PC Client

Mission

The PC Client Work Group defines the capabilities and behavior of TCG technologies such as TPM and Opal in the context of a client endpoint computer (e.g. a laptop, desktop or tablet).

What the group does

The Work Group provides specifications, technical requirements, and guidance for the TPM and for platform OEMs and firmware vendors interacting with or integrating the TPM in their Platform. This includes defining PC Client specific requirements for specifications from other workgroups such as the Infrastructure Workgroup (Platform Certificate Profile Specification and Reference Integrity Manifest Information Model Specification) and other organizations such as the UEFI Forum (UEFI and ACPI specifications) or DMTF (SPDM specification).

Why it matters

PCs store sensitive information, cryptographic credentials, and personal or enterprise data, making them frequent targets for physical and remote attacks. The Work Group's specifications provide a hardware-backed foundation for protecting cryptographic keys, measuring platform integrity, supporting secure authentication, and enabling organizations to evaluate whether devices booted into an expected and trustworthy state. By defining consistent behavior across products, the Work Group also helps operating-system providers, PC manufacturers, and security-software developers build solutions that work reliably across devices from different vendors.

Who participates

TPM, System-on-Chip, Platform OEMs, Independent Firmware Vendors, and OS-present Driver vendors. Government and industry partners looking to drive better endpoint security. The Work Group coordinates with other TCG groups and external industry organizations whose technologies are used in PC platforms, including the TCG TPM, Infrastructure, Security Evaluation, and Storage Work Groups, as well as organizations responsible for technologies such as UEFI, ACPI, and NVM Express.
