So Pure, So Flirtatious

The first thousand and ninety-one chapters decrypt the mobile phone (below)

Not long after the phone was hung up, an iron gate at the end of the corridor opened. Xiao Qing walked out from the inside and dressed in a professional suit. The mature charm made Yang Ming feel impulsive.

"Sorry, I forgot that there is a fingerprint lock!" Xiao Qing apologized for the whole hair on the whole head, smiled at Yang Ming and opened the fingerprint lock.

"It's okay," Yang Ming entered the iron gate and said: "Xiao Qingjie, you look so good today."

"Don't talk nonsense, there is monitoring here." Xiao Qing stunned Yang Ming and said: "Don't move your hands."

"Oh!" Yang Ming naturally saw the camera at the corner of the wall, or she just hugged Xiao Qing as soon as she came up. After all, Xiaoqing was not seen for a long time.

“What are you looking for?” Xiao Qing took Yang Ming into his lab. There was a doctoral student in the lab and studied something on the computer. Yang Ming glanced at it and didn’t understand it. It seemed to be redesigning something. Model.

Into the laboratory's inner room, this is Xiaoqing's site, there is no outsider here, Xiao Qing naturally will not be polite to Yang Ming, directly sitting on the boss's chair, head backwards, comfortable will Put your hands on your lap: "In these two days, you will be exhausted."

Yang Ming sat on the sofa next to it, because there is a camera here, although I don't know if it started, but Yang Ming did not dare to make it casually.

I want to come, this high-end laboratory, in order to ensure safety, will install a camera.

"The camera didn't start." Xiao Qing looked at Yang Ming's cautious look. Some funny said: "The control rights are all here. What are you afraid of?" "Your students are outside, who knows that this room is soundproof and not soundproof?" Ming smiled and said.

"Soundproof? How? Do you find anything confidential about me?" Xiao Qing was puzzled, but looking at Yang Ming’s fascination, he immediately understood the meaning of Yang Ming’s words... He said that he wanted to be with himself. That? Afraid of the students outside to hear?

Thinking of this, Xiao Qing’s face suddenly became red: “Don’t talk about it, are you looking for me?”

"Of course." Yang Ming put away the previous smile, carefully took a mobile phone out of his pocket and placed it on Xiao Qing's desk. It was from the driver Chen Fansheng.

"What is this?" Xiao Qing looked at Yang Ming with a puzzled look and asked.

"A mobile phone with a secret is said to be a foreign military spy. You can see if you can decrypt it?" Yang Ming introduced it briefly and then asked.

"Decryption?" Xiao Qing did not ask why Yang Ming wanted to decrypt, because there was no need for it. There was no doubt or doubt about the relationship between the two people. Xiao Qing gently picked up the mobile phone and checked it up. .

After turning on the power of the mobile phone, the prompt for entering the password appeared on the screen. Xiao Qing did not input 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. Standard. Then said: "When I first check the information about the phone.

After that, Xiao Qing landed on Google's English website, and then entered the model of the mobile phone, and soon found the search results.

"The third-generation password mobile phone of dcqkrs company can only input three passwords after encryption. After three errors, it will execute the self-destruction program, destroy the structure of the flash memory chip, destroy the data inside, and destroy the higher voltage than the second generation. A more powerful generation of products. "Xiao Qing looked at the information on the computer screen and said: "The burned flash memory is hard enough to recover data. Only a few labs in the country can recover, but this kind of destruction flash The destruction of the physical structure of the chip is currently not possible."

"That is, there is no way to crack it?" Yang Ming listened to Xiao Qing and said, some regretted.

"This mobile phone does not have any data interface, and can't communicate with the computer. There is no way to decrypt it." Xiao Qing shook his head helplessly.

"But, there is no infrared or Bluetooth interface on this phone? Can you use these to crack?" Yang Ming said with a blue and infrared logo on the phone case: "I see some online novels, computer masters. You can decrypt your phone by connecting it directly to your computer with infrared or Bluetooth!"

"Oh..." Xiao Qing couldn't help but smile and shook his head and said: "Most of the online novels are nonsense. Those authors don't have any computer expertise. Naturally, they will mislead you?"

"How do you say that?" Yang Ming asked curiously.

"You don't even know the basic mobile phone communication principle. Indeed, Bluetooth and infrared can transmit data, but it must be built after the phone starts Bluetooth and infrared!" Xiao Qing picked up the table. The mobile phone said: "Look, this mobile phone stays on the password bar when it is turned on. That is to say, the program in the mobile phone stops after entering the password here. If you do not enter the correct password, it will not continue. The boot command, and you do not enter the phone interface, how can you boot Bluetooth or infrared? "It turned out to be like this..." Yang Ming is also studying computer science, so Xiao Qing said so, he roughly understood: "that is Say, just like the wondows operating system, you don't enter a password when you boot, no matter how you operate, the system can't use a reason, right? ”

"Almost. But the password of the computer operating system is much simpler to crack, and the phone is much more difficult." Xiao Qing nodded and said: "Even if you start infrared or Bluetooth, you can't 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 operated on the program layer in the mobile phone at present. The line and the mobile phone's cpu establish communication, directly read and write the flash flash memory, and can complete the operation without the execution of the program in the mobile phone."

"Ah!" Yang Ming listened to Xiao Qing's explanation before he realized that the original online novels were deceptive. Although he has a lot of knowledge today, Yang Ming is somewhat frustrated: "That is, when you want to decrypt, Is it possible?"

"You can say that." Xiao Qing nodded. Dao: "But there is another way to use the programmer to directly read the contents of the flash memory for analysis. However, this method obviously does not work. The flash memory chip in this mobile phone is specifically referred to, without any model and technical information. Outflow, no programmer can support this chip, and even if it is read out, the program is not encrypted and it is hard to say..."

"Well... It seems that I am a little self-sufficient. I want to come to an encrypted phone produced by such a world-famous 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 countermeasures under the policy. Encryption and decryption of computers are eternal wars. It has been playing for many years, but the height of the road is one foot high, no matter you. How powerful is the encryption. There are always hackers to crack it. For example, the computer's Windows operating system, just released, there are hackers to crack it, and the rest are some video game consoles, etc., are also being successively Some hacker organizations have cracked it. If the phone is in the hands of professional hackers, it is estimated that they may come up with a way!"

"Hacker?!" Yang Ming shines. Xiao Qing said that there is truth in this world. As long as there is encryption, there is decryption, encryption and decryption. This war has been going on for many years, but from the point of view of the generation of encryption technology, it can be shown that the previous technology is not safe.

Can't tell who wins and who wins, maybe today is more powerful encryption, tomorrow is cracked. And the day after tomorrow, new encryption methods have emerged.

When Xiao Qing talked about hackers, Yang Ming suddenly thought of Zhou Jiajia, and Zhou Jiajia did not say that she knew the king of hackers? If the phone is in her hands, can she figure out what to do? Maybe she can't think of it, maybe the king of hackers may have a solution.

"How? You are interested in hackers?" When Yang Ming heard that he said that he was a hacker, he showed a strange expression. Xiao Qing asked strangely.
