This is how your iPhone, MAC and iPad are protected

After Apple released the M1 chip version of MacBook Pro last year, its excellent performance and endurance made it a hot topic in that year, and there was an endless stream of related discussions.

In addition to the excellent performance of M1 itself, the performance and endurance are easy to be perceived by users. In fact, M1 chip, as Apple's self-developed chip under arm architecture, has also updated MAC in some places that are not easy to be perceived, such as security experience.


Updated in early February this yearApple security platform webpageM1 chip is one of the key contents. Since the iPhone, Apple has paid close attention to the safety of its products, and its self-developed A-Series chips also enable it to achieve the integration of software and hardware to protect devices.

Users who are familiar with Apple products should be impressed. Most Apple Devices suggest that users set the device unlock password, which is obviously to protect user data and privacy.

But this also causes a problem, that is, the password is too long, users are unwilling to enter it, and even some users do not set the password directly. For a device that contains personal privacy and even money data, it is certainly not safe without the personalized protection of password.


How to let users use Apple devices conveniently and safely?

Finally, the answer of apple is biometrics. The specific technologies are touch ID fingerprint recognition and face ID face recognition, which are often used today. Nowadays, a large number of Apple devices are equipped with these two technologies.

Mac is no exception. In Apple's newly released security website, it introduces in detail how touch ID can complete the identification and how to ensure that the relevant data will not be reverse cracked.

Take fingerprint identification on MAC as an example. When the user presses the fingerprint, the relevant data will be transmitted to the special security partition in M1 chip. An apple spokesman also gave a vivid analogy to this, saying that the location of the security partition in the chip is like a vault in a bank, with a higher security level.


These data will be stored locally, and it is not a specific fingerprint image, but a number composed of encryption technology, which ensures that other people can not obtain the actual personal fingerprint image from the stored data through reverse engineering.

For the data in MAC, it is also supported by the sub unit in M1 chip to protect the data stored in MAC in the form of encryption.

The Mac OS system also has corresponding protection, such as the safe start function. Once the function is turned on, under the control of M1 chip, it ensures that the MAC is started from a legal and authenticated system to prevent malicious software from tampering with the system.


At this point, some apple users may be a little curious. In the past, these functions were not all processed through the T2 chip in the Mac. There are differences between M1 chip and T2 chip in terms of security protection.

It is understood that T2 is an independent chip. In the past, it was separated from Intel processor, and MacOS did not run on T2 chip. It is impossible to combine software and hardware, but M1 chip is different. The sub units responsible for relevant security control are integrated into M1 chip.


The M1 chip contains many sub units, such as CPU and GPU

From the support of the underlying hardware, it is obvious that the Mac with M1 chip performs better and faster in the security partition, secure startup, data encryption protection and other functions or technologies just mentioned. With Apple's introduction of T2 features into its own chip, the development of MAC security protection and personal privacy protection will be more perfect.

Of course, these chips are all based on ARM architecture, which will promote the MAC equipped with M1 chip to a certain extent to be consistent with the iPhone and iPad in terms of security experience. Apple's product security protection and user privacy protection are not only aimed at hardware and encrypted data protection, but also extended to a series of Apple services such as operating system, third-party app, and even IMessage.

Note: Apple's national security platform has not been fully launched
