From a university student to a chief academician

Chapter 120 Information Security Crisis
Kyoto, Xia Guo Security Department, conference room!

Everyone's expressions were serious, and there was tension in the air.

Sitting in the first seat is the Secretary of the Security Department, Zhang Sui Zuyun.

Sui Zuyun said: "Everyone, the international situation is becoming more and more tense now. As one of the powerful countries, if we want to develop, information security is very important."

"Most of our country's software and hardware are imported, which is very dangerous to information security."

"Network monitoring, remote control, data theft and other things happen all the time."

"This is still a visible loss, and there are more invisible losses."

"So, everyone, the information security situation is at stake!"

"Let's talk about how to solve the current information security situation."

Everyone looked at each other and discussed with each other.

Sui Zuyun looked at the crowd, his heart was also battered.

Information security has always been a headache for all countries, and information security has always been managed by the Security Department.

As the country with the largest number of netizens, Xia Country also has the largest information security crisis in the world.

After a long time, Mai Yuan from the Department of Education said: "Most of the methods for eavesdropping on information now come from the Internet, so we should strengthen the development of cryptography."

"As we all know, encryption facilities are the immune system of cyberspace security. Passwords are not only immune genes, but also integrated into all aspects of the information system to form a password protection system. It is an important part of the network security protection system and plays a foundation and support role."

"Strengthen the password modernization program and change the passive defense strategy of endless patching and blocking."

"This can solve the information security crisis to the greatest possible extent."

When everyone heard this, they all nodded secretly.

To defend against network security, it is most feasible to strengthen the development of cryptography.

Sui Zuyun said: "But cryptography does not develop just because it is developed. Since 1959, my country has been studying cryptography for 66 years. However, compared with some countries in the world, there is still a big gap."

Cryptography is no stranger to Xia Guo, it appeared thousands of years ago.

In ancient times, it was a text or digital password, and in modern times it is a network password.

The word password is not a simple account number and password.

It is a technology, product and service that adopts a specific transformation method to encrypt and protect information and securely authenticate it.

In 1959, under the instruction of Qian Xuesen, Changan University of Electronic Science and Technology took the lead in conducting cryptography research.

In 1988, the country's first master's program in cryptography was established.

In 1993, the country's first Ph.D. program in cryptography was established.

Until now, Changan University of Electronic Science and Technology's cryptography major ranks first in Xiaguo.

Mai Yuan said: "Of course I know this, but the situation is different now."

"President Sui, cryptography mainly relies on mathematics. Our country is now full of talents, and its scientific development is catching up with a technologically powerful country. It has become a technologically powerful country, and the development of mathematics is obvious to all."

"Mathematics mainly relies on geniuses, and our country has a large population, so there are many geniuses."

"For example, some time ago, there was a young mathematician at Zhonghu University who proved the ABC conjecture, and he was only 24 years old."

"Whether they are domestic or foreign, they are all top talents."

"And there are many geniuses like this in our country."

"Isn't this a proof that our country is full of talents?"

"Therefore, there is a lot to be done to strengthen the development of cryptography."

"We should gather mathematical talents from all over the country to study cryptography, so that we can improve our country's cryptography strength in a short time."

"The information security crisis can be quickly resolved."

Geng Ye from the Science and Technology Department said: "Is the person you said who proved the ABC conjecture Ye Fei from Zhonghu University?"

Mai Yuan was stunned for a moment, and asked, "Mr. Geng also knows about him?"

"Of course." Geng Ye said, "I recommended him to enter the Number Theory Association!"

"Not long after he entered the Number Theory Association, he proved the ABC conjecture, so I have a share of the credit for his ABC conjecture!"

"It's him." Mai Yuan said: "He is a genius, and my education department has been paying attention to him. I didn't expect Mr. Geng to also pay attention to him."

"Okay." Sui Zuyun waved his hand and said, "Stop talking about gossip here, and continue talking about information security!"

"What do you think about strengthening the development of cryptography?"

Everyone discussed with each other, and then someone said: "Mr. Geng, I think Mr. Mai's proposal is very good. He is engaged in education and knows the country's talent development best."

"So, he said that strengthening the development of cryptography is promising, so there must be great potential."

"Besides, in the past years, we have always blocked information security wherever there is danger."

"It's always after the danger first that we discovered it, and then blocked it."

"At this time, the danger has already occurred."

"Although losses can be reduced, losses still occur."

"A behavior like this is not advisable!"

"We should turn passive into active."

"To strengthen the development of cryptography is to take the initiative."

"Although the development of cryptography is strengthened, the benefits will not be seen in the short term."

"But in the long run, the advantages outweigh the disadvantages."

"So, we should strengthen the development of cryptography."

Everyone nodded, agreeing with what this person said.

Sui Zuyun said: "Do you have any other opinions?"

Some people proposed to develop computer hardware and build the country's own brand. All hardware should be 100% made in Xiaguo.

The idea was rejected as soon as it was proposed.

This is too difficult, and it is impossible to do it with the current Xia Guo technology.

Mainly high-performance graphics cards and low-nanometer chips, which Xia Guo could not manufacture.

