SoK: A Systematic Review of TEE Usage for Developing Trusted Applications
Trusted Execution Environments (TEEs) are a feature of modern central
processing units (CPUs) that aim to provide a high assurance, isolated
environment in which to run workloads that demand both confidentiality and
integrity. Hardware and software components in the CPU isolate workloads,
commonly referred to as Trusted Applications (TAs), from the main operating
system (OS). This article aims to analyse the TEE ecosystem, determine its
usability, and suggest improvements where necessary to make adoption easier. To
better understand TEE usage, we gathered academic and practical examples from a
total of 223 references. We summarise the literature and provide a publication
timeline, along with insights into the evolution of TEE research and
deployment. We categorise TAs into major groups and analyse the tools available
to developers. Lastly, we evaluate trusted container projects, test
performance, and identify the requirements for migrating applications inside
them.Comment: In The 18th International Conference on Availability, Reliability and
