摘要: MixColumns/InvMixColumns dominates both the logic resource and critical delay in advanced encryption standard (AES) hardware implementation with direct mapping S-boxes. The proposed decomposition method optimizes area of integrated circuit. Theoretically, short-path circuit reduces up to 42% same 5 XOR gates (Y.-K. Lai et al, 2004) path. When synthesized a TSMC 0.18 mum CMOS technology, has top performance measured AT AT2.
