During April 2025, Matziaz enhanced the Matziaz/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 depth in cryptography and hardware description language, with changes clearly isolated for maintainability. Although limited to a single feature, the update established a solid foundation for future inverse-key cryptographic processes.
