OSS implementation of the TCG TPM2 Software Stack (TSS2). 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.
