The Trusted Execution Environment: Delivering Enhanced Security at a Lower Cost to the Mobile Market

This document is intended as a high-level introduction to the Trusted Execution Environment, and this paper is a wholesale revision of a 2011 whitepaper published on the same topic. While it contains several use cases in an effort to introduce the TEE to stakeholders across the industry, it is not intended to be a technical document. GlobalPlatform envisions publishing two complementary documents in 2015 aimed at addressing technical topics–a Technical Whitepaper to introduce the architecture and components/building blocks of a TEE, and a Device Assurance Whitepaper to discuss the TEE Compliance and Certification programs.
