Multiplying 17, by the six possible wheel orders gives , different ways that the scrambler can be set up. Although , is a large number,  it does not guarantee security.
A brute-force attack is possible: one could imagine using code clerks who each tried to decode a message using distinct rotor settings.
The Poles developed card catalogs so they could easily find rotor positions; Britain built " EINS " a common German word, meaning the number one catalogs.
Less intensive methods were also possible. If all message traffic for a day used the same rotor starting position, then frequency analysis for each position could recover the polyalphabetic substitutions.
If different rotor starting positions were used, then overlapping portions of a message could be found using the index of coincidence.
The German military knew the Enigma was weak. In , the German army introduced an additional security feature, a plugboard Steckerbrett in German; each plug is a Stecker , and the British cryptologists also used the word that further scrambled the letters.
The Enigma encryption is a self-inverse function, meaning that it substitutes letters reciprocally: if A is transformed into R , then R is transformed into A.
The plugboard transformation maintained the self-inverse quality, but the plugboard wiring, unlike the rotor positions, does not change during the encryption.
This regularity was exploited by Welchman's "diagonal board" enhancement to the bombe, which vastly increased its efficiency.
An important feature of the machine from a cryptanalyst's point of view, and indeed Enigma's Achilles' heel , was that the reflector in the scrambler prevented a letter from being enciphered as itself.
Any putative solution that gave, for any location, the same letter in the proposed plaintext and the ciphertext could therefore be eliminated.
By January , additional rotors had been introduced so that three rotors were chosen from a set of five hence there were now 60 possible wheel orders for the army and air force Enigmas, and three out of eight making possible wheel orders for the navy machines.
In addition, ten leads were used on the plugboard, leaving only six letters unsteckered. This meant that the air force and army Enigmas could be set up in 1.
In the German navy introduced a version of Enigma with a rotatable reflector the M4 or Four-rotor Enigma for communicating with its U-boats.
This could be set up in 1. By late a change in German Navy fortunes in the Battle of the Atlantic , combined with intelligence reports, convinced Admiral Karl Dönitz that the Allies were able to read the German Navy's coded communications, and a fourth rotor with unknown wiring was added to German Navy Enigmas used for U-boat communications, producing the Triton system, [ dubious — discuss ] known at Bletchley Park as Shark.
The Triton was designed in such a way that it remained compatible with three-rotor machines when necessary: one of the extra 'fourth' rotors, the 'beta', was designed so that when it was paired with the thin 'B' reflector, and the rotor and ring were set to 'A', the pair acted as a 'B' reflector coupled with three rotors.
Fortunately for the Allies, in December , before the machine went into official service, a submarine accidentally sent a message with the fourth rotor in the wrong position, and then retransmitted the message with the rotor in the correct position to emulate the three-rotor machine.
In February the change in the number of rotors used became official, and the Allies' ability to read German submarines' messages ceased until a snatch from a captured U-boat revealed not only the four-rotor machine's ability to emulate a three-rotor machine, but also that the fourth rotor did not move during a message.
This along with the aforementioned retransmission eventually allowed the code breakers to figure out the wiring of both the 'beta' and 'gamma' fourth rotors.
The first half of was the " Second Happy Time " for the German U-boats, with renewed success in attacking Allied shipping.
This was due to the security of the new Enigma and the Germans' ability to read Allied convoy messages sent in Naval Cipher No. In May the US began using the convoy system and requiring a blackout of coastal cities so that ships would not be silhouetted against their lights, but this yielded only slightly improved security for Allied shipping.
The Allies' failure to change their cipher for three months, together with the fact that Allied messages never contained any raw Enigma decrypts or even mentioned that they were decrypting messages , helped convince the Germans that their messages were secure.
Conversely, the Allies learned that the Germans had broken the naval cipher almost immediately from Enigma decrypts, but lost many ships due to the delay in changing the cipher.
The following settings of the Enigma machine must be discovered to decipher German military Enigma messages. Once these are known, all the messages for that network for that day or pair of days in the case of the German navy could be decrypted.
The bombe identified possible initial positions of the rotor cores and the stecker partner of a specified letter for a set of wheel orders.
Manual techniques were then used to complete the decryption process. The bombe was an electro-mechanical device that replicated the action of several Enigma machines wired together.
A standard German Enigma employed, at any one time, a set of three rotors , each of which could be set in any of 26 positions. The standard British bombe contained 36 Enigma equivalents, each with three drums wired to produce the same scrambling effect as the Enigma rotors.
A bombe could run two or three jobs simultaneously. Each job would have a menu that had to be run against a number of different wheel orders.
If the menu contained 12 or fewer letters, three different wheel orders could be run on one bombe; if more than 12 letters, only two. In order to simulate Enigma rotors, each rotor drum of the bombe had two complete sets of contacts, one for input towards the reflector and the other for output from the reflector, so that the reflected signal could pass back through a separate set of contacts.
Each drum had wire brushes, which made contact with the plate onto which they were loaded. The brushes and the corresponding set of contacts on the plate were arranged in four concentric circles of The outer pair of circles input and output were equivalent to the current in an Enigma passing in one direction through the scrambler, and the inner pair equivalent to the current flowing in the opposite direction.
