Lin Gao Qiming

Chapter 436 Password

Knowing who a specific codename refers to is key.With this, these materials become out-and-out black materials, and the lethality thrown out is much more powerful than a "three festivals and two longevity" gift slips.Just as the "unspoken rule" female artist is lace entertainment news, rape of a female artist is a criminal case.

Lin Baiguang believes that it is impossible for Gou Er to have a superhuman memory to remember the characters referred to by each code, and most likely there should be a comparison table between codes and names as a reminder.

But Lin Baiguang wanted to get this question, so Gou Er naturally wanted to.The sorting of materials is coming to an end, but Sun Xiao still hasn't found the most valuable roster from the ledger.Lin Baiguang's complexion turned sour: I found very valuable materials, but they couldn't use them. It was so disappointing.

"You don't have to be too disappointed, maybe Gou Er memorized it by himself," Mu Min comforted him, "or he carried this booklet with him. In addition to looking for information directly, you can also use intelligence analysis way to find out what the codenames refer to."

"Comparing the materials, you can generally know where this person is, what he is doing specifically, who he is in contact with, and you can guess who it is." Mu Min said, picking up the bribery booklet, "This booklet The Lanling Weng mentioned in the last incident received money to talk to Wu Mingjin about the matter, and the matter was settled, obviously this person is an acquaintance around Wu Mingjin, and the relationship is still very unusual."

"I also thought of this," Lin Baiguang said, "but there are quite a few cronies around Wu Mingjin—it's hard to confirm who it is. Besides, if Wu Ya, the county magistrate, or an important local gentry came forward and said, he would not I am ashamed to reject it on the spot.”

"So we have to look at the materials together, so that we can infer it."

After clearing the boxes to the end, I finally found what Lin Baiguang needed: the roster.

When Sun Xiao brought it, Lin Baiguang was overjoyed. With this thing, he was about to catch a lot of the bezoar and dog treasures in the stomachs of these officials in Qiongzhou Prefecture!

When I opened it, it was immediately cold.It turns out that this is a comparison table.Each page of the ledger is divided into upper and lower columns. The upper part is the code name of the person mentioned, while the lower part is a meaningless three-letter word combination. Judging from its weirdness, it cannot be the name of a person at all.

"Damn, this Gou Er is really a ghost! This is probably another kind of code!"

Mu Min thought it might be a kind of password, but she knew nothing about it. They searched the personnel database through the computer, and they found the password operator: Zhang Xingpei.

Zhang Xingpei had just come back from Guangzhou and was enjoying his vacation - in Guangzhou he received an excellent reception: he played with four or five women in one go.It's exhausting.After returning to Lingao, I only thought about self-cultivation.But a phone call summoned him to the Political and Security Administration.

Zhang Xingpei was uneasy, and thought several times whether he was sorry for the time travel group. Could it be that his "life style" in Guangzhou was reported?It seems that the Political Security Administration doesn't like to take care of this kind of lower body matter... After much deliberation, I couldn't figure it out, so I had to report here.

"Look at these things, are they passwords?" Lin Baiguang cut to the chase.

Zhang Xingpei has a strong interest in cryptography and information science, and has also studied it himself.Of course, his cryptography can only be regarded as the most basic entry level.When he heard that he was engaged in ciphers, he was startled—almost all his cryptography examples were based on Western ones, and he had no idea what ancient Chinese ciphers were like.

"This is difficult. I don't know anything about ancient Chinese ciphers..." Zhang Xingpei hesitated, "The ancients probably wouldn't use too complicated ciphers, but it's not easy to do it if you don't know the system inside."

"The principle should be the same, right?"

"It's hard to say." Zhang Xingpei said, "China has [-] commonly used characters, while the Western system consists of dozens of letters. From the perspective of encoding, letters are obviously much easier than square characters."

The huge difference in writing between China and the West has resulted in completely different concepts on secretly transmitting materials.In ancient China, more incisions and lingoes were used.Zhang Xingpei knew a little about this kind of incisive language, and it was basically passed on by word of mouth, which was not the same thing as a password at all.

"Hurry up and call Luo Duo and tell him to look up ancient Chinese codes!"

"It's the middle of the night now, it's not moral to disturb people in the middle of the night—" Zhang Xingpei was already very dissatisfied with being summoned late at night, so he took advantage of it.

"Don't worry, these two bookcases must be in the office of the Social Work Department." Lin Baiguang is obviously not interested in public morality, and he is very familiar with Luo Duo's habits-this person's greatest hobby is to collect materials, and he becomes more energetic at night it is good.

