【摘要】：差分功耗分析(Differential Power Analysis,DPA)通过分析密码器件处理不同数据时的功耗差异来盗取密钥。运用具有功耗独立特性的灵敏放大型逻辑(Sense Amplifier Based Logic,SABL)设计密码器件可以有效防御DPA攻击。通过对SABL电路与传统加法器原理的研究,提出了一种能够抗DPA攻击的可重构加法器设计方案。首先,结合SABL电路特点得到具有抗DPA攻击性能的加法器电路;然后利用控制进位方式构成可重构加法器,支持4个8位数据或2个16位数据的加法运算。Spectre模拟验证表明,该加法器逻辑功能正确,与传统加法器相比功耗独立性能提升了97%,防御DPA攻击性能明显。
[Abstract]:Differential Power Analysis (DPA) steals keys by analyzing the power differences of cryptographic devices in processing different data. The design of cryptographic devices using sensitive sense Amplifier Based logic SABLs with power independent characteristics can effectively defend against DPA. Attack. By studying the principle of SABL circuit and traditional adder, In this paper, a design scheme of reconfigurable adder which can resist DPA attack is proposed. Firstly, combining with the characteristics of SABL circuit, the adder circuit with anti-#en2# attack performance is obtained, and then the reconfigurable adder is constructed by using the control carry mode. The simulation results of four 8-bit data or two 16-bit data show that the logic function of the adder is correct, and the power consumption independence performance of the adder is 97% higher than that of the traditional adder, and the performance of defending against DPA attack is obvious.
