Chapter 95 How many surprises are there?
"Today I finally saw what a true genius is. Professor Wang has never praised anyone like this before."

Evening self-study is over.

Cui Li led Xu Yuan to the doctoral student dormitory.

On the way, I recalled the scene when the project team was conducting research on the new collision method provided by Xu Yuan.

I am still very excited.

I couldn't calm down for a long time.

The more I understand Xu Yuan's new differential attack method, the more I can feel its advantages.

It's a shame why I didn't use this method from the beginning.

This resulted in such a long waste of time.

Otherwise, the MD5 password might have been cracked by now.

However, Professor Wang Xiaoyun also gave a positive judgment, saying that with the help of Xu Yuan's method, the MD5 password can definitely be cracked, letting the American Standards and Technology Bureau know one thing.

Their codes are not unbreakable.

Cui Li was deeply stimulated at first and was very envious of Xu Yuan.

But after listening carefully to Xu Yuan's explanation, I was quickly attracted by his amazing and unique way of thinking.

I finally understand why a genius is called a genius.

Although he is Xu Yuan's senior in terms of age and academic qualifications, he already admires him in his heart.

What's more, he is also a member of the MD5 project team. If the team can successfully crack MD5, which has left all experts in the entire cryptography field helpless, the academic achievements that can be achieved will be unimaginable.

In the future, it will be of great help whether you are participating in projects or evaluating professorial titles.

In a way.

This time, he also benefited from Xu Yuan's help.

His attitude was naturally extremely respectful and humble.

I care more about it than I do about professors in the college.

"I was able to come up with a new collision method thanks to Professor Wang for inviting me to participate in MD5 password cracking."

"Otherwise I probably wouldn't have touched hash functions."

In response to Cui Li's praise, Xu Yuan explained with a smile, still maintaining the humility of a junior.

And what he said was indeed correct. If Professor Wang Xiaoyun had not taken the initiative to come to Qinghua to invite him and left relevant information, he would have been drawn into the new field of cryptography.

He is probably just reviewing the math and physics courses he took as an undergraduate in mathematics.

Cui Li's bright smile grew even wider at this moment.

Although Xu Yuan is a genius and has just achieved something to be proud of, he does not seem to be complacent at all.

Immediately my favorable impression of him doubled.

He continued the topic: "It takes talent to learn hash functions. I am still not as good as you even though I have a PhD."

After saying that, he suddenly thought of something and added.

"By the way, junior brother, are you really leaving tomorrow? Otherwise, stay here for a few more days."

"It just so happens that I'll take you to appreciate our local customs and practices."

"There will be opportunities in the future." Xu Yuan declined politely.

"At present, Professor Wang and his team have adopted a new collision method. Once the MD5 cracking work is on track, my absence will not have any impact on the progress."

"Do not worry."

"It won't take long to successfully crack it."

Cui Li listened to Xu Yuan's answer word for word, and couldn't help but let his imagination run wild.

Imagine the scene when the team announced to the world that they had cracked the MD5 password.

He would not question what Xu Yuan said.

Just as he was thinking about it, he noticed that Xu Yuan suddenly stopped, and then he quickly came to his senses and raised his eyes.

"Brother, we are here."

After saying that, he took the initiative to open the dormitory door and walked in to introduce Xu Yuan.

The doctoral student dormitories at Qilu University are also single rooms, and the environment and layout are very good. This one in particular is clean and bright inside and is obviously carefully selected.

Xu Yuan was just staying here for one night as he had to go to Yanjing tomorrow.

There are no requirements for accommodation.

After separating from Cui Li, he simply packed up his things, washed up, and went straight to bed.

No more cracking of passwords.

In fact, there is nothing wrong with staying at Qilu University for the time being. Mainly because when he called several professors to wish them a happy New Year during the Spring Festival, Xu Chongxing said that Academician Song Wencong was attending a meeting at the headquarters of Yenching Aerospace Industry Group.

Apply to formally develop the latest generation of domestically produced stealth fighter jets.

I hope the project will be approved.

However, because several other aircraft design institutes have expressed different opinions, no final decision has been made yet.

He said that he might be asked to attend the discussion meeting at that time.

Determine the appearance layout of the stealth fighter.

In this situation, in order to help Academician Song Wencong promote the project as soon as possible, he must stay in the remote campus of Qinghua University so that he can go there at any time if there is any emergency.

No words were spoken all night.

The next day.

After breakfast, Xu Yuan took the car arranged by Professor Wang Xiaoyun to the station to buy tickets.

It is worth mentioning that Wang Xiaoyun and Ding Jian were unable to go to the station to see them off because they were impatient to use the new method to crack the MD5 password.

Just asked Cui Li to help with the luggage.

Xu Yuan naturally had no complaints about this. He was very happy to see professors like Wang Xiaoyun caring so much about it.

At the very least, this means that the progress of cracking the MD5 password algorithm will increase rapidly.

……

……

"Brother Yuan, you came a little late this time. If we wait for two more days, I'm afraid those animals will eat all the roast chicken."

