The Economics of Prophecy

"The most important thing is done. So, how many types of Imperial letters are there?

"Were you even doing that without knowing it? My lord, it's still ridiculous."

Ten is a civilian angry at the words of a younger girl.

"Answer him, Kyle."

"... thirty-four kinds."

"All of these documents are made up of thirty different letters. Probably, but we're pulling out some vowels."

As you can see if you recall the abbreviation in English, even if you pull out the vowel, you can almost understand the meaning of the word.

"So what's the average number of characters in an imperial word?

"What does that mean?... shouldn't be so different from the kingdom"

"Now let's say 90 percent goes into the same six plus or minus two characters as the kingdom. Then assuming you pull the vowel, it is assumed that this symbol, “ “ Lyuda ”, which appears on average every four characters, serves as a space. Likewise, if the average number of words in an empire's text is divided, we can deduce the symbols that represent the delimitation of sentences, periods in the kingdom."

".................. what are you talking about"

Meer explained that he hasn't returned entirely from the world of numbers. Civilians are haunted. Now, two symbols are figured out.

"By the way, this sentence isn't one, it's substituting letters by at least three cryptographic tables"

Meer divided a sufficient number of letters into three bundles of remaining burnt documents. I can recognize patterns just by looking at them. Meer is special, but when she does this, I can somehow tell the three kinds of distinctions.

Perhaps the Chancellor and the Civilian are able to recognize something different. It is proof of this that a civilian nearly opened his mouth.... The Chancellor's gaze has become more and more demanding.

"What is the rationale for the existence of three types of cryptographic tables?

The Chancellor asked.

"The frequency of letters in the right sentence group is the order of" Silda "," Ω "Olm" and "Garma". The group in the middle is in the order of α "Afra", η "Zechi" and η "Ellon". And on the left is the order of Ä…. In other words, the text on the right and the alpha on the left in the middle are the same letters if decrypted. "

It's easy to understand when you think in English. Alphabetic 27 characters are not used with the same frequency. You know there are a lot of i and e. The frequency is naturally inherited even if encrypted. If a sentence has enough characters, the patterns of the most frequent characters are almost together, regardless of the content. Especially the top few characters.

Let's say you used three cryptographic tables to encrypt three short English novels. In the three types of sentences, the most frequent characters become seemingly different. But that percentage will be about the same.

Assuming that the percentages of the top three most frequent characters in a document are about the same, and that the types of characters differ, it can be analogized that there are multiple cryptographic tables.

Perhaps what Meer just saw earlier determined was the pattern of the most frequent characters in that sentence. Of course, only a special talented person like Meer can do that at a glance, but with paper and a pen, it's a possible artist for anyone. You just have to count it.

Even if some vowels are removed, you can calculate them assuming there are a few.

"How often do letters appear in Empire texts? You keep as many ordinary texts written in Imperial language as you want."

Meer said. Civilian got up in a gruesome move.

"This sentence probably replaces α with α and Ω with η. Later, if you consider the array of characters that often appear in the word, you should know the characters replaced by the bug eating procedure. Every letter you discern increases the difficulty of guessing, but at the same time, fewer candidates and more peripheral information make the rest of the discernment easier. acceleratively."

Next up is a pattern of letters in line. For example, in English, the lines of TH and WH often appear. A past form would have ed behind the word. By the way, even if the same vowels are used in English, the same consonants are not the first in a row. I guess that's what empire ciphers mean when they're out of vowels.

Of course, it is possible that the ciphertext omits the current situation. In that case, the character frequency of the text assuming it may be recalculated.

World War II, German and Japanese ciphers were solved by mathematicians. Turing, the ancestor of computer theory, is famous for his achievements.

Neither of them is a complicated process that goes beyond the cryptography of this empire. It's not just a replacement, it's trying to erase patterns using date, time and random numbers.

But even primitive computers found the pattern.

