To establish a precise definition and conceptual foundation for Trusted Execution Environments (TEEs) while resolving ambiguities with related computing concepts.
Characterized the core properties, trust models, and formal verification requirements defining TEE architectures.
Surveyed and systematically evaluated existing academic and industrial ARM TrustZone-based implementations.
Analyzed published attack vectors and threat models targeting deployed TEE systems across diverse applications.
Formulated a rigorous architectural baseline distinguishing TEEs from alternative paradigms like secure execution environments.
Identified critical implementation vulnerabilities and recurring security weaknesses in operational ARM TrustZone deployments.
