"Hahaha, you are worthy of being the number one deciphering genius in my confidential department. You can see the clues at a glance." Just when Major Mitsui was still puzzled after hearing Li Ningyu's words, Jin Shenghuo beside him couldn't help it.
He smiled.
However, Li Ningyu just smiled faintly and corrected: "I don't dare to take it seriously. In terms of the speed of deciphering, Director, you are much faster than me."
Jin Shenghuo lit a cigar for himself and said with a smile: "It's just a small skill, not worth mentioning."
Now Major Mitsui couldn't stand it any longer. He slammed the table and said angrily: "What on earth are you two talking about!?"
"It seems that Major Mitsui really knows nothing about translation! Section Chief Li, how about you explain it to him briefly?"
Jin Shenghuo was obviously very honest about Major Mitsui's attitude towards him just now, so he spoke very rudely, and Major Mitsui opposite him knew that Jin Shenghuo was clearly looking down on him as an outsider, but in front of so many people
It was hard to get angry, so he had to suppress his anger and turned to look at Li Ningyu.
"It's very simple, because it can't be solved. This complicated algorithm must be the German Enigma. If I remember correctly, this kind of cipher machine is owned by the Japanese Army and Navy, but it still
We have to organize business seminars to crack it, so I dare to conclude that this password must be encrypted by an improved version of this cipher machine, that is, the second generation Enigma machine. Without the Enigma machine, it can only be deciphered by hand.
, let alone two hours, not even two years!”
As soon as these words came out, everyone put down their pens in embarrassment, with awkward smiles on their faces as if they were just waking up from a dream.
At this moment, there was a sudden sound of clapping at the door, and then Colonel Morita walked in from the outside with a satisfied smile, "Thirteen minutes, I finally heard a satisfactory answer!"
At the same time, on the deck of the ship.
"How long do you want to keep checking? The seminar has already started! If it really delays the official business of the Japanese Army Intelligence Department, can you afford it?"
Seeing Wu Zhiguo's hands dangling deliberately and refusing to let him go, Gu Xiaomeng's daughter lost her temper and shouted in a high voice.
However, before he finished speaking, Wu Zhiguo came over and said with a smile: "Miss Gu, if I remember correctly, you should be the one who is late, right? My subordinates are just doing routine work and fulfilling their duties loyally. Is there any problem?
Besides, who asked you to wear casual clothes to attend a business seminar? Do you really think this is an outing? "
"You...you are deliberately making things difficult!"
Unexpectedly, after hearing this, Wu Zhiguo chuckled and said extremely arrogantly: "Yes, I am just making things difficult for you, how about it?"
"you!"
Just as he was talking, Wu Zhiguo suddenly rushed in front of Gu Xiaomeng, clamped a hand on her neck, and said viciously: "Don't think I can't see what you just wanted to do? Don't blame me for not warning you.
I won’t stop you from seeking your own death, but you must not involve others, do you understand?”
As Wu Zhiguo spoke, the strength in his hands gradually increased. After a while, Gu Xiaomeng's pretty face was already red from being suppressed.
"What are you...surnamed Wu...doing...what, let go..."
While Gu Xiaomeng was still struggling, Wu Zhiguo suddenly pressed against her ear and whispered quickly: "Your previous files in Shanghai have been destroyed. When you arrive at the conference room, Qian
Don't expose your relationship with Li Ningyu, do you hear me?"
Hearing this, Gu Xiaomeng's pupils trembled violently. What did Wu Zhiguo's words mean? Is it a test? Or...
In the blink of an eye, Wu Zhiguo let go of his hand and threw Gu Xiaomeng to the deck. He pointed at one of his subordinates and ordered: "Take her directly to the conference room and let the person named Jin take care of her."
Look, what kind of person did he try his best to transfer to the confidential room!"
"But Captain Wu, Colonel Morita is now..."
"I won't say it a second time, go! Or not?"
"You...please calm down, I...I'll go right away..." The man obviously understood Captain Wu's temper, and he quickly responded and pulled up Gu Xiaomeng, who was still lying on the deck, breathing heavily, and escorted her
Walking to the conference room...
Everyone in the conference room was surprised by Morita's sudden appearance, and at the same time they couldn't help but feel vaguely uneasy in their hearts.
