S-Box Design and Image Encryption Based on Hyperchaos

发布时间:2020-12-20 04:17
  In today’s world,there is an ever increasing need for new techniques of maintaining and protecting privacy and integrity of information of mass communication and private information.Chaos theory and cryptography overlap some features which can lead to developing secure chaos-based cryptosystem for secure communication of texts and images.Some of the basic features of chaotic systems such as sensitivity to initial conditions,ergodicity,and pseudorandom behavior,fulfill the analogous requirements ...
