PROFILE
Armon Chojnacki
Worked on the intel-ipsec-mb repository to enhance AES-CFB decryption performance and maintainability using Assembly and SSE intrinsics. Delivered a parallelized decryption path that processes up to eight blocks concurrently, increasing throughput and reducing latency for encrypted IPsec workloads. Focused on low-level optimization and vectorization to improve CPU efficiency while preserving API compatibility and integration with existing tests. Subsequently refactored the AES_CFB_DEC parallel processing logic, consolidating input checks to reduce code duplication and improve readability. Emphasized maintainable, scalable assembly code, laying a foundation for future optimizations and facilitating easier onboarding for engineers working on cryptographic data paths.
