Chapter 50 The Perfect Application of Twin Primes (Please Read!) "Aaaaaaaa!! Dad! I won't study if you take my computer away!" Lu Meng screamed in the room. Lu Peng directly put the computer into the Santana and prepared to send it to Lu Shan. "It's the second year of high school, a critical period. You said you bought the computer for study, but you were typing on the computer every day. I thought you were writing a paper, but you controlled the little people to dance, made some cartoon characters, twisted their waists or buttocks, and wore such revealing clothes." "You said you really danced in front of the computer and exercised, but your fingers were clacking on the keyboard. What's the point of practicing hand speed? Aren't you afraid of hand cramps?" "You are a minor, so you must have the awareness of a minor." "I have already told your brother Lu Shan." "I'll help you with math during the winter break!" "He's a top student. He's published a paper in a top journal at such a young age. Come on, be serious and study hard!" When it comes to his daughter, Lu Peng's emotions are relatively stable. When Lu Peng's wife Jiang Qin heard her daughter screaming, her head started aching and she couldn't help but blame her husband.
"What a fool! If you want your daughter to study hard, just let her study hard. Why did you dismantle her computer?" "Students should still combine work and rest. It's better to play games at home than to hang out with those questionable young men in Internet cafes!" Faced with his wife's reproach, Lu Peng would argue with her about the way of education. "You are making unlimited compromises, which is appeasement, surrender, and the cession of Manchuria! She will push further." Jiang Qin: "Okay, okay, you have a point. If you want to take the computer, then take it. Where are you going to move it to?!" Lu Peng was too lazy to explain so much. Jiang Qin didn't understand the business and technical issues. "Move it to Master Lu's son Lu Shan." Lu Meng, who was in the room, heard these words clearly and became even angrier. The computer was given to Lu Shan? Lu Shan also took math lessons for himself? Who on earth is this Lu Shan! …… "Ahem! I'm really sorry, Uncle Lu." Lu Shan couldn't help but grin when he saw the computer. "It's all as I should. I don't know much about computers, so I don't know if this is the configuration you want. If you need anything else, just tell me. I just want the equipment to be improved as soon as possible." "Thanks, Uncle Lu! My dad reinstalled the equipment this week, and I'll come paint the boards next week." Lu Shan was still quite soft-hearted and didn't tell me that I also needed a ThinkPad X61 laptop. With a computer, Poincare could learn knowledge faster, and Lu Shan no longer had to buy or borrow some regular books. Some papers can also be searched on CNKI, Wanfang, VIP, WOS, and Highwier. Lu Shan quickly went to activate broadband, but broadband in that era was still dial-up. Moreover, there was no Internet cable in the urban village, and after much persuasion, the manager of the telecommunications company finally agreed to pull a line from nearby. The internet fee is also extremely expensive, 80 yuan a month for 50G of data.
This amount of traffic should be enough for reading papers as long as you don't watch videos. But there is a problem that Lu Shan needs to verify in the Singularity Laboratory. That is if your home has broadband installed, an Internet cable, and your computer is also plugged into the Internet cable. So can the computers in Singularity Lab access the Internet? [Item list: desktop computer and accessories] [Consumption points: ] Gifts from others are good! They consume low points. [Enter the Singularity Laboratory, consume 2 points] [Remaining points ] Lu Shan was tinkering with the computer in the Qidian laboratory and soon finished assembling it. After plugging the computer's network cable into the laboratory's network interface, turn on the computer to connect. But I had trouble booting it up. There is actually a power-on password. In other words, Lu Peng got a computer from somewhere, and it is definitely not a new one, but it doesn’t matter, as long as it can be used. As for the power-on password, it is really easy to solve. For this kind of pirated system, Lu Shan has many ways to bypass the power-on password and enter the system. Including but not limited to through safe mode, PE mode or reinstalling the system, etc. After entering the computer, Lu Shan was a little confused. The desktop wallpaper is a portrait of a non-mainstream girl. This girl's features are somewhat similar to Lu Peng's. Lu Shan didn't know whether to laugh or cry. After all this time, Lu Peng had finally moved his poor-student daughter's computer over. After a simple test, it can be confirmed that the computer can access the Internet. This girl knew very little about computers and she filled up the entire C drive, while the remaining drives had very little content. Things stuffed into the C drive include but are not limited to chat software and various games, various photos of girls, etc. Of course, computers also have a bunch of viruses. Of course, Lu Shan is not a voyeur. He did not look at the girls' privacy. Except for applications such as games, he compressed all the girls' photos, documents, etc. into a folder and threw it into the D drive, and then reinstalled the system. While Lu Shan was tinkering with the computer, Poincare came over excitedly. He had learned about computers through many channels, but after seeing it for the first time, he still couldn't put it down. "I'm writing an analytical paper recently. It's so troublesome to write it with a pen. I've read a lot of tips. It's very fast to write papers with a computer. Oh, there should be a mathematical symbol editor in Office. I must have this thing, otherwise I can't write an analytical paper."
Lu Shan was shocked when he saw a pile of draft papers on the table. During this period, Poincare had completely figured out 2G communications. And they are very dissatisfied with the 2G communication model. In addition to being dissatisfied with its transmission speed, I am even more dissatisfied with its transmission structure and security. In Poincare's draft, he wrote: There are two standards for 2G networks, one is the European GSM standard, and the other is the American CDMA standard. No matter which mode it is, it is one-way authentication + plain text transmission... There are also a series of mathematical algorithms and formulas behind it. Lu Shan could understand this. In fact, one-way authentication + plain text transmission is not only a problem for 2G networks, but also for future 3G and 4G networks. It's just that they are better than 2G networks. This is also a loophole that many fake base stations can exploit to commit fraud. Then, Poincare's subsequent drafts became amazing. Poincare actually used some of the algorithms and logic of the twin prime conjecture that he had studied at the beginning, and used more rigorous large prime number multiplication operations to encrypt communication networks, and used this property to optimize some algorithms for network communication. Based on this starting point, Poincare had already written an analytical paper. Mathematics has never been a simple theory, but has its perfect application scenarios. Poincare handed the paper to Lu Shan and said, "Can you publish it so that relevant departments can use these methods to optimize the network?" Lu Shan felt upset. Could this paper be published earlier? After all, the world has adopted 3G network, and Xia Country's 3G will also be launched gradually this year. But when Lu Shan read the paper carefully, he made a surprising discovery. 感谢“third_EB”2张月票，“书友7745”2张月票，“书友8692”1张月票 Thank you for your recommendation votes!
