Knowing who the specific code name refers to is the key. With this, these materials become out-and-out black materials, and the lethality of throwing them out is much more powerful than a "three festivals and two birthdays" gift sheet
.Just as the "hidden rules" of female artists are entertainment news, raping a female artist is a criminal case.
Lin Baiguang believes that Gou Er cannot have a superhuman memory to remember the person each code refers to, and he should probably have a comparison table between code words and names as a memo.
However, Lin Baiguang wanted to know this, and Gou Er naturally wanted to know it too. The sorting of materials was gradually coming to an end, and Sun Xiao still could not find the most valuable roster from the ledger. Lin Baiguang's face turned ugly: he found very valuable materials, but
It doesn't work, 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
method to find out what the code name refers to.”
"By comparing the materials, you can generally know where this person is, what he does specifically, who he has come into contact with, and you can guess who he is." Mu Min said, picking up the bribery booklet, "This booklet contains
The Lan Ling Weng mentioned in the last incident received money to talk to Wu Mingjin about the matter, and the matter was completed. Obviously this person is an acquaintance of Wu Mingjin, and the relationship is very unusual."
"I've thought of this too," Lin Baiguang said, "but there are quite a few close associates around Wu Mingjin - it's hard to confirm who they are. Besides, if the county magistrate Wu Ya or an important local gentry came forward to speak out, he wouldn't
I have the nerve to reject it on the spot."
"So we have to look at the materials together so that we can make inferences."
After clearing out the box, I finally found what Lin Baiguang needed: the roster.
When Sun Xiao brought it, Lin Baiguang was overjoyed. With this thing, he would be able to catch a lot of bezoar and dog treasures in the bellies of these officials in Qiongzhou Prefecture!
When I opened it and took a look, I immediately became cold. It turned out that this was a comparison table. Each page of the account book was divided into two columns. The upper part was the code name of the person mentioned, but the name below was a meaningless three-character combination.
Judging from the weirdness of it, there is no way it could be a human name.
"Damn, this Gou Er is really a ghost! This is probably another code or something!"
Mu Min thought this was probably a kind of password, but she knew nothing about it. After searching the personnel database through the computer, they found the password person: Zhang Xingpei.
Zhang Xingpei had just returned from Guangzhou and was enjoying his vacation. He received an excellent reception in Guangzhou: he played with four or five women at once. He was exhausted. After returning to Lingao, he only thought about cultivating himself. But a phone call
He summoned the General Administration of Political Security.
Zhang Xingpei was uneasy and thought several times whether he had ever felt sorry for the Cross Travel Group. Could it be that his "life style" in Guangzhou had been reported? It seems that the Political Security Bureau doesn't care about such lower body matters...
After much deliberation, I couldn't think of anything, so I had no choice but to come and report.
"Look at these things, are they passwords?" Lin Baiguang got straight to the point.
Zhang Xingpei has a strong interest in cryptography and information science, and has even 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 cryptography, he was shocked - his cryptography
Almost all of the examples above are based on the West. He has no idea what ancient Chinese codes were like.
"This is very difficult. I know nothing about ancient Chinese codes..." Zhang Xingpei hesitated, "The ancients probably wouldn't have used too complex codes, but it would be difficult to get started without knowing the system inside."
"The principle should be the same, right?"
"It's hard to say." Zhang Xingpei said, "China has 800 commonly used characters, while Westerners' system only has dozens of letters. From a coding perspective, letters are obviously much easier than square characters."
The huge difference in writing between China and the West has resulted in completely different concepts in secret transmission of information. In ancient China, more incisions and lingo were used. Zhang Xingpei knew a little about this kind of incision argot, and it was basically passed down orally, and
Passwords are not the same thing at all.
"Hurry up and call Luo Duo and ask him to check the ancient Chinese code information!"
"It's the middle of the night, it's unethical to disturb others in the middle of the night -" Zhang Xingpei was already very dissatisfied with being summoned late at night, so he used the topic to play off the topic.
"Don't worry, these two bookcases must be in the office of the Ministry of Social Work." Lin Baiguang was obviously not interested in public ethics, and he was very familiar with Luo Duo's habits - his biggest hobby was to collect information, and he became more energetic at night.
good.
