From a university student to a chief academician

Chapter 129 Cryptography System Circle VS Ali Programmer

Changan University of Electronic Science and Technology Information Resources Research Center, Office!

Ye Fei, Nan Guodong, and Cheng Ji'an sat in it, 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 Ji'an looked at Ye Fei, he admired Ye Fei's ability, so when the two explored and researched, Ye Fei's right to speak was even more important.

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

"Okay!" Ye Fei said: "My group's research has been completed for a little while, and the research on the SM4 algorithm has just been completed, and the next step is the research on the round function, which is expected to be completed early next year."

Nan Guodong nodded in satisfaction, looked at Cheng Ji'an and said, "Professor Cheng, where is your team?"

Cheng Ji'an said: "My group's research speed is about the same as Professor Ye's. I have just completed the signature verification in the SM2 cryptographic algorithm, and the next step is to study the security definition."

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

Academician Nan Guodong nodded in satisfaction.

Originally, their research speed would not be so fast, but they 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 for a little while, and the most basic framework has been built. 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 studies.

Cryptography has to go through multiple tests in research, and problems can be found through tests, and then corrected.

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

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

Cheng Ji'an smiled and said, "Professor Ye is right, Academician Nan, I will listen to you."

"You two!" Nan Guodong shook his head amusedly: "Okay, then test."

"For this test, each of our groups will take out the research for data docking to form a cryptographic system. We call this system Circle."

A circle means no corners, and no corners means no dead ends, no retreat, no exit.

"Round?" Ye Fei thought to himself.

Then the two nodded secretly in their hearts: "Not bad, a very appropriate name."

Nan Guodong said: ""And, 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 pondered for a while and said, "It's not impossible to conduct an actual combat test. I'm very confident in the round and attack capabilities of our team's research."

The research of their group is mainly based on SM4, supplemented by quantum computing.

The ability of quantum attack, I believe that even people who don't understand computers and mathematics know that the ability of quantum attack is very powerful.

Common attacks are single or few sequences.

The quantum attack is based on human sea tactics, and the attack sequence is very large.

Maybe you are very strong, but two fists are no match for four hands. Quantum attack can drown you even if you spit in each sequence.

Unless the other party can also create a quantum attack, the two sides will bombard each other.

But it’s not scary, Ye Fei and the others are using supercomputers.

Supercomputing can greatly speed up the operation speed of cryptographic algorithms.

With quantum computing and supercomputing, the number of opponents may be about the same as your own, but the speed is definitely not as fast as your own.

Unless the other party also uses supercalculation.

The people who attack the cryptographic algorithm are generally Hei Ke, and Hei Ke is generally relatively poor, and the proportion of them using supercomputers is very small.

Besides, even if the other party uses supercomputing, can the quality of their supercomputing be compared with that of the country?
This is clearly not possible!

Ye Fei looked at Cheng Ji'an and said, "Professor Cheng, what is the defensive effect of the circle that your team studied?"

Cheng Ji'an 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, the attack mechanism does not need to be shot. The opponent may not even be able to break our skin."

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

The entire defense mechanism is changing every second. Just unlocking a door, the entire system changes, and then unlocking a door, the entire system changes again.

That is to say, every time a door is broken, the whole system changes.

And, every change is different.

The way forward has changed, the way back has become an unfamiliar way, and the door must be unlocked again when going back.

At this point, the attacker seemed to be trapped in a spider's web, and the more he struggled, the more complicated the situation became.

And the defense mechanism just traps them, keeping the attacker in.

Then came the attack mechanism researched by Ye Fei's team.

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

"I'm going to cooperate with Ali Company and let Ali's programmers attack our circle."

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

"In terms of the defense system, in the entire Xia Kingdom, among private companies, there is no stronger company than this company."

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

Ye Fei nodded.

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

Such a powerful security defense system is naturally due to the company's powerful programmers.

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

Ye Fei said with a smile: "If it's Ali's programmers, we have to treat them well, and we can't let them easily break through our encryption algorithm, and then it will be a joke."

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

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

Cheng Ji'an nodded and said, "Yes."

Nan Guodong smiled and said: "Don't be too burdened, this is just a test, even if it fails, it's nothing, we can still find shortcomings from it and make corrections."

Ye Fei shook his head with a smile and said, "Even if it's a test, it's a test of our grades, we can't fail easily!"

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

"We belong to the national laboratory after all!"

"They can't be made to look down on national labs."

"I'd rather die standing than live sitting down."

"Even if it fails, let the opponent lose a piece of meat."

"Professor Ye is right." Cheng Ji'an said, "I don't want to be underestimated by others. This is my first job after returning to China. I don't want my grades to be too bad."

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

Of course, he doesn't pay attention to it just because he has encountered it too many times.

Coupled with getting older, the blood subsides.

But Ye Fei and Ye Fei are still young people. If young people don't have passion, are they still young people?

