Not long after hanging up the phone, an iron door at the end of the corridor opened, Xiao Qing came out gracefully from inside, wearing a professional suit, her mature charm made Yang Ming a little impulsive.
"I'm sorry, I forgot that there is a fingerprint lock!" Xiao Qing apologetically straightened her loose hair, smiled at Yang Ming, and opened the fingerprint lock.
"It's okay." Yang Ming entered the iron gate, and then said, "Sister Xiao Qing, you look so good today."
"Don't talk nonsense, there is surveillance here." Xiao Qing glared at Yang Ming and said, "Don't touch me."
"Oh!" Yang Ming naturally saw the camera in the corner, otherwise Xiao Qing would have hugged Xiao Qing as soon as he came up, after all, he hadn't seen Xiao Qing for a long time.
"What are you looking for?" Xiao Qing took Yang Ming into her laboratory just now. There was a doctoral student in the laboratory researching something on the computer. Yang Ming glanced at it but didn't understand it, as if he was designing something. model.
Entering the back room of the laboratory, this is Xiao Qing's territory. There are no outsiders here. Naturally, Xiao Qing will not be polite to Yang Ming, and just sits on the boss chair by herself, tilting her head back, and comfortably Put your hands on your lap: "These two days, I'm going to be exhausted."
Yang Ming sat on the sofa beside him, because there was a camera here, although he didn't know if it was activated, but Yang Ming didn't dare to make a mistake casually.
Come to think of it, this kind of high-end laboratory will install cameras to ensure safety.
"The camera is not activated." Seeing Yang Ming's stiff look, Xiao Qing said a little funnyly, "The control authority is all with me, what are you afraid of?" "Your students are all outside, who knows if this room is soundproof or not?" Yang Ming Ming smiled and said.
"Sound insulation? What? Did you ask me for something confidential?" Xiao Qing was a little puzzled, but seeing Yang Ming's obsessed look, she immediately understood the meaning of Yang Ming's words...he meant to talk to herself that? Afraid that the students outside will hear it?
Thinking of this, Xiao Qing's face turned red immediately: "Don't talk nonsense, are you looking for me for anything?"
"Of course." Yang Ming put away his previous smile, carefully took out a mobile phone from his pocket, and placed it on Xiao Qing's desk. It was obtained from that driver, Chen Fansheng.
"What is this?" Xiao Qing looked at Yang Ming suspiciously and asked.
"A encrypted mobile phone is said to be on the possession of a foreign military spy. Let's see if it can be decrypted?" Yang Ming briefly introduced it, and then asked.
"Decipher?" Xiao Qing didn't ask Yang Ming why he wanted to decipher, because there was no need for that, and there was no longer any doubt or doubt about the relationship between the two of them. Xiao Qing gently picked up the phone and checked it. .
After turning on the power of the mobile phone, a prompt to enter the password appeared on the screen. Xiao Qing did not enter it casually, but turned off the mobile phone, opened the back cover of the mobile phone, took out the battery of the mobile phone, and glanced at the back of the mobile phone. mark. Then he said: "Wait, let me check the relevant information of the mobile phone first.
After finishing speaking, Xiao Qing logged into the English website of Google, entered the model number of the mobile phone, and quickly found the search results.
"The third-generation password mobile phone of dcqkrs company, after encryption, can only enter the password three times. After three mistakes, it will execute the self-destruct program, destroy the structure of the flash memory chip, and destroy the data inside. Compared with the second-generation high-voltage wear-and-burn A more powerful generation of products." Xiao Qing looked at the information searched on the computer screen and said: "It is difficult enough to recover data from a burnt flash memory. There are only a few laboratories in the country that can restore data, but this kind of damaged flash memory There is currently no possibility of recovery from the way the chip's physical structure was destroyed."
"That is to say, there is no way to crack it?" Yang Ming asked with some regret after hearing what Xiao Qing said.
"This phone doesn't have any data interface, and it can't communicate with the computer. I don't think there's anything I can do to decrypt it..." Xiao Qing shook her head helplessly.
