Chapter 442: Migrating to the Australian Continent? Daming human encryption method
"What? I heard that it had been tried in Changsha and Jinan for a few days, but it was immediately stopped. β
"That's just a pilot. This is an unprecedented war, and it is not a small fight, but must mobilize the strength of the whole country. β
For the inevitable wartime economy and rationing system in the future, Xia Xiaoshi was somewhat reluctant.
Although as the family members of the powerful people of the Ming Dynasty, even if these policies are implemented, they will not affect the standard of living much, but in the final analysis, they are not as calm and reassuring as usual.
"Alas, you beat me, I beat you, I don't know when this kind of dispute will end."
"There is no end, there will be contradictions where there are differences, and there will be conflicts where there are contradictions."
Xia Xiaoshi rested her elbows on the table, holding her chin and looking at Zhou Changfeng, "It would be good if the imperial court stopped after pacifying the South Seas, and simply drove the British and Dutch away, and then they could live in peace, and they couldn't go all the way to Australia." β
The latter took a sip of tea and found that it was a little hot, so he put the cup down, "How to say, from a macro point of view, only by completely seizing Australia can we better reverse the difficulties that our country will face in the future." β
He shrugged his shoulders and said eloquently:
"The last time the population was counted was more than 60,000, and now... Let's count it at 70,000, and the population will go up in the future, and it is certain that it will exceed 100,000. β
"With such a large population base, the productivity and welfare advantages brought by industrial construction will be greatly diluted, and the difficulty of governance is very, very high, and it is difficult to achieve a good and healthy level."
"Steel, for example, is only a pitiful thirty-six pounds per capita. And even Italy, which has the weakest comprehensive national strength, has only one-sixth of its steel production in the Ming Dynasty, and its per capita is three times that of ours. β
"So even if you occupy oil resources or an important strait gateway like Malacca, and sit and collect money, the benefits will be diluted very small."
"Although some people are purely greedy, there are still many people in the government and the opposition who want to try to cure the root cause. Listing Australia as a goal is promising and promising, and it is naturally worth trying to strive for. β
Xia Xiaoshi, who looked calm, nodded slowly and blinked, "Are you going to move a large number of people in the future?" Maybe it will take tens of thousands of people to move to make it work, right? Is there enough land in Australia to support so many people? β
"I have had a rough discussion with the emperor before, and they all have different views, some say that it is enough to maintain 50,000 in the local area, and some people say that 70,000 is the best." Zhou Changfeng said disapprehantly: "Australia doesn't care, that place should be developed well, and it will not be a problem to raise one or two thousand people." β
Although the Australian continent is vast, two-thirds of the land area is unsuitable for human habitation, and the remaining suitable area is about 2.5 million square kilometers.
However, Australia's geographical conditions are average, and the carrying capacity per unit area of land is low.
Although the topographical features seem to be similar to those of northwest China, Australia has no snow-capped mountains and no snowfall, and its water resources are basically replenished by rainwater. Moreover, because it is located in tropical and subtropical regions, there is a large amount of water evaporation, and there is a lack of abundant water resources.
At the same time, it is the oldest continent in the world, which has endured long-term erosion, barren land and poor arable land fertility.
Therefore, it is estimated that Australia can only carry 200 million people, and any more resources will be tight.
"How's that going for Jian Jian? Look at it. β
"Okay, it's a special way to make a fuss, and when she's tired, she falls asleep, and this girl is especially active."
Xia Xiaoshi is very nerve-wracking for her daughter, she doesn't cry much, it seems to be very worry-free, but she is extremely active, crawling, crawling, rolling, rolling.
"I was good when I was a child, Zhou Kexing, it must be that you loved to make trouble when you were a child!"
Hearing her claim that she was very well-behaved when she was a child, and it was quite worry-free not to cry or make trouble, Zhou Changfeng recalled the words she used to talk with her father-in-law while fishing.
He said leisurely: "However, Taishan, his old man told me that it is completely different from what you told me, he said that you have crawled and fallen out of bed several times, and then you cried...... Very short of memory, lack of heart. β
"Ahhh Miss by a mile! β
Xia Xiaoshi insisted that Xia Bing was fooling him, and then the two began to quarrel, which then evolved into flirting.
It was late in the evening, but it was already dark in November, and it was almost an hour before the meal.
Zhou Changfeng looked at his panting wife, and suddenly thought about it, so he reached out and pulled her to the living room on the second floor.
