At this time, the radio received a call signal. Pen ~ fun ~ pavilion www.biquge.info

Xiaolu brought two radio stations this time, one only receiving signals from Yan'an, Shenyang, and Beiping. It only receives but does not send, and even responds are exempted, which is the same as receiving instructions with a radio station.

The other part is in contact with Hong Kong, and it is sent and received at a fixed point on time.

The telegraph is a pioneer of long-distance communication for mankind, and many intelligent people have made outstanding contributions to this technology, and their communication ideas have had a far-reaching impact on the development of computers for future generations. For modern people, sending a message, a photo, or a video is as simple as pressing a button, but for a few decades ago, it was very difficult to transmit a piece of text remotely. If the text being passed is confidential, then it will be more difficult.

The similarity between the two is that the information is encoded. The encoding technology of modern computers was developed on the basis of the encoding technology of the telegraph. The great ideas of diasporic mathematicians have made human civilization advance by leaps and bounds.

The process of sending and receiving telegrams goes like this.

At the mutually agreed wavelength and time, the telegram is sent by one party to a specific simple method called: Are you there? According to the agreement, the other party heard the call and replied in the agreed way: I am here. Sender: Okay, I'll send the report. Pay attention to receiving. Recipient: Understood.

Don't you need a password or something? For example, the Heavenly King covers the tiger, the river demon of Pagoda Town, etc.? No, you don't. Because there are not many people who know this frequency, this time and this call sign, plus the two sides communicate with a password, even if the person who does not know the message is recorded, unless you know the password, it is useless, it is a series of meaningless numbers.

Is it really useless? It depends on who gets the numbers.

So, one sends and one receives. There may be interaction in the middle: I didn't hear this clearly, start again. Okay, attention, here we go. There are usually not many such interactions because everyone is very professional.

A telegraph operator is a professional, a very important position. One trick is fresh, eat all over the world. Why are those female spies in the movie dressed beautifully and talking so impulsively? Messengers and receivers, especially part-time translators, have access to core secrets. People have the ability, no matter which leader comes to power, they have to borrow from others.

The telegram received was ordinary code, which usually translates to nothing because it has been encrypted. The method of encryption is also agreed, such as a certain algorithm, a certain version of a book.

Because snooping is a method of obtaining intelligence, therefore, your above process will usually be snooped. If your password is deciphered, then there is no secret to be protected.

So there is a secondary encryption.

The one who compiles the code and the one who decipher it continue to wit it. Secondary encryption is a case in point.

The so-called secondary encryption is to encrypt the code once with one rule and then encrypt it once with the second rule. This greatly increases the difficulty of deciphering. Everyone is a master of mathematics, and they have the ability, and you can break it.

Because the European script is an alphabetic script, it is possible to establish the relationship between the alphabet and Morse code, and some algorithms can be used for encryption. So there was the Turing machine of Britain during World War II.

Chinese characters and Japanese characters are hieroglyphs, and the encoding and encryption rules will be different. The encryption method may also be different.

For example, many of the telecommunications personnel of the military command are from Jiangshan, Zhejiang, and it is more difficult to get through it in the Jiangshan dialect than the book of heaven, who can crack it?

Even if you don't know how to encrypt it, you can decipher it, but it takes a mathematician. There are some clever mathematicians in the Eighth Route Army, and some even stay abroad, who specialize in using mathematical methods to decipher: I will use mathematical methods to crack your secret code through calculation.

World War II, the application of the telegraph, coding, encryption, deciphering, all this requires the support of mathematical theories. These theories and practices laid the theoretical and technical foundation for the emergence of computers later.

In the fifties and sixties, there were computers, and in the early computer technology, traces of password encoding, encryption, etc. can still be seen.

After a while, the telegram was received and handed over to Xue Rui.

After the translation, the content of this telegram is still very strange, and it obviously needs Xue Rui to translate it again. Xue Rui took out a book and finished translating it in a short time.

Telegrams linked to Hong Kong will be encrypted again in addition to the normal encryption. Therefore, the content of the connection with Hong Kong is only known to the two of them.

Xiao Lu took the telegram, read it a few times, and was secretly happy in his heart.

In addition to commanding the work in Hong Kong, Kowloon, and even Guangzhou, one of the most important tasks of Xiao Liao in Hong Kong was to liaise with the German side. The other day, the German side lowered its trust in intelligence from China. The German in Hong Kong was naturally anxious, because his performance was not taken seriously enough.

This time, the man asked for information about opening a second battlefield, hoping to get some valuable information.

Xiaolu knew that in terms of intelligence exchange with Germany, although the beginning was very good, Britain was obviously much better than Germany in terms of intelligence, and Germany's spy network in Britain was destroyed, and all spies became double agents, and the intelligence played was true on the surface, and the quality of verification was naturally very high.

On the other hand, the information from Hong Kong has been verified to be both correct and wrong. This made the German leadership, especially Hitler, feel that Hong Kong intelligence was unreliable.

During World War II, intelligence warfare was even more exciting than war on the battlefield, and almost all operations were not secrets. For the same operation, there are always two different pieces of information sent to the table of the leaders of each country.

If a person, you look at it with your left eye, it is obvious that she is a woman, beautiful, elegant, noble and kind, very good, and she is about to chase and act, but with her right eye, she clearly sees that this is a man, vulgar, marijuana, and bad breath. I saw bad breath in my eyes, and I was terrible.

What to do?

I saw some things that shouldn't be seen with my eyes, such as bad breath. Trust that one eye?

