Google has detailed how its custom Titan security chip will prevent cyberattacks that use firmware-based attacks. As Google explained when it unveiled its tiny Titan chip, it would use it to give each server in its cloud its own identity. Now, it’s provided a more detailed rundown of what that means and how Titan will serve as a “hardware root of trust” to ensure each machine’s firmware is safe to load and provide other cryptographic functions in its data center.
