"By the way, didn't you say you have something to ask me about? Just tell me! Whatever I can help you with or reveal, I will try my best to help you answer it."
Lin Mo heard this and said: "Director Wei, it's like this. We have encountered a headache problem, that is, communication is extremely poor during action, which greatly affects our actions.
There are currently two ways to communicate during action, one is manual communication, and the other is communication by phone, but both have various limitations and shortcomings.
There are two types of human communication, one is continuous communication by people, and the other is simple communication using agreed whistle gestures.
The former consumes too much manpower and has a certain lag. It may not be delivered in place when tracking and monitoring moving targets. Moreover, there are many people coming and going frequently, which only increases the risk of exposure.
In the latter case, the information that can be exchanged is limited and there are certain distance restrictions, which also increases the risk of exposure.
As for telephone communication, a dedicated line can be used for communication when monitoring fixed targets, but it also increases the risk of exposure, and it is not useful when monitoring mobile and non-fixed targets. At this time, most of the time, existing telephones installed in public or stores are used.
Communication, this method is cumbersome, and there may not always be a ready phone available.
Based on these problems encountered during the operation, I imagined a portable mobile short-range communication tool. I remembered that you, Director Wei, designed a miniature domestic radio station, so I wanted to learn from your experience and discuss the feasibility with you.
"
"Wait a minute..." Wei Daming spoke, thought for a while, and asked: "You should still want to entrust us to research, develop, and manufacture it for you, right? You shouldn't tell me this alone.
Instead, you should report it to your superior and then negotiate through formal procedures."
Lin Mo listened and hurriedly said: "Director Wei, I am also aware of these procedural matters, but my personal understanding of radio knowledge and technology is really limited. I don't know whether my idea is feasible, so I want to discuss it privately.
We will consult with you first, come up with a feasible plan and reach an agreement, and then formally go through the procedures. This can also avoid going directly to the procedures. If everyone communicates and understands poorly, there may be some misunderstandings, or there may be some things that are inconvenient to say publicly.
Let this matter be miscarried, and it will also affect everyone's relationship and harmony."
Wei Daming thought for a while, nodded slightly, and reluctantly agreed with Lin Mo's statement, and said: "Then tell me about your specific ideas for this...portable...short-range communication tool! Let me see if it is feasible first."
Lin Mo nodded and said: "What I envision is that it is the size of half a cigarette, weighs less than one kilogram, and can carry out voice communication over a distance of about one kilometer..."
"Wait..." Before Lin Mo could finish speaking, Wei Daming raised his hand to interrupt, frowning and said: "It seems that what you just said is not bad, we really need to communicate in advance, otherwise your idea will not work for me."
If you really know how to do it, you can directly deny it.”
Hearing this, you were confused for a moment. You didn't know what the problem was and why Wei Daming refused directly.
Seeing Lin Mo's puzzled look, Wei Daming reminded: "If you use walkie-talkie communication, are you still going to use dialect to communicate?"
After hearing this, Lin Mo finally understood that the idea he had come up with before had now become a hindrance?
Lin Mo was a little reluctant and asked: "Director Wei, the use of dialects as a means of confidentiality is also used. It doesn't need to be so tightly covered, right? How many dialects are there in the country? Too many to count, right? There are not enough dialects.
, and ethnic minorities can also use their languages as a means of confidentiality!"
"This is not how it is calculated. It cannot be equated with how many dialects and languages there are. It is about the fact that the enemy cannot know it in advance."
When Lin Mo heard this, he was a little confused again. Seeing Lin Mo like this, Wei Daming also knew where the other party was confused. To be honest, he only became aware of some things recently.
After thinking for a moment, Wei Daming said: "Let me introduce you to some basic information! Thanks to the seized code books and support from all sides, the telecommunications room has made some progress and results in its recent deciphering work.
But this is not the most important thing. The most important thing is that I discovered a problem, that is, the confidentiality of the current encoding method is not as good as imagined.
Can you understand this? Although we are only deciphering Japanese historical telegrams, and that set of codes has been abandoned, our conditions are not good. At least our personnel, experience, equipment, etc. are not as good as those of the Japanese.
, give us some more time, I estimate that deciphering some of the current communications of the Japanese is also a high probability matter, it is just a matter of how much.
