A new CPA resistant software implementation for symmetric ciphers with smoothed power consumption: SIMON case study
In this paper we propose a new method for applying hiding countermeasure against CPA attacks. This method is for software implementation, based on smoothing power consumption of the device. This method is evaluated on the SIMON scheme as a case study; however, it is not relying on any specific SIMON features. Our new method includes only AND equivalent and XOR equivalent operations since every ...
متن کاملA New Circuit Scheme for Wide Dynamic Circuits
In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...
متن کاملOn Relationships among Avalanche, Nonlinearity, and Correlation Immunity
We establish, for the first time, an explicit and simple lower bound on the nonlinearity Nf of a Boolean function f of n variables satisfying the avalanche criterion of degree p, namely, Nf ≥ 2n−1 − 2n−1− 1 2 . We also show that the lower bound is tight, and identify all the functions whose nonlinearity attains the lower bound. As a further contribution of this paper, we prove that except for v...
متن کاملThe role of microRNAs and phytohormones in plant immune system
The plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. During the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ROS signaling, hormone activation and gene expression reprogramming. In plants, microRNAs (miRNAs) are key post-transcript...
متن کاملRevisiting Correlation-Immunity in Filter Generators
Correlation-immunity is a cryptographic criterion on Boolean functions arising from correlation attacks on combining functions. When it comes to filtering functions, the status of correlation-immunity lacks study in itself and, if it is commonly accepted as a requirement for nonlinear filter generators, this is for other concerns. We revisit the concept of correlation-immunity and clear up its ...
