Vehicle Services

Overview

The Trusted Computing Group (TCG) Vehicle Services Work Group (VSWG) promotes the adoption and evolution of TCG technologies within automotive ecosystems. The group provides guidance, specifications, reference architectures, and industry expertise to establish trusted computing foundations for vehicle cybersecurity, device identity, platform integrity, and emerging mobility services.

What the group does

VSWG evaluates, adapts, and promotes TCG technologies for automotive platforms, connected vehicle services, and Software-Defined Vehicle (SDV) architectures. The group develops specifications, white papers, reference architectures, use cases, and implementation guidance that help automotive manufacturers, suppliers, and ecosystem partners deploy trusted security technologies throughout the vehicle lifecycle.

Current activities include the TVTA (Vehicle Trust Anchor) proof-of-concept project, EV charging security initiatives, automotive threat analysis, and collaboration with industry standards organizations to encourage adoption of trusted computing technologies across future vehicle and mobility ecosystems.

Why it matters

Modern vehicles are increasingly connected, and software-defined platforms depend on trusted identities, secure communications, software integrity, and resilient supply chains. VSWG helps the industry establish trusted security foundations that strengthen cybersecurity, support regulatory and safety objectives, protect critical vehicle functions, and enable secure interactions between vehicles, infrastructure, cloud services, and mobility ecosystems.

Through initiatives such as the TVTA proof of concept and EV charging security work, VSWG demonstrates practical approaches for deploying trusted computing technologies in next-generation automotive platforms.

Who participates

VSWG brings together automotive OEMs, semiconductor manufacturers, cybersecurity experts, research organizations, and trusted computing specialists. Active participants include organizations such as Toyota, Fraunhofer, STMicroelectronics, Infineon, NSING, SealSQ, and other TCG member companies.

The group also collaborates with automotive standards organizations, industry alliances, and ecosystem stakeholders to promote interoperability and adoption of trusted computing technologies throughout the automotive value chain.
