"Ah? Can information be written into other hardware?" Yang Ming originally only knew how to use a mobile phone. so difficult.
"Of course." Zhou Jiajia nodded and said, "Don't talk about these professional encrypted mobile phones for military use, let's talk about our civilian mobile phones, such as the Nokia mobile phones you and I use. The power supply of the mobile phone participates in the encryption."
"Power supply?" Yang Ming was confused.
"It's the uem power manager chip in the mobile phone. You know that every mobile phone has an imei code?" Zhou Jiajia said: "Nokia's imei code is not only in the flash memory font, but also in the power chip. There are only two When the two codes are the same, the mobile phone will run normally, otherwise there will be a prompt that the mobile phone is restricted or two lines of English. And the power chip is written once and cannot be changed, that is to say, if your encrypted mobile phone uses a similar The technology of writing each password error information into other chips, and if it is not erasable, the method mentioned before is meaningless.”
Yang Ming nodded, and he roughly understood what Zhou Jiajia said. Although Yang Ming didn't know the specific function of the uem chip, Yang Ming could still understand the role it played in encryption: "In addition One way?"
"The other method is more reliable, but it is more complicated to implement." Zhou Jiajia said: "The other method is actually what I said just now, that is to cooperate with the computer to perform simulation operations on the hardware of the mobile phone, but to realize the integration between the mobile phone and the computer." The communication aspect is more complicated, because there is no debugging interface, it can only be inferred from the peripheral circuit. If the contact that can be debugged is really found, then the mobile phone may be decrypted. The specific operation method is to execute the program that verifies the password on the mobile phone. Finally, the computer sets a breakpoint to keep the program in an interrupted state, that is to say, the program is forcibly interrupted before the program jumps to the step of writing error information. Of course, it is also possible that the program has the function of anti-debugging, so you can only Cut off the power to cut off the writing operation of the mobile phone. If this method is used properly, the real password can be cracked by brute force. This is the way I plan to try. "
"Okay, then do it according to your method." Yang Ming nodded and said, "I hope it can be successful."
"I will publish some information and pictures of this mobile phone in our hacker circle. It may be faster if everyone can study together. You don't mind?" Zhou Jiajia asked Yang Ming for his opinion.
"It doesn't matter, but people won't ask you where you got this thing from, right? It won't cause any trouble, right?" Yang Ming reminded.
"That's not true!" Zhou Jiajia shook her head and said, "The hacker organization is an organization that is on the edge of the law, so the people in the organization often come up with some weird things for everyone to study together, and everyone will not Ask how this thing came about."
Yang Ming nodded and felt relieved. He didn't understand some rules in the hacker world, and each hacker organization's rules were different, so Yang Ming couldn't understand it. It's like Zhou Jiajia also doesn't understand the rules of the killer world.
The mobile phone was left with Zhou Jiajia, and Aunt Li also called, saying that dinner was ready, and asked Yang Ming and Zhou Jiajia to go down to eat, so the two tidied up the messy clothes they had messed up during the kiss before, and went downstairs.
Aunt Li's workmanship is quite good, but according to herself, before becoming a nanny, the housekeeping company gave them a centralized training, so it's not a big deal.
But Yang Ming thinks that if Aunt Li doesn't have that talent, it's useless to learn. So many people go to chef school to learn, but there are only a few people who can be top chefs. Therefore, learning is one aspect, personal Understanding is also very important.
A plate of fried pork with bamboo shoots, and a plate of fried cabbage, two very ordinary home-cooked dishes, but under the hands of Aunt Li, they became delicious in color and flavor. style. Aunt Li's dishes tend to be spicy, while Chen Mengyan's dishes tend to be light, each has its own merits.
Yang Ming and Zhou Jiajia were naturally full of praise for what they ate.
Today is not Saturday, Yang Ming wanted to keep Zhou Jiajia at home, but because the girls' dormitory check was very strict not long after school started, so after dinner, Yang Ming drove Zhou Jiajia back to school.
"Are you in a hurry about the phone?" Zhou Jiajia asked before getting out of the car.
"Don't worry, you can fix it when you have time, you don't need to study it specially." Yang Ming said. After all, Yang Ming didn't have any hope at first, but Zhou Jiajia said that it was possible to solve it, but Yang Ming didn't want Zhou Jiajia to delay his normal study and life because of this phone.
