Coquettish Rebirth

Here, Jia Hongjian received preferential treatment from Cheng Yu. Cheng Yu sent Jia Hongjian back to the company first, and then returned to the municipal government in a circle.After Jia Hongjian returned to the company, he first held a small meeting, and arranged a little bit about what he had said to Cheng Yu before, and asked Xiaomi Technology to study how to modify the printer or what kind of printer to use to print photos. , and whether consumables such as photographic paper can be localized.

After resting for two days, Jia Hongjian participated in a meeting on the acceptance results of the security system made under the leadership of Xiaomi Technology held by the National 863 Program Review and Acceptance Committee.At this meeting, of course, before the meeting, Jia Hongjian also briefly tried out this system that has been in development for almost four years!For the trial, he sneaked to Xiaomi Technology, or the building where Xiaomi Technology used to be, and then ran on a notebook of Ni Guangnan.

This so-called security system is a bit similar to wnows. It is also a visual operating system, and it also has a bottom bar and a start button.However, the names of some specific functions and charts are different. For example, "My Computer" is not called "My Computer", but a name like "My Disk", while "Recycle Bin" is changed to "My Computer". It became a name like "trash can".

Of course, the whole system looks like wn95, but it's not.This system itself is modified from the core kernel of open source systems such as unx and lnux.Specifically, this system is the 10 codes of version 17 in the lnux system.Such an operating system has been formed by increasing to almost 50 codes.For such an operating system, the communication protocol itself is encrypted, and the encryption method was developed by the military.As for this operating system, by using the kernel of lnux, an open-source operating system has been changed into a closed-source one, that is to say, the operator can no longer modify the system by himself from time to time, which is also out of confidentiality considerations.

Naturally, I thought that with this system, the entire Chinese military industry would not have to worry about confidentiality, and it would be able to open the connection between the internal network and the external network.This is obviously impossible.Really want to keep it private.It still needs to be physically isolated from the internal and external networks, and it still needs to start with personnel confidentiality education, and such an operating system just gives a chance not to be infected by the American "super factory" virus.Or the chance of not being easily hacked!

Why do you say that?Because the American "super factory" was able to attack Iran's nuclear facilities.The main reason is that the Iranian facility itself uses the wnows operating platform.So it can be attacked by this virus based on the wnows-based platform!And what about the core platform of lnux?At least for Jia Hongjian in 2012, he had never heard any reports of lnux or unx being attacked by viruses, at least there were no reports that could be verified!

Of course.From a certain point of view, it can be considered that because lnux is used by fewer people, the overall ratio is much smaller than that of Microsoft, and maybe even less than Apple's mos, so who would bother to develop a virus for lnux?Has anyone heard of a virus targeting the Apple system?But in fact, this lnux and unx anti-virus is much better than wnows!Except that few people use them, their core does not have as many loopholes as wnows, and ordinary users will not be in the root directory all day during operation. This is his way of working, so lnux and unx systems are also very Not suitable for viral transmission!For example, President Obama of the United States will force all government agencies in the United States to switch to the lnux system, which is safe and will not spend so much money on genuine software.

For example, the software made by many military departments led by Huaxia Hi-Tech basically retains the kernel of a lnux system, so that viruses are not easy to cause harm - because it still retains the need to enter passwords to control access rights Therefore, it is very troublesome for the virus to modify the system, and in this way, the virus can only reproduce itself and consume memory in a small range, which is not harmful to the entire system!

Moreover, on any installed software, Jia Hongjian's Huaxia Hi-Tech has modified this system to the point that each installed software needs to provide a standard m5-like verification code to prevent counterfeiting!At the same time, the background will be connected to the Internet for identification with the internal server!In this way, if it is a modified software or a software with a virus inside, it is theoretically impossible to be installed successfully!And it's not too troublesome to do so-it's impossible to say that a police officer or an uncle of the People's Liberation Army will go out to perform tasks with a laptop equipped with this system, and they need to install software halfway, right?It's impossible to think about it!If you want to install it, you can install it before sending it out. If you want to add it, you can add it later. Isn't that all right? [

On the other hand, after Huaxia Hi-Tech gives the source code to the people in the military industry department, they will often let the experts of the "blue team" try to find the loopholes in the kernel and the entire system, and then the red team can find out the loopholes in the kernel and the entire system. By modifying the kernel to make up for the loopholes, this speed is much faster than wnows!At the same time, because this system is a deeply modified version of lnux, which is even very different from the version of lnux20, so even if Americans want to get a virus, unless they really get such a set of software and then understand the system kernel Yes, after understanding the working mode and its inner principle, it is possible to create viruses!And in this way, to some extent, doesn't it greatly reduce the possibility of being attacked?Isn't it much safer than using wnows?

