From university academician to chief academician

Kyoto, Xia Guo Security Department, conference room!

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

Sitting at the head of the table was Secretary Zhang Suizuyun of the Security Department.

Sui Zuyun said: "Everyone, the international situation is becoming more and more tense now. As one of the powerful countries, if our country wants 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, but the invisible loss is even greater."

"So, everyone, the information security situation is very critical!"

"Tell me how you can solve the current information security situation."

Everyone looked at each other and started discussing with each other.

Sui Zuyun looked at everyone, and his heart was very anxious.

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

As the country with the largest number of Internet users, Xia State 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 information now come from the Internet, so we should strengthen the development of cryptography."

"As we all know, cryptographic facilities are the immune system for cyberspace security. Passwords are immune genes and are integrated into all aspects of the information system to form a cryptographic security system. It is an important part of the network security security system and plays a foundation and supporting role."

“Strengthen password modernization initiatives and transform passive defense strategies of endless patching and blocking.”

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

When everyone heard this, they all nodded secretly.

If you want to defend network security, it is most feasible to strengthen the development of cryptography.

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

Cryptozoology is no stranger to the Xia Kingdom, having appeared thousands of years ago.

In ancient times, it was text or numerical passwords, and in modern times, it is network passwords.

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

Instead, they use specific transformation methods to encrypt, protect, and authenticate information, products, and services.

In 1959, under the instruction of Qian Xuesen, Chang'an University of Electronic Science and Technology took the lead in carrying out cryptography research.

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

In 1993, the country’s first doctoral program in cryptography was established.

Until now, the cryptography major of Chang'an University of Electronic Science and Technology ranks first in Xia State.

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

"Mr. Sui, cryptography mainly relies on mathematics. Our country is now full of talents. Its scientific development is catching up with the technological powers. It has become a technological power. The development of mathematics is also obvious to all."

"Mathematics mainly relies on genius. Our country has a large population and there are many geniuses."

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

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

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

"Isn't this proof that our country is rich in talents?"

"So there is a lot of potential to enhance the development of cryptography."

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

"Only can information security crises be solved quickly."

Geng Ye from the Department of Science and Technology said: "The person you mentioned who proved the ABC conjecture is 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: "He can enter the Number Theory Association because I recommended him!"

"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. Our Education Department has been paying attention to him. Unexpectedly, Mr. Geng is also paying attention to him."

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

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

Everyone was discussing among themselves, 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, if he said there is much potential for strengthening the development of cryptography, then there must be great potential."

"Furthermore, regarding information security in previous years, we have always blocked wherever there is danger."

"We only discovered it when there was danger first, and then we blocked it."

"The danger has already occurred at this time."

"Although it can reduce losses, there are still losses."

"Such an act of trying to fix the problem before it is too late is not advisable!"

"We should turn from reactive to proactive."

“Strengthening the development of cryptography is taking the initiative.”

"Although the development of cryptography is strengthened, no benefits will be seen in the short term."

"But in the long run, the pros outweigh the cons."

"So, we should strengthen cryptography development."

Everyone nodded and agreed with this person's statement.

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

Some people propose to develop computer hardware and create the country's own brand. All hardware should be 100% made in Xia.

This idea was rejected as soon as it was proposed.

This is too difficult and cannot be accomplished with the current Xia State technology.

Mainly high-performance graphics cards and low-nanometer chips, which Xia Guo cannot produce.

Although Xia Guo can produce medium-performance graphics cards and high-nanometer chips.

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

Most people who buy computers look at the performance first and then the brand.

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

And in the end, I found that the computer I bought ran too slow, and I would eventually replace it with a computer made abroad.

Others talk about developing software and building Xia Guo'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 the only computer systems in the world are Microsoft and MAC is that it is not 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 in the world can create software based on this system.

Otherwise, it would be useless to create a computer system.

Others talk about building powerful firewalls, intrusion detection systems, security detection systems, vulnerability scanning systems...

But otherwise, although these things are helpful for 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 hands."

In an instant, more than 80% of the people present raised their hands.

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

Sui Zuyun said: "Fifty-six people, forty-five people agree, more than half."

"Okay, passed, then we will strengthen the development of cryptography."

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

After that, everyone was talking in gibberish.

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

The research direction of cryptography was finally determined as 14 technical priority research areas and 13 important investment areas.

There are three main directions for researching cryptography.

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

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

Password mechanism, also called password system.

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

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

Just like, the cryptographic mechanism is a small town, the cryptographic algorithm is a store, and the certificate structure is the business license for opening a store.

The cryptographic algorithm and certificate structure are placed on the cryptographic mechanism to run the cryptographic algorithm.

