Chapter 56: Closing the net!
After multiple tests confirmed that the first generation of digital analogues was fully capable of handling all the encrypted messages that had been deciphered so far, programmers in the information building became busy again.
After all, it is still the first generation of digital models and programs used for experiments, and some things still need to be optimized.
But this has nothing to do with Xu Chuan. Like everyone in the math room, he has a bright smile on his face.
In the evening, Zhang Weiping pulled him to the small cafeteria of Sun Moon University. The small dining table was piled with various dishes, and Xu Chuan couldn't hold him back.
This is a separate treat that Zhang Weiping paid for out of his own pocket.
As for the information war, it is still too early to celebrate, at least until we use this mathematical model to catch those mice once.
At the small dining table, Zhang Weiping was already drunk. He kept Xu Chuan talking. One moment he asked him why he didn't come to study at Sun Moon University, and the other moment he asked him if he already knew the secrets behind those function problems.
Xu Chuan drank a few bottles of beer with him, and then listened to Zhang Weiping's story while eating.
During this period, he was probably the one who was under the greatest pressure in the mathematics room of the Information Security Department.
As a recent disciple of Mr. Chen, he led more than a dozen mathematics experts to study for nearly two months, but he was unable to solve the US encryption algorithm, which made many people doubt whether he really had the real skills.
The pressure of national information security, other people's doubts, and opponents' ridicule were all piled up in his heart, and they were almost becoming his heart problems.
Adults often collapse in an instant.
Although the first-generation digital analog has not been tested in actual combat, its 100% accuracy in deciphering past encrypted messages was enough for him to release the pressure in his heart.
A dinner lasted from about six o'clock to about nine o'clock in the evening. Finally, Zhang Weiping, who was unconscious, was taken back to the information building by Xu Chuan and handed over to a staff member who was standing guard.
After taking a bath, Xu Chuan also went to bed and went to sleep.
In fact, after completing the explanation of the simplified method to solve the Dirichlet function and the analysis of the rules behind the encrypted information a few days ago, he can leave.
After all, his later work had nothing to do with him, and he had been spending these days in the library of Sun Moon University.
But Xu Chuan wanted to see with his own eyes that Analog could break through the other party's latest encrypted message and catch a mouse, so he stayed.
And tomorrow is the time to verify the results in actual combat.
The next morning, Xu Chuan got up early without running. After washing, he went directly to the mathematics room, only to find that most people were already waiting here.
"Morning, Xu Chuan."
"Have you had breakfast, classmate Xu Chuan? I still have two buns here."
"I'll also give you a soy milk and a tea egg."
In the mathematics room, a group of people greeted him enthusiastically.
Ever since the math meeting that day, Xu Chuan had become accustomed to this scene.
After learning that Zhang Weiping's inspiration came from his manuscript paper, he seems to have become the group favorite, or mascot, of the Information Security Department's mathematics room.
A group of national treasure-level mathematics professors brought him breakfast, a treatment that few people have ever enjoyed.
At 10:07 in the morning, the door to the math room was pushed open, and a youth staff member ran in.
"Academician Zhang, these are the encrypted messages intercepted today, seventy-three in total."
The young staff member handed the sealed bag in his hand to Zhang Weiping. Zhang Weiping quickly took it, shouted to the people who had been waiting for a long time in the mathematics room, and handed out the encrypted message paper cards in his hand. "Everyone, work is coming!"
Different from usual, this time, the professors in the mathematics room swarmed forward and almost grabbed the encrypted message from Zhang Weiping.
Including Xu Chuan, he also received two encrypted messages.
After simple processing, everyone input the encrypted information in their hands into the computer.
The new generation of deciphering program that has been deployed on everyone's computer quickly started running. Pop-up windows indicated that the digital model was running, and the light from the display screen also reflected the expectant and nervous faces.
Time passed little by little, and the first encrypted message was decrypted.
“Decrypted successfully, but it’s a spam message!”
In the mathematics room, the professor who was the first to decipher the encrypted message stood up excitedly and shouted.
The excited voice stimulated the others, who glanced at the professor with envy. Everyone's eyes returned to the computer in front of them, looking forward to the completion of deciphering the encrypted message in their hands.
"I have completed the decryption here, and both messages are spam."
"Same here, two junk messages!"
Soon, the second, third, and fourth encrypted messages were perfectly decrypted by the computer, and the good news continued to be delivered in the mathematics room.
In the past, numerous spam text messages would have dampened everyone's morale again and again, making people discouraged and depressed.
But today, every junk text message appears, making people look forward to it.
In the mathematics room, Xu Chuan stared at the display screen in front of him. The news of successful deciphering that kept ringing around him made him swallow his saliva, looking forward to the successful decryption of the encrypted information in his hand.
Suddenly, the picture on the LCD screen jumped.
The bullet box that was being deciphered disappeared, and a familiar set of numbers made Xu Chuan's pupils dilate a lot as he was staring at the screen.
"Teacher Zhang, I found something here, which is digital coordinates."
Seeing this familiar set of numbers, Xu Chuan quickly stood up and shouted loudly.
Hearing the sound, the surrounding mathematics professors rushed over in droves.
"Hahahahaha, you are indeed our lucky star!"
"East longitude 111°36′ north latitude 40°57, this coordinate is Saibei City!"
"It's two twenty-five in the afternoon. It's now ten twelve in the morning. There are still four hours. I will inform Mr. Wu right now!"
After confirming that the deciphered information was the time coordinate, Zhang Weiping quickly ran towards the door, but before he could take a few steps, the door to the mathematics room was pushed open.
"No need to notify me, I'm coming!"
Wu Weiguo walked in quickly, quickly walked to Xu Chuan's seat, glanced at the computer screen, and shouted angrily:
"Son of a bitch, if you don't catch anyone this time, I'm going to smash up the General Administration!"
