SPIFFE is a framework to generate identities for software systems in dynamic and heterogeneous environments. SPIFFE Verifiable Identity Documents (SVIDs) enable us to be explicit about the trust we place in systems. However, the degree of trust we can place in SVIDs relies heavily on the soundness of the data gathering and verification process during node attestation. By leveraging confidential computing technologies, specifically Confidential Virtual Machines (CVMs) we can track platform information directly in hardware, including firmware, boot loader, and kernel images, which are then signed with a key rooted inside the CPU itself. By incorporating hardware-protected platform information directly into the SVID generation process, we can significantly enhance the confidence placed in the resulting identity documents. Additionally, consumers of these SVIDs will be able to assert these properties before placing trust in a system.
