Google explains how Pixel 3's stunning Titan M chip secures the phone – BGR



Google today announced some of the first details supporting its claim that the Pixel 3 was its "safest phone", linking up with the details it gave flagship during the recently performed New York Pixel 3 event Phones are the first to receive the company's Titan M security chip.

This chip, Google said today in a blog post, is a security chip developed specifically for the Pixel 3 Xiaowen Xin explains in the post that Google has the best features of the Titan chip operating in the company's Google Cloud data centers used for mobile devices. As the CNET report states, the Titan M chip is also a dedicated Google chip – not part of the Qualcomm Snapdragon 845 processor, which already has a number of security features.

Here are a few ways that Titan M protects your phone, "Xin explains in the post." To protect Android from outside manipulation, we've integrated Titan M into our secure boot process, "Verified Boot."

"Titan M helps the bootloader ̵

1; the program to validate and load Android when the phone is turned on using the correct version of Android." In particular, Titan M saves the last known secure Android version and prevents " Poor Actors "Moving your device back to an older, potentially vulnerable version of Android behind your back Titan M also prevents attackers on Android from unlocking the bootloader."

The Titan M is also used by the Pixel 3, to check the lock screen passcode and limit the number of login attempts. Once the passcode is verified, the Titan M allows decryption – and the secure flash and fully independent calculation of Titan M, Xin's Posts adds, also makes it more difficult for an attacker to manipulate the process to learn what he is decrypting Needed Data

Another important point: The Pixel 3 also protects the chip to protect third-party apps and protect sensitive transactions. Xin explains that apps running Android 9 can now take advantage of StrongBox KeyStore APIs to generate and store private keys in Titan M. "The Google Pay Team," states the message They are actively testing these new APIs to secure transactions. " For apps that rely on user interaction to validate a transaction, Titan M now enables the Android 9 Protected Confirmation – the first device to be delivered with this protection, according to Google.

Finally, Google has Titan M" Insider Resistance "built in, which means that the firmware can not be updated if you did not enter your passcode and poor performers failed to bypass the lock screen.

We certainly were fascinated by the first word about the chip and even went so far as to see him perhaps even more exciting than the camera processor and perhaps even miss a rival of any kind on computer devices. "With the Pixel 3," Xin's Post concludes today over the phone that will enter tomorrow US is trading, "we have increased our investment in security and industry-leading hardware features in the ger t integrated so you can be sure that security and privacy are well protected.
