Six days passed quickly, and with the concerted efforts of five people, the part of the cloud platform related to communication connection has been updated, which can greatly improve the stability of the connection under the condition that the existing hardware facilities remain unchanged.

If you feel that this is not enough, if you want to further improve on this basis, then you can only improve the hardware facilities, there are two roads, one is to do it yourself, but that is very time-consuming, even if Yan An can get a ready-made theory from BT's database, if you want to make a physical object, you have to wait for a long time. The second is to wait for others to develop it, this road is not full of uncertainty, at least in the cave demon project team, the project that Xu Wei started is related to communication hardware, and it can be applied after he improves the equipment.

Either way, you have to wait, Yan An felt that he had reached a satisfactory attitude after testing the stability and speed, so he no longer thought about getting the hardware thing.

Anyway, this kind of thing is always improvised, as long as it can be used. Human evolution is like this, as long as it can be used, then man-made things should naturally be the same. When the speed and stability are no longer enough for him, let's talk about improving the hardware.

However, six days is not enough time to get the supercomputer out, even if you add money, it is useless, the role of the banknote ability is gradually declining before the end of the year, not to mention that although the banknote ability is wonderful, it can't be used to accelerate the reality, even if you go to grab it, Xu Chen is already vigilant, and even the door of the computing center will not let Gao Shenghan take a step forward.

After hearing the news that he urgently needed to assemble a supercomputer recently, he couldn't wait to live in the supercomputer center with a fork, if Gao Shenghan dared to use his crooked brain, he would take Gao Shenghan to see Yan An.

Fortunately, their demand for supercomputing is not so urgent now, after all, it is the Chinese New Year next, and everyone has to rest, even if Yan An is not close to people, he has to consider whether it is not good to force them to work overtime on a good day that is only once a year.

Gao Shenghan assured Yan An that he could solve the problem of supercomputing before the Lantern Festival, so the other researchers' holidays were put on the Lantern Festival.

It's never so that they can play for a little longer.

Purely to squeeze them for the better in the future.

That's right, that's it.

Yan An nodded thoughtfully, and then waved his hand and let them go home.

However, only five people left in a hurry, and to his surprise, Gao Shenghan didn't leave, not only him, but also Wang Zhifang of the Ministry of Security, the guards sent by the Nandu Military Region to protect his safety.

There were even two guards standing guard at the entrance of the algorithm building.

"Don't you need to celebrate the New Year?" Yan An was still quite surprised, he thought that when the New Year came, everyone would go home for a reunion. In the past, at this time, all the shops went home, and if they wanted to have a meal, there were no restaurants open, so they could only make instant noodles to get by.

"Report! There will be a chance in the future! The soldier who followed immediately replied.

Nandu is not like the frontier that needs to be guarded at all times, and there is not so much military activity in the interior, so most people can still go home during the Chinese New Year.

There are a few like him, who need to stay to maintain the basic operation of the military region, and at this time, the unused annual leave can be accumulated and taken together with the next year, so that they can spend more and longer time with their families when they go back.

Needless to say, Wang Zhifang's home is in Nandu, and now it is considered overtime, and it is expected that he will have a good rest on Chinese New Year's Eve and the beginning of the year before coming out to work.

As for Gao Shenghan, Yan An couldn't figure it out the most, he worked in Liangxi before, and it stands to reason that he should settle down there, even if he didn't settle down in Liangxi, he should go back to his hometown, but at the moment, he stayed in Nandu as usual, and it didn't seem like he was going to leave.

"What about you?" Asked by Yan An, Gao Shenghan grinned smugly, "My home is here." ”

"Huh? When did you move? ”

tried to recall it in his mind, but Yan An couldn't remember when Gao Shenghan moved.

"Remember the last time I signed the non-disclosure agreement, I told you that the house next to your house was bought by our people? The director said that I will follow you in the future, and I will be responsible for helping you deal with most of the trivial things you encounter in research, as well as some things that are inconvenient for you to deal with. In order to make it easier to carry out these tasks, the room is now assigned to me. Some time ago, my lover came over and discussed it with her, and some time ago I simply moved in directly, and we are neighbors. ”

Yan An almost forgot that Gao Shenghan, a child nemesis in his thirties who was trying to have children, was a family man, and if it was inconvenient for him to move, his wife could do it for him.

Anyway, when I was in Pingjing before, I had heard that his father seemed to be a combat hero, and the plaque of "House of Glory" was hung all over the door, but Yan An, who didn't know enough about it, didn't know what kind of concept this was.

