"The main thing is the password algorithm, let me talk about the password algorithm first."

"As I said yesterday, I tend to use SM2 and SM4 to study the password algorithm."

"The security of the traditional password algorithm is based on the black box attack mode. In this attack mode, the attacker can only ..."

"The white box SM4 solution is facing differential calculation analysis ..."

"In the password algorithm, we should be divided into four -step research."

"Research on the preparation of knowledge, the study of the statistical characteristics of uniform random and reversible matrix on the N -order on GF2, the analysis of differential calculation analysis of the white box SM4 scheme and the improvement of the white box SM4 solution."

"The theoretical part is mainly to prepare knowledge. It is divided into SM4 packet password algorithm, white box SM4 solution and differential calculation analysis."

Academician Nan said: "Talk about the SM4 group password algorithm."

Ye Feidao: "The packet length and initial key length of the SM4 packet password algorithm are 128 bits ..."

After a long time, Academician Nan nodded: "Yes, I am relieved now, your theoretical aspect is very solid."

Academician Nan's heart is not simple, and Ye Fei is not easy, researching the theory, but he has a deep understanding of the knowledge of cryptography.

The most important thing is that Ye Fei is not the main study of cryptography.

But he has a deep understanding of cryptography.

This is amazing.

Ye Fei laughed: "After the prize, these studies are all the knowledge of digital theory. I was originally studying mathematics.

Academician Nan asked: "How do you understand for the S box?"

The white box is the study of the oval curve, which belongs to the knowledge of digital theory.

The S box is the research of group passwords, which belongs to non -linear knowledge.

Ye Feidao: "S box is an important non -linear component in the SM4 packet password algorithm. Use Toffoli door, CNOT door ..."

Academician Nan nodded secretly, and he liked Ye Fei more and more.

Talent, everyone likes it.

He said: "Very good, very good!"

Sui Zuyun asked: "Academician Nan, do you still need to ask?"

"No!" Academician Nan shook his head: "With Ye Fei's ability, you don't need to ask more."

"I hope the cooperation between us can study the cryptography as soon as possible to help the country."

Ye Fei laughed: "Okay."

Sui Zuyun looked at Ye Fei and asked: "Ye Fei, what do you need to say?"

"President Sui, will it be pulled to a fully closed place after doing a project and cannot contact the outside world."

Ye Fei has never been in contact with such a high -secret study, but he has never eaten pork and has seen pig running.

He has watched TV series and movies before. From the inside, he has been exposed to high -secret researchers and was pulled to a closed place. He could not contact the outside world for a few years.

A loved ones and friends can not meet for a few years.

Some people even thought that this person died.

Sui Zuyun couldn't cry and laugh: "Who tells you, where do you hear?"

"Isn't it?" Ye Fei asked: "I have played like this on TV!"

"Haha ..." Everyone laughed.

Sui Zuyun shook his head and laughed: "You should be taken seriously on the TV. Now it's not the past, and we will not pull you to a closed place. You can leave at any time in the experiment.

Fan, there is no thing in the laboratory. "

"Of course, before this, everyone must sign the confidentiality agreement."

"Ao!" Ye Fei was relieved, and he could leave, so his research at school can continue to do it.

You can go home with your parents for the New Year.

He is still young, but he doesn't want to see relatives and friends for a few years.

Even if his friend, if he disappeared for a few years, his parents would be very anxious.

He doesn't want to do so.

Ye Fei asked: "President Sui, where is the place of research?"

"Information Resources Research Center of Chang'an University of Technology."

Changan University of Electronic Science and Technology is the best university in Xia Guo's cryptography.

The Information Resources Research Center is a place to study cryptography, and it is also the best cryptography research center in Xia Guo.

Ye Fei nodded, Changan was not far from Zhonghu, he could return to Zhonghu often.

"Do you still ask?"

"No more." Ye Fei shook his head.

Sui Zuyun said: "Okay, in this case, I now announced that the study was set as 1109 experiments.

"All mathematicians and cryptologists who participated in the conference will join the 1109 experiments. Later, there will be talents in cryptography of various universities across the country to join."

"A week later, you report to the Information Resources Research Center of Changan University of Technology."

"yes!"

After that, Sui Zuyun convened all mathematicians and cryptologists, and told the 1109 experiment again.

Then everyone signed a confidentiality agreement, and then everyone left here.

After returning to Zhonghu University, Ye Fei summoned the members of the team.

Ye Feidao: "Everyone, I may temporarily leave the number theory group."

"Ah ..." The group members looked at Ye Fei in surprise.

Someone called: "The team leader, where are you going? Let's follow you."

Following Ye Fei's money, Ye Fei left the number theory group, and they had no money to earn.

The two of Amata looked at Ye Fei anxiously, Amarta said: "Ye, you are gone, what should we do?"

Ye Fei looked at the two people: "You stay at Zhonghu University with peace of mind, I will not leave for too long, and soon come back."

"Of course, because I want to do other jobs, I can't fully serve the study of the Duju Group, but I can work part -time."

"Every time I come back, I will arrange a research direction for you."

"Huh ..." Everyone heard this, and his heart was relieved.

It turned out not to leave, just because I have to do other jobs.

A part -time work group, this situation is very common.

Some professors, because of their outstanding ability, work part -time multiple jobs.

For example, Ye Fei led the Digital Group to do a Gaussian conjecture.

Managers only need to indicate the direction of research, the most important and difficult part of research.

The rest of the simple and complex research are all handed over to the researcher.

Amara thought for a while: "Okay, we are waiting for you at Zhonghu University. Anyway, I don't study Gauss's conjecture, and I won't leave."

Amata really loves to die, there are food and research.

He has studied with Ye Fei for the past few months and caught up with his studies in the past year.

If he leaves, he needs to spend more time to study.

Therefore, he might as well study with Ye Fei.

Ye Fei looked at Baraz and asked, "Balaz, how about you?"

Baraz Road: "Almata is fine, I'm naturally no problem, I also stay at Zhonghu University."

Alta stays at Zhonghu University because of food and research.

Barlaz stays at Zhonghu University because of beauty and research.

Some team members asked: "The team leader, what are you going to do?"

Ye Feidao: "This can't tell you, you are all scientific researchers, you should know that some things cannot be said to the outside world."

Everyone immediately shut up, as scientific researchers, they knew the rules.

Some things can't be done, some words can't be said.

Ye Feidao: "I will come back every half month to guide your research direction. I hope that the days when I am absent can continue to accelerate research."

"Okay, team leader!"

Ye Feidao: "I leave, naturally need someone to manage the team."
