"That's not it … It's just that I have a friend who knows more about hacking. I want to see if she has a way." Yang Ming didn't hide it from Xiao Qing.
"That's fine." Xiao Qing nodded and didn't ask much. After all, the identity of many hackers couldn't be exposed, so she changed the topic and continued, "It's better to try than to do nothing. Right, did the jewelry exhibition go well? I read in the newspaper … "
The previous Zhuang Jingtian robbery case had already been reported in the newspaper. Although Chen Fei had tried to downplay the matter at the request of Yang Ming, there were many parties present that day, and it still alarmed the media. However, at the request of Chen Fei, Yang Ming's identity was kept secret. After all, Chen Fei didn't provide information. The media couldn't investigate it even if they were powerful. Therefore, the newspaper only briefly reported the bank robbery case and the news that all the perpetrators were arrested.
"I read in the newspaper that the second day of the exhibition was robbed, right?" asked Xiao Qing. When the report just came out, Xiao Qing was doing an experiment. When she got the news, it was already a few days later. She knew from Sun Jie that Yang Ming was fine, so Xiao Qing didn't bother Yang Ming again. However, now that she met Yang Ming, she naturally had to ask.
"Hehe, it's nothing. It's just a few gangsters who overestimated themselves. They were quickly subdued." Yang Ming tried to be as indifferent as possible and didn't involve himself in it.
"En, I believe in your ability." Xiao Qing was still very assured about Yang Ming's ability to adapt. After all, every time she was with Yang Ming, Yang Ming could be calm and turn the situation around.
"Hehe, what kind of ability are you talking about?" Yang Ming asked with a smirk.
"Annoying!" Xiao Qing blushed and said. It was rare for her to show the attitude of a little girl.
Yang Ming also knew that this was a laboratory. He couldn't do whatever he wanted. Some things were just a matter of words.
"You seem to be very busy recently?" Yang Ming saw that there was even a bed in Xiao Qing's laboratory, and the quilt had traces of being moved. It was obvious that Xiao Qing had slept here, so he asked.
"En, I have been researching a new model of network transmission protocol recently. It is jointly developed with the laboratories of several famous universities in the world. I often sleep here in the laboratory," said Xiao Qing.
"Will you be busy for a long time?" Yang Ming stepped forward and touched Xiao Qing's hair. He said, "It's easy to age if you stay up late. Try to get your subordinates to do it. You just have to command them."
"Heh …" Xiao Qing smiled after listening. "You are bad enough to make others stay up late."
"It's fine for those university students to stay up late," Yang Ming said with a smile. "But you, if you don't take care of yourself, be careful that I don't want you."
Xiao Qing naturally knew that Yang Ming was just joking. Moreover, Xiao Qing herself was very careful about taking care of herself. She rolled her eyes at Yang Ming and said, "The age of the PhD student is about the same as mine …"
"Hehe, I'm just saying. Then I won't bother you for a while. When you are done, contact me." Yang Ming picked up the phone on the table, put it in his pocket, and said.
"Right, Yang Ming, that mobile phone is classified as a confidential device overseas. You should be careful when you hold it. Don't let anyone with bad intentions see it. Don't tell your friends that you don't trust …" Xiao Qing hesitated. "If your relationship with your hacker friend isn't very good … it's best not to say it, so as not to cause unnecessary trouble."
Xiao Qing was very proficient in technology. She also knew the consequences of this advanced technology. Since Yang Ming wanted to decrypt this phone, then this phone must not be obtained through normal channels. If it was publicized, it would inevitably cause a storm.
"That friend of mine can still be trusted." Yang Ming listened to Xiao Qing's words and smiled. Yang Ming also knew that Xiao Qing was worried about him. After all, there was nothing wrong with being careful.
"En, then I won't say anything else. It's hard to know what's in a person's heart. You should be careful." Xiao Qing said.
"Ha, Sister Xiao Qing, why don't I tell the truth …" Yang Ming saw that Xiao Qing was worried about him, so he simply confessed, "The relationship between that friend and me is just like how you treat me … She won't betray me …"
Xiao Qing was stunned, and then she understood the meaning of Yang Ming's words. Her face turned red and said, "Have I seen her before?"
