Murattoprak Toprak contributed to the google/heir repository by expanding the cryptographic dialect capabilities within the OpenFHE dialect. He developed extended-basis rotation operations, implementing fast rotation in the extended Chinese Remainder Theorem (CRT) basis to enable more efficient cryptographic computations and lay the foundation for future key-switching workflows. Using C++, cryptography, and MLIR, Murattoprak focused on enhancing the flexibility and performance of cryptographic workflows without addressing major bug fixes during this period. His work provided a deeper technical foundation for extended CRT basis functionality, positioning the project for future optimizations and supporting more advanced cryptographic operations moving forward.
