Top 5 Weaknesses of an Enigma | Bletchley Park
Просмотров 87 тыс.4 месяца назад
During World War Two most military communications were sent via radio, but the enemy could listen in on those radio signals. In order to keep messages secret from the enemy you had to encipher them. Cipher machines like the Enigma were used by the German army and air force during the war to protect their radio messages. Join our Research Officer, Dr Thomas Cheetham, as he explores in-depth the ...
Enigma Variations - Modified Army & Air Force Enigma I
Просмотров 6354 месяца назад
There are many different models of Enigma machines, developed for different uses by different countries from the 1920s until the 1940s. The Modified Army and Air Force Enigma I was the most common model of Enigma in use by the Germans, but we know that this particular machine was captured and used by the Codebreakers at Bletchley Park. #BletchleyPark #WorldWar2 #SecondWorldWar #Communication #C...

    Seems to me the non-self-encipherment property could have been eliminated without making the machine more complicated, just by eliminating the reflector and only passing the signal through the rotors in one direction. But would that have had other undesirable effects on the security?

    • @thomaswalder4808
      @thomaswalder4808 Месяц назад

      Correct - the idea of the "reflector" and sending back the stream through the rotors was a very bad idea and even made the enigma more complicated to build Another design flaw was, that each rotor only had one notch for turning the next rotor one step further. This has the impact that the second rotor is moving only every 26th character and the third rotor only every 676th character. I think 99,9% of all messages were shorter than 676 characters so the third rotor never was moved. The later added fourth rotor would be only turned in a message longer than 17576 character. If somebody was able to send 3 characters per second using the morse code it would have taken 90 minutes to send such a long message. So from a cracking perspective the third and fourth rotor together with the sticker board could be treated as a "static" character substition which is is relativly easy to crack By adding more than one notch to each rotor it would be much harder

    Very interesting, how many permutations of the initial wiring could there have been? I am intrigued that the British didn't try the A-A, B-B one. Is it 26x26x26? I ask just because it is probably one of the easier challenges amongst very difficult ones. I can just imagine someone asking them in a meeting whether they had tried every permutation and them saying they had, even though they hadn't tried the one that few would think to try.

    • @thomaswalder4808
      @thomaswalder4808 Месяц назад

      The problem was not repeated characters but that enigma could never encrypt a character to itself. So if in the encrypted message at some position was an "E" you could be 100% sure that the clear text at that position could not be an "E". Knowing this the britains could guess a longer word which might be in the message and then find the positions in the decrypted text there this word might be. Without such a correct guess the "bombs" could not find out if they found a correct key. But luckily for the britains all messages of one day used the same key and some of this messages could be relativly easy guessed - like the weather reports. If you know the weather you could guess how the clear text of such a weather report was as it was send always in the same format.

      @@thomaswalder4808 Alright, so give me some rope here because I have fundamentally misunderstood the problem, because in my layman's head I would think that if you have an extra letter in the system that tells the operator to simply transmit the inputted letter as written in cleartext that it would solve this problem. As a hypothetical example, I write down BLUE on the machine and B comes out X, L as C and then the machine tells me to write U and then it goes back to conventional encryption as E comes as D. I my head, while admittedly probably opening up other avenues of decryption, should solve the problem as described since you can no longer be certain that some of the letters have gone back on themselves.

    With stuff like the plugboard, you say it was a weaker than a more complex plugboard, but how much did it add over no plugboard? Likewise with the reflector, it was weaker than the more complex setup of dual paths through the rotors, but how much did it add over only going through the rotors once? Overall were any of these things so bad that it would have been more secure if they had left the feature out entirely?
