Chapter 123

"You can crack it in a day and a night?" Zhao Liangze and Yin Shixiong cried at the same time, "since the United States announced that it had cracked the channel code of Copernicus system, Europe has changed the original password. If you want to crack it again, one day and one night is enough! "

To crack this code, you need a computer with powerful computing power.

In order to crack the channel code of Nandou system, the school of electronic engineering of Harvard University uses supercomputer to run day and night, which makes it possible to crack the channel code.

If you use the small notebook computer that you care about, you can't calculate it until the end of time

Huo Shaoheng also raised his head at the other end of the computer. His dark eyes fixed on her. Though separated from the computer screen, it seemed to have the penetrating power to see through people's hearts.

Thinking of it, he could not breathe, so he lowered his eyes and did not dare to look at Huo Shaoheng again. He whispered, "I'm afraid you can't look at Huo Shaoheng again I remember the original records of Copernican signals on their website. Although the data seems to be more, it is actually more cluttered and interfered. If the clutter can be eliminated, the amount of data will be greatly reduced, and the computing power required will also be reduced accordingly. My computer... " She looked up at Zhao Liangze in the corner of the video on the computer and said with a calm smile: " It's modified by Ozawa. Although it's not as good as a real supercomputer, it's much more powerful than ordinary computers. "

Huo Shaoheng suddenly turned his eyes and looked at Zhao Liangze sitting beside him You've modified your mind's computer? Why don't I know? "

Zhao Liangze wanted to shut his mind.

Agreed not to let Huo Shaoheng know?!

This little unruly guy!

I knew that xiaonianzhi had no backbone in front of Huo Shao. Many things not only did not recruit themselves, but also did not ask for self Recruitment!

This little girl is really afraid of Huo Shao. She's afraid to the bone

Zhao Liangze thinks about Huo Shaoheng and his stomach Fei. He puts on a dull face and shakes his head in a demented way: "I'm sorry The goose doesn't know

"Pooh!" Yin Shixiong in the opposite, secretly scold Zhao Liangze will pretend to be stupid, how can Huo Shao let him go?

Sure enough, Huo Shaoheng looked at him coldly, stood up and said, "you can read the password with me. No sleeping. " He walked out.

Zhao Liangze quickly shouts "yes!" Then he made a grimace at the thought, "xiaonianzhi, you betrayed brother Ozawa Ha ha ha... "

Thinking of Huo Shaoheng left, immediately lively, also made a face to Zhao Liangze, "I betrayed, how to do it?! In front of Uncle Huo, I know everything and say everything. Brother Ozawa, you should have understood

Thinking of one of the Deputy Meng Meng Da's villains, Zhao Liangze is also drunk.

"Forget it. I'm an adult. I don't care about villains. Come on, what are you going to do?" Zhao Liangze smiles and shakes his head. To get back to the point, he should quickly solve this problem.

Her eyes suddenly brightened. She simply said the measures she wanted and showed it to Zhao Liangze with a chart: "brother Ozawa, I have carefully studied their cracking process. I think the biggest problem is not in calculation, but in how to eliminate signal impurities."

All kinds of interference will be received from the signals recovered from the satellites of the outer satellite at high altitude.

The process of cracking channel password is actually a process of eliminating interference, seizing useful signals, and restoring coding in accordance with the established order.

There are many ways to achieve this.

In fact, with the help of a supercomputer and a "insider", Xin Xingyao's group tried to find out the channel cipher rules by means of forced super computation.

If there is no supercomputer, their time is not allowed.

Therefore, in order to decode the code quickly and quickly, the first thing to think about is to sort out the signal. The first step is to eliminate the interference impurities. In this way, the amount of remaining data will be greatly reduced, and the calculation process can be greatly shortened.

There are three processes in satellite signal transmission, which are source coding, encryption coding and channel coding.

And when cracking, it is to do the opposite, starting with channel coding.

What they did, from the beginning to the end, was the most peripheral step, which was to crack the channel coding.

Consider this small program, is to eliminate the background noise in advance, filter out the useful signal code.

Zhao Liangze's eyes suddenly glared up and couldn't help but exclaim: "good idea! What a good idea to find a new way! ——How do you plan to deal with Copernicus' signals? "

Thinking of the transfer out of their own yesterday wrote a small program software, "Ozawa, you see this thing, can I achieve the purpose I just said?"

Zhao Liangze took control of the computer he was thinking about. He directly opened the small program software and went through it. While watching, he optimized and improved some places for her. However, he did not make any changes to the whole software architecture.

He couldn't help but praise: "read, don't study law, come and learn computer from Ozawa. I promise you will be the greatest hacker in the world! You will be better than the blue, and become a great man stepping on the shoulders of your giant, zego"Pooh!" Thinking of the mouth, "you can really put gold on your own face. ——Well, don't talk nonsense. Let's get started

"OK, have you saved your data? Enter the computer, go. " Zhao Liangze opened his computer and began to send signals to the Copernicus system to intercept the latest signal information.

They worked in front of the computer for a whole day and a night.

When eating, only eat bread, thirsty drink some water.

Apart from going to the bathroom, they never left the computer desk.

Of course, I didn't close my eyes and sleep.

Thanks to Zhao Liangze's help, he didn't even use 24 hours to crack the latest channel password of Copernicus system and the encryption code of layer 2.

Not only was it many times faster than the American team, but it went further than them.

After cracking the encryption code, Zhao Liangze and his colleagues can use the Copernicus system without fear of being discovered by the people who maintain the Copernicus system.

Huo Shaoheng came back from morning exercise and heard that the password had been cracked. He patted Zhao Liangze on the shoulder, "go to sleep and act at night."

Zhao Liangze immediately stood up, beat his legs, went to his bed, fell unconscious.

In these 20 hours, he and his mind are working under high-intensity conditions. It is not easy to support them.

Huo Shaoheng looked at the big open eyes in the video, and his voice softened a lot Read it, you go to sleep After a pause, he asked in a low voice, "tired or not?"

"No, no, I'm not tired at all." Thinking about it, Huo Shaoheng was so excited that he couldn't find the north. "I still have something to do! Wait, uncle Huo. I'll avenge you! "

Huo Shaoheng's lip angle hooks up a shallow arc, shakes his head and refuses: "be obedient."

He looked at and thought of it in silence. There was a trace of tenderness in his cold and palpitating eyes.

He was drunk to think about it, just like hypnosis, and soon drooped his eyelids and fell asleep on the computer desk.

Yin Shixiong Chua, conveniently will care of the embrace to her bedroom.

Huo Shaoheng saw from the video, almost imperceptibly pursed his lips, fingered lightly and snapped off the video. ——Out of sight, out of mind
