Institute of information engineering, Chinese Academy of Sciences.

Looking at the old man with grey hair coming towards him, academician Gao Junfa hurriedly greeted him and asked.

"Old Xue, have you made it clear? What's going on. "

A few days ago, the Ministry of industry and information technology suddenly said that the whole project of quantum encryption algorithm was suspended.

Almost all the people involved in the project were confused and didn't know exactly what happened.

As the academic leader of the whole project, and one of the most prestigious of them, academician Xue was naturally forced to retreat by a group of people as a representative to discuss with the science and Engineering Bureau.

These days, Gao Junfa has been trying to find out about his old friend, whether he has got this idea or not, but he has never met anyone.

Now it seems that this statement should be discussed.

But from the look on his face, it didn't seem optimistic.

Seeing academician Gao, who was in a hurry to come to him, academician Xue Jinhui subconsciously wanted to hide, but saw that there was no place to hide around. Besides, people had already called their names, so he had to helplessly watch him go to his own front, cough gently and open his mouth to explain.

"It's a complicated thing to say All in all, you just need to know that quantum cryptography has been solved. "

Solved it?

Hearing the unexpected news, academician Gao Junfa was stunned first, and his eyes immediately stared at the eldest. The expression on his face was no less than that when he first heard the news.

"Solved? How can it be! "

“…… At first, I was as surprised as you, "continued academician Xue Jinhui after a pause," but in fact, I have already confirmed this with my own eyes. "

Seeing the old friend's words don't seem to be deceiving, academician Gao Junfa said hurriedly: "have you seen that algorithm?"

Academician Xue Jinhui nodded his head.

"I've seen it."

"Tell me about it! What is the encryption algorithm like? Who made it? "

Some subtly moved away, academician Xue said with a slight cough.

"I can't tell you about these things for the time being. In short, you know that's OK."

Seeing the old friend refused to say, the academician was in a hurry and subconsciously played the emotion card.

"You can't believe me?"

"It's not a matter of faith, it's a matter of principle." Academician Xue sighed and continued, "don't worry, this algorithm must be developed for use Anyway, in about a month or two at most, we should be able to see the true face of this algorithm. "

Although academician Gao wanted to say something else, seeing academician Xue's expression that he didn't intend to give in, he finally gave up his mind.

At this time, he also realized that he was abrupt. This kind of thing is that he signed a confidentiality agreement, which is really not very inquisitive.

In fact, if he wasn't too curious, he wouldn't have opened the door.

With a long sigh, the senior academician shook his head.

"There are talented people coming out of the country That's all. I'll wait. "

After escaping from academician Gao, academician Xue did not dare to stop more on the road, for fear of being blocked by other old acquaintances to ask the same questions, and hurriedly returned to his office.

Let the Secretary to brew a cup of tea, drink two, originally intended to read the literature for a while, but he felt how can not sit, always feel like there are 10000 ants crawling in the heart.

Finally, he could not help but ask his secretary to book a high-speed rail ticket for himself, get on the train to Jinling, and come to Jinling University in the name of lectures.

Jinling University will not refuse his visit to this big bull in the field of cryptography in China. It will soon arrange all the troubles for him.

At the end of the lecture, academician Xue declined the invitation of the dean of the Information Engineering Institute to have a meal. Academician Xue walked around the campus of JINDA at will and went to the office building of several institutes. He asked for the way and found academician Lu's office door.

When he got to the office, there was no one in the office, only a little girl who was probably an assistant sitting not far from the door.

Looking out of the window, academician Xue knocked on the door and walked in. He asked in a friendly voice.

"Is academician Lu there, please?"

Stop the pen in his hand, Zhao Huan looks up at the strange old man, and feels strange. In recent days, there should be no appointment for a visit.

However, she did not encounter such a thing twice, so she said.

"Academician Lu is at Jinling Institute of higher learning these days. What can I do for you? I can call the professor and ask when he will come - "

seeing the little girl reach for the phone, academician Xue said quickly.

"You don't have to let him come here, is it? I'll go there myself. "After a strange look at the old man's back, Zhao Huan thought about it. Finally, she opened the computer to edit an email and sent it to the professor.

These days, the professors are basically at the higher research institute. It is said that they are busy with a national project. She had not inquired about what it was, and apparently the boat could not say it.

However, it must be very important.

……

Although he made an effort in Jinling University, academician Xue was not discouraged.

When I came to Jinling, I didn't see the inventor of the encryption algorithm. How could he not go back empty handed.

After arriving at Jinling Institute of higher learning and explaining his intention to the doorkeeper, academician Xue made a simple identity registration at the door and was soon released. A security guard took him to the direction of Semiconductor Institute.

Looking at the security guard walking in front of him, academician Xue couldn't help but guess in his heart that most of the academician Lu Yuan knew he was coming before he came here.

Finally came to the door of the laboratory, he hesitated for a moment, and finally reached out his right hand.

However, just as he was about to knock, the door opened with a squeak.

I saw a young man in a white coat and a little messy hair, with a handle in one hand, appear behind the door.

Although it was the first time to meet, as an academic, he recognized the face at the first time, but before he spoke, the man began to speak.

"You are academician Xue of the Institute of information engineering?"

"It's just me," academician Xue nodded his head and said with some prudence, "I'm sorry to disturb your research! But I'm really curious about that quantum encryption algorithm, so I came here without asking... "

"I won't disturb you, but I'm not sure if I'm one day ahead of time," Lu Zhou smiled and looked up and down curiously at the strange old man standing at the door. Then he stepped aside and made a sign to invite in Director Li told me about you. Come in and talk. "

"Director Li?" Without moving, academician Xue looked at Lu Zhou in surprise, "how does he know I will come here?"

"He didn't say you were coming, but after I heard about you, I guess you'll probably come here," explained Lu Zhou with a smile, "just as I have some questions to discuss with you Come with me. The experiment is just one step away. "
