Chapter 102 International Cryptography Conference

Because Xu Yuan's exam was rather special, he was not in the same examination room as other candidates from the same department. Instead, he took a separate discussion room and was personally supervised by Tang Shihong.

Looking at the entire Academy of Mathematical Sciences, I am afraid you won’t find another exam model like this one.

Moreover, the entire test paper is composed of questions set by several professors in the department, so it is definitely more difficult than a normal graduation exam.

It was not yet eleven o'clock in the morning.

Xu Yuan, who was completely immersed in the exam, suddenly stood up and stretched.

Get out of deep learning mode.

Throw your pen on the table and raise your hand directly.

"Professor Tang."

"I have finished the test paper."

Tang Shihong was sitting next to him, busy with his work. When he heard Xu Yuan's voice, he raised his eyes and first looked at the time, then moved his gaze to Xu Yuan with a look of surprise.

“It’s much faster than I expected.”

As he said that, he stood up, walked to Xu Yuan, picked up the test paper, and started correcting it on the spot.

At the same time, he did not forget to talk to Xu Yuan.

"This test paper is quite difficult."

"Several professors in the department knew that they were giving you the questions, so they spent a lot of time and effort on them."

“Even if we ask senior students to do it, it’s probably not going to be easy for them to pass.”

Xu Yuan took over the conversation and replied: "I already felt it when I was doing the test just now."

"Many of the questions are classic, and some are even deliberately set up to mislead you so that you can easily get into the wrong train of thought. There were two questions that took me quite a while."

He was absolutely right.

In order to ensure that his style was carried out as far as possible, he paid special attention to the progress of the panel when answering the questions.

So he was very confident about his test paper and was sure to get full marks.

And that's exactly what happened.

It didn't take long for Tang Shihong to correct the entire test paper very efficiently.

Even though he knew Xu Yuan's strength and talent very well, he still felt excited when facing this test paper.

"Although I know these questions are not difficult for you, it is still terrifying to be able to finish them in such a short time and get full marks."

"Especially the steps you used to answer each question are even more standard than the standard answers."

“It’s hard to find a single wrong place.”

After listening carefully to Tang Shihong's words, Xu Yuan felt relaxed and smiled as he uttered three words.

"That's good."

"You've passed. Remember to pay more attention to your graduation thesis after school starts." Tang Shihong put away the test paper and waved his hand, not forgetting to remind him.

After successfully finishing the last exam of his undergraduate studies, Xu Yuan naturally did not stay here for long. He said goodbye to Tang Shihong and immediately packed up his things and left.

Because he only needed to take this one subject, he had to leave school much earlier than Li Zhenya and Wang Haitao.

So at noon, everyone met up to have lunch outside the school, and Chen Yuran and her roommates also came along.

The main reason is that the people in their two dormitories have seen each other quite often in recent days, so they are quite familiar with each other.

Since we are all going to leave school for summer vacation, we might as well have a meal while we're there.

-

"I really envy Xu Yuan, he can go home directly after dinner."

Li Zhenya took the initiative to bring up the topic at the lunch table, and this sentence immediately resonated with everyone.

Especially when she thought about the exams she had in the next few days, she felt even more jealous towards Xu Yuan.

"Geniuses have privileges wherever they are, so ordinary people like us should just take the exam."

"From now on, Xu Yuan will be our senior." Li Zhenya agreed with Yu Ruilan's words.

To this, Xu Yuan interrupted and said, "Just keep calling me by my name."

As for Chen Yuran, who was sitting next to him, she had no intention of joining the conversation. She turned her head and looked at Xu Yuan seriously and said, "Then I'll go to the station to see you off this afternoon."

"No, I don't have much stuff." Xu Yuan replied lovingly, "Don't delay your exam."

"Okay then." Chen Yuran obeyed obediently.

Xue Mengjie happened to be sitting opposite Xu Yuan and the others, and watched helplessly as she was fed dog food.

Then he quickly changed the subject to interrupt their conversation.

"What are your plans for summer vacation?"

After the new question was raised, it aroused everyone's interest. After a little thought, they began to talk about their plans.

"I can buy a computer in my sophomore year. I plan to help with my family's small business to save some money."

"Probably stay home."

Compared to Li Zhenya and Wang Haitao who spoke first, Liu Yang answered seriously: "My home is in Yanjing. I guess I will come to the school library often to read and review during the summer vacation." After saying that, he glanced at the seat where Xu Yuan was sitting.

Yu Ruilan couldn't help but praise him when she heard this: "I didn't expect that Xu Yuan is not the only one in your dormitory who likes to study."

Xue Mengjie saw that everyone was talking but Xu Yuan was the only one who didn't move, so she just went close to his face and fired at him.

"Xu Yuan, do you have any special plans for summer vacation?"

After saying that, he did not forget to look at Chen Yu Ran and added, "Will he come to find our Yu Ran secretly?" Although Chen Yu Ran did not say anything after hearing this, she was looking forward to Xu Yuan's answer in her heart.

