During May 2025, Backman focused on enhancing cryptographic support for embedded systems in the wolfSSL/wolfssl repository. He integrated ML-KEM-based Kyber cryptography for ARM targets within the Zephyr RTOS by replacing the existing kyber-asm_c.c implementation with mlkem-asm_c.c, aligning the build system with emerging post-quantum standards. This work required in-depth knowledge of C, CMake, and embedded build systems, ensuring compatibility with Zephyr’s configuration while preparing the codebase for future hardware acceleration. Although the contribution was limited to a single feature, it demonstrated a focused and technically sound approach to modernizing cryptographic primitives for secure, maintainable embedded deployments.
