Chapter 234 Asymmetric Cryptography Achievements!
Inside the library.

"Yuping, Yuping, look, this is the barefoot doctor's manual I just bought, another book by Mr. Zhang San, the genuine edition published by Xinhua News Agency. I finally got it. Here it is." A young and energetic man The boy ran into the public reading room and came to a girl, panting a little, and then put the brand-new book he just bought in front of the girl.

"Thank you, Hae Sung, this book is very useful to me."

The girl with a gentle temperament was startled when she saw the barefoot doctor's manual on the table, with surprise in her eyes, and then thanked the boy: "Next week is my birthday, do you have time, if so, we will Let's go to dinner together."

"Yes, yes, of course." The boy nodded again and again and smiled.

"Thank you." The girl smiled.

"Brother Ziqian, hahaha, look what this is? I finally bought it!" Immediately afterwards, another boy ran in. He was so excited that he forgot the discipline of keeping quiet in the library, and came to a man who was At the desk of the self-study boy, he said excitedly.

"Ah! Why can't I buy it? My old man keeps urging me, dear brother, how about selling it to me for ten yuan?"

"Brother Ziqian, talking about money hurts feelings, I can borrow you to transcribe it, but I won't buy the book. This is the first batch of manuscripts published by Xinhua News Agency. It has both collection value and extremely high practical value."

"The full text of this book is 260 million words, how to transcribe it..."

"Brother Ziqian, I advise you to buy a copy as soon as possible. The value of this book is really too high, and, with the size of Xinhua News Agency, it is not enough to print enough supply to meet market demand. In a short period of time, I will I think it is the limit to have [-] copies printed. Now the situation in Peiping is tense, and the Japanese will come in suddenly tomorrow, and you will not be able to buy books at all."

"Does this book mean that you can buy it if you buy it? It's not a pirated copy from a roadside stall in front of the school in middle school. That's all, I won't learn it today, I'll try my luck."

"Brother, I'm sorry, what kind of book is your barefoot doctor's manual?"

"This is a medical book written by Mr. Zhang San. It records a lot of disease diagnosis and treatment methods, as well as various prescriptions and medicines. With this book, you can treat a cold and fever yourself."

"What, isn't this the same as the Compendium of Materia Medica?"

"There is still a difference, Compendium of Materia Medica..."

The original quiet atmosphere in the public reading room completely dissipated, and the relevant information about the Barefoot Doctor's Manual was circulated among the student groups, and there were many discussions and lively.

"It turns out that it has been published and sold. It's good." In the corner of the reading room, Yu Hua put down the pen and withdrew from the highly focused study state. , a smile appeared on the corner of his mouth.

Sure enough, Xinhua did not let him down.

As originally thought, whether other newspapers and bookstores can print the abridged version of the barefoot doctor's manual is uncertain, but Yu Hua is sure that the Xinhua News Agency, which is backed by the organization, will print the barefoot doctor's manual at his request.

It is hoped that this medical classic can spread throughout China and play its due role.

Compared with the era when the barefoot doctor's manual was published in the previous life, in today's all-out war of resistance, this book that condenses the essence of medicine is more needed.

It is Yu Hua's expectation that compatriots and front-line soldiers can die less.

After thinking about it, Yu Hua forgot about the barefoot doctor's manual, stopped paying attention, and turned his eyes to the notebook on the desktop.

It has been about a month and a half since the Yu's Seven Pagodas Project began. Now, Yu Hua, who has been studying analytic number theory and discrete logarithm problems for a long time, has finally completed his first goal after entering Tsinghua University.

Asymmetric cryptography theory results!
Inside the notebook is the core cornerstone of the theoretical achievements of asymmetric cryptography - the encryption algorithm and algorithm password table of the private key!

This is a major breakthrough in contemporary classical cryptography. Compared with the Enigma machine, which was adopted by the German army as the pinnacle of classical cryptography, the asymmetric cryptography that has changed from the basic level is ten times more secure.

Convenient, fast, with high timeliness and high security.

This is all the characteristics of the first-generation encryption algorithm of the asymmetric cryptosystem. At present, it is impossible for any country in the world to use any attack method to decipher the defense layer constructed by the first-generation encryption algorithm.

"From now on, I'm also a cryptographic expert."

Yu Hua glanced at the results of his hard work on the notebook, smiled slightly, and stretched out comfortably: "I'll get the first draft of the paper, after this paper is published, perhaps the British decipher the German Enigma in history. The combination of asymmetric cipher + Enigma machine, even if I want to decipher the cipher of this encryption mechanism, it will take more than a year and a half."

I have to say that Yu Hua is extremely satisfied with his work.

As the most practical cryptographic machine in modern times, the Enigma machine adopts a dynamic form of symmetric cryptography, and its cryptographic security is completely at the peak level of the symmetric cryptography era.

This is the world's most advanced information encryption machine. In theory, the Enigma machine's password has [-] billion possibilities, and it is almost impossible to decipher by brute force attack method. The super secret plan executed by the British in history can be deciphered. The German Enigma machine has quite a lot of luck in it.

However, times are different now.

The entire world will embrace the age of asymmetric cryptography decades ahead of schedule.

Based on asymmetric cryptography, combined with the best Enigma machine, there is an unprecedented guarantee of cryptographic security.

Without further delay, Yu Hua took out a piece of manuscript paper from his schoolbag, picked up a pen in his right hand, typed some ink, and began to write a paper on the theory of asymmetric cryptography.

The title of the paper is "Influence and Effect of Asymmetric Cryptography on Cryptography". Yu Hua explained the basic concepts of asymmetric cryptography system clearly, and then recounted the relationship and role between public key and private key, and the improvement coefficient of cryptographic security. Carefully compare the advantages and disadvantages of current symmetric ciphers and asymmetric ciphers.

The security is improved by orders of magnitude, with high timeliness, and asymmetric passwords crush symmetric passwords in almost all directions.

Of course, Yu Hua did not stupidly add the first set of encryption algorithm and algorithm password table.

The first set of encryption algorithm architecture is a core secret and cannot be exposed, but the discrete logarithm as the basic architecture is no problem.

There is no need to cover up this kind of directional content, because mathematicians from all over the world are not fools. As long as they glance at the results, they can immediately give the mathematical theory that is most suitable for asymmetric cryptography.

The algorithm password table has two systems of Chinese dialect and Beiping Mandarin, both of which are important core secrets. In a popular sense, this thing is a serious password table. If it is leaked...

No big deal either.

It's just that this algorithm and password table made by Yu Hua is invalid. Several days of hard work have been in vain and need to be re-created.

But Yu Hua didn't have the spare time to toss, and it was the last word to quickly publish the results and attack the next stage.

The whole paper is written very fast, what should be written and what should not be written. Today's Yu Hua can be described as a clear door.

The reading room gradually quieted down. After more than two hours, the [-]-word heavyweight achievements in the field of cryptography were freshly released. As usual, they re-examined and confirmed that they were correct. Yu Hua quickly put the papers and notebooks in the school bag and got up and left.

Go downstairs and go straight to the west courtyard.
