Hammer of Technology

"First of all, the source code we got is not complete, it is only the core part, and the extended function part needs to be supplemented. Second, if the core code is not thoroughly researched, it may bring immeasurable technical risks if it is copied directly. Analyzing the code takes time .For example, we have seen many very special equations in the code. Simply put, these equations are a very special type of equations in structure, and they have fixed return values ​​after receiving specific signals."

"The existence of such equations can be understood as an algorithm testing phase to test the responsiveness of the algorithm. But it may also cause systemic risks."

"Then why don't we get rid of this type of equation?" Someone immediately asked.

"It's not so simple to remove. These equations are embedded in the main function. After removal, they may cause unmeasurable impact. The core code needs to be completed and tested repeatedly. And I'm just giving an example, we don't know Are there other risks in the code."

"Wait, if you say this, since there are known risk vulnerabilities, why can't we use them to attack the other party's equipment?" Another person found the loophole in the technical officer's words.

"This has to be explained mathematically, because the developer has a constant X, which is known to the developer but unknown to us. This is actually the same as RSA encryption, the difference is that except for the developer , No one has the private key in their hands! So now we found that the possible risk assessments are all based on similar situations.”

"You mean, the developer may have hidden a backdoor in the source code?" Someone asked with bright eyes.

"It can only be said that there is such a possibility, but there is no evidence. And there is a very interesting setting in the code, which is troublesome to describe in technical language. Simply put, this is a trigger, which is used to receive the authentication code. According to the description After authentication, the trigger will start working, and the system will restore according to some preset commands."

"Let's put it more simply. Even if those equations are really backdoor programs reserved by developers, in actual use, if they are certified as genuine, they may lose their original effectiveness. So it's hard to say that we can take advantage of this. to attack each other. Because using this technology to prevent infringement is a very complex but wonderful method. In fact, many of our engineers are very interested in this design." Kool Cowper replied.

"Okay, but half a year is still too long. Four months, Kool, you only have four months. After four months, I need a complete solution! Of course, if any department needs to cooperate during this period, everyone will Full cooperation, need any support, you can contact me at any time, I will coordinate. Tell me Kool, four months, okay?

"Yes! Mr. Cuttle!"

"In addition, continue to maintain contact with Huawei, and the price can be raised appropriately."

"Ok!"

"Dismiss!"

……

In fact, the Ericsson family is definitely not the only one holding the same idea.

For all network equipment service providers in the world, technical security has always been very important, which is why everyone invests heavily in technology research and development every year.

The more patent rights you have, the more voice you can have.

Only by maintaining the leading technology can we have a dominant position in the market competition.

For some new breakthrough technologies, before obtaining formal authorization, they must first have the ability to imitate in order to make people feel safe.

As for national patent laws...

Strong means intellectual property rights, weak means use.

As long as the market is maintained first, it is not a big deal for these giant multinational companies to spend several years in litigation.

Every year these multinational companies may fight several patent infringement lawsuits, sometimes as plaintiffs and sometimes as defendants.This is not news, sometimes you win, sometimes you lose, and sometimes you shake hands in the middle of the lawsuit...

In the most high-end competition, there are everyone, but there are no honest people.

So God knows how many engineers in the world have received the same task as Ericsson's CTO.

Imitation, improvement, and innovation pull everyone to the same starting line. Everyone continues to compete, and whoever lags behind will be out first.

And the injured are always the technicians fighting on the front line. After all, this kind of task is often the most difficult and hard work, which requires long-term use of the brain, so it is likely to lose hair due to excessive use of the brain or long-term anxiety.

Because if you don't do a good job, if something goes wrong, you may have to take the blame.

……

If Ning Wei knew this, he would probably be very honored.

Ah……

Lao Han is not fighting alone.

Hundreds or even thousands of senior programmers and algorithm engineers around the world will face his shit-laced code day and night in the next few months. Excited to explode.

There are thousands of bald heads with high IQ in the field. When he goes to participate in similar international conferences in the future, won't he be able to stand out with his lush hair?

But Ning Wei couldn't care less about these things at this time.

Because he was already standing outside the International Mathematics Research Center building of Yanbei University.

Just now Lu Dongyi took him to the hotel in the school to settle down first, and now he is taking him to see his tutor.

This is not the first time he has been here, but he is still a little nervous.

When he came last time, his default mentor went abroad to attend a meeting, so he couldn't meet him, but this time, Tian Yan was really waiting for him in the office.Although he had never met this mentor, Lu Dongyi had mentioned it to him quite a few times.

It can be said that they have been friends for a long time, and Ning Wei feels very strict.

"Is Director Tian easy to deal with? I released Director Tian for a year, so he should scold me if he doesn't meet me?" Ning Wei asked.