But even so, everyone stood up immediately and watched him respectfully as he came to the throne.
"I've long heard that an ace codebreaker came to the Suppression Switchboard. He once deciphered the key secret messages for the assassination of Chairman Wang. The reason why the establishment of the Nanjing National Government was so smooth, Chief Li, you are indispensable!"
"Captain Morita, you are very grateful. I was just fulfilling my duties."
"Chief Li is proud but not arrogant. I admire this character very much." After saying this, Morita made a gesture to everyone to sit down.
After everyone sat down, he cleared his throat and said truthfully: "To be honest, as Section Chief Li just said, these secret messages in your hands are not ordinary messages, but the German Enigma. At the same time, they are not
A simple Enigma, but encrypted by a modified second-generation cipher machine. As for your real task today, it is not for you to decipher this message, but for you to decipher this message based on all the information intercepted by the empire in the past year or so.
From the secret code, the structure of Germany’s second-generation Enigma machine was deduced.”
Speaking of this, Morita gave Mitsui a look at the side. The latter immediately understood and lifted the black cloth covering the table behind everyone, and then a series of cryptographic machines with different structures were revealed in front of everyone.
.
"Everyone, please take a look. Here are the cipher machines of the four countries: the United States, Britain, France, and the Soviet Union. For your reference."
As soon as these words came out, there was a burst of whispers, but Li Ningyu stood up and left without saying a word.
"Stop!" Seeing Li Ningyu about to leave, Morita quickly stopped her, "Chief Li, what do you mean? In your opinion, with such a large number of references, it is still impossible to decipher this message?
"
"With all due respect, Colonel Morita, it's impossible with the few cipher machines you gave us!" Li Ningyu slowly turned around and said word by word.
"What's the reason?"
"In the 26th year of the Republic of China, after the Japanese and German allies signed an intelligence exchange agreement with the Soviet Union, the German military once presented several first-generation Enigma aircraft to Japan, which are still in use by the Japanese military headquarters today. I am right, Morita.
Colonel?"
"...That's right." Morita was silent for a moment, then said with a gloomy face, "Go on."
"Later, the German army modified the first-generation cipher machine to form the second-generation Enigma machine they are currently using. There were only three rotors in the first-generation Enigma machine, and each rotor would perform a replacement encryption on the input characters.
, after three replacement encryptions, the total number of password tables will reach more than 100,000. After the signal passes through the three rotors, it will also pass through the reflector and reversely pass through the three rotors for secondary encryption, and these rotors will also be linked.
The position changes with the input, causing the password table to change. In addition, before the keyboard signal is transmitted to the rotor, it will also pass through a terminal board. The specific wiring of the terminal board is also part of the key, which greatly increases the number of password tables.
In the 22nd year of the Republic of China, someone cracked the first-generation Enigma machine by making a replica. Germany was forced to add a new scrambling dial. Since then, there has been no news that the cipher machine has been cracked. As for Japan,
...On the original basis, purple was added..."
"Okay, Section Chief Li." Before Li Ningyu could finish speaking, Morita raised his hand and interrupted, "You don't need to go into detail. I just want to ask you one question, how can I decipher this message?
"
"Theoretically, without the Enigma machine, it would be impossible to decipher it simply by relying on manual brute force!"
However, before he finished speaking, Jin Shengxian on the opposite side couldn't help but said: "Chief Li, your words are too absolute, aren't you? As long as the encryption mode is replaced, it means that after different characters are replaced, the input result
It will not be itself, so as long as the probability of different letters appearing is counted and the German linguistics statistical model is used for calculation, the substitution law of the Enigma machine can also be deduced, as long as the intercepted code is long enough..."
Halfway through the words, Jin Shengxian's voice suddenly stopped, and then he frowned. He took out the metal pill box he carried with him in embarrassment and took an antihypertensive pill, which barely suppressed the blood pressure that had just soared.
Go down.
Li Ningyu said with a hint of ridicule: "It seems that you have finally discovered it, Professor Jin. I admit that what you just said is correct, but that is also a theoretical cracking method. If you follow this method, then please do the math.
How long does the intercepted code have to be to be able to calculate the patterns of hundreds of millions or even billions of code pads? And to be able to decipher the information key?"
