Open an aircraft carrier to fight against Japan

As soon as Yu Feng gave the order, the electronic warfare room sent a message: "Report to the commander, the encrypted code sent by the St. Lawrence River reconnaissance plane has too little information, and it may not be decipherable."

Yu Feng frowned, and said: "If you can't decipher it, you have to decipher it."

"Yes, we will try our best to decipher it." The electronic warfare cabin immediately started to decipher the code against time, but it is even more difficult to successfully decipher it, because the amount of information in this code is too small, only 65kb, encrypted The rules are brand new, and it can be said that there is no possibility of deciphering them at all.

After the St. Lawrence River reconnaissance plane sent this mysterious code, it changed its course and flew back to the Pearl Harbor Naval Base. The whole process took a very short time, without delay or hesitation.

Yu Feng felt that there was something wrong with this St. Lawrence River reconnaissance plane, so he ordered the fleet to slow down and let Lu Xue watch at the command post, and went to the electronic warfare cabin by himself.

As soon as Yu Feng came to the electronic warfare compartment, he felt a wave of heat coming over his face. Warships have always been called "a combination of spring, summer, autumn and winter". Some compartments must be kept at a low temperature, and some compartments cannot avoid high temperatures. This is the case for the electronic warfare compartment. , there are a lot of electronic equipment here, which emit a lot of heat when working.

In the code deciphering area, more than 30 codebreakers are working intensely, many of them are well-known mathematicians, after all, code deciphering is a mathematical problem in the final analysis.Everyone's face was covered with sweat. The amount of code information sent by the St. Lawrence River reconnaissance plane was too small, making it extremely difficult to decipher. Everyone was very nervous.

Seeing Yu Feng coming, Yang Ning, the leader of the code-breaking team, hurried over. Yang Ning is Zhang Yi's student, and he studied mathematics with Zhang Yi. Gao Feng went one step further, so he was "swept out". From then on, Yang Ning left pure mathematics research, specialized in applied mathematics, and later became the leader of the blue ocean ship's code-breaking team.

Yu Feng first said: "When will this code be deciphered?"

Yang Ning looked sad, and said sadly: "It's not a matter of time. This code has too little information, and I'm afraid it will never be deciphered."

Yu Feng frowned, his face was frighteningly gloomy, Yang Ning was Zhang Yi's disciple, his character was greatly influenced by Zhang Yi, carefree and unrestrained, seeing Yu Feng like this, he joked: "Commander, you don't have to be like this, No matter how angry you are, it's no use even if you throw me into the sea to feed the sharks..."

"I'm not angry..." Yu Feng smiled helplessly, Yang Ning laughed and said, "I don't think there is a need to decipher this code, maybe it was just sent by the US military to disturb our minds."

"Nonsense. The U.S. military sacrificed two St. Lawrence River reconnaissance planes to issue such a code. If it is just to disturb our minds, the price is too high, right?"

Yu Feng and Yang Ning were talking. Lu Xue, who accompanied Yu Feng, was idle and picked up the code sent by the St. Lawrence River reconnaissance plane. Print out the code, copy many copies, put it on the table, and everyone can look at it casually, maybe someone can find some clues.

Out of the corner of Yang Ning's eyes, he caught sight of Lu Xue. He snorted contemptuously, and said in a harsh voice, "Women, don't move things around."

Lu Xue's face flushed red, and she said angrily, "What did you say?"

Yang Ning walked up to Lu Xue in two steps, tore off the code in her hand, and said coldly: "What do women know, don't look around."

Yu Feng felt strange on the side, thinking to himself that Yang Ning is not a macho guy, he is usually quite gentle with little girls, what's wrong today?Why is this only for Lu Xue?

Yu Feng is a middle-aged man in his 40s, well-informed and well-versed in the world. He thought for a while, and suddenly thought: This Yang Ning is like this today, I am afraid he wants to attract Lu Xue's attention...

Lu Xue snorted and said angrily, "I originally wanted to help you, but since you have this kind of attitude, well, I won't help you."

After Lu Xue finished speaking, she turned around and left. Yang Ning sneaked up in front of Lu Xue and said with a smile, "How can you help us?"

"Get out of the way." Lu Xue reached out and pushed Yang Ning, "You look down on girls, so I don't want to help you."

"I was wrong, okay?" Yang Ning stood in front of Lu Xue again.

"I'm not going to tell you. Get out of the way." Lu Xue was about to push Yang Ning away again. When Yu Feng saw the two of them like this, he hurried over and said in a deep voice, "You two stop messing around, Lu Xue Comrade, if you really can help Yang Ning decipher the code, help him quickly."

"Then he has to apologize to me, why should he look down on girls." Lu Xue said angrily.

"I'll treat you to dinner later, okay?" Yang Ning said with a smirk, and Lu Xue realized that Yang Ning provoked her because she wanted to have dinner with her. : "Can I decipher this code?"

"So many mathematicians can't decipher this code, how can you decipher it?" Yu Feng asked in surprise, Yang Ning also spoke from the side, and said: "You are just an engineer, and your math level is a hundred thousand behind ours. Eight thousand miles, we can't decipher it, how can you decipher it?"

Seeing Yang Ning, Lu Xue intentionally made herself angry again, gave him a blank look, ignored him, and said to Yu Feng, "Because the code sent by the St. Lawrence River reconnaissance plane uses our own encryption rules."

"What do you mean?" Yu Feng and Yang Ning asked in unison, both of them were confused.

Lu Xue lowered her voice and explained: "In cryptography, the code is called 'ciphertext', and the content represented by the code is called 'plaintext'. The rules for converting plaintext and ciphertext are encryption rules. The encryption of this code The rules are used by our scientific research system, and people in your military system should have never seen this kind of encryption rules."

Yang Ning asked in surprise: "Why are the encryption rules used by your scientific research system known to the Americans?"

Yu Feng took advantage of the situation and asked: "Why did the Americans use the encryption rules of your scientific research system to send us such a code?"
