Chapter 679 Flying pigeons biography, simple and practical ciphertext
The temporary residence for Xiao Tang and his close brothers in Tongtian County, Weishengjun, was a courtyard not far from the north gate of the county. Originally, this mansion was owned by a wealthy family, but after the banditry in Hedong, this place
The owner then took the whole family to a clan relative's house on Hebei West Road to escape the trouble, leaving only an old steward to guard the house.
In order to make Xiao Tang live comfortably in the county, Magistrate Gong and Lieutenant Li of Tongdan County asked the government officials to inform the stewards of the mansion to clean up the house inside and outside, and then invited Xiao Tang, Xiao Jiasui, Hua Rong, Wang
Jin and others moved in. In the past, the wealthy residents of this mansion had to rely on the county government office to take care of them, so the old steward also agreed. However, after Xiao Tang stayed here temporarily, he politely declined and Magistrate Gong wanted to stay again.
With the kindness of looking for some maids and servants to serve him, except for Qiong Ying, mother and daughter, and Ye Qing and his wife, almost all the people in this mansion are close to him who know that Xiao Tang is working on both sides of the government and Lu Lin.
After all, Xiao and Tang now need to rely on flying pigeons to send letters to Baozhou in Liaodong, Ershan in Qingzhou, several cottages on South Jingxi Road, Xiaojiaji in Damingfu, Banqiao Town in Mizhou, and even Baiyun on Liangzhe Road, which is currently undergoing resettlement planning.
Mountains, Fujian Road, Wuyi Mountain and other places communicate with each other. However, Xiao Tang's leaders who work in various places in the green forest also need to set up pigeon houses locally so that the homing pigeons that have been trained and can recognize their nests can accurately reach their destinations.
However, Xiao Tang currently has no base in Hedong for him to plan various matters in the green forest. What's more, he is acting in the capacity of a government official, and there are many people around him. In the past few days, he had no way to get in touch with his confidants who were elsewhere.
Contact. Shi Xiu came on this trip not only to help Xiao Tang in his campaign, but also among the people who came with him to Tongdan County, there were also some who were carrying a few to deliver letters to Bianliang in Tokyo.
Carrier pigeon, now in the Xiao Mansion in Bianjing, Yang Xu, Yan Qing and other brothers will receive the letter with Xiao Tang's secret order and then convey it to everyone. This move will be more secure and secretive.
In ancient times, in order to transmit encrypted official documents or letters, methods such as word splitting and argot were used. According to legend, the earliest encrypted military intelligence transmission in Chinese history was the chief conspirator of King Wu's conquest of Zhou and the founding father of the Zhou Dynasty for 800 years.
, he used copper plates and bamboo plates to make surface-engraved patterns, and the orders divided into two were called Yin symbols. Depending on the length of the Yin symbols, they represented various military orders secretly promulgated and various battlefield secrets conveyed. Then Jiang Ziya
The "Yin Shu" was also created. All conspiracies and plans were conveyed to the generals outside in Yin Shu. The Yin Shu usually sent three people to deliver the letter. Each letter only contained part of the secret order and was inconsistent with each other. The person who sent the letter did not know all the letters.
Content, with this arrangement, even if the enemy intercepts a letter, it will not be able to see through one's own conspiracy.
In the Song Dynasty, the Song Army adopted the rule of keeping military communications confidential. According to the records in the "Wu Jing Zong Yao", a five-character poem of about forty characters was randomly selected as the decryption code, but the words in the poem were not allowed to be repeated.
The two parties who exchanged messages compiled a codebook of 40 phrases in advance. Each word in the poem corresponded to a phrase. The order of the phrases was temporarily randomly arranged. At the same time, numbers were marked on ordinary official documents. The party who received the secret order then
You can compare the numbers on the decrypted key book and official documents to interpret information such as requests for support, enemy movements, material requirements, etc.
Xiao Tang's plan in the green forest was of great importance and must not be leaked. He also thought about using alum water to write his words in a confidential letter that would be invisible when water dries but only visible when wet.
Although passing letters was not very popular in the Song Dynasty, some people were good at using this method among the people. For example, in the "Three Dynasties Beimeng Huibian" written by Xu Mengxin of the Southern Song Dynasty, it was recorded that Song Qinzong Zhao
Huan then learned that writing on silk can only be seen after entering the water, so the Jin army besieged Bianjing. He used the writing on silk as an edict and issued an order to summon generals from all walks of life to lead their troops to rescue them.
