Titan M chip makes Google Pixel 3 more difficult to hack, protect bootloader

Titan M chip is a new component added by Google on Pixel 3, which is responsible for the security of the phone.

Titan M uses the inner Cortex-M3 core, directly attached to the operating system's security boot process, so it can save the latest secure version of Android so that hackers cannot downgrade Android to version less safe.

In addition, Titan M can even prevent bootloader unlocking so that malware cannot access the lowest software layer on the phone. In addition, this security chip also limits the number of login times and verification of the unlock code on the screen to prevent hackers from guessing the password.

Titan M is in a position independent of the SoC chip and uses an extra Flash memory to make it harder to hack. Applications using Google's StrongBox KeyStore platform are also using this chip to ensure payment authentication, preventing bad guys from stealing and making transactions. Titan M is also currently being tested by Google Pay to protect their interfaces.

The fact that Google focuses on developing its security chip is understandable as the privacy surrounding the technology industry is becoming more and more important and more urgent than ever. Most likely, this chip will become a central part of future Pixel devices.
