om, hello, Master Huo's latest chapter!
"You can crack it in one day and one night?!" Zhao Liangze and Yin Shixiong yelled at the same time, "Since the United States announced that it has cracked the channel code of the Copernicus system, Europe has changed the original code. You have to crack it again. One day Is one night really enough?!"
Deciphering this code requires a computer with powerful computing power.
In order to crack the channel code of the Nandou system, the School of Electrical Engineering of Harvard University used a supercomputer, running around the clock, to be able to crack it.
If you use Gu Nianzhi's small laptop, you probably won't be able to figure it out until the end of time...
Huo Shaoheng also raised his head from the other end of the computer, staring at her with deep and dark pupils. Although separated by the computer screen, they seemed to have the penetrating power to see through people's hearts.
Gu Nianzhi was so overwhelmed by his gaze that he had to lower his eyes, not daring to look at Huo Shaoheng again, and whispered: "...I remember that there are original records of signals about the Copernicus system on the website of Classmate Xin. Although the data looks a lot, it is actually more cluttered and interfered. If the cluttered signals can be eliminated, the amount of data will be greatly reduced, and the required computing power will also be reduced accordingly. My computer..." She looked up at Zhao Liangze in the corner of the video on the computer. He said with a smile, "...it was modified by Ozawa. Although it is not as good as a real supercomputer, it is much more powerful than ordinary computers."
Huo Shaoheng turned his eyes suddenly, and looked at Zhao Liangze who was sitting next to him, "...you modified Nianzhi's computer? Why didn't I know?"
Zhao Liangze wished that Gu Nianzhi would shut up.
Did you agree not to let Huo Shaoheng know? !
This little unscrupulous fellow!
If I had known that Xiao Nianzhi had no backbone in front of Huo Shao, not only did he not ask himself for many things, but he also did not ask himself!
This little girl is really afraid of Huo Shao to the core...
While slandering Gu Nianzhi and Huo Shaoheng, Zhao Liangze put on a dull face and shook his head like a fool: "...the goose doesn't know~~(╯﹏╰)b..."
"Bah!" Yin Shixiong met on the opposite side, secretly scolded Zhao Liangze for pretending to be stupid, how could Huo Shao let him go?
Sure enough, Huo Shaoheng gave him a cold look, stood up and said, "Then you accompany Nianzhi to crack the code. Don't sleep." He walked out.
Zhao Liangze hurriedly answered "Yes!", and then made a face at Gu Nianzhi, "Xiao Nianzhi, you betrayed brother Xiaoze...hehehehe..."
Seeing that Huo Shaoheng was gone, Gu Nianzhi immediately became lively, and made a face at Zhao Liangze, "I'm going to betray you, what's the matter?! In front of Uncle Huo, I know everything without saying anything. Brother Xiaoze, you should have understood .”
Gu Nianzhi looked cute and playful, and Zhao Liangze was also drunk.
"Forget it, forget it, I'm an adult and don't care about villains, come, tell me what you plan to do?" Zhao Liangze shook his head with a smile, and got back to business, he must solve this problem quickly.
Gu Nianzhi's eyes lit up immediately, and she briefly stated the method she was thinking of, and showed it to Zhao Liangze with a diagram: "Brother Xiaoze, I have carefully studied their cracking process, and I think the biggest problem is not the calculation. , but how to exclude signal impurities.”
The signals recovered from the satellites of the outer satellites thousands of miles high will receive various interferences.
The process of cracking the channel code is actually a process of eliminating interference, capturing useful signals, and restoring the code according to the established order.
In order to achieve this goal, there are many methods available.
What Xin Xinggao and his team did was actually relying on a supercomputer and an "insider" to lead the way, and used exhaustive methods of forced supercomputing to find out the channel password rules.
Gu Nianzhi does not have a supercomputer, and even if he did, their time would not allow it.
Therefore, in order to quickly and quickly decipher the code, Gu Nianzhi first thought of sorting out the signal. The first step is to eliminate those interfering impurities, so that the amount of remaining data will be greatly reduced, and the calculation process can be greatly shortened.
There are three processes when a satellite transmits a signal, which are source coding, encryption coding and channel coding for the signal.
When cracking, it is the opposite, starting from channel coding.
What Xin Xinggao and the others did, from beginning to end, was only the outermost step, which was to decipher the channel code.
Gu Nianzhi's small program is to eliminate background noise in advance and filter out useful signal codes.
Zhao Liangze's eyes widened all of a sudden, and he couldn't help but exclaim: "What a great idea! What a great idea to find another way! ——How do you plan to deal with Copernicus' signal interference?"
Gu Nianzhi recalled a small program software he wrote yesterday, "Brother Xiaoze, take a look at my thing, can it achieve the purpose I just said?"
Zhao Liangze took control of Gu Nianzhi's computer, directly opened the small program software and went through it. While looking at it, he optimized and improved some places for her, but did not make any changes to the entire software structure.
He couldn't help but praised: "Near it, don't study law, come and learn computer from brother Xiaoze. I promise you will become the greatest hacker in the world! You will be better than blue and become the best hacker who steps on your little one! Brother Ze, a great man on the shoulders of giants!"
"Bah!" Gu Nianzhi pouted, "You really know how to put gold on your own face. ——Okay, stop rambling, let's start."
"Okay, have your data been saved yet? Input it into the computer, go." Zhao Liangze turned on his computer and started sending signals to the Copernicus system to intercept the latest signal information.
The two worked all day and night in front of the computer.
I only gnaw bread when I eat, and drink some water when I am thirsty.
Apart from going to the bathroom, the two never left the computer desk.
Of course I never slept with my eyes closed.
Because of Zhao Liangze's help, Gu Nianzhi didn't even spend 24 hours, but only took 20 hours to crack the latest channel code of the Copernicus system, as well as the second layer of encryption code.
Not only was it many times faster than the American team, but it also went farther than them.
After cracking the encryption code, Zhao Liangze and the others can use the Copernican system without any scruples, without worrying about being discovered by those who maintain the Copernican system.
When Huo Shaoheng came back from his morning practice, he heard that the password had been cracked, so he patted Zhao Liangze on the shoulder, "Go to bed, and act at night."
Zhao Liangze immediately stood up, his legs fluttered, and he went to his own bed, fell asleep and fell unconscious.
For the past twenty hours, he and Gu Nianzhi worked under high-intensity conditions, and it was not easy to sustain it.
Huo Shaoheng looked at Gu Nianzhiqiang's wide open eyes on the video, and his voice softened a lot: "...Nianzhi, you go to sleep too." After a pause, he asked in a low voice, "Are you tired?"
"I'm not tired, I'm not tired at all." As soon as Gu Nianzhi was concerned by Huo Shaoheng, he was so excited that he couldn't find the north. "I still have something to do! Uncle Huo, wait, I will avenge you!"
The corners of Huo Shaoheng's lips curved slightly, and he shook his head and refused: "Be obedient."
He looked at Gu Nianzhi silently, and there was a trace of tenderness in his heart-palpitating eyes that he didn't even notice.
Gu Nianzhi was so intoxicated by him, it was almost hypnotic, and soon drooped his eyelids, and fell asleep on the computer desk.
Yin Shixiong snorted, and carried Gu Nianzhi to her bedroom in his arms.
Seeing it from the video, Huo Shaoheng pursed his lips imperceptibly, tapped his fingers, and turned off the video with a snap. --Out of sight out of mind……
