From university academician to chief academician

The cryptographic algorithm competition is scheduled for three days. During these three days, Ye Fei and the others can make some preparations.

After the meeting, everyone checked into the manor.

The manor is very large, and it is no problem for more than 300 people to stay there. Two people share a room.

Ye Fei and Yue Fei lived together. After dinner, Ye Fei was in the room writing mathematical algorithms for the competition three days later.

Ye Fei also knows about NIST.

NIST was created by the National Institute of Standards and Technology to conduct basic and applied research in mathematics, computers, physics, biology and engineering.

Cryptographic algorithms belong to the intersection of mathematics and computers.

Therefore, it is naturally possible to study cryptographic algorithms on NIST.

Since it is just a competition and not a major research, NIST is adopted.

If it is a major research, no country will use NIST.

Because NIST was created by North Korea, only fools would put major research on NIST.

Ye Feixin said: "SM2 is a national secret algorithm and an elliptic curve public key cryptography algorithm."

"And SM4 is also a national secret algorithm and a block cipher standard."

"SM2 and SM4 are both commercial cryptographic algorithms..."

"SM2 uses an elliptic curve structure, while SM4 uses a nonlinear iterative structure."

As he spoke, Ye Fei wrote down the derivation formula on the paper.

[R={R1, R2,.,Rδ} represents the smart grid of δ regions...]

After an unknown amount of time, Yue Fei walked in from outside.

He sat next to Ye Fei, read what Ye Fei had written for a while, and said, "Most of what you wrote is based on elliptic curve knowledge!"

"Yeah!" Ye Fei said while writing without raising his head, "Yes."

"Most cryptographic algorithms use number theory. Gaussian conjecture is one of the most important conjectures in number theory. It is very suitable to use Gaussian conjecture to study cryptographic algorithms."

"Elliptic curves are one of the main parts of Gaussian conjecture. There is nothing wrong with using elliptic curves to study cryptographic algorithms!"

Yue Fei smiled and said: "Of course it's no problem. I'm just lamenting that most of your research on cryptographic algorithms uses elliptic curves."

"After all, I haven't started researching this area yet."

Ye Feidao: "Then you have to speed up. Elliptic curve is really a beautiful thing."

"You will see the beauty of mathematics."

Yue Fei smiled helplessly and said: "Do you think everyone can research as fast as you?"

"The speed of your research is beyond what humans can achieve. It's simply abnormal."

Ye Feidao: "Hey... you can't curse people. I am fast, but that doesn't mean I'm not a human being!"

Yue Fei shook his head and said: "I won't bullshit you about this anymore, you must be very nervous now!"

"Why am I nervous?" Ye Fei shook his head and said: "To me, this is the direction of my past research. I have something in my mind, so I am so nervous!"

"Aren't you nervous?" Yue Fei was shocked: "Don't you know who the two people competing with you are?"

"Who is it?" Ye Fei looked up at Yue Fei.

"Cao Wencan and Fang Yongchang, one of them is a full professor at Peking University and the other is a full professor at Shuimu. They are both nationally renowned cryptography experts and executive directors of the Xia State Cryptozoology Society."

"In terms of cryptography, they are not the best."

"But you can't underestimate them either."

"You don't mainly study cryptography. It's definitely okay for them to abuse you in cryptography."

"Haha..." Ye Fei chuckled: "In this regard, I want to correct your mistakes."

"First of all, cryptography is not the study of passwords, but mathematics."

"In the field of mathematics, as one of the mathematicians, I am not sure who will abuse whom!"

"Haha..." Yue Fei gave a haha ​​smile, not believing Ye Fei's words.

Cryptozoology is the study of mathematics, but the field of mathematics is very broad, and a small problem can last a lifetime.

For example, the elliptic curve in Gaussian conjecture can be expanded infinitely.

The combination of elliptic curves and cryptography, the combination of elliptic curves and algorithms, the combination of elliptic curves and data encryption, the combination of elliptic curves and blockchain...

Mathematics is such a huge field, and even God cannot do it if he wants to study all aspects thoroughly.

Therefore, every mathematician specializes in one part of his research.

Ye Fei is not proficient in cryptography research. On the other hand, Cao Wencan and Fang Yongchang have been studying cryptography their entire lives.

From this point of view, anyone with a discerning eye can see that Ye Fei and Cao Wencan have no chance of winning when competing in cryptography.

But what everyone doesn't know is.