On the Qinghua campus, Wang Haitao and others helped carry the luggage and complained about what had happened in the past two days as they hurried to the Bauhinia Apartment. Wang Haitao was very dissatisfied with the behavior of the other two.

After careful investigation, Xu Yuan found out that Wang Haitao had packed two roast chickens in his suitcase when he came back this time. They were specialties from their hometown.

As a result, because he went to Qilu University first and stayed there for a day, Li Zhenya and Liu Yang couldn't help but eat first.

At this time, Liu Zhenya, who was beside him, quickly replied: "We specially left one for you."

He also praised the specialties of Wang Haitao's hometown.

"Don't say that."

"The roast chicken Haitao brought tastes really good."

"It's much better than the Peking duck in Yanjing." Liu Yang nodded in agreement.

Xu Yuan naturally wouldn't get angry over a roast chicken. After listening to what they said, he put on a smile and said something along the lines.

"Then you must try it later."

Li Zhenya, Wang Haitao and Liu Yang did not ask Xu Yuan why he reported one day late.

Xu Yuan thought it was nothing special so he didn't bring it up.

However, just as they walked downstairs of the Bauhinia Apartment Building, they saw a familiar figure walking towards them quickly.

When they got closer, Li Zhenya and others immediately greeted them.

"Hello, counselor."

Although Xu Yuan didn't know whether Lu Chunming was okay, he still followed everyone outside and called out to the counselor.

Lu Chunming first looked at Li Zhenya and the others and nodded slightly, then he fixed his gaze on Xu Yuan.

"You're finally back to school. No wonder Professor Tang asked you to come here today."

A happy smile instantly appeared on his face.

"Professor Tang is looking for me?" Xu Yuan asked back, thinking of something.

"Professor Tang asked you to go to his place after you come back." Lu Chunming answered truthfully immediately: "But it's not urgent. Go back to the dormitory and pack your things first."

The voice just fell.

Li Zhenya's voice suddenly rang in my ears.

"Xu Yuan."

"Just follow the counselor and give us the things."

"The roommate is right. It saves you from having to make an extra trip." Liu Yang also expressed his support.

Xu Yuan thought for a moment and handed all the things to Li Zhenya and the others, and decided to go to Professor Tang first to take a look.

"Just help me put the things on the table, I'll be back soon."

After talking to his roommate, he turned to face Lu Chunming.

"Let's go then."

"I'll go with you."

Seeing this, Lu Chunming nodded to Xu Yuan, and then walked in front to lead the way.

As for Tang Shihong's office, both of them were very familiar with it, so they were not in a hurry on the way.

We talked about study while walking.

"You got full marks in all subjects in the sophomore exam this time. Even I can't help but envy you for your achievement."

"I guess you'll be able to graduate early soon, and truly become my junior."

Xu Yuan remained relatively calm as he listened to Lu Chunming's words. After all, the matter had been determined the moment he finished the test, and getting full marks in all subjects was completely normal.

"Then you'll have to rely on your senior brother to take care of you." He smiled and joked after Lu Chunming finished speaking.

Although Lu Chunming didn't say anything about this, he thought in his heart that he would probably have to rely on his junior brothers to take care of him.

Soon the two arrived at the door of Tang Shihong's office. As soon as they knocked on the door, a familiar voice came from inside.

"Please come in."

"Teacher, Junior Brother Xu Yuan is here." Lu Chunming was the first to speak and greet him.

Then he turned around and left to the graduate student discussion room on the same floor, leaving Xu Yuan and Tang Shihong to talk alone.

"Hurry up and sit down."

Tang Shihong raised his eyes and saw Xu Yuan and immediately became enthusiastic.

While inviting him to sit down on the chair next to him, he personally poured a glass of water and handed it to Xu Yuan.

Seeing this, Xu Yuan quickly stood up and took it with both hands.

Then, Tang Shihong started talking about business in a friendly tone.

"I received a call from Professor Wang last night and learned that you had gone to Qilu University."

"Tell me about it."

"What amazing thing have you done to make Professor Wang praise you so much?"

Xu Yuan listened to everything Tang Shihong said. He didn't expect Professor Wang Xiaoyun to bring up this matter so quickly.

But there was nothing to hide, so I just organized my words and started explaining.

"Nothing special. I just developed a more efficient collision method when trying to crack the MD5 password, and convinced Professor Wang and his team to give up their original cracking progress."

"Now they are using my collision method to crack it again, but the efficiency has increased significantly."

Tang Shihong, who originally had a smile on his face, froze instantly after hearing these words.

Then he was stunned for less than two seconds and then shouted excitedly.

"Isn't this special?"

"Professor Wang is willing to give up his previous research progress. It seems that the collision method you have developed is amazing."

"Don't tell me you've cracked the MD5 password later."

Xu Yuan then said innocently: "Not yet."

Tang Shihong finally breathed a sigh of relief after hearing this. He was really afraid that Xu Yuan would say that the password had been cracked, which would be too shocking.

Unfortunately, he hadn't completely relaxed yet, and heard Xu Yuan add a sentence right after that.

"But it shouldn't take long."

My emotions fluctuated greatly again, and I really couldn't guess how many more surprises Xu Yuan had.

　There are also nights.
