The end of technology.

The flag-raising ceremony in the capital has been admired for a long time, and of course I have to participate.After watching the flag-raising ceremony, I just went to pay homage to the remains of the great man, and then took a photo on the ancient city wall; when I came to the capital, I had to go to the Forbidden City to have a face-to-face with the Forbidden City to see the once royal family's home; once the royal garden had to turn around; I have to choose one night to go to the legendary National Grand Theater to watch a drama performance.In the end, Ning Xiao also planned to climb the Great Wall to earn her title of Hero of the Women's High School.

A week is just right.

What makes Ning Xiao even more happy is that President Chen also took the initiative to say that she can live in the hostel of the University for free until Yanbei University arranges accommodation.The internal environment of the hostel is actually very good. If you want to find a hotel with a similar location and environment outside, the price will be several hundred.The principal's words were equivalent to saving her a four-digit accommodation fee and making this trip much more convenient.

So downstairs in the administration of the University, the siblings firmly declined Principal Chen's proposal to send a few people on a trip, and after saying goodbye to Academician Fan and Chen Yonggang, Ning Xiao couldn't help but sigh: "No wonder smart people are busy cursing. As for the leader, just a word from the leader can save me the equivalent of half a month's salary."

Dad Ning smiled honestly, without saying a word, just raised his hand and patted Ning Ruo's shoulder.

The father and son are actually not very good at expressing, and many times all the feelings are placed in these daily actions.

It turned out that Ning Xiao was more careless than the father and son, so he directly hugged Ning Zi's shoulders, and said affectionately: "Brother, your dear sister, I have been honored by you this time, and I plan to be with you this week Going around the capital, if you have anything you want, just mention it, and my sister will give it to you. You know, when I left this time, my stingy mother took the initiative to transfer 2 yuan to me for the first time."

Before Ning Yu could answer, Dad Ning couldn't bear it any longer, and taught him a lesson: "Ning Xiao, how can you arrange your mother like this? It makes your mother not sad to hear it? And it's not easy for them to make money. , I gave you money so you can live a good life in the capital, so you can save some money. Big cities are no better than small places like ours, and you will need more money in the future!"

Ning Xiao pouted and said nonchalantly, "Uncle, it's boring if you say that. I'm not looking at my brother's great prospects. With Ning alone here, I'm afraid that no one will care in the capital in the future? Even if I didn't dare to spend money indiscriminately before, now I have the confidence. Who gave me a super powerful brother!"

This is right, and the gully polished by life on Dad Ning's face instantly bloomed into a rough flower: "That's right, that's right, hey, this kid Ning Ruo is good in everything, just like me, Can't talk. If he can talk like you, I'm really relieved."

Ning Xiao curled his lips and said, "Uncle, what you said is wrong. Do people who are capable still need to be able to speak? Those who want to deal with our little family in the future must think carefully about how to speak. Yes. Come on, Ning Yu."

Ning Ru quietly listened to the conversation between Dad Ning and his cousin. He actually liked this kind of life-like conversation.In particular, he really admired his cousin's ability to make Dad happy every time with just a few words.Really, he hadn't seen his father smile so happily in a long time.

It's just that when I heard my cousin turn the topic to him, I suddenly got stuck again...

He didn't know how to answer this.

Ning Xiao knew Ning Ruo's temperament, so he didn't really intend to let him answer, but said seriously: "Ning Ruo, you have to have some confidence. You didn't pay attention when you were eating, but I saw it all. Principal Chen looks at you with light in his eyes. You must not belittle yourself in the future. Anyway, my sister is very sure that your future achievements will definitely be higher than everyone who eats together today. In the future, others will beg you, It's not you who begged others."

Ning Yu nodded heavily, of course he knew what Ning Xiao said, but it still felt very strange.

Suddenly, he was the backbone of the family.A man's sense of responsibility, at this moment, made Ning Ruo fearless about everything he was going to face next, even if it was just for his family.

Not to mention that you have to study hard when you are sleeping and when you are awake?

……

When Ning Zhi continued to study hard in her dreams, many people had to stay awake and work overtime.

Generally speaking, the verification of a new technology will be a very tedious thing.After all, new technologies represent a new set of standards.

But this time things are different.

The manual in both Chinese and English versions is so detailed that it is outrageous, and it is like guiding a group of technicians as elementary school students.

As long as the test environment is arranged and the program is installed according to the instructions, the most troublesome thing is probably to arrange the algorithm. However, the parameter settings for different environments in the manual are also extremely detailed, taking into account almost all situations, just follow the documentation to set Just OK.

The next step is simple.

