C1361 Top secret of the CIA

codebook! It was one of the core secrets of the Chinese CIA. With it, France would be able to easily eavesdrop on all the Chinese military intelligence and successfully translate it.

The early telegraphic technique were very primitive. This kind of completely open source electrical signal was actually very easy to listen in on. Humans actually borrow the speed of electricity and design a simple closed system to complete the transmission of information.

Beijing, who was thousands of miles away, sent an electric signal to the telegraph network and instantly, the telegraph of Ryukyu received the signal and recorded it down. At this time, if there was anyone on duty in front of the telegraph of Ryukyu, he would start to record these codes with different lengths.

This was the most primitive method of manpower. In the future, when there was a further step in technology, there would be an automatic transceiver. The receiver would be able to record electrical signals from afar even without 24 hours of guarding.

This pattern was fast, but there was a big problem with its efficiency. That was, the openness of the telegraph network s posed a huge threat to the secrecy process.

In reality, there was no way a telegraph line could only have two connections, Beijing and Ryukyu, what about a half-way Deer Island? Where's Tianjin? And the Tanggu? What about Shanghai Jiangning? There were also countless transceivers waiting for these signals.

In other words, when the signal was generated in Beijing, all the nodes in the entire telegraph network chain would be able to receive this signal, unless you cut it off physically.

As for the civilian and commercial telegrams that didn't require a high level of secrecy, this problem could be solved by performing the code at the beginning of the electric signal. Every region, every telegraph had their own code.

However, the problem of telegraph messages being used for military purposes was much more serious. The strong ones all had their own intelligence personnel s, they would monitor the electrical signals sent by important targets 24 hours a day, and would definitely not miss a single one.

As soon as the military telegram from Beijing was sent out, there would be more than a dozen spy interfaces on the line, recording the varying rhythms of these electrical signals.

The civil code book was open to all, and everyone could translate the rhythmic beeping sounds of the translations into the human language.

This kind of openness could not be tolerated by the military or intelligence personnel. In order to keep the existence of the codebook s that were highly confidential, every country, even every system would develop their own codebook.

Beep, beep... Beep... What did two short and one long signal rhythm represent? Russia had its own secrets, Britain had its own English translator, France had its own comparison table, and the Chinese had their own codebook.

The rhythm of the signal was completely different for codebook from different countries. This caused the other party to have difficulty deciphering it.

Overall, the more complex and scientific the codebook's plan was, the more confidential it would be. According to the statistics of the CIA, the current level of coding in Sha Russia was the lowest. They just marked different Russian characters with different electrical signals.

To outsiders, this kind of telegraph was obviously unintelligible, but to those elite warriors who had been influenced by Xiao Letian's new intelligence, this kind of secrecy was extremely primitive and lagging behind.

There are a total of 33 letters in the Russian alphabet, and at first we did not understand what each electrical signal represented, but don't forget that the Chinese intelligence officer knew how to eliminate them.

First, they allowed the spies to get close to some low-level telegrams by hand. If they could decipher a letter, they would have to decipher one letter at a time. As the number of letters they deciphered increased, the telegrams would gradually reveal themselves.

After almost two years of settling down, the CIA had already grasped the three sets of code compilation forms for Sha Russia. The embassy in Sha Russia in Beijing was now transparent to the Chinese race, which was the key factor for why Xiao Letian was able to grasp all the information in the Expeditionary forces.

Before this, Molière did not believe that Chinese people could be that smart, but today, when he saw the codebook written by Chinese people, this China Tong cried.

He sobbed like a child, and the three men in the underground fortifications were stupefied. They had no idea what their boss was up to.

"I was wrong, we were wrong! We underestimated the enemy time and time again, but the result was that we were played by the Chinese again and again! They are not idiots, and they are not idiots either. They are a group of geniuses! "

"Now I finally understand why we lost. Just based on the difference in intelligence, it's clear that we will lose for sure!"

"I have the Chinese telegraph codebook, they are a bunch of geniuses. Their codes are not written in Chinese characters, but in Chinese characters. Who do you think can understand Chinese characters?"

"Not only that, they even chose the second layer. The first layer uses numbers, and each number represents a different book's coordinates!"

"Look at this book, it has already been folded onto the page of the Four Books. What does this mean? This means that today's secret messages will have to be found in the four books for an answer! "

"A number is the number of pages and the number of words per page! Sixth word on the third page... First word on page 11... Fifteenth word on page eight... "We have to find them and compile them to form one sentence!"

The surrounding intelligence officer were also dumbfounded "Four Books? What book is this? Four books? But there are no four books here, where are the books? "

"Wuwuwu …" Molière collapsed. This is the cleverness of the Chinese people, he knows that we do not understand Chinese culture, he bullies this, four books is not four books! It's a book, a book that Chinese scholars have to read! "

"Of course there isn't this book here, because this kind of book is a classic that all primary school students in China have to memorize. They don't have to memorize it to hit their palms. The real codebook is in the hearts of the Chinese people …"

"Look, today is the fourth book, tomorrow is the Five Classics …" What is this? Sister-in-law? There were also thousands of words … "Wait, I just thought of another problem …"

Molière slapped his forehead. I forgot the version! Different books have different editions, that is to say, their editions are different, and the order of the characters on each page is also different! If we don't know what version of the four books the Chinese use, then we still can't find the final answer! "

"Damn it!" How do the heads of these Chinese people grow? Why so smart? Why didn't we think of it? "

Molière had sunk into a deep state of inferiority. Actually, he couldn't be blamed, the humans had only just started using telegraphic technique on a large scale, and even the Undersea telegraph network that connected to the entire world had not been built yet. The teleportation system's coverage rate was very, very low.

This was a completely new technology. Currently, only the governments and the military had the ability to play with it. It was not widespread at all. Emerging things must take time to emerge and develop, and countries value them differently.

Xiao Letian was bullying others, using the password compiled during the second battle of the later generations to oppress intelligence officer, which was equivalent to a 20 year old great guy bullying a kindergarten's primary school student.

First, he had to put the technology aside. Ideas determined everything. A mature idea was more than enough for him to bully others.