"But, doesn't this phone have infrared and bluetooth interfaces? Can't it be cracked with these?" Yang Ming pointed to the bluetooth and infrared signs on the phone shell and said, "I read some online novels that said that computer experts Connect directly to the computer with infrared or bluetooth, and the phone can be decrypted!"
"Heh..." Xiao Qing couldn't help but giggled after hearing this, shook her head and said, "Most of the online novels are nonsense, and those authors don't have any computer expertise, so naturally they will mislead you by talking nonsense?"
"How should I say it?" Yang Ming asked curiously.
"You haven't even figured out the most basic principles of mobile phone communication. Indeed, Bluetooth and infrared rays can transmit data, but it can only be done after the mobile phone has activated Bluetooth and infrared rays!" Xiao Qing picked up the mobile phone. The mobile phone said: "Look, this mobile phone stays on the password bar as soon as it is turned on. That is to say, the program in the mobile phone stops after entering the password. If you do not enter the correct password, it will not continue. How can you turn on Bluetooth or infrared without entering the mobile phone interface? "So it's like this..." Yang Ming also studied computer science, so when Xiao Qing said this, he roughly understood: "That is, In other words, just like the wondows operating system, if you don't enter a password when you turn it on, the system cannot be used no matter what you do, right? "
"Almost. But it is easier to crack the password of the computer operating system, and it is much more difficult on the mobile phone." Xiao Qing nodded and said: "Even if you activate infrared or Bluetooth, you are not guaranteed to be able to read the password. Because the infrared and bluetooth functions of the mobile phone only allow file transfer, the function is limited to the application area, and the program area in the mobile phone cannot be operated at all. Therefore, only the data line can be used to operate the program layer in the mobile phone. The computer passes the data The line establishes communication with the CPU of the mobile phone, and directly reads and writes the flash memory, and the operation can be completed without the execution of the program in the mobile phone."
"Ah!" Yang Ming suddenly realized after listening to Xiao Qing's explanation. It turns out that online novels are all lies. Is it possible?"
"You can say that." Xiao Qing nodded. Dao: "However, there is another method, which is to use a programmer to directly read out the content of the flash memory for analysis, but this method obviously does not work. The flash memory chip in this mobile phone is specific, without any model and technical information Outflow, there is no programmer that can support this kind of chip, and even if it is read out, it is hard to say that the program is not encrypted..."
"Okay... It seems that I am a little over my own strength. If I want to come to this kind of encrypted phone produced by a world-renowned company, it is really impossible to crack it." Yang Ming shook his head and said.
"That's not it." Xiao Qing smiled and said: "There are policies at the top and countermeasures at the bottom. The encryption and decryption of computers is an eternal war. It has been fought for many years, but the road is as high as the devil, no matter you What a powerful encryption. There are always hackers cracking it. For example, the Windows operating system of the computer was just released, and hackers cracked it. There are still some video game consoles, etc., which are also being cracked one after another. Some hacker organizations have cracked it. If this mobile phone falls into the hands of those professional hackers, they may be able to figure out a way!"
"Hacker?!" Yang Ming's eyes lit up. What Xiao Qing said is indeed reasonable, in this world. As long as there is encryption, there is decryption. The war between encryption and decryption has been fought for many years, but judging from the update of encryption technology from generation to generation, it can be shown that the previous technologies are not safe.
It is impossible to tell who wins and who loses, maybe the encryption is stronger today, and it will be cracked tomorrow. And the day after tomorrow, a new encryption method appeared again.
When Xiao Qing talked about hackers, Yang Ming suddenly thought of Zhou Jiajia, and didn't Zhou Jiajia say that she knew the king of hackers? If this mobile phone is in her hands, can she think of any way? Maybe she can't figure it out, please, the king of hackers may have a way.
"What? Are you interested in hackers?" Seeing that Yang Ming showed a strange expression when he heard that he said hackers, Xiao Qing asked a little strangely.
