2D mixed pseudo-random coupling PS map lattice and its application in S-box generation

Abstract: In this paper, firstly, we investigate a new 1D PWLCM-Sin (PS) map which derived from PWLCM and Sin map by modulo operation. Due to the stronger parameter space, bigger Lyapunov exponents and better ergodicity than simple 1D map, the PS map is more suitable for local map of spatiotemporal dynamics. Secondly, with the novel 2D pseudorandom mixed coupling method we present a spatiotemporal chaos which used PS map as local map f(x). This spatiotemporal chaos named 2D Mixed pseudo-random Coupling PS Map Lattice (2… Show more

“…Comparison analysis indicates that our S-box has better ability to resist differential cryptanalysis than S-boxes available in [8,45,48,49,54,60] and it is comparable with others. The LAP score of 0.125 is also slightly better than many Sboxes such as [8,23,45,48,50,[52][53][54][55][56]60,64,65]. But, S-boxes presented in [35,47,58,59,61,62] show better LAP than our S-boxes.…”

“…Table 6 indicates that the proposed Sbox's SAC score is pretty close to 0.5 and better than many recent S-box methods listed in the Table . Moreover, the pair-wise disjoint Boolean functions comprising the S-box should have as high nonlinearity as possible. We can see that the BIC-nonlinearity score of our S-box is 104.2 which is higher than many S-boxes suggested in [8,23,24,45,46,[48][49][50][51][63][64][65] indicating the decent performance of proposed S-box. Hence, the proposed method has the ability to satisfy the SAC and BIC criterions well.…”

“…The main features of the chaotic systems, such as the sensitive dependence on initial conditions and control parameters, ergodicity, size of the parameter space, and mixing property, can be related to the confusion and diffusion conditions that must be applied to information to be protected by using cryptographic systems [22]. Therefore, many cryptographic systems and modules have been proposed based on chaotic systems [22][23][24][25][26][27][28][29][30][31][32][33]. In particular, chaotic maps have been successfully applied in the implementation of PRNGs [14,15,31,[34][35][36][37][38][39][40][41][42].…”
