OSS implementation of the Trusted Computing Group's (TCG) TPM2
|
Software Stack (TSS). This stack consists of the following
|
layers from top to bottom:
|
|
* System API (SAPI) as described in the system level API and
|
TPM command transmission interface specification. This API
|
is a 1-to-1 mapping of the TPM2 commands documented in Part
|
3 of the TPM2 specification. Additionally there are
|
asynchronous versions of each command. These asynchronous
|
variants may be useful for integration into event-driven
|
programming environments. Both the synchronous and
|
asynchronous API are exposed through a single library:
|
libtss2-sys.
|
|
* TPM Command Transmission Interface (TCTI) that is described
|
in the same specification. This API provides a standard
|
interface to transmit / receive TPM command / response
|
buffers. It is expected that any number of libraries
|
implementing the TCTI API will be implemented as a way to
|
abstract various platform specific IPC mechanisms. Currently
|
this repository provides two TCTI implementations:
|
libtss2-tcti-device and libtss2-tcti-mssim. The prior should
|
be used for direct access to the TPM through the Linux
|
kernel driver. The later implements the protocol exposed by
|
the Microsoft software TPM2 simulator.

This option allows to enable Feature API (FAPI). Feature
|
API (FAPI) as described in the "TSS 2.0 Feature API
|
Specification" along with "TSS 2.0 JSON Data Types and
|
Policy Language Specification" This API is designed to be
|
very high-level API, intended to make programming with the
|
TPM as simple as possible. The API functions are exposed
|
through a single library: libtss2-fapi.
