Information Resources Research Center of Chang'an University of Electronic Science and Technology, in the office!

Ye Fei and Cheng Ji'an sat here, and the two wanted to discuss the division of labor.

Cheng Ji'an said: "I heard that you advocate using SM2 and SM4 to study cryptographic algorithms, right?" ”

"Yes!" Ye Fei said: "If you have any good ideas, you can mention them." ”

Cheng Ji'an said: "I don't have any good ideas, with the proposal of SM2 and SM4, I think it's not bad." ”

"I heard Academician Nan Guodong say that you proposed such a very traditional research method based on the current national situation at that time, and I very much agree with this."

"But one thing is wrong, tradition does not mean that it is not new."

"You can play something new with something traditional."

"For example, adding the cloud in SM2 and SM4."

"Cloud?" Ye Fei was stunned and said: "Join cloud computing? ”

"Yes." Cheng Ji'an said: "If cloud computing is added to the encryption algorithm, it can not only greatly accelerate the computing speed of the encryption algorithm, but also improve the security of the private key based on the SM2 collaborative signature algorithm. ”

"I know you want to introduce the idea of a white box in SM4."

"It's a great idea, but there's one thing we can add that makes cryptographic algorithms better."

Ye Fei raised his eyebrows and asked, "What is it?" ”

After all, he is not a professional in cryptography, so he is not as professional as Cheng Ji'an.

"Quantum algorithms!"

"If you add a quantum algorithm, you can correct errors with quantum, and then add a white box."

"With them, SM4 can have the ability to attack exhaustively, and quantum resources are the resource backup of SM4."

"This will improve SM4's weak point and attack ability!"

"At this point, connect SM2 and SM4 together."

"At this time, the cryptographic algorithm can be realized, with functions such as accelerated computing speed, high defensive security and strong attack ability."

Ye Fei's eyes lit up: "If that's the case, this cryptographic algorithm is too perfect." ”

Come to think of it, the defense capabilities of SM2 and SM4 were originally very strong, but now coupled with the fast running speed and strong attack ability, this is equivalent to a hexagonal warrior, and none of them is a short board.

Cheng Ji'an said: "I heard that you also proposed Trusted Computing 3.0 at the conference? ”

"Hmm!" Ye Feidao: "This is also what I discovered when I was studying number theory, if our country can develop credible computing 3.0, then in the field of cryptography, to achieve corner overtaking." ”

Trusted computing is very important, and the most important point is the private key, which is an integral part of chip manufacturing.

If there is no private key in the chip, then sensitive data sent to the chip cannot be authenticated and encrypted.

It is equivalent to saying that if there is no private key in the chip, the chip will be wasted.

Therefore, any country that masters the most advanced trusted computing will master some of the core technologies of chip manufacturing.

Xia Guo is not capable of producing low-nanometer chips now, but if he masters Trusted Computing 3.0, then he can grasp part of the initiative in the chip field.

Foreign countries have chips, and Xia has trusted computing and rare earths.

Rare earths are one of the materials used to make high-end chips, and Xia is the country with the most rare earths, accounting for 71.1% of the world's total rare earth ownership.

Ye Fei said: "Of course, I was also joking at the time, as for how to study it, I don't have an eyebrow yet, I just put forward this concept." ”

"Hmm!" Cheng Ji'an nodded and said: "Regarding Trusted Computing 3.0, in fact, a few years ago, my teacher also said, he said that the era of Trusted Computing 3.0 will come within ten years. ”

"Many countries are also working on Trusted Computing 3.0, which is also a hot research in the field of computing, but it is only in the theoretical and conceptual stage, and there is still a long way to go."

Ye Fei asked, "Your teacher said, how can you study it?" ”

"We need to start with the Internet of Things and blockchain, and maybe after these two technologies are realized, Trusted Computing 3.0 can be born."

"Hmm!" Ye Fei nodded.

Cheng Ji'an smiled: "It's far away, let's continue to talk about cryptographic algorithms!" ”

After that, the two exchanged ideas for more than two hours.

Finally, the two will divide the task equally.

SM2 cloud computing is an area that Cheng Ji'an is good at, so Cheng Ji'an is in charge.

SM4 quantum computing is Ye Fei's field of expertise, so Ye Fei is in charge.

Each of them led 80 people to conduct research.

In the afternoon, Ye Fei settled in the research room of the theoretical group.

The Information Resources Research Center is composed of several research laboratories, and the research of cryptographic algorithms occupies several of them.

In the conference room!

Ye Fei sat on the first place and looked at the researchers under him.

These fellows are all top talents from major universities and research institutes across the country.

There are full and associate professors at 985 University, as well as researchers from the National Research Center.

Each of them, individually, is a top scholar in the country and an internationally renowned scholar.

And now, they are all led by Ye Fei.

At this time, Ye Fei felt a little proud and proud in his heart.

Of course, he is not a fledgling kid now, and he will soon suppress this emotion.

