Chapter 459 Cracking the code, a turbulent international event


Tangdu Jiaotong University.

After receiving the call from Xu Songyao, Wang Donglai returned directly to Tangdu Jiaotong University.

While going upstairs to Xu Songyao's office, Wang Donglai suddenly noticed a black car with a special license plate.

Suddenly, Wang Donglai had a feeling.

This car may be coming for him.

With such a strange and nonsensical guess, Wang Donglai entered Xu Songyao's office.

After seeing the situation in the office, Wang Donglai’s first thought was that he had guessed it right!

I only saw a few people in the office.

As the president of Tangdu Jiaotong University, he still has the home field advantage within the school. Logically speaking, the momentum should be stronger.

But in fact it is just the opposite!

Xu Songyao's momentum was at a disadvantage.

I saw a slightly reserved and nervous look on his face as he faced the visitor.

"Hello, Academician Wang, I am Ding Liang from the Department of Mathematics of the National Defense University."

Ding Liang, wearing military uniform, walked in front of Wang Donglai and looked Wang Donglai up and down quickly with sharp eyes. After a while, he gave a military salute and introduced himself in a loud voice.

Yes.

This time, the person who appeared in front of Wang Donglai was a professor from the National University of Science and Technology.

The special license plate Wang Dong saw downstairs before he came was also for this reason.

"Hello, I am Wang Donglai!"

Wang Donglai nodded seriously and said hello.

After greeting Ding Liang, Wang Donglai looked directly at Xu Songyao, with a sincere smile on his face, and said: "Xu Xiao, did you come to me to do anything?"

Hearing Wang Donglai's question, Xu Songyao explained aloud: "It's not that I have anything to do with you, but that Director Ding has something to do with you..."

Xu Songyao just said this, Ding Liang nodded, admitted directly, and said loudly: "Academician Wang, With all due respect, I should have contacted you directly, but some contents and areas are relatively sensitive, and my identity is even more obvious, so I have to publish this volume. I hope you will forgive me.”

Wang Donglai’s eyebrows wrinkled slightly, then calmed down in an instant.

"Did Director Na Ding come to see me for something?" Wang Donglai asked straight to the point.

Hearing this question, Director Ding hesitated for a moment, then made a decision and said: "Academician Wang, I think the whole world knows about your achievements in the field of mathematics. I don't know how you did it. What about cryptography? ”

"Oh, cryptography?"

"I think it's very interesting!"

Wang Donglai directly expressed his inner thoughts without any attempt to beautify it.

After hearing what Wang Donglai said, Ding Liang’s expression remained unchanged and he continued to speak: “That’s it, Academician Wang, I now have a password in my hand. If Academician Wang can complete it within the limited time, crack, then I think Academician Wang is qualified to know the inside story."

"So, I wonder if Academician Wang is willing to try it?"

When Ding Liang said this, Wang Donglai suddenly became interested.

"Okay, let's give it a try!"

Ding Liang was not surprised by Wang Donglai's choice, and directly took out a document from the briefcase and handed it to Wang Donglai.

Wang Donglai did not open it to check it immediately, but asked a rather strange question.

"Director Ding, the document I am looking at is not a confidential document. Is it necessary to sign a confidentiality agreement or something like that after reading it?"

Ding Liang was stunned for a moment, and after he came to his senses, he waved his hand and said: "Of course not!"

Wang Donglai nodded and said aloud: "Okay, with Director Ding's words, I felt like it. Don’t worry!”

After saying that, Wang Donglai directly opened the file and looked at it.

There is not much in the file. With Wang Donglai's ability, he just read it for a while and wrote down everything in the file.

At the same time, Xu Songyao put a pen and a stack of paper in front of Wang Donglai regardless of his majestic status as principal.

"Swish, swish, swish..."

Wang Donglai took the paper and pen, and the pen tip immediately crossed the paper, outlining the numbers one by one.

Seeing Wang Donglai move so quickly, it only took less than a few minutes.

Ding Liang's eyes showed a hint of expectation, but also a hint of doubt.

Does Wang Donglai really understand, or is he pretending to understand?

