Chapter 222 Network Security and the Riemann Hypothesis Jiangzhou University's handling of Wang Yang was very simple. They simply said that he had violated work discipline and expelled him. Not a single extra word was added. As for where Wang Yang went after being fired, no one knew. But Wang Yang must have gone to a place where he could be sheltered from the wind and rain, where he had food and lodging and a regular schedule. Apart from not being able to contact people and not having freedom, there were no other disadvantages. Wang Yang lived a life of state support, while Tan Ming lived a life of superiority. After getting the latest information, his status rose rapidly. The new material is about how to excite electrons and speed up electronic circuits. This does not mean that the material requirements can really be reduced a lot, but it means that under the premise of the same material performance, this method can operate more efficiently. Topological semimetal semiconductor materials have strong performance and can withstand such tests. But you just need to change your mindset. As long as you don't care too much about the consumption, you can achieve the operating speed of BanSi's memory sticks, or even faster, even with slightly inferior materials. What a coincidence! This new information contains relevant information on how to improve the performance of existing materials. It is a mystery to those who have not experienced it, but for Tan Ming, it is a good thing that comes right to his doorstep! He has experienced many of the steps, and this is also what Tan Ming is most excited about.
"Hahahaha! Lu Shan, you used my method after all! My method is not that it cannot be worked out, but it is at a higher level! It is so forward-looking!" Tan Ming overwhelmed Lu Shan in academics, which was more satisfying than embezzling the one million Mi Dao. Tan Ming was like a polished copper kettle, standing on the podium again to teach the materials team of the University of Pennsylvania. With Lu Shan's help in organizing his ideas, Tan Ming's lectures became smoother and many loopholes were filled up. After the academic report, Lawrence even apologized to him: "Dear Mr. Tan Ming! I apologize to you. I originally thought that there was something wrong with your thinking. I didn't expect you to be so far-sighted. The products from Xia Country are backward products made with low-level thinking. As long as we follow your thinking, we can develop more advanced products!" "Professor Lawrence, you're welcome. Originally, this matter cannot be blamed on you. It was Lu Shan who collected all my information, which led to him finding a new method based on my work. But now it's good. We will be faster! Now we need the following equipment, you have to prepare it quickly." Tan Ming opened his mouth to emit strong laser pulses, and at the same time, he had to be able to emit weaker lasers with twice the frequency. The electron release under strong lasers is not controlled by a single photon, but by the laser electric field. Electrons enter the vacuum through the metal interface, and the superposition of the two light waves controls the shape and intensity of the laser field, thereby controlling the release of electrons. So we also need vacuum tubes, vacuum machines, super-strong current supply devices, and high-speed cameras... In short, there are a lot of things, each of which costs at least one million square meters, and some even have to be customized, which requires upgrading the existing processing level. Lawrence took a breath when he heard it. "Many of these devices are actually available at the University of Pennsylvania..." "It's useless! We need new ones. This is a brand new material that cannot be made with the original equipment! Don't worry about the money. We must have enough new insights into the electron release of solid metals and the quantum mechanics of the light fields used. This information can make you a double Nobel Prize winner in physics and chemistry!" Tan Ming continued to paint a rosy picture for Lawrence. Is Tan Ming really that confident? Actually, that's not necessarily true. He always doubts that his ideas are not good enough, and he still feels uneasy even after he has done some self-exploration. But this is not important. What is important is that he can continue to survive in the United States! If the idea is correct and the results are achieved quickly, Tan Ming may not be happy. He will be kicked out immediately because he has no value. He understands the hypocrisy and greed of white people. The best thing is to always contribute new things, but without any final results, so that the Americans are always hanging. The Americans quickly announced that they had made great progress in topological semimetal semiconductors, specifically, a new breakthrough in the electronic aspect. They have now started to manufacture new equipment for research, and the materials will soon be available. They also introduced how expensive and advanced the new equipment is. It's not that Americans are impatient, it's a need. Xia Country has developed new materials, and the United States is under great pressure. This means that the new academic heights are in Xia Country, which is intolerable for the arrogant white people who have been ahead for hundreds of years. Because according to their propaganda, Xia State was backward and ignorant, with social unrest, people being violent and the authorities being warlike. Such a country has no future at all. As a result, Xia country has produced epoch-making materials while the United States does not. This indirectly proves that Americans are no good. In order to save face, we naturally have to work hard on publicity.
