Over a three-month period, contributed to the intel-ipsec-mb repository by developing and optimizing cryptographic acceleration features for Kasumi algorithms on AVX2 and AVX-512 architectures. Focused on low-level C and assembly programming, the work involved implementing AVX2-accelerated SBOX and FI functions, introducing architecture-specific SIMD paths, and optimizing encryption throughput for high-performance IPsec workloads. Adjustments included new source files, buffer management, and key schedule flow to maximize performance across different CPUs. Collaborated closely with other contributors, emphasizing performance benchmarking and code review. No major bugs were recorded, and all changes maintained stability while enhancing cryptographic throughput and efficiency.
