| 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. |
