Butcher Demon-Chapter 183
Chapter 183
The quiet room was interrupted by a clanking sound.๐๐ณ๐ฆe๐e๐ฏn๐ผัต๐l.๐๐๐
I looked and saw Niblo and Diamond flipped over on the coffee table in front of the sofa. There was coffee spilled on the floor.
โWhat are you doing, you two?โ
โI think Yakumo made them drink coffee and then they went like that.โ
Natsuki told me.
For now, I went to the sofa and rescued the two creatures. They didnโt seem to be dead, but they seemed to be unable to find their footing. They were both like newborn babies. I wonder if coffee is as dangerous for spiders as it is for cats to eat leeks.
โdrink, promotion, celebration, too much โ
So they say.
At that moment, I suddenly saw the screen of Yakumoโs laptop.
It was a message board. The only post on the board said, โThe snow will stop, but it will soon come back harder.โ
โSo the snow will stopโฆโฆโฆโ
I can look out my window and see that itโs midnight now, but itโs still pouring down. But if Yakumo says otherwise, it must be so. Yakumoโs prediction is dead on.
Then Abigail walked up to me and looked at the screen. Her expression seemed to have lost some of its tension.
โHeโs our Nostradamus.โ
When I introduced Yakumo, Abigail seemed to notice his post and muttered, โAh, so this is himโฆโฆ.โ
โOh, by the way, did Gevaudan write that post?โ
โI had Yakumo write it on my behalf. He is the original prophet-kun, so there was an air to it, wasnโt there? And heโs pretty much right. You see, in the message to Abigail, there was a sentence saying that the wise men of the forest would be waiting for us. When I arrived at the church, there was a rare owl. You hit the mark again, Yakumo.โ
I rubbed Yakumoโs hair.
โHee~โ
Abigail looked at him admiringly.
Right after, Natsuki sat down next to Yakumo.
โAfter seeing onee-sanโs post, I didnโt know what it meant, but soon after, Yakumo searched for a place called Valhalla. It was also Yakumo who unlocked the credit card.โ
โYes. This boy is very capable. We canโt have a conversation, but it was Yakumo who found Abigailโs posts and told me about it.โ
โHee~?โ
As I said this. There was a very brief moment that I think I saw โ?โ on Abigailโs head, floating in the air.
โThis is something I donโt understand, but apparently Yakumo can decipher trip. So Abigailโs key came up as โGevaudanโ, the same as my name. He noticed it right away.โ
โโฆโฆ?โ
This time, Abigail had a noticeable โ?โ on her head.
โYou typed in the key and searched for the trip that came up, right?โ
โ?โ
It was my turn to tilt my head.
โHmmm? No, Yakumo found Abigailโs post, and then when I typed in the key you gave me, I found that it was the same one.โ
โIsnโt it the other way around?โ
โThe other way?โ
Abigail and I both had a โ?โ on our heads. floating in the air.
No This isnโt gonna work. This was a conversation between an analog and a digital person.
Maybe Natsuki can explain it.
โNatsuki, we checked the trip after Yakumo found it, right?โ
โYeah. After Yakumo found it, I made sure that the key gave the same trip character. Until then, Yakumo didnโt even know about the note that Jebotan had.โ
โโฆโฆ you are saying that Yakumo-kun can decipher the key from the trip?โ๏ฝ๐ณe๐w๐ฒ๐๐ฏ๐จฮฝe๐.c๏ฝ๐ถ
โAs I said,โ Natsuki continues, her hands on her hips.
โJust like Jebotan said earlier. Yakumo can read trip.โ
โโฆโฆ.. yes???โ
over Abigailโs head are โ?โ floating in large numbers. Itโs a wonderfully stupid face. I rarely see this kind of expression on her face. Iโll have to burn it into my memory. Polaroid โฆโฆ Polaroid โฆโฆ.
โHow can you possibly read it? The trip is a One-way function.โ
โWhatโs that?โ
I asked, and Abigailโs voice got a little raspy and fast.
โIt means that a trip can be easily generated by the key, but the opposite cannot be done. Itโs infeasible. Itโs practically impossible to know the original trip key from the trip. Thatโs why this is an anti-spoofing measure. If you can get it, you can impersonate whoever you want on the board.โ
Natsuki quickly responds, โYakumo can read it.โ
โThatโ s impossible.โ
โโฆโฆ Iโm not lying!โ
With a sullen scowl, She glared at Abigail.
โSo โฆ. what about this?โ
Abigail pointed to the trip on the screen.
โYakumo, try this trip out.โ
At Natsukiโs prompting, Yakumo typed in a few words.
The same trip was added to the post.
โSee?โ
Natsuki snorted smugly.
โEhhh โฆโฆ what the meaning of this ????โ
But this only deepened Abigailโs confusion.
They went through the same thing over and over again after that, but the result was the same.
It was demonstrated that the Yakumo could reverse calculate the original key from the trip.
In other words, we can impersonate anyone we want. Heaven has given a golden rod to the keyboard Warrior, and he could even cripple F-Channel with this. The tales of Yakumoโs legendary keyboard Warrior are just around the corner.
Abigail turns silent.
I look over and see that she is completely frozen. Her eyelids are wide open and she seems to have stopped breathing. Iโm starting to worry that sheโs having a seizure.
โWhatโs wrong? Are you okay?โ
When I asked her to confirm that she was alive, she looked as if she had seen a cockroach slip under the covers, a combination of surprise and horror on her face, and grumbled, โWhat the hell โฆโฆ. something like this isโฆ..โ
โThe one-way function is the foundation for all modern cryptography, Almost all computers are designed to be secure by taking advantage of the fact that one-way functions cannot be solved in reverse.โ
โHmm?โ
โJust now, this boy could even reverse engineer the tokens of the one-time password. In an instant.โ
โIs it amazing?โ
โItโs amazing โฆโฆ this is usually only a brute force analysis can solve โฆโฆ If Yakumo-kun can solve not only the trips on this board but also any one-way function in reverseโฆโฆโฆ.โ
Abigail cut off her words there.
โItโs not just spoofing in the message boards. Itโs possible to break any encryption.โ
Abigail looks back at me.
โThis kid is a prodigy. Thereโs no other logical explanation.โ
So it was like, His mind is not in the right place.
So, I shared the knowledge I had acquired over the past week.
โI think Yakumo has savant syndrome. I wanted to talk to Yakumo, so I did some research. Here, take a look.โ
I showed Abigail Yakumoโs notebook.
โIsnโt he amazingly good? They say savant syndrome is a peculiar trait found in some people with autism, that they have a little difficulty in everyday life like Yakumo, but they also have some outstanding talent.โ
Abigail shook her head helplessly at my attempt at unveiling my own theory.
โThis is on the level of godlike power. Itโs not a savant, or a gift, or any of that mundane stuff.โ
mundane โฆโฆ.
โBut, isnโt there a bit of a connection?โ
โItโs just not on the same level as savant syndrome. Heโs like a living Nondeterministic Turing machine. Donโt tell me heโs really a prophet?โ
You are using an analogy that I donโt quite understand. She doesnโt seem to have the time to pay attention to me. Iโm a little hurt that I went to the trouble of researching this. Iโm disappointed.
โโฆโฆ Jebotan, is she praising Yakumo?โ
โโฆโฆ maybe โฆโฆโ
While Natsuki and I were having our secret conversation, Abigail walked around to the front of Yakumo, who was sitting on the couch, kneeling down and making eye contact with him.