Those who were involved in the Wang Yang incident at Jiangzhou University burst out laughing when they saw the US propaganda. "Tan Ming is really outstanding. He has led the Americans astray. These equipments are really expensive. We can't buy them even if we queue up." Hou Debang, dean of the School of Materials Science and Engineering, couldn't help but sigh. Zhu Yajie also touched his chin and was shocked: "For example, this multi-frequency laser transmitter is really out of market and strictly controlled. It took the whole Western industry chain to produce it. I didn't expect Tan Ming to be able to trick them into buying it." Lu Shan smiled and said, "It would be a waste of talent if Senior Tan Ming did not join the Strategic Research Institute. The United States will not only spend a lot of money this time, but also waste a lot of time." Everyone smiled knowingly. This is equivalent to the Americans abandoning their original technical route and taking Lushan's unique route, which is doomed to fail. If they don't follow, they will fall behind. Lushan's route is much cheaper than the US technical route, but the product performance is much better, so the Americans can only follow. In fact, there are many things that Lu Shan and the others cannot think of. In order to get these equipment, the University of Pennsylvania almost became a grandson of its sponsors. These sponsors include large companies and powerful alumni groups. American universities are basically sponsored by the government, and the government does not provide money. Whoever has more sponsors and more powerful alumni will have more impressive results, and their university will be ranked higher. Since it is a sponsorship system, making money becomes almost the only indicator. Lawrence patted his chest and assured everyone how much money this thing would make after it came out, and how everyone would share the profits. He spoke so eloquently and finally convinced the skeptical sponsors. Don't always say that there are no human relationships in the United States. That's all nonsense. Where there are people, there are rivers and lakes, and there are different social classes. Asking others for help is the same. I really don’t know what will happen to Lawrence and Tan Ming when the day comes when this project finally fails. Jiangzhou University took advantage of the Wang Yang incident to hold a meeting to promote reforms. Participants included experts, professors and leaders from the School of Materials, School of Science and School of Computer Science. Lu Shan was from the School of Science, so he naturally attended the meeting as well. The purpose of this meeting is not only to identify problems, but also to find solutions, otherwise these colleges would not have come together. At the meeting, Principal Zhu Yajie personally presided over the meeting and introduced the course of the incident. Everyone naturally knew what happened to Wang Yang. “Although there were certainly foreign forces involved in this incident, we should also learn from this incident the necessity of patriotism education and education on the principle of confidentiality. There are many talented people in universities. If these talents cannot be put on the right track, the damage they cause will be more serious than that caused by ordinary people. Starting today, everyone should strengthen relevant education, understand the dangers, understand the consequences, and nip it in the bud! " Zhu Yajie gave serious instructions at the meeting. Zhu Yajie then explored the incident from another angle: "From this incident, we also realized that if you fall behind, you will be beaten. Why are the security measures that we have spent a lot of time and money to upgrade so fragile? Is it because we can't do better or do we never think that this kind of thing will not happen to us? Our server was hacked by the US as soon as it was connected to the Internet. This actually shows that there is a huge gap in the level of the two sides. This requires everyone to work together. Now let Dean Zhou Wei explain it to us..." After Zhou Wei came up, he didn't say too many professional terms, but simply introduced the hacker attacks. Simply put, there are two types. One is a non-destructive attack, which uses a denial of service attack or information bomb to overload the system's processing capacity in order to disrupt the operation of the system but not steal data. The other is a destructive attack, which aims to invade other people's computer systems, steal confidential information from the system, and destroy the data of the target system. If we look at the specific means, there are even more, including attacks on information protocol vulnerabilities, remote manipulation, data-driven attacks, ICMP message attacks, and so on. "With so many methods, how can we protect ourselves? The essence is to lock the program and use encryption algorithms to prevent outsiders from attacking us. It's like installing a password lock on the room and letting the opponent guess the password. Commonly used symmetric data encryption algorithms include AES, DES, and 3DES. Asymmetric encryption algorithms include RSA, DSA, and ECC. There are also some linear hash algorithms, that is, signature algorithms, MD5, SHA1, and HMAC. The advantages and disadvantages of each algorithm are obvious, and it is difficult to say which one is good or bad. The key management of symmetric encryption algorithms is complex, so asymmetric encryption algorithms are used for small data.
The key of the symmetric encryption algorithm can be managed by an asymmetric encryption algorithm..." As he listened, Lu Shan couldn't help but think of the Riemann hypothesis. Many of its applications are in cryptography, which is also what Singularity Labs has been busy with recently. Turing is very concerned about this matter, almost to the point of madness. After the meeting, Zhou Wei walked with Chen Qiyi and Lu Shan. Zhou Wei jokingly said to Lu Shan, "If Lu Shan can prove the Riemann hypothesis, then our country's network security will far surpass that of the United States. At that time, we will no longer have to worry about hacker attacks from the United States." "You become less reliable as you get older!" Chen Qiyi patted Zhou Wei, "Don't put so much pressure on the child. He just solved a difficult math problem. Take a break!" "It's okay, teacher. I'm actually very interested in the Riemann hypothesis and have already done some preliminary research." Lu Shan was very serious. "Really? Tell me what you think!" Chen Qiyi's eyes lit up and he immediately became interested. Zhou Wei was very happy to see this situation, because today's meeting was said to be for several colleges, but in fact it was for Lu Shan! Among so many people, if there is anyone who can make Xia Country's Internet security far surpass that of the United States, Lu Shan's voice will definitely be the highest, otherwise Zhou Wei would not have mentioned Lu Shan here.
