The algorithm was reported, and it was necessary to give the upper management a certain amount of time to react, and Gao Shenghan's contact work was started after the meeting.

Transferring Yan An's household registration information was originally the simplest and most basic one-step review, and it was generally enough to casually look at it twice to confirm that there was no case record between the immediate family members, and that I had no bad records.

But Gao Shenghan found a lot of things wrong in this audit, and Yan An even had doubts about these basic information.

For example, he was only registered in 2003, when he was five years old, and he was a black household before that, which is not at all reasonable.

In the second year after having a hukou, Yan An met the requirements for primary school in terms of age, but he continued to repeat a grade in the first year after going to school, and he was not promoted to the second grade until three years later.

When he saw this record, Gao Shenghan's first reaction was disbelief, the genius who could crack the RSA encryption algorithm actually repeated the grade for three consecutive years in the first grade of primary school?

Is it a mental illness? That's why I will repeat the grade continuously.

The impression that autistic people may be sensitive to numbers is a stereotype of Gao Shenghan, because the movies he watched when he was a child made him remember this "setting" deeply, so that he came into reality from time to time.

In addition, there are some noteworthy strangeness, Yan An clearly had parents when he was registered, but after two years, his parents were inexplicably gone.

Well-the meaning is very simple, that is, the records on the paper information are gone, since 05 Yan An's household registration book information is only his name, his parents are unknown, he looked through and found that there is no record indicating whether they are missing or deceased.

This is a very doubtful point, and more importantly, in this case, Gao Shenghan did not find any record of Yan An receiving any financial aid, as if he never needed to spend money to go to school and live.

Until he was eighteen years old, he suddenly had an extra deposit of 10 million yuan in his name and a real estate certificate in a commercial street because of "inheritance".

It's all so suspicious, but anyone can see that something is wrong, but this basic information full of loopholes, because no one has ever paid attention to it, and no one has specially investigated him, which has made him live a low-key life for so many years.

Gao Shenghan leaned back in the chair and his head was big, all kinds of signs showed that Yan An's foundation was not clean, there might be foreign forces behind it, and it was likely to be a chess piece that the enemy had planted since he was a child, but he couldn't find evidence.

All of this is based on reasonable suspicion based on the results of the existing investigation, and ordinary people can be killed if they have any suspicion, and they want absolutely clean people, not a time bomb.

But this person is the cracker of the 1024RSA encryption algorithm, and the institute is counting on him to lead everyone to continue cracking the 2048RSA encryption algorithm.

This identity made Gao Shenghan have to think twice, they can't miss such a talent, and they can't accept a bomb in a daze.

"No matter, let's see someone first." Gao Shenghan no longer hesitated, took Li Junwei and set off immediately after booking a ticket to Nandu, and departed at 3 o'clock in the afternoon by high-speed rail, and arrived at 8 o'clock in the evening.

As soon as he got out of the car, Gao Shenghan rushed to Nandu University non-stop, but he fell short.

The school was completely unprepared for their arrival, and Yan An, who was supposed to study at night, was also exempted from morning exercises and evening self-study by Dean Wang because of the championship in the competition, and no one could be contacted by phone.

However, Gao Shenghan got the address left by Yan An when he went through the day school procedures from Yan An's counselor, and it was not a trip in vain, and by the way, he was able to get to know Yan An through the school.

"Yan An is just proposing a new structure, and the paper hasn't been published yet, so it shouldn't alarm you, right?"

Zhang Niansheng looked at Gao Shenghan and Li Junwei suspiciously, if it weren't for Dean Wang to prove that there was no problem with their documents, he would have suspected that these two people were here to deceive.

Nandu University has an intersection with the military department, but that is a matter of the School of Materials, and the intersection between the letter academy and the military department is probably limited to students signing up to join the army.

Hearing Dean Wang say that they are a certain research institute affiliated with the Ministry of Military Affairs, this is even more puzzling.

I haven't dealt with each other on weekdays, so why did I suddenly come looking for someone.

