The Mobile Platform Work Group (MPWG) is a TCG Technical WG that develops specifications and reference documents. The Trusted Mobility Solutions Work Group (TMS) is a TCG Solutions WG that develops use cases, frameworks, and other reference documents. MPWG and TMS collaborate frequently to address the evolving challenges of the mobile device markets around the world.
The Mobile Platform Work Group (MPWG) promotes the implementation of TCG technologies in mobile devices to support the wide variety of business models in consumer, enterprise, government, and academic environments. MPWG defines specifications and recommendations for trustworthy mobile devices that address the resource constraints of mobile devices (e.g., intermittent connectivity and limited battery life). MPWG collaborates closely with Global Platform and has co-developed recommended best practices for the use of Trusted Execution Environment (TEE) and other Global Platform technologies in trusted mobile devices.
The Trusted Mobility Solutions (TMS) Work Group promotes the adoption of TCG technologies within end-to-end solutions for mobile devices, telecom infrastructure, and enterprise networks. Mobile devices should include trustworthy device identity, strong authentication, device integrity, secure storage, and virtualization. In enterprise networks, mobile devices should also include policy-based access control, and application and data isolation mechanisms. TMS collaborates closely with Global Platform (secure computing), Mobey Forum (mobile banking), European Telecommunications Standards Institute (ETSI, network function virtualization and security), Open Mobile Alliance (OMA, device provisioning), and other standards bodies.
Figure 1 – Graphic: Example Architecture of a Protected Environment running a TPM Mobile
TPM 2.0 Mobile Reference Architecture: This specification defines an architecture for the implementation of a TPM 2.0 executing within a Protected Environment (in mobile platforms). It includes informative examples of several implementation approaches.
TPM 2.0 Mobile Common Profile: This specification defines a profile of the TPM 2.0 Library Specification applicable to all mobile devices that conform to the TPM 2.0 Mobile Reference Architecture that is optimized for ease-of-implementation in feature phones, basic phones, eBook readers, and other similar constrained mobile devices.
TPM 2.0 Mobile Command Response Buffer Interface: This specification defines an interface between a TPM and software and is intended to work with a large number of hardware implementation options, including a discrete TPM on a peripheral bus or firmware TPM in a Protected Environment as defined in the Mobile Reference Architecture. The Mobile CRB Interface can be implemented on any platform architecture, including PC Client systems.
TMS Use Cases – Bring Your Own Device (BYOD): This reference document considers a broad range of scenarios where TCG technologies can be applied in mobile device ecosystems.
The Mobile Platform and TMS work groups develop standards, implementation guidelines, use cases, and solutions that integrate core TCG technologies (including TPM, TNC, and SED) into mobile devices, telecom infrastructure, and enterprise networks to enable support for trusted computing in critical mobile applications such as mobile banking, health care, and distributed computing. MPWG and TMS actively reach out and collaborate with external standards bodies to include explicit requirements for TCG technologies in international security and mobile standards. MPWG has been active since TCG was founded and TMS has been active for over five years.
