抗差分电磁分析逻辑电路研究
Research on Logic Circuit Against DEMA
摘要
Abstract
The defending ability of Dynamic Differential Cascade Voltage Switch Logic(DDCVSL) and SABL is restricted by layout and routing when they are used for protecting the circuit against differenfal electromagnetic analysis.Aiming at this problem, this paper gives an improved defend logic Masked Dynamic Differenfal Cascade Voltage Switch Logic(MDDCVSL) based on DDCVSL through introducing masking mechanism.NAND gates based on MDDCVSL, DDCVSL and SABL are designed with TSMC 0.18 μm technology.Experimental result demonstrates that the improved defend logic get rid of the electromagnetic information leakage and solve the problem that defend ability of MDDCVSL, DDCVSL and SABL are restricted by layout and routing.Meanwhile, MDDCVSL has less power consumption, area and delay than WDDL, MDPL.关键词
