A few days after the kitten took Hanlon's laptop and internet communication equipment, the two of them met in a secluded park.

The kitten looked at Han Long excitedly and said, "Brother Long! I have given our computers and network equipment according to the city's LAN dedicated communication security card, and at the same time applied for a random floating IP account for the computer, which can be attached to and use any legitimate ready-made IP account to access the Internet! Random floating IP accounts can evade any inspection by the network supervisor! Therefore, starting today, we will crack the flight center LAN, and at the same time crack the communication protocol between the city's LAN and the satellite network, as well as crack the communication protocol between the satellite network and the Internet, etc.! That way, we'll be able to move on to the next step! ”

Han Long said excitedly: "How long does it take for these jobs? ”

"If it goes well, it can be done in a month and a half! If it doesn't go well, don't say it! ”

"Oh! Then let's hurry up and get to work! Where is the duty station going to be located? ”

"Brother Long! Let's stay in your dorm! You're a life physicist, and most people think you don't understand network technology! Even if something happens, people won't suspect you! ”

Han Long wiped the sweat from his forehead and said, "Okay! Bring your equipment to my room tonight! ”

After that, Han Long and Kitten used their evenings and rest days to decipher the communication protocols and secret documents of each gateway in Hanlong's dormitory.

When they work, they constantly change the nearby legal IP addresses that can be retrieved by computers and network communication equipment to surf the Internet, so it is difficult for network supervisors to monitor their behavior on the Internet.

Half a month later, Kitten and Hanlong cracked the LAN of the Science City Flight Control Center, and they could freely access any database of the LAN, as well as the office command control and transmission system.

At this time, Kitten began to pre-make his and Hanlong's pilot electronic files in accordance with the file format and management methods of the LAN, and the electronic files used the kitten's or Hanlong's electronic photos, electronic fingerprints, electronic blood types and other personal identification data.

At the same time, 4 hours before the operation, they had to replace the files of the two real flight control center registered pilots with these two ready-made electronic files!

After that, they began to decipher the communication protocols and secret documents between the city's LAN and satellite networks, and between the satellite network and the Internet.

Due to the new hardware and software encryption technology used in the communication protocols and secret documents of these gateways, after a month, the kitten was still unable to crack them despite all his efforts.

One night, Hanlong and Kitten sat on the grass in the park near their dorm building and talked.

Han Long looked at the kitten in confusion and said, "Kitten! Why are these gateways so hard to crack? ”

The kitten smiled bitterly and said: "The communication protocols and secret documents of these gateways are in a floating state, so we can't crack them with a fixed algorithm program!" Unless we get the running algorithm program that controls this floating state! Otherwise, it would be impossible to hack these gateways on our laptops! Even if you hack these gateways on a supermax computer, it won't be possible to hack them in a few years! ”

Han Long said in despair: "Alas! So we can only wait to die in this science city! ”

The kitten smiled and said, "Brother Long! Maybe not so pessimistic! The technical director of our network maintenance and repair office is a Chinese, he is in his 40s, he used to work in the Internet maintenance and repair center of Science City, because he offended the white director of the institute, so he was assigned to work in our office! This person must have that program that controls the floating state of the gateway! If we find this person to work with, all our problems will be solved! ”

Han Long said excitedly: "Okay! Kitten! You use the job opportunity to get in touch with this person and get to know their personality and ideas in advance! Let's talk to him if it's appropriate! ”

The kitten nodded and said, "Okay! When I go to work tomorrow, I'll go to his office and ask him a few questions! ”

......

One evening a few days later, in a small park near the 116 building, Hanlong and the kitten sat on the grass and talked.

The kitten looked at Han Long and said, "Brother Long! That person I touched! I feel that this person is unfathomable, and I can't grasp his character and ideas! Why don't I ask him out, and you can talk to him!" ”

Han Long smiled and said, "Okay! Tomorrow when you go to work during the day, you find a reason for a network failure, ask that person to come to my office, and I'll talk to him! ”

"Okay! Tomorrow I will take him to the Biology Institute Supervision Office to find you! The kitten looked at Han Long innocently.

Shortly after going to work the next morning, Kitten brought a middle-aged Chinese man to Han Long's office at the Institute of Biology.

