TPM Software Stack (TSS)

The TPM Software Stack (TSS) is a software specification that provides a standard API for accessing the functions of the TPM. Application developers can use this software specification to develop inter-operable client applications for more tamper-resistant computing.

The purpose of the TSS Work Group is to provide a standard set of APIs for Application vendors who wish to make use of the TPM. The group works to produce a vendor neutral specification which will provide an abstraction of the hardware differences so that application vendors can write applications that will work regardless of the hardware, Operating System, or environment that is used. The TSS also aims to provide means for applications to talk to TPM’s either locally or remotely.