After it is arranged on the server, it is only necessary to perform DDOS attacks on it, and then use various malicious web crawler programs to crawl information, and use various devices to record the status of the server, and finally automatically generate a perfect report.

For the few people who stayed up late at Youwei's headquarters, all the overtime work went extremely smoothly this time.Of course, if it doesn't go well with the documentation, the testers from these technical departments and the department heads who recruited them into the company can line up to go to the hospital to test their IQ.

When Ning Yu finally finished the question in his dream and opened his eyes to meet the first rays of sunshine in the capital, the companies behind the huge Internet had already begun to fry.

Chapter 071 Principles are most afraid of giving too much

"Robert, the turbulence algorithm published on the forum in March, we did a series of tests today, and now it has a 300% success rate in defending against DDOS attacks with a strength greater than 0G, and an error rate of [-]! I don't know how this algorithm does it. Yes, but it really distinguishes malicious attacks from normal access from the myriad of connections and shows you what that means!"

"Of course, of course, well, Armand, of course I understand what that means. Don't get excited. What I need to know now is that this... um, is called Turbulence Algorithm, right? Who owns the patent for this technology? hands. You know, it's important."

"This is the problem, Robert, you may not believe me, I just asked the company's legal department to inquire about the patent status of this algorithm technology on a global scale, and the answer so far is that this technology is available in major countries around the world. Has not applied for any patents. No patent application, not a single one! Although a collection account number and detailed charging standards are left on the instruction manual, the other party has not applied for a patent!"

"What did you say? The developer didn't apply for a patent?"

"Yeah, you heard right Robert, you know? I didn't believe it at first, but I checked it out myself and didn't miss any possible keyword to search! No, none! Now we're sure about this set Everything about the turbulence algorithm has not applied for any patents, only one relevant copyright registration information has been found. However, the author directly published the source code on the forum, and only included a charging standard in the description document!"

When Aardman Diess reiterated this conclusion in a very excited tone, Robert Finney was stunned for a while, and then a bright light burst out in his eyes.As a Cisco marketing executive, he certainly understands what it means to not file a patent.

This is a trillion-scale blank market, and it is an irresistible temptation for any Internet security solution provider and network equipment manufacturer in the world.

In the eyes of the two, this is obviously a huge mistake made by the algorithm author.

Or perhaps the venerable author didn't realize the commercial value of turbulence algorithms at all.

Think about it, when the algorithm is popularized on various network data exchange devices, it means that hundreds of millions of meat machines used for DDOS attacks will lose their original functions. This is absolutely huge for Wall Street companies. good news.

You must know that every year those big companies on Wall Street spend a lot of money to defend against various cyber attacks.

Now that they have this technology, they can't wait to iterate on all the devices.Of course, it's not just Wall Street, all financial service providers in the world, all game service providers, cloud service providers, etc., will be crazy about it.

Of course, the people who were about to go crazy also included the two people who were facing each other at this time.

Robert Finney couldn't even hold back his saliva.

"I didn't apply for a patent, but just gave a charging standard in the specification? And it can be used directly?"

"Yes, Robert, it's still a very detailed multi-version, and even includes a hardware version that can be directly written to the chip. There is only one problem. The documentation emphasizes that if you want to use it commercially, you must first buy an activation code. Otherwise, the consequences will be at your own risk. Each activation code of the hardware version corresponds to a unique device, and each activation code of the software version corresponds to a server device.”

"What's the difference between the two?"

"This is what we don't quite understand. The original version and the paid version after activation have been tested separately, but in all laboratory environments, the effects of both are basically the same for DDOS attacks and malicious crawlers. There are no significant differences. Testing is continuing and our senior engineers are analyzing the original source code."

"It's all the same? Aardman, Mr. Douglas certainly doesn't want to hear such an answer. I'm sure there must be a difference. Well, I don't know the technical stuff, but maybe it'll allow our scientists to activate the Compare the source code before and after to find the differences?"

"Of course, Robert, we actually tried to do that. The problem is that the activation code probably corresponds to an encryption algorithm. The public version is indeed open code, but after using the activation code, the original open source code is directly encrypted. Our scientists are trying to crack encryption algorithms, and the bad news is that it’s really cumbersome, and even using supercomputing at all costs may take a long time or never to crack.”

"Okay, so have you contacted the original author?"

"Only one email address is left on the forum. We have already gone to the email, but have not received a reply. This email belongs to Huaxia's Yiwang Company. When we checked the author's identity, we made some interesting discoveries. Recently, a paper was published in Princeton's Annals of Mathematics. The email address left by the paper is the same as this email address, and the author's name is Ningjie."

"Mathematics paper?"

