Abstract

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 Pluton, and 6) Apple T2 HRTs in terms of threats, security properties, and capabilities.
