From university academician to chief academician

Chang'an University of Electronic Science and Technology Information Resources Research Center, Office!

Ye Fei, Nan Guodong and Cheng Jian were sitting among them, discussing cryptography research.

Nan Guodong is the person in charge of cryptography research. He first said: "Tell me about the research of your respective groups."

Cheng Jian looked at Ye Fei. He admired Ye Fei's ability, so when the two of them were exploring and researching, Ye Fei had a more important say in it.

Nan Guodong said: "Professor Ye, you speak first."

"Okay!" Ye Feidao said: "My team's research has been completed for less than half. It has just finished the research on the SM4 algorithm. Next is the research on the wheel function. It is expected to be completed early next year."

Nan Guodong nodded with satisfaction, looked at Cheng Jian and said, "Professor Cheng, our group is here!"

Cheng Jian said: "My group's research speed is similar to Professor Ye's. We have just completed the signature verification in the SM2 cryptographic algorithm. The next step is to study the security definition."

"It is also expected to complete the study early next year."

Academician Nan Guodong nodded with satisfaction.

Originally, their research speed would not be so fast, but he did not expect Ye Fei to bring him such a big surprise.

With Ye Fei deriving the main formula, their research speed was greatly accelerated.

Nan Guodong said: "It seems that our research has been completed less than half, and the most basic framework has been created. At this time, we can conduct a wave of small tests, which can be regarded as the first wave of tests."

The study of cryptography is different from other research.

Cryptography needs to go through many tests during research. Through testing, problems can be discovered and corrected later.

Nan Guodong looked at the two of them and asked, "What do you think?"

Ye Fei smiled and said: "Academician Nan, you are a professional, I will listen to you."

Cheng Jian smiled and said: "Professor Ye is right, Academician Nan, I listen to you."

"You two!" Nan Guodong shook his head funnyly: "Okay, let's test it."

"In this test, each of our groups will take out the research and conduct data docking to form a cryptography system. We will call this system Yuan."

A circle means there are no corners, and the absence of corners means there is no blind spot, and you cannot retreat or get out when you attack.

"Round?" Ye Fei and the others thought to themselves.

Then the two of them nodded secretly: "Yes, a very appropriate name."

Nan Guodong said: "Also, I don't plan to use simulation tests, but actual combat tests." "

He looked at Ye Fei and asked, "Professor Ye, what do you think?"

Ye Fei thought for a while and then said: "It's not impossible if we conduct a practical test. I'm very confident in the attack capabilities of the circle studied by our team."

Their group’s research is mainly based on SM4, supplemented by quantum computing.

The ability of quantum attacks, I believe even people who do not understand computers and mathematics know that the ability of quantum attacks is very powerful.

Common attacks are attacks in a single or a small number of sequences.

The quantum attack uses a human sea tactic, and the attack sequence is very large.

You may be very strong, but two fists are no match for four hands. Quantum attacks can drown you even if you spit in every sequence.

Unless the opponent can also create a quantum attack, the two sides will fight each other.

But there is no need to worry, Ye Fei and the others are using super computers.

Supercomputing can greatly speed up the operation of cryptographic algorithms.

Quantum computing coupled with supercomputing may mean that the number of opponents is about the same as ours, but the speed is definitely not as fast as ours.

Unless the other party also uses super calculation.

People who attack cryptographic algorithms are generally hackers. Hackers are generally poor, and the proportion of them using supercomputers is very small.

Besides, even if the other party uses supercomputer, can the quality of their supercomputer be compared with the country’s supercomputer?

This is obviously impossible!

Ye Fei looked at Cheng Jian and said, "Professor Cheng, what is the defensive effect of the circle studied by your group?"

Cheng Jian said: "Don't worry, our team's research is mainly based on SM2, supplemented by cloud computing."

"The defense mechanism is very strong. If the opponent attacks, there is no need to use the attack mechanism. The opponent may not even be able to break our skin."

The defense mechanism of Cheng Jian's team is like a maze.

The entire defense mechanism is changing every second. As soon as a door is unlocked, the entire system changes. Then when a door is unlocked, the entire system changes again.

In other words, every time a door is broken, the entire system changes.

And, every change is different.

There are changes in moving forward, and the way back has become a strange road. When you go back, you have to unlock the door again.

At this time, the attacker seems to be trapped in a spider web. The more he struggles, the more complicated the situation becomes.

And the defense mechanism just traps them, leaving the attacker behind.

Then the attack mechanism studied by Ye Fei's team took action.

Ye Fei nodded and asked, "Academician Nan, how can we actually fight?"

"I am ready to cooperate with Alibaba and let Alibaba's programmers attack our circle."

"Alibaba has the strongest security defense system in China."

