摘　　要：基于三相位求值模式提出了一种三相单轨脉冲寄存器(TSPR),该寄存器可在时钟边沿到来之后依次完成放电、充电、写入三个操作.由于输出节点在每个周期内经历一次充电和一次放电操作,因此所有数据处理过程都具有相同功耗,达到了单元功耗与处理数据无关的目的.仿真验证表明TSPR逻辑功能正确,并且具有小于1.73%的归一能量差.进一步采用TSPR实现高级加密标准(AES)算法中的8位S盒结构以验证其抗差分功耗分析(DPA)攻击能力.实验结果证明:TSPR可以将正确密钥与功耗之间的相关性系数降低81.82%,有效地减少数据处理过程中的信息泄露,提高电路的抗攻击能力.A three-phase single-track pulse register(TSPR)based on the three-phase operation mode was proposed.After the arrival of the clock edge,the register sequentially could perform three operations of discharge,pre-charge and evaluate.The output node would experience exactly one charging and one discharging event per cycle,and thereby this logic could have constant energy consumption for all operational data,achieving the purpose that unit power consumption was independent of processing data.Simulations verification shows that TSPR has a correct logic function and exhibits good performances in terms of normalized energy deviation(NED),which is lower than 1.73%.An 8-bit S-box of the advanced encryption standard(AES)algorithm was implemented with TSPR to verify the differential-power-analysis-resistant of the proposed design.Experimental results prove that TSPR can reduce the correlation coefficient between the correct key and power consumption by 81.82%,which could effectively reduce the information leakage during data processing and improve the circuit's resistant.
