Zero-Trust vTPM for AMD SEV-SNP Confidential Virtual Machines

Explore the development of a Zero-Trust virtualized Trusted Platform Module (vTPM) for AMD SEV-SNP Confidential Virtual Machines in this KVM Forum presentation. Delve into the evolving use cases for Trusted Execution Environments (TEEs) across cloud, IoT, AI, and multi-party computation. Learn how Confidential VMs leverage hardware-based technologies to protect data in use and provide measurements for VM attestation. Discover the limitations of current attestation methods and the need for a secure TPM in Confidential VMs. Examine the SVSM-vTPM solution, which uniquely identifies Confidential VMs, leverages SEV-SNP protected communication, and creates a Zero-Trust environment protecting data from both the guest OS and hypervisor. Understand how this innovation enables Measured Boot and Linux Integrity Measurement Architecture in Confidential VMs with minimal guest OS changes, utilizing standard TPM interfaces and existing tooling. Gain insights into the contribution of SVSM-vTPM to the AMD Secure VM Service Module (SVSM) open-source project, advancing security in virtualized environments.
