Coquettish Rebirth

Under Jia Hongjian's exaggeration, the so-called prov code compiled by the so-called cicr technology is simply too good. Basically, no method on the market can crack it now. Jia Hongjian even promised that if Sony is worried about providing it to others If the same prov code is leaked and Sony is damaged, Huaxia Hi-Tech can immediately develop a version of the key code that is confidential and specially made for Sony within 10 days after signing the contract

What does it mean?That is to say, the widely provided prov codes are all calculated with the same algorithm. If a vendor gets the key—that is, the cracking method at the broken end, it can smoothly crack all the discs that use this universal password. However, if Huaxia Hi-Tech further encrypts and provides du li key passwords, it means that even if other publishing houses in China reveal the truth, it will not affect Sony's own interests at all. Even Huaxia Hi-Tech can guarantee that this set of passwords and keys only For Sony's use, even Huaxia Hi-Tech's copy and the materials in the development process can be locked in the Swiss bank's vault under the witness of Sony, so that even Huaxia Hi-Tech itself has no information to crack it.

Hearing Jia Hongjian's reassurance, Sony's team was really moved, but they didn't make a decision directly on the spot, but chose to go back to the hotel to discuss with the head office before making a decision when Jia Hongjian sent them off. When a group of people went out, they all had smirks on their faces, why?Because although what Jia Hongjian said just now seemed to be undecipherable, in fact, he deliberately ignored one possibility, that is, what is a modified machine?That is, some hackers will buy the machine at the first time, and then rely on their solid foundation in both software and hardware to find out how to bypass the genuine detection system at the first time - such as jumping wires, or directly flying wires, etc. Soldering work, directly stop the work of the original detection chip, so that the machine will naturally not verify whether it is genuine when reading the disc

On the other hand, hackers with high technology will create "direct reading chips" by themselves, that is, to omit the action of flying wires and put a program in the chip as the owner of the game machine. After the machine is disassembled and the chip is soldered to the corresponding position on the main board of the game console, the order in which the machine reads is changed. It may be that the system is fixed. It will first check the verification code attached to the beginning and end of each game disc, and reject it if it fails. All the information after reading, but this direct-reading chip can directly "invalidate" the verification chip like a flying wire-directly use the program to make them sleep. In this way, as long as the game content can be extracted from the dump in the genuine game, Press the disk into a disk, then you can read it directly in the genuine machine. This is basically the invention of the magic chip that began to appear on the market three or four years after the ps1 generation was released. It really made some European and American magic hackers big money

What is the message that Jia Hongjian is worried about and hiding?This is the direct-reading chip. After all, he is not Ni Guangnan, not Wang Jizhi, and he made this chip himself. He doesn’t know if the machine can read ordinary discs like ordinary VCD machines without this chip—the theory This should be the case, because their cvd machines must be compatible with vcd, so they must do so. But if it is installed on a ps machine, will the game console be able to read it out stupidly after the direct reading chip paralyzes the prov chip? A normal game disc without any authentication information or codes?If it is possible, to be honest, it would be a waste for Sony to spend money on this chip, so how could Jia Hongjian tell others the whole truth?He, Jia Hongjian, has always told the truth, but most of the time he never tells the whole truth

After sending those people away, Jia Hongjian told his parents and went directly to Xiaomi Technology to talk to Ni Guangnan and Wang Jizhi about this issue. At this time, Nobuyuki Idei and Ken Kutaragi were talking to the president of Japan At this time when the company held a conference call, it was Kutaragi Ken's turn to report back: "As for the anti-counterfeiting mode developed by our company, we adopted an original idea, which is to record an anti-counterfeiting code in the mouth core master disc of the game pressure plate. Each disc pressed in this way will have this kind of anti-counterfeiting code. After this kind of anti-counterfeiting code is read and verified by the chip, the machine will continue to read the game content. With the original design, it is indeed possible to use a random genuine disc to pass the anti-counterfeiting verification, and then forcefully open the disc compartment at this time, causing the system to be interrupted, and then insert the disc, making the machine mistakenly think that the inserted disc is the same as the previous genuine disc It's a disc, and then read the content directly..."

After hearing Ken Kutaragi’s frankness, a group of old men at the Sony headquarters were silent. They originally had a lot of confidence in this PS project, but now they are about to face the sale, and the result is this kind of design. Isn't this a mistake that makes people anxious?After a long time, someone from the old man asked: "Then the method of this Chinese company can be effective? Can it be completely avoided?"