"Heh... what do you think?" Lu Dongyi sneered.

"I'm not afraid of scolding me. The professors of Jiang University told me that if Director Tian dares to scold me, I will threaten him to change the tutor." Ning Wei said seriously.

"I……"

Lu Dongyi suddenly realized that he had nothing to say, um, the younger brother has changed his mind...

"You have been misled by the professors of Jiang University, junior!"

"Ha ha!"

While bickering, the two had already walked into the building.

The research center is still lively.

Many people think that university teachers are very relaxed, such as winter and summer vacations, this perception is right or wrong.

For some lecturers who devote themselves to teaching posts, they can indeed enjoy vacations during the winter and summer vacations.

But for those professors who have aspirations, whether they have a vacation depends on whether they have a project in hand.

National, provincial, superior or enterprise cooperation...

Especially in the fields of biology, chemistry, environment, and materials, it is hard to say whether you can have weekends, let alone winter and summer vacations when you are rushing to catch up with projects.

Specific to mathematics, it is no longer an era when a pen and a piece of paper can solve problems.

Even if you want to use supercomputing in winter and summer vacations, you have to queue up, and the free computing resources of supercomputing are still limited, so you can buy them with project funds.

There are also hard-working graduate students and doctoral students who are about to graduate, but the results are not available, and the thesis is not enough...

Winter and summer vacation?

Hehe, you can live in a dream.

The world of adults - Ning Wei thinks it's actually not that difficult.

Because when he greeted the familiar professors and followed Lu Dongyi into Tian Yanzhen's office, before he could get ready to say hello to his future mentor, the boss threw a stack of materials give him.

"This is about the materials you applied for this year's top-notch young talents. Check to see if there are any problems. Especially the SCI, SSCI, SCSSCI collections and other citations listed in the application form. If it is incomplete, please make up for it. Oh, by the way, there is also your invitation letter to the SODA conference, Jiang University does not have the original copy, so if you have it, I will also make it up."

Ning Wei was a little taken aback...

what's going on?

Are all the bosses so social?

Without his knowledge, so many materials were prepared for him.

Such a terrible meeting ceremony, do you want to bald him too?

Seeing Ning Wei's bewildered expression, Tian Yanzhen smiled.

"Your Jiang University professors are pissing me off because of this! All these materials are confirmed to be all right, so give them to me. You will definitely be able to pass this application, and the subject is also prepared for you. About advancing the research on the NS equation , are you okay?"

------------

141 I dare not guide you anymore!

Ning Wei felt a headache.

In his imagination, it shouldn't be like this when he and Tian Yanzhen met for the first time.

On the day of his graduation thesis defense, Ning Wei inevitably listened to Professor Jiang Da's suggestions for his future.

For example, the choice of future research directions.

Ning Wei is not very interested in continuing to study the smooth and unique solutions of the ns equation.

Although the proposition given by Tian Yanzhen actually leaves room for it, he is only allowed to advance rather than completely solve this worldwide problem.But Ning Wei feels that the most valuable part of this worldwide puzzle has been completed.

Because he has found a way to deal with the solution when the research encounters the critical value problem, such as the Ningwei space that makes Lucasson Friend's heart, and the future Dangning's paper will be accepted by the world After the mathematician is sure, the conversion formula will probably be named Ningwei function.

The following research is actually very tedious and laborious.

The ns equation is an equation describing fluid dynamics, which has to consider various possibilities in number theory.

Therefore, to prove that the incompressible ns equation has a smooth and unique solution under any circumstances, it is necessary to specify and construct all possible extreme environments in mathematics, and then to prove that the physical quantity can be accurately located through this equation, which is very tiring and meaningless big.

To put it bluntly, it is similar to his EDA project, the framework is set up, and then to add details, isn't he out of his mind?

So when Professor Jiang Da told him that he should be extremely cautious in choosing topics in the future and could not listen to the advice of his tutor, Ning Wei had already thought carefully about his next research direction.

At this time, Ning Wei looked at his future mentor sincerely, and said sincerely: "Director Tian, ​​can you change the subject? Actually, I am very interested in statistics and big data recently. And at that time I As I told you, I am not very interested in continuing to study number theory, but I still hope to make some achievements in applied mathematics."

This sentence made Tian Yanzhen stunned.

Can't it be twisted?

I have made a major breakthrough in the research direction of the ns equation before, and continue to promote the research of the ns equation. Even if it takes three or four years to completely solve this worldwide problem, it is impossible to say that the youngest Fields Medal winner in history will be in China. Appeared.

The 26-year-old Fields Medal winner.

The youngest Fields Medal winner in history is the French mathematician Jean-Pierre Serre, who was 28 years old when he won the award.

