The HINDMARSH-ROSE SYSTEM

1- We obtain 10^6 data from Hindmarsh-Rose choatic dynamical system by the four-step Runge-Kutta method, see MATT1-MATT2-MATT3-MATT4.-------------------------------------------------2- We get 256 values from MATT2.txt. See a1 and a2.---------------------------------------------------3- We sort the a1.txt and a2.txt files incrementally. Outputs are called b1 and b2.-----------------------------------------------------4- We obtain S-boxes 1,2,3 and 4 by algorithms 1.---------------------------------------------------5- The Sbox5.txt is obtained by zigzag transform in algorithm 2.
