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:
libsapi.
* 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:
libtcti-device and libtcti-socket. 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.
