79. One Neon
Yoon Sung Soft’s main business item is Michael Security, and its performance was so great that the word “main business” was insignificant.
Michael Security’s business target is a public institution or corporation that operates a server for the website, but the current customers were the Seoul Metropolitan Police Agency and two small IT companies.
The Seoul Metropolitan Police Agency delivered Michael Security through a so-called tying-and-sell method when signing a contract with the missing child search program, and the other two IT companies were small ventures run by Yoon Seok-yi’s acquaintances.
In other words, the proportion of Michael Security in Yunseong Soft’s total sales is negligible, and most of the operating profit was actually made through V-Stop.
This was not the direction of the business that neither I nor Yun Seok-hyung wanted.
However, commercialization of Michael Security was not as easy as expected.
Currently, in the Internet security field, two software markets are divided.
One was a package called ＜Comdoubidae> made by a company called ‘Hacker Factory’, and the other was a program called ＜ShieldSafe> developed by a foreign company called ‘Shield.com’.
When I said that I would sell Michael Security to a server company, Yoon Seok-yi asked.
“How are you going to sell Michael Security there?”
“In the meantime, I did some research on the security packages of our competitor, ＜Comdou Guard> and ＜Shield Safe>.”
“what? Aren’t you studying for the SAT?”
At Yoon Seok-hyung’s words, I smiled and continued what I was saying.
“If you are a server company of a certain size, you will definitely be using either ＜Comdougari> or ＜Shield Safe>. I’m going to meet with the server company and offer to find out the weaknesses of the security package they’re using.”
Simply put, it means that I will become a white hacker and break through the security programs used by server companies.
At my words, Yoon Seok-yi hyung made a confused expression, while In-cheol asked me with his eyes twinkling.
“Are you looking for weaknesses? How are you going to hack it?”
It was a year ago.
After returning to the United States, the major’s sister was able to obtain a small fund based on the research idea I had proposed.
It is an ambitious project to prove the Riemann hypothesis, and I convert the non-annual zeros of the 5 million Riemann zeta functions I found at that time into multidimensional coordinates to create a continuous manifold, It was the hypothesis of our study that we could find associations with infinite sets.
However, the research fell into a labyrinth again.
The tentative conclusion we made at that time was that the number of non-anonymous zeros I was looking for, that is, 5 million non-anonymous zeros, was not enough.

Naturally, the direction of research has changed.
Searching for more visa name zeros.
The computing power of supercomputers is truly amazing.
It took me three years to find 5 million non-name zeros using a personal computer, but it took only four days to find 5 million non-name zeros using a supercomputer.

Not only this.
The zero-point values I found have an accuracy of 10 decimal places, and the zero-point values found using a supercomputer showed a high accuracy that could not even be compared to 59 decimal places.
In this way, we are using a supercomputer to find the non-name zero value of the Riemann zeta function over the past 9 months.
The number of zero values found so far is close to 130 million, and we aim to find 200 million zero values within this year.
Lucas and I, who are students of the major’s sister, have been experimenting with these zero values, and one of them is finding a conversion function for zero values.
The domain of the transformation function we are looking for consists of non-consecutive elements, and the range of this function, that is, the set of function values, consists of continuous elements.
To be more specific, the domain of the transform function is the set of 120 million zero values we have found so far, and the range of the transform function is the line or plane that composes a continuous manifold.
To put it simply, I was trying to find the regularity of the non-name zero value of the Riemann zeta function, but this was not an easy task.
I sent the conversion function I found after months of groaning to my major sister and Lucas, and they answered No.
Actually, I was expecting my sister’s negative answer to some extent, because the conversion function I found showed significant results for about 80% of the zero value.

Nevertheless, there is a reason why I introduced the conversion function I made to the major older sister.
This is because the conversion function value showed more significant results as the zero value increased.
For example, substituting a relatively small zero value between 0 and 10000 into a conversion function will result in completely bogus results.