In other words, even if Xiao Tang wrote the secret order in alum water and then delivered it by carrier pigeon, it would still be intercepted and there would still be a risk that the entire plan would be exposed.
Xiao Tang also thought about trying to use the reverse code created by Qi Jiguang, the famous anti-Japanese general of the Ming Dynasty, as a means of transmitting secret commands. However, how to use the initial consonants of the upper letter and the final rhyme of the lower letter to cut out the pronunciation of another word? As Xiao Tang recorded
Secondly, this method also involves the use of eight tones of local dialect sounds, so if it is implemented, it will be half the result with twice the result. After Xiao Tang thought hard for a long time, an idea suddenly flashed in his mind, and he couldn't help but laugh loudly. Because
Xiao Tang later discovered that he was also familiar with a kind of "secret text" that was very simple and the content of which could not be guessed by others. He was used to the life in the Song Dynasty, so for a while he did not think of the kind of "secret text" that was used to convey messages.
A method that can achieve absolute confidentiality.
The method Xiao Tang thought of was Pinyin.
In ancient China, there was no pinyin alphabet, but the straight or reverse method was used to notate Chinese characters. Since the Qingyin movement began in the late Qing Dynasty, later generations have successively tried to use the Latin alphabet and its variants, or the Beiyang government issued the
The characters are Chinese characters that indicate the pronunciation (now widely used in Taiwan, China). The Chinese pinyin commonly used in later generations was created by the "Pinyin Plan Committee" established by the Chinese Character Reform Commission in 1955, and was therefore made of alum.
Water is written in pinyin as the content of the secret message. Even if it is intercepted by someone, who in the Song Dynasty can understand the Latin alphabet at this time?
Then Xiao Tang ordered Yan Qing, Shi Xiu, Shi Qian, Xiao Yi and others, as well as two or three close confidants selected from various places under his command, to identify the pinyin and first use the straight pronunciation to assist it. It didn't take long for them to be able to pinyin.
I am familiar with the pinyin letters by heart. Although there is a big difference between the Mandarin of the Song Dynasty and the Chinese of later generations, using pinyin can still roughly let the other party know the content of the "secret text". So now Xiao and Tang use flying pigeons to send letters to communicate with various places.
I am also very relieved that using carrier pigeons to transmit information is just because this method of transmitting information is accurate, flexible and not restricted by terrain. Even if Xiao Tang wrote "nimentongtongdoushidashabi" in front of Cai Jing, Tong Guan, Gao Qiu and other powerful traitors,
, who can guess what he wrote?
Here, Shi Xiu had already sent someone to write the cipher text, and he picked another carrier pigeon with smooth feathers, bright color, and gray-white body, except for the gray-black head and tail. The pinyin written in fly head fine writing was tied to the length of its legs.
They left the study and were about to throw out the carrier pigeon and let it fly straight to Xiao Mansion in Bianjing.
At this moment, Shi Xiu suddenly looked at Hua Rong who had just walked into the mansion and said, "Brother Hua Rong, where is Niu Heizi now? Didn't the other generals in the army come with you to visit my brother?"
Hua Rong smiled slightly and said: "Niu Heizi is currently outside the county town helping Coach Wang Jin to select and train soldiers, and Hu Yan is in charge. Guan Dujian and others are also in the county office with Luo Xueyu, and the enemy's widow and her manager are behind. At home, you are surrounded by your confidants, so Saburo can feel at ease."
Shi Xiu nodded and said: "That's good. After all, the big thing my brother is planning involves a sea of blood. Although there won't be any mistakes in delivering the letter with this clever cipher text, it can't be done if you sail a ten thousand year ship carefully. Teach others to see the clues."
After Shi Xiu finished speaking, he threw his arms to the sky again, and the carrier pigeon with the secret message bound to it flew into the sky and flew straight to the south.
However, when Shi Xiu and Hua Rong exchanged a few words and were about to return to the hall to report to Xiao Tang, they suddenly heard a whizzing sound outside the wall, and a flying stone shot into the air, hitting the bird that had just spread its wings. Homing pigeon takes flight.
"Gululu" a pigeon chirped, and the homing pigeon hit the flying stone and immediately fell from the air. Its gray-white feathers were scattered all over the sky.
