Abstract
A chaotic scaled Zhongtang system was applied to generate strong a S-box algorithm [30]. [...]by using a time-delay chaotic system, Özkaynak and Yavuz introduced chaotic S-boxes [29]. A hidden attractor cannot be localized numerically by a standard computational procedure [38,39]. Because there is no limitation of equilibrium, such a chaotic system without equilibrium is appropriate for the area of information encryption [40]. Entropy was used to estimate the transfer rate of information in a particular system [50]. [...]entropy indicates the level of chaos in a dynamical system [51,52]. [...]the system parameters (a,b,c,d) and initial conditions (x(0),y(0),z(0)) of the chaotic system are entered.
