How does Google’s Titan security chip work?

Powering trusted computing with advanced security at the hardware level.

➤Titan Is Google’s Custom-Built Security Chip:
Google’s Titan chip is a custom hardware component designed to protect sensitive data and secure device integrity from the ground up.
➤Built for Secure Boot Processes:
Titan ensures devices boot from a verified, trusted state every time by checking cryptographic signatures during startup, preventing tampering.
➤Used in Pixel Phones, Google Cloud, and Servers:
The Titan chip is used across Pixel devices (Titan M/M2), Google Cloud infrastructure, and data centers, ensuring a consistent security foundation.
➤Isolates Sensitive Information from Main Processors:
By handling security functions in a separate, isolated hardware environment, Titan protects critical operations like encryption and authentication.
➤Stores Cryptographic Keys Securely:
Titan chips are designed to generate, store, and manage encryption keys securely, keeping them safe from physical and software attacks.
➤Enables Two-Factor Authentication with Titan Security Keys:
Titan technology also powers Google’s Titan Security Keys, providing FIDO-compliant two-factor authentication to secure accounts against phishing.
➤Enhances On-Device Protection on Pixel Phones:
The Titan M and M2 chips used in Pixel devices protect sensitive operations such as lock screen passcodes, app data encryption, and secure transactions.
➤Defends Against Hardware-Level Threats:
Titan chips include physical tamper resistance and protection against side-channel attacks, making it hard for attackers to extract data even with direct access.
➤Supports Verified Firmware and Software Updates:
Firmware managed by the Titan chip is cryptographically signed and verified, ensuring only legitimate updates are installed on devices.
➤Part of Google’s Broader Security Ecosystem:
Titan is just one component of Google’s layered security strategy, working alongside software-based protections and AI to keep users and infrastructure safe.
