Worked on the google/go-tpm-tools repository to deliver GPU attestation integration for RTMR and attestCosState, enhancing security for GPU resources in cloud environments. Developed new features in Go to measure GPU attestation evidence into RTMR with a dedicated event type, improving observability and trust for confidential workloads. Extended attestCosState to expose GPU attestation data, enabling end-to-end visibility across GPU resources. Introduced a dependency on the GCP Confidential Space library to support secure computing scenarios. This work focused on backend development, attestation, and cloud computing, laying the foundation for broader confidential computing use cases involving GPU workloads.