He answered, locked the door of the algorithm building, and threw the key to Gao Shenghan.

The two went home together, Yan An was suddenly shaken by a golden light in the corridor, raised his head, under the noon sun, there was a golden plaque hanging on the wall of the door opposite his house, about forty centimeters long and thirty centimeters high, in the middle of the plaque, is the crimson "glorious home" four big characters.

The plaque was hung on the wall of the door opposite him, and the light shone but not dazzling, giving people a sense of neutrality and peace. The words on it are written very boldly, and through those words, Yan An seems to be able to see the story behind the plaque.

Before Gao Shenghan knocked on the door, it was opened with a click, and a one-armed old man stood at the door wearing a military coat, "I saw you from afar on the balcony, I have been slacking off recently, and I don't even look like I am walking, like something." ”

He criticized Gao Shenghan harshly, turned his head to look at Yan An's face and showed a smile, the reprimand of Gao Shenghan did not affect Yan An at all, the old man nodded to Yan An in a kind tone, "This is a neighbor, right?" We are new to the city, and we may have a lot of trouble in the future, and we hope to have a lot of packages. ”

His voice is hearty, and his opening is a mixture of local dialect and Mandarin, but fortunately, they are all easy-to-understand dialects, and it is not difficult to understand what he means.

However, looking at his demeanor, the old man didn't seem to know what he was doing, let alone that Gao Shenghan's object of protection was him, and he completely regarded him as an ordinary neighbor.

"Dad, why are you here?" Gao Shenghan happily stepped forward to meet him.

To be honest, because he hadn't seen his father for a year, even if he returned to Pingjing to participate in the cave demon project, he hadn't gone to his father at all, so he didn't expect him to appear here to give himself such a big surprise.

"Take care of each other, take care of each other." Yan An nodded and said hello to him, and flashed into his house alone.

Because I was away from home for more than ten days, the power was cut off for safety, and the sweeping robot at home did not work, resulting in a thin layer of dust.

Cleaning is necessary, and it is also necessary to clean the environment of the home well, which can be regarded as a farewell to the old and welcome the new.

This is a large amount of work, Yan An is divided into several parts, and only deals with some of them every day.

After the clean-up work was completed, he ordered to deliver vegetables and fruits, after all, he couldn't eat instant noodles all the time in the next few days, quick-frozen products could be arranged, and he also needed to supplement some vitamins and nutrients.

He's not very good at cooking, and he's not interested in it in the past or now, but it's still okay to make a carrot, a baby green, or something.

Because the Chinese New Year is approaching, the dishes are scaryly expensive, and even the service fee for delivery is rising, Yan An finally spent 500 to get all the things he needs.

For the next few days, he stayed at home, and his days were relatively leisurely, allowing him to focus on learning quantum-resistant codes.

If this thing is directly retrieved by BT, it is based on Mingxing's cryptography environment to search for quantum-resistant ciphers. The results of that search are a bit too much for the current environment of the Emerald Dome.

Whereas, the algorithms used to crack codes in today's quantum computers are Shor's algorithm and Grover's algorithm. Needless to say, the former is used to solve the problem of large integer factorization, while the latter can reduce the length of the key by half, greatly increasing the probability of the attacker's successful attack.

Therefore, what he wants to search for is the "quantum-resistant code" that can avoid the threat of these two algorithms, and there are more than a dozen categories recorded in BT's database, of which all the items in the four categories of C, M, S, and L add up to nearly 100 items, although these quantum-resistant codes have been gradually eliminated in the long years, but they can still play a leading role on the blue dome.

Yan An picked and chose among the four existing encryption algorithms of Biqiongxing, and finally fell in love with the Geji encryption algorithm.

I have to say that there is a reason why the L-class algorithm can derive the fully homomorphic encryption algorithm that appears on the blue dome. Lattice is a mathematical construct defined as a linear combination of integer coefficients of a set of linearly independent non-zero vectors (called lattice bases).

Compared with other types of algorithms, the encryption algorithm based on this algorithm has three advantages: worst-case to average-case reduction, taking into account both public-key encryption and digital signature, and being able to build complex applications based on lattice cryptography. It is currently the most talked-about quantum-resistant cryptography, and the lattice-based algorithm is the most likely to stand out in NIST's screening, and no one knows when it will become the new generation of "RSA".
