摘　　要：为有效消除密码器件在执行算法时以能量消耗方式泄漏密码信息,本文通过对灵敏放大型逻辑和差分能量攻击原理的研究,采用多电源和多阈值电压(Muti-Supply Muti-Vth,MSMV)CMOS电路技术设计一种具有低功耗和抗差分能量攻击性能的逻辑电路,实现对输出负载低摆幅充放电。依此进一步提出一种新型全加器结构,从而可以以低摆幅的方式对双轨电路进行编码。HSPICE模拟验证表明,所设计的全加器逻辑功能正确,抗差分能量攻击性能明显。与传统基于SABL逻辑的全加器比较,该结构具有显著的低功耗特性。In order to effectively eliminate secret information of cipherware which leaks as energy consumption pattern during algorithms implementation, this paper has employed MSMV technology to design a logic circuit based on the research of SABL and the principle of differential power attack. The proposed logic circuit, which performs with low power consumption and anti-differential power attack, has achieved a feature of very low swing when charging and discharging the output load. A novel full adder structure using such logic is proposed, whose dual rails can be coded in low-swing way. The results by HSPICE simulation show that this full adder has correct logic function and significant property of anti-differential power attack. Compared with traditional full adders based on SABL logic, the proposed architecture has significant property of low power.
