GlobalPlatform, the standard for secure digital services and devices, has published four technical documents to bring the benefits of the Trusted Execution Environment (TEE) to a wider range of IoT devices, including automotive and other consumer and industrial markets.
Now, GlobalPlatform provides further trusted foundations enabling stakeholders to trust the device and user management of their IoT devices, and the digital services running on them.
The specifications follow significant growth in the adoption of TEE-enabled processors, with the organization reporting a 25 percent increase in the number being shipped quarterly, year-on-year, in 2018.
“The TEE is well established in devices like smartphones and set-top boxes, highlighting its value to the IoT and automotive worlds,” explains GlobalPlatform’s Technical Director, Gil Bernabeu. “To support the IoT, we have continued our investment in trust and aligned with a wider range of global, regional and sector-specific requirements. With this work, we are enabling more collaborative and open ecosystems where digital services and devices can be trusted.”
Greater flexibility and trust for the IoT and consumer devices
With these updates GlobalPlatform has standardized trusted application (TA) deployment and management, optimized for IoT devices, providing greater technical and business opportunities for device manufacturers and service providers.
Trusted user interfaces (TUIs) and biometric support have been expanded to enable additional use cases and the biometric systems can now be certified, meaning it is possible to trust that the authentication has been performed in a secure environment.
The documents are:
GlobalPlatform Technology TEE Internal Core API Specification v1.2 – defines a set of APIs for the development of TAs running inside a TEE and adds new features to the TEE to support the latest platform and market requirements.
GlobalPlatform Technology TEE Management Framework (TMF): Open Trust Protocol (OTrP) Profile v1.0 – adds a TMF-OTrP profile to support multiple kinds of TEE management, increasing flexibility and streamlining TA development.
GlobalPlatform Technology TEE System Architecture v1.2 – brings key architectural and conceptual updates and clarifications into one place, enabling third parties to gain a quick overview of the possibilities when using a TEE.
