"When did you get so much money?" Peng Yi suddenly interjected a sentence, which made Xu Jie, who felt good about himself and was a little proud at the same time, feel very disappointed!

"What do you say, if others don't know, don't you give me money for the things you use and the things you use next door?" Xu Jie said angrily. This is true, whether it is the various light weapons used by the Huaxia Army or the various warships used by the Admiralty next door, they are all from the Re (Baidu) Na (Baidu) Sub-ship and Light Weapons Design Bureau. Well, now it's called the Huayi Ordnance Research Institute. It has headquarters in Italy and China. From rifle pistols at the very beginning to light machine gun mortars later. These things all have Xu Jie's patent fees! There are not many weapons, but the whole of China is using Xu's light weapons, and of course, Italy, Britain and Germany also import a lot. The money made from these things is absolutely astronomical!

"Profiteers. Merchants don't make as much money as you as an office worker, which is faster than robbing a bank. Peng Yi scolded with a smile. At this time, the two who were joking with each other didn't notice that Su Jing's eyes suddenly flashed with a gleam, and a smile appeared on the originally frustrated little face.

"So I want to know, if this encryption machine is procured by the Huaxia government, how much profit will my team and I make?" Su Jing asked calmly. "15% of the sale price is your profit." Xu Jie replied.

"15% selling price? This is too low, and the general patent fee is about 20. I think you know very well the meaning of this kind of encryption machine, and we don't want much. 25% profit, which is already quite reasonable. Su Jing said a little angrily.

"First, the government accepts a 20% royalty, and secondly. Your product is not perfect, and it is even a theoretical machine. You don't know what the military and the government are asking for, and the products you produce don't meet the needs of your customers. So you need to improve this machine now, and that 5% of the profit goes to the people who provide technical improvements for this encryption machine. And that person is me. Xu Jie said with some smugness.

"This gentleman, people's money is a number to a certain extent, you see if you can stop inserting a bar this time. No matter how much money you have, you still plan to build a golden house" Peng Yi on the side interjected without knowing the current affairs.

"Go aside. Let the two little girls brush for more than 1 month, and they didn't understand the principle after the end, and they are still drawing the distribution table. Please, a little new idea, okay? If you can make it, the 5% profit will be given to you! Help you save money and you don't want to. Xu Jie said angrily.

"Straight to the point. Let's start with the problem of your encryption machine. Xu Jie ignored Peng Yi, who was smiling strangely. Xu Jie turned on the encryption machine and pointed to a wrench on it and said, "If I'm not mistaken." This thing is to reset the rotor. Because the length of each piece of information is different, so after the encryption is completed, the position of the entire rotor has been out of order, and the next time you accept the file, it will be completely garbled after encryption, so you have set up this reset handle, which can make the wheel return to some specific positions, and the reason why you can encrypt a telegram into several different ciphertexts is also the reason. Am I right? ”

"That's right, only after deciding on the initial position. The ciphertext typed by the encryptor is meaningful. If it cannot be reset, once the two mechanical rotors of encryption and decryption are not in the same initial position, then the cracking cannot be carried out. Su Jing nodded.

"Miss Su's design is indeed ingenious, but this reset handle is very stupid!" Xu Jie said with some dissatisfaction. "You only have 4 levels of reset handles, which means that there are only four encryption methods. Once the other party gets an encryption machine, after receiving the ciphertext, it will definitely be able to crack the plaintext as long as it experiments four times, which cannot meet the needs of customers at all. The security breach is too big. ”

"But if we don't know the initial position of the rotor of the encryption machine, how can we decrypt it?" Su Jing also knew about this problem, but she never solved this problem.

"We can set an additional triple knob, which is used in conjunction with the encryption machine, and the function is to determine the initial position of the three rotors of the encryption machine. If you think about it, each roulette wheel has 26 letters, so the initial position of the three roulette wheels has as many as 26*26*26, a total of 17,526 possibilities. If you use the experimental method, this is basically impossible to decipher, as for how to determine the position of the rotor of the encryption machine, we can give the receiver a key. The initial position of the three rotors over a period of time is described above. That way, security is a lot better, isn't it? Xu Jie asked with a smile.