"Hey, what's the matter?"
"I suddenly thought of something very important, and I'll tell you about it in the room."
"Huh?" Xia Xiaoshi, who didn't know why, was stunned and said, "Is there something wrong?" β
"Sort of." Zhou Changfeng pretended to be serious and replied, "It's a big deal for you and me. β
Then, inevitably, there was a long drought and rain after many days of separation.
~
Although the emperor asked for a detailed argument on the strategic deployment, Zhou Changfeng thought about it and found that the meeting held the day after tomorrow had little to do with him, and he was mainly responsible for putting forward tactical opinions.
Since it's a tactical matter, what is there to prepare? As a skilled tactician, I have long been in my heart.
So he didn't bother with the logistical and political implications of landing in Cairns and Townsville, and rushed to the Metropolitan Governor's Telecommunications Office early the next morning.
The Telecommunications Department has a mysterious subordinate organization, codenamed "Dongshaojian", which is a small but elite group of people who are behind the production and control of the communication keys of the million-dollar Ming army.
Walking between the offices of the Metropolitan Governor's Office, there are soldiers of different heights, short, fat and thin, military and civilian, male and female......
Walking through a forest of bleak leaves on the blue brick path, you will see a small two-story building on the top of a hanging hill.
There was a water tower a few dozen meters away, but Zhou Changfeng intuitively thought that there might be a sentry on it.
"That's it, please come in."
Even in the old-fashioned army, those veterans who are unscrupulous do not dare to be too presumptuous when they see officers, at least wear their hats, straighten their collars, and simply stand up straight and salute decisively.
Therefore, Zhou Changfeng's first impression of this place was that it was really subordinate to the Metropolitan Governor's Mansion?
The room was warm because of the stove, but the furnishings were disheveled, the tables and chairs were crooked, and half of the young people had unkempt hair and disheveled clothes.
The lieutenant colonel who came with him explained in a low voice: "Don't be surprised, the people in this... The temperament is somewhat weird.,When I'm in the mood for work, I don't stop for days.,Sometimes at the end of the day, I drink a few cups of tea.γEat two mouthfuls of cakes.,Grooming or something naturally doesn't take care of it.γ β
Most people are working hard, but there are a few who seem to be idle.
"Who... Yan Yuansong, you are very idle today, you are still reading the newspaper while eating, come here. β
A young man who looked emaciated and listless put down the paper bag of oil cakes, then got up and walked over.
Compared to the fact that someone next to him even hung his military uniform and shirt on the side and only wore his underwear, he at least put his military uniform neatly. Look at the rank, this is a civilian major.
"Zhi Yan Yuansong, I've seen the chief! Unexpectedly, it was Zhou Zhizhao who came in person. β
"The next confrontation is imminent, although our army now has the initiative advantage, but still can not relax, I came this time mainly to learn about the situation of telecommunications encryption."
In order not to disturb the work of others, the group went to a cubicle next to the office.
Daming attaches great importance to telecommunications encryption, in addition to the objective inevitable factors, there are also reasons for the loss of long memory.
In the late year of the Zhezong Dynasty, in the battle of the Ming Dynasty, the Ming army suffered a big loss because the code was deciphered.
At that time, the imperial court used a very simple encryption method - fixed addition and subtraction of the numerical code corresponding to each Chinese character, so it was easy to decipher; Although the encryption numbers of the Lu division and the water division are different, they can be consistent with the laws of the imperial court, so it will be all over in a few days.
ββ¦β¦ For example, 'I like newyork' is shifted to 'L iiek enwoyrk' which is a bit difficult to read, while 'I like kyork' becomes 'I like Jingshi Tianfu' becomes almost ineffective. β
"In addition, Chinese character messages are completely based on the original code, after all, there are only 26 letters in English, only 30 in German, and there are more than 2,000 Chinese characters even in common words."
Western alphabets only need to specify the encoding of twenty or thirty letters, while Chinese characters cannot always encode thousands of characters, so Chinese characters will be converted into numbers first, and then transmitted.
For example, "And" is 0011, "Lane" is 1702, and "An" is 1344.

After the Western powers popularized the use of cipher machines for encryption, the Ministry of Foreign Affairs of the Ministry of Rites also specially purchased and tested it, but both the Ministry of Foreign Affairs and the Ministry of Military Affairs were not satisfied with it and were skeptical of its encryption capabilities.
This mechanical cipher machine is advertised as having "almost no chance of being deciphered", as there are as many as one trillion possibilities for the results of its permutations.