I say this not to praise myself, but to feel deeply worried, because I know very well that Japan’s deciphering ability is superior to ours, its coding ability is superior to ours, and the confidentiality ability required to decipher telegrams, code books, etc. is inferior to ours.
Above, we can decipher their communications, there is no reason why ours cannot be deciphered by them.
When you came in, this is what I was thinking about. Our confidential communications are probably a sieve for the Japanese. I guess the one-to-one communication with independent codes like our intelligence department will be better, but the military
, I guess there is a big problem with those sets of secret codes commonly used by diplomacy and even intelligence agencies.
Because judging from the current situation, the Japanese have penetrated us very seriously. The things needed to decipher code books, secret code contents, etc. will definitely not be as difficult as ours. And these sets are widely used and used frequently. In this situation
It is not difficult for us to decipher it ourselves, let alone Japan, which has stronger deciphering capabilities.
Now you can understand why you are not allowed to communicate in dialect? Because this is another method of confidentiality, and it is a method that is likely to change the status quo, and it cannot be easily discovered by the opponent in advance."
"Director Wei, do you have to hang yourself on a tree and pin all your hopes on it? If the encoding is not good, then strengthen it. If the secret is leaked, then strengthen your own confidentiality, counter-espionage, and speed up the frequency of updating the code book, etc.
There are many ways to increase confidentiality!”
This chapter is not over, please click on the next page to continue reading! Lin Mo is still unwilling, and he always feels that something is wrong, but he can't think of it for a while, but one thing he remembers is that voice communication played a big role in World War II.
This method of communication was promoted to the grassroots, but the telecommunications office did not seem to realize this. Lin Mo felt that this road was probably going astray.
"Alas..." Wei Daming sighed helplessly. He felt that Lin Mo still didn't understand the meaning of his words, so he patiently explained again.
"The methods you mentioned can indeed enhance the confidentiality of communications, but this is not the key. The key is that the current confidentiality methods are inherently poor in confidentiality.
Take us, for example, to be able to decipher communications that are far more confidential than our own under the condition that the deciphering methods are far inferior to those of our opponents. This shows that this kind of confidentiality method is inherently poor in confidentiality. The methods you mentioned are
On this basis, sewing and mending cannot solve the problems that exist in itself.
The current secrecy methods of the Japanese are beyond our reach, and they can be deciphered by us who are much weaker in deciphering ability. With our current secrecy ability, it is estimated that some knowledgeable personnel organized by the Red Party can also decipher it, and even our secrecy methods
If we catch up with Japan, we will not be able to stop Japan, whose decryption capabilities are still superior to ours, and it will be extremely difficult to catch up with Japan's confidentiality capabilities."
This time, Lin Mo finally understood and figured out what he felt was wrong. Moreover, he also realized a problem. The two of them argued and argued, but their emotional concerns were not in the same place. There was clearly an information gap.
, Lin Mo didn’t notice Wei Daming’s concern, and Wei Daming didn’t know what Lin Mo was struggling with!
"Director Wei, I understand now. What you want to express is that the currently used secure communication method has its own problems. In some cases, such as if it is used more frequently, it can be easily deciphered, right?
"
"Huh..." Wei Daming breathed a long sigh of relief and said with a smile: "I finally made sense to you kid. It's so useless to explain..."
Lin Mo also smiled, and then said sternly: "But Director Wei, using dialects to communicate can't solve the problem? For translators, it seems that dialects and code beeps are no different, and dialects can only be counted as one.
Set...an alternative password.
If we understand the content of the code sent by dialects, regardless of which dialect is different, and just treat the dialect as a set of code to decipher, then there should be no essential difference between deciphering it and deciphering the code, right?
After all, dialects are also a kind of Chinese. They just speak different words, but they express the same thing. So the different pronunciations can be regarded as the different ticks of the secret code.
The language of ethnic minorities is not acceptable, or any language is used. They are essentially the same in content. They all represent the same idea. The difference is only in the different forms of expression on the surface. As long as
Regardless of the language, it can still be deciphered as a set of secret codes."
This is what Lin Mo felt was wrong before. Of course, this does not mean that other languages cannot be used as a means of confidential communication. After all, there is a precedent for the success of the Navajo code in World War II.
