So Pure, So Flirtatious

The first thousand and ninety-two chapters of Zhou Jiajia's approach (below)

Zhou Jiajia obviously misunderstood Yang Ming’s words. When she thought of being kissed by Yang Ming, her heartbeat could not help but accelerate. Before, there were Chen Mengyu and Lin Yuyun, Yang Ming would not be like her, but now neither of them is in Only Yang and Yang Ming are left, and Zhou Jiajia will inevitably think more.

However, Zhou Jiajia's heart is a bit embarrassing, but in the bottom of his heart, it does not exclude these things, but some face-to-face support, and Yang Ming went up the second floor, entered Yang Ming's small bedroom, and saw Yang Ming sitting. On the bed, Zhou Jiajia did not know how to be good.

"Sit?" Yang Ming did not think so much. Seeing that Zhou Jiajia was still standing, it was a bit strange, so she waved her hand: "What are you doing? This is your own home, so restrained?"

"Oh..." Zhou Jiajia reddened his face and carefully sat next to Yang Ming. However, his heart was a little anticipation.

Yang Ming looked at Zhou Jiajia's appearance. First, it was a strange one. Then he immediately understood why Zhou Jiajia was like this. It was natural to reach out and put Zhou Jiajia's soft body in his arms. Zhou Jiajia did not struggle, and the homeopathic fell. Yang Ming’s arms.

"Kissing Xiao Jiajia, have you been thinking about my husband these days?" Yang Ming saw Zhou Jiajia's shy look and couldn't help but tease her.

"Ah..." Zhou Jiajia listened to Yang Ming, saying that he was embarrassed at the moment: "Isn’t it a boyfriend or a friend... I haven’t become a husband yet...”

"It's the same, there is no difference." Yang Ming said with a big say: "Do you want me to be your husband?"

"Which is... of course not..." Zhou Jiajia quickly shook his head and denied it.

Looking at Zhou Jiajia's cute look, Yang Ming couldn't bear to tease her again. She lowered her head gently. Zhou Jiajia seemed to realize something. When she was slightly trembled, she closed her eyes, but the eyelashes were still shaking. Obviously, the mood was very Not calm.

Yang Ming gently kissed Zhou Jiajia's lips, Zhou Jiajia was not the first time to kiss Yang Ming, but he was bold and active before, but now it is a bit embarrassing.

At the classmate's resort and movie theater twice, Zhou Jiajia was stupid, some stunned, and even forgot the shame, but this time it is different, Rao is Yang Ming is her boyfriend, Zhou Jiajia Still a little shy.

However, when Zhou Jiajia got used to it, he took the initiative and boldly cooperated.

Although Chen Mengxi and Lin Yuyun are not at home, Yang Ming does not want to be too hasty. After all, if he proposes it, Zhou Jiajia will not refuse it. It is just that Yang Ming thinks that the two are better step by step, otherwise Zhou Jiajia will definitely regret it.

After the long kiss, Yang Ming did not do other excessive fires. Zhou Jiajia’s emotions calmed down, relying on Yang Ming’s arms to enjoy the warmth of the moment.

“Jia Jia, do you know something about the decryption of the mobile phone password?” Yang Ming almost forgot about the business. I just called Zhou Jiajia upstairs to talk about the mobile phone, but it was made by Zhou Jiajia’s charming look. I left the mobile phone thing aside, I was afraid that I would do other things for a while, and I forgot my mobile phone, so I quickly said something right.

“Mobile phone decryption?” Zhou Jiajia nodded after listening, but some strangely asked: “Know some, is your phone locked?”

"Not my mobile phone, it is someone else's mobile phone," Yang Ming handed the mobile phone from the driver Chen Yusheng in his pocket to Zhou Jiajia: "I have queried it online, this is the latest launch of dcikrs. Third generation encrypted mobile phone..."

"Well, I have heard of this dcikrs company. I have seen the news of their third-generation encrypted mobile phones. However, there is no such mobile phone in hand, so there is no research... This is the third-generation encrypted mobile phone!" Zhou Jiajia Some surprised that I took the phone from Yang Ming and said, "Three times the password error will start the self-destruction program, right?"

Yang Ming nodded and said: "Yes, that is the one, can you decrypt it?"

"Now I am not sure... but you can try it." Zhou Jiajia took the phone in his hand and looked at it briefly, then said.

"You... really have a way!" Yang Ming listened to Zhou Jiajia's words and suddenly had some surprises. Even Xiao Qing had sentenced the death penalty. Zhou Jiajia actually said that he could try it, and that means there is hope. However, Yang Ming reminded: "This mobile phone does not have a data interface to communicate with the outside world, and it is said that the flash memory chip is also specially made and cannot be read and written by normal means..."

"This is not the main problem," Zhou Jiajia shook his head and said: "Without a data interface, you can find the jtag point that communicates with the CPU on the motherboard of the mobile phone, and read and write in the form of a flying line. Even if there is no chip data, pass the The CPU and font chip on the motherboard are also the measurement of the communication line between the flash memory, and the jtag point can be analyzed from the peripheral circuit. However, the key problem is that even if the data is read, the password inside is likely to exist in encrypted form. This is equivalent to in vain, because I don't know the information of the cpu, there is no way to simulate the running of the mobile phone in the computer. If you can simulate it, you can hang the dictionary and hack the password..."

Xiao Qing said that Yang Ming can still understand, after all, it is the orthodox knowledge of computers, but Zhou Jiajia said that these technologies are somewhat marginalized, so that Yang Ming is very big, at least what jtag he does not know is what.

"That is to say, the hope of cracking is more awkward?" Although Yang Ming did not understand, but Zhou Jiajia expressed his meaning, he could still understand.

“It’s not like this,” said Zhou Jiajia. “There is still a more troublesome way to use the hardware platform of the phone itself to complete the crack together with the computer, which can be achieved from a technical perspective.”

"How do you say that?" Yang Ming heard that there was still a way, so he quickly asked.

"No matter how encrypted he is, 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. After comparison, there is also a process of comparison. After the comparison, the program performs a judgment and jump. If the password is correct, the boot program is run. If the password is wrong, the number of errors is recorded in the information area of ​​the mobile phone. When this number is equal to three, the self-destruction program is started. 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 solutions for cracking.”

"Two?" Yang Ming was a little surprised when he heard it. It was not easy to crack it. Zhou Jiajia actually gave two plans.

"Oh, it’s just two programs. Can you implement success or another problem?" Zhou Jiajia shook his head and said: "I just analyzed it from the commonly used hacking ideas. The first one is relatively simple, but the risk is assumed. Very big. Find a way to find the jtag communication point, read the program inside the phone, and then enter the wrong password, then write the previously read program to the phone, overwrite the record password error mark, let the program restore the initial state Although this method seems simple, it does not know whether it will cause any bad reaction, because we do not understand the structure of the phone, do not know the number of times the password is wrong is written in the flash chip of the phone or written in Inside the cpu or other chips, if written in another chip, we can not do the purpose of recovery, but may be caused by the inconsistency between the program and other hardware errors, directly let the phone start the self-destruction program...... ”
