Cryptographic transmission and confidentiality

? This should be the memory of the army. There is a subject called password transmission, that is, the army marches at night, and in order to pass orders orally in front of the team, one by one from front to back. From the moment when the first soldier received the order and sent it back to the moment when the last soldier received the order, the results were often quite different. For example, the order is' full speed ahead', which may eventually become' want to eat chicken roast'. This is just an example. Why is there such a result? It is precisely because the soldiers of the army come from all corners of the country, and their dialects are homophonic, which will inevitably lead to such a result. This is part of the usual training. Imagine that if you fight, you will turn' forward' into' run'. Wouldn't that delay the fighter plane and ruin the army?

From here, we can see the importance of popularizing Putonghua, especially in the army. Then, the problem I want to explain here is that even such a simple password, if misunderstood by people, will lead to very serious consequences. If it is between countries, it may lead to the service of its own guns and sacrifice many young lives. If you are friends, it may lead to enemies between friends. There will be unnecessary doubts and guesses between husband and wife, and they may become strangers from now on.

So, when you don't understand its true meaning, don't listen by mistake. From the beginning of the communicator to the end of the listener, you may not mean to hurt others, but the result is self-evident due to misunderstanding. Therefore, seeing is believing, hearing is true, and sometimes it is not credible.

Let's talk about secrecy first. Secrecy is a very important confidential matter in the army. The requirements for military personnel are quite high, and there are special "confidentiality regulations" to regulate the confidentiality awareness and behavior of military personnel.

What I said was a joke about secrecy, and I can't remember the specific content. The general idea should be good, plus my own interpretation. It is said that friends Zhang San and Li Si exchange information together. Zhang San said that he recently heard a news that the rooster lay eggs of Lao Wang's family was very interesting. The rooster lay eggs, contrary to common sense, the Lao Wang family must have suffered recently. As far as I know, Lao Li, we are best friends. I told you, don't tell anyone. Remember: keep it a secret!

Every other day, Li Si meets Liu Zhao and says, I heard something very strange yesterday. It is said that the rooster lay eggs of Lao Wang's family died. She not only laid eggs, but guess what, she also laid duck eggs. Do you find it strange? You're my best friend, man. That's all I'm telling you. Remember, keep it a secret!

One day, Liu Zhao met Xiao Cui and told him the story. Xiao Cui thinks the material is good. One night, I said in the column of Xiao Cui Shuo Shi that I have a strange thing to tell you today. It is said that the rooster of Lao Wang's family laid a duck egg, and it was salted duck egg. You see, the secret has not been kept, and the taste has changed completely. Everybody knows that! You see, confidential things finally became news. It can be seen from here that the more confidential things are, the more public things are.

So it can be concluded that you should not trust your eyes and ears too much, and (typical magic) you should also control your mouth. This information should be digested by your brain and heart. Don't please your mouth and hurt everyone's heart!
