To talk about the mobile phone circle in the past two years, I feel that there is only one word: volume.
Roll screen, roll fast charge, roll image...
However, I found that there is one thing that people are relatively less concerned about, and that is the security of mobile phones.
Starting from MIUI 12, major mobile phone manufacturers have paid attention to the issue of system privacy.
Things like blocking bad information and hiding user privacy are basically standard features of android phones at present.
On the other hand, in terms of hardware, as a mobile platform for mobile phone brains, it has also made a lot of efforts in information security.
Today, let's talk about the things that make mobile phones safe.
The highest priority security feature
In fact, a long time ago, chip manufacturers began to work on security.
Like the 2015 Snapdragon 810, it was the first to add a SafeSwitch feature that has a higher startup priority than the operating system.
After the user loses the phone, he can use this feature to remotely lock the phone and clean the data.
In the past, the operation of stealing into the mobile phone and brushing the machine to crack has become history after this generation of mobile platforms.
The new generation of Snapdragon 8, which has evolved to today, not only continues the security features that have always existed, but also enables a new mobile security architecture.
I don't think it's too much to say that it's "reborn.".
According to the official account, the new generation of Snapdragon 8 contains more than 50 chipsets, all built on a security foundation.
Even at the launch of the Snapdragon 8, the first thing to talk about after the opening speech was the security features, which were higher in priority than the images, games and other characteristics that mobile phone manufacturers were rolling.
Of course, the security features still have to be implemented on the terminal device, let's talk about it.
Protect user safety from the "core"
The Hypervisor Deep Protection layer introduced by the previous generation of Snapdragon 888 enables effective data protection and isolation on the same endpoint, between different applications and multiple operating systems in a whole new way.
This technology is open sourced on the new generation of Snapdragon 8 for mobile phone manufacturers.
This also means that mobile phone manufacturers can "magically modify" this technology and add their own unique functions.
Take the recently released Honor Magic4 series, for example.
Based on Trustzone and Hypervisor virtualization mechanism, Honor has created a dual TEE system of "Qualcomm Q.TEE" + "Honor H.TEE".
This system is independent of the Android system and adheres to the concept of from the inside to the outside, soft and hard collaboration, and from the end to the cloud.
It's the equivalent of an assistant that helps you supervise the security of your phone.
Thanks to the dual TEE system, the Honor Magic4 series can ensure the safety of users in various high-risk scenarios.
Like mobile phone lock screen password, fingerprint/facial recognition unlock, encryption key, mobile payment, etc., can be protected from hacking under the dual TEE system.
In addition, the ultrasonic fingerprint carried by the overseas version of the Honor Magic4 series also adopts Qualcomm's solution.
This wave of security protection from the inside out is in place.
Under the open source Hypervisor, the new generation of Snapdragon 8 also adds a layer of trust management engine.
Under the action of this protective shield, mobile phones can better protect sensitive data and hardware root of trust for applications.
Even if there is a sudden information risk, Snapdragon 8 can change the local strategy through the cloud and react at the first time.
The cooperation of mobile phone manufacturers is also very important
Of course, chip manufacturers provide fundamental protection.
Implementing the corresponding technology at the system level, how to make users feel that they are "protected" is what mobile phone manufacturers have to do.
Fortunately, in the past two years, major mobile phone brands have gradually begun to pay attention to the problem of information security.
As mentioned at the beginning, a series of privacy protection features added by MIUI 12 have set off a wave of user information protection in the Android camp.
Subsequently, Android 12 also began to increase its efforts in privacy protection.
For example, when calling the camera and microphone, the corresponding reminder icon will be released in the top status bar, and the position blur function will be added.
Other vendors in the Android camp have also actively followed up, such as OPPO adding a mechanism to erase private information in ColorOS.
Whether it is a chip manufacturer in the upstream or a mobile phone manufacturer in the terminal, they are trying to awaken users' awareness of information security.
It is not an exaggeration to say that we have now entered a new era of information security.
The rudiments of the future information world have gradually been revealed
At present, information security, in practice, focuses more on privacy protection and preventing hacker intrusion, which seems to be nothing special.
But in fact, many new technologies have been added that can already give us a glimpse of the future.
In recent years, everyone has been talking about the Internet of Everything, but have you ever thought about what to do if all of our homes are connected to intelligent systems?
Qualcomm thought of it.
The trust management engine mentioned above not only adds security to the phone, but also makes the Snapdragon 8 the world's first mobile platform to comply with the Android Ready SE standard.
Many small partners may not be familiar with this standard, here is a brief talk.
The Android Ready SE standard is a technology alliance launched by Google in March 2021 to launch an open-source SE security interface and program that enables smart devices such as mobile phones to be used for digital keys, car keys, electronic passports, digital currencies, etc.
Under this standard, the Internet of Everything is fast enough and wide enough to achieve security.
In addition, the Snapdragon 8's secure processing unit also supports iSIM.
If the corresponding technology matures in the future, mobile phone manufacturers can even directly cut off the physical SIM card.
It not only makes room for the internal structure of the fuselage, but also makes it more convenient for users to use on a daily basis.
From the open source Hypervisor to the trust management engine, Qualcomm has established a solid information security shield from the chip level.
On this basis, mobile phone manufacturers can also better build a system security mechanism to protect user privacy from the inside out.
In addition, there are Android Ready SE standards and iSIM that focus on the Internet of Everything, although the corresponding new technologies have not yet been widely used, but it is clear that Qualcomm has laid a good foundation for the future.
Maybe after a while, these new technologies will shine in our lives.
