enigma do oriente baralho cigano - Uma visão geral
Após tua morte em 1843, ESTES segredos do Baralho Cigano desapareceram temporariamente, e somente cerca por 50 anos depois eles foram recuperados usando a descoberta do certos manuscritos deixados por ela.
Marian Rejewski quickly spotted the Germans' major procedural weaknesses of specifying a single indicator setting (Grundstellung) for all messages on a network for a day, and repeating the operator's chosen message key in the enciphered 6-letter indicator. Those procedural mistakes allowed Rejewski to decipher the message keys without knowing any of the machine's wirings. In the above example of DQYQQT being the enciphered indicator, it is known that the first letter D and the fourth letter Q represent the same letter, enciphered three positions apart in the scrambler sequence.
The Germans made it easy for the Poles in the beginning. The rotor order only changed every quarter, so the Poles would not have to search for the rotor order.

The relative ease of solving this network's settings was a product of plentiful cribs and frequent German operating mistakes.[136] Luftwaffe chief Hermann Göring was known to use it for trivial communications, including informing squadron commanders to make sure the pilots he was going to decorate had been properly deloused. Such messages became known as "Göring funnies" to the staff at Bletchley Park.[citation needed] Abwehr Enigma[edit]

Unfortunately the hotel gym wasn’t open, our room air con was not as powerful as it should have been, & the pool bar was a little on the pricey side which is why I’ve rated it an 8... However the bed was definitely one of the most comfortable I’ve stayed in! Free onsite parking was also a bonus. Overall a lovely, relaxing stay :)

The Kriegsmarine also improved the Enigma. On 1 February 1942, it started using the four-rotor Enigma.[186] The improved security meant that convoys pelo longer had as much information about the whereabouts of wolfpacks, and were therefore less able to avoid areas where they would be attacked. The increased success of wolfpack attacks following the strengthening of the encryption might have given the Germans a clue that the previous Enigma codes had been broken.
For machines where there was a choice of more rotors than there were slots for them, a rule on some networks stipulated that no rotor should be in the same slot in the scrambler as it had been for the immediately preceding configuration. This reduced the number of wheel orders that had to be tried.[96]
A major weakness of the system, however, was that no letter could be enciphered to itself. This meant that some possible solutions could quickly be eliminated because of the same letter appearing in the same place in both the ciphertext and the putative piece of plaintext.
In 1940 Dilly Knox wanted to establish whether the Italian Navy were still using the same system that he had cracked during the Spanish Civil War; he instructed tarot his assistants to use rodding to see whether the crib PERX (per being Italian for "for" and X being used to indicate a space between words) worked for the first part of the message.
The positions of the alphabet ring in relation to the core of each rotor in use (Ringstellung or "ring settings").