Ye Fei is not proficient in cryptography, but his research on number theory is the result of the research of many mathematicians.

Since he started studying number theory, he has participated in many large and small conferences and explored number theory problems with many mathematicians.

And these people have absorbed much of their knowledge of number theory.

There are so many people, so much knowledge of number theory, and the content is very large.

Cryptozoology studies number theory. With his vast knowledge of number theory, he would not be able to defeat these two people.

He could throw the system away.

Yue Fei said: "Ye Fei, you don't know how powerful these two people are."

"Cao Wencan and Fang Yongchang are equally capable. Let me just say Cao Wencan!"

"Cao Wencan enjoys a special allowance from the National Academy of Sciences. He is an outstanding expert in Kyoto City and a famous scholar in the field of number theory and cryptography. He has long served as a member of the Academic Committee of the State Key Laboratory of Information Security and the executive director of the Xiaguo Cryptozoology Society."

"Achieved internationally influential results in basic mathematics and cryptography research, won the National Natural Science Award and the National Science and Technology Progress Award three times, and was awarded the title of national-level young and middle-aged expert with outstanding contributions."

"He has presided over more than ten national key projects, published more than 30 scientific research papers, 5 monographs, and 2 patents."

"The research team he led cooperated with RSA, a famous data security company in North America, and successfully developed relevant software for elliptic curve public key cryptography, which became part of the company's BSAFE security software."

Ye Fei looked at Yue Fei in shock and said, "How do you know him so well?"

Yue Fei smiled and said: "Because he and I are from the same school. He is my idol. The reason why I went to Kyoto University to teach is partially related to him."

"You don't know how deep his research in number theory is, and Fang Yongchang's ability is no weaker than him, so you can't defeat these two people."

Ye Fei shook his head in his mind, thinking that he was a fan.

Your idol is so awesome!

Is your idol invincible?

No one is perfect, no one always wins, and one day he will fail.

Ye Feidao: "What if I can defeat them?"

Yue Fei sneered: "If you can defeat them, I will be your little brother."

Ye Fei looked at Yue Fei and said in a joking tone: "I don't want a brainless little brother like you. If I can defeat them, you will come to Zhonghu University. How about it?"

Yue Fei's ability is quite strong. When he came to Zhonghu University, to be honest, his talents were compromised.

If it were normal times, he would definitely not come to Zhonghu University.

But through a bet, maybe he can be lured.

He doesn't want to do anything about poaching people either.

But he found that there was no one at Zhonghu University!

And if he wants to conduct academic research, he must have people, so he can only poach people from other universities.

Yue Fei smiled and said, "Okay, no problem."

How could Ye Fei defeat his idol? Therefore, it was impossible for Ye Fei to win this bet.

A smile flashed in Ye Fei's eyes.

Regarding the match between Cao Wencan and Cao Wencan, he was very sure of victory.

So, Yue Fei, come to Zhonghu University!

Ye Feidao: "Let's write a contract so that you won't admit it later."

"Who doesn't admit it? Am I that kind of person?" Yue Feidao said.

"Are things like this rare in today's world?" Ye Fei asked.

"Okay!" Yue Fei waved his hand and said impatiently: "You write the contract and I'll sign it."

Ye Fei quickly wrote the contract and Yue Fei signed it.

After signing the contract, Ye Fei put it away. This was equivalent to Yue Fei's deed of betrayal, and he must put it away.

Ye Fei said: "Okay, don't disturb me, I'm busy."

Three days later!

It was still the same big room, but there were three computers placed in front of the many seats.

The hosts of these three computers are small supercomputer hosts.

Compared with ordinary home computers, it runs tens of thousands of times faster.

This is also a scenario that simulates the future research on cryptographic algorithms. When the time comes to study operating machines, it will be supercomputing.

The three of them, Ye Fei, each sat in front of a computer and entered the mathematical algorithms they had written in the past few days.

NIST is originally a framework of cryptographic algorithms, and it is empty inside.

By inputting different mathematical algorithms, NIST can form cryptographic algorithms with different capabilities and functions.

This is like a robot that can execute different instructions by inputting different programs.

Cryptographic algorithms are a combination of mathematics and computers.

Ye Fei's mathematical algorithm is mainly based on elliptic curves and supplemented by nonlinearity.

The computer algorithms are SM2 and SM4.

It is a hybrid cryptosystem based on the SM2 elliptic curve digital signature algorithm and the SM4 block cipher algorithm.

