Chapter 1091 Decrypting the mobile phone (Part 2)
Not long after hanging up the phone, an iron door at the end of the corridor opened. Xiao Qing walked out gracefully, wearing a professional suit. Her mature charm made Yang Ming a little impulsive.
"Sorry, I forgot that there is a fingerprint lock!" Xiao Qing apologized to tidy up the hair that had been covered with her head, smiled at Yang Ming, and opened the fingerprint lock.
"It's okay," Yang Ming entered the iron gate and said, "Sister Xiao Qing, you are so beautiful today."
"Don't talk nonsense, there are surveillance here." Xiao Qing glared at Yang Ming and said, "Don't touch me."
"Oh!" Yang Ming naturally saw the camera in the corner of the wall, otherwise he would have hugged Xiao Qing as soon as he came up. After all, he hadn't seen Xiao Qing for a long time.
"What's the matter with me?" Xiao Qing took Yang Ming into his laboratory just now. There was a doctoral student in the laboratory studying something on the computer. Yang Ming took a look, but couldn't understand it. It seemed that he was designing a model of something.
After entering the inner room of the laboratory, this is Xiao Qing's territory. There are no outsiders here, so Xiao Qing naturally would not be polite to Yang Ming. She sat directly on the boss's chair, tilted her head back, and comfortably put her hands on her legs: "I've been exhausted these two days."
Yang Ming sat on the sofa next to him. Because there was a camera here, although he didn't know if it was activated, Yang Ming didn't dare to do it casually.
I think this kind of high-end laboratory will install cameras in order to ensure safety.
"The camera has not been activated." Xiao Qing saw Yang Ming's restrained look and said with some amusement: "The control authority is all here with me, what are you afraid of?" "Your students are all outside, who knows whether this room is soundproof or not?" Yang Ming smiled and said.
"Soundproofing? Why? Do you have any secret matters when you ask me for it?" Xiao Qing was a little puzzled, but seeing Yang Mingse's confused look, she immediately understood what Yang Ming said... He said he wanted to be like himself? Is he afraid that the students outside would hear it?
Thinking of this, Xiao Qing's face suddenly turned red: "Don't talk nonsense, is it okay for you to find me?"
"Of course there is." Yang Ming then put away his previous smile, carefully took out a cell phone from his pocket, and placed it on Xiao Qing's desk. It was brought from the driver Chen Xiansheng.
"What is this?" Xiao Qing looked at Yang Ming in confusion and asked.
"A mobile phone with a secret is said to be a foreign military spy. Look, can it be decrypted?" Yang Ming introduced it briefly and asked.
"Decryption?" Xiao Qing did not ask Yang Ming why she wanted to decrypt it, because there was no need. There was no doubt or doubt about the relationship between the two. Xiao Qing gently picked up her phone and checked it.
After turning on the power of the phone, a prompt for entering a password appeared on the screen. Xiao Qing did not enter it casually, but turned off the phone, opened the back cover of the phone, took out the battery of the phone, looked at the back mark on the back of the phone. Then she said: "Wait for me to check the relevant information about the phone first.
After saying that, Xiao Qing logged into Google's English website, then entered the model of her phone, and soon found the search results.
"Dcqkrs' third-generation password mobile phone, after encryption, can only enter the password three times. After three errors, it will execute a self-destruction program, destroy the structure of the flash memory chip, and destroy the data inside. It is a generation of products that are more powerful than the second-generation high voltage through burning. "Xiao Qing looked at the information on the computer screen and said: "It is difficult to recover data when burned flash memory is difficult to recover. There is only a few laboratories in the country that can recover, but this method of destroying the physical structure of the flash memory chip is currently not possible."
"In other words, there is no way to crack it?" Yang Ming asked with regret after hearing Xiao Qing's words.
"This mobile phone does not have any data interface and cannot communicate with the computer. I should have no choice but to decrypt it..." Xiao Qing shook her head helplessly.
"But, isn't there an infrared and Bluetooth interface on this phone? Can't it be cracked with these?" Yang Ming unwillingly pointed to the Bluetooth and infrared signs on the phone's shell and said: "I read some online novels that computer experts can decrypt the phone by directly connecting to the computer with infrared or Bluetooth!"
"Ha..." Xiao Qing couldn't help but burst into laughter after hearing this, shook her head and said, "Most of the online novels are nonsense, and those authors do not have any computer expertise, so they will naturally mislead you by talking nonsense?"
"How do you say it?" Yang Ming asked curiously.
"You don't even understand the most basic communication principle of mobile phones. Indeed, Bluetooth and infrared can transmit data, but it must be built after the phone starts Bluetooth and infrared!" Xiao Qing picked up the phone on the desk and said, "Look, the phone stays on the password bar as soon as it is turned on. In other words, the program in the phone stops after entering the password. If you don't enter the correct password, you will not continue the subsequent boot command. Moreover, if you don't enter the mobile phone interface, how can you turn on Bluetooth or infrared? "So that's it..." Yang Ming also studied the computer department, so Xiao Qing said so, and he roughly understood: "In other words, just like the wondows operating system, if you don't enter the password, the system cannot use the same principle, no matter how you operate it, right?"
"It's almost the same. However, it's easier to crack the password of the computer operating system, so it's much more difficult on the phone." 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, and the functions are limited to the application area and cannot operate the program area in the mobile phone at all. Therefore, the only data cable can be used for operation on the program layer in the mobile phone. The computer establishes communication with the CPU of the mobile phone through the data cable, and directly reads and writes the flash flash memory. It does not require the execution of the programs in the mobile phone to complete the operation."
"Ah!" Yang Ming suddenly realized after hearing Xiao Qing's explanation. It turned out that online novels are all lie. Although they have gained a lot of knowledge today, Yang Ming was a little depressed: "In other words, it is impossible to decrypt it?"
"It can be said that." Xiao Qing nodded and said, "But another way is to use a programmer to directly read out the content of flash flash memory for analysis. However, this method obviously does not work. The flash flash memory chip in this mobile phone is specifically referring to, and there is no model or technical data outflow, and no programmer can support this chip. And even if it is read out, it is hard to say that the program is not encrypted..."
"Okay... It seems that I'm overestimating my ability. I think there is really no possibility to crack the encrypted phones produced by world-famous companies." Yang Ming shook his head and said.
"That's not." Xiao Qing smiled and said, "There are policies above and countermeasures below. Computer encryption and decryption are eternal wars. It has been fought for many years, but the devil is one foot higher than the top. No matter how powerful the encryption you are, there are always hackers to crack it. For example, the computer's window operating system has just been released, and some video game consoles and so on are cracked by some hackers one after another. If this phone is in the hands of those professional hackers, they may be able to figure out a solution!"
"Hacker?!" Yang Ming's eyes lit up. What Xiao Qing said really makes sense. In this world, as long as there is encryption, there is decryption. The war between encryption and decryption has been fighting for many years. However, from the point of updating encryption technology from generation to generation, it can be seen that previous technologies are not safe.
I can't tell who wins or loses. It may be that encryption is more powerful today, but it will be cracked tomorrow. And the day after tomorrow, new encryption methods appear again.
When Xiao Qing talked about hackers, Yang Ming suddenly thought of Zhou Jiajia. Didn’t Zhou Jiajia say that she knew the king of hackers? If this phone was in her hands, could she come up with something? Maybe she couldn’t think of it, please let the king of hackers have a way.