Xu Yuan knew that although Chen Yuran's hometown was far away, she and her family were currently living in Yanjing, so it was relatively convenient and hassle-free if she wanted to find her. However, thinking of his schedule next month, he had to put down his chopsticks temporarily and briefly explained the matter.

"Of course I will go visit Yu Ran when I have time, but next month I have to attend an international conference in the field of cryptography."

As soon as these words came out.

Everyone stopped what they were doing and raised their eyes.

"In the field of cryptography?"

"International conference?"

A question mark slowly emerged in my mind.

They knew that Xu Yuan studied both mathematics and engineering mechanics, but where did this cryptography come from?

Even my roommate Li Zhenya asked curiously, "Why did you invite you to participate in the international conference on cryptography?"

"Tell me about Brother Yuan." Wang Haitao also became interested.

Because Xu Yuan usually cooperates with Wang Xiaoyun's team to crack MD5 passwords in the discussion room.

In addition, the complexity of the hash function made it difficult for several people in the dormitory to understand it, so they naturally did not take the initiative to ask any questions.

I don't know if the situation here is normal.

Since this matter has been mentioned today, there is no need to keep it a secret.

Xu Yuan organized his words a bit and then began to explain to everyone.

"I was invited by Qilu University to participate in a cryptographic algorithm cracking project. Now that the project has produced results, it will be announced at this year's International Cryptography Conference."

"As a member of the project, I will also go with you."

After listening to Xu Yuan's explanation, everyone suddenly felt like they didn't know what to say.

No matter how you look at it, it seems that Xu Yuan is pretending again.

Forget about any international conference, they don’t even know the relevant knowledge of cryptography.

Xue Mengjie was especially regretful. If she had known earlier, she would not have asked that question specifically.

There was a silence of more than ten seconds before Chen Yuran's voice was heard: "Will we see you on the news then?" She was looking forward to Xu Yuan's participation in the international conference.

As a top conference in the field of cryptography, overseas parties will certainly provide various reports at that time.

But it is uncertain how popular it will be in China.

After all, there are too few people willing to pay attention to cryptography nowadays, and continuous efforts are needed.

The thought stayed here, he thought about it and gave an uncertain answer.

“There should be reports.”

"Then I'll sit in front of the computer and cheer you on that day." Chen Yuran made a cheering gesture with a serious expression.

This simple dinner ended at around one o'clock. After Xu Yuan and Chen Yuran separated, they returned to the dormitory to pick up their luggage and went straight to Yanjing Station to prepare to go to Luyang.

My house in the provincial capital is currently being renovated, so I can go back and review the plan before the conference starts.

In addition, he does not plan to return to his hometown this summer vacation. In addition to the fact that his parents and sister are in the provincial capital, the main reason is that things are not very convenient in the countryside and there are not many young people at home right now.

It is worth mentioning that this time Xu Yuan called home in advance.

So as soon as I came out of the station, I saw my father Xu Jianguo.

"Did you eat on the way?"

When Xu Jianguo saw his son, he hurried over to ask about his well-being. When he took the luggage, he saw a rectangular package and asked curiously.

"Is this the Olympic torch that carries the Olympic flame?"

"My mother has been talking about it for a long time." Xu Yuan nodded and replied with a smile.

Ever since the footage of him participating in the Olympic torch relay was reported in the news that day, Ms. Liang Yanli called to inquire about it after seeing it. He casually said that he would be remembered when he brought the torch back.

I simply brought it back with me during this summer vacation so that it wouldn’t gather dust in the dormitory closet.

After returning home and taking out the torch, Ms. Liang Yanli was naturally very happy with it.

He said he wanted to customize a glass cabinet at home to store them properly, and he was reluctant to put it in the store.

In addition, his sister Xu Ying also successfully ended her sophomore semester and officially went on vacation two days after he arrived home.

Originally, Xu Ying planned to find a part-time job during the summer vacation, but Xu Jianguo was worried and asked her to help out in the store. After all, the family only had to support one college student and did not need to worry about money.

Time always passes fastest during the holidays. Xu Yuan originally wanted to research the direction of his graduation thesis, but ultimately could not decide on the appropriate content.

I had to put this matter aside for the time being and study it seriously after attending the international cryptography conference.

In the blink of an eye it is August.

Considering that his parents and sister didn't know much about cryptography, he didn't explain it in too much detail, only saying that he was going to attend an academic exchange meeting.

After completing the relevant formalities with Professor Wang Xiaoyun, we officially set off two days before the meeting.

In addition to Wang Xiaoyun and him, the team also included Professors Ding Jian and Wang Changxin, as well as Cui Li, who is also a member of the project.

The five of them met at Yanjing Airport on time and then flew to Santa Barbara, California, America.

According to data released by relevant agencies, the conference will be attended by 300 experts in the field of cryptography from all over the world, including Professor Biham, the world's top cryptographer, and official personnel from the Bureau of Standards and Technology.

It is easy to imagine what kind of earthquake it would cause in the field of cryptography when the news that the MD5 password was cracked was announced.