"You should have seen her before. That time at the entrance of the restaurant, Zhou Jiajia." Yang Ming said, "My classmate …"
"En, it's easy to say that she is one of us. At least she won't betray you." Xiao Qing nodded and no longer asked anything.
After leaving Xiao Qing's laboratory, Yang Ming returned to the car and called Zhou Jiajia immediately. This kind of problem of decryption, Zhou Jiajia should be more professional! Although Xiao Qing was a master in the field of computer science and even participated in the formulation of some agreements, when it came to these peripheral technologies, she didn't know as much as Zhou Jiajia. After all, Xiao Qing was exposed to some formal technologies, unlike Zhou Jiajia who specialized in these peripheral technologies.
"Yang Ming?" Zhou Jiajia received a call from Yang Ming, and she was obviously very happy. She also knew that Yang Ming was busy with the jewelry exhibition with Chen Mengyan and Lin Zhiyun, but Zhou Jiajia felt a little regretful that she couldn't attend it together.
However, she didn't know much about jewelry. Although Chen Mengyan also invited her to go together, Zhou Jiajia was afraid that she wouldn't be able to help and would cause more trouble, so she declined and stayed at school.
"Jiajia, where are you?" Yang Ming naturally felt Zhou Jiajia's excitement at the moment, and he was slightly embarrassed. Sometimes, just a phone call would make this girl happy.
"I'm at school. What about you? Are you done with the exhibition? "asked Zhou Jiajia.
"En, the exhibition is over. I'm also at school. Do you have time in the evening? Let's have dinner together." Yang Ming looked at the time, and it was basically dinner time.
"Of course, I do. When? Now? " Zhou Jiajia had already made an appointment with Wang Xue to eat in the cafeteria, but since Yang Ming called, Zhou Jiajia naturally left Wang Xue behind. Wang Xue, who was on the side, listened to Zhou Jiajia's words, and she was so angry that she pouted.
"Now is fine. I'll wait for you at the school gate." Yang Ming said.
A few minutes later, Zhou Jiajia came to the school gate. Wang Xue had already gone to find Yang Ming. Although Zhou Jiajia felt that it was inappropriate for her to do so, she hadn't seen Yang Ming for a long time. Zhou Jiajia had to make a decision to value a lover over a friend …
Zhou Jiajia got in the car and sat in the front passenger seat. Chen Mengyan and Lin Zhiyun weren't there, so Zhou Jiajia could naturally relax.
"Where are we going to eat?" Yang Ming waited for Zhou Jiajia to get in the car and started the car.
"Anything is fine. We can eat anything. Or, we can buy something to eat at home. It's quite cold outside." Zhou Jiajia thought about it and said.
"Then let Aunty Li make something. There should be ingredients at home." Yang Ming said, "I will inform Aunty Li and let her prepare some dishes."
Sure enough, Yang Ming called home and confirmed with Aunty Li that there were indeed a lot of ingredients at home. She could prepare some dishes directly.
Yang Ming instructed Aunty Li to simply prepare two home-cooked dishes because there were only him and Zhou Jiajia. If there were too many dishes, they wouldn't be able to finish it. Chen Mengyan and Lin Zhiyun returned to the company together to help Zhang Bin and Zhao Sisi check the accounts and deal with some large orders received at the exhibition because the jewelry exhibition had just ended. They would probably be busy these few days.
There was also a temporary dormitory in the company. Lin Zhiyun and Chen Mengyan could also sleep together.
The school was very close to the Huashang District where their home was located. Yang Ming and Zhou Jiajia returned home after parking the car. Aunty Li just began to prepare. When she saw that Yang Ming and Zhou Jiajia came back so quickly, she said with some embarrassment, "Mr. Yang, Miss Zhou, I just started preparing … I didn't know that you would come back tonight, so I didn't prepare in advance … It seems that I have to wait for a while …"
"It's okay. We aren't too hungry. Aunty Li, you can take your time. Don't worry." Yang Ming waved his hand and smiled.
