About this paper
Luca Wilke, Gianluca Scopelliti
SNPGuard introduces a unified, open-source toolchain that enables end-to-end remote attestation and secure secret provisioning for AMD SEV-SNP Virtual Machines. It extends hardware-backed SEV-SNP launch measurements to verify the entire VM boot chain and offers two distinct, verifiable workflows for protecting root filesystem integrity and confidentiality.
Key insights
- Achieving full verifiable trust in CVMs requires extending hardware-backed attestation to encompass the entire boot chain, beyond just the initial firmware.
- Flexible secret provisioning strategies are necessary, ranging from runtime injection to secure early-boot decryption for sensitive root filesystems.
- The integration of existing open-source components into a cohesive workflow can significantly reduce the complexity and manual effort associated with confidential VM deployment and attestation.
