My German Empire

"Crown Temple."

Hydie. Raima sound is soft and crispy, as if you can hear a crisp.

"Miss Heili, how is the research project research?" The Janick single knife straight into the subject. If another man may come to a flower saying first, sweet words try to win women's goodness; but you can save these steps in his current identity, as long as he thinks, there will be a large group of women to compete with him, maybe the length Can be around the earth.

Heti smiled. "With the current progress to the end of the year, you can enter the practical phase."

"It's great." Jarni was tricky in the absence of the waiter, and brought a glass of champagne to Hydie. "That is to say, from next year, our communications will become a black hole that the enemy can't bear!" Compared with fixed frequency communications, the frequency hopping communication is also difficult to intercepted. As long as the other party does not clear the rules of the carrier frequency, it is difficult to intercept our communication content.

Hydie's face is somewhat unnatural. "His Royal Highness, you know that the practical is not equal to popularity. I am afraid that it is a bit boring to the department level."

"..." Yatik depressed mouth. "That is to say, the grass layer is still available to the Ennygema secret code."

Friends who have seen American "U-571" know that "Enny" cryptographic machine is the secret secret of the union of the allied countries in the war. It is the key to defeating the German naval submarine. History is also true, for submarine combat, especially the German Navy's "Wolf" tactics, radio communication is the most important means of submarine at sea activities, and obtain information notification, and "Enny" cryptography It is an apparatus for the entire radio communication security, and its importance is imagined.

The "Enny Gemma" cryptographic machine appeared in the movie, and the box is full of complex and exquisite components, the thick look and the typewriter have a bit similar.

It uses a complex letter to replace the encryption method, using a keyboard, rotor, jumper, reflector, and a display to symmetrically encrypt / decrypt. When you press any letter on the keyboard, the letter will be converted to another letter through the keyboard-rotor-jumper-reflector-display.

For example, when the first type is typed, the bulb B is bright, the rotor rotates, and the password corresponding to each letter will change. When you type a second time, the letter it corresponds to c; similarly, when you type A, it is possible to be bright. - This is the key to "Enny Gemma" is difficult to be deciphered, this is not a simple replacement password. When the same letter can be replaced by different letters, the same letter in different locations in the ciphertext can also represent the different letters in the clear, and the alphabetical frequency analysis is unused here. This encryption method is called "duplex replacement password" in password studies.

Ennygemma is an encryption method of algorithm and key separation, and the difficulty of cracking En Nigma is not to know the current key, including the initial position and jumper settings of the rotor. During daily use, Enny Mima's configuration can be encrypted by password, agreed with the previous day.

The Germans evaluated the use of the "Enny" cryptographic machine, and it is considered that the cryptography is easy to carry, and it is easy to use. For the enemy, even if you have a cryptographic machine, if you can't grasp the key composed of the three defense lines, you cannot deciphe. Erich, the highest commander of Germany, Erich, Virgibell, believes that "Enny Gema" will be the most perfect communication device for the German Defense Forces.

Therefore, to the German commander, the land of the San Air, all of the "Ennigma" is used as the standard system. - The Germans have reason to think that they have mastered the world's most advanced and safest communication encryption system, which is a password system that cannot be deciphered.

However, so stupidly send a letter to the machine,

The first thing to solve En Nigma is Polish, they want to get a commercial Enny Machi (usually used by the commercial Nicm Machine to be used by military, the Germans is really confident to their own encryption technology) Two Polish mathematicians led a batch of assistants for several years, and finally successfully decipher the 75% of the "Enny" cryptos.

However, the German military has improved "Enny Mima", an increase to 5 rotors, and the Polish is not able to overcome the new "Ennigma" machine for Germans until the Second World War.

The Polase Polish Intelligence Office knows that Poland is definitely falling. In order to resist this common business in Germany, they decided to give their "Ennigma" password together with relevant research materials to the British and France, will defeat Hitler hopes in Europe. These two major powers are on.

The UK provides the programs provided by Poland, and even in order to expand the password team for information security.

From the 40th house from the previous Cryptography Bureau to Brychelli Park, the area was extended by several times; the staff was amplified from more than 20 years to more than 9,000 people.

At the same time, the structure of employees also varies. It is mainly a linguist, and the main force is a mathematician. A large number of recruiting mathematicians, this is the British special British.

After that, everyone knows, Allen. Tu Ling although admired the Poles's wisdom, he realized that the Poles's cracking method relied on the vulnerability of Germans, and later the German upgrade Engel Machine, this crack method The failure. So Tuling pursues a more direct violent crack method: the machine counter the machine. If the Polish is the use of the vulnerabilities on the enemy's defense for the paratrooper, then the picture is even more like a positive confrontation of the infantry division. The password monster created by the machine, only the machine can overcome. Human tasks are just the working principle of designing machines and optimizing the amount of operations to be made by the machine.

On March 14, 40, the first Tuling "bomb" is put into use in the Blackge Manor. Soon, it successfully deciphered the first Ennigma secret code. Winteburns said when I sent this information to the Air Force's Director Machest, "Since then, the German's top secret information is completely a book that can be read." "

The Ennigma secret code has gradually become the most killing blade in the hands of the British. In the subsequent Alaman Battle, capture Sicily, Normandy landing, etc., the British and Allies have mastered the warfield initiative by breaking En Nigma, making the winning and negative balance gradually biased toward the Allies. One.

Of course, Of course, I won't repeat this stupid mist, although Allen. Tuling is now in Germany, but he does not guarantee that the British will not have other people to crack the Enn Gemma tag, so he wants to find a law. Improve the Nicm Machine and increase the difficulty of crack.

Hydie asked. "His Royal Highness, I have completed the task?"

Jenik laughed. "Of course, you have done very well, I naturally don't have a good message. However, this movie scene will be very grand, it is impossible to start shooting at this time, so I have to wait until the end of the war."