However, for 10-digit zero values, i.e., billions of zero values, more than 60% of zero values showed less significant conversion results, and for 30-digit zero values, a clear rule was found in 80% of the converted function values.
And in the case of the 57-digit zero values that are currently being calculated by a supercomputer, the conversion success rate exceeded a whopping 92%.
This means that the transformation function works well for large zero values.
If the Riemann hypothesis had been a problem in the field of engineering, the transformation function I found would have been recognized as a pretty good research result to explain the regularity of the zero value of the Riemann zeta function.
Unfortunately, in mathematics, research results that are not 100% mean nothing.
Moreover, according to the major sister’s argument, the reason for the high conversion success rate for a large zero value is that the error tolerance increases as the zero value increases.
For example, assuming that the error range, which is the standard for conversion success, is 0.1%, when the zero value is 10, the error range of the function value is very small as 0.01.
However, when the zero value becomes 100000, it was the same principle as 100 even with the same standard of error range.
It wasn’t that there was nothing to refute the major sister’s argument, but I kept my mouth shut.
This is because it is the proof of mathematics that collapses even if there is only one counterexample.
This was three months ago.
While I was forgetting about this conversion function, I saw a malicious article by So-Jeong reporter a few days ago, and it was this conversion function that I looked for again to forget my upset heart.
I made the inverse function of the transform function, and substituted some numbers into the inverse function, and found that the result was similar to the pattern seen by Euler’s pi function or Euler’s totient function.
Euler’s pi function is a function that tells the number of numbers from 1 to N that are disjoint from N for a given positive integer N.
For example, if N is 15, the numbers less than 15 that are prime with 15 are:
1, 2, 4, 7, 8, 11, 13, 14.
There are 8 numbers like this, and the value of the Euler pi function for 15 is 8.
Here, if N is a number formed by the product of two prime numbers, an interesting mathematical formula holds.
For example, 15 is a number made from the product of two prime numbers, 3 and 5.
Here, 3 -1 = 2, and 5 -1 = 4.
And multiplying 2 by 4 gives 8.
That is, the value of the Euler pi function comes out.
The algorithm developed based on these mathematical characteristics is the RSA encryption system, and many security programs are built based on the RSA encryption system.
In particular, ＜ShieldSafe> of Shield.com was created based on RSA. If you open the digital certificate file issued by ＜ShieldSafe>, you can directly check the N value and key information used in the RSA encryption system. have.
Incheol asked how he would hack.
My answer to that question is this:
‘I’m going to break through the RSA cryptosystem.’
But instead of this answer, I came up with a vague answer.
“I just discovered a new method, and I want to check it out for ＜Shield Safe>.”
In-cheol nodded silently at my words, while Yoon-seok-hyung shook his head and said.
“I studied ＜Shield Safe> by myself, but the security program is really meticulously made, so it doesn’t seem like there are any gaps?”
At Yoon Seok-yi hyung’s words, In-cheol muttered a pizza.
“It’s not that there aren’t any gaps.”
Yoon Seok-yi hyung gave a surprised expression, and In-cheol swallowed the pizza in his mouth and continued.
“It varies from server to server, but I think ＜Shield Safe> usually detects malicious code late. There seems to be a bit of an open port problem.”
“How did you find out about that?”
Yoon-seok hyung’s question was answered by In-cheol as if he didn’t care.
“The boss couldn’t come to the office, so I was doing this and that at home by myself.”
“men and horses! What would you do if you didn’t study and are doing something like that?”
“Sir, aren’t you really doing too much?”
“What? What am I?”
Incheol said with a look of dissatisfaction.
“You promised that if you get over 300 points in the mock exam, you’ll get a job at Yunseong Soft, but later you raised it to 350, and now you’ve raised it to 370!”
“No, that means that I want you to prepare well for the entrance exam… .”
Eun-seong cut off Yun-seok-yi hyung’s words.
