摘要: MDPL has been proposed as a masked logic style that counteracts DPA attacks. Recently, it shown the so-called "early propagation effect" might reduce security of this significantly. In light these findings, 0.13 μmprototype chip includes implementation an 8051-compatible microcontroller in analyzed. Attacks on measured power traces show severe leakage. paper, results detailed analysis reasons for leakage are presented. Furthermore, proposal is made how to improve with respect identified problems.