"That's good …" Aunty Li nodded and said, "There are fresh bamboo shoots and cabbage in the refrigerator at home. I will make a bamboo shoot meat and a stir-fried cabbage. Is that okay?"
"Okay, Aunty Li, you can prepare as you see fit. Jiajia and I aren't picky." Yang Ming said, "Let's go up and study something first. After the meal is ready, you can inform us with the internal phone. Call the phone in my small bedroom."
"Okay, Mr. Yang, Miss Zhou, you can go ahead." After Aunty Li finished speaking, she went into the kitchen again.
Zhou Jiajia apparently misunderstood Yang Ming's words. When she thought of being kissed and hugged by Yang Ming before, her heartbeat couldn't help but accelerate. Previously, Chen Mengyan and Lin Zhiyun were there, so Yang Ming wouldn't do anything to her. But now that both of them weren't there, there was only herself and Yang Ming, so Zhou Jiajia would inevitably think more.
However, although Zhou Jiajia's heart was somewhat perturbed, she didn't reject these things in her heart. She was just a little reserved on the surface. She went up to the second floor with Yang Ming and entered Yang Ming's small bedroom. Seeing that Yang Ming was sitting on the bed, Zhou Jiajia didn't know what to do.
"Sit?" Yang Ming naturally didn't think so much. When he saw that Zhou Jiajia was still standing, he suddenly felt a little strange, so he waved to her. "Why are you standing? This is your own home. Why are you so restrained? "
"Oh …" Zhou Jiajia blushed and carefully sat next to Yang Ming. However, there was a little expectation in her heart.
Yang Ming looked at Zhou Jiajia's appearance. At first, he was surprised, then he immediately understood why Zhou Jiajia was like this. He naturally reached out and held Zhou Jiajia's soft body in his arms. Zhou Jiajia didn't struggle and fell into Yang Ming's arms.
"My dear Little Jiajia, did you miss your husband these days?" Yang Ming saw Zhou Jiajia's shy look and couldn't help but tease her.
"Ah …" When Zhou Jiajia heard Yang Ming say this, she immediately felt embarrassed. "Aren't we boyfriend and girlfriend first … I haven't become your husband yet …"
"It's the same. There's no difference." Yang Ming said shamelessly, "Could it be that you don't want me to be your husband?"
"Where … Of course not …" Zhou Jiajia quickly shook her head to deny it.
Looking at Zhou Jiajia's cute appearance, Yang Ming couldn't bear to tease her anymore. He gently lowered his head. Zhou Jiajia seemed to realize something. Her body trembled slightly, and she closed her eyes. However, her eyelashes were still trembling. Obviously, her mood was not calm.
Yang Ming gently kissed Zhou Jiajia's lips. It wasn't the first time that Zhou Jiajia kissed Yang Ming, but she was bold enough to take the initiative before, but now she was a little embarrassed.
The two times at the resort and the cinema at the class reunion, Zhou Jiajia was stunned. She even forgot to be shy, but this time was different. Even if Yang Ming was already her boyfriend, Zhou Jiajia was still a little shy.
However, when Zhou Jiajia adapted, she took the initiative to cooperate boldly.
Although Chen Mengyan and Lin Zhiyun weren't at home, Yang Ming didn't want to "f * ck" too much. After all, if he proposed it, Zhou Jiajia wouldn't refuse. However, Yang Ming felt that it was better for them to take it step by step. Otherwise, Zhou Jiajia's heart would definitely have regrets.
After the long kiss, Yang Ming didn't do any other excessive actions. Zhou Jiajia's mood also calmed down. She leaned on Yang Ming's arms and enjoyed the warmth at the moment.
"Jiajia, do you know anything about mobile phone password decryption?" Yang Ming almost forgot about the business. Originally, he called Zhou Jiajia upstairs to talk about the mobile phone, but Zhou Jiajia's charming appearance made him a little distracted. He put the mobile phone matter aside. He was afraid that he would do other things in a while and forget about the mobile phone, so he quickly talked about the business.
"Mobile phone decryption?" Zhou Jiajia nodded after listening, but she asked curiously, "I know a little. Is your mobile phone locked?"
