[69 Book Bar-www.] Chapter 51: When the information is flowing smoothly and the attack is launched
The specific appointments are as follows: Tan Yurao is appointed as the team leader, and mathematics professor Luo Yubin is appointed as the director of the black room.
Lin Ke is appointed as the captain of the monitoring team, and Xiao Bin is appointed as the captain of the student team.
Dongfang Yu serves as the director of the analysis room.
The monitoring team has copied hundreds of messages and handed them all to the message analysis room.
Together with the code books obtained from previous gunshots, they were sorted and handed over to the black room for deduction.
The busiest people are the people in the dark room.
Fortunately, among the items Xiaolong robbed were several 18-bit robotic computers, which greatly reduced the calculation workload.
"Hehehe - you really have everything here. Hand-cranked computers, Enigma cipher machines. What else do you have? Take them out. Let's take a look - you are really powerful. The National Army
None of them can compare to you."
Xiao Wu first gave everyone some advice on the mathematical problems of passwords.
From the origin of branches of cryptographic mathematics to the same destination in modern cryptographic mathematics.
From the higher-order function theory of cryptographic mathematics; such as the Neumann function of the second type of Bessel to the Hankel function of the third type.
Until the mutated Bessel function of the fusion of each function.
Error theory and experimental data processing, optimization method and mutual mutation and crossover of matrices, etc.
No need to use manuscripts or read books, just pick them up at your fingertips and talk eloquently.
The mathematical formulas on the blackboard are like a treasure house of mathematics. In front of everyone, the starry night sky in the field of mathematics is displayed, which is so brilliant and so profound.
There are both black holes and white holes. There are also splendid mathematical stars. A group of people are like floating in a mathematical garden, lingering and obsessed with it, unwilling to come out.
Not only has he explored the field of mathematics, Xiao Wu also analyzed the mechanical principles of the cipher machine based on his own research on the mathematical viewpoint of mechanical theory and combined with the structure of the cipher machine.
Mathematical theory for the realization of mechanical principles.
Various, rigorous logical reasoning, and reasonable interlocking.
These people were surrounded by one Buddha who was born and two Buddhas who ascended to heaven. It took almost a month to make amends.
But it is recognized by everyone.
This time it was so worth it.
And that master would expand everyone's mathematical horizons in this way.
All secrets were disclosed selflessly.
This is a pinnacle that the Harvard Institute of Mathematics in the United States cannot reach at all.
There is no sharing of friendship at all, not even a little bit.
The mathematical theory of cryptography explained here, any paragraph of it, can be said to be the pinnacle conclusion in the field of cryptography theory.
Enough to subvert any existing
Several people kept spinning day and night. You lay down when you were sleepy, and I got up again. You passed out, and I woke up again.
Sometimes dancing wildly, sometimes sinking, more than ten days have passed, and a lot of wood has been consumed. Several carpenters followed the scouts, dismantling and building, but the scraps they threw away could not be burned.
Two of the cipher machines were also dismantled, and their corpses were scattered all over the floor.
But with a door cipher madman like Xiao Wu, a mathematical genius like Luo Yubin, a nimble and agile thinker like Tan Yurao, and a meticulous and comprehensive operation like Dongfang Yu, this team is the world's best combination of cryptography researchers. There is no difficulty that they can't overcome.
.
The three people who graduated from the Mathematics Department of Peking University were sincerely impressed by Xiao Wu's profound mathematical background and sophisticated logical thinking ability. They were also surprised that he actually owned an original German Enigma cipher machine. This film
Even in Germany, the machine is extremely rare to see. It can only be seen in the German intelligence agency.
Finally, a month later, based on a large number of Japanese military messages, the black room deciphered the code of the Japanese blue-light cipher machine and copied the original blue-light cipher machine used by the Japanese army.
The Japanese army's code is no longer a problem.
Suddenly the future became bright in the eyes of everyone.
Everyone has benefited greatly from this research.
But no one else knows what these later people do every day.
Just seeing Xiaolong was very fond of their treasure.
The protective measures are extremely strict.
It is strictly forbidden for unrelated people to enter the residence.
Otherwise, you can just shoot without saying hello and kill without mercy.
The emergence of imitation cipher machines also relied on the precision processing capabilities of the instrument machine tools Xiaolong bought.
And the exquisite craftsmanship of the two masters.
The base began to copy a large number of Japanese blue-ray cipher machines, which made a huge contribution to the Anti-Japanese War.
The blue-ray cipher machine that the Japanese army is proud of has a seven-toothed cipher key, but the two behind them are very simple. Maybe they didn’t dare to make it too complicated, or maybe they couldn’t conquer it.
Difficult problems in mathematics.
But there are already millions of variations.
But there are still loopholes left that can be cracked. This makes them extremely arrogant.
He actually took it out and used it openly.
As a large number of Japanese military messages were deciphered, the deployment of Japanese troops, signs of activities, and mobilization plans became clear at a glance.
Tan Yurao also shared the results and passed them on to her sister in a timely manner through the contact point in Sandaojiang.
It also includes a large amount of information on the activities of the Anti-League, all of which are under control.
Xiaolong also allocated a large amount of communication equipment to Xiaowu to equip his intelligence network.
At the same time, Xiaowu was told that a large number of educated young people should be recruited to the base for training to enrich the electronics brigade.
There is still a shortage of people.
It felt like there was not enough manpower.
Xiaowu had to rush back to Harbin to take charge of the work.
Can't the three armies be left without a master for a day?
Xiaowu's departure is very regrettable for everyone.
After all, love grows over time.
Besides, Okazaki Brigade's encirclement and suppression army just went back. Xiaolong waited until June, during which time he was busy with the radio station.
Still no movement was found in the Japanese base camp, so they decided to fight outside to confuse the Japanese.
Once you have information, you will have eyes and your mind will be bright. This way you will have a foundation for fighting.
Xiaolong immediately marked all enemies on the map.
Facing the daily enemy situation on the map, Xiaolong felt a sense of fear in his heart.
At that time, they attacked the Japanese army blindly.
Duoxuan fell into the trap of the Japanese army.
Look at the railway network and highway network all over the place.
Xiaolong was anxious.
How to break the hinges of the Japanese army?
Halong held the second operational meeting.
Study future combat directions.
The brothers and the captain of the electronics brigade, Tan Yurao, sat down together.
Xiaolong said,
"It is said that when fighting a war, one must have the right time, the right place, the right people, and the right people. This is also the saying left by our ancestors. What I am going to talk about today is the current situation. Look at this map.
At this time, in the Northeast, especially in the North Manchuria region in the north of China, we are here.
Severe cold temperatures of -30 to 40 degrees below zero are very common in winter, and can also occur at 50 degrees. This kind of extremely cold weather is never seen in Guanhai."
"The winter weather in Guanhai is far less cold than in the Northeast. In the Northeast, if you don't have cotton-padded clothes, or even thick cotton-padded clothes, you are asking for suicide. Needless to say, even the cold will freeze us to pieces.
