Cr50 is an implementation of a TPM on Google's H1 security chip.
|
|
This uses the same open-source firmware as the Chromium OS EC.
|
|
While Cr50 has other features, its primary role is as the root of
|
|
trust for a device, It operates like a TPM and can be used with
|
|
verified boot. Cr50 is used on recent Chromebooks (since 2017).