Ding Liang couldn't be sure for a while.

Time passed by in this atmosphere.

After Wang Donglai finished writing the last stroke on the paper, he raised his head, looked at Director Ding and said, "Director Ding, how do you think I can crack it?"

With that said, He handed the password he worked so hard to crack into Ding Liang's hands.

Ding Liang did not hesitate and started checking immediately.

And this look caused a look of surprise to appear on Ding Liang's face.

Ding Liang really didn’t expect that Wang Donglai would be so strong.

He is very clear about how difficult the password in his hand is.

In order to crack this password, I don’t know how much labor and time was spent.

In the end, the crack was completed with the assistance of super computers.

After making a mental evaluation of Wang Donglai's ability, Ding Liang's lips curved slightly.

"Academician Wang, do you remember what I just said?"

"Currently, there is a highly confidential project that needs to crack a password. The time is tight and the task is heavy, so I thought of Academician Wang, the youngest in the country Academician."

"To be honest, the higher-ups still value Wang Donglai very much."

"Academician Wang's performance just now proves this, so I am now the official representative. …”

Before Ding Liang could fully express his intention, Wang Donglai stretched out his hand to signal Ding Liang to stop.

"Director Ding, I still said what I just said."

"Confidential projects, confidentiality agreements, I know all these."

"Director Ding might as well use it first It doesn’t involve violating confidentiality. How about explaining what I need to do?”

Wang Donglai said what he meant calmly.

In his expression, he didn't seem to be worried at all that Ding Liang would be angry because of his interruption.

“Okay!”

After taking a deep look at Wang Donglai, Ding Liang agreed as expected.

After pondering for a while and thinking about it in his mind, Ding Liang said aloud: "Does Academician Wang know the MD5 encryption algorithm?"

Wang Donglai nodded and said, "Of course I do. It is a message digest algorithm promulgated by the Bald Eagle Bureau of Standards and Technology and is a widely cited cryptographic algorithm. ”

"The MD5 message digest algorithm belongs to the Hash algorithm. It operates on the input message of any length and generates a 128-bit message digest."

"The technical principle is not very complicated. First of all, Data padding, padding the message with data to make the length of the message Modulo 512, we get 448. Let the message length be After the step result, the length of the original message is filled in, which can be used for storage. The length is 64 bits. If the message length is greater than 264, only the lower 64 bits are used, that is, the message length is modulo 264. After this step is completed, the final message length is an integer multiple of 512. ""Third. The first step is data processing, which requires the use of four constants: A=0X674 52301, B=0X0EFCDAB89, C=0X98BADCFE, D=0X10325476, and four other functions..."

After mentioning the MD5 cryptographic algorithm, Wang Donglai immediately started talking. .

Seeing that Wang Donglai was so familiar and showed a trace of confidence unconsciously, Ding Liang became more and more excited.

“Academician Wang is right. In view of the various characteristics of the MD5 cryptographic algorithm, it has a wide range of uses.”

“And our ongoing project is trying to crack this Set a password."

"To solve such a problem, there is a prerequisite and a must, that is, a top mathematician is needed as the core."

"And this core. , maybe everyone has his own idea.”

"However, in my eyes, Academician Wang is currently the top mathematician in China and even in the world."

Be able to prove mathematical problems in multiple research directions in a very short period of time .

No one can deny this iron-clad academic achievement.

“Academician Wang, that’s all I can say.”

“If you want to know more, I’m afraid you need to sign a confidentiality agreement.”


Ding Liang kindly gave Wang Donglai a reminder.

Hearing what Ding Liang said, Wang Donglai thought quickly for a while, and soon had a rough guess.

If it were another time, Wang Donglai might not be able to guess it.

But it happened to be at this time, no matter how slow Wang Donglai was, he knew that a big event was about to break out in the South China Sea.

Although there is no evidence to confirm, he just feels that his guess is not wrong.

Thinking of this, Wang Donglai couldn't help but become excited.

At this level, there are not many things that can make him feel challenging.

Cracking the password is, to a certain extent, a challenge for him.