"Yes, the problem solved is also very interesting. A paper on the conjecture of the hyperdimensional cube, which happens to be a problem in the direction of computer optimization. Now the mainstream view in the mathematics community is that the author has solved this conjecture perfectly. I have also I found someone to contact the editor-in-chief of the Annals of Mathematics, but the other party refused to provide the author's phone number. By the way, there is another interesting thing, you must not have thought of it. "

"what?"

"The author of the paper and the algorithm, Ningjie, is a student of a sports university in Huaxia. Let me think about it, yes, it's called Yanbei Sports University."

"Yanbei Sports University? A branch of Yanbei University?"

"No, no, it's Yanbei Sports University, which has nothing to do with Yanbei University. But I found news on the Internet that Yanbei University supported the university to build a mathematics department not long ago. It is said that this Ningjie is the only mathematics department in this department. students, but haven't officially entered the university. God, the idea of ​​​​the Chinese people is so weird."

"It's really too confusing! Chinese people just like to complicate things that should be simple. But I don't care about these. So now we get the information that the author of the algorithm is a Huaxia student who has not officially entered the university. He A math genius or a computer genius who published a math paper that solved a computer problem, and has no other information."

"From this identity, we can probably judge that he may not know the specific business profit model and patent profit model, or even know nothing at all. He doesn't even know that the algorithm he designed should apply for a patent before it can sell for a good price, right? ?"

"I guess that's about it, Robert. But that doesn't explain why he would require the code to be activated for commercial use. An activation code generator and corresponding encryption algorithm were also designed for this purpose."

"No no no, Armand, don't you understand yet? Forget about the damn activation code, now the most important thing is to find a way to find that guy named Ningjie! Then call the editor-in-chief to get to the author's phone number, and then tell our colleagues in Huaxia, let them visit immediately, if you can pull people into Cisco, you know what that means? Right! Of course you should know!"

"But the editor-in-chief refused to..."

"You can give money! Give a lot of money... God, do you want me to teach you this? Armand, everything in this world has a price. If he refuses to speak, it must be that the price is not high enough. Go and tell That damn editor-in-chief, how much does he want! As long as it's within $[-], promise him immediately, don't hesitate for a second, understand?!"

"..."

……

Similar conversations are taking place in many parts of the world at the same time.

Although it is only a preliminary test for the algorithm, the name of the moderator in March, combined with the results of the preliminary test, has made countless people realize how much this new algorithm is about to have an impact on the entire Internet world.

Simply put, the emergence of the turbulence algorithm is equivalent to a patch, a special patch for the security of the current Internet and the future of the Internet of Things.

Since the birth of the Internet, the TCP/IP network protocol that constitutes the most basic Internet has natural defects, which directly leads to the fact that DDOS attacks based on large traffic are almost insoluble for the entire Internet security. For practitioners, they can only carry out passive defense.

This is also the reason why the Internet has been born for nearly a century, the most primitive hacking methods are still popular, and the specific technical means are still constantly being introduced.

The technical principle is very simple, everyone who is involved in security knows it, but it is impossible to prevent it.Unless the entire Internet infrastructure is changed.

As described in March, the emergence of the turbulent algorithm means that the Internet black production that has been basically impossible to eradicate will soon disappear in the near future.This is indeed a great blow to countless hackers.

What is even more amazing is the ability of the turbulent algorithm to intelligently distinguish malicious crawlers.

Once popularized, it will be of great help to protect intellectual property rights and protect the legitimate rights and interests of countless ordinary people.

For example, for Huaxia, 12306 no longer needs those anti-human verification codes during the Spring Festival every year, which is enough to ensure that it is impossible for those scalpers to pass the software and grab popular tickets in an instant.

Similarly, the airline's official website occasionally launches extremely low discount air tickets to attract customers, and it will no longer be a profit-making tool for scalpers. At least technically, the scalpers who once dominated China will no longer be able to use the software to keep track of them. Lock down these ticketing resources.

Not to mention that the author also directly gave two solution modes of turbulence algorithm, hard and software.

This means that in the next few years, countless servers around the world will deploy this algorithm, and almost all network equipment in use now, including various types of routers, switches, hubs, gateways, etc., will be upgraded in the not too distant future. A device with a turbulent algorithm chip, thus completely eliminating the brute force attacks that have plagued the Internet for decades.

What's more, almost all big customers will be willing to pay.After all, the financial networks, game service networks, and government affairs networks that have been attacked the most are basically the ones who are not short of money, and the annual losses caused by DDOS attacks to these industries are astronomical, and these industries have to spend Large sums of money are used to prevent DDOS attacks.

So in just one day, almost all large and small companies related to Internet security and network equipment have set their sights on [email protected], the owner of the free mailbox.

