Yan An's eyes were clear, and when he said this, Gao Shenghan couldn't see any trace of hesitation in it.

He really thought so, and refused just because he didn't want to go to Liangxi.

It is this kind of willfulness that actually makes Gao Shenghan feel real, inexplicably in line with his certain cognition, there is an illusion that things should be like this.

How can a person who can come up with an effective RSA search algorithm rush to join them, the real situation should be the other way around, they are begging others to take them to do research.

From the fact that Yan An only sent them the RSA effective search algorithm and then inferred that he wanted to join the five or six institutes, this idea seems to be a bit too self-indulgent.

However, as Zhu Chi's first-class and top-notch computer technology research unit, they seem to have the confidence and reason to be so popular.

"Is it just because you don't want to go to Liangxi? This is a great opportunity and I hope you will give it another thought.

You should know no less about RSA encryption algorithms than we do, and the RSA effective search algorithm you gave us has opened up a new path, and I can reveal some information to you.

The institute intends to set up a special group to conduct research and expand the effective search algorithm of RSA, and strive to expand the cracking range from 1024 to 2048 and beyond.

And this project team needs to have a team leader, although you are still young, please believe me, as the proposer of the algorithm, no one is more suitable for this position than you, if you are willing to come......"

Identity and background are not so important at this time, the most important thing at the moment is to win over Yan An and confirm his whereabouts.

If he just stays in Nandu, it won't be a big problem, but if he goes abroad to join the research institute of another country and contribute to the construction of cryptography in other countries, it will be a big trouble.

In this regard, Gao Shenghan did not hesitate to promise the position of a team leader, although he was not even a team leader, but he was sure that it was more than enough to be a team leader with Yan An's contribution.

It's a pity that Yan An refused, "I just want to stay in Nandu, and I'm too lazy to run too far." As for projects that specialize in RSA algorithms......

To be honest, I'm not interested in decrypting anything, I yearn for the sea of stars.

If it weren't for Wu Juren, I wouldn't have done this. ”

What he said was the truth, but Fan Yanan wanted to go farther, with his learning ability, even if he messed around every day in high school, as long as he didn't control his scores, he could choose the top universities in China.

It's just that he doesn't want to go anywhere, all the volunteers fill in the local colleges and universities in Nandu, and the educational resources are indeed much worse than those of top universities such as Shuimu, but for Yan An, this does not affect his choice.

The reason is not complicated, because the body of BT is here, and the property certificate in the commercial street inherited from the inheritance to him, and the body of BT is placed in the shop.

If he is too far away, it will be inconvenient to grasp the situation here, and the contact with BT is not convenient in Nandu.

For example, to add a new functional module to BT, he has to go to the shop to use the captain's authority to add, modify and other operations, which cannot be carried out remotely through the network, and once Yan An leaves the city and the province, it will become very troublesome.

This reason made Gao Shenghan completely speechless, he found that his thinking mode was still too complicated, and the habits he developed in the military school made him complicate things and couldn't adapt to Yan An's simple ideas.

"Wu Juren?"

However, the first half of his sentence can be understood, as for the reason for studying the decryption algorithm in the second half of the sentence, it is too jumpy that Gao Shenghan can't keep up, "Just because he criticized you on the Internet?" ”

Through the descriptions of teachers and classmates such as Zhang Niansheng, it is impossible to find that Yan An shows interest in decryption on weekdays, and there is no indication that he has learned decryption during the preparation for the competition.

In other words, Yan An's research on decryption algorithms is very likely to have been carried out after the completion of the ACM competition, and Yan An's personal admission at this point in time makes it difficult for him not to think that this is Yan An's response to the denunciation boom provoked by Wu Juren.

But why cryptography? Is there any necessary connection between the two? Or does Yan An just want to prove himself?

At that moment, countless thoughts flashed in Gao Shenghan's head, but he was still puzzled, until Yan An replied to him with a calm tone of "small belly chicken intestines".

"Yes, because of this, I'm just cautious, and I like to retaliate. I'm giving you the RSA effective search algorithm just because I want you to find someone to look it up. ”

There is no need to make any excessive demands, Wu Juren's foundation is not clean and cannot withstand investigation.

You just need to make this happen, and with a little care, you can find out a lot of things.

As a result, Gao Shenghan was silent, he was in the research institute and not the intelligence department or the security department, everyone was not in the same system, and it was very difficult for Yan An to ask him to help with the operation.

"I can give it a try for you, but I still want you to come to our institute for this project."

