Here’s a brief summary of the Tech Talk:

  • Diana works on confidential VMs in Google Compute Engine, focusing on AMD and Intel hardware with SEV/P and TDX. Google controls the entire chain for “Confidential Space,” including UEFI, attested container-optimized OS, workload launcher, and verification services.She emphasized the need for a more transparent and trustworthy Trusted Computing Base (TCB) in guest computing contexts. She discussed the challenges and efforts to make UEFI verifiable independently, beyond Google’s internal systems.

    Diana highlighted discrepancies between signed packages and true transparency, advocating for a clearer definition and implementation of transparency in attestation frameworks. She mentioned the role of reference values versus the transparency of those values in the context of security models.

    Ongoing efforts such as Sigstore and Microsoft’s Code Transparency Service aim to enhance transparency across the industry. Diana discussed challenges in reproducibility and the need for better build systems to support transparent UEFI.

    During the Q&A, Diana addressed questions on transparency as endorsement and the operational challenges in maintaining build integrity and security.