"The idea of the key is very good, the decipherment of the password is divided into two parts, the other party lacks the encryption machine or the lack of the key can not be deciphered, and in the same system that uses the encryption machine, if the key is different, even if the same encryption machine is used, then they are insulated from each other, this idea is quite good." Su Jing nodded and said.

"And I noticed that you made the runner part sealed, how to say it, there are advantages and disadvantages, on the one hand, even if the other party seizes it, if you add some self-destruct devices to it, you can't get the cipher machine, but at the same time, it also reduces the encryption ability of the cipher machine, if the runner can be disassembled, then we have 6 times more possibilities, and the other party's decipherment will be more troublesome." Xu Jie continued to add.

"Do you have a more immoral way? This has led to an unimaginable number of experiments. To a general extent, it is impossible for the other party to decipher. Su Jing said with a smile.

"That's not enough, we also need the last layer of insurance, which is the connection line between the keys and the wheel, for example, we can pick 6 letters on the keyboard at a time, and then let them correspond to the 6 positions on the wheel, and then the next time, we change the order of the six letters. In this case, we are hundreds of times more likely. Xu Jie said proudly.

"If the gentleman has such an advanced idea, why not put it into practice? With your position and the resources of the Army, Your Excellency should have been able to develop this encryption machine a long time ago. Ma Xiaoyun asked with some curiosity.

"Didn't I say that when you have time, you don't have money, and when you have money, you need to do more important things." Xu Jie said embarrassedly. "If you can, I hope that Miss Su and your team can join the formation of the Huaxia Government's Information and Communication Confidentiality Department, we need professionals like you. Transform theories into reality. Xu Jie sent out an invitation.

"Is there a department? How do I not know the way? Peng Yi suddenly felt that today's meeting was a little out of direction.

"Premier Xu said yes, naturally there is, but I need to state that I make an encryption machine is just an occasional idea, I majored in electrification and mechanics, let me do this work, I'm afraid it's not suitable. After all, I don't have any understanding of what the military and government require and write passwords. Su Jing said with a smile.

"How do you know that he is Premier Xu's?" Peng Yi asked with wide eyes. It is only today that Peng Yi has expressed doubts about his IQ level. "There are so many smart people in this world." Peng Yi said rather depressedly.

"What Premier Xu said just now is very clear, in the absence of a family background, the Chinese who can earn so much money at the age of only 30 may be Premier Xu alone, right? Especially the sentence that the army and navy are using his products, the warships of our Huaxia Navy and the light weapons of the army are all from the hands of one person, to this extent, if I still don't know who Your Excellency Lu Dao is, then it is too undeserved. Su Jing said proudly.

"Okay, Miss Su, in that case, let's make it clear, I have no interest in the improvement of this encryption machine and the related patent fees. However, the two requirements that can only be provided to the Chinese government and military, and that the leakage of technology is strictly prohibited cannot be changed. In addition, I sincerely ask that Miss Su can work for the Chinese government, and we will give you and your group the benefits obtained from your patents and other inventions. Including my improvement patents. Xu Jie said with a smile.

"Since Premier Xu has said so, the little woman is better to be respectful than to obey her fate." Su Jing is still very satisfied with today's results, on the one hand, the income from her invention has been guaranteed, and on the other hand, as a patriot, she can finally get the support of the government and continue to carry forward this industry, which is also a good choice.

"By the way, I want to ask, Miss Su has research on mechanical manufacturing and electrification?" Xu Jie wanted to be sure again.

"Double Master's Degree from Heisenberg University." Su Jing said proudly. It is not easy to obtain two master's degrees at the same time in this era, and this is also something that Su Jing is very proud of.

"Great, in the near future there will be a large delegation from Germany with professionals in the field of mechanical technology, and I think we are currently short of a technical consultant, and you and your team should be up to the task. In addition, it must be noted that the issue of the encryption machine must not be mentioned to anyone, it is a state secret, and if it is violated, I think General Peng Yi's subordinates will be happy to take this opportunity to declare a personal vendetta. Xu Jie said seriously.

"This is naturally possible, and I would like to ask, the prime minister said that this encryption method can be deciphered, so how to solve it? I hope to give you some advice, and we also need to pay attention to related aspects in our future work. Although Xu Jie proposed many improvements, it was because Xu Jie knew more about the operation of the government and the army, which was an innate advantage, and it could not convince Su Jing, so Su Jing needed to try what level the other party was.