It has the functions of ultra-high defense performance, fast response speed and multi-verification.

After a long time, the three of them stopped what they were doing.

Sui Zuyun said: "Are you ready?"

"Okay." The three said.

"Then let's start!" Sui Zuyun said.

After speaking, he nodded to the person next to him.

The man took out the phone, pressed a few buttons, put it to his ear and said, "Start!"

Not long after he finished speaking, the computers of Ye Fei and the others suffered numerous external attacks.

The NIST software in the computer runs automatically to block external attacks.

Seeing the password algorithm in the three people's computers starting to run, the people below started talking.

"Tell me, Cao Wencan or Fang Yongchang, who can win?"

"Who knows? The abilities of these two people have always been between equals. Cao Wencan won once and Fang Yongchang lost once. Soon after, Cao Wencan lost once and Fang Yongchang won once."

"Hey...I heard that these two people studied under the same teacher."

"Well, yes, it's Mr. Pei Yuan, the president of the Cryptozoological Society."

"Pei Yuan, is that Pei Yuan who studied under Mr. Hua Luogeng?"

"It's him."

Pei Yuan, who studied under Hua Luogeng and was one of the first batch of visiting scholars from the Xia Kingdom to Beili, went to the Department of Mathematics of Princeton University for two years to study modular forms with Professor Shimura, the master of number theory.

And he has made extraordinary achievements in the study of the fundamental theorem of modular form.

Professor Shimura was full of praise for Pei Yuanshi.

An evaluation material about Pei Yuan's achievements said that this achievement is one of the most important achievements in the theory of modular form in the past fifteen years.

After Pei Yuan returned to China, he became an associate researcher at the Institute of Applied Mathematics of the Xia Academy of Sciences, a professor at the Graduate School of the Xia Academy of Sciences, a professor at Kyoto University, director and deputy director of the Academic Committee of the State Key Laboratory of Information Security, and director of the Information Security Research Institute of Kyoto University.

Until now, he has become the first and second chairman of the Xiaguo Cryptozoology Society.

"Since we studied under the same teacher, why are our relationships so bad now?"

"I heard that it was because of a woman that they liked the same woman, so they fought back and forth, but the funny thing is, neither of them got the woman in the end, and the woman ended up marrying a physics guy. "

"Mathematics and physics? Haha..."

"Do you think Ye Fei has a winning chance?"

"Ye Fei? Ye Fei is indeed very powerful and can achieve such great achievements at such a young age, but he studies mathematics and is not specialized in cryptography. He should have no chance of winning."

Many people nodded inwardly.

Indeed, they had not heard that Ye Fei was proficient in cryptography.

On the other hand, the other two people specialize in cryptography.

How can a non-professional win over a professional.

After that, everyone continued to discuss whether Cao Wencan or Fang Yongchang won.

Since the two have equal abilities and similar records in the past, no one can be sure who of the two will win.

Sui Zuyun said to the people beside him: "Who do you think among the three of them will win?"

Someone said: "I think it will be Cao Wencan. His algorithm runs very fast, and with fewer logic gates, it can defend against external attacks very well."

"Hey..." someone objected: "I think it will be Fang Yongchang. Fang Yongchang is right. Attack is the best defense. The ESF cryptographic algorithm has very strong offensive capabilities."

Mai Yuan from the Department of Education said: "Where's Ye Fei? Don't you think highly of Ye Fei?"

Many people looked at each other and shook their heads.

Although the cryptographic algorithm Ye Fei said was very good, he did not specialize in cryptography, so they were not optimistic about it.

"I'm optimistic." Geng Ye from the Department of Science and Technology said, "I like Ye Feike very much. Even if he doesn't specialize in cryptography, I believe in his abilities."

"He is a genius, and genius cannot be explained by ordinary methods."

Someone asked: "Are Cao Wencan and Cao Wencan not geniuses? Anyone who can achieve certain achievements in the field of mathematics, who is not a genius?"

Many people nodded, indeed.

Mathematics is a field of genius. Anyone who can achieve certain achievements in mathematics is a genius.

"Academician Nan, what do you think?" Sui Zuyun looked at Academician Nan.

"I think no one can say who will win or lose between them. The same goes for Ye Fei. He may not be good in other fields of mathematics, but in the field of number theory, I am very optimistic about him."

"Of course, I am also very optimistic about cryptography."

