PC Client Work group produces specifications and whitepapers to provide common functionality, interfaces, and a set of security and privacy requirements for PC Client platforms that use TCG components to establish their root of trust. This includes specifications addressing the requirements for PC Client specific TPM’s, PC Client specific platforms, the PC Client TPM interfaces and the interfaces between the different elements of the PC Client platform.
This Work group serves an advisory role by providing information to the TPM Work group and other TCG Work groups on possible architectural and design issues that may impact their work. This Work group also supports other platform Work groups at their request to specify additional TPM interfaces.
PC Client standards refine the definition of a TPM from the TPM Library specification based on the needs and common usage of PC Client platforms. These standards include the PC Client Specific Platform TPM Profile which defines the requirements for the TPM, the PC Client Specific Platform Firmware Profile which defines the platform firmware behavior in the context of a TPM enabled system, and several other specifications which provide interfaces and communication standards between OS present components and the platform firmware for the purpose of using and managing the TPM.
