TPM Support

Introduction

This allows enumerating Trusted Platform Modules, also known as "TPM" devices, although it does not allow the user to update the firmware on them.

GUID Generation

These devices use custom GUIDs:

TPM\VEN_$(manufacturer)&DEV_$(type)
TPM\VEN_$(manufacturer)&MOD_$(vendor-string)
TPM\VEN_$(manufacturer)&DEV_$(type)_VER_$(family),
TPM\VEN_$(manufacturer)&MOD_$(vendor-string)_VER_$(family)

...where family is either 2.0 or 1.2

Example GUIDs from a real system containing a TPM from Intel:

  Guid:                 34801700-3a50-5b05-820c-fe14580e4c2d <- TPM\VEN_INTC&DEV_0000
  Guid:                 03f304f4-223e-54f4-b2c1-c3cf3b5817c6 <- TPM\VEN_INTC&DEV_0000&VER_2.0

Vendor ID Security

The device is not upgradable and thus requires no vendor ID set.

External interface access

This plugin uses the tpm2-tss library to access the TPM. It requires access to /sys/class/tpm.
