my scientific age

Chapter 267 Cigarettes never leave your hands, scholars are standard.

There is no doubt that this set of encryption algorithms and password tables embodies the hard work of Hua Luogeng and Yu Hua, and their preciousness can hardly be measured by money.

This is the world's first mature asymmetric encryption algorithm!
When Tian Hong came to Tsinghua Park this time, he originally only wanted to get the help of Hua Luogeng to provide theoretical support for the asymmetric encryption algorithm prepared by the Blue Clothes Club.

Unexpectedly, Professor Hua and Yu Hua have already compiled the encryption algorithm and password table, and they are waiting for him to come.

It's like preparing a dish by yourself and asking the master for advice. The master said that you don't have to cook it, the dish has already been prepared for you, so just wait and eat.

The key is that the old master still doesn't charge the money.

Moving.

Inspiration from the depths of the heart.

Professor Hua Luogeng and Yu Hua's attitude towards their Blue Shirt Club is really different. Compared with other university professors, there is a world of difference.

"Doing our best for the country is the duty of Chinese scholars such as me. This is what we should do as Chinese scholars. This encryption algorithm and password table are related to the security of Chinese information. It is very important. Remember not to leak it to the Japanese. From the point of view of code breaking, even we can't decipher the secret telegram based on this encryption algorithm." Hua Luogeng took the conversation with a calm face, looked at Tian Hong, and exclaimed: "It must not be known by the Japanese! "

The importance of the encryption algorithm is self-evident. Hua Luogeng did not want the encryption algorithm to go to the hands of the Japanese as soon as it was given to the Blue Shirts.

If this happens, it will really be a disaster for the Chinese cryptography field.

However, for now, Hua Luogeng is very reassured about the confidentiality measures of the Blue Shirts.

After all, up to now, he and Yu Hua have not been assassinated by the Japanese for deciphering the red secret.

It can be seen from this that the security measures of the Blue Shirts Club are very good. Unlike other warlords, the interior is like a sieve, which is penetrated by the Japanese.

Yu Hua smiled and remained silent, quietly watching Tian Hong, who had been away for a long time.

This time, seeing Tian Hong, the leader of the Blue Clothes Club in Beiping, is very different from the last time I saw him.

Last time, there was a trace of awe and vigilance in his mentality.

This time, only my heart is left...

calm.

The heart is like still water, the wind is light and the clouds are light, and he no longer pays attention to Tian Hong's identity as the head of the Secret Service of the Blue Clothes Club.

The reason for such a change in mentality is that Yu Hua believes that he has mastered more knowledge and more wisdom.

"I remember, Professor Hua, classmate Yu, I won't disturb you. Thank you for this time. The Blue Clothes Club will remember it forever." Tian Hong nodded when he heard Hua Luogeng's words. Full of respect, he said goodbye.

"Goodbye, Team Leader Tian." Hua Luogeng smiled.

"Goodbye, Team Leader Tian." Yu Hua also smiled and nodded goodbye.

Tian Hong didn't waste time, and quickly left the house with the encryption algorithm and password table. Soon, the sound of the car engine starting came from outside the door. The sound gradually disappeared from near to far.

As the sound of the car disappeared, the house suddenly became quiet.

"Zi..." Suddenly, there was the sound of a match burning in the living room, and the orange flame slowly burned.

"Originally I was going to find him, but Tian Hong came directly to the door. That's fine, so I don't have to make a trip. How are the preparations these days?" Hua Luogeng lit a cigarette, flicked the match, and threw it into the trash can , took a deep breath, and exhaled a puff of white smoke comfortably.

Cigarettes are always in hand, and scholars are standard.

"There's nothing to prepare, just keep everything in mind." Yu Hua smiled.

"You kid, you have a good temper. Take advantage of this rare opportunity." Hua Luogeng couldn't help laughing when he saw Yu Hua's confident appearance.

Due to limited funds and inconvenient transportation, domestic academic speeches and academic conferences are held very rarely, and each time is a rare opportunity.

And this academic speech was held by Yu Hua of the National Tsinghua University Department of Computing for the purpose of establishing the theory of asymmetric cryptography.

"Students understand, Master, Professor Zhuang is still waiting for me in the laboratory, and I may have to leave first." Yu Hua was not impatient at Hua Luogeng's advice, which was Hua Luogeng's concern, smiled and nodded, then stood up. , say goodbye.

He was called over halfway through. Professor Zhuang, who joined the oxygen-blowing furnace research project, was still waiting for him to go back in the mechanical engineering laboratory.

