Trusted Execution Environments

Trusted execution environments (TEEs) protect sensitive code and data on computing platforms, even when the primary operating system is compromised. Once a technical curiosity, TEEs have rapidly become a key component in securing numerous systems from cloud servers to constrained devices. Today, TEEs have been deployed on billions of devices for protecting financial payments, personal files, copyrighted media content, and many others. Despite this, TEEs remain poorly understood due to their comp
