"It's a reversed segmented digital encryption method, and fortunately I have a lot of computing power, otherwise I wouldn't have been able to crack it."

The Americans use the latest development of encryption technology, this technology is done with the help of computers, they call it "hyper-vector encryption technology", where "hyper-vector" means "more than the maximum amount of computing of the human brain", even if it is a computer, it is very difficult to crack, because it also adds elements with reverse thinking, not to mention the human brain.

After technical demonstration, the Americans believe that this encryption method is absolutely safe and reliable, and from the current level of technology, there is no possibility of being cracked at least within five years.

But what they didn't expect was that there are still people like Liu Fang in the world, Liu Fang not only has extremely terrifying computing power, but also has a way of thinking that is different from ordinary people, so of course, Liu Fang became the first person in the world to successfully crack this encryption method.

Now that the crack has been successful, the next thing to do is to arrange the English letters and symbols in the correct order according to the cracked results.

The task was much easier for Liu Fang, who did not have much effort to match the numbers of each segment with the letters and symbols of each segment, followed by sorting, which lasted less than ten minutes.

After the reordering work was completed, Liu Fang looked at the full three-page homework book that had been transcribed, and a series of question marks popped up in his head: "This ...... What the hell is this? ”

After rearranging, Liu Fang still saw a chaotic combination of letters and symbols, he didn't know that this was the programming language used by computers, and after analyzing it for a long time, he didn't find any patterns.

After staying for a while, Liu Fang said to himself: "This may be a special symbol used by spies, and it needs to be compared with specific information to get the correct result." ”

There are many ways to encrypt spies, the most common is code, for example, you are given the number 1355, this number may be related to a certain book, the first 13 is the page number, and the last 55 is the 55th text of the page record, so that you can get a text based on this number.

This encryption method is directional, and irrelevant people will naturally have no clue when they see it.

Liu Fang felt that what he lacked was directionality, and he didn't know what the correctly sorted letters and symbols corresponded to, so of course, he couldn't continue to crack them.

"Tick-tick-tick-tick-"

The sound of Morse code came from the military radio again, and Liu Fang's eyes lit up: "Maybe if you have more information, you can see the way, well, keep working!" ”

American Computer Security Center, Michelle argued with IBM's engineers, gradually calmed down, and said in a deep voice: "Since you think that there is no problem with the decoder you produce, then let's conduct another verification, hoping that this verification can prove that what you said is correct, otherwise, the military can only explain it yourself." ”

"No problem, we'll start verifying it now, as long as there is a problem with our machine, the military will personally lobby for it."

The second test began, and soon, the radio message was transmitted through the superposition of high frequencies, and at a propagation speed of near the speed of light, the receiving station at the RB received this information instantly.

The results showed that the receiving station could not decipher this message, and Michelle said to the people at IBM with a blushing face: "Rogson, you saw it with your own eyes, but I didn't mean to find fault, you should know what to do next, right?" ”

Rogson wiped the cold sweat on his forehead, according to the problems presented by the experiment, Rogson knew that most of the problems were the machines produced by his own company, before he was just shirking responsibility, but now the situation is clear at a glance, and he can't shirk it if he wants to.

"Mr. Michelle, please rest assured, I will contact the technical staff to analyze and study the problem, and I will call General Jason personally."

"That's good, I'm tired, I want to go and take a break, so I won't accompany me."

After Michelle finished speaking, he turned his head and left, and Rogson sighed: "This is the fifth failure, if it really doesn't work, I can only propose to the company to withdraw from this business." ”

As the business director of IBM, Rogson knows that the military's money is easy to make, but at the same time it is not so easy to earn, and when you encounter a relatively easy order, making the army's money is almost like robbing a bank, but if you encounter a technically difficult order, the scientific research fee alone can make you lose to death.

When Rogson was sighing, Liu Fang was also sighing: "The second paragraph of information is exactly the same as before, all of which are chaotic letters and symbols, how can people crack it." ”

Liu Fang looked at the sky outside through the crack in the door, and then said: "There is still some time before dawn, forget it, I won't bother with this, let's study the equipment." ”

In the next two hours, Liu Fang carefully debugged and studied the equipment, and at more than four o'clock in the morning, he quietly slipped back to the transformer before dawn and unplugged the wires that had been connected before.

Before going to bed, Liu Fang said to himself: "I don't know if the hellboy will appear on time?" This is the best time for me to get in touch with the high-end knowledge system, and I hope he will keep his word, otherwise I will quit the association and try my luck elsewhere. ”

At the same time, Sam, who was drinking coffee, put down his cup, he looked at the sun outside the window, sighed and said: "I hope the poor boy can show up on time as agreed, otherwise Professor Callem will consider disbanding the association again, where can a computer compare to a radio?" People nowadays are too unfocused. ”

Liu Fang and Sam did not miss the appointment, the next two years, this civilian channel has simply become a special channel for remote teaching, Liu Fang used these two years, constantly absorbing the world's most cutting-edge knowledge of radio knowledge, and has made great progress in radio knowledge.

In this way, Liu Fang continues to absorb the world's most cutting-edge knowledge of radio knowledge, and now Liu Fang is ten years old, he has grown a little taller than before, but his figure has not changed much, and he is still so thin.

Two years later, in the middle of summer, Liu Fang was about to chat with Sam as usual, but Sam said something like this: "Poor boy, I have graduated, and I am about to join the work, I may not have time to speak in the future, the president is old, and he has no energy to continue to manage the association, alas, it seems that the association still avoids the fate of not disbanding." ”