Today is July [-]th, tomorrow is the Lugou Bridge Incident, and the time is extremely tight.

Hua Luogeng nodded and did not ask about the research projects carried out by Yu Hua and Zhuang Qianding: "Pay attention to safety. Various people have come to me these days, including Americans and British, and it is very likely that someone will come to you."

"Students understand." Yu Hua was thoughtful, knowing the reasons for these situations, but he was not flustered, nodded and saluted.

The words fell, turned and left.

These people with careful thoughts are not important, and Yu Hua will not waste precious time on these people.

At present, the research and development of air separation equipment is progressing rapidly, and there is no time to toss.

almost.

The birth of oxygen-blown furnace technology is getting faster and faster.

……

Tian Hong's Buick drove away from Tsinghua Park. In order to hide people's eyes and ears, there was nothing special about this car. It was ordinary and normal.

The whole car sped along the highway at a high speed of [-] kilometers per hour, and after ten minutes, it stopped steadily in front of a grocery store.

The door opened, Tian Hong got out of the car with the asymmetric password information, and went to the grocery store. The car behind him quickly drove away without stopping.

Enter the grocery store and come to a brightly lit room inside.

Standing in front of the door, Tian Hong slightly adjusted his collar and sleeves, then pushed the door open and entered.

In the room, a middle-aged man in a suit was sitting at the table. His face was Chinese, his eyes were bright and sharp, and his body was filled with an aura of not being angry and self-righteous. He was holding a newspaper and reading.

"Director." Tian Hong respectfully said.

The person in front of him was the top commander of the Secret Service and his superior, the director, Dai Li.

Dai Li, who already exuded the temperament of a boss, glanced at Tian Hong: "How is it?"

"Professor Hua and Yu Hua seem to have expected me to go. They have already written a set of encryption algorithms and password tables. After their subordinates arrived at Tsinghua Garden, they gave me the encryption algorithms and password tables." Tian Hong briefly described In this case, he immediately stepped forward and handed over the extremely precious encryption algorithm and password table to Dai Li.

Dai Li was stunned when he heard the words, he didn't expect this result.

Asking Hua Luogeng and Yu Hua for help and providing theoretical support is the decision of the Secret Service after discussion. I thought that Professor Hua Luogeng might not help anymore, but I would have thought that they had already compiled it.

Not only that, but also donate encryption algorithms and cipher tables.

Yes, this is an alternative donation.

Dai Li was very aware of the essence of Hua Luogeng and Yu Hua's actions, but it was precisely because he understood the essence of their actions that Dai Li was moved.

You know, this is the first mature encryption algorithm in the world, and it may be the academic achievement of Hua Luogeng and Yu Hua.

The importance of academic achievements to a scholar, even Dai Li, who is a layman, is very clear.

"They are the pillars of the party-state... Pheasant, the information about Professor Hua and Yu must be kept strictly confidential, and the Japanese must not know it, otherwise, their lives will be in danger." Dai Li took a deep breath and slowly said.

"Yes!"

Tian Hong nodded.

"Does Professor Hua know about the fact that the red secret materials cannot continue to decipher the contents of the Japanese army's communications?" Dai Li turned and asked Tian Hong.

With the entry into July, the red secret information in our possession was unable to decipher the content of the Japanese army's communications. After analysis, it was believed that the Japanese army had a high probability of upgrading and replacing the new password, rather than finding that the red password was deciphered.

It is a common practice for the military of various countries to upgrade and replace the password every six months or three months.

Tian Hong responded: "My subordinates have not informed Professor Hua for the time being."

"Don't disturb Professor Hua for the time being, the department is already organizing people to decipher it. If it doesn't work, I will trouble Professor Hua again." Dai Li made an arrangement.

Tian Hong nodded: "This subordinate understands."

……

Mechanical Engineering Lab, 9:18 PM.

The light in the laboratory office is bright, and the incandescent lamp hanging above is constantly releasing a dazzling yellow light, illuminating the two busy people below.

On the workbench, Yu Hua and Zhuang Qianding each stood in the middle, facing the design drawings below, with various drawing tools and discarded drawings on the right, and a plate of coarse grain steamed buns and cold sweet potato porridge on the left.

At this time, Zhuang Qianding, who was busy drawing preliminary sketches, threw away the pencil and signaled Yu Hua to calculate the data. Then, the big hand stained with ink stretched to the left and picked up a coarse grain steamed bun to start nibbling on.

When he caught the cold, he swallowed the steamed buns after chewing, and Zhuang Qianding looked at Yu Hua: "Have the data been calculated?"