The interconnections within the drums between the two sets of input and output contacts were both identical to those of the relevant Enigma rotor.
From there, the circuit continued to a plugboard located on the left-hand end panel, which was wired to imitate an Enigma reflector and then back through the outer pair of contacts.
At each end of the "double-ended Enigma", there were sockets on the back of the machine, into which way cables could be plugged. The bombe drums were arranged with the top one of the three simulating the left-hand rotor of the Enigma scrambler, the middle one the middle rotor, and the bottom one the right-hand rotor.
The top drums were all driven in synchrony by an electric motor. At each position of the rotors, an electric current would or would not flow in each of the 26 wires, and this would be tested in the bombe's comparator unit.
For a large number of positions, the test would lead to a logical contradiction , ruling out that setting. If the test did not lead to a contradiction, the machine would stop.
The operator would record the candidate solution by reading the positions of the indicator drums and the indicator unit on the Bombe's right-hand end panel.
The operator then restarted the run. The candidate solutions, stops as they were called, were processed further to eliminate as many false stops as possible.
Typically, there were many false bombe stops before the correct one was found. The candidate solutions for the set of wheel orders were subject to extensive further cryptanalytical work.
This progressively eliminated the false stops, built up the set of plugboard connections and established the positions of the rotor alphabet rings. A bombe run involved a cryptanalyst first obtaining a crib — a section of plaintext that was thought to correspond to the ciphertext.
Finding cribs was not at all straightforward; it required considerable familiarity with German military jargon and the communication habits of the operators.
However, the codebreakers were aided by the fact that the Enigma would never encrypt a letter to itself. This helped in testing a possible crib against the ciphertext, as it could rule out a number of cribs and positions, where the same letter occurred in the same position in both the plaintext and the ciphertext.
This was termed a crash at Bletchley Park. Once a suitable crib had been decided upon, the cryptanalyst would produce a menu for wiring up the bombe to test the crib against the ciphertext.
The following is a simplified explanation of the process of constructing a menu. The letters of the crib and the ciphertext were compared to establish pairings between the ciphertext and the crib plaintext.
These were then graphed as in the diagram. It should be borne in mind that the relationships are reciprocal so that A in the plaintext associated with W in the ciphertext is the same as W in the plaintext associated with A in the ciphertext.
At position 1 of the plaintext-ciphertext comparison, the letter A is associated with W , but A is also associated with P at position 4, K at position 7 and T at position Building up these relationships into such a diagram provided the menu from which the bombe connections and drum start positions would be set up.
The more loops in the menu, the more candidate rotor settings the bombe could reject, and hence the fewer false stops. Alan Turing conducted a very substantial analysis without any electronic aids to estimate how many bombe stops would be expected according to the number of letters in the menu and the number of loops.
Some of his results are given in the following table. It threatened further attacks on non-Muslim celebrities in Germany unless the demands are met.
Unlike previous video claims of responsibility, the letters directly addressed the German chancellor and had no religious justifications, ISIS logo, or signature.
Another claim was posted on the left-wing, open-publishing website IndyMedia. Initially there were claims that the Borussia Dortmund supporter's groups were infiltrated by neo-Nazi sympathizers which in the beginning, people believed could have led to the terrorist attacks.
It said the attack was committed because Borussia Dortmund did not do enough against racists and Nazis, who are believed to have some involvement in the club's supporter groups.
A few days later, a third claim of responsibility was sent to the newspaper Der Tagesspiegel , which hinted at a far-right motive.
The anonymous e-mail praised Adolf Hitler and attacked multiculturalism , adding that the attack was a "last warning". In the initial stage of the investigation, the police identified two suspects and arrested one of them.
The apartments of both suspects were searched for clues. On 21 April , the federal prosecutor announced that it had arrested a year-old German-Russian citizen, identified as Sergej Wenergold, on suspicion of fold attempted murder, bringing about an illegal detonation of explosives, and aggravated battery.
The man had been staying at the Borussia team hotel. He planted explosives along the road where the team bus would later leave to the stadium. During check-in, he chose a room with a window facing the road so he would be able to remotely trigger the explosion when the bus passed by.
Put warrants are derivatives that increase in value as the underlying security drops in price, a mechanism similar to short-selling.
The unusual transaction raised suspicion of money laundering with bank employees, prompting them to alert authorities and pass to them the identity of Wenergold, which led to his arrest.
Police also said the suspect left letters at the scene of the crime to frame Islamic terrorists for the attack.
Sergej Wenergold was charged with 28 counts of attempted murder for the attack. He admitted during the trial that he learned how to make the bomb on Google.
Bartra in the attack suffered a fractured wrist and had to spend five days in the hospital in the aftermath of the attack.
Sergej had tried to apologize to Bartra during the trial, however, Bartra would not acknowledge his attacker as he discussed how his life had been altered by the bombing of the team bus.
The match was postponed until the following day at local time UTC , which resulted in a 3—2 win for Monaco. However, Thomas Tuchel , the team's manager complained publicly that the decision was forced upon them.
There is a belief that this spat was the beginning of the end of Tuchel's tenure as manager of Borussia Dortmund, despite the team's victory in the DFB-Pokal at the end of the season.