"When it comes to defense systems, there is no one in the entire Xia Kingdom that is stronger than this company among private companies."

"With such a strong defense system, their programmers are also very strong in attack."

Ye Fei nodded.

He agrees with this. The reason why Alipay has not been breached so far is because Alibaba has a very strong security defense system.

Being able to have such a powerful security defense system is naturally due to the company's programmers.

For such a powerful programmer to say that he can only defend but not attack is simply nonsense.

Ye Fei smiled and said: "If it is Alibaba's programmers, we must treat them well and not let them easily break our cryptographic algorithm. Then it will be a joke."

Ye Fei is not worried, Nan Guodong cannot invite Ali.

As an academician, he can do many things within the Xia Kingdom.

Cheng Jian nodded and said, "Yes."

Nan Guodong smiled and said: "Don't be too burdensome. This is just a test. Even if it fails, it doesn't matter. We can still find shortcomings and make corrections."

Ye Fei smiled and shook his head: "Even if it is a test, it is also a test of our performance. We cannot fail easily!"

"If we fail easily, what will the other party think of us?"

"We belong to the national laboratory after all!"

"We can't let them underestimate the national laboratory."

"I would rather die standing than live sitting down."

"Even if you fail, you still have to let the other side lose a piece of flesh."

"Professor Ye is right." Cheng Jian said: "I don't want to be looked down upon by others. This is my first job after returning to China, and I don't want my grades to be too bad."

"Okay!" Nan Guodong expressed his frustration at the enthusiasm of these two young people. This was just a test, so there was really no need to take it too seriously.

Of course, he didn't take it seriously just because he had encountered it too many times.

Coupled with getting older, the enthusiasm has faded.

Ye Fei and Ye Fei are still young people. If young people are not passionate, are they still young people?

Ye Feidao: "Academician Nan, when will the test be conducted?"

Nan Guodong said: "Half a month later"

Ye Fei thought for a while and then said: "Okay!"

Cheng Guodong said: "I think it's okay too."

Nan Guodong said: "Do you have anything else to ask?"

"No more!" The two shook their heads.

"Then let's break up!"

After saying that, the three people left the office, returned to their respective groups, and announced the test in half a month.

Ye Fei looked at his team members and said, "Everyone, please connect the data with the other two teams in this half month. We will test it with Alibaba's programmers in half a month."

"This test is a test of our half-year research."

"You don't need to be too nervous. This is just a small test. It doesn't matter if it fails."

Although Ye Fei wants to win, he wants to make his team members feel relaxed so that everyone does not have to bear too much burden.

When the team members heard this, they felt much more relaxed.

Alibaba is one of the top Internet companies in Xia State. Many of the programmers in the company are among the best in the country. Some of them are also very powerful internationally.

Faced with cyber attacks from these programmers, they still feel a certain amount of pressure.

In the next half month, the three groups will connect the data to deal with Ali's attack half a month later.

Half a month later!

The supercomputing room of the Information Resources Research Center!

The supercomputer host of the Information Resources Research Center is connected to the supercomputer of the National Supercomputing Chang'an Center, which is one of the top supercomputers in Xia State.

At this time, many researchers were sitting in front of the computer, operating the computer quickly and inputting many codes and data.

The test has not started yet, it is the preparation stage.

The three of them stood together. Ye Fei asked, "Academician Nan, when will the test start?"

Nan Guodong said: "It is up to us to decide when to start. When our side is ready, Ali's side will attack."

"Yeah!" Ye Fei nodded.

After more than an hour, all preparations were done.

Nan Guodong looked at the researchers present and asked, "Are you all ready?"

Everyone stood up from their seats and said, "Ready."

Nan Guodong said: "Okay, let's get started."

After speaking, he took out his mobile phone, called Ali, and said, "Mr. Yang, we are ready here."

"OK!"

Soon, the supercomputer showed that the system was under attack.

Everyone looked nervously at the supercomputer screen, which displayed rows of countless green numbers and several red numbers.

The more green numbers there are, the more programs in the circle are started.

The more red numbers, the more programs in the circle that have been cracked.

Ye Fei saw the red numbers appearing just after being attacked, and sighed in his heart: "As expected of Ali, he cracked several programs in less than a minute."

Cheng Ji'an nodded with satisfaction: "Very good, my defense mechanism has only been broken a few times. I'm already very satisfied."

Nan Guodong was also very satisfied and said: "This system is very good, and Ye Fei takes the greatest credit here. The core part of the circle is the cryptographic algorithm, and the main formula of the cryptographic algorithm was derived by Ye Fei."

"All research is also conducted around the main formula. As long as the main formula is good, the cryptographic algorithm developed is good. If the cryptographic algorithm is good, the system will be strong."

