PROFILE
Ceping Sun
During a three-month period, Cepingx Sun developed and integrated foundational support for Intel TDX confidential computing measurements in the acidanthera/audk repository. He architected and implemented new C and UEFI-based APIs for secure attestation, including PCR-to-measurement register mapping, RTMR data hashing, and GUID HOB creation, while refactoring core libraries to improve maintainability. His work included consolidating measurement frameworks, standardizing build system integration, and addressing secure register handling to align with the intel-tdx-module-api. By establishing robust system programming patterns and build-time scaffolding, Cepingx enabled future attestation features and strengthened firmware security for Intel TDX-enabled UEFI environments.

Jan 1, 2025January 2025 — acidanthera/audk: Focused on establishing a foundation for TDX measurement in UEFI. Delivered foundational API surface (TdxMeasurementLib.h) and a NULL placeholder to enable build-time support, enabling build-system integration and future attestation work. Implementations prepare for PCR index mapping, GUID HOBs creation for measurements, and RTMR hashing/extending. No critical bugs fixed this month; outcomes emphasize architectural scaffolding and cross-team readiness using C/Uefi development, header design, and build-system patterns.
