During April 2025, Matziaz enhanced the TE2002B repository by developing an inverse key schedule capability for cryptographic operations. Focusing on the KeySchedule module, Matziaz implemented the key_schedule_inverse entity in VHDL, enabling generation of all eleven subkeys in reverse order, from Round 10 down to Round 0. This addition supports alternative cryptographic workflows by allowing reverse subkey generation, thereby increasing flexibility and interoperability in digital design. The work demonstrated a strong grasp of cryptography and hardware description languages, with changes clearly isolated and traceable. Although the contribution was focused and deep, it addressed a specific need without introducing bug fixes.
