Black Hat USA 2024 · Day 1 · Briefing
This talk, presented by Max from Microsoft's Offensive Research and Security Engineering team, delves into a comprehensive security review of **Intel TDX** (Trust Domain Extensions), an emerging confidential computing technology. Conducted in partnership with Intel, the review aimed to scrutinize TDX's architecture and implementation to ascertain whether its ambitious security promises truly hold. TDX represents a critical architectural shift designed to address a fundamental security challenge in cloud environments: protecting customer data even if the underlying cloud provider's hypervisor is compromised.
