Titan M2™ supports Android Strongbox, which securely generates and stores keys used to protect your PINs and password, and works hand-in-hand with Google Tensor security core to protect user data keys while in use in the SoC. Titan M2 TM has been tested against the most rigorous standard for vulnerability assessment, AVA_VAN.5, by an independent, accredited evaluation lab. In this next generation chip, we moved to an in-house designed RISC-V processor, with extra speed and memory, and made it even more resilient to advanced attacks. With Pixel 6 and Pixel 6 Pro your security is enhanced by the new Titan M2 TM, our discrete security chip, fully designed and developed by Google. Trusty OS is the secure OS used both in TrustZone and the Google Tensor security core. Your secure hardware is only as good as your secure OS, and we are using Trusty, our open source trusted execution environment. For Pixel 6 and 6 Pro, the security core’s primary use cases include protecting user data keys at runtime, hardening secure boot, and interfacing with Titan M2 TM.

It's distinct from the application processor, not only logically, but physically, and consists of a dedicated CPU, ROM, one-time-programmable (OTP) memory, crypto engine, internal SRAM, and protected DRAM. The Google Tensor security core is a custom designed security subsystem dedicated to the preservation of user privacy. TrustZone is a key part of our security architecture for general secure processing, but the security improvements included in Google Tensor go beyond TrustZone. Google Tensor’s main processors are Arm-based and utilize TrustZone™ technology. Google has put user data protection and transparency at the forefront of hardware security with Google Tensor.

Multiple dedicated security teams have also worked to ensure that Pixel’s security is provable through transparency and external validation. These new Pixel smartphones take a layered security approach, with innovations spanning across the Google Tensor system on a chip (SoC) hardware to new Pixel-first features in the Android operating system, making it the first Pixel phone with Google security from the silicon all the way to the data center.

With Pixel 6 and Pixel 6 Pro, we’re launching our most secure Pixel phone yet, with 5 years of security updates and the most layers of hardware security. Posted by Dave Kleidermacher, Jesse Seed, Brandon Barbello, and Stephan Somogyi, Android, Pixel & Tensor security teams