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

Nan Guodong said: "Half a month later"

Ye Fei thought for a while and said, "OK!"

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

Nan Guodong said: "Do you have any questions?"

"No more!" The two shook their heads.

"Then go away!"

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

Ye Fei looked at the team members under him and said, "Everyone, in this half month, we will connect the data with the other two teams, and we will test it with Ali's programmers in half a month."

"This test is to test our research for half a year."

"You don't need to be too nervous, this is just a small test, even if it fails, it's nothing."

Although Ye Fei wants to win, he wants to make his team members feel at ease so that they don't have to bear too much burden.

Hearing this, the subordinate team members felt much relieved.

Ali is one of the top Internet companies in Xiaguo. Many programmers in the company are the top programmers in the country, and some of them are also very strong in the international arena.

Facing the cyber attacks of these programmers, they still have a certain pressure.

In the next half month, the three teams 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 supercomputing host of the Information Resources Research Center is connected to the supercomputing of the National Supercomputing Changan Center, which is one of the top supercomputing in Xia Kingdom.

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

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

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

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

"Yeah!" Ye Fei nodded.

After more than an hour, everything was ready.

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

Everyone stood up from their seats and said, "Get ready."

Nan Guodong said: "Okay then, let's start."

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

"Row!"

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 a few red numbers.

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

The more red numbers, the more programs in the cracked circle.

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

Cheng Ji'an nodded with satisfaction in his heart: "Very well, I have only been breached a few times in my defense mechanism, and I am already very satisfied."

Nan Guodong was also very satisfied, and said: "This system is very good, and Ye Fei has contributed the most to it. The core part of the circle is the cryptographic algorithm, and the main formula of the cryptographic algorithm was deduced by Ye Fei."

"All research is also based on the main formula. Only when 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 started."

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

"This..." Nan Guodong was astonished: "Is it so weak? It took less than ten seconds, and he was repelled?"

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

Cheng Ji'an saw that the red numbers disappeared within half a minute, he was surprised and said: "This is too strong!"

The defense mechanism researched by his team was breached several times in less than a minute, while the attack mechanism of Ye Fei's team knocked back the incoming enemies in less than ten seconds.

I don't know if you don't compare, and you will be judged if you compare!

Hangcheng, Ali, in a main computer room of the supercomputing center!
Many programmers sit in front of their computers, typing away at the keyboard.

These programmers are all programmers from Ali Dharma Academy.

All the top programmers of Ali are concentrated in Dharma Academy, and this department is also very good, such as speech intelligence, language technology, machine vision, and decision-making intelligence, all developed by this department.

This department is managed by Mr. Yang, and 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're breaking in."

Manager Xu, who was walking among the programmers, said with a smile: "Very good, concentrate your firepower on the attack, and you must break through the opponent. Mr. Yang said, if you break through, give us a red envelope."

"Okay!" Everyone said enthusiastically.

Manager Xu saw that the battle was going well, so he walked out of the main computer room.

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

"Mr. Yang, we have already broken through." Manager Xu walked behind Mr. Yang and said, "Although it is difficult, it is still smooth."

"Yeah!" President Yang nodded: "But don't attack too fast, put a little water, after all, the opposite is an academician, and the other party just asked us to test, we can't make it too ugly, let The other party can't hold back."

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

"Manager Xu..." Suddenly, a person ran out from the main computer room and shouted, "It's not good, we were repelled."

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

The visitor said with a bitter face, "We also want to, but the opponent's attack mechanism is too strong. He was repelled as soon as he entered. After repelling, he entered again and was repelled again."

"We attacked more than a dozen times, and each time we were repelled in less than ten seconds."

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

Mr. Yang frowned, feeling astonished in his heart: "Is it so strong?"

You must know that these people are the group with the strongest offensive capabilities in Ali's computer technology.

Even in the international arena, these people are also skilled.

But now it has been repulsed by the opponent many times.

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

At this moment, the main computer room was full of rage. Everyone saw that they were repelled again, and almost smashed the keyboard in anger.

After looking at it for a while, Manager Xu said in surprise, "What kind of attack mechanism did the opponent use to be so strong?"

"No!" He shook his head and said, "Wouldn't the other side also organize 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 is impossible to organize a group of people to fight back against us."

"But this is too strong!" Manager Xu said: "The opponent is just a system, we are still alive, and we can't attack it."

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

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

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

"Even if it is an offensive mechanism, it cannot be so strong."

"If there is such a strong offensive mechanism, our company will win over it."

After speaking, he walked out of the main computer room, took out his phone and called Nan Guodong.

"Academician Nan, your system is quite strong!" Mr. Yang said with a wry smile, "Our programmers can't get in at all. I think this test will be over!"

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

"Where are you talking, you have also helped our company, and we should help you."

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

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

"Then I'm going to trouble Academician Nan."

"It's okay." Academician Nan said: "I can't explain clearly on the phone, I'll let him talk and video with you remotely!"

"Ok."