Finally, when the meeting was about to be disbanded, Sui Zuyun said: "Convene a cryptography meeting."

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

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

"For this conference, we are going to gather all the geniuses and experts in mathematics and cryptography across the country."

"We must pool our efforts across the country to solve the information security crisis to the greatest extent possible."

"Okay, Mr. Sui!" said a person, he is the person who specializes in hosting the invitation list.

"The most important thing is that the identities of all people attending the meeting must be carefully verified, and some people with bad ideas must not be allowed to attend."

"Yes, Mr. Sui!"

…………

Zhonghu University!

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

Another half month later, it was early November.

Half of the research on elliptic curves has been completed, and it will take up to one month to complete the next half.

Ye Fei's office!

Everyone was sitting on the stool. Ye Fei was also sitting on the stool and said: "Everyone, based on the research between elliptic curves and Diophantus, we can study it from the ring k."

The full name of the study of ring k on Diophantus is called algebraic integer ring solutions on Diophantus.

Generally speaking, the Diophantine problem is unsolvable, and it is the tenth of Hilbert's 23 problems.

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

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

He talked for a full hour.

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

Ye Feidao: "Let's digest what I just said first."

After saying that, he stood up and walked out.

"Dean, why are you here?" Ye Fei said with a smile.

The dean smiled and said: "The number theory team has done a good job for you!"

Ye Fei chuckled 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, each of your team members made more than one million."

"I asked you to join the number theory group just because I wanted you to learn management skills so that you can later enter the school's management."

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

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

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

"Many people also inquired from me and wanted to join your group."

"How about it? Do you want to add more people?"

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

"If I take them out to do a project, the more people I have, the less money each team member will get."

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

"And for these people now, I have just enough projects to do, and everyone gets a lot of money."

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

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

"Of course not. How is your research on Gaussian conjecture going?"

"It's not bad. I've reached the end of the second question and it's almost finished."

"So fast?" The dean was shocked.

Then he said in amazement: "Ye Fei, with your research speed, it feels like the results of your research are right in front of your eyes."

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

The dean shook his head and said, "Let me tell you something."

"Say it!" Ye Feidao.

"How much research have you done on cryptography?"

Ye Feidao: "It's not bad!"

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

Ye Fei looked at the dean's serious expression and asked tentatively: "Is this important?"

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

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

He talked about more than fifty cryptographic studies.

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

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

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

"Not bad!" The dean nodded.

He pondered for a while and then said: "Do you want to study cryptography?"

"Uh..." Ye Fei said in surprise: "Cryptozoology?"

"Yes!"

"It's not that I can't do research, it's just that I'm studying Gaussian conjecture, so let's forget about cryptography!"

"If I study cryptography, it will greatly delay my study of Gaussian conjecture."

The dean looked around and whispered: "Well, there is a cryptography conference. You go and attend it. As for whether to study cryptography in the future, we will talk about it later!"

"Is it important?" Ye Fei said a little embarrassed.

He is not very willing to participate. The Gaussian conjecture has been studied for a long time, for more than a year, but it has not been completed yet.

He wanted to complete the research as soon as possible so that he could conduct further research.

"You'll know when you go there."

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

"When will you join?"

"Early next month, the attendees at this cryptography conference will gather talents from all universities and research institutes across the country. The standards are very high."

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

If something goes wrong, there must be a monster. 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 there must be benefits to participating, so I let you go."

The dean didn't know the specific information. He just received instructions from above asking Ye Fei to attend a cryptography conference.

"Okay!" Ye Feidao: "Where is the address?"

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

"OK!"

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

Shortly after the dean left, Ye Fei received the address from the dean.

One month later!

Ye Fei wrote on the whiteboard.

[Fix the 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 based on Matiyasevic's theorem. 】

[The proof of the elliptic curve is complete! 】

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

"We've reached another milestone."

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

They feel a sense of accomplishment every time they complete an academic study.

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

Ye Fei was also very excited. He had gathered everyone's strength and absorbed everyone's inspiration to research it together.

If there were no people present, he would not be able to research academic problems 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 Feidao: "Everyone, this research is over, let's take a break."

"Ah..." someone complained sadly: "Team leader, why are you taking a break again? Keep up the good work!"

"Team leader, are you going to take us on any project?"

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

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

"Hey..." Everyone sighed with regret.

Ye Fei smiled and said: "Don't be discouraged, everyone. If you really want to do a project, I have many projects on hand. When the Gaussian class conjecture in the virtual quadratic field is completed, I will take you to do one."

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

There are projects as small as hundreds of thousands to as large as several million.

So, don’t say that college teachers are poor.

The poor are all incompetent university teachers, and the capable university teachers are extremely rich.

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

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

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

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