Chapter 30
At the same time, Zhou Yichen, who was already in the car, looked at the unfamiliar account on the computer and raised his eyebrows.
If he hadn't taken out his computer to prepare for work, he wouldn't have discovered this powerful attack.
Based on the ability of the opponent to operate, the rank is not low.
The location the other party browses is the barrage review team of the variety show, who could it be?
Zhou Yichen was still thinking about it, when a window popped up on the calm computer.Zhou Yichen clicked in almost without thinking.
At the front of the blue screen, there is a string of characters: \——\-\-\.\\-\-\-\——\\.\——
Zhou Yichen understood the meaning after just one glance: Please don't interfere with the barrage order, understand?
Zhou Yichen's face didn't fluctuate at all, and he tapped on the keyboard with both hands at a speed that dazzled people.Lin Zhi was driving the car in front, looking at the man in the back seat through the rearview mirror.
I don't understand what's wrong with the boss. He said he kept tidying up for a while after he was discharged from the hospital, and there was no possibility of turning things around.He was worried about the big brother's injury, but he didn't seem to be aware of it.
What's even more strange is that he seems to find that the boss seems to be in a bad mood. Is it because of the cheetah before?
His eyes fell on Zhou Yichen's stained neckline again, and he became more and more puzzled.
The boss's cleanliness, how can he allow his clothes to be dirty?The sun came out from the west.
Internet cafe.
Almost within 30 seconds of Ning Qing's provocation, a group of English characters appeared on the computer, and a new message appeared below it.Ning Qing stared at the things above and sneered, and the words Hill Code appeared in her mind.
It's just a matter of adding matrix operations.
Hill cipher is a type of multi-letter substitution cipher.Multi-letter substitution ciphers can be conveniently described by matrix transformation, and are sometimes called matrix transformation ciphers.Let the plaintext alphabet be Z, and if L letters are used as the unit for substitution, then the multi-code substitution is a mapping f:Z→Z.If the mapping is linear, then f is a linear transformation, which can be represented by an L×L matrix K on Z.If it is of full rank, the transformation is a one-to-one mapping, and there is an inverse transformation K.The number of L letters is expressed as an L-dimensional vector m on Z, the corresponding ciphertext vector c, and mK=c, and K is used as the decryption matrix, and the corresponding plaintext c·K=m can be recovered from c.
There are three keys to deciphering the Hill cipher: 1. Guessing that the text is converted into a few-dimensional vector (the number of rows of the column matrix); 2. How the corresponding alphabet is arranged; 3. Trying to obtain the encrypted matrix A.
If you want to crack the password, you must know the dimension of the vector, the permutation table of the letters, and the encryption matrix.
Ning Qing tensed her nerves, stopped her hands, and her brain began to run rapidly, calculating the results.All kinds of matrices flashed in my mind, inverse matrices, matrix multiplication, and the process of decryption went back and forth, and I didn't dare to be careless at all.
Ning Qing tapped her fingers on the table.
After spending 2 minutes, she decrypted a string of numbers: 221415147.
The superficial meaning of this number may not be able to find anything, Ning Qing quickly reacted, and decided to use the method of converting numbers to letters to draw a conclusion. The deduction is: BUDONG.
Ning Qing: "..."
It's changed, but you just don't understand?
Ning Qing stared at the computer for a while, and then started to move again.
At this moment, Zhou Yichen, who was about to get home, tugged at the collar of his buttoned shirt, looked at the more difficult password coming out of the computer interface, tugged at his lips, and started typing on the keyboard.
Lin Zhi looked at Zhou Yichen, who was still working behind him, and said in a low voice, "President Zhou, you are still receiving fluids."
Zhou Yichen's movements did not stagnate in the slightest, but became faster and faster, as if he didn't take his words to heart.Lin Zhi adjusted his glasses, stopped the car, and the people behind slowly said, "Shut up, make noise!"
Lin Zhi: "..."
Ning Qing didn't stay in the Internet cafe any longer, wiped out all traces, and turned off the computer.When passing by the front desk, I happened to see the boss playing a game, and the computer screen in front of me suddenly went black at this moment, and I was so angry that I beat the table: "Fuck! Fuck! I'm going to ride the horse—"
Realizing that someone was looking at him, the boss turned his head, met Ning Qing's gaze, and immediately faltered: "It's okay, it's just a game. Hahaha, I'm laughing."
