A dynamic S-box generation based on a hybrid method of new chaotic system and DNA computing

S-box is one of the most significant structures used to construct encryption that strong and resistant attacks in algorithms. The new 4D-hyper chaotic system deoxyribonucleic acid (DNA) computing are this paper provide a dynamic generating approach. 4D generated numbers processed generate hexadecimal number will encode using DNA coding method addition, subtraction, exclusive-or operations produce final string decoded make S-Box. form s-boxes represented by minor change initial conditions proposed sequences numbers. enhances security criteria block ciphers. testing were done like strict avalanche, balanced, bit independence criteria, addition differential approximation probability linearity probability, test results show has good attacks.