"Huh?" The three people's eyes lit up: "The offensive mechanism has begun to activate."

In just the blink of an eye, the red numbers quickly disappeared and were occupied by green numbers.

"This..." Nan Guodong was shocked: "So weak? He was repelled in less than ten seconds, right?"

"No, it shouldn't be said to be weak, but rather the offensive mechanism studied by Ye Fei's team is too strong."

Cheng Jian saw all the red numbers disappear in less than half a minute, and he was surprised and said: "This is too strong!"

Several of the defense mechanisms studied by his team were breached in less than a minute, while the attack mechanism of Ye Fei's team was able to repel incoming enemies in less than ten seconds.

If you don’t compare, you don’t know. A comparison will make a judgment!

Hangcheng, Alibaba, in a host room of the supercomputing center!

Many programmers sit in front of the computer and type quickly on the keyboard.

These programmers are all programmers from Alibaba Damo Academy.

All of Alibaba's top programmers are concentrated in DAMO Academy. This department is also very good. Speech intelligence, language technology, machine vision, and decision-making intelligence are all developed by this department.

This department is managed by Mr. Yang. At the request of Academician Nan to attack their circle, Mr. Yang gathered many programmers with the strongest offensive capabilities to attack Academician Nan's circle.

"Manager Xu, we have entered."

Manager Xu, who was walking among the programmers, smiled and said: "Very good, focus your firepower on me and attack the other side. We must defeat the opponent. Mr. Yang said, if you defeat us, give us a red envelope."

"Okay!" Everyone said enthusiastically.

Manager Xu saw that the battle was going well and walked out of the computer room.

Standing outside the door was a middle-aged man with his hands behind his back and wearing glasses, looking at the scenery outside through the window.

"Mr. Yang, we have broken in." Manager Xu walked up behind Mr. Yang and said, "Although it is difficult, it went smoothly."

"Yeah!" Mr. Yang nodded: "But don't attack too fast, and let it go a little bit. After all, the opponent is an academician, and the other party just came to us for testing, so we can't do anything too ugly. The other party can’t save his face.”

"Okay, Mr. Yang!" Manager Xu said, "I will instruct the people below to release the water at the appropriate time."

"Manager Xu..." Suddenly, a man ran out of the computer room and shouted, "Oh no, we have been repelled."

"Repulsed?" Manager Xu asked, "What are you making such a fuss about? Isn't this normal? Keep fighting!"

The visitor grimaced and said, "We thought too, but the opponent's attack mechanism is too strong. As soon as they entered, they were repulsed, and then they entered again, only to be repelled again."

"We attacked more than a dozen times, but were repulsed in less than ten seconds each time."

"So strong?" Manager Xu said in surprise: "Let's go and have a look."

Mr. Yang frowned and was shocked: "Is he so strong?"

You know, these people are the ones with the strongest offensive capabilities in Alibaba's computer technology.

Even if you put them internationally, these people are also technical masters.

But now he has been repelled many times by the opponent.

After saying that, he also walked into the computer room, wanting to see the other party's ability.

At this moment, the computer room was in a state of rage. Seeing themselves being repelled again, everyone almost smashed the keyboard in anger.

After looking at it for a moment, Manager Xu exclaimed: "What kind of offensive mechanism did the opponent use to make it so powerful?"

"No!" He shook his head and said, "Isn't it possible that the other side organized a group of people to fight back against us?"

Mr. Yang shook his head and said: "No, the other side wants us to test their system, so it will be impossible to organize a group of people to fight back against us."

"But this is too strong!" Manager Xu said: "The other party is just a system, and we are still alive, but we can't break into it."

"Especially the opponent's offensive mechanism is too strong."

Mr. Yang frowned and said, "It's indeed very strong."

He shook his head again and said: "Since we can't attack it, let me go and ask what's going on?"

"Even the offensive mechanism cannot be so strong."

"If there is such a strong offensive mechanism, our company will fight for it."

After saying that, he walked out of the computer room and took out his phone to call Nan Guodong.

"Academician Nan, your system is very powerful!" Mr. Yang said with a wry smile: "Our programmers can't break into it at all. I think this test will be over!"

"Okay!" Academician Nan said, "Thank you for your company's help."

"Whatever you are talking about, you have also helped our company, and it is right for us to help you."

"By the way, Academician Nan, why is your attack mechanism so strong? My programmers attacked for more than ten minutes, but were kicked out every time they entered."

"I don't know about this. I didn't develop this." Academician Nan said, "If you want to know, I can ask the R\u0026D person to explain it to you."

"Then I'll trouble you, Academician Nan."

"It's okay." Academician Nan said, "I can't explain it over the phone. I'll let him have a remote voice and video chat with you!"

"OK."