Ning Qing didn't care, and walked out of the Internet cafe quickly.
The afternoon sprint selection started soon, and when Ning Qing arrived at the track and field, Xu Mengmeng had already returned.
Jiang Yi, who hit up a conversation in the morning, was talking with Zhao Qingyue, talking and laughing.
Lu Ying and Xu Mengmeng were still together, but there were some new faces around Lu Ying.
As soon as Ning Qing sat down, the camera came to the right, and Zhao Qingyue whispered in her ear: "I have good news for you, the picture of that thing has been cut that night, and it is not in the replay."
Ning Qing nodded indifferently: "Yes."
"Also——" Zhao Qingyue suppressed her voice, "I watched the bullet screen, it was absolutely terrible, and my blood boiled with excitement. I have a feeling that you are a dark horse in this show."
"Dark horse?" Ning Qing pulled his lips, "I think it's more like a toad."
Zhao Qingyue was blocked by her words, speechless, and then patted her on the shoulder and said earnestly: "Xiao Ningzi, we human beings, we should not underestimate ourselves. Maybe one day, we may become the birds flying in the nine heavens .”
Ning Qing teased, "Isn't it good to be a human? Do you have to be a bird?"
Zhao Qingyue was choked again, and laughed for a while, "Ning Qing, you hammer! A hammer without emotion!"
Jiang Yi sat beside them and listened to their chatting and laughing, and also rolled his eyes.
The hostility and laughter on the barrage coexist:
[I'm going, is this little internet celebrity who is rubbish still getting popular? 】
[What did Yueyue and Ningning say?I really want to hear what to do? 】
[Ivy and Ningning will always be together! 】
[God, what happened here?Is there anything I can't hear on my V12? 】
[Ning Qing Sima!Ning Qing is not dead, I will not give up! 】
[Sister Maggot has someone rubbing against her?Who gave the face?It's close to Yueyue, but it's okay if you don't like it. 】
[What's so great about it?Sister Maggot is also a good figure, vomit! 】
[Vulgar people attract vulgar people, I really can't compliment you. 】
[Garbage attracts garbage, noble I have never understood. 】
[What's so great about being the first in swimming?It's 20 seconds when I can breathe, hehe! 】
[Can a rubbish grade be blown up to the sky?Just go to the trending ones, I'll go, anyone around me will hang and beat her! 】
[An elementary school student who has never seen the world has a crush on a maggot sister who has bad views, and we are all speechless! 】
[It can only be said that garbage and maggots are a natural pair, a perfect match! ! 】
[Has no one noticed that those blocking words are back? 】
[Just come back, Aunt Ning, get out of the show as soon as possible!I don't watch it! 】
[Ivy, work! 】
At this time, there was a burst of commotion in front, and amidst the cheers of the people, Yang Tianjin stood on the stage in front of the crowd, dressed in sports attire, very energetic.
That kind of fit and handsome temperament is not inferior to any little fresh meat. It has a higher reputation in the barrage and a better reputation.
"Good afternoon, everyone!" Yang Tianjin took the microphone, turned his eyes around, and landed on Ning Qing at the end.
The woman in sight has a ball head and is tall and tall. Even if she stands at the end, she is still the most eye-catching one. cute.
"I'm very glad to be invited to this program as your sprint coach. In fact, I'm not a talented person, and I don't know much. All success requires continuous efforts and attempts. I can communicate with others. Yours is the most basic knowledge. On my side, those who can communicate with you include 50 meters, 100 meters, and 150 meters—"
[Representative of Versailles! 】
[Athletic trapeze: I can't run. 】
[E-sports master: My hand speed is average. 】
[In front, there is reason to suspect that you are playing with colors. 】
After some explanations, the selection officially began.
The first is the popularity of 50 meters.Warm up first, and then adopt squatting and semi-squatting. You can start running after the whistle blows. Otherwise, it will be regarded as a violation. If you violate the regulations twice, you will immediately withdraw from the race.When running, it should be noted that it is the knee that is raised, not the heel.
Because Ning Qing's performance in front was too outstanding, the program group arranged for the girls to run first.attract the audience.
Because the popularity of some live broadcast rooms was too bleak, they were simply reduced to five.
Ning Qing has now become the one with the highest voices, amidst the eager anticipation or disdain of the people and bullet screens at the scene, in the sixth round, Ning Qing stood at the starting line.