This made Tian Yan really annoyed, but he didn't attack immediately, but asked: "Ning Wei, do you know why you didn't receive the invitation letter for the ICM Fort conference that just ended?"

"Huh? This year's icm conference is over already?" Ning Wei was stunned and asked back.

Tian Yan was speechless.

"So it's not that you didn't sign up because the organizing committee didn't invite you because you were young, but that the professors at the School of Mathematics at Jiangnan University didn't mention this to you?" Tian Yanzhen asked in surprise.

Ning Wei remained silent.

Indeed no one mentioned it.

This is actually a two-way misunderstanding. From the perspective of the professors at Jiang University, Ning Wei has already hooked up with Lao Tian. Even the second paper on the general solution of ns equations has written Lu Dongyi's name. Would Ning Wei come to such an important meeting? To participate, Yanda had already talked with Ning Wei.

If Ning Wei wanted to participate, he would have signed up long ago without receiving a special invitation letter.

From the perspective of Tian Yanzhen and Lu Dongyi, Ning Wei is still at Jiang University after all. If Ning Wei is interested in participating in this conference, the professors of the School of Science and Technology must have encouraged Ning Wei to go to the official website of the conference to fill out the application form to sign up. up.

Neither side thought that Ning Wei didn't care about the time of this year's International Mathematicians Conference at all, so when he went home to accompany his family, the conference had already finished.

Otherwise, Ning Wei is really interested in listening to it.

Of course, the reason neither side discussed this matter with him is that it is definitely impossible for Ning Wei to win the Fields Medal this year.

Seeing Ning Wei's innocent appearance, Tian Yanzhen's tone slowed down: "Well, it doesn't matter if you didn't attend. Anyway, it doesn't matter whether you go to this conference or not."

"But in fact, many mathematicians at this meeting asked about you and expressed regret that you were not able to participate in this meeting. The main reasons for the organizing committee not sending you an invitation letter are two reasons. First, you are solving ns The correctness of the Ning’s space solution method given on the equation problem needs to be further verified by the mathematical community. Second, two papers that solve key problems, including the one you collaborated with Lu Dongyi and the one that proved the kls conjecture, were published It's too late."

"But it doesn't matter, you are still young, you are only 22 years old this year, and you will only be 26 years old at the icm conference four years later, which means that the next icm conference will really be your performance stage. But this involves a problem, you are currently in The most important achievement in mathematics is a supercritical value research solution to be verified, and the proof of the kls conjecture. It is not known whether this will allow you to get the Fields Medal in four years."

"After Lucasson Friend's incident, you should also understand that the mainstream judges of this kind of academic awards are still those scholars in the West. This also means that you need to be more convincing if you want to conquer them four years later. The results are proof!"

"If you can continue to advance in this direction, and even fully prove this difficult problem, plus the achievement of proving the kls conjecture, I can say that you will be the most shining new star in mathematics at the icm conference four years later! They can't find you refuse to award you the Fields Medal for any reason."

"However, if you change your research direction now, it is still unclear whether you can produce world-class results in four years. But even if your solution is proved to be correct, more mathematicians will use your method to advance ns equation, and in the nomination and selection process of Fieldsell, you will definitely get a very high voice, but it is not foolproof, do you understand?"

Tian Yanzhen sincerely tried to make Ningwei change his mind.

Of course, this is not just his expectation. In fact, many mathematicians in China now hope that Ning Wei can win the Fields Medal in four years.Think about it, at the same time as achieving the breakthrough of 0, it also directly broke the breakthrough of the minimum age of Fields winners. This is something worthy of special mention.

In short, Ning Wei's talent cannot be wasted by him!

However, Ning Wei still shook his head and said: "Director Tian, ​​I know you are doing it for my own good. Actually, I have thought about this problem for a long time, but I am not really interested in continuing to advance the ns equation. I have also studied the Philippine To put it bluntly, the reason for awarding the Ertz Prize is either to solve a worldwide problem, or to establish a school. I want to take the second path now. To tell you the truth, I really have a little experience in statistics now. "

Having reached this point, Ning Wei still insisted on his own opinion, which made Tian Yanzhen feel that he had nothing to say.

Especially with a little experience in statistics, there are so many people with a little experience in statistics, why haven't I seen anyone take Fields?

As for Lu Dongyi next to him, he was completely overwhelmed by the calmness shown by the younger brother.

Everyone pushes you to get a Fields back, but you want to change the research proposition at a critical moment?

Could it be that the sudden inspiration during the Chinese New Year was fake?

"Okay, then tell me, what proposition do you want to study next?" Tian Yanzhen asked, suppressing the anger brewing in his chest.

"The new big data calculation and the basic algorithm mathematical construction of strong artificial intelligence." Ning Wei blurted out without hesitation.
