Reborn Ace Hack

Originally, Xiao Yuan's thinking had been stuck on the isolated analysis of each sample. After trying various methods without success, he had to change his thinking and began to look for new methods. After trying several other methods, he began to

I thought of intercepting a few more sets of data, and then conducting longitudinal analysis on the data with the same sampling rate according to the time period.

After the longitudinal analysis also yielded no results, he put together the data with different sampling rates sampled during the same period and conducted horizontal analysis, but the horizontal analysis also did not yield any useful results.

"Are these waveforms themselves analog signals and have nothing to do with digital signals?" Xiao Yuan couldn't help but have such doubts. If it is really as he suspected, then all the efforts he made before, including the programs he wrote, are all

It's no use.

Although Xiao Yuan knew very well that the probability of signal decryption failure was much greater than the probability of success, Tang Sa's absence for a day made him very worried. He had to help Tang Sa decrypt the signal sent from this signal source as soon as possible. This was his only choice now.

There is nothing he can do to help her, so he is very unwilling to admit failure, and he will not give up just because of this.

Since he is unwilling to give up, he needs to find another way. It is already past six o'clock in the evening. He has only eaten one breakfast a day, but Xiao Yuan does not feel hungry at all. After a day of high-intensity mental work and long hours of staring,

Looking at the CRT monitor of the computer made his eyes sore and sour, but he was completely unaware of this. His eyes were still fixed on the computer screen, thinking about what method he should use to continue trying next.

After a while, he was going to copy these strings onto paper again and analyze them. This time the strings he copied were different from the last single analysis. He was going to put the binary streams obtained at different sampling rates in the same cycle together for horizontal comparison.

analyze.

After copying down a binary string, when Xiao Yuan copied the second string, he copied more than a dozen binary digits, then stopped and temporarily put the previously copied content aside and found it in the file cabinet in the computer room.

On a large piece of white paper, he copied the first string again. This time, because the paper was long enough, he copied the entire binary string into one line, and then copied another string below, and aligned it with the previous string.

The numbers are aligned from high to low, and so on.

Xiao Yuan copied all the binary strings collected in a cycle onto the paper in a digitally aligned manner. At this time, he was originally going to compare and analyze these characters, but when he glanced at the densely packed paper, he copied almost half of the paper.

When he saw the binary string, he suddenly froze. What he saw in front of him made him think that he was dazzled, so he rubbed it hard and looked at it again. However, he finally confirmed that he was not dazzled, and he couldn't help shouting:

"I see."

At this moment, on a huge piece of paper, the densely packed strings of aligned digits are like a character painting. The digits 1 in all binary strings are regarded as the background, and the digits 0 form a string of numbers against this background: 03:13:

55.

"What does this mean? It seems to be a time. Is this a coincidence?" Xiao Yuan stared at the series of numbers and frowned.

"The probability of coincidence is infinitely close to zero."

Xiao Yuan quickly made some calculations in his mind and made a judgment, "This time must represent some special meaning."

At this time, Xiao Yuan was extremely impressed by the whimsical idea of ​​this encryption method. According to people's mindset, almost no one can think that information can be stored in this way, including him, Xiao Yuan. The reason why he can now

The discovery was entirely a coincidence.

At the same time, Xiao Yuan also thought that this encryption method can actually be further expanded. If what is displayed here is not time, but a matrix using some encoding method, and even the time dimension can be added to these matrices to form a encoding sequence, then

The amount of data contained in it can be further expanded, and its storage capacity can even increase exponentially. If the information obtained at this time is encrypted, its confidentiality will be greatly increased...

"It's amazing. This method deserves careful study."

Xiao Yuan suddenly felt a little excited, and his mind was flooded with thoughts for a while, but he was not thinking deeply about this issue at the moment. He had to find the meaning of this time as soon as possible, so he had to suppress his thoughts and found another group.

In order to save time this time, he no longer copied the data on paper, but used a software to arrange it in the order mentioned above. Sure enough, there was another time string, but the time value was different from the previous one. This time

is 02:':44, the time has been reduced.

After analyzing several sets of data one after another, Xiao Yuan got several time values. He compared these time values ​​with the data flow sampling time. He found that these times were several moments in a countdown, and he calculated

Countdown time to zero: :00, there is still more than an hour left.

"What is this countdown for?" Xiao Yuan was a little confused, but intuitively he felt that something big should happen when the time reaches zero. "What will happen after the countdown ends?"

Several possibilities flashed through Xiao Yuan's mind. None of these possibilities was a good thing because of the psychological impact that Tang Sa's absence for a day had on him. The most serious one was that he thought of a time bomb, or that the Xinhuayi Gang was targeting Tang Sa.

