After Apple released the M1 chip version of the MacBook Pro last year, its excellent performance and battery life made it a hot topic of the year, and related discussions were endless.
Among them, in addition to the excellent performance of the M1 itself, performance and battery life are more easily perceived by users. In fact, the M1 chip, as an Apple self-developed chip under the ARM architecture, also allows Macs to be obtained in some places that are not easy to perceive, such as some security experiences. Updated.
In the Apple Security Platform webpage , which was updated in early February this year, the M1 chip is one of the highlights. Starting with the iPhone, Apple has paid great attention to the safety of its products. The self-developed A-series chips also allow it to integrate software and hardware to protect equipment.
Users familiar with Apple products should have the impression that most Apple devices suggest that users set a device unlock password, which is obviously to protect user data and privacy.
But this also caused a problem, that is, the password is too long and users are unwilling to enter it, and some users even do not set the password directly. For a device that contains personal privacy and even money data, there is no personalized protection such as a password. It is not safe.
How can users use Apple devices conveniently and safely?
In the end, Apple's answer is biometrics. The specific technology is Touch ID fingerprint recognition and Face ID facial recognition that we often use today. Today, a large number of Apple devices are equipped with these two technologies.
Mac is no exception. Apple’s newly released security website details how Touch ID completes recognition and how to ensure that relevant data will not be reversely cracked.
Take fingerprint recognition on the Mac as an example. When the user presses the fingerprint, the relevant data will be transmitted to the special security compartment of the M1 chip. An Apple spokesperson also gave a vivid analogy of this, saying that the security compartment is on the chip. The positioning in is like a vault in a bank, with a higher level of security.
These data will be stored locally, and are not specific fingerprint images, but numbers composed of encryption technology, ensuring that other people cannot obtain actual personal fingerprint images from the stored data through reverse engineering.
For the data in the Mac, it will also be supported by the sub-unit in the M1 chip to protect the data stored locally in the Mac in an encrypted form.
There are also corresponding protections for macOS systems, such as the secure boot function. Once this function is turned on, under the control of the M1 chip, it is ensured that the Mac is booted from a legal and certified system to prevent malicious software from tampering with the system.
Speaking of this, some Apple users may be a little curious. In the past, these functions were not all handled by the T2 chip in the Mac. There are differences between the M1 chip and the T2 in terms of security protection.
It is understood that T2 is an independent chip. It used to be separate from Intel processors. MacOS does not run on the T2 chip. It cannot achieve software and hardware cooperation. However, the M1 chip is different. It is a sub-unit responsible for related safety control. All are integrated into the M1 chip.
▲The M1 chip contains many sub-units, such as CPU and GPU
From the support of the hardware bottom layer, it is obvious that the Mac equipped with the M1 chip performs better and faster in the functions or technologies such as the security compartment, secure boot, and data encryption protection just mentioned. The characteristics are imported into the self-developed chip, and the development of Mac security protection and personal privacy protection will be more perfect in the future.
Of course, they are all chips based on the ARM architecture, which will also promote the safety experience of Macs equipped with M1 chips to be consistent with iPhone and iPad in terms of security experience. And Apple's product security protection and user privacy protection are not only for hardware and encrypted data protection, but also extended to a series of services formed by Apple such as the operating system and third-party apps, and even iMessage.
Note: The new version of the security platform webpage has not yet been fully launched in the Apple region
