Is it possible in reality that spy dramas often tap Morse code with their fingers for secret communication?

In reality, this kind of plot cannot happen unless it is absolutely necessary. Li Bai, in the movie "The Immortal Radio" adapted from real events, sent out the last simple message "Goodbye, comrades" when the spy approached him.

But as a spy, no matter whether the message is plain or encrypted, under normal circumstances, he will not make such a deadly move in front of the enemy or unidentified people, even if it is a habitual move. As long as an insider around him notices a casual fingertip abnormality, not only the sender but also the receiver will die together, and there is no need to understand the communication content at all. Callus will form on the index finger and middle finger of the operator who sends and receives information all the year round. People who know will know if there is any.

In addition, in public, you can't contact each other with encrypted information. Few people can memorize all the layers of the encrypted codebook and put them in their heads. This practice is also not allowed by intelligence work. Once caught, it will cause their own entire password system to be completely confidential. If you are surrounded by professionals in the industry, the fingertip movements you communicate in plain code will be accepted by all the professionals in the industry. Encrypted messages are basically difficult for the other party to understand in a short time.

The TV series Assassination is the work of Liu Yunlong. There are three theories, one is that the signal was intercepted, and the other is that Huang deciphered the signal. From this point of view, the two are related but independent, and the transceiver only knows how to send and receive the numbers 0-9 according to the frequency of the radio station, but does not know the content of the message. The encryption, decryption and deciphering of message contents are completed by others or departments. The higher the message level, the more difficult it is to decipher the encrypted message layer by layer. Even an excellent translator or confidential secretary needs the help of a codebook to decipher and form a text.

Morse code, as a general communication, is basically composed of 26 English letters and numbers from 0 to 9, which are converted into dots and dashes (ticks). If you use this method, as long as you have a little common sense of Morse code, you will know the content of plain code communication. This is the way for Tony Leung Chiu Wai to contact the police in the Hong Kong movie Infernal Affairs, but Tony Leung Chiu Wai is blind in Morse code (there is no sound and he can't monitor himself), so it must be done at once. Within a certain range, as long as a radio enthusiast receives the news on this frequency and all the news is exposed, Tony Leung Chiu Wai will die.

Now Morse code telegrams are basically divorced from political, military and commercial communication, but there are still many radio enthusiasts in use all over the world. If it is not encrypted information, all frequencies are basically confidential. Even if it is only simple encryption, these enthusiasts can easily decipher it. Don't think that the local radio management committee is idle. There is a lot of information here.

So, don't fool the audience, and the audience shouldn't take it seriously. There are always people who know. Yang Zirong can also speak slang in bandit caves, can't he?

No way! Again, impossible!

The sound or action produced by tapping with fingers in a spy war drama can convey information and intelligence, so that the surrounding companions can understand the information and intelligence content he sends. It's completely impossible, and it's a striking nonsense stunt in a spy war drama.

It's really a layman watching the excitement, and an expert watching the doorway!

I used to be a telegraph operator, dealing with Morse code for many years. Morse code transmits information and intelligence, the most critical and only point is to transmit content through sound, which is absolutely impossible without sound transmission.

In order to transmit telegrams by radio, the inventor of Morse code used two very simple Morse codes, namely "drip"-short code and "answer"-long code, which made up 10 Arabic numerals and 26 English letters, and spelled out millions of passwords. Translating passwords into words is information and intelligence.

The receiver of the telegram must distinguish the length of Morse code by hearing, so as to record the numbers or letters sent by the other party. It is impossible to distinguish the information content only by the sound or action generated by finger tapping.

Of course, spy war dramas pay attention to adventure and bizarre excitement, so it is ok and understandable to let everyone see the excitement in some ways that laymen can't understand!

I have received professional radio transceiver training and am a senior signalman. I can answer your question.

If both parties have received professional radio training and are familiar with communication terms, theoretically, they can communicate by tapping Morse code with their fingers.

Simply put, numbers or letters can be represented by "dots" and "strokes" (hooks). For example, the letter "a" can be represented by "ticks" (1). The letter "B" can be represented by "Answer Didi Didi" (I ……). "Answer" is three times as long as "point".

The emergency distress signal SOS can be represented by "111".

OK can be expressed as "1111.1".

The American film Hunting U-57 1 has such a scene. The captured German officers hit the submarine wall with hard objects and sent out SOS signals, trying to let the surrounding German warships find it.