Leaders often make decisions based on their own judgment rather than absolute trust in intelligence. When you see black teeth and exposed gums, you say you see bad breath. Seeing bad breath, that's how it came.

In the beginning, Koji's actions often did not attract the attention of Europe or even Japan, so he was able to surprise many of his actions. Later, Japan and Chongqing began to pay attention to him, and Xiaolu also had a way. One of the ways is to make some fake moves to make Japan and Chongqing think according to normal logic and be fooled.

Twenty days ago, Xiaolu sent a telegram to Hong Kong, and soon, the intelligence was somehow detected by the British side, and it was suspected that the Chinese side, that is, Chongqing, had leaked secrets. Chongqing quickly took action and began investigating the leak. Ten days ago, the military commanders tracked down Beiping.

The security services cracked the telegram of the military commander, alerting the small road. We must try to prevent this from happening again.

So, under the pretext of recuperating from illness, Xiaolu hid in the barren beach to avoid the spying of Chongqing spies. In this era when there are no satellites, who will notice the strange signals emitted in the Japanese occupation zone? Even if you notice it, the radio stations you send and receive are from the future, and they are almost impossible to decipher. If you can't crack it, you can only suspect the Japanese.

He wanted to rely on his advantage of mastering historical knowledge to fight alone against many excellent intelligence officers of several major countries, he wanted to make World War II go his own way, and he wanted to use the power of the Europeans and Americans to weaken themselves.

Xiaolu sent out the following information this time.

First, the Poles are double agents. It has been rebelled by the British.

Second, Garpao, the Spaniard who was ordered to enter England, was actually in Portugal, and the intelligence was a fabricated story. He had pledged allegiance to the British.

Thirdly, the British were implementing the Guardian Plan, the purpose of which was to convince the Germans that the Normandy landings were nothing more than a feint to prematurely deplete their reserves. The head of Project Guardian is Lieutenant Colonel John Bevan, nicknamed "The Chief of Fraud".

Fourth, send non-state intelligence agents to observe the garrison in Dover.

Fifth, investigate the whereabouts of a large number of Hollywood prop makers.

Each of these pieces of information has a thrilling, bizarre, and even bloody story behind it. Each of them is a typical case of information science. Any one that has been verified by the Germans is of great value. Taken together, several will play an inestimable role in the war.

The head of fraud, Lieutenant Colonel Johann Bivan, was known to German intelligence officers. How could German intelligence not know about its opponents.

Xiaolu is very confident, these telegrams, Germany will definitely pay attention. What is said in these pieces of information may not be understood by others, but the Germans must know. These things are the top secret of the Germans, and the names of the people mentioned here alone are the absolute secrets of the intelligence services.

Xiaolu knows that the first two items are almost impossible to verify, but with this information, Germany will analyze more of this information. How could someone who is not a person who knows the inside story know this kind of information?

The Polish name is Brytis, who was originally a fighter pilot, and later transferred to the Polish army command. After the outbreak of World War II, he was sent to study at the French Military School, where Brytis participated in the French anti-fascist resistance movement and organized the Allied intelligence network. The intelligence network was broken by the Germans, and Brutis was arrested by the Gestapo because he drew a map that was appreciated by the Germans and became a double agent. Later, he was sent from Madrid to London to gather intelligence for the German army.

Upon his arrival in London, he reported to the head of the Polish Resistance High Command in London, who reported the facts to British intelligence. From then on, he cooperated with British intelligence agencies and provided a large amount of information designed by the British to Germany.

At present, the German spy network in London has been greatly damaged, and only the Poles and others can spell a small amount of information. Therefore, his intelligence was highly valued by the German high-level, and he was also appreciated by the German intelligence services.

Xiao Lu threw out this name to let the Germans know that the Poles are not a secret, even the intelligence traffickers in Hong Kong know him, is he still reliable?

As for the Spaniard, Garbo is even more legendary.

Garbo was a Spaniard, and twice in 1941 he asked to join the British intelligence service, but was denied.

In July 1941, Garpen took refuge in the German intelligence agency and was ordered to infiltrate Britain through Portugal, but when he arrived in Portugal, he lied to Germany that he had entered the United Kingdom, and based on some newspapers and magazines published in the United Kingdom, with his talent for making up stories, he fabricated some information.

Shockingly, most of this information is true. The maker of the lie, "Garbo", was therefore highly valued and trusted by Germany.

Biwan, who is in charge of the Guardian Project, takes a fancy to Garbo because he needs everyone to lie like Garbo. After the rebellion, Garbo pledged allegiance to the British Empire. The British developed a number of carefully planned true and false information, which were sent to Germany in a steady stream through the hands of Garbo. Garbo became an ace agent of German intelligence and was tasked with finding out the Allied landing plans.

The third piece of information, Germany must have known.

The last two are the key. To reconnoiter the British garrison, the Germans used some aircraft to reconnoitre. To this end, the British resorted to deception, making a lot of fake cars, fake tanks, fake planes, and even fake tire prints. Many of these cheating jobs are designed by Hollywood prop masters. In addition, the extent of damage to the German spy network in the United States is very light, so it should be easier to investigate these prop masters.

Hollywood studios have not only made a lot of camouflage facilities for the US military, but also made a lot of camouflage for the Allies, and even fake communication signals, deceiving German scripts, and they are everywhere.

However, Koji knew that although the last two were intelligence, the tone seemed to be directing the German intelligence agencies, and he hoped that the Germans would take it seriously.