The major action taken by Sa...

Thinking of these bad things, Xiao Yuan looked at the time and saw that there was only a little more than an hour left. He couldn't sit still and wanted to spread the news urgently.

"What should I do? If I'm not afraid of ten thousand, I'm afraid of the worst. But what happened outside? Sister Sa will lock me in here and won't let me out. It's really annoying." Xiao Yuan stood up from his seat and walked in the room.

I walked back and forth several times and became extremely anxious.

"What should I do?" Xiao Yuan asked himself several times. He was as anxious as an ant on a hot pot in the room. Unknowingly, more than ten minutes of time were wasted, and the remaining time was reduced to zero with less than an hour left.

Ding dong, the computer issued a prompt, which brought him back from his anxious state. He sat back by the computer and found that Jessica was online and sent him greetings: "I attended an academic conference in the afternoon and was not in the experiment.

Shi, what do you want from me?"

"The matter has been settled, thank you, Jessica." Xiao Yuan replied, a little absent-minded because he had something on his mind.

"I can't help you. Sorry, are you in San Francisco now?" Because across the Internet, Jessica couldn't know that Xiao Yuan was not in the mood to talk to her at the moment. She probably discovered that his current IP address was in San Francisco.

So he asked.

"Yes, I have something to do in San Francisco. I originally asked you to tell Yingying for me, but you were not there, so I asked Han Xiaoyu to help me." Xiao Yuan replied.

"Has Han Xiaoyu sent a message to you? I saw Yingying this afternoon and she was still saying that she couldn't contact you and she didn't even eat lunch because she was worried about you." Jessica replied to Xiao Yuan asking him to

The unexpected news made him feel even more irritable instantly.

"Han Xiaoyu obviously promised me, didn't he go to Yingying? **, damn it." Then, Xiao Yuan's reply became irritable and even used swear words.

Jessica didn't reply to Xiao Yuan immediately, so that Xiao Yuan thought that she was frightened by her harsh words. This reminded him that he was indeed not calm just now, so he calmed down his emotions and wrote to Jesse.

Ka wrote another message: "Sorry, I ran into a lot of trouble and was in a bad mood. I shouldn't have said what I just said to you."

"It's okay, you misunderstood. I called Han Xiaoyu and asked. After you sent him a message, Tang Xinxin came to see him. He forgot what you asked him to do. This guy is really unreliable. I have already done it for you.

I have criticized him, and he is now looking for Yingying to help you pass the message." Jessica said.

"Thank you, Jessica." When Jessica said that Han Xiaoyu had so easily forgotten what she had repeatedly told him to do, she couldn't help but want to get angry again. She quickly took two deep breaths and tried to calm down.

He stopped and expressed his gratitude to Jessica.

"You're welcome. What kind of trouble have you encountered? Do you need my help?" Jessica asked.

Seeing Jessica's offer to help him, Xiao Yuan did not refuse. He pondered for a while and replied: "Jessica, I ask you to go find Yingying yourself and ask her to go home immediately. Go home."

Then I opened the Compaq laptop and connected it to the Internet. I have something important to ask her."

"Okay, I'll go now." Jessica said.

"Remember, be quick, I don't have much time left." Xiao Yuan looked at his watch and saw that almost ten minutes had passed before he knew it, so he said.

"Okay, I'll drive Yingying home." Jessica said.

"Thank you, go quickly, I'll wait here." Xiao Yuan said.

Jessica did not reply to Xiao Yuan. Soon Xiao Yuan saw that her status had changed to offline. She must have left the laboratory to find Xia Jiuying, so he turned on a network scanner and began to detect it continuously.

As for the IP address of your computer at home, as soon as it comes online, you can find it here in time.

About ten minutes later, Berkeley's home computer came online, so he logged into the computer through the backdoor he had set up in advance, established a conversation process on it, and sent a message: "Yingying, it's you.

?”

About ten seconds after the message was sent, a message came back: "It's me. I'm with Jessica. I heard Jessica said you were in trouble in San Francisco. What happened?"

Xiao Yuan was stunned, and then wrote: "Yingying, let Jessica talk to me. You go find the master. The matter is urgent. I will explain to you when the matter is resolved."

"Okay." Xia Jiuying replied, and then another message came back: "I am Jessica, what do you need me to do?"

Xiao Yuan hesitated for a moment, and then wrote a message: "Jessica, can I trust you?"

ps: I have been busy with trivial matters these past two days, and the updates are a bit abnormal. Sorry, it should be better tomorrow.
