PROFILE
Abhinav Saxena
Abhinav Saxena contributed to the open-quantum-safe/liboqs repository, focusing on enhancing cryptographic validation and cross-platform reliability. Over six months, he developed and hardened test suites for ML-KEM and ACVP, implemented FIPS-203 compliant key validation, and introduced Barrett reduction for secure modular arithmetic. His work included refactoring C and Python test harnesses, improving memory safety, and updating CI/CD scripting to support evolving ACVP server versions. By addressing Windows compatibility, refining test logic, and automating vector fetch flows with shell scripting, Abhinav improved both the robustness and maintainability of cryptographic workflows, demonstrating depth in C programming, build systems, and testing.