Although Xia Guo can manufacture mid-performance graphics cards and high-nanometer chips.

But such computers run too slowly, and people rarely buy them.

Most people who buy a computer look at the performance first, and then the brand.

There are very few people who buy computers produced by the country because they are patriotic.

And in the end, I found that the computer I bought was running too slowly, and I would eventually replace it with a foreign-made computer.

Others talk about developing software to build Xiaguo's computer system.

Still rejected.

In fact, making a computer system is very simple, and many people can make it.

The reason why it has not been produced for so long is because almost all programmers in the world create software based on the two computer system environments of Microsoft or Mac.

The reason why there are only Microsoft and MAC in the computer system in the world is that it does not gather the power of one or two companies, but the power of everyone in the world.

Xia Guo wants to have his own computer system, unless all programmers around the world can create software based on this system.

Otherwise, the computer system produced is useless.

Others say to build a powerful firewall, intrusion detection system, security detection system, vulnerability scanning system...

But it is still considered otherwise, although these things are helpful to network security.

But compared with cryptography, there is a big gap.

Sui Zuyun said: "Okay, let's vote with a show of hands. If you agree to strengthen the development of cryptography, please raise your hand."

In an instant, more than [-]% of the people present raised their hands.

The main reason is that the opinions put forward by other people are not as good as the opinions on strengthening the development of cryptography.

Sui Zuyun said: "56 people, 45 people agree, more than half."

"Okay, pass, then strengthen the development of cryptography."

"Let's talk about how to develop cryptography."

Afterwards, everyone was chatting again.

The meeting was held for a week, during which many well-known domestic cryptography experts were consulted.

Finally, the research direction of cryptography was determined to be 14 technical priority research fields and 13 important investment fields.

For the study of cryptography, there are three main directions.

They are encryption algorithm innovation, encryption mechanism innovation and certificate structure innovation.

A cryptographic algorithm is a set of operational rules or procedures for cryptographic processing.

Cryptographic mechanism, also called cryptographic system.

The certificate structure is the certification that the cryptographic algorithm can run, which is equivalent to a certificate and a license.

The cryptographic algorithm plus the certificate structure operates on the cryptographic mechanism.

For example, the encryption mechanism is a small town, the encryption algorithm is a store, and the certificate structure is the business license for opening the store.

The cryptographic algorithm plus the certificate structure is placed on the cryptographic mechanism, and the cryptographic algorithm can be run.

Finally, when the meeting was about to be dissolved, Sui Zuyun said: "A cryptography meeting will be held."

"That Ye Fei from Zhonghu University, since he is a math genius, invite me."

"Other math geniuses across the country should also invite me."

"For this conference, we will gather all the geniuses and experts in mathematics and cryptography from across the country."

"We need to gather the strength of the whole country to solve the information security crisis to the greatest extent."

"Okay, Mr. Sui!" A man said, he was the person who specially presided over the invitation list.

"The most important thing is that the identities of all participants in the meeting must be carefully reviewed, and some people with bad ideas must not be allowed to participate."

"Yes, Mr. Sui!"

…………

Zhonghu University!

After returning to school, Ye Fei continued to devote himself to research.

Another half month later, the time came to the beginning of November.

Half of the research on elliptic curves has been completed, and there is a maximum of one month to complete the next half.

Ye Fei's office!
Everyone sat on the stool, and Ye Fei also sat on the stool, saying: "Everyone, based on the research between the elliptic curve and Diophantus, we can study it from the ring k."

The full name of the research on the ring k on Diophantus is called the algebraic integer ring solution on Diophantus.

In general, the Diophantine problem is unsolvable, the tenth of Hilbert's 23 problems.

Of course, their research only borrowed part of the knowledge in the Diophantine equation and integrated it into the elliptic curve.

Ye Feidao: "The subset K of the algebraic integral ring K of the countable number field K..."

He talked for a full hour.

At this time, he saw the dean appearing at the door of the office.

Ye Fei said: "Everyone digest what I just said first."

After speaking, he stood up and walked out.

"Dean, why are you here?" Ye Fei smiled.

The dean smiled and said, "The number theory team did a good job for you!"

Ye Fei laughed and said, "It's okay, it's okay."

"I know that you treat your team members very well, and take them out to make money. In just over a month, you have led each of your team members to earn more than 100 million."

"I let you enter the number theory group, just to let you learn management skills, so that you can enter the school's management."

"But I didn't expect you to find another way to take your team members to make money."

"Everyone likes money, and your team members like money too."

"They see the benefits in your hands. I believe that you must be right in the number theory group."

"Many people still ask me to join your group."

"How is it? Do you want to add some people?"

"No!" Ye Feilian waved his hand and said, "Dean, the number of my team members is enough, and there is no need to increase it. The current number is just right for me, and it will be a burden for me to increase."

"If I take them out to do projects, the team members with more people will get less money."

"It's time for them to have an opinion."

"But now these people, I just do enough projects, and everyone gets a lot of money."

"Okay!" said the dean, "Then I will reject them."

"Dean, you came to me to talk about this?"

"Of course not, how is your Gauss conjecture research?"

