With Ling Liang, who has good skills, Sun Cheng was finally liberated, and while using the Tianyan desktop computer installed in the activity room to try to extract the Symbian 3 system used by the N8, he moved out his notebook and studied the ios used by the iPhone4 with great interest. Pen "Fun" Pavilion www.biquge.info

Tianyan did not disappoint him, and more than an hour later, he got the latest version of the Android 2.2 operating system.

By the way, with the help of the information obtained in the online encyclopedia, Sun Cheng studied it carefully.

I don't know if I don't study, and I'm shocked when I research.

To say that the market share of today's mobile operating system, the Symbian series is really the first, although it has been showing a sharp downward trend for two years, but the Symbian system still has a global share of 47.81% in the first half of the year, ranking the king of mobile operating systems.

In comparison, Android, which has been open source for more than two years, has a market share of only 22.4% and iOS is only 9.71%, which together only exceeds half of Symbian's market share.

In terms of market share alone, the gap between the three operating systems that are the best performing today is actually obvious.

However, market share is not always entirely accurate.

For example, right now.

Because as we all know, the Symbian system is not only Symbian 3, but also includes several different series such as S40, S60, S80, S90 and so on.

"Interestingly, the Saipan 3 system, which was only released in the second half of this year, now has a market share of only 11.7%?"

This is a very embarrassing data, and Sun Cheng naturally understands this.

Although Google's Android operating system has been released to version 2.2 so far, but that's just a different version, people are concentrating on constantly improving the operating system, at least from Sun Cheng's operating experience, this system is already very good, although there are still a lot of things that need to be improved.

As for iOS, he quickly gave up on the idea of spending months hacking it on his own.

Although the Linux series of operating systems he is good at are the same as ios, all of which are Unix-like systems.

But Apple's engineers obviously set up a relatively complete defense system for it very conscientiously, so that Sun Cheng couldn't find a place to start for a while, which undoubtedly increased the difficulty of cracking.

But fortunately, he found on the Internet that there are special studios abroad, and they are happy to crack the iOS system and open the jailbreak system to the outside world.

Calculate the time, iphone4 has been on the market for a few months, and he plans to go to the [computer enthusiast forum] to see if he can find it after returning in the evening, and if not, he will go to the Apple community abroad.

It's also a Unix-like system, and the engineers in Symbian are less conscientious.

Although this Symbian 3 system is more suitable for smartphones than Saipan's S60 series, and the more hardware optimization than previous works also shows Symbian's sincerity, the shortcomings are still obvious.

The UI aesthetics and optimization are not mentioned as serious deficiencies as Android and iOS, and the hardware fragmentation of Symbian 3 is still serious.

To make matters worse, Nokia's exclusivity after the acquisition of Symbian resulted in a pitiful amount of software available for Symbian 3.

Although for some good programmers, Android software can be ported to Symbian 3 in a modified way, but such people are only a small number after all, and there are only a handful of studios and companies willing to port software for Symbian.

Worst of all, Symbian's engineers made a big fuss about safety.

The Unix system was developed with security in mind, which makes it a favorite infrastructure for major companies, but that doesn't mean it doesn't have security issues, in fact, Unix has a serious and insidious SSH vulnerability.

SHH is an important security tool in Unix systems, and many companies can easily ignore it and think that it can't be a problem.

As a result, a vulnerability about SHH still exists in all major Unix systems, including linux and Kirin 7.0, and Symbian 3 is naturally unavoidable, and even Android 2.2 is not aware of its existence.

By grasping this vulnerability, hackers can directly bypass the security mechanism of the system and gain control by adjusting the SHH configuration.

Linux-DDMS does not directly strip out the complete operating system like reading Android directly.

However, through the database comparison of Tianyan, after Sun Cheng mastered this vulnerability data, he was able to quickly write the attack code and directly bypass the security mechanism of Symbian 3 to obtain the highest permission.

Unfortunately, after learning about the excellence of the iOS system and the unlimited potential of Android, he has lost interest in this system that is seriously lacking in innovation.

I only used Linux-DDMS to find the communication records in my original mobile phone, and copied it directly to the newly bought N8, Sun Cheng immediately installed the phone card, ready to use it for the time being.