The greater the challenge, the more it can stimulate Wang Donglai’s own potential and fighting spirit.

Now that he had guessed it in his heart, Wang Donglai said aloud: "To be honest with Director Ding, I have only read a few books on cryptography, and I don't have much real practical experience."< br>


"Now that Director Ding has invited me, I have to give Director Ding face."

"I am willing to participate in the cracking of the MD5 password algorithm!"

Although I have guessed in advance that Wang Donglai will probably not If he would refuse, he would definitely agree, but when Wang Donglai really agreed, Ding Liang still felt a big stone fall in his heart, and he became more comfortable.

"Academician Wang, I have two more things that I must make clear to you."

"It concerns the MD5 cryptographic algorithm system, and the higher-ups attach great importance to it."

"So, the research time left for us is not generous."

"We need to stay silent for at least half a month, or even be unable to contact the outside world for a month. Is it possible for Academician Wang to do this?"

"Also, then It is something that was seen in the project team and must not be spread outside. If it breaks the law, you will be punished by law!"

"Academician Wang, without further ado, how about we talk while we are walking?"
< br>Ding Liang suddenly persuaded Wang Donglai like this.

Wang Donglai naturally had no objection, so he nodded in agreement.

"Principal Xu, thank you very much for your cooperation. What I have to do has been done, and I will leave now."

Ding Liang said goodbye to Xu Songyao with a smile.

Seeing the genius from his school being taken away by Ding Liang, Xu Songyao felt a little strange at the moment.

However, these emotions were quickly suppressed.

"Director Ding, you're welcome. We will do this no matter where it is."

Xu Songyao replied politely and stiffly.

Soon.

Wang Donglai and Director Ding got into a car with a special license plate, left Tangdu Jiaotong University, and headed for the Qinling Mountains.

On the road.

"Academician Wang, in the next period of time, we will be busy at the base with cracking cryptographic algorithms. In addition to its importance, we may not be able to communicate with the outside world for a long time."

“Academician Wang might as well comment on the next development of Galaxy Technology Make arrangements to avoid any problems in the development of the company."

"In addition, you can also tell your family to avoid worrying about it, as long as you don't mention confidential and sensitive content."

Ding Liang took the initiative to speak out and said this to Wang Donglai.

"Thank you, Director Ding. I have my own arrangements for the company."

"I believe that even if I am away, it will not affect the development of the company."

"As for my family, they also support my work. They don't ask about some things, and they don't ask me questions in a measured way. Go mention it, so you can rest assured."

Wang Donglai said with a smile.

Ding Liang nodded and said aloud: "Academician Wang, at this time, I will not hide anything from you. What should be said must be made clear."

"At the base, we Just do your job well and crack the DM5 password as soon as possible.”

"Other things are beyond our control!"

"In the base, it is better to be cautious in your words and deeds!"

What Ding Liang said was not very clear, but But Wang Donglai could hear what the real meaning was.

And in this way, Wang Donglai’s guess before he was even more confirmed.

Know yourself and the enemy, and you will be victorious in every battle!

This is the purpose of the above to expedite cracking of the DM5 algorithm password.

Wang Donglai nodded and said nothing more.

At this time, he was already thinking about what he could do in this matter.

My mind was frantically recalling the various reports on the 2016 South China Sea incident in my past life, as well as the various information posted on the Internet that was difficult to distinguish between true and false.

The news was peeled off one by one, and a general situation soon formed in Wang Donglai's mind.

With this relatively clear cause and effect, Wang Donglai quickly made a decision.

It’s okay that I don’t have the ability. Now that I have this ability, how can I be the same as in my previous life?

Thinking like this, Wang Donglai had already made a decision in his heart.

Thanks to Wa's existence, although Wang Donglai does not show up in the company, he can still manage the entire company to a high standard without making mistakes.

In Galaxy Technology, even many people did not know that Wang Donglai was no longer within the company, but secretly went to a confidential base to crack the password.

Time passes.

Internationally, a rather bizarre news report suddenly appeared.

The small country sued a big country? (End of this chapter)
