Usman Ali, Hamza Omar, Chujiao Ma, Vaibhav Garg, Omar Khan

Hardware-based Root of Trust (HRT) is considered the gold standard for bootstrapping trust in secure computing. This paper analyzes HRT implementations across state-of-the-art TEEs and differentiates HRT implementation across two dimensions: 1) Security Properties & Threats and 2) Hardware Capabilities. Later, this work analyzes and compares 1) Intel SGX, 2) ARM TrustZone, 3) NXP Trust Architecture, 4) AMD SEV, 5) Microsoft …