After a few moments, he threw his new phone, the N8, aside.

Sun Cheng's eyes lit up as he stared at the Android operating system that had just been copied to his computer, carefully skimming through each line of code, and constantly comparing it with the system that had formed a framework in his mind.

"You want to develop an operating system?"

Since he helped him get the Android system just now, Ling Liang didn't continue his work, and kept standing aside and watching him fiddle in front of his computer!

"Have this idea......"

He replied nonchalantly, never taking his eyes off the computer.

Ling Liang frowned, "Don't you know how troublesome it is to develop an operating system?" ”

After subconsciously estimating the time he would need, Sun Cheng quickly turned his face and looked at her with a smile: "It's just an idea, the development of a desktop-level operating system is quite difficult, but with Linux open source code, the mobile phone operating system is relatively easy!" ”

He really didn't mean to brag about this, in fact, with the domestic technical level, especially an operating system company like Fiberhome, it is really not difficult to develop a mobile operating system instead.

Sun Cheng used the 'Kirin 7.0 version' to roughly touch the foundation of this company, if that represents all their technical strength, then if Fiberhome is developed directly on the basis of the framework of the Kirin series, the beta version can be made in three months at most.

But the real problem is just beginning here.

The selection of default software, the detection and repair of vulnerabilities, and the most important thing is hardware optimization, which is far from a problem that can be solved in a month or two.

Without the deep pockets of Google and Apple, it is easy to convince hardware and software providers to follow their own standards, and the only way is to rely on technical hardware to build a powerful and domineering hardware adaptation system.

"It's good if you understand......"

As soon as Ling Liang spoke, before he could finish speaking, he heard a mobile phone ringing from the table.

Following the sound, the two quickly noticed that it was Sun Cheng's newly bought N8 mobile phone ringing.

"Answer the phone ......"

He nodded at Ling Liang, picked up his mobile phone and glanced at it, and found that it was an unfamiliar number from Ying Tianfu, and then groaned for a moment before pressing the answer button.

"Hey ......"

"Hey, may I ask if it is Your Excellency 'Knowledge is Truth'?"

A strange man's voice came from the other side of the phone, and Sun Cheng's eyes narrowed slightly.

There are not many people who know his screen name and his phone, and he can't help but wonder in his heart if he is dissatisfied with the fact that he has found several vulnerabilities on the [Computer Enthusiast Forum].

After a pause, he pondered his lines before replying, "It's me, may I ask ...... you?"

"Excuse me, I'm Fu Dong, CTO of Fiberhome. Because we have been leaving a message on the [Computer Enthusiast Forum] and can't get your reply, we had to contact the Tai Core Company, and the other party asked for your contact information, and wanted to talk to you......"

Although he was a little dissatisfied with Tai Hexin's private exposure of his phone, after learning who it was, Sun Cheng's eyes couldn't help but light up.

Just now he was still thinking about Beacon, and this domestic operating system developer has a lot of good cards in his hands.

Among them, he was most impressed by the source code and patents of the 'Kirin series' operating system developed based on Linux open source code, as well as its four office software.

Originally, Sun Cheng was still thinking about how to contact the beacon side, but now it's a good thing that one of his revelations directly blew up this big fish.

Seeing that Beacon was sent to the door by himself, how could he hold back, and replied very simply: "You are here for the other operating system vulnerabilities I have in my hands, right?" No problem, I'm going to school at the Imperial University, I must have told you about this point, if you want to talk to me, come to Anqing Mansion! ”

There was a slight silence on the other side of the phone for a moment, as if he didn't expect that he really had more system vulnerabilities in his hands.

However, after only a while, the man named Fu Dong answered: "...... In fact, we have already arrived at Anqing Mansion, but since the morning, we have made more than a dozen phone calls to Your Excellency, and Your Excellency's side has been turned off and cannot contact you. ”

"You've arrived!"

"Yes, it's currently in a café called 'Dior' near the Imperial University!"

"Okay, I know where it is, you wait for me, I'll go now!"

"Okay, looking forward to meeting you!"
