PROFILE
Zhsu
Zhihong Su contributed to the secretflow/spu repository by developing and refining core cryptographic and build management features over a three-month period. He enhanced the robustness and correctness of kernel-level operations such as permutation, sorting, and SOPRF, directly improving the reliability of secure multi-party computation workflows. Using C++, Python, and Bazel, he implemented new truncation and multiplication protocols, refactored truncation logic for greater precision, and introduced a more accurate 2PC truncation algorithm. Su also focused on release management by updating versioning across configuration files, which improved build traceability, reproducibility, and streamlined the CI/CD process for ongoing development.

May 1, 2025May 2025 performance summary for secretflow/spu focusing on release management and build traceability. Delivered development versioning and release tracking by updating version numbers across multiple configuration and header files to reflect a new dev build 0.9.4.dev20250522, enabling precise dev-build identification and streamlined release management. This work was validated by commit 26c23f101f038e248e6c258f9f6971a49a3e4374 ("bump version to 0.9.4.dev20250522 (#1146)"). No major user-facing bugs fixed this month; the emphasis was on stabilizing the dev-build process and improving release management. Overall impact includes improved reproducibility of dev builds, clearer release tracking, and stronger CI/CD readiness. Technologies/skills demonstrated include version control discipline, multi-file configuration updates, and release-management practices.
