Confidential Computing Architecture: AMD SEV-SNP Reverse Map Tables vs. Intel TDX DRAM Encryption

Canonical Research Note: Originally published by the TrendSpike Institutional Systems & Quantitative Finance Desk. Full AES-128-XTS physical address tweak equations and RMP/S-EPT architectural comparisons are available in the primary publication.

Eliminating the Hypervisor from the Cloud Trusted Computing Base (TCB)

Modern Confidential VMs rely on inline AES-128-XTS memory controller cryptography and hardware Reverse Map Tables (RMP) to prevent privileged hypervisor memory inspection and page-table remapping attacks.