But Luo Duo, who was called, could not provide any more information - it was midnight, and he could not go to the computer center of the big library to search. According to his limited memory, Zhang Xingpei generally knew that the main military codes of ancient China were
Two types: one is a "lingo" similar to the "cut" in Jianghu, but how this lingo is used is now unclear.
There is also the so-called "word examination". That is, various situations that may be encountered in the army are compiled into forty items, such as: "Ask for bows", "Ask for arrows", "Ask for march", "Ask for reinforcements"
"And so on. Then the two parties agreed to use a five-character poem with no repeated words as the "word test". When writing the attributes, the item number of the thing to be reported corresponds to the number of words in the poem, and then in the letter
Just add a word "Excellent" next to it. In this way, even if the letter falls into the hands of the enemy, the enemy will know this method. As long as the album with the item number is not leaked, even knowing which poem it is is of no use.
"...But this method is mainly used for communication. If Gou Er only uses it to prevent leaks, it is hard to say whether it is this kind of method."
"Actually, words represent meanings, interesting, 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 very similar to modern ciphers, but judging from the complexity he said, no one thought that Gou Er would use it so complicated.
system. In fact, this password was only used among the Qi Jiajun for a short time and was not promoted and spread.
Zhang Xingpei took a pen and copied down the entire account book. One thing is certain now: these three-character words that he didn't know why were all referring to people's names. He took the 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 the Caesar cipher, but the principle is similar." Zhang Xingpei explained: The so-called Caesar cipher is to replace each letter in the plaintext with a different letter or symbol. According to records: Caesar is simply
Replace each letter in the plaintext with the 3-digit letter following it.
"But this is unlikely." Luo Duo immediately put forward the meaning, "How many letters are there? There are more than 800 commonly used Chinese characters. How big is this character list? Gou Er has to carry a code book with him at all times.
Such a thick code book."
"I don't know 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 personal names, the first character of the three-character word must be the surname. Since it is the surname, there is a question of frequency. Just as the most common letter in the English alphabet is e, Chinese surnames
They also appear frequently. Wang, Zhang, Li, and Chen are the most common surnames. Although Zhang Xingpei doesn't know the order of the number of surnames in the Ming Dynasty, he thinks they should be very modern and there won't be much difference.
"You have to consider local characteristics." Luo Duo reminded him, "For Lingao, the surname Fu is the common surname. There are many immigrants from Fujian here, and there are also many surnames Lin."
"That's the difficulty," Zhang Xingpei said. He singled out the characters with the most frequent surnames and looked at them over and over again, but he just couldn't get started.
"What a tragedy, I have no idea about ancient Chinese books," Zhang Xingpei said in frustration. "What Gou Er used must be an ancient book. And it's very common - just like Europeans like to use the Bible as code words.
The table is the same."
"I think I have guessed one." Mu Min suddenly spoke, "The person who went to tell Wu Mingjin about Gou Er's son Guan must be Wang Zhaomin - his master!"
Everyone's eyes turned to her.
"You see, the first character of the three characters corresponding to Lan Lingweng is exactly the most frequent characters found by Zhang Xingpei: Wang, Zhang, Li, Chen, plus Fu Helin, think about it
Look, there is only one trusted person around Wu Mingjin, or someone he can talk to, who fits these surnames: Wang Zhaomin!"
"Not bad, not bad," Lin Baiguang nodded repeatedly. After comparing it with the information, he no longer felt that it was too unfamiliar.
"Comparing it with his bribery record and the social situation of Lingao we have, we should be able to find out the names of many people - fortunately, these are just names, so 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, the names of several more people were found from clues.
"However, the accuracy of just relying on this guess is still limited, and once Lingao comes out, this method will no longer be accurate." Mu Min said, "We still need to find the word list."
"Let me find it slowly," Zhang Xingpei said. "Now that I know a few characters, I can guess them. Let me start with the most popular surnames of hundreds of families, the Three-Character Classic, and the Thousand-Character Classic to find out - these three
Anyone who has read books in the Ming Dynasty can memorize it."
