Chapter 252: Unbelievable! Start an academic seminar right away! Lu Shan explained it in plain words: "If the underlying logic of the program is too similar to others, or if you move it over and change it, it's like living in someone else's house. Changing some features is like decorating the house, which only changes the surface, but the structure of the house remains unchanged. Then others will know where the load-bearing wall of the house is and where the weak point is. This is the backdoor of the program, and they can find a way to break through it. Only by rebuilding the program can we be safe. Only you know the weaknesses of the house you built yourself. " Zhu Yajie nodded frequently and showed an approving look, which made the logistics director Gou Siyuan anxious. Didn’t we agree to conduct research and analysis? Why did the principal nod now? Now that the principal has nodded, the matter is mostly settled! "Principal, 306's technology has been certified by the industry. They have won awards in the International Internet Security Competition. Hackers cannot break through 306's firewall. There must be no technical problems! Moreover, 306 was included in the procurement scope only after passing the bidding." Gou Siyuan immediately retorted. Zhu Yajie looked at him: "Director Gou, do you have anything else to say?" There is no saltiness in this sound. Gou Siyuan immediately sorted out the words: "There is indeed a gap between the levels of domestic and foreign network security companies, but the Xia people should look for domestic security companies. We also have to give these national companies some opportunities to let them grow as soon as possible. It is also our responsibility to support national industries. In addition, although I don’t know much about firewalls, a house can not only be decorated, but also reinforced, turning weaknesses into impenetrable strengths, so that security is guaranteed. 306 Company has its own technical team, and has been working on solving relevant problems. We must have confidence in 306. If we don’t choose our own company, do we have to leave security to foreigners? " Wow, a big hat was put on everyone's head. Anyone who disagrees is considered unpatriotic? This operation instantly made everyone feel unhappy, but Gou Siyuan didn't care at all.
What's the point of caring about this? Others being angry with you won't hurt you, and the most important thing is that you can get tangible benefits. If you tell them about it, they will be so envious that they won't even have time to react. It is not difficult to guess why Gou Siyuan strongly supports 306. First of all, the 306 is indeed not bad. It is one of the best in China. Normally, people would choose it, even if it is a bit more expensive. But even so, two million is still too much for a laboratory, so this is Gou Siyuan’s second reason, he took kickbacks! Jiangzhou University is a big project. If it is successful, the total amount will not be low, but the average amount will not be high either. But Gou Siyuan took a part of it, which caused the price to be higher. Li Bo had some concerns before and told Gou Siyuan that it was not that they could not afford the kickbacks, but that if the price was too high, the project might not be completed. Gou Siyuan patted his chest and assured that he would definitely be able to convince the school. People like Li Bo naturally said that if he couldn't get it done, he would definitely lower the price, and then he couldn't consider the conditions with Gou Siyuan. Gou Siyuan also agreed to this, but both sides thought more. Li Bo was ready to use this matter to threaten Gou Siyuan, and Gou Siyuan was also ready to find another security company to get kickbacks. As for the kickbacks? There is no contract, no substantive evidence, so who is afraid of whom? Who in logistics and procurement is not suspected? Reputation is almost nothing. Zhu Yajie was somewhat displeased by Gou Siyuan's move, but he did not lose his temper. Instead, he announced that the matter needed further investigation and the meeting was adjourned. It was no use for Gou Siyuan to be anxious, he could only leave in frustration. That night, Li Bo was invited out for dinner by Gou Siyuan, and the purpose was self-evident. After three rounds of wine and five dishes, Li Bo turned off his phone and threw it aside to show his sincerity. This restaurant was also specifically recommended by Gou Siyuan, and he did it for privacy reasons, everyone understood. "Director Gou, did the meeting go smoothly today?" Li Bo poured Gou Siyuan a glass of wine and asked carefully. Gou Siyuan drank it and waved his hands in frustration: "Don't mention it! A good thing was ruined by a student." "Students? What kind of students can be involved in such a big thing?" Li Bo didn't understand anything.