If two people face to face, using Morse code to communicate is actually inefficient and easy to be found. It is best to use words or eyes or body movements quickly. If you have to use it, you can only use phrases, that is, specific phrases composed of several letters. If a large amount of information is transmitted, tapping Morse code with your finger is very troublesome and easy to expose.

In modern society, it is very backward to communicate with Morse code. There are many more advanced and convenient contact methods now. Even in the army, morse code is rarely used to communicate.

It's definitely not a universal cipher text, it should all be agreed, and simple instructions should be achievable. For example, several specific actions, such as three long and two short, are running away, and three short and two long are keeping up. Of course, it may be shorter or shorter. It is basically impossible to communicate like a normal conversation.

In real life, both sides need to know Morse code in order to really communicate. If one party knows and the other party doesn't, communication is useless. As the two-part allegorical saying goes, it's no use squinting at the blind. Only when both parties understand and have an agreement, and no one around them understands and doesn't know what is going on, private Morse code exchange is effective and meaningful. Otherwise, it is unrealistic to communicate with people who don't understand Morse code.

I began to participate in the telecommunications training of the People's Armed Forces Department from junior high school. There are three students in our class. One is a girl, so we can't play together. The other has a good relationship with me at ordinary times. After the exam, I tapped on the table with my original ballpoint pen to check the answers. There is no problem with fill-in-the-blank questions and multiple-choice questions, and the calculation questions and questions are too complicated. Neither of us can recite the whole password book.

This process continues until the end of the second year of high school. There was basically no exposure during the period. Only a few teachers were too noisy to let us be quiet, but I pretended to be thinking and the teachers didn't say much else. But the main reason is that my classmates and I have similar grades, and answering each other is just a little more fun.

As for the plots in movies and TV series where gestures and winks can convey information, they can only be regarded as jokes. A Chinese character has four numbers, a number has five scales, and ten words in a sentence need to blink 200 times. Not to mention can't see clearly, two people so affectionate, concentrate on blinking, next to the spy can see that something is wrong.

I watched a lot of spy TV dramas and movies. For example, Yifeng Li (played by Chen Shen) and Adi (played by Li Xiaonan) in Sparrow use their fingers to transmit information to each other in the enemy interrogation room, and it is more appropriate to exchange information. However, Chen Shen's communication with Xu in the interrogation room was a bit far-fetched and was discovered by spies. Isn't this a desperate thing? That's to save Xu. This is the rhythm of mutual destruction.

You can use simple common expressions. There are usually public service terms between operators, such as: bad signal, repeat, ok, change frequency, 999 (fuck off) and so on. If you say one thing, it is impossible. You need to translate this information.

It is feasible in theory, but it is difficult in practice and can be used in special occasions.

I don't know if Infernal Affairs has started, but it's really cool to watch Tony Leung Chiu Wai's Chen Yongren contact his boss in Morse code.

Later, it was discovered that in various spy wars and movies and TV plays about police and bandits, there were more and more scenes in which agents and police contacted each other by Morse code.

In the movie "The Wind", agents carve Morse code on cigarettes, and agents played by Zhou Xun can sew what they want to say on their clothes in Morse code, and then wear it on themselves and send it out. Its usage is amazing.

In other TV dramas, some agents tap the table with their fingers or tap their heads to indicate Morse code, and some agents tap the telephone microphone with their fingers to knock out Morse code (Infernal Affairs).

In the movie Acts, there is actually a scene where Nick Cheung uses a pistol to type Morse code. In addition, Nick Cheung and Louis Koo also used Rubik's Cube to represent Morse code, and the film even printed Morse code "Brothers" on the movie poster.

Then, netizens can't help asking, can Morse Code (formal name: Morse Code), which was invented by/kloc-0 in 837 and stopped using internationally in/kloc-0 in 999, only be communicated by agents with "Didi Dada" and "small strokes"?

We watched the movies on the cliff, and both sides of the spy war paid special attention to a book called Mei Lanfang's trip to America. This book is the contact code used by the underground party, mom. Its function is that after receiving the contact signal, the agent translates the instruction by comparing the signal with the cipher mother. No password, mom. The signal is just a useless number.

Similarly, in the TV series Latent, Yu Zecheng's password parents are also the novel Butterfly Dream.

