Code book! It is one of the core secrets of the Chinese CIA. With this thing, France can easily eavesdrop on all the Chinese military intelligence and successfully translate it.
Early telegraph technology was very primitive, and this completely open source electrical signal was actually very easy to monitor. Human beings actually borrow the speed of electricity and then design a simple closed system to complete the transmission of information.
Thousands of miles away, Beijing sends an electrical signal to the telegraph network, and the Ryukyu telegraph machine can receive the signal and record it in an instant. At this time, if there is someone on duty in front of the Ryukyu telegraph machine, then he will start to record these different lengths. password.
This is the most primitive artificial method. When technology advances further in the future, there will be automatic sending and receiving devices. The recipient does not need to stay around 24 hours a day and can also record electrical signals from distant places.
This model is fast and efficient, but there is a big problem, that is, the openness of the telegraph network creates great concerns about confidentiality.
In actual circumstances, a telegraph line cannot have only two interfaces, Beijing and Ryukyu. What about Kagoshima halfway? What about Tianjin? What about Tanggu? What about Shanghai Jiangning? There are also countless transceivers in these places waiting for these electrical signals.
That is to say, when Beijing generates a signal, all nodes on the entire telegraph network can actually receive the signal, unless you physically cut it off.
For civil and commercial telegraphs with low confidentiality requirements, this problem can be solved by encoding the beginning of the telegraph signal. Each region and each telegraph machine has its own encoding. After a telegram appears, people only need to If you see that the code is not yours, you can automatically ignore it and skip over.
However, the problem of telegraphs for military purposes is much more serious. The great powers have their own intelligence personnel. They will monitor the telegraph signals sent by some important targets 24 hours a day and will never miss any of them.
Beijing's military telegram may have just been sent out, and there will be more than a dozen spies' interfaces on this line recording the rhythm of these electrical signals of varying lengths.
The civilian codebook is open, and everyone can translate these rhythmic signal tones according to the codebook, and then translate them into sentences of human language.
This kind of openness cannot be tolerated by the military and intelligence workers. In order to maintain confidentiality, highly confidential codebooks have emerged. Each country and even each system will develop its own codebook.
What character does the signal rhythm of Didi...Didi...two short and one long represent? Tsarist Russia has the secrets of Tsarist Russia, Britain has British translators, France has its own comparison table, and the Chinese also have their own code books.
The exact same signal rhythm has completely different meanings in the codebooks of different countries, which makes it difficult for the other party to crack it.
In general, the more complex and scientific the codebook is, the higher the degree of confidentiality. According to CIA statistics, Tsarist Russia currently has the lowest encryption level. They just mark different Russian letters with different electrical signals.
For laymen, this kind of telegram is of course incomprehensible, but for those Chinese elites who have been influenced by Xiao Letian's new intelligence thinking, this kind of confidentiality measure is obviously primitive and backward.
There are a total of 33 Russian letters. At first we really couldn't figure out what letters each electrical signal represented, but don't forget that Chinese intelligence officers know how to eliminate them.
They first asked the spies to manually approach some very low-level telegrams. If they could decipher a letter, it would be one. Just like this, little by little, as more and more letters were deciphered, the true identity of those telegrams would gradually be revealed. .
After nearly two years of accumulation, the CIA has now mastered three sets of Tsarist Russian code compilation tables. The Tsarist Russian Embassy in Beijing is now transparent to the Chinese. This is the key factor for Xiao Letian to clearly grasp all the intelligence of the expeditionary force.
In the past, Molière did not believe that the Chinese could be so smart, but today when he saw the code book written by the Chinese, the China expert cried.
He hugged his head and cried like a child. The three subordinates in the underground fortification were all dumbfounded. They didn't know why the boss was so crazy.
"I was wrong, we were all wrong! We underestimated the enemy time and time again, and ended up being played by the Chinese again and again! They are not fools, they are not idiots, they are a group of geniuses!"
"Now I finally understand why we lost. Just the gap in intelligence work has proven that we will definitely lose!"
"This is the Chinese telegraph code book in my hand. They are simply a group of geniuses. Their codes are not arranged according to Chinese characters, but are arranged using radicals. Can you tell me who of us can understand Chinese characters? Where’s the radical?”
"Not only that, they also use a two-layer password. The first layer uses numbers. Each number represents the coordinates of different books!"
"Look at this book, it has been folded to the page of "Four Books". What does this mean? It means that the answer to today's secret message must be found in the book "Four Books"!"
"The numbers are the number of pages and the number of words per page! The sixth word on the third page... the first word on the eleventh page... the fifteenth word on the eighth page... you have to find it like this , summarize it and then form a sentence!”
The intelligence officers around were also dumbfounded. "Four books? What kind of book is this? Is it four books? But there are no four books here. Where are the books?"
Molière collapsed, "Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu A must-read book for Chinese literati!”
"Of course there is no such book here, because this kind of book is a classic that all Chinese primary school students must memorize. Those who cannot memorize it have to slap their palms. The real code book is in the hearts of the Chinese people..."
"Look, today is the Four Books, tomorrow is the Five Classics... What is this? Is it the Disciple's Rules? There is also the Thousand-Character Classic... Wait, I thought of another question..."
Molière slapped his forehead, "Version! I forgot the version! Different books have different versions, which means that the versions are different, and the order of Chinese characters on each page is also different! If we don't know what the Chinese use What version of the Four Books is it, then we still can’t find the final answer!”
"Damn! How do these Chinese people's heads grow? Why are they so smart? Why didn't we think of that?"
Molière fell into a deep inferiority complex. In fact, he cannot be blamed for this. Humanity has just begun to use telegraph technology on a large scale. The submarine telegraph network that communicates around the world has not yet been built, and the coverage of the telegraph system is very low.
This is completely an emerging technology. Only governments and militaries of various countries can afford it now, and it has not been popularized at all. The birth and development of new things definitely takes time, and countries attach different importance to them.
Xiao Letian is bullying people, using the encryption technology of later generations during World War I and World War II to abuse intelligence officers in the middle of the 19th century. This is equivalent to a twenty-year-old boy bullying a kindergarten student.
Putting technology aside for now, philosophy determines everything. A mature philosophy is enough for him to bully others.
