Chapter 33: The Battle (Seven Watches)
"The captain of the second team is a dominatrix, this is the information I want to encrypt."
I slapped the mushroom head on the back and said, "Brother, go!" ”
Mushroom Head stood up, took a folder, walked to the podium, and then bowed to the old instructor and the principal in a regular manner, and then projected the things in his hand on the screen one by one, cleared his throat, and then began to speak.
I said in my heart that this mushroom head still has the talent to be a teacher.,I talked about the whole encryption program from beginning to end.,Although he didn't use any advanced mathematical algorithms.,It's just a relatively simple logical attack process.,Easily and briefly described the process of file encryption.。
"I think the ordinary encryption method, even if the algorithm is advanced, the more layers of encryption, there is a possibility of being breached, so we thought that we can represent the data in a graphical way, so that some data can be hidden, if you know the method and procedure of decryption, but the information in the whole chart is not all mined out, and it is not possible to solve all .....the messages."
The mushroom head talked eloquently on it, not at all like he hadn't slept for two days, and the old instructor sitting below nodded frequently, and sometimes smiled heartily in agreement.
With his explanation, Tang Lei's face became more and more ugly, and it was already red and purple, and finally the mushroom head concluded: "In the end, this information - the captain of the second team is a dominatrix, and it becomes this picture." ”
The old instructor took the lead in applauding, the members of our first team applauded loudly, and the second team seemed to be dumb, bowing their heads and not making a sound. In the end, Tang Lei slapped the table and said, "Even if we didn't crack your things, then did you unlock our things?" ”
The mushroom head was full of confidence, took out a few more pages from the folder, put them on the projector, and said slowly: "Originally, you guys who wrote this encryption do have two brushes, to be honest, if you just look at this line of letters, there is really no way to start, but don't forget what school we are studying,"
As he spoke, he threw a look at me, very proud. I gave him a thumbs up and said mushroom head! Yes, the hard work of my brothers and sisters these days depends on you.
Mushroom Head said: "If it weren't for the participation of all members of our team, we used some special means to find out which one this programming brother is, and I have figured out some characteristics and information of this brother." I really don't know where to start, his programming methods, speaking of conscience, are more clever than mine, there are difficult mathematical theories in it, plus 4 layers of encryption, it really made me suffer a little, but, it was still deciphered by us. ”
As he spoke, he projected the deciphered results onto the screen.
"Zhang Chengnan of the first team, you will definitely lose to me, and the second team will win!"
All the members of the second team were dumbfounded, especially Tang Lei, whose jaw almost fell to the ground, at this time, the man with glasses suddenly stood up, very excited, and said, "You.... You, this is impossible, I used the 9-digit algorithm to add encryption, impossible! ”
Shen Ling secretly laughed, and said softly behind me: "Sure enough, it's this guy, from the analysis of what we got, this guy is the one who works in the second team, a master of mathematics, hehe, boss, your method has played a big role, at least there are some detours." ”
Tang Lei suddenly made an expression of sudden realization: "I understand, did Zhang Chengnan use some shady means, directly in my place, aimed at the original text, isn't it?" ”
"Oh, don't worry, if I use any shady means, have you found out? But you threw some bits and pieces at my house,"
As I spoke, I put the bugging device I took out of our bedroom in my hand, Tang Lei's face changed greatly, and he was stunned, not knowing what to say.
At this time, the principal was interested, looked at our two captains with bright eyes, and said: "This paragraph, you two will report to me later, and now let this student tell us all the process of deciphering." ”
The mushroom head cleared his throat and continued to explain,
In fact, in all fairness, this encryption is indeed beautiful, no wonder the glasses man of the second team is so confident, he is really a master, but we have all the complete set of intelligence information to back it up, investigate it one by one, narrow the scope, and finally break it. It seems that this kid is still on par with the mushroom head.
After the mushroom head finished speaking, we all understood, vivid and appropriate, I used to think that the class was such a painful thing, especially like a boring course like cryptography, but now I unconsciously understand it completely.
The old instructor was a little surprised, stood up and looked at the front of our two teams, and said slowly: "This year, you have opened my eyes, there used to be a saying, that Old Man Li's class in the secret service school was the most boring, and now it seems that Old Man Li's class is also very interesting." Hahaha, you can do it! It exceeded my expectations, how will I teach you in the future? ”
The principal asked the old instructor to sit down, and then walked up to the podium, and said in a loud voice: "You have opened my eyes, how did I hear about something bits and pieces when I was listening to the class just now, I can't see anyone or something, you two captains, give me a detailed introduction." ”
Tang Lei seemed to be indignant, determined that I used some ulterior means, and directly stole the original text, he stood on the podium, and said: "Although I am very angry with Zhang Cheng's approach, but I also have such a practice, first put a few bugs on the station of the first team, I want to know their clues, and then I heard that they asked a person named Li Hansheng to write encryption, and the rest of the people are doing what they are doing, I found a way to go to Instructor Sally's office to find Li Hansheng's information, and found that he is a student of architecture." Judging by these information, decryption began.
Sally sneered and laughed, "There is no one named Li Hansheng on our team at all.....
The principal motioned for me to say, I stood up, slowly and logically, I explained how to arrange, how to arrange people to place bugs, how to collect intelligence, how to drop the personnel details of the first team, how to steal the personnel details of the second team, all one by one, everyone was like listening to a commentary, listening with relish, and the principal also listened while nodding.
turned around to talk about Tang Lei, and while listening, his expression was uncomfortable. In the end, the whole person buried his head on the table. He lost, not at his own level of encryption, but on the overall intelligence.
