington DC in a group working on decrypting the Enigma machine. For secrecy reasons he couldn't and didn't divulge anything, but it was interesting to learn he had worked on such an important project. He's gone now, nevertheless I will never forget that little bit of exposure.

"Bomba" - a bomb in Slavic languages. I imagine someone asked a guy what he caries and to be secretive and keep inquisitive guy away he said "bomba".

Bletchly Park did not build the Bombe, it was a Computer Conservation Society project, supported by BCS. The Bombe is now at TNMOC.

Professor Brailsford is the David Attenborough of computing what an amazing gentleman!

The pattern on his jumper repeats every ninth line.

Nice film great story

Did they have to sacrifice innocents to not give away the fact that they broke the enigma code? Like in the movie?

All y0u ever hear about is Enigma, The Bombe, Collossus etc. No-one ever talks about what sort of message encryption the Allies used in their communications??

Excellent video, well explained. The mind boggles how a group of people can think up of a mchine like that that can work out the codes without computers, internet or calculators. There weren't half some clever folk back then
The worlds first digital programmable computer, a British invention
The Jet engine, a British invention
The world wide web, a British invention.

I can't find any information about the underwater cable mentioned at the end of the video and used to "submit" jobs to other machines running in the USA. It sounds really interesting.