It's just that the U.S. military can play well, but it doesn't mean that the national government can do it. After all, the national government has the ability to keep secrets. The Japanese have a high chance of getting the rough or even original content of the telegram. As Lin Mo said, it doesn't matter what language it is.
, it can be deciphered directly as a set of passwords.
"I really didn't expect this..." Wei Daming frowned deeply and said: "It seems that you are right when you say you can't hang yourself on a tree. The confidentiality work must be carried out in parallel, and you can't give up all hope.
Rely on something.
However... language can still be used as a means of confidential communication. Although its problems are not essentially different from cipher codes, it is at least a new form of cipher. It still uses ready-made things and can reduce the need for manual compilation.
The security of deciphering personal habits, preferences, rules, etc. in passwords will be much higher than compiling passwords."
"Director Wei, I still stick to my idea of using Mandarin as a means of communication and dialect as an encryption method of communication..."
"You..." Before Lin Mo could finish speaking, Wei Daming almost wanted to get angry, so Lin Mo hurriedly explained.
"Director Wei, I find that we still haven't communicated clearly. Our starting points on this issue are not consistent. You just explained to me that your starting point is the confidentiality of communications. Are you willing to listen to my starting point on this issue?
Woolen cloth?"
"Okay, then tell me..." Judging from Lin Mo's unhurried look, he probably had something in his stomach. Wei Daming also became interested and wanted to hear what flowers he could tell.
Seeing this, Lin Mo didn't hide it and said: "Director Wei, I want to use dialect for communication. The reason is not confidentiality, or confidentiality is only a secondary reason, dialect is the main reason.
Because there is a huge advantage in voice communication that cannot be compared with code communication, that is, the requirements for users are extremely low. I believe Director Wei knows better than me how much time and energy it takes to train a qualified code operator.
.
At present, radio stations in our army are generally only distributed to the division and brigade level. If we want to continue to distribute them to lower levels, we are faced with two main problems, one is radio equipment, and the other is radio operators.
Radio equipment can be solved with money to a certain extent, but it is difficult to train qualified operators, because every time the radio station is assigned to one level of troops, the operators required must be from the higher level troops.
several times of.
At present, the establishment of domestic troops is relatively chaotic. Let's assume that a division and brigade have three regiments. It is a simple estimate that the number of radio operators assigned to the regiment level must be three times the number of radio operators assigned to the division and brigade.
This does not include other regiment-level or important directly-affiliated units under the division and brigade. After the division and brigade are assigned downwards, the additional communication personnel required to make the communications of the division and brigade busier, as well as the reporting personnel required to be attenuated due to sacrifices, injuries, etc., are required to reserve the information.
If personnel are assigned to the battalion level, this problem will become even more severe. After all, the lower the level, the more they need to face the battlefield directly, and the danger will increase rapidly.
But the walkie-talkie equipment is different. Just recruit a soldier, train for a few days, and a walkie-talkie who can simply operate the walkie-talkie equipment and communicate with the microphone will come out. Even if the maintenance of the equipment is included, find someone with some knowledge.
Soldiers trained in March or February will become qualified walkers. Without the obstruction of general training personnel, if they are really willing to spend money, walkers can even be promoted to the company level.
Director Wei, you are engaged in communications. You should be very clear about the benefits of extending wireless communications to regiments and camps or even to the company level. Promote walkie-talkie communications. Walkie-talkie communications use dialects as a means of confidentiality. I personally think this is the way to maintain confidentiality. The correct application of.
There are so many dialects in the country that one dialect can be used for communication within an army or even a division. I even feel that this method is more confidential than using dialects for confidential communications.
After all, the confidentiality level of communications within the division and brigade level is not very high. The opponent will not allocate precious deciphering power to decipher it like a code. Even if they do mobilize people to decipher it, there will be as many handsome brigades as there are How many sets of codes are a big project to decipher, and we can replace a new batch of communicators after a period of time, or even just exchange the communicators between different units, which can cause great trouble to the opponent and ensure as much as possible Communication security.
I insist on using walkie-talkie communication, also because of the advantage of walkie-talkie, so that the team members can get started quickly. After all, let’s not talk about whether we have the talent to become a telegraph operator. The long training time alone is not enough for us. Acceptable.”