“brother! Have you ever broken a promise you made with an employee? Is that on purpose?”
“Huh? Why are you like that?”
“Hyung, this is in a high school canon textbook, do you know what the first principle of business is?”
“The first principle of management?”
“It’s trust between management and employees.”
Is it because Eunseong’s school and our school’s political economy textbooks are different?
Anyway, there is no first principle of management in the textbooks we use.
Eunseong continued with a calm expression.
“If the employees do not trust the words of the management, the company will not be able to respond flexibly in a crisis situation. And vice versa. They said that when management does not trust the abilities of its employees, the company is missing out on opportunities to grow.”
At Eun-seong’s words, Yoon-seok-yi hyung said with a questionable expression.
“really? Is there something like that in a high school textbook?”
“Our homeroom teacher is Jeonggyeong, are you saying that our teacher is wrong now?”
“haha! I’m not saying that… .”
Yoon Seok-yi hyung continued talking to In-cheol.
“In-cheol, do you understand what I am saying? It’s not that I broke my promise on purpose… .”
Eun-seong cut off Yun-seok-hyung’s words again and said.
“If hyung says that, of course In-cheol says it’s okay. It’s your boss.”
“haha! is it? But Eunseong-ah, why are you on In-cheol’s side today?”
“In-cheol and Jung-ho… .”
Eun-seong put her arms on In-cheol’s shoulders and me and In-cheol’s shoulders, and continued talking.
“You are my lifelong friend.”
Eunseong smiled and continued talking.
“brother! I’ll take care of the traffic today. Let Incheol go to work from tomorrow. Instead, if you don’t get a score of 370 on the next mock test, you’ll be out of the office.”
“Eunseong-ah, that’s a little… .”
“a! It would be nice if In-cheol can help you now too. Yesterday I was working from home until dawn.”
“president! I am good.”
At In-cheol’s loud words, Yun-seok-hyung reluctantly nodded his head.
This time I said to Eunseong.
“Eunseong-ah, how can I get out of traffic too? yes?”
“ah… ! okay? So, how many points would you make on the mock test?”
“I have 375 points.”
In response to my answer, Eunseong covered her mouth with her hand and spoke in a low voice.
“Hey, you said you managed to pull-up 340 points in the last mock test? Isn’t 375 points too high?”
I said with a smirk.
“it’s okay. I have to get 375 this time anyway.”
“Are you supposed to get 375 right anyway? What does that mean?”
I said with a short sigh.
“Anyway, what! There is such a thing.”
In the end, thanks to Eunseong’s traffic arrangement, I was able to attend a meeting with a server company.

Northwest High School Office.
At Jeong-ho’s suggestion to make a bet,
Teacher Lee Hae-bang, the homeroom teacher, said with a bewildered expression.
“What, what? No, what about this guy?”
After a while, Professor Lee Hae-bang continued to speak with a smirk.
“What? Have you ever seen such a brazen bastard? okay? What would you like to bet on?”
“If you score over 350 in this mock test, please take it out of that night self-study.”
“a! What is a trivial 350? yes?”
“then… … 360 points… huh?”
“Huh? If you want to provoke a teacher, you have to do it right. Can you get 360 points? Let’s go to 380.”
At the words of the homeroom teacher, this time Jung-ho turned into a bewildered expression.
It wasn’t that I wasn’t confident, but a score of 380 is a score that ranks in the national rankings.
“why? Are you not sure? If you don’t have confidence, why don’t you leave early today as nothing?”
“380 is too much, let’s make it 375.”
“375 points, ok!”
“Then, if you get over 375 points, do you really miss out on self-study at night?”
“Of course! instead!”
“… ?”
“Instead, if you don’t get over 375 points, Jung-ho, you’ll change your seat.”
“Are you changing seats?”
“I’m going to have Minhyuk, the handsomest in my class, sit next to Yeong-mi.”
“yes?!”