"You don't know, this student is not ordinary..." Gou Siyuan told Li Bo everything he knew about Lu Shan. The more Li Bo listened, the more shocked he was. Is this really the level that a student can reach? I’m afraid it’s the God of Literature who has descended to earth. However, Li Bo still has confidence in 306: "It doesn't matter if this student has other opinions. After all, 306 has no rivals in China. What's the point of Lu Shan's opposition? He can't come up with a protection system! In the end, we still have to rely on 306 Company to build a security system." 306 has been developing for so many years, and has so many high-end talents working in the industry for so long. It has carved out a path among a bunch of antivirus software companies and has trampled on Mou Shan, Mou Xing, and Mou Ski. Li Bo does have the confidence to say this. What is the most feared thing in the cybersecurity industry? What I fear most is that some former rogue companies will transform into security companies. After the meeting, Chen Qiyi also found Lu Shan to ask the reason for his opposition, because 306 is indeed excellent, and even if it is a little more expensive, it is worth the money. After all, it is impossible to ask a foreign company to be responsible for the school's network security issues. “I just think we have the capability to take charge of our own cybersecurity.” "Oh? Have you found a trustworthy security company?" "No." "Then did you find a team that made a major breakthrough?" "Not at all." "That……" "I have solved the Landau-Siegel zero-point problem and started to explore the Riemann hypothesis. Although I have not yet broken through the Riemann hypothesis, I can come up with a safe fire prevention mechanism by figuring out the mathematical logic based on the zero-point problem." Lu Shan said calmly, and Chen Qiyi almost forgot to breathe while listening. Chen Qiyi was sure that he was not so old that his hearing was bad, and even less so that he would hear other words as Landau-Siegel zero problem. "Have you really solved the zero-point problem? What about the paper? How is it going?" Chen Qiyi's voice began to tremble. "The paper is ready. I'll send it to you if you want." "No! Don't send it out, print it out first! Make a backup of your computer and be clear about the time!" "We have already done." Chen Qiyi breathed a sigh of relief. He was afraid that someone would want to plagiarize Lu Shan's paper again. Now that the bad guy Tan Ming had started the conversation, Chen Qiyi felt that he could no longer trust anyone. "Then go back and send me a copy!" "Okay, please check it for me, teacher." Chen Qiyi couldn't wait to sit in front of the computer. Lu Shan quickly sent the paper to him, and then Chen Qiyi spent several hours reading it. After reading it, he fell silent. Chen Qiyi was not sure whether Lu Shan's things were accurate or not. At least he saw no problem with the process, and he could not find any loopholes in the logic. The set conditions and the derived conclusions all match. But just because you can’t see the problem doesn’t mean there is really no problem. It may just be that you have overlooked other conditions. Therefore, Chen Qiyi hopes to hold an academic conference for everyone to discuss it, but Lu Shan must agree. Lu Shan readily agreed to give an academic report, and Chen Qiyi couldn't wait to set the date for two days later. The entire meeting had to be kept strictly confidential, and no electronic devices were allowed to be brought in. They even got a set of testing equipment. Lu Shan stood on the podium and began his lecture with ease. "This paper essentially proves that the Landau-Siegel zeros do not exist. The original definition of the Dirichlet L function, L(s,χ), is this: The numerator is the value of χ(n), and the denominator is n raised to the power of s. At this point, we only consider the case where s is a real number, that is, when s=1, it is not equal to 0. So when s<1, that is, it is slightly smaller than 1, is it possible that it is equal to 0? ..."
A classic question, a classic beginning. The difference is that Lu Shan’s argument is very tortuous. Many conditions are added after being inferred to be true, and then the zero-point problem itself is deduced. This process is very similar to setting up a secure network firewall, both of which involve setting a large number of conditions to prevent the opponent from making inferences while ensuring your own safety. The academic paper was presented very quickly, finishing in just over an hour. After that, the discussion began, and the mathematics professors asked different questions, trying to resolve the doubts in their minds. "Let's say there is an even number N (a relatively large even number), and we use ρ(n) to define the characteristic function of this prime number, which is defined on positive integers. If n is a prime number, ρ(n) is equal to 1, and if n is not a prime number, ρ(n) is equal to 0. What do we say this sequence will look like?" "Generally speaking, it may be equal to 1 or 0" "But could it be negative?" "Obviously, if ρ(n) is negative, it must be equal to -1, and the necessary and sufficient condition for it to be negative is that ρ(n) and ρ(Nn) are both prime numbers. Only then can χn be negative, exactly equal to -1." Lu Shan was not flustered at all. He continued to explain. "N is always equal to n+(Nn), that is, N is a prime number plus another prime number. In this sequence (1＜n＜N), if there is a χn that is less than 0, then the necessary and sufficient condition is that N is the sum of two prime numbers." "Mr. Lu Shan, how do you prove that a certain χn is less than 0?" "We can give a very simple number sequence, even if it contains 10000 numbers, and we can write down whether there is a negative number among them. But N is very large, and if we want to define this thing as equal to 0, it includes the Goldbach conjecture and the study of weak results on twin primes, which needs to be discussed separately. " "Student Lu Shan, your paper involves a lot of problems related to the distribution of arithmetic series." "Yes! In a separate sense, my work, in the problem of arithmetic series distribution, should be the first to break through the limit of exponent equal to 1/2, that is, the exponent can be taken to be a little larger than 1/2. But the zn I used was basically the one they introduced. Later, I introduced a new Zn, and was able to prove the weak form of the twin primes. In the end, they all came down to this inequality.
