“Enlist in the military!”
Myungsu-hyung continued.
“I don’t think there is a better solution than this. And after being discharged from the military, I need to make a concrete plan now to leave home and become independent.”
“Are there any specific plans?”
“Where to get a studio, how big a studio to get, whether to rent a house or a monthly rent, I plan these things meticulously and tell my mother, and at the end I put a wedge like this.”
“… ?”
“I want you to clean up the house you are living in now.”
“Is this our apartment?”
“right.”
“But do you really need to sell the apartment?”
Myungsoo hyung smiled at my question.
“It doesn’t matter if you sell your apartment or not. And after you’re discharged, whether you really want to be independent or not, it doesn’t really matter either.”
“It’s not important… I don’t know what you mean.”
“The important thing is to make your mother think about whether or not to organize the apartment.”
Myungsoo hyung smiled slightly and continued.
“If you think about it like that… Jung-ho, you will think that you are really grown up, and you will feel that your work as a mother is over.”
I nodded my head, and Myungsoo hyung smiled and said.
“There is a person I know who works in the Military Manpower Administration. If you want to go to the army quickly, just tell me. I will talk to you.”
“That’s… Is it really possible?”
“It can be a bit of a problem to slow it down, but it shouldn’t be difficult to pull it forward.”
After a while, Myungsoo hyung left for his company emphasizing the fact that he had accumulated five give and take so far, and I returned to Yunseong Soft’s office and sat down.
When I moved the mouse, the monitor’s screen turned on again, and I received an email with Leah Kim’s name on it.
＜Sorry! Totally disgusting! I saw a doppelganger yesterday!>
It feels like I can already hear In-cheol’s trembling voice in the email subject line.
My head was complicated with the thought of the military, but without realizing it, a smirk came out.

Jung Ho.
Remember the policeman who saved me when I was little?
Kim Jung-soo, the team leader, came to school a few times in middle school and bought us pizza.
I saw a Japanese person who looked just like that man yesterday.
I was really surprised!
Our cop guy was a little fat, wasn’t he?
Some belly fat too, right?
By the way, does this Japanese person do gym?
Your body is completely Arnold.
Our eyes met for a moment, then we immediately opened our eyes and opened our eyes.
Anyway, I think they both have the same face and the same height.
Judging by the fact that they’re wearing sweatpants, it seems like they live nearby, so next time we meet again, I’ll try talking to each other.
If they even have the same voice, you’re a real doppelganger.
eww—-! creeps!
ah! And check the attached file, and send me the zero value!
Please. Daughter and Daughter!
From Leah Kim.

It’s already the seventh.
In the past month, Incheol has sent RSA security certificates and requested the zero value needed to find the key D value.
I opened the security certificate file that Incheol sent.
But this… .
It doesn’t seem like an ordinary security certificate.
In RSA encryption, the value of N, the product of two large primes, is called the RSA coefficient or RSA modulus.

Naturally, the larger the value of N, the more difficult it is to crack the RSA encryption.
In other words, it means that the cryptographic system is more secure, but it is not possible to use a arbitrarily large number as the value of N.
This is because the operation time for locking and unlocking the password becomes longer and the speed of transmitting encrypted information becomes slower.
Therefore, the size of the N value used in RSA encryption tends to increase in proportion to the computing power of the computer.
For example, as of 2000, 512-bit size of N value used in commercial RSA encryption is standard, but after 2010, N value of 1024-bit size will be mainly used.
For reference, 512 bits yields approximately 150 decimal digits, and 1024 bits yields approximately 300 digits.

Now, the number of digits of the N value in the security certificate Incheol sent has exceeded 1200.
That is, it is a 4096-bit cipher.
In-cheol, this child… .
Are you trying to hack any military secret?
I started writing a reply to Incheol.
+ +
Mr. Kim Leah!
Have you checked the security certificate?
The size of the RSA coefficient N value is 4096 bits.
Did you know that in 4096 bits, the value of N has over 1200 digits?
under——!
You crazy child!
What the hell are you doing?
And I’m not doing this because I don’t want to tell you, and the N value corresponding to the zero values of the visa name I have now does not exceed 500 digits at most.
In order to solve the 1200-digit N value, you have to find the corresponding zero value separately, and you need a supercomputer to find it.
Why don’t you stop acting weird and come to Korea now?
Come join the army with me.
Jung Ho.

