Fast algorithm to search for the minimum number of active S-boxes of block cipher by Zhengbin LIU, Yongqiang LI, Chaoxi ZHU

“…To solve the problem of fast calculation of the minimum number of active S-boxes in cryptographic design, the difference and mask propagation of the diffusion layer were investigated, and a method was proposed to compute the difference (resp.mask) pattern distribution table of MDS (maximum distance separable) matrices and binary matrices.A lower bound on the computation complexity of the proposed method was also given.Based on the difference (resp.mask) pattern distribution table of diffusion matrix, a fast algorithm to search for the minimum number of active S-boxes of block cipher was proposed.The proposed algorithm is applied to some SPN (substitution permutation network) block ciphers, and finds the minimum number of active S-boxes for the full round of LED, SKINNY, CRAFT and FIDES.…”

Optimal approximation model of autocorrelation function of digital image by CHENG Xiao-gang1, CHEN Qi-mei1, CHENG Hao2, LIU Guo-qing2, AN Ming-wei1

“…Non-stationary stochastic signal was divided into piecewise stationary stochastic signal,and reflecting the sig-nal’s characteristics by autocorrelation function of the piecewise stationary stochastic signal.Generally,the autocorrela-tion function was the base of selecting signal base for signal representation.For expressing non-stationary stochastic sig-nal in a precise and effective way,based on the analysis of the natural characteristics of ARMA model and Markov proc-ess,a kind of multi-parameter estimation model of autocorrelation function for piecewise stationary stochastic process was proposed.The computational complexity was reduced,and the approximation effect was improved.Furthermore,the multi-parameter estimation model could also be adapted to the complex non-stationary stochastic signal,The computer simulation demonstrates that the approximation error was decreased significantly.…”