But Luo Duo, who was called, couldn't provide more information—it was midnight, and he couldn't go to the computer center of the big library to search. According to his limited memory, Zhang Xingpei generally knew that the ancient Chinese military codes were mainly There are two kinds: one is the "argument" similar to the "incision" of the Jianghu, but how this lingo is used is now unclear.

There is also a so-called "word test".That is to compile various situations that may be encountered in the army into forty items, such as: "Please bow", "Please ask for arrows", "Please enter the army", "Please ask for reinforcements" and so on.Then contact the two parties and agree to use a five-character regulated poem without repeated characters as the "character test". Just add one very good.In this way, even if the letter falls into the hands of the enemy, the other party will know this method. As long as the bottom book of the item number is not leaked, even knowing which poem it is is useless.

"...But this method is mainly used for communication. If Gou Er only uses it to prevent leaks, it's hard to say whether it is this way."

"Actually, it's just using words to represent the meaning. It's interesting and interesting." Zhang Xingpei fell into deep thought.

Then Luo Duo began to introduce a cipher invented by Qi Jiguang based on the pronunciation of Fanqie—this cipher is already very similar to modern ciphers, but judging from the complexity of what he said, people don't think Gou Er would use such a complicated cipher system.In fact, this kind of password was only used in the Qi family army for a short time, and it was not popularized.

Zhang Xingpei took a pen and copied down all the account books. One thing is certain now: these three-character words for no reason refer to the names of the people they refer to. He took this copy and looked at it carefully. After a few minutes, He found a breakthrough.

"I have some numbers." Zhang Xingpei pointed to the words above, "This is a simple substitution method, which is the so-called Caesar cipher."

"When did Gou Er know about Caesar?"

"Of course it doesn't mean that he used a Caesar cipher, but the principle is similar." Zhang Xingpei explained: The so-called Caesar cipher is to replace every letter in the plaintext with a different letter or symbol.According to the records: Caesar simply replaced each letter in the plaintext with the letter 3 behind it.

"But this is unlikely." Luo Duo immediately pointed out the meaning, "How many letters are there? There are more than 800 commonly used Chinese characters. How big is this word list? I have to carry a code book all the time. It's a thick code book."

"I'm not sure about that." Zhang Xingpei shook his head and said, "But I can probably infer a few surnames from the probability method."

His idea is very simple. Since these are all names, the first character of the three-character word must be a surname. Since it is a surname, there is a problem of frequency.Just as the most frequent letter in the English alphabet is e, Chinese surnames also appear frequently. Wang, Zhang, Li, and Chen are the most common surnames.Although Zhang Xingpei didn't know the ranking order of Daming's surnames, it should be very modern and there would be no big difference.

"You have to consider the local characteristics." Luo Duo reminded him, "For Lingao, the Fu surname is the common surname. There are many Fujian immigrants here, and there are also many Lin surnames."

"This is where the difficulty lies," Zhang Xingpei said. He singled out the characters of the most frequently occurring surnames.

"Too bad, I don't have any idea about ancient Chinese books," Zhang Xingpei said dejectedly, "Gou Er must be using an ancient book. And it's still very common—it seems like Europeans like to use the Bible as a password same table."

"I think I guessed one." Mu Min spoke suddenly, "The person who went to tell Wu Mingjin on behalf of Gou Er's son must be Wang Zhaomin—his master!"

All eyes turned to her.

"Look, the first of the three characters corresponding to this Lanling Weng is exactly the most frequently occurring characters found by Zhang Xingpei: Wang, Zhang, Li, Chen, plus Fu and Lin. Think about it Look, there is only one person close to Wu Mingjin who is more trusted, or someone who can talk, and who fits these surnames, Wang Zhaomin!"

"Not bad, not bad," Lin Baiguang nodded again and again, after comparing the information, he didn't think it was too strange.

"Comparing his bribery records and comparing the social situation in Lingao we have, we should be able to find out the names of many people. Fortunately, these are just names, and it is easier to guess."

It's hard to say about other places. The intelligence department of Lingao still has a lot of basic social conditions. Soon, they found the names of several people from the clues.

"However, the accuracy of guessing like this is still limited, and once you get out of the high school, this method will not be accurate." Mu Min said, "We still need to find out the word list."

"Let me look for it slowly," Zhang Xingpei said. "Now that I know a few characters, I can guess them. Let's start with the most popular surnames, the Three-Character Classic, and the Thousand-Character Classic—these three This kind, anyone who has read the book in Daming can memorize it.”
