通过分析双轨电路的主要功耗泄露类型,评估了传统抗功耗攻击逻辑电路的安全性,指出其安全性漏洞。针对其漏洞,对LBDL电路进行改进,并提出了一种将改进后的电路与掩码技术相结合的MLBDL电路。Hspice仿真实验表明,MLBDL电路不仅能够消除由双轨信号布线差异引起的功耗泄露,而且能够消除由输入延时差异引起的功耗泄露,其抗功耗攻击能力显著增强。
By analyzing the main power loss types of dual rail circuits, the security of traditional anti-power attack logic circuits is evaluated and the security vulnerabilities are pointed out. In view of its loopholes, the LBDL circuit is improved, and an MLBDL circuit combining the improved circuit and the mask technology is proposed. Hspice simulation results show that the MLBDL circuit can not only eliminate the power leakage caused by the difference of two-track signal routing, but also eliminate the power leakage caused by the difference of input delay, and its anti-power attack capability is significantly enhanced.