"It's okay, the research is at the end of the second question, and it's almost finished."

"So fast?" The dean was astonished.

Then he said in amazement: "Ye Fei, your research speed, why does it feel like the results of the research are in front of your eyes?"

Ye Fei smiled and said, "I hope too, but unfortunately not."

The dean shook his head and said, "I have something to tell you."

"Say it!" Ye Fei said.

"How much research do you have on cryptography?"

Ye Fei said: "It's okay!"

The dean said seriously: "You can't give ambiguous answers, you have to give specific numbers."

Seeing the dean's serious expression, Ye Fei tentatively asked, "Is this very important?"

"It's very important." The dean said: "So you must answer seriously."

"Okay!" Ye Fei thought for a while and said: "AES encryption and decryption, CA authentication system, elliptic curve cryptography mechanism, discrete logarithm, verifiable key agreement, elliptic curve zero-knowledge authentication, PostgreSQL password authentication...these are all It's my research."

He says more than 50 cryptographic studies.

These are the contents of Ye Fei's research for so many years.

Cryptography is all about the study of mathematics, which uses a lot of knowledge of number theory and algebra, especially number theory, which is the most used knowledge of cryptography.

Therefore, when he studied number theory, he also studied cryptography.

"Good!" The dean nodded.

After pondering for a while, he said, "Do you want to study cryptography?"

"Uh..." Ye Fei asked in surprise, "Cryptography?"

"Yes!"

"It's not that research is impossible, but I'm studying Gauss' conjecture, so let's just study cryptography!"

"If I study cryptography, it will greatly delay my research on Gauss' conjecture."

The dean looked around and whispered: "Well, there is a conference on cryptography, you go to attend it, as for whether to study cryptography in the future, let's talk about it later!"

"Very important?" Ye Fei asked a little bit embarrassed.

He is not very willing to participate. Gauss conjecture has been studied for a long time, more than a year, but the research has not been completed yet.

He wants to finish the research as soon as possible so that he can carry out the next research.

"You'll know when you go."

Ye Fei took a deep breath and said, "Okay!"

"When will you participate?"

"At the beginning of next month, the participants in this cryptography conference will gather talents from all universities and research institutes across the country, and the specifications are very high."

Ye Fei asked suspiciously: "Dean, what are you going to do with gathering so many talents?"

If something goes wrong, there must be a demon. Such a high-level meeting will never be a simple meeting.

"How do I know." The dean shook his head and said, "Anyway, it must be a big event, and it must be beneficial to participate, so I let you go."

The dean didn't know the specific information, he just received instructions from above to ask Ye Fei to attend the cryptography conference.

"Okay!" Ye Fei said, "Where is the address?"

"Kyoto, I will send you the specific address later."

"Row!"

After talking with the dean, Ye Fei entered the office and continued to study.

Not long after the dean left, Ye Fei received the address from the dean.

One month later!
Ye Fei wrote on the whiteboard.

[Fixed number field K, let L be the Galois closure of K/Q, for each g∈Gal(L/Q), let L represent the fixed field of g in L, then L/L...]

[Finally, the proposition is established by Matiyasevic's theorem. 】

[Then the elliptic curve proof is complete! 】

Ye Fei put down the ink pen in his hand, turned to face the crowd and said, "Everyone, this is the whole proof process of the elliptic curve."

"We've hit another milestone."

"Oh..." Everyone cheered, with excited expressions on their faces.

Every time they complete an academic study, they are full of a sense of accomplishment.

Although most of the credit for this academic research belongs to Ye Fei, they are also honored as his collaborators.

Ye Fei was also very excited. He gathered the strength of everyone, absorbed everyone's inspiration, and researched it together.

If there were no people present, he would not have researched each academic problem so quickly.

Amata and the two were also very excited. It was right to come to Xia Kingdom, and it was very easy to study with Ye Fei.

Ye Fei said: "Everyone, this research is over, let's take a break."

"Ah..." Someone complained: "Leader, why are you resting again, keep up the good work!"

"Team leader, are you going to take us to some projects?"

When everyone heard this, they all looked at Ye Fei with bright eyes.

Ye Fei shook his head and said, "No, I'm going to attend a meeting. I don't know when it will end."

"Hey..." Everyone sighed regretfully.

Ye Fei smiled and said: "Don't be discouraged, everyone. If you really want to do a project, I have a lot of projects in hand. After the research on the Gaussian number conjecture in the imaginary quadratic field is finished, I will take you to do one."

Ye Fei also has a certain network now, if he wants a project, he can get it at any time.

There are projects as small as 10,000+ and as large as several million.

So, don't say that university teachers are poor.

Those who are poor are all incompetent university teachers, and those who are capable are very rich.

"Oh..." Everyone cheered: "Long live the team leader."

Ye Fei smiled and said, "Okay, let's leave!"

It was three o'clock in the afternoon, and it was not time to get off work. Ye Fei went back to the office of Tan Lingling and the others to sit down and rest, and happened to chat with Tan Lingling and the others.

In a blink of an eye, another three days passed, and tomorrow is the time for the cryptography conference.
