“…In recent years, chaotic maps such as logistic map, exponential map, 2D Baker map, Chebyshev map, Tent map, Lorenz system, 3D fourwing autonomous chaotic system, chaotic scaled Zhongtang system, logistic-sine map, fractional-order chaotic Chen system etc. are widely used for random S-box design (Belazi, Khan, Abd El-Latif, & Belghith, 2016;Cavusoglu, Zengin, Pehlivan, & Kacar, 2016;Chen, 2008;Jakimoski & Kocarev, 2001;Lambić, 2014;Liu, Yang, Liu, & Dai, 2015;Ozkaynak, Celik, & Ozer, 2016;Ozkaynak & Ozer, 2010;Wang, Wong, Liao, & Xiang, 2009). Besides these, there are many other methods for the generation of random S-boxes based on various chaotic maps, which to our knowledge all have continuous space domain, except for the method presented in Lambić (2017).…”
