Design of circuit against power analysis attacks based on masking technology
The confusion characteristic of masking technology can increase the difficulty of attackers to analyze the logic value of the circuit,and the combination of masking technology and Dual-Rail Precharge(DRP)technology can further play a role in resisting power analysis attacks.The application of masking technology and dual-rail precharge technology requires corresponding processing of the input signals and output signals.Based on this,this paper proposes a single rail to dual-rail conversion logic circuit,which can realize the conversion of signal.Then a mask logic conversion circuit is proposed,which can realize the conversion of the output value of the circuit according to the mask value.At last,a single-dual rail mask logic structure is proposed to form a circuit design scheme with power attack resistance.The above logic circuits have been verified by Hspice simulation and have correct logic functions,which provides a way for the circuit design against power analysis attacks.
