针对DPA(差分功率分析)和二阶DPA，在逻辑层面上提出了一种新的对抗方法--随机开关逻辑(RSL)。RSL使每个栅极的信号转换统一，并抑制毛刺的传播，以允许功耗独立于可预测的数据。利用RSL在现场可编程门阵列(现场可编程门阵列)上实现了基本逻辑电路，并对其有效性进行了评估。因此，我们确认了可以针对DPA和二阶DPA构造安全电路的事实。
This paper proposes a new countermeasure, Random Switching Logic (RSL), against DPA (Differential Power Analysis) and Second-Order DPA at the logic level. RSL makes a signal transition uniform at each gate and suppresses the propagation of glitch to allow power consumption to be independent of predictable data. Furthermore, we implement basic logic circuits on the FPGA (Field Programmable Gate Array) by using RSL, and evaluate the effectiveness. As a result, we confirm the fact that the secure circuit can be structured against DPA and Second-Order DPA.
