Fillipe Souza
Over four months, contributed to the openfhe-development repository by designing and implementing advanced composite scaling techniques for the CKKS homomorphic encryption scheme. Focused on C++ development, the work introduced new scaling modes, robust parameter generation, and enhanced error handling to improve precision and flexibility in encrypted computations. Integrated composite prime moduli sampling and RNS arithmetic for efficient bootstrapping, while refining prime selection and parameter validation to support diverse production workloads. Added comprehensive unit tests, usage examples, and manual testing workflows to ensure reliability and ease of adoption. The contributions emphasized algorithm optimization, code refactoring, and cryptographic correctness throughout the project.