Ye Fei said: "In the next period of time, I will lead you to do some theoretical experiments. ”

"I hope that everyone will cooperate sincerely and strive to complete the experiment as soon as possible."

"Papapa......" everyone applauded enthusiastically.

Although they were not assigned to Academician Nan Guodong and Professor Cheng Ji'an, they felt a little lost in their hearts.

But it's okay to be assigned to Ye Fei's subordinates, after all, Ye Fei also has real materials.

Yue Fei in the crowd was bitter in his heart, he and Ye Fei were really destined, and he was assigned to a room, and he was also assigned to a group, led by Ye Fei.

Yue Fei said: "Is it because of my name that I am too close to Ye Fei." ”

"It must be so, ......"

Ye Fei said: "Let me talk about our next work. ”

"After my discussion with Professor Cheng, we still take the route of SM2 and SM4, with cloud computing added to SM2 and quantum computing added to SM4, and we are studying SM4 quantum computing."

"In this, the number of qubits, the number of general quantum logic gates, the depth of the quantum circuit, and the value of the quantum circuit are used as statistical parameters."

"Firstly, the quantum optimization of the SM4 algorithm S-box is ......"

Ye Fei spoke for more than an hour and explained the general experimental procedures.

Finally, he said: "Combined with the Grover algorithm to exhaustively attack the quantum circuit of SM4, the quantum resources required for the attack are constructed." ”

"There are three main parts to the research process."

"They are the preparatory knowledge, the quantum implementation of the SM4 algorithm subcomponent, the quantum implementation of the SM4 algorithm and the quantum exhaustive attack of the SM4 algorithm."

"Let's take these four parts step by step, first of all, the preparatory knowledge, which is the foundation of the foundation, only when the preparatory knowledge is ready, the rest of the work can be done."

Pre-knowledge is equivalent to the theory within the theory of all work.

"The research steps of the preliminary knowledge are the Grover algorithm, the SM4 arithmetic function, the key expansion algorithm and the classical implementation of the SM4 algorithm S-box."

"It's five steps, and we've got eighty people here, and we're going to divide it into five teams, and each group has sixteen people."

"I don't know you either, so I'll assign you randomly!"

Soon, Ye Fei assigned everyone.

Ye Fei said: "The meeting is dismissed, and the work will start tomorrow." ”

The next day, after breakfast, everyone went into the lab and got to work.

Time has passed quietly, and there are a few more days to enter 2026, and Ye Fei is almost twenty-five years old.

Along the way, Ye Fei felt very fulfilled.

Someone else is still looking for a job or going to school at the age of twenty-five.

At the age of twenty-five, he has already led a team of top domestic scholars to do experiments.

On this day, Ye Fei entered the room of the first group, and the five teams under him occupied a room each.

He walked up to a whiteboard and said, "Guys, come here." ”

Everyone stopped their movements, stood up and gathered around Ye Fei, and someone asked, "Team leader, is there something wrong?" ”

Ye Fei said: "Regarding the Grover algorithm, I will give you the main formula now. ”

"Master formula?" The crowd was amazed.

Someone asked, "Team leader, have you deduced the main formula?" ”

The main formula was the most important part of the experiment, and they had been trying to derive it all this time.

It's just that the main formula is the hardest part of the experiment, and they have only found a little bit of an eyebrow for so long.

"Hmm!" Ye Fei said: "It has been deduced, I will write it to you." ”

Ye Fei led his team members to do experiments, and they all liked to derive the main formula and hand it over to his researchers.

In this way, their research will also be much faster.

"Really?" Everyone looked at Ye Fei in surprise.

They couldn't believe it, usually Ye Fei stayed with them, and they also commuted to and from work together, and they didn't see Ye Fei working overtime.

The work they do seems to be similar to theirs.

But now Ye Fei actually told them that he had deduced the main formula.

It's also unbelievable.

Ye Fei said: "You are optimistic. ”

With that, he took out his pen and wrote the main formula on the whiteboard.

[Grover's algorithm takes |0>|1> as the output to prepare a uniform superposition state ......】

【G=(2|ψ><ψ|I)Uf……】

Ye Fei said: "This is the main formula, and you will rely on this main formula for research next." ”

They looked at each other, their eyes full of suspicion.

Although Ye Fei wrote out the main formula, they still couldn't believe it.

After all, so many of them didn't deduce the main formula, Ye Fei was just one person, and it took only a month to deduce it?

How is this possible?

Someone asked, "Team leader, is this the main formula correct?" ”

Ye Fei glanced at the other party and said, "You can check it and know if it's right." ”

He knew it was surprising, but he had absorbed everyone's inspiration to come up with the main formula in such a short period of time.

After that, the people carried out the calculations.

After Ye Fei saw it, he went to the other four groups and wrote the main formula to them.

They naturally didn't believe it, Ye Fei asked them to check it to know if it was correct.

