PROFILE
Zhsu
Zhihong Su contributed to the secretflow/spu repository by developing core features that advanced secure multi-party computation and distributed systems. Over four months, he implemented an HTTP-based asynchronous channel for inter-node messaging, added pybind bindings for cross-language support, and delivered comprehensive tests to ensure reliability. He enhanced cryptographic protocols by refactoring truncation logic and introducing precise 2PC algorithms, using C++ and Python to improve correctness and maintainability. Su also focused on build management, updating Bazel configurations and versioning to streamline release tracking and reproducibility. His work demonstrated depth in API development, cryptography, and distributed system engineering within a complex codebase.