A few words left the Jin Shengxian speechless, while Li Ningyu continued to talk to himself: "So, if Colonel Morita wants to crack the second-generation Enigma machine in a short time, the only way
The feasible solution is to take out the first-generation cipher machines, including Purple Secret, for our reference and modification, so that we can complete the replica machine."
Hearing this, everyone started talking again. After Morita coughed slightly to signal everyone to be quiet, he narrowed his eyes and said to Li Ningyu: "Chief Li, do you know what you are talking about? No matter whether it is the first generation or the second generation Enni.
The Gamma machine is currently our army's most reliable encryption method. Once exposed, our army's encryption system will be like a lion exposing its belly. I will never allow such a risk!"
"Deciphering is inherently risky! There is no need to pay a price for deciphering. Reducing the cipher machine based on the secret message is like drawing a chicken based on an egg. It is simply impossible! That's why I just wanted to quit. If Colonel
If you really want to crack the secret of the second-generation cipher machine, you must first expose the first-generation cipher machine to us."
However, before he finished speaking, Morita without saying a word, directly pulled out the pistol from his waist and slammed it on the table in front of him, which immediately startled the others.
"Chief Li, what you just said makes me suspect that you are a spy of the enemy, specially coming to spy on the secrets of the military's cipher machine."
As soon as these words came out, Major Mitsui on the side also pulled out his pistol and pointed it at Li Ningyu from behind, as if he would shoot without hesitation if Li Ningyu dared to act rashly.
"Chief Li, now you have three seconds to confess, who sent you here? Chongqing or Yan'an? Tell me!"
However, at this moment, the guard's voice suddenly came from the door, "Report!"
"Come in!" Although Morita was very unhappy at being suddenly disturbed, he still suppressed his anger and said.
"Report to Colonel, Colonel Gu Xiaomeng, a member of the Intelligence Department of the Suppression Headquarters, has no military discipline. He did not board the ship at the specified time to attend the meeting, and was still wearing casual clothes. Please tell me, Colonel!"
It's okay that Morita didn't listen. After hearing the guard's report, his face suddenly turned livid, "You want to report such a trivial matter to me? Get out of here!"
"yes!"
"Wait a minute!" Just when the guards were about to take Gu Xiaomeng out, they were stopped by Major Mitsui.
"Is there any problem?" Morita asked.
"Colonel, don't you feel that the three people in the confidential office today are strange?"
After hearing what Mitsui said, Morita suddenly realized something, and then turned his head and looked at Jin Shenghuo with suspicion.
"Colonel, please don't think too much, this must be a misunderstanding!"
Morita shook his head, "No, it's not a misunderstanding, it's a premeditation! These two people are your subordinates. One wants to expose the cipher machine, and the other is deliberately late in casual clothes in an attempt to evade boarding inspection. That's it.
With mutual cooperation, there is only one possibility, and that is the secret theft operation carefully planned by you, Director Jin! Lock up the three of them, report them to the headquarters, and let me personally interrogate them!"
"yes!"
"Wait a minute! Don't bother Colonel, I'll do the interrogation myself." After saying that, Jin Shenghuo walked straight to Gu Xiaomeng, pointed at Li Ningyu not far away and said, "Miss Gu, I want to ask who this is.
?What’s her name?”
As soon as these words came out, Gu Xiaomeng immediately recalled what Wu Zhiguo had just said, so she glanced at his finger and replied angrily: "How do I know? Who is she?"
Hearing this, a subtle smile appeared on Jin Shenghuo's face. He turned around and said to Morita: "Colonel, this lady just joined the job yesterday. The two of them have never met, so how can they cooperate with each other?"
Morita couldn't help but be stunned for a moment after hearing this, and then winked at Mitsui, who immediately understood and stepped forward to ask the guard for Gu Xiaomeng's military ID card. He checked it carefully, then leaned down and said softly: "
There is nothing wrong with the certificate, it was indeed issued not long ago and the seal on it is still fresh."
Although his voice was very soft, Jin Shenghuo easily guessed the content, "I, Jin, have been in the intelligence community for more than 20 years, right? If I really want to steal secrets, I will never know how to do it."
What do you think, Miss Gu, who is new to the industry, is so stupid to come to this occasion in such a blatant manner, Colonel Morita?"
