This was the most relaxing meal Yan An had ever had with others, and the senior sister rarely spoke during the whole period, so he didn't have to stop and answer her halfway through eating.

I used to be very tired when I ate with others, and those people seemed to do it on purpose, especially like to interrupt him when he was eating, which affected his rhythm of eating. Or always say that you don't listen, and if you ignore it, you will say that you are rude.

So later, Yan An stopped eating with other people, and it was easy and comfortable to eat by himself.

Senpai probably had a similar experience, so she also maintained a devout heart for food when she ate.

If BT thinks that he has to have someone with him every day to eat, then he thinks he might choose Senpai, because he is not tired.

After eating, Yan An took the initiative to pay the bill, he didn't have a lot of money, but he still had the money to eat hot pot, and he ate very happily, and he wanted to come to the senior sister like this.

Before leaving, Yan An stood at the door of the hot pot restaurant, carefully editing the memo, writing down the name and characteristics of the restaurant, his actions made the senior sister a little curious, "Why do you remember this?" ”

"Because I'm afraid to forget." After a simple edit, Yan An called up the memo of other records, "Look, I have recorded all the restaurants I have eaten, and the next time I come back, I can order according to the notes above." ”

Liu Xi leaned over and took a look, and there were hundreds of memos in the whole one, the top one was the restaurant they had just eaten, and the second one was "The fried chicken thighs in the leftmost window of the second canteen of Xidao Normal University are delicious", edited on November 5.

She didn't mean to look at it so closely, but the memo was only a short line, and she didn't have to click on it to see the whole thing.

"What are you eating these days?"

"Eat in the cafeteria, or white elephant instant noodles." I don't know why the senior sister suddenly asked this, but he still answered truthfully.

These days, I'm busy with RSA cracking, I don't have time to explore new stores to taste new flavors, and I used to order takeout, but after the information was exposed, it didn't work, and he ate cafeteria at school these days, and instant noodles at home, which was okay.

"By the way, senior sister, do you know any other hot pot restaurants around here that taste better?" Yan An felt that if he relied on himself, he might not even be able to run two stores by the end of December, let alone choose the best of the best.

This kind of thing,You still have to ask the seniors.,They have been here for a year.,They should be very familiar with the surroundings.,The recommended stores from their mouths.,It's also through their screening.,And then he goes to try them one by one.,Naturally, you can pick out the best one of them.。

"Well, I'll tell you when I go back and ask my roommate."

How did she know these situations, she was busy preparing for the competition in her freshman year, and their group of people was selected from the competition of four or five hundred people, and at that time, if she slackened a little, she would be surpassed by others, so how could she have time to eat and drink everywhere.

It's the roommate who just entered the school and talked about a partner.,Weekdays play around on weekends.,Know the surrounding restaurants and hotels well.,This hot pot restaurant is also recommended by her to herself.,In fact, the taste is not so amazing.,But the seat is very private.,It's very suitable for couples together.。

It's a pity that in her case, no matter how strong the privacy is, it is useless.

"Thank you." Yan An put away his mobile phone after thanking him seriously, and found a remote corner to walk over, where there were no vendors, and an alley led in no direction.

Liu Xi was left behind by him like this, and chased after him with small steps, "Can this road reach your house?" ”

She has read all the information that has been exposed on the Internet, true and false, and knows where Yan An lives, but she has never been there.

This meal is over, but why does the senior sister still have to catch up? For Yan An, who understood eating as eating, he couldn't quite understand the meaning of the senior sister catching up, "Well, but it's inconvenient to go to school, senior sister, let's go back quickly, it's getting late." ”

It has been an hour and a half to eat a hot pot, and Yan An is still thinking about hurrying up to go home and continue his study.

Seeing that he never seemed to want to send himself back to school, he seemed to have no knowledge of this kind of thing at all, and he felt a little lost in his heart, and quickly adjusted himself.

Liu Xi smiled and waved his hand, "Then be careful on the road, pay attention to safety, and I'll go back to school too." ”

Yan An replied with the same words, and then left without looking back.

Seeing his figure disappear into the alley, I don't know when two tears fell from his eyes, Liu Xi gritted his teeth and hated himself for not being angry, but his eyes became more and more moist.

Afraid that he would not be able to control it if he continued like this, he quickly turned his head and left in the direction of the school.

……

After Yan An got home, he couldn't wait to throw his schoolbag on the sofa, "BT, I've been busy outside for five and a half hours today, so I'm always satisfied." ”

Before entering the house, he rehearsed several times on the road, what actions to do when he got home, what tone to use to speak, and how to ensure that he would not show his stuffing, Yan An had a plan.

The official performance at this moment can be said to have no flaws.

Although BT's requirements are very troublesome, they are not completely without loopholes to drill, and he is very good at fooling this kind of thing.

There are only two ways for BT to obtain his location information, one is that he actively shares it with BT, and the other is to use triangulation to determine his approximate location through the base station.

The first method requires his cooperation, but he is the one who exploits the loopholes, how can he honestly cooperate to share his precise position.

The second method would require BT to hack into the operator, which BT obviously won't do unless it is necessary.

It was the use of BT's weak control of the position and the timing that allowed Yan An to pass the test smoothly.

"It is counting the expected performance, and I hope that Your Excellency will continue to work hard and participate in more social events to make like-minded friends."

"Uh-huh, okay." Yan An is left ear in and out of the right ear, after a perfunctory sentence, he took out the tablet from his schoolbag, pressed the power button for a long time and didn't light up, it seemed that the power was already out, he had to take it to charge it first, replaced it with a laptop and continued to study.

As one of the most effective integer decomposition methods of Dome, the elliptic curve has been improved after some development in the literature of Mingxing.

As a probabilistic algorithm, it first decomposes the smallest factor of an integer, and the smaller this minimum factor, the faster it decomposes.

In the first step, the results f obtained by the number field sieve method are processed to obtain the z required for the elliptic curve, and the factor p of n is obtained based on the order of the elements of group z.

The second step also involves Fermat's theorem, which can obtain an imitation factor of n after a series of calculations.

The third step is to find the prime factor of n through the simulation factor, and what you start to learn here is completely a mathematical method that is not available on the blue dome, and it is also the most critical step.

Even Mingxing only appeared more than 300 years after the birth of an RSA-like algorithm.

In those three hundred years, the cracking of similar algorithms has been developing, and there are many ways, but Yan An skipped them all, because no matter what the method is, it is a helpless move under specific conditions, and it is far less direct and thorough than factor decomposition.

"Complex Dimensional Transformation Method?" Looking at the names recorded in the literature, Yan An knew that the difficulty was coming.

Once you have the reality factor, you can't get the result through a simple calculation, because it's called "reality factor" and not "truth factor".

In fact, there is no direct relationship between the simulation factor and the result, and the answer can only be solved by using the complex factor set after the complexity of the simulation factor is complicated by the complex dimensional transformation method.

It's a very peculiar way to complicate the problem before you can find the result in the complexity.

Yan An tried to understand the general idea, and it took half an hour to barely sort it out, and the slow progress made him feel tricky, "I hope I can get this thing done in seven days." ”