Historically, there have been many real spy stories around password mom. Zhang Hao (Lin Yuying) once crossed the Mongolian plateau and desert from the Soviet Union to Yan 'an. The most important thing on him was a codebook.

In other words, if two agents face to face and want to transmit information in Morse code, it is theoretically feasible, provided that their brains are very easy to use and can remember the whole codebook, and at the same time, their brains can quickly identify, retrieve and translate electricity. Usually, this work is done by three people in the radio station (sender, receiver and translator). In a tense environment, the agent can complete the whole work alone without any equipment.

Someone in history can really remember the whole password book, and so will Pan Hannian. Others can't remember it as long as they work hard, but they can complete the whole process of transmitting information in a short time. At least no one in history can do this.

So, what if the agent uses Morse code instead of password? Of course, it is also feasible in theory, which is equivalent to the consequences of Liao Yaoxiang's propaganda in Ming language in Liaoshen Campaign. Everyone present can see what the agents are doing, and anyone who knows a little morse code can understand what the two agents are transmitting, which is too dangerous. After all, the agents of the Central Committee, the Military Commission and the special high school courses are not free.

In addition, if it is a public place, such as a teahouse or a coffee shop, the two agents don't talk across several tables, tapping the tables or cups with their fingers endlessly face to face. This kind of practice does not require spies to come and arrest people. I am afraid that the mental hospital will arrive first.

You know, displaying a word in Morse code is not a simple process. After all, Morse code only has a simple "Didi Dada" or "little strokes" to form a sentence, which is a very long message. Therefore, it is theoretically feasible to use Morse code to transmit information on many occasions, but it is basically difficult to realize it in reality.

But under special circumstances, agents still have special methods.

For example, Morse code also has a simple phrase expression, and the most common one is "SOS". I believe most people will know what it means when they see this signal.

However, most agents use pre-agreed signals when transmitting simple information. In principle, it is much safer than ordinary Morse code.

Yu Zecheng and Ping Cui agreed to ring the phone in a "latent" way. What do you mean by hanging up after a few rings? But the author has always wondered, in the era of crank phone and turntable, can the ringtone of mobile phone really be controlled to such an accurate degree?

In addition to using Morse code everywhere, agents in the wind also use the change of Beijing opera singing to convey information. I'm afraid this way requires professional training in advance.

In Above the Cliff, all the participants in the outrat operation have been trained, and they have a contact password that only they can understand, but this password is not safe because of Xie's rebellion.

Of course, the most common contact method is to set a fixed code name. For example, the Japanese army set the code name "Midway Island" as "AF" before the naval battle of Midway Island, which made the American military decipherers very crazy and finally had to use trial and error to decipher it.

There are also some common knocking methods in film and television dramas. It's safer to tap a few times to represent who is also a specific code than to use Morse code.

To sum up, Morse code in history is very useful, but because it is very useful, many people can do it. It is actually very difficult for agents to use Morse code to complete contact secretly. Therefore, most of the Morse code contact information you see in film and television dramas is just an artistic need.

Morse code is an on-off signal code, which represents different English letters, numbers and punctuation marks through different arrangement orders. Invented in 1837, it plays an important role in early radio, which is necessary for every radio communicator to understand.

Morse password is simple and clear, and there is almost no ambiguity. The code is mainly represented by two characters: ""and "-",one is long and the other is short, which is used in many occasions, such as sending distress signals. In the movie Wind, Moore code is sewn on clothes to spread the news. This method is used in the cartoon Detective Conan and Reasoning Confrontation, New vs Okiya Subaru (tv5 1 1). When Moore's password light is used to call for help, it is defined as "-"light is on for a long time and "."When the light is on for a short time, then all kinds of information can be sent out through the switch of the flashlight, such as distress information. If the lights are displayed according to the law of "short bright dark short bright dark short bright dark short bright dark long bright dark short bright dark short bright dark short bright dark short bright short bright short bright short bright short bright short bright short bright short bright short bright short bright", then it means SOS.

It IS said that on June 20 15, 1 2006, Kenji Goto, a Japanese hostage kidnapped by the terrorist organization Islamic State (IS), typed Morse code with blinking in a video released by IS, and the message was "Don't save me".

I found some information about tapping Morse code with my finger. For example, I like you. Here's the thing: .................................................................................................................................................., as for how to knock, what is the time interval? I don't understand, so netizens will make do with it.