All enterprises with a certain scale have already found the name of Ning Zhi through various channels, and began to pay attention to Yanbei Sports University.

However, what made everyone scratch their heads was that no one could be sure where Ning Yu was now.

It's very simple, because according to the information these people have inquired about, Ning Ru is a student of the mathematics department jointly established by Yanbei Sports University and Yanbei University, but the mathematics department has just been established. In other words, the official class will have to wait until September next year. After that.So theoretically, Ning Zhi should not have entered the school yet, so he should stay at home.

But Huaxia is so big, even for many domestic companies with supernatural powers, it is not a particularly simple matter to determine where the other party's home is at the first time through a name and other information that is not too much.After all, it is a big country with 960 million square kilometers and a population of 14 billion.

So the "Annual of Mathematics" was lively.

……

Robert Kenny is 52 years old this year, and he has lived most of his life. After all, the average life expectancy in the beautiful country is only 77.6 years old.

He had never experienced something like this today.

A group of people are waving cheques for the phone number and communication details that an author left in a submitted paper.

Sure enough, as long as you live long enough, you can always see enough rare things.

In fact, Robert Kenny does not feel that he is very short of money.

As the editor-in-chief of the "Annual Journal of Mathematics", the annual salary of nearly 20 US dollars plus the benefits provided by the organizers of various activities and some other income are enough for him to live a relatively good life in Princeton.

So Robert Kenny felt he could stick to his principles.

But unfortunately the other party gave too much...

Do you believe he can get a check for $3 and a lot of extra promises as long as he gives Ning Ruo's private number?More importantly, this was not a price offered by a company. Even when he hesitated, the professor who represented Google directly increased the price to $5!

To be the editor-in-chief of "Annual Mathematics", the basic mathematical calculation ability is still very strong.You won't even be able to calculate change in the supermarket like ordinary people.

So after a few phone calls, he quickly calculated that if he lowered his principles a little bit, he would be able to get his salary directly equivalent to a year and a half, and there was a promise that the money It will be credited to his account in some legal and tax-free way.For example, he can apply for a personal laboratory, and these donations will directly become the start-up capital of the laboratory.

In other words, as long as the same operation is replicated, Ning Ru's phone number and contact information will bring him about $30 in after-tax legal income.

This is obviously a large sum, and he can switch to a luxury car, give the family a luxurious vacation trip, and have more protection than his pension account.

The only problem is that these commitments are time-sensitive and don't give him much time to think.

Since these people are willing to pay such a high price to get Ning Yu's contact details from him, they will naturally find others.Other editors of the journal, or those professors in Huaxia, maybe those people can't stick to the principles?

So, after hesitating for about 2 minutes, the editor-in-chief of the "Annual of Mathematics" finally decided to temporarily abandon some principles he had always insisted on.

Of course, principles are the hardest when you let them go for the first time. When you pass the test in your heart, go to the second and third time when you touch principles...it's much easier.

So in just 5 minutes, he made nine phone calls, re-determined the conditions, harvested the promise, and then gave the information.

After hanging up the phone and doing a simple calculation, Robert Keney concluded that the total value of the nine calls was a full $32.

"This is the only time!" Looking at the number he wrote on the paper, Robert Kenny comforted himself in his heart.

But the next moment, the mood will be cheerful. After all, if you give up the principle a little, you can get so much income. This does not seem to be an unbearable thing.

What's more, Robert Kenny believed that those calls that urgently needed Ning Yu were all well-intentioned.

Is it a cross-generational algorithm that drives countless multinational high-tech companies crazy?

That Chinese boy is really lucky.

Wait, if he, like other editors, threw this kid's paper directly into the trash after only looking at the name and unit...

Thinking of this, Robert Kenny finally let go of all his psychological burdens.

After all, he is considered Ning Wei's Bole, and revealing some information in exchange for some benefits does not mean that he has given up the principle, right?

……

If Robert Kenney was targeted by a group of people, then the Yanbei Sports University is even more lively.

It happened to be the admissions season at the end of June, and the phone calls of the admissions office were usually very busy at this time. As a sports university in the first echelon of China, it is still very popular.For the old students, most of them are busy with the upcoming final exams.

Especially for students studying sports science, many specialized courses are also difficult.If you don’t work hard at ordinary times, you have to enter a tense review state at this time, otherwise, failing to retake the exam will hurt both your money and your face.

It's basically the same every year, but this year is especially different.Or this June 6rd is extraordinarily different.

The entire university, from leaders to professors, and even some students, have received a lot of calls during this busy season, asking if the school has recruited a student named Ning Ruo, and even further hopes to help find out this person named Ning Ruo. Students in some details.