Seeing Zhou Jiajia enter the women's dormitory, Yang Ming started the car, not knowing where to go. Young Master Tian and Wang Xue went there. Zhou Jiajia is the class leader and must lead by example, but Wang Xue has no need for that. Even if he is not in the dormitory, it doesn't matter if he is caught by the instructor.
Anyway, Tian Donghua is already registered in the school, and his girlfriend is Wang Xue, and the teachers in the department know it, so there are no particularly strict requirements.
And Zhang Bin, Zhao Sisi, Chen Mengyan, and Lin Zhiyun went to work in the jewelry company. Zhao Sisi, Chen Mengyan and Lin Zhiyun have already asked for leave due to company affairs and school, so it doesn't matter if they are not in the dormitory. Nowadays, universities basically encourage students to find employment and start a business in advance. After all, the purpose of going to university is to find a job after graduation, and capable students can find employment or start a business before graduation. The school also reduces the pressure of public opinion on employment. , It's also good-looking, so after Zhao Sisi and the others submitted the leave note with the company's official seal, the school leaders naturally approved it.
It was not interesting for Yang Ming to go back to the school dormitory, nor was it interesting to go home. Xiao Qing did another experiment, and Yang Ming experienced for the first time the feeling of being lonely when there are many women.
Picking up the phone, Yang Ming called Sun Jie to see if she was there, so he happened to give her a piece of jewelry. Because of Xie Wenjin and Qi Zhide's incident, Yang Ming's mood was messed up, so he gave Xiao Qing's He also forgot the gift in the car and didn't take it up. He also forgot what he wanted to give to Zhou Jiajia, and he didn't remember it until now.
But neither Zhou Jiajia nor Xiao Qing are outsiders, and it doesn't matter what time they give.
"Dear little Jiejie, where are you?" Yang Ming called Sun Jie.
"Ah...uh...Yang Ming, I'm Sun Hongjun..." Sun Hongjun heard his daughter's phone ring in the living room, picked it up and saw Yang Ming's name was written on the caller ID, so he picked it up When I got up, I didn't expect Yang Ming to say such nasty and ambiguous words in the first sentence, which made Sun Hongjun feel a little hot, and thought in his heart, he really shouldn't answer this call, and he should listen to the sweet talk between young people. What!
"Hey!" Yang Ming was stunned for a moment, and then he felt a little ashamed. Sun Hongjun answered the call to Sun Jie before, and this time he answered the call again. Yang Ming said in embarrassment: "Uncle Sun, that , where is Xiaojie?"
"Xiaojie came back by car in the afternoon. She talked with me for a while. She was a little sleepy, so she went upstairs to rest. She forgot her phone in the living room. Do you have anything urgent to do with her?" Sun Hongjun asked.
"Uh... nothing urgent, just a casual phone call..." Yang Ming thought, I can't say that I want your daughter to sleep with me, can I? Besides, Sun Jie has returned to Donghai, and she can't accompany her if she wants to.
"Well... that's it. By the way, you don't know about Xiaojie's return to the East China Sea?" Hearing Yang Ming's tone, Sun Hongjun didn't seem to know about Sun Jie's return to the East China Sea.
"In the past few days, I've been busy with the Songjiang Jewelry Fair, so I haven't contacted Xiaojie. No, I only called her after the fair was over," Yang Ming said.
"Ha, so, I've also heard that the fair is organized by your famous security company, and the matter has been handled very satisfactorily, not bad!" Sun Hongjun praised after hearing this.
"Well, it's quite satisfactory. I called Xiaojie to talk about this matter." Yang Ming said, "Since she's asleep, let's forget it."
"After she wakes up, I'll ask her to call you back." Sun Hongjun said, "Come over to Donghai to play when you have time?"
"Uncle Sun, you see, I'm so busy every day, how can I have time..." Yang Ming smiled wryly.
"That's right. In our position, there are always a lot of chaos every day." Sun Hongjun thought it was true.
Yang Ming sweated profusely, thinking, when did I become equal to you, and my status has been improved?
"That's fine, let's do this first, let Xiaojie contact me when she wakes up." Yang Ming said.
"Okay, I'll tell her when she wakes up and ask her to call you back." Sun Hongjun nodded.