same time.
My own room in Bunkyo Ward, Tokyo, Japan.
In-cheol, who checked Jung-ho’s e-mail, grinned and muttered to himself.
“Ja-shik, the guy with the supercomputer on his head is terrifying… .”
In-cheol wrote a reply to Jeong-ho, and as soon as he pressed the send button on the email he wrote, the cell phone on the desk started to ring.
“Hello.”
-In, Incheol… is this right?
In-cheol, who recognized the other person’s voice, spoke with a pleasant voice.
“uh! Ji Eun-ah! me right I get along well?”
-yes. Nothing special here how are you doing too?
“then! Aside from getting a little tired of Japanese food now, well… I am doing fine.”
– Then why did you change your phone number again?
“ah… ! I dropped my phone in udon broth a few days ago.”
– Whoa! How can you destroy 3 phones in one month?
“haha–! I know! Is it because Japanese cellphones are slippery?”
-and… I want my mom to say thank you so much.
Unlike usual, Ji-eun spoke in a calm voice.
-My mother is crying like that… i saw it for the first time And the next day, my mom told me. It seems that the stuffy core that has been clogged up in my chest for 15 years is now gone… .
Incheol said with a bitter expression.
“I wanted to tell you the good news, but I’m sorry I couldn’t.”
– No, what are you sorry for? then… Are you coming to Korea now?
“I think it will be a little late to go back to Korea. I just started a new job.”
– New job?
“Yeah, what… I was looking for your father’s records and I found something interesting. However, this is not certain yet, so I will tell you about it when I go to Korea.”
-Yeah, even after work, come quickly. miss you so much.
“I miss you too. and… .”
Incheol hesitated for a moment before continuing.
“I plan to go to Osaka next Monday. To find the place where your father is buried. If I find it, I will take a picture and send it to you.”
After In-cheol’s words, the author didn’t say anything.
After the silence, the author’s voice was heard across the receiver.
-Perhaps… Dad’s grave… When you find it, can you tell my dad this?
“… .”
-I don’t have any memories of my father, but there is one thing that I do remember. … … .
When the author’s story was all over, Incheol opened his mouth with a slightly locked voice.
“OK got it. I will tell you.”
* * *
In just 5 minutes, Incheol’s reply came back.
In-cheol said that he knows my abilities, so it’s okay to be late, so I ask you to find the zero value and send it to me.
Actually, I was already checking the CJH algorithm code.
An algorithm that finds the non-obvious zero value of the Riemann zeta function using the graph technique.
The number of digits of the zero value required for Incheol exceeded 300, and since high accuracy of 50 digits after the decimal point was required, the code had to be rewritten from the method of allocating the variable value memory of the algorithm.
For reference, the non-name zero value required for Incheol exists in the vicinity of 10 to the 317th power.
The latest Pentium 3 CPU specifications are 32-bit 1.3GHz.
This means that a 32-bit simple operation can be repeated 1.3 billion times per second.
I looked at the new algorithm, and it will take about 30 seconds to get a single 317 digit non-name zero value.
In the expected interval of 10 to the 317th power, there are approximately 50 million non-name zero points, so the total time required for the calculation is 25 million minutes when 50 million times 0.5 minutes, and when converted into years, it is 47 years and 6 months. .
Simply put, it means impossible.
To inform In-cheol that it was impossible, I opened an internet browser, and the first email I sent from In-cheol caught my eye.
This is the email that Kim Jung-soo had seen a doppelganger.
Team leader Kim Jung-soo said that after we entered high school… .
To be precise, Incheol has been watching Incheol since he hacked into the education office.
Last time I met Team Leader Kim Jeong-soo, when I asked if my future had changed because of In-cheol and Eun-seong, he did not deny it.
Under the circumstances, the person In-cheol saw was not a doppelganger, but team leader Kim Jung-soo.
Reminding me of the fact that Team Leader Kim Jung-soo followed In-cheol to Japan, I changed my mind.
okay… Let’s do the calculation again.
If it takes 47 years and 6 months with one computer, it will take 6 months if there are 100 computers. If you calculate using 1000 computers at the same time, it takes 17 days.
And with 2000 computers available, it would take less than ten days.
A long time ago, I distributed the CJH algorithm to 28 domestic universities for free.

Now that it’s summer vacation, the computer rooms of these universities will be empty, and if you can use the computers there, wouldn’t it be possible to find the zero point value that Incheol needs?
I picked up the phone and called Professor Park Soo-soo, and to my explanation, Professor Park said that he would contact the professors at the school directly.
“Then I will ask you to pass on my contact information to the assistant in charge of the computer room at the school.”
– Yeah, don’t say it like that.
“thank you so much.”
– Thank you. On this occasion, I also contact my fellow professors and ask for their regards, well. Heh heh heh—!
“Professor, have you ever applied for a family reunion?”
– Well, I did. By the way… .
Professor Park’s voice followed with a short sigh.
-The person I’m looking for is not my immediate family, so they said it would be very difficult.
next day.
I received a call from the computer labs of 23 universities, and I sent the files that compiled the new CJH algorithm to the people in charge of the computer labs at each university.
The executable file contains the algorithm to send the found zero value to my personal server along with calculating the zero value for each section of the Riemann Zeta function.
Three days later, it’s Sunday.
The zero value needed to break the N value of the security certificate sent by Incheol came into the server, and I sent the found zero value to Incheol.
