Over the past year, contributed to the intel-ipsec-mb repository by building and optimizing cryptographic features for 5G and IPsec workloads. Focused on low-level C and assembly programming, the work included implementing SNOW5G and AES cipher algorithms, integrating AVX2 and AVX512 hardware acceleration, and expanding API and test coverage for secure, high-throughput data paths. Emphasis was placed on performance optimization, secure coding practices, and maintainability through code refactoring and documentation improvements. Parallel processing and buffer management were enhanced to support multi-buffer cryptographic operations, resulting in improved throughput, security posture, and readiness for production deployment in demanding environments.

Mar 1, 2026March 2026 – Key performance and reliability improvements in intel-ipsec-mb. Delivered concurrent OOO management for ZUC-NCA6, enabling safe parallel encryption/decryption and expanded KAT tests for mixed workloads. Implemented a 2-lane SNOW5G NCA4 path with new submission/flush flows and tests; converted NEA4/NIA4 from 8- to 2-lane architecture to boost parallelism and memory efficiency. Added targeted SNOW5G optimizations: LFSR updates using vpternlogq/EVEX and reordering X2 loop FSM clocks to improve throughput and reduce stalls. All changes are accompanied by extended test coverage to ensure correctness in mixed encrypt/decrypt scenarios and across modes. These changes collectively increase throughput, better utilize AVX-512 capabilities, and improve reliability for production workloads.