"It's not my mobile phone. It's someone else's mobile phone." Yang Ming handed the mobile phone from the driver, Chen Sisheng, to Zhou Jiajia from his pocket. "I checked on the Internet. This is the latest third-generation encrypted mobile phone launched by the DCIKRS company …"
"En, I have heard of this DCIKRS company. I have also seen the news that they launched the third-generation encrypted mobile phone, but I didn't have this mobile phone in my hand, so I didn't do any research … It turns out that this is the third-generation encrypted mobile phone!" Zhou Jiajia took the mobile phone from Yang Ming's hand with some surprise and said, "The mobile phone that will activate the self-destruct program if the password is wrong three times, right?"
Yang Ming nodded and said, "Yes, it's that one. Do you have a way to decrypt it?"
"I'm not sure now … but I can try." Zhou Jiajia held the mobile phone in her hand, looked at it briefly, and said.
"You … really have a way?" Yang Ming was pleasantly surprised after listening to Zhou Jiajia's words. Even Xiao Qing was sentenced to death, but Zhou Jiajia actually said that she could try it, which meant that there was still hope. However, Yang Ming reminded, "This mobile phone has no data interface to communicate with the outside world, and it is said that the flash memory chip is also specially made. It can't be read and written by normal means …"
"This is not the main problem." Zhou Jiajia shook her head and said, "There is no data interface. You can find the JTAG point to communicate with the CPU on the motherboard of the mobile phone and complete the reading and writing in the form of a fly line. Even if there is no chip data, you can analyze the JTAG point from the peripheral circuit by measuring the connection line between the CPU and the library chip on the motherboard, which is the flash memory … But the key problem is that even if the data is read, the password inside is likely to be in an encrypted form. This is equivalent to wasting your efforts because you don't know the CPU data. There is no way to simulate the mobile phone's program in the computer. If you can simulate it, you can use the dictionary to crack the password …"
Yang Ming could understand what Xiao Qing said. After all, it was the orthodox knowledge of computer science. However, the technology that Zhou Jiajia said was somewhat marginalized, which gave Yang Ming a headache. At least, he didn't know what the JTAG was.
"That means the hope of cracking it is relatively slim?" Yang Ming didn't quite understand, but he could still understand the meaning expressed by Zhou Jiajia.
"That is not the case." Zhou Jiajia said, "There is a more troublesome way, which is to use the hardware platform of the mobile phone itself and combine it with the computer to complete the cracking. It can be achieved from a technical point of view."
"How do you say that?" Yang Ming heard that there was a way, so he asked quickly.
"No matter how it is encrypted, what algorithm is used, even if there is no way to reverse the algorithm, when you enter the password, the program will compare this password with the correct password. Even after tens of thousands of encryption, there is a comparison process. After the comparison, the program will perform a judgment and jump. If the password is correct, it will run the boot program. If the password is wrong, it will record the number of errors in the information area of the mobile phone. Once this number is equal to three, it will start the self-destruct program. After knowing the operating principle of this mobile phone, it is still possible to crack it. "Zhou Jiajia explained," In this way, there are two ways to crack it. "
"Two?" Yang Ming was a little surprised after hearing it. It was not easy to crack it, but Zhou Jiajia actually gave two solutions.
"Hehe, it's just two solutions. Whether they can be implemented successfully is another problem." Zhou Jiajia shook her head and said, "I just analyzed it from the common cracking ideas. The first one is relatively simple, but the risk is high. Find a way to find the communication point of JTAG, read the program in the mobile phone, and then enter the wrong password. Then, write the previously read program into the mobile phone, cover the mark of the password error, and let the program return to its original state. Although this approach seems simple, we don't know if it will cause any adverse reactions because we don't understand the structure of the mobile phone. We don't know if the number of errors in the password is written in the Flash chip of the mobile phone, the CPU, or other chips. If it is written in other chips, we can't achieve the purpose of recovery. Instead, it may directly cause the mobile phone to start the self-destruct program because the error information in the program and other hardware is inconsistent … "