Academician Nan once read Ye Fei's number theory paper and was very interested in it.

After reading it, I discovered that the author of the paper was named Ye Fei.

He didn't know who Ye Fei was, but later investigation found that he was only twenty-five years old.

Of course he was astonished that he could write such a paper at the age of twenty-five.

Everyone looked at Academician Nan in surprise, and someone said cautiously: "Academician Nan, do you think Ye Fei can win?"

"Of course!" Academician Nan nodded: "Is it a competition? No one can tell who will win until the end."

"The ancients used to fight against the odds, win with less and win with more, and turn against the enemy."

"So, it seems that Ye Fei is weak, but who can be 100% sure that he can't win?"

Many people shook their heads inwardly and disagreed with Academician Nan's words.

Logically speaking, Ye Fei is not a cryptography professional, so how could he win against a professional?

This is like if a basketball fan goes to play basketball with an NBA player, can a basketball fan beat an NBA player?

This is obviously impossible.

"Okay!" Mai Yuan said with a smile: "I agree with Academician Nan. Ye Fei does not specialize in cryptography, but who can say that he will not win?"

Geng Ye said: "I also agree with what Academician Nan said."

After saying that, he looked at Sui Zuyun again and said, "Mr. Sui, who do you like?"

Sui Zuyun smiled and said: "Since the three of you are optimistic about Ye Fei, then I am also optimistic about Ye Fei."

Someone suggested: "In that case, let's make a bet. Whoever guesses loses will treat the winner to dinner."

"No problem." Everyone said.

While speaking, the situation on the field suddenly changed.

I saw the computer in front of Fang Yongchang suddenly crashed.

After Cao Wencan saw it, he laughed loudly and said: "Lao Fang, you lost, I won, haha..."

"I told you that yours was no good, but you still didn't believe it, and you told me that offense is the best defense. Look, what's going on now!"

Fang Yongchang's face was livid, he glared at Cao Wencan angrily and said, "It's amazing that you won. Don't forget, you haven't won yet."

"Why didn't I win..." Cao Wencan looked at Ye Fei's computer and said in surprise: "Ye Fei, why haven't you lost yet?"

Ye Fei looked at him speechlessly and said, "Isn't it normal that I didn't lose?"

Many people were surprised that Fang Yongchang had lost, but Ye Fei hadn't lost yet.

You know, Fang Yongchang is a professional!

If he loses now, it means that Fang Yongchang is not as good as Ye Fei in terms of cryptographic algorithms.

But this is not scientific!

Yue Fei was very surprised and thought to himself: "I'll go, is Ye Fei so awesome? He can actually defeat Fang Yongchang."

He looked at Cao Wencan again and thought: "Professor Cao, you must hold on for me, you can't lose!"

At the leadership table, someone said in surprise: "Did Fang Yongchang lose?"

Another person said: "I didn't expect him to be the first to be eliminated."

Someone looked at Ye Fei and said, "Ye Fei can do it. Fang Yongchang is out. He's not out yet. He should be next."

Everyone nodded and agreed with this statement.

But as soon as he finished speaking, Cao Wencan's computer crashed.

"Uh..." the speaker said in astonishment: "Cao Wencan also lost?"

Mai Yuan laughed loudly and said: "Haha... I just said Ye Fei can do it. Look, now only Ye Fei is left."

He looked at the others and said: "Everyone, do you still remember your bet? Treat me. I tell you, I won't eat anything cheap. At least the per capita consumption is more than 5,000."

Everyone shook their heads helplessly.

Geng Ye looked at Sui Zuyun and said, "President Sui, the winner has been decided, is it over?"

Sui Zuyun shook his head and said: "The competition is secondary. I mainly want to see the performance of the cryptographic algorithm."

"Ye Fei's computer hasn't been hacked yet. I want to see how long his computer can last."

After that, everyone waited for an hour.

Many people thought: "It should be over soon!"

Waited another hour.

Many people thought: "It should be soon!"

Still waiting for an hour.

"When will it end?"

Wait another hour.

"Fuck...when will this take place?"

Then they waited from morning to afternoon, and from afternoon to evening.

Sui Zuyun shook his head and said: "Forget it, no more waiting, let's end it!"

After speaking, he stood up and said: "I declare that this competition is over, and the cryptographic algorithm research direction will be SM2 and SM4."

"Huh..." Everyone took a long breath in their hearts, and it was finally over.