"Naturally, we came to him for our reasons, and this aspect involves confidentiality, so it is inconvenient to tell him."

The one who led the exchange was Gao Shenghan, although he was the youngest one, but because he was born in a military academy, he had a strong momentum, and he was more professional in collecting intelligence than Li Junwei.

"Then why are you coming to me again?" Zhang Niansheng glanced at him, as well as Li Junwei, who had a thoughtful and meditative expression on his face beside him.

From the moment the two met, Li Junwei had that expression, as if he was thinking about something important.

"We hope to know some details about Yan An's classmate through you, according to our investigation, we found that his background information is vague and there are traces of artificial forgery. We suspect that he has contacts with foreign powers......"

Zhang Niansheng's pupils suddenly dilated several times, and he immediately interrupted Gao Shenghan's words in a panic, "Foreign forces? How is this possible! ”

He didn't believe what Gao Shenghan said, because it was too ridiculous and completely unfounded.

How could a hard-working student suddenly become involved with foreign forces.

Besides, in the two months that he has been studying with him, Yan Anke has not shown the slightest abnormality - if he always says that he is an alien and the operation of naming an inspirational idea in his head does not count.

"Don't get excited, we are just here to understand the situation, contact with foreign forces is only a possibility, what is the actual situation, we need further analysis."

Gao Shenghan patiently said that a lot of information can be analyzed from people's first reactions.

This kind of immediate rebuttal of the brain represents Zhang Niansheng's absolute trust in Yan An's innocence, and it can be seen that Yan An's performance in the two months of studying with Zhang Niansheng is nothing unusual.

The two exchanged a few more words, and in the evaluation of Yan An, Zhang Niansheng repeatedly emphasized praise words such as diligence, high talent, jumping thinking, and strong inspiration.

This did not make Gao Shenghan feel at ease, on the contrary, it made him even more worried.

There is nothing special about these evaluations, and he can get such evaluations when he goes to high school and finds any student in the top five of his class, which does not reflect the qualities of a researcher.

Gao Shenghan also inquired about the process of proposing the phase data structure, and found that it was similar to the proposal of today's RSA effective search algorithm, and suddenly, without the slightest warning, it was directly taken out.

No one knows when, how, or how he did it.

It's as if his research is nothing more than the realization of a random idea in his mind, and the finished product is the result without a process, which is completely opposite to the normal research process of a normal researcher.

In particular, the proposal of the RSA effective search algorithm, which is the most difficult to understand, has been studied for so long, and has been investing energy into it for several years, but it has been easily solved by one person.

If it is said that the phase data structure and phase jump algorithm are what Yan An has been conceiving since he came into contact with programming at the beginning of school, then the two months in between can be called research time.

But this RSA effective search algorithm, assuming that he started research after the end of the ACM competition, and it will only take 12 days to complete today, can this be called research?

The dissertation proposal report has to be written for ten days and twenty days, and these twelve days of hard work are not enough to do, how can they surpass their research results in several years.

Not only surpassed, but also won this goal.

Gao Shenghan was puzzled, and could only attribute this to the fact that someone behind Yan An provided him with research results, and this person was not Zhang Niansheng, so it could only be a foreign force.

"These guys are really willing to give up the golden bullet and want to fight the golden phoenix......"

The more the enemy gives, the greater their goal.

It's just that Gao Shenghan still doesn't understand, is it necessary to spend such a big price just to support a college student?

There are tens of thousands of corrupted people in China, not to mention tens of thousands, and it is not easier to find a random researcher to hold it, and it is not easy to be suspected.

The atmosphere between the three of them was a little depressing, when Gao Shenghan didn't ask, Zhang Niansheng remained silent, Li Junwei still had that thoughtful and meditative expression, looking at his expression, it seemed that he was about to grasp the answer he had been looking for.

After a short silence, Li Junwei patted his head excitedly, "I remembered!" It's Senior Sister Shi......"
