GlobalPlatform and the TEE

The Trusted Execution Environment (TEE) is a secure area of the main processor of a connected device that ensures sensitive data is stored, processed and protected in an isolated and trusted environment. As such, it offers protection against software attacks, generated in the rich operating system (rich OS) environment.

The TEE’s ability to offer safe execution of authorized security software, known as ‘trusted applications’, enables it to provide end-to-end security by protecting the execution of authenticated code, confidentiality, authenticity, privacy, system integrity and data access rights.

GlobalPlatform Specifications
GlobalPlatform and its members recognize the need for standards to be developed in parallel with the evolution of a new ecosystem. This collaborative development of the TEE will provide greater certainty and lower the cost of progress for the industry by removing barriers caused by interoperability issues.

GlobalPlatform has already published a range of specifications which can be downloaded free of charge from the GlobalPlatform Device Specifications webpages.

GlobalPlatform Security Certification
The GlobalPlatform TEE Certification Scheme, managed by its TEE Security Evaluation Secretariat, enables vendors to confirm conformance of their TEE products to the organization’s TEE Protection Profile, through independent security evaluation.

The scheme aims to accelerate the deployment of certified TEE products and promote a globally interoperable connected device ecosystem. Additionally, it enables service providers to confidently and effectively manage risk, by ensuring that there is a consistent level of security across connected devices.
