- Abstract
Power analysis attack against cryptographic chips is a threatening method, and reverse attack will help to improve the efficiency and success rate of power analysis attack. In order to improve the security of logic circuits in cryptographic chips, this paper applies dummy contacts technology to current-mode CMOS circuits. The designed NAND gate, NOR gate and INV gate have the same circuit structure, plays the role of confusing the attacker's logic, so that the attacker cannot accurately distinguish the logic function of the circuit. On the basis of this design, combined with the characteristics of good power consumption constancy of dual-rail precharge technology, the designed circuit has the ability to resist power analysis attack and reverse attack, and has been verified by Hspice.
