A Symmetric Chaos-Based Image Cipher with an Improved Bit-Level Permutation Strategy

A Symmetric Chaos-Based Image Cipher with an Improved Bit-Level Permutation Strategy

Very recently, several chaos-based image ciphers using a bit-level permutation have been suggested and shown promising results. Due to the diffusion effect introduced in the permutation stage, the workload of the time-consuming diffusion stage is reduced, and hence the performance of the cryptosyste...