Although the middle-aged Chinese man is in his 40s, he looks only in his 30s, he is of medium height, very thin, very energetic, fair skin, black hair, typical Chinese appearance.

The three of them made a coffee conversation on the couch.

The middle-aged Chinese stared at Han Long expressionlessly and said, "I heard that your name is Ah Long!" I am also Chinese, my name is Liu Shan, and most Chinese people call me Brother Shan! You name it! ”

Han Long smiled and said, "Brother Shan! It's such an honor to meet you! I have a few questions for you! ”

Liu Shan smiled and said, "Okay! You say! ”

"Brother Shan! The supervisor of my biological research institute and the staff in the research department of the institute reported to me that they often lose some network data, which makes it difficult for them to carry out their research work! How should these problems be solved! ”

"Alas! Nowadays, there are more and more biological scientists who have mastered network technology, so when they encounter competition, they will attack each other through the network, throw computer viruses to the competitor to plagiarize, and delete the opponent's data is a common thing! As long as the competition is still there, this kind of thing can't be avoided! Let them take precautions themselves! The precautionary measures are, first, to minimize working in a network environment as much as possible; Second, when working in a network environment, the data that needs to be saved should be saved to the mobile memory isolated from the network in a timely manner. Maybe that's the way to do it! ”

"Thank you, Brother Shan! Brother Shan! Where do you say these cyber hackers come from? Our director, Dr. Clad, said that these hackers could come from the Internet in the outside world. ”

Liu Shan said a little nervously: "Impossible! The city's LAN and the Internet in the outside world, that is, the Internet, have two gateways and secret files, and it is impossible for personal computer-based hacking technology to break through these two gateways! Unless someone gets their hands on the dynamic runners of these gateways! ”

Han Long stared at Liu Shan with a serious face and said, "Brother Shan! Who is most likely to get these programs, you say? ”

Liu Shan wiped the sweat from his forehead, he looked at Han Long with a begging gaze and said, "It's hard to say, but it must be those who have been exposed to the program!" Aaron! If you have a conclusive discovery, you can tell me directly! ”

Han Long nodded in understanding and said, "Okay!" Tonight you go to the little park near the 116 building, where we talk! ”

After Liu Shan breathed a sigh of relief, he smiled and said, "Thank you!" I live in the 117 building and I'll be waiting for you there after dinner! ”

After the conversation, Liu Shan and the kitten left.

In the evening, in a small park near the 116 Building, Han Long, Kitten and Liu Shan sat on the grass and talked.

Liu Shan stared at Han Long and said, "Ah Long! What did Clad tell you? ”

Han Long smiled and said, "Brother Shan! He said you know how the intranet and the extranet are connected! ”

Liu Shan said angrily: "This dead ghost! As you know, Crader often sells your research to private companies in the outside world through the Internet, and makes a profit. Last time he asked me for that procedure, but until now he hasn't given me the money! Now maybe he lost that part of the program, so he asked you to ask me! You tell Clad that he won't pay me double this time! He didn't want to get that program from me! ”

For the first time, Han Long knew about the transaction between Clad and Liu Shan, Han Long held back his excitement, and he pretended to be calm and said, "Brother Shan! I don't care about the matter between you and Clad! This time I want it myself, so let's talk about the price! I can pay you cash! ”

Liu Shan was shocked and said, "Oh my God! What do you want this for? ”

Han Long smiled and said, "The kitten and I want to leave here and return to the free world!" ”

Liu Shan excitedly wiped the sweat from his forehead and said, "I feel that you have the ability, you can do it!" But you must take me with you! If you don't take me, I won't give you that thing, and I'll go to HQ to denounce you! ”

Han Long smiled and said, "Okay! We bring you! When I get back to the free world, I'll pay you a huge sum of money! How much money do you think I'll give you? ”

Liu Shan smiled excitedly and said, "Deal!" I've been in this place for over 20 years and I'm really fed up! Returning to the free world is my lifelong dream! When I get back there, you solve my food and housing problems, and then you can give me a little more pocket money! I'm not demanding! ”

The three of them looked at each other, and they smiled happily!
