碩士 === 國立宜蘭大學 === 電子工程學系碩士班 === 99 === During the last years, several logic styles that counteract side-channel attacks, e.g. SPA, DPA, have been proposed. Such as Sense Amplifier Base Logic (SABL), Mask Dual-rail Pre-charge Logic (MDPL), Dual-Rail random Switching Logic (DRSL), Three-phase Dual-rail Pre-charge Logic (TDPL), and ect. In this thesis, we depict the TDPL will leakage the information that the circuit operates, and we further modify the TDPL and propose the Three Phase Dual-rail Mask Pre-charge Logic (TDMPL). We use masking technology to randomize to the intermediate operating message, and it is one of the most powerful countermeasures against the DPA attack. The HSpice simulation results reveal the TDMPL guarantees balanced energy consumption, and independent of the processed data. Besides, we implement the TDMPL to AES S-Box. The simulation results exhibit the proposed circuit has good properties to resist DPA.