It is also a fundamental principle of how meaning can arise, so we cannot escape it. Turing didn't solve the cipher simply because he's good at mathematics, the very concept of computation is behind it.

By the way, it's basically the same thing our brains do to words.

"From the perspective of pattern manipulation, this is extremely simple."

Meer is looking down at interstate secrecy with a quiet eye. The two across the street are no longer in the face of being shown something creepy. Tastes bad.

"I think you understand. This is a cryptographic” all ”solution based on the replacement of characters."

Again, the two in front of me are trying to get to a fucked up understanding. What Meer did is the same thing that killed all the ordinary ciphers in this world.

It's a total crisis of preservation. The lives of two civilians are the lights in front of the wind.

"How do you judge?

"............ The Kingdom's cryptography needs to be addressed fully. There is no point in changing the cryptographic table for those who know this principle"

The civilian dropped his shoulder disappointingly. The Chancellor's eyes are getting even tougher. Look, I'm staring at you more than I thought I was an imperial spy.

"Oh, by the way, the Knights are working on that."

So I supplemented. If you erase the two civilians in front of you, you will be able to monopolize the basic principles of cryptography.

"Later, read the contents of the cipher there before you tell me. Because neither of us can read the words of the Empire. However, if you don't teach me properly, I can't judge your involvement with horse dragons here."

I pressed my guard. It is only there to manage the content, satisfying the superior's faculty and desire to manage it. Civilian mirrors, the secrets of preservation. Here it is.

"Both Fulsey and the Grand Duke are hiding from even the prince."

I arranged all the preservation I had prepared, but the Chancellor's eyes aren't laughing at all. I'm a maintenance professional. That's all I cared about, but it doesn't really work.

"What do you want?"

The Chancellor said on top of each other.

I haven't had this kind of interaction in a long time. Now that I think about it, Fulsey and Noel were obsessed with knowledge and loose, and Euphilia and Craig were sweet with that.

"... there are two, if you insist. It's pretty big, but you still want to hear it?

Say it.

"One is the mechanism for organizing the observation of demonic pulse fluctuations. We want to build a finer observation system as well as a red forest between East and West. It's the realm of demons, near the middle of the Great River."

"Hmm?"

So how do you overthrow the state, the prime minister sees me with a face like that? Because the other way around.

"Eh, that's how you get the data, you combine the frequency of the crystal signals. With the data stacked, we may be able to estimate the scale, timing and direction of the disaster without the witch princess."

"Well, are you going to tell the princess that I'm just a kid who thought about it"

said the Chancellor.

"Duh, how can we talk about that? Isn't it a natural demand for national security to create a system that relies as little as possible on it than a human being with the qualities of a witch princess is rare? No, that's how much you can tell."

For some reason, I sweated cold and stood up. Meer stepped on my feet under my desk. Shit. Too much.

"Take a seat at the Chancellery."

"I'm a merchant all my life."

I said. What a perfect palace service.

"..................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

said the Chancellor. I don't know what that means, but what did you put the fold on?

"What's the second?

"Oh, yes, uh, another source left by the Empire, the interview with His Royal Highness Leezaberto."

It's a planned request. I don't go first by taking a story from Craig or Euphilia to the First Knights, who are holding the princess back.

The Chancellor and the First Knights aren't friendly either, but it should be a lot better.

But it's been tough ever since. Unlike the two previous ones, this is the hardest information gathering for me.

"When it comes to creating a new code, it's your girl's."

The Chancellor spoke to us when he tried to take his seat off. I pulled Meer back later. When you breathe heavily, you face the old man.

"And yet, Chancellor, there are things that civilians can and cannot do as well"

I didn't say anything strange about the Prime Minister's position, but I have this position here. It doesn't matter who you are or what you are or what you have to fight for if you step over it.

Even civilians have the right to live in peace and serenity. I'm just saying that no one is guaranteed that such a right would be civilian or aristocratic.

And to do so, I need that purple-haired princess to help me, too.