"It is theoretically so, because they not only add verification chips to the machine, but also use the principle of military ciphers, that is, when suppressing genuine discs, they directly encode and compile the digital information in the discs. Even in order to achieve excellent error correction and prevention capabilities, they also designed to break up all the information and evenly distribute it in every corner of the disc according to certain rules. In this way, if the decoding chip is not used for restoration, no one will lose the information. There is no way to play a normal game, because all the required data in the whole process of the game is scattered, and there is no way for devices without chips to read such scattered data. Therefore, in theory, such a design does not even need to be used. Add any verification code into the game disc, because all the information of the game itself has become a huge verification code. Even, we don’t have to carefully save the master disc of the disc in the future... because the chip has its own unique information, which is based on The whole encoding and decoding rules are used to decode, not only the unique information can be read and authenticated, so even if we use different master discs for each production, as long as they are encrypted with their technology, they will definitely be able to read them.”

"Is that so? Theoretically, we can also use this technology on our music CDs? Well... no, if the product has it, although the released discs can be read, the old machine can't read it. ...Or can we develop a CD player that uses encrypted discs? It is different from the MD player that can be read and written that was released two years ago?" Suddenly, the old men in the Sony headquarters started a strange discussion

It turned out that in 82, Sony had already started to make the CD Walkman. After making this thing for ten years, and after it became popular all over the world, they started to make something similar to a magnetic tape—minidisk, which is called md for short. This kind of md disc is very small, and it is loaded in a small completely sealed plastic box. Even when it is placed in the md player for reading, the plastic box is not opened at all. Sony carefully designed this md. Although it has It has a magical erase and write function, but the strange thing is that this thing is not very popular in the world. The main reason is the high price. At the same time, because of the recording, the song recording can only be transcribed by CD. In this case If so, why not just use the CD player to listen to the music?We must know that not only Sony itself, but also Panasonic and other manufacturers are making CD players in this era.

Since the ps host can use Huaxia Hi-Tech’s prov or even the evolution version of prov for exclusive use, why not get a CD with an 8cm size, and then Sony will make a full music compression mode, so that the small 8cm CD can be completely Can accommodate the next album, and then use Huaxia Hi-Tech's technology so that even CDs are impossible?And because of Sony's own unique music compression mode, Sony can cooperate with any record company in the world at that time, and share with the other party the specially produced and reprinted 8cm discs, so that they can fry leftovers and make money again. It is very in line with Sony's mode of closing the market and only doing its own thing

"Ask them what price they want, even if it is hundreds of millions of dollars to buy out all the technologies, we can agree." Soon, after some discussion among the old men at Sony headquarters, such a shocking order reached the ears of Nobuyuki Idei and Ken Kutaragi What?How about hundreds of millions of dollars?So what if Huaxia Hi-Tech wants to take a commission?What is the commission for each disc? "No, we must buy it out. It is impossible to take the least amount. Our bottom line is to buy out the exclusive code that was given to us in one go, and we will never give it a share." Sony's old men know the truth of business very well, and they are not going to tell Jia What is Hung-chien going to use the codecs after Sony bought them? Otherwise, if they take a commission everywhere, wouldn’t it be that the games will be paid to Huaxia Hi-Tech, and then the small CD market will also be given money in the future?It is absolutely impossible to lower the price if the price can be lowered. It is best to buy it out with a lump sum of money, so that all the extra money in the future will be Sony's

On the other side, Ni Guangnan and Wang Jizhi, after thinking about the question raised by Jia Hongjian for a long time, said: "The specific thing depends on how their machine is designed. If it is designed by us, then we two old men It can be completely designed so that the whole machine will not work if the decoding chip does not work. Put this program in the motherboard as the core program... Hey, but if someone has the same experience as the two of us, he can also program it by himself. The chip, as Mr. Jia said, is directly soldered to the motherboard, skipping the most core inspection, and it becomes a situation where birds occupy the dove's nest... It's not easy, Mr. Jia, to be honest, if the two of us come Come on, get a chip on that ps to skip our decoding chip, and then put that pure disk without any encoding into it to read, it should really be able to read and play..."

At this time, Jia Hongjian nodded. Although he knew this, he was not going to tell Sonny—he would not gain any extra benefits if he told Sonny. A good product cannot be perfected at one time. It has to be divided into several times to make small steps, so that you can keep making money from the pockets of big players, right?

This is sometimes the case in shopping malls, Sony is going to lower the price without telling Jia Hongjian, and Jia Hongjian is also thinking about raising the price more without telling Sony...to be continued)