But in fact, it is still possible to decipher and decipher its telecommunications through some ingenious technical means, and the test team of Dongjiama estimates that it can complete about one-ninth of the content interpretation in half a month; If the other party communicates frequently and the content is long, then the efficiency of interpretation will increase.
"So......" Zhou Changfeng said thoughtfully, "So is the telecommunications encryption used by the current dynasty highly reliable?" β
Without waiting for Yan Yuansong to answer, the lieutenant colonel smiled and said, "Zhou Zhizhao, if the reliability is low, how can it be used?" β
However, Yan Yuansong said quite seriously: "There is no absoluteness in everything, Chief Zhou, the position can only be said to be generally reliable, and it is very difficult to decipher, but it must still be replaced regularly, and the longest should not exceed six months." β
Decipherment is not a complete decipherment, and in fact it is rare to do so, but as little as a fraction of an important telegram is deciphered, it can reveal a great deal of useful information.
The Ming Navy uses a variety of ciphers, and the low-level ciphers are only used in tactical communications, which is of little significance, because in this case, it may even be possible to directly use the clear code to send reports in order to race against time.
The high-level password is used for up and down communication commands, taking "the wounded Zhou Changfeng took a plane to the station of the 1st Marine Brigade" as an example, and the encryption steps are as follows:
The first step is to convert special nouns into codes, which are 220, 301, and 765 for the perimeter wind, and 2718, 0230, and 5552 for the 1st Marine Brigade.
When used, it is completely disrupted, the circumference wind of the first row is 220, and the second line may be 765.
The second step is to add a random additional number 331 to the code, so that 220 will become 551 and 2718 will become 3049.
The third step is to turn the rest of the words into numbers through the codebook, and finally get a large number of numbers.
The fourth step is to find the word that appears most frequently in the whole telegram and replace it with black or dialect at will, for example, if "injured" appears the most, then replace the "injured" in a certain paragraph with "hung red" at will.
Thus confusing the judgment of the enemy - the more frequent the word, the easier it is to become a breakthrough.
In order to further increase the difficulty of deciphering, three codebooks will be issued for each update: copy A, copy B, and spare copy.
On odd-numbered days such as 1357, copy A is used, and on even-numbered days such as 2468, copy B is used, so that the content of telecommunications intercepted by the enemy is equal to halved, and it is more and more difficult to find patterns.
Compared with the more versatile, convenient and efficient cipher machine, this set of encryption methods adopted by the Ming Navy is very cumbersome and inefficient, and can even be said to be a bit primitive.
When the mechanical alphabet cipher machine is used, it will be automatically encrypted as long as the input content is entered, but this set of operations basically relies on manpower, and encrypted sending and receiving and reading are quite time-consuming and laborious.
Even the most skilled translators can encrypt and decipher more than a dozen times slower than cipher machines.
Of course, the difficulty of deciphering and deciphering telecommunications obtained by this set of encryption methods is relatively high.
In contrast, the Japanese historically converted Japanese into Japanese Romaji, which was then encrypted by an imitation of the 91-style cipher machine.
In addition to the commercial model Enigma cipher machine, the technical source of the 91-style cipher machine is from the Swedish Haglin company, but because the Swedes knew that the Japanese were only here to steal the technology and would not buy it in large quantities, they sent these poor ghosts away with a simple and low-profile version.

Zhou Changfeng nodded, "Okay, in this case, I can rest assured, but I still can't be careless, and frequent replacement is the safest." β
Just as he was about to leave, a question suddenly came to his mind.
"By the way, how did you decipher the American code?"
Yan Yuansong didn't care, and said lightly: "The diplomatic code is easy to interpret, and the 'gray' diplomatic code was completely cracked a few years ago." β
Zhou Changfeng pointed around, "Then these are ......"
"The communications messages of the US Navy intercepted by various radio listening groups are all summarized here."
"Shhh...... How's it going? β
"I've been busy for more than half a month, and I've just started to improve, so I guess I can have a small breakthrough in a few days."
"Didn't you get any useful information out of it?" Looking at the pile of manuscript paper around him, Zhou Changfeng was a little disappointed.
"Only some words that appear more frequently are more certain, uh......" Yan Yuansong hesitated for a few seconds, and then said: "At the moment, it is generally certain that the aircraft carrier Lexington, it seems to have gone to sea." β
"Aha? Is it just an aircraft carrier? β
