PC Client
The PC Client Work Group provides common functionality, interfaces, and a minimum set of security and privacy requirements for PC client that use TCG components to establish their root of trust. 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's deliverables do not address any functionality, interface (except those interfaces between the OS and the pre-OS environment), security or privacy issues for the Operating System(s) that are hosted by the platform.
This document contains the registry of allocated vendor IDs.
PC Client Work Group PC Client Specific TPM Interface Specification (TIS)
The TCG architecture specifications define a TPM for use on any non-platform specific platform. However, due to the requirements to support Dynamic Locality features specific to the PC Client are necessary for the TPM. These PC Client features are defined in the section.
The Trusted Computing Group's architecture is a platform independent architecture to enhance trust on computing platforms. As such, the TCG Main Specification is general in specifying both hardware and software requirements. The goal of the TCG member companies is to ensure compatibility among implementations within each computing architecture. It is expected that companion implementation documents will be created for each architecture.
TCG Design, Implementation, and Usage Principles (Best Practices)
The intention of this document is to lay out the principles underlying the design of the TCG specifications.
TCG Physical Presence Interface Specification
The Physical Presence Interface utilizes the industry-standard Advanced Configuration and Power Interface (ACPI) to provide a communication mechanism between the OS and the BIOS, enabling the OS and the BIOS to cooperate to provide a simple and straightforward platform user experience for administering the TPM without sacrificing security.
PC Client Work Group Platform Reset Attack Mitigation Specification, Version 1.0
When a platform reboots or shuts down, the contents of volatile memory (RAM) are not immediately lost. Without an electric charge to maintain the data in memory, the data will begin to decay. During this period, there is a short timeframe during which an attacker can turn off or reboot the platform, and quickly turn it back on to boot into a program that dumps the contents of memory. Encryption keys and other secrets can be easily compromised through this method.
TCG Architecture Overview, Version 1.4
This Architectural Overview provides an introduction to TCG goals and architecture. It defines anticipated scenarios for use of TPM enabled platforms, compliance procedures and anticipated implications on manufacturing and support processes. Anyone looking for an overview of TCG specification and its implications should read this document.
TCG EFI Protocol Version 1.20, Revision 1.0
The purpose of this document is to define a standard interface to the TPM on an EFI platform. This standard interface is useful on any of the three example instantiations of an EFI platform shown in Figures 2-1, 2-2, and 2-3, as well as other instantiations.
TCG EFI Platform Specification Version 1.20, Revision 1.0
This document is about the processes that boot an EFI platform and boot an OS on that platform. Specifically, this specification contains the requirements for measuring boot events into TPM PCRs and adding boot event entries into the Event Log.
PC Client Work Group PC Specific Implementation Specification, Version 1.1
This document serves as implementation reference document for the 32-bit PC architecture.