Three days later, everyone was shocked.

The main formula is correct.

Someone was surprised: "How did the team leader deduce the main formula in such a short time?" Could it be that he was working on cryptographic algorithms before? ”

"But that's not logical!"

"The study of cryptographic algorithms, all of us only learned about it more than a month ago."

"It's impossible for the team leader to know in advance!"

Everyone nodded, it was true, it was impossible for Ye Fei to know in advance.

But if you don't know it in advance, then the main formula is deduced within this month.

But how is it possible to derive the main formula in a month?

Everyone was puzzled!

"I've heard that the team leader has deduced the main formula for the other groups."

"It took him a month to deduce five main formulas, is he dreaming of the main formula?"

Someone said: "Maybe it's a dream!" ”

Another person said: "Why don't we ask the team leader how he deduced the five main formulas in a month?" ”

"Hmm!" Everyone nodded, "Go and ask." ”

After that, everyone found Ye Fei and asked him how he deduced the five main formulas in a month.

Ye Fei said with a smile: "Actually, it is very simple to deduce the main formula in a short period of time. ”

Everyone looked at Ye Fei with bright eyes, expecting him to come up with a useful method.

Ye Fei smiled: "Read more, think more, and read more literature." ”

There is no way, I just absorb everyone's inspiration and brainstorm ideas, so that I can deduce it in a short time.

To put it bluntly, it's open.

When they heard this, the light in their eyes was extinguished.

Who doesn't understand this truth, we do it every day!

But I didn't do it either, and I deduced five main formulas in a month!

Lab next door!

"What?" Cheng Ji'an looked at the researcher beside him in surprise and said, "Ye Fei deduced five main formulas in a month? Really? ”

"Of course it's true." The researcher said, "I didn't believe this news at first, but after inquiring, it was. ”

"How did he do it?" Cheng Ji'an said in shock.

It's also awesome, he's never seen anyone come up with five master formulas in a month.

Even he, who has always been called a genius, can't do it.

Even when he was studying in Beiliguo, he had come into contact with many people in the academic upper circles, and he had never heard of such a thing.

It's not scientific, it's metaphysics.

"I don't know!" The researcher shook his head blankly and said, "The researchers under Professor Ye were also very puzzled, and they went to ask Professor Ye specifically, but Professor Ye didn't say anything. ”

"Is the master formula he deduced correct?"

"That's right."

Cheng Ji'an took a deep breath, suppressed the shock in his heart, and said, "I know." ”

He felt that it was necessary for him to talk to Ye Fei.

The next day, the office!

Ye Fei, Cheng Ji'an and Nan Guodong sat together.

Nan Guodong also knew about this, so the three of them sat together and wanted to talk about it.

Nan Guodong said: "I heard that you helped your researchers deduce five main formulas within a month, how did you do it?" ”

"Don't prevaricate me with words that read more and think more."

Ye Fei shook his head and smiled bitterly: "Academician Nan, I really can't help it, it all took me a month to deduce it with great effort." ”

"You don't want to say it, do you?" Cheng Ji'an.

Ye Fei said: "If I had a way, I would have said it a long time ago, so why lie to you." ”

"You don't want to know, is there really a way to quickly derive mathematical formulas?"

"If there were, math wouldn't be so hard."

After hearing this, Nan Guodong and the two nodded secretly in their hearts.

It is true that there are no shortcuts in the world of science.

"Really?" Cheng Ji'an said unwillingly.

Ye Fei shook his head and said, "Really not!" ”

"Okay!" Cheng Ji'an said helplessly.

Ye Fei smiled: "How is your group's research?" ”

Cheng Ji'an smiled bitterly: "We haven't even deduced one-tenth of the main formula, you help your group derive the main formula, and when your group's research is completed, maybe our group hasn't even finished researching one-third." ”

"So, your group is going to wait for our group."

Ye Fei smiled: "Of course it's okay, but do you need help in your group?" ”

Cheng Ji'an asked in surprise, "What help?" ”

Ye Fei said: "I can help your group derive the main formula." ”

Cheng Ji'an's eyes lit up, and he said expectantly: "Is it okay?" ”

"Absolutely!" Ye Fei smiled: "This is not a difficult thing for me. ”

Cheng Ji'an nodded and said, "Okay, please." ”

Ye Fei shook his head and said: "It's okay, they are all colleagues, I'm not doing you a favor, it's to reduce the burden on the country, develop the cryptographic algorithm as soon as possible, and help the country as soon as possible." ”

"Good!" Nan Guodong said excitedly: "That's a good point. ”

So, a month later, Ye Fei helped the people in Cheng Ji'an's group deduce the main formula.

And the time quietly came to the Spring Festival, and Ye Fei made arrangements for his next schedule.

He needs to leave the Information Resources Research Center for a while and return to Zhonghu University.

Because the laser experiment in the laser laboratory of Zhonghu University is in the final stage, he needs to go back and have a look.
