The Mobile Platform Work Group (MPWG) is a TCG Technical work group that develops specifications and reference documents for mobile devices to support the wide variety of business models in consumer, enterprise, government, and academic environments. The Trusted Mobility Solutions Work Group (TMS) is a TCG Solutions work group that develops use cases, frameworks, and other reference documents to promote the adoption of TCG technologies within end-to-end solutions for mobile devices, telecom infrastructure, and enterprise networks. MPWG and TMS collaborate frequently to address the evolving challenges of the mobile device markets around the world.  The top priority of the MPWG and TMS WGs is to promote the adoption of sound trusted computing technologies in the mobile ecosystem.

The MPWG and TMS long-term strategy is to bring trusted computing technologies to mobile ecosystems in collaboration with other standards bodies.  The TCG has formal liaisons with Global Platform, the European Telecommunications Standards Institute (ETSI), and the Alliance for Telecommunications Industry Solutions (ATIS) and informal collaborations with numerous other standards organizations including 3GPP, GSMA, IETF, IEEE, and SAE.

MPWG has developed three core specifications to define fundamental TPM 2.0 Mobile capabilities:

• • • Trusted Platform Module (TPM) 2.0 Mobile Reference Architecture describes how to support a TPM, with protected capabilities and secure storage, on modern mobile device architectures (published 2014).
    • TPM 2.0 Mobile Command Response Buffer Interface provides a kernel interface to the TPM, suitable for all architectures (published 2014).
    • TPM 2.0 Mobile Common Profile provides a medium-scale subset of the TPM capabilities for mobile phones and other mobile devices (published 2015).

TMS has developed the following reference documents to provide implementation guidance for mobile devices and mobile ecosystems:

• • • TMS Use Cases v2 – Enterprise, Financial, & NFV (published 2018) is an evolution of TMS Use Cases v1 – Bring Your Own Device (BYOD) (published 2013) that expands the scope and provides guidance for applying TCG technologies to a broad range of mobile devices and mobile ecosystems.

The MPWG and TMS WG have also developed reference documents that provide guidance on how to implement trusted mobile platforms and tackle current and future critical security issues using TCG technologies, as well as technologies of other standards’ organizations:

• • • TCG Multiple Stakeholder Model describes how multiple stakeholders can coexist safely on mobile platform (published 2016).
    • TCG TPM 2.0 Mobile Specification Implementation Guidance is a one-stop reference for mobile platform designers, developers, and implementers to get started implementing the TPM 2.0 Mobile specifications (published 2018).
    • TCG Runtime Integrity Preservation for Mobile Devices addresses the challenge of platform integrity by recommending best practices and mechanisms to preserve the critical portions of the runtime state of mobile devices (published 2019).
