Intel TDX Demystified: A Top-Down Approach. (arXiv:2303.15540v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Intel Trust Domain Extensions (TDX) is a new architectural extension in the
4th Generation Intel Xeon Scalable Processor that supports confidential
computing. TDX allows the deployment of virtual machines in the
Secure-Arbitration Mode (SEAM) with encrypted CPU state and memory, integrity
protection, and remote attestation. TDX aims to enforce hardware-assisted
isolation for virtual machines and minimize the attack surface exposed to host
platforms, which are considered to be untrustworthy or adversarial in the
confidential computing's new threat model. TDX can …
