Trunks

Trunks is a daemon and library for interfacing with a Trusted Platform Module (TPM).

Be aware that trunks does not comply with the Trusted Computing Group (TCG) Software Stack (TSS) specification.

Components

trunksd

A daemon that centralizes access by other system daemons to a single shared TPM. Other daemons send D-Bus requests to trunksd with TPM commands, trunksd sends them through /dev/tpm0 (which can only be opened by a single process) and responds over D-Bus with the TPM response.

Trunksd also performs resource management for the TPM, loading and unloading objects transparently for the calling daemons.

libtrunks

The calling-daemon side shared library that provides a C++ API for serializing and deserializing various TPM commands and performing higher-level operations.

It is possible to use libtrunks independent of trunksd by providing a custom CommandTransceiver to perform communication directly with a TPM, but the default scenario is when libtrunks and trunksd are used together and communicate over a D-Bus based transceiver.

TPM Specification

See http://www.trustedcomputinggroup.org. This version of trunks is based on TPM 2.0 rev 00.99.

(*) Scraping for this version of trunks used Poppler's pdftotext utility v0.18.4.

Code Generation

generator/extract_structures.sh

Extracts structured information about types, constants, structures, and unions from generator/raw_structures_fixed.txt. The output of this script is intended to be parsed by generator.py.

generator/extract_commands.sh

Extracts structured information about commands from generator/raw_commands_fixed.txt. The output of this script is intended to be parsed by generator.py.

generator/generator.py

Generates C++ serialization and parsing code for TPM commands. Inputs must be formatted as by the extract_* scripts.
