Description

A specification for Dynamic Root of Trust for Measurement (DRTM) on the Arm architecture will be available Fall 2021. DRTM allows a system in a potentially unknown or untrusted state to boot an OS or hypervisor into a known and trusted state.

This topic will present an overview of DRTM on Arm to provide context, followed by discussion around several topics that have implications for the Linux kernel:

  • questions around the handoff from the dynamic launch to the Linux kernel
  • the problem of UEFI RT services in the context of DRTM and Linux
  • questions around supporting dynamic TPM localities on Arm systems
I agree to abide by the anti-harassment policy I agree