It's one thing to feel not interested, it doesn't affect what Yan An does, and those who say they don't love money are not slow to collect money in their hands.

In terms of Yan An's talent, letting him do what he is interested in instead of decrypting it is tyrannical to destroy heavenly things.

It's a pity that Yan An's head was still changed back, "I'm really not interested, and I don't want to leave this city." ”

To be honest, I have never encountered this situation, even if he said that he needed a lot of money was not a problem, but it was this sentence that made Gao Shenghan and Li Junwei feel tricky.

If Yan An's political level is not the masses, then he can still make demands on him from the organizational level.

But he is the masses, and when everyone in the university wants to improve their political level, he is the only one who is unmoved, and does not seem to have the slightest interest in these "miscellaneous matters".

"If you really have an urgent need to crack RSA encryption, you can give me some time, and I'll send it to you when I finish the factorization algorithm."

Yan An just mentioned it casually, but the entire living room fell silent for a long time after he finished speaking, until the silence was broken by the sound of Li Junwei swallowing saliva.

So-what they dream of is so worthless in Yan An's eyes?

There had never been such a moment, and in a trance he felt as if he had returned to the days of studying in the Regency country in the ninety-fourth year, and in his eyes the novelty of affairs had become accustomed to the people of the Regency, but it was him, the Zhu Chi man, who made them feel novel.

I still remember that when I followed the mentor to ask questions, when he was complacent about the advanced things he had learned, the tutor could throw out more advanced technologies at hand, which had a great impact on him at that time and made him wake up.

Compared with Zhu Chi's advancement, what he can learn and what his teacher gives casually is just a technology that has been eliminated in the country.

But even so, he still has to regard it as a treasure, because what he has learned, no matter how backward he is in the Regency State, it can come in handy after bringing back Zhu Chi, opening a door for Zhu Chi to catch up with the Regency State in the future.

He will never forget the feeling of being behind people everywhere, the advanced for him is backward to be eliminated in the eyes of others, and he lived like Grandma Liu entering the Grand View Garden during that time, and he doubted himself more than once, doubting whether Zhu Chi could catch up.

Fortunately, in the early morning of April 20, 94, the Computer Network Information Center of the Zhu Chi Academy of Sciences conducted a simple email sending and receiving with the state of Kan Regent, marking Zhu Chi's official entry into the Internet age, allowing him to see a glimmer of hope, and resolutely returned to Zhu Chi after completing his studies, so that what he had learned could be displayed in the motherland.

The situation in front of them is so similar to those years, they think that the RSA effective search algorithm that Yan An came up with is very advanced enough to refresh their cognition.

Although it could only be used in the field of intelligence to decipher ciphertexts from a decade ago, it represented a major breakthrough in the field of cryptography, opening up a whole new way for them to decipher with algorithms that could be done by ordinary computers.

They come here for this, believing that this is the most advanced and efficient cracking algorithm in the world today.

As a result, Yan An said lightly, give him some time, and the factor decomposition algorithm can be figured out.

Listening to the name, you know that the goal of the crack is not to simply change from 1024 to 2048, but to give the entire RSA encryption algorithm to a pot.

This brought Li Junwei no less shocking feeling than back then, and the factor factorization algorithm that Yan An said from his mouth did not seem to be what mathematicians had been striving for in the past thirty or forty years, and in his mouth, it was like the eliminated technology could be disposed of at will.

Just when he was still in the clouds, Gao Shenghan instinctively sensed the trap in this sentence, "Can the factor factorization algorithm be solved without a limit of digits?" What equipment do you expect? If it's 4096-bit encryption, how long does it take to crack it? ”

Theoretically, quantum computers can accomplish this, but with the current state of technology, it will take them seventy or eighty years to crack a key.

Obviously, this is meaningless, and strategic intelligence between countries may still have a certain value in ten or twenty years, but when this period is extended to seventy or eighty years later, even the most important information will become a pile of waste paper, and even they will not need to declassify it, and after a certain period of time, governments may publish it on their own.

If the factor factorization algorithm mentioned by Yan An is also like this, it can only be said to have reference value, and the practicability is not as good as the RSA effective search algorithm.

The RSA effective search algorithm can decipher the ciphertext from ten years ago, and it is very convenient, and the intelligence department can find a computer on its own.

Yan An hesitated when he was about to answer.

He already has a preliminary understanding of factorization algorithms, and there are four or five kinds of factorization algorithms that can be accessed in the BT database at this stage, each of which contains different mathematical ideas.

Although they can all be used, there are quite a lot of differences between different factorization algorithms.
