Abstract: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.
