The asymmetric encryption system improves the security of passwords almost unprecedentedly. No matter what mathematical principle is used as the underlying core, its security is an order of magnitude improvement compared to symmetric encryption.
In short, the security of the first generation asymmetric encryption algorithm was ten times that of the peak of symmetric encryption.
As the Japanese entered the era of asymmetric cryptography,
You can imagine how difficult it is to break through the other party's password system.
This is truly a double-edged sword.
If used well, it will be beneficial to one's side; if used improperly, it will cause an extremely serious blow to one's own side.
"The students have thought about it, but they are still ready to announce it. This is a big move, deliberately letting the Japanese,
Or the whole world will enter the era of asymmetric encryption." Yu Hua nodded seriously and said.
Hua Luogeng was a little confused: "Big chess?"
"Asymmetric cryptography logically,
The decryption key cannot be derived from the known encryption key, but in practice, due to different underlying mathematical principles, it can still be cracked through comprehensive methods such as mathematical proficiency, brute force attacks, and cryptanalysis. I personally have something that others do not have
The unique advantage – super computing power.”
Yu Hua nodded, his eyes flickered, and he said seriously: "When Japan and other countries around the world enter the era of asymmetric cryptography, and when they establish the ultra-high security confidence based on asymmetric cryptography, I will use my super strong
With computing power, he has become one of the few, or even the only, people in the world who can crack asymmetric cryptography, thereby establishing an advantage in the information field for China and seizing information opportunities."
Information first!
This is the ultimate goal of launching asymmetric ciphers.
Is asymmetric cryptography highly secure?
Of course it’s high!
The RSA encryption algorithm based on this mechanism is still one of the most secure cryptographic algorithms in China in later generations.
The RSA algorithm length of 1024 bits is almost safe, and the RSA algorithm length of 2048 bits is extremely safe.
But in this era without computers,
Considering the timeliness of information transmission,
It is basically impossible to use large prime number decomposition for asymmetric cryptographic algorithms.
This gave Yu Hua, who had super computing power, an opportunity to take advantage of.
Once countries accept asymmetric cryptography and fully transition to the era of this achievement, then a personal show belonging to Yu Hua will come.
Because Yu Hua is currently the only human being in the world whose brain computing power is comparable to that of a computer. The maximum calculation speed is as high as 500 million operations per second. He is most suitable for large-scale calculation work. Although it is very laborious to crack the future asymmetric cryptography systems of various countries,
Compared with other codebreakers who only rely on human calculations, their own advantages are not that great.
This plan is one of many plans that Yu Hua constructed based on the historical information in his mind.
Those who are good at fighting will be in an invincible position without losing the enemy.
Only by having information first can you be invincible.
"Did you think of these yourself?" His eyes glowed,
There was a storm in his heart. Hua Luogeng was shocked by the plan of his good apprentice. He took several deep breaths, suppressed the emotions in his heart, remained calm, and nodded after thinking for a few times.
Yu Hua's super computing power has been perfectly demonstrated in the red secret deciphering work. This is a computing power that even he cannot match. With such computing power, it is indeed possible to break asymmetric codes.
Because the premise of cryptography is that no password is absolutely secure.
Hua Luogeng never expected that his good apprentice would have such talent.
Yu Hua replied: "Students are not talented. I thought about it for several days and nights before I finally came up with this."
"..."
The corner of Hua Luogeng's mouth twitched slightly, why did these humble words sound so harsh.
Gu Zhai
"However, the student's academic level is not enough. Master, you need to continue to teach and study knowledge." Yu Hua continued: "The student can't wait for the journey of number theory."
Insufficient academic level and knowledge reserve are still Yu Hua’s biggest problems.
"Let's take the exam first. When you're done with this period of time, you can come to Tsinghua University to take classes. Since you have such ambitions, you can't be lax. If you want to become something great, you must study hard first." Hua Luogeng said seriously.
"Students, please remember." Yu Hua bowed and saluted.
Hua Luogeng reminded: "Also, don't talk about today's words to anyone else. They must be kept strictly confidential. Do you understand?"
"Understood." Yu Hua nodded.
Afterwards, the master and apprentice, who had a close exchange of ideas, separated. Yu Hua faced his exam seat. Time passed by, and students who took the entrance exam for Tsinghua's recommended students gradually arrived one by one. These students all came from prestigious universities, and many of them
A person from the High School Affiliated to Beijing Normal University.
The exam was held at nine o'clock in the morning. Soon, the first batch of fifteen recommended students from Tsinghua University all arrived. When the exam time came, Hua Luogeng, who served as the invigilator, was responsible for distributing the test papers.
The entrance exam for recommended students is not very difficult. There are only three test subjects - Chinese and Mathematics. For all recommended Tsinghua students present, this entrance exam is essentially just a one-step process.
After the three exams, the written test session ended. The test papers were collected and reviewed on the spot. All students, without exception, passed.
After lunch, all recommended students faced the important interview session in the afternoon.
Tsinghua Academy, second floor.
Yu Hua, who ranked first in the written examination, stood in front of a classroom door, tidied up his appearance briefly, and gently knocked on the door in front of him.
"Please come in." A middle-aged man's voice came from inside.
"Squeak!" There was a scratching sound from the door. Yu Hua pushed the door open and walked into the classroom. After closing the door, he looked at the desks lined up in the middle of the classroom.
Behind the desk, there are four middle-aged men in formal suits sitting. They all have different looks. Some are thin, some are fat, some have meticulous faces, and some have smiles. Apart from their looks, they also have different temperaments.
different.
Elegant, reserved, gentle and serious.
These are the four gentlemen who are responsible for the interview. As expected, they should be professors from National Tsinghua University.
Yu Hua looked at the four gentlemen carefully, his pupils shrank, his face showed respect, his back straightened, he walked forward, stopped not far from the desk, bowed and saluted: "Recommended student Yu Hua, I have seen these four gentlemen.
Sir."
Mei Yiqi, Wen Yiduo, Chen Yinke, Ye Qisun.
This is the lineup of today's interviewers. The level of luxury is unimaginable. Yu Hua did not expect that today's interview would be conducted by these four big guys.
Mei Yiqi, forever the president of Tsinghua University.
Wen Yiduo, a great master of the Republic of China, was the editor-in-chief of the Journal of Tsinghua University at that time.
Chen Yinke is a full professor in the Departments of History, Chinese and Philosophy at Tsinghua University. He is also a director of Academia Sinica, leader of the first group of the Institute of History and Linguistics, a director of the Palace Museum, and deputy editor-in-chief of Tsinghua Journal. He is a professor among professors and a master among masters.
, his academic attainments in the field of literature are so high that no one can match him.
Ye Qisun, dean of the School of Science at Tsinghua University, founded the Department of Physics at Tsinghua University, is the founder of modern physics in China, and is the mountain of Beidou in the Chinese physics community. If he lightly stomps his feet, domestic physics will be shaken by three points.
The four people in front of me are top celebrities in history, true masters.
This is a super luxurious interview group composed of four people!