Of course, if you want to talk about this matter, why not do a full set of dramas and create a completely independent platform?Why not get a kernel that's entirely our own?Why is it necessary to modify other people's lnux kernel?The reason is very simple - this is the first time for Xiaomi Technology to practice hands!This is entirely a chance for Jia Hongjian to practice his skills!It is impossible for us to say that we can create a completely autonomous system without any experience, right?How many teams in the world have this ability?So first get familiar with it by modifying other people's methods, then increase the code through various requirements, and finally become proficient, we can create independently!

Of course, the security system made by Huaxia Hi-Tech has passed the 863 inspection, there is no doubt about it.Although at the beginning, many leading cadres did not understand why this thing is the lnux kernel, not the wnows kernel, especially some leading cadres of the public security and police, but after using it, they saw a variety of viruses After the attack was effective, they realized how good this thing is!Plus, it saves money too!Jia Hongjian and the others used the project funding provided by the state to conduct research. After the research, it does not mean that it is the same as wnows95 or something, 600 yuan per disk, but about 10 yuan per disk. The cheapness of money sold to the state.In this way, the state is equivalent to "allocating funds" to Huaxia Hi-Tech as a reward, and it also gives Huaxia Hi-Tech interest in further efforts in this area in the future, and it can save a lot of money for genuine software at the same time!After all, it is impossible to say that the internal system of the Ministry of Public Security and the system of the army are installed with pirated Wnows system, right?Who knows what people have modified inside, installed a back door or not!

After participating in this meeting here, Jia Hongjian and his Huaxia Hi-Tech related working group received extremely high praise!For this, Jia Hongjian also gave a bonus of 5 yuan to himself as a reward. After all, people from the Military Industry Research Institute, Inspur Group, and the like also have various second-class and third-class merits within the army, while Huaxia Hi-Tech No!Of course, Jia Hongjian himself has also received high praise from the military, public security and central leaders!In the eyes of these leaders, Jia Hongjian and his Huaxia Hi-Tech are not state-owned enterprises better than state-owned enterprises!It is obviously a private enterprise, but it is very revolutionary, and it knows how to get closer to the central government!Look at how well this is done!This kind of private company, which has been honed by the market economy, is jointly developed by the military industry institute, which is beneficial to both parties.On the one hand, it can bring a lot of new work concepts to the people in the military industry, and at the same time, it can also reduce part of the research and development funds and personnel costs. It can be said that it really kills two birds with one stone!

At this time, Jia Hongjian felt that his foundation was not strong enough, otherwise he would have taken the opportunity to ask the country to give them Huaxia High-Tech a privilege, that is, to participate in the production of military weapons!That's right!In China in the 21st century, this right is open to private companies. Of course, it doesn’t mean that cats and dogs can get it. It has to go through countless layers of audits, and the company also has various troops stationed and various anti-leakage facilities. Measures, but build an armored vehicle for the country to purchase, that profit!Yes or no?Much more cost-effective than building a car!After all, this country is demanding performance, and doesn't care so much about cost!For Huaxia Hi-Tech, by participating in the manufacture of military weapons to test and develop their new technologies, and then practice in the military field with a high yield rate, and slowly pass the license and then transfer to the civilian market, how good it is!However, now Jia Hongjian's company can only make cheap cars, so he can only talk about this idea in a few years.

At this time, he boarded the plane and flew to Japan, ready to take a good look at the professional-level digital cameras and other things in Japan.Originally, Jia Hongjian wanted to bring Mr. Ni Guangnan to Japan, but in the end, because this old man had just participated in the work of the security system, he was restricted from going abroad for 5 years... No way, Jia Hongjian could only Said that I bought the equipment abroad, brought it back and asked the old man to disassemble it, how to program, how to design the program so that the foreign professional digital camera can shoot 60 times per second and so on... (to be continued...)
